• Need help with WCF design

  - by Jason

  I have been tasked with creating a set of web services. We are a Microsoft shop, so I will be using WCF for this project. There is an interesting design consideration that I haven't been able to figure out a solution for yet. I'll try to explain it with an example: My WCF service exposes a method named Foo(). 10 different users call Foo() at roughly the same time. I have 5 special resources called R1, R2, R3, R4, and R5. We don't really need to know what the resource is, other than the fact that a particular resource can only be in use by one caller at a time. Foo() is responsible to performing an action using one of these special resources. So, in a round-robin fashion, Foo() needs to find a resource that is not in use. If no resources are available, it must wait for one to be freed up. At first, this seems like an easy task. I could maybe create a singleton that keeps track of which resources are currently in use. The big problem is the fact that I need this solution to be viable in a web farm scenario. I'm sure there is a good solution to this problem, but I've just never run across this scenario before. I need some sort of resource tracker / provider that can be shared between multiple WCF hosts. Any ideas from the architects out there would be greatly appreciated!

• Is there a library that can decompile a method into an Expression tree, with support for CLR 4.0?

  - by Daniel Earwicker

  Previous questions have asked if it is possible to turn compiled delegates into expression trees, for example: http://stackoverflow.com/questions/767733/converting-a-net-funct-to-a-net-expressionfunct The sane answers at the time were: It's possible, but very hard and there's no standard library solution. Use Reflector! But fortunately there are some greatly-insane/insanely-great people out there who like reverse engineering things, and they make difficult things easy for the rest of us. Clearly it is possible to decompile IL to C#, as Reflector does it, and so you could in principle instead target CLR 4.0 expression trees with support for all statement types. This is interesting because it wouldn't matter if the compiler's built-in special support for Expression<> lambdas is never extended to support building statement expression trees in the compiler. A library solution could fill the gap. We would then have a high-level starting point for writing aspect-like manipulations of code without having to mess with raw IL. As noted in the answers to the above linked question, there are some promising signs but I haven't succeeded in finding if there's been much progress since by searching. So has anyone finished this job, or got very far with it? Note: CLR 4.0 is now released. Time for another look-see.

• How do I find the module dependencies of my Perl script?

  - by zoul

  I want another developer to run a Perl script I have written. The script uses many CPAN modules that have to be installed before the script can be run. Is it possible to make the script (or the perl binary) to dump a list of all the missing modules? Perl prints out the missing modules’ names when I attempt to run the script, but this is verbose and does not list all the missing modules at once. I’d like to do something like: $ cpan -i `said-script --list-deps` Or even: $ list-deps said-script > required-modules # on my machine $ cpan -i `cat required-modules` # on his machine Is there a simple way to do it? This is not a show stopper, but I would like to make the other developer’s life easier. (The required modules are sprinkled across several files, so that it’s not easy for me to make the list by hand without missing anything. I know about PAR, but it seems a bit too complicated for what I want.) Update: Thanks, Manni, that will do. I did not know about %INC, I only knew about @INC. I settled with something like this: print join("\n", map { s|/|::|g; s|\.pm$||; $_ } keys %INC); Which prints out: Moose::Meta::TypeConstraint::Registry Moose::Meta::Role::Application::ToClass Class::C3 List::Util Imager::Color … Looks like this will work.

• Allow selection of readonly files from SaveFileDialog?

  - by Andy Dent

  I'm using Microsoft.Win32.SaveFileDialog in an app where all files are saved as readonly but the user needs to be able to choose existing files. The existing files being replaced are renamed eg: blah.png becomes blah.png-0.bak, blah.png-1.bak and so on. Thus, the language for the OverwritePrompt is inappropriate - we are not allowing them to overwrite files - so I'm setting dlog.OverwritePrompt = false; The initial filenames for the dialog are generated based on document values so for them, it's easy - we rename the candidate file in advance and if the user cancels or chooses a different name, rename it back again. When I delivered the feature, testers swiftly complained because they wanted to repeatedly save files with names different from the agreed workflow (those goofy, playful guys!). I can't figure out a way to do this with the standard dialogs, in a way that will run safely on both XP (for now) and Windows 7. I was hoping to hook into the FileOK event but that is called after I get a warning dialog: |-----------------------------------------| | blah.png | | This file is set to read-only. | | Try again with a different file name. | |-----------------------------------------|

• .Net Architecture challenge: The Change-prone Frankestein Model

  - by SDReyes

  Good Morning SO! We've been scratching our heads with with this interesting scenario at the office, and we're anxious to hear your ideas and approaches: We have a database, whose schema is prone to changes -lets call it Prony-. (is used to store configuration parameters for embedded devices. so if the embedded devices guy need a new table, property or relationship for the model, he should be able to adapt the schema in a easy way -happens so often- ). Prony needs a web interface to create/edit its data. We have another database containing data that also need to be loaded to the devices, after making some transformations - lets call this one Oddy- (this data it's generated by an already existent administrative web application). Finally we have Tracy, a server that communicates our DBs and our embedded devices. She should to auto-adapt herself, to our dbs schema changes and serialize the data to the devices. Nice puzzle, don't think so? : ) Our current candidates: Rady: The fast Lets create some views in Prony that make the data transformation from Oddy. then use DynamicData (or some RAD tool) to create/update a simple web interface for Prony (so he can even consult the transformated data from coming from Prony : ). About Tracy, she will need to be recompiled to update her DB schema (Entity framework should work) and use Reflection to explore recursively the schema and serialize data. Cons: We would have to recompile Tracy and the Prony's web interface. What do you think of the candidate(s)? What would you do?

• Need some help to determine the amount of recursive calls in PHP

  - by Ben Fransen

  Hi all, I've got a, I think fairly easy question, but this is bugging me for a while now. So I figured, maybe I can get some help here. Since recursive functions are always a bit tricky, and sometimes a bit unclear to me, I keep struggling to create a nice working solution to get my menudata. In one of my classes I have this function, which gives me all menu-items recursivly. The thing I want is to determine at which recursionlevel a certain object was retrieved so I can create a nicely looking HTML output with indents for the levels of nesting. public function GetObjectList($parentID = 0, $objectlist = null) { if(is_null($objectlist)) { $objectlist = new ObjectList("Model_Navigation"); } $query = MySQL::Query("SELECT * FROM `Navigation` WHERE `WebsiteID` = ".SITE_ID. " AND `LanguageID` = ".LANG_ID." AND `ParentID` = ".$parentID); while($result = MySQL::FetchAssoc($query)) { $object = new Model_Navigation(); $object->ID = $result["ID"]; $object->WebsiteID = $result["WebsiteID"]; $object->LanguageID = $result["LanguageID"]; $object->ParentID = $result["ParentID"]; $object->Name = $result["Name"]; $object->Page = Model_Page::GetObjectByID($result["PageID"]); $object->ExternalURL = $result["ExternalURL"]; $object->Index = $result["Index"]; $object->Level = [here lies my problem]; $objectlist->Add($object); self::GetObjectList($object->ID, $objectlist); } return $objectlist; } Hope to hear from you! Greetings from Holland, Ben Fransen

• Codeplex/Sourceforge for internal use

  - by Josh

  I'm looking for a free/open source collaborative project manager that can be deployed internally in my workplace that would act similar to Codeplex or Sourceforge. Does anyone know of something like this, and if so do you have experience with it. Requirements: Open Source or Free Locally Deployable Has the same types of features found in Sourceforge / Codeplex Issue/Feature Tracking Community Interaction (ie. Voting, Roles, etc.) SCM Integration (Optional) .NET/Windows Friendly (Optional) Every business ends up having internal utilities, and domain specific apps that developers create to make life easier. Given the input of the internal developer community they have the potential to become much better (can you say GMail...), and I would simply like to foster such an environment internally by providing an easy place for that interaction to take place. UPDATE: So I like what I am seeing in both Trac and GForge, but both are heavily geared towards UNIX/Subversion environments. I should have specified this, but we are a MS shop from top to bottom. How practical do you think it is going to be to try and use these in a MS .NET environment? Would that be like trying to shove a square peg through a round hole?

• How can I do rapid application development with ASP.NET MVC?

  - by Erik Forbes

  I've been given a short amount of time (~80 hours to start with) to replace an existing Access database with a full-blown SQL + Web system, and I'm enumerating my options. I would like to use ASP.NET MVC, but I'm unsure of how to use it effectively with my short timetable. For the database backend I'll be using Linq to SQL as it's a product I already know and can get something working with it quickly. Does anyone have any experience with using ASP.NET MVC in this way and can share some insight? Edit: The reason I've been interested in ASP.NET MVC is because I know (100% confirmed) that there will be more work to do after this first round, and I'd like my maintenance work to be as easy as possible. In my experience Webforms applications tend to break down over repeated maintenance, despite discipline. Maybe there's a middle ground? How difficult would it to be for me to, say, build the app with Webforms, then migrate it to MVC later when I have more time budgeted to the project? Edit 2: Further background: the Access application I'm replacing is used in some capacity by everyone in the building, and since it was upgraded from Access 98 to 2003 it's been crashing daily, causing hours of lost productivity as people have to re-enter data since the last backup. This is the reason for the short amount of time - this is a critical business function, and they can't afford to keep re-entering data on a daily basis.

• How to implement menuitems that depend on current selection in WPF MVVM explorer-like application

  - by Doug

  I am new to WPF and MVVM, and I am working on an application utilizing both. The application is similar to windows explorer, so consider an app with a main window with menu (ShellViewModel), a tree control (TreeViewModel), and a list control (ListViewModel). I want to implement menu items such as Edit - Delete, which deletes the currently selected item (which may be in the tree or in the list). I am using Josh Smith's RelayCommand, and binding the menuitem to a DeleteItemCommand in the ShellViewModel is easy. It seems like implementing the DeleteItemCommand, however, requires some fairly tight coupling between the ShellViewModel and the two child view models (TreeViewModel and ListViewModel) to keep track of the focus/selection and direct the action to the proper child for implementation. That seems wrong to me, and makes me think I'm missing something. Writing a focus manager and/or selection manager to do the bookkeeping does not seem too hard, and could be done without coupling the classes together. The windowing system is already keeping track of which view has the focus, and it seems like I'd be duplicating code. What I'm not sure about is how I would route the command from the ShellViewModel down to either the ListViewModel or the TreeViewModel to do the actual work without making a mess of the code. Some day, the application will be extended to include more than two children, and I want the shell to be as ignorant of the children as possible to make that extension as painless as possible. Looking at some sample WPF/MVVM applications (Karl Shifflett's CipherText, Josh Smith's MVVM Demo, etc.), I haven't seen any code that does this (or I didn't understand it). Regardless of whether you think my approach is way off base or I'm just missing a small nuance, please share your thoughts and help me get back on track. Thanks!

• Are short tags *that* bad?

  - by Col. Shrapnel

  Everyone here on SO says it's bad, for 3 main reasons: XML is used everywhere You can't control where your script is going to be run short tags are going to be removed in PHP6 But let's see closer at them: Last one is easy - it's just not true. XML is not really a problem. If you want to use short tags, it won't be a problem for you to write a single tag using PHP echo, <?="<?XML...?>"?>. Anyway, why not to leave such a trifle thing for one's own judgment? PHP configuration access. Oh yes, the only thing that can be really considered as a reason. Of course in case you plan to spread your code wide. But if you don't? I think most of scripts being written not for the wide spread, but just for one place. If you can use short tags in that place - why to abandon them? Anyway, it's the only template we are talking about. If you don't like short tags, PHP native template is probably not for you, why not to try Smarty then? Well, the question is: is there any other real reasons to abandon short tags and make it strict recommendation? Or, as it was said, better to leave short tags alone?

• how to use Remote Service ?

  - by LEE YONGGUN

  Hi im trying to use Remote Service btween two simple application, But its not easy to me. So any advice you have will help me. here`s my case. I made one app which is playing Music in service, There are two components. one is Activity controlling service by using three buttons, play,pause, stop. and it is working fine. and another one is just simple Activity which also has four buttons bind,play,stop,unbind. when i click bind, it`s confirmed by Toast msg, but when i click play button,it occurs error. i want to control first activitys Music playing service in second Activity. So im trying to use remote service. i made same .aidl file in each app project. In aidl file, i defined methods "playing","stoping" and i implement those methods in Music service class, implementation is simply use intent and startService & stopService.

• Playing wave file ends immediatly (C++, Windows)

  - by TyBoer

  I've got a following situation. On a machine there is a Fritz ISDN card. There is a process that is responsible for playing a certain wave file on this device's wave out (ISDN connection is made at startup and made persistent). The scenario is easy, whenever needed the process calls waveOutWrite() on the previously opened wave device (everything initialized without any problems of course) and a callback function waits for MMWOMDONE msg to know that the playback has been finished. Since a few days however (nothing changed neither in the process nor the machine) the MMWOMDONE message comes immediately after calling waveOutWrite() even though the wave lasts a couple of seconds. Again no error is reported, it looks like the file was played but had zero length (which is not the case). I am also sure that waveOutReset() was not called by my process (it would also trigger sending the mentioned message). I already used to have some strange problems in the past that where solved simply by reinstalling TAPI drivers. This time for some reason it is problematic form me to perform that once again and am trying more analytical approach :). Any suggestions what might cause such a behavior? Maybe sth on the other end of the ISDN line?

• Pros and cons of MPMoviePlayerController versus launching UIWebView to stream movie

  - by Nosredna

  I have a client who has video content for the web in Flash format. My task is to help them show the videos in an iPhone app. I realize that step one is to get these videos into the appropriate Quicktime format for the iPhone. Then I'm going to have to help the client figure out how or where to host these files. If that's tricky I assume they can be hosted at YouTube. My chief concern, though, is which approach to take to stream the video. What are the pros and cons of MPMoviePlayerController versus launching UIWebView with the URL of the stream? Is there any difference? Is one of them more or less forgiving? Is one of them a better user experience? Any gotchas I might expect to run into? I'm assuming playing video is pretty easy on the iPhone. Is it reasonable to try both and have one available as a fallback, or would that be a waste of time? I'm trying to schedule this out a bit, so I'd love to hear real-world experiences from anyone who's done this.

• StructureMap problems with bidirectional/circular dependencies

  - by leozilla

  I am currently integrating StructureMap within our business layer but have problems because of bidirectional dependencies. The layer contains multiple manager where each manager can call methods on each other, there are no restrictions or rules for communication. This also includes possible circular dependencies like in the example below. I know the design itself is questionable but currently we just want StructureMap to work and will focus on further refactoring in the future. Every manager implements the IManager interface internal interface IManager { bool IsStarted { get; } void Start(); void Stop(); } And does also have his own specific interface. internal interface IManagerA : IManager { void ALogic(); } internal interface IManagerB : IManager { void BLogic(); } Here are to dummy manager implementations. internal class ManagerA : IManagerA { public IManagerB ManagerB { get; set; } public void ALogic() { } public bool IsStarted { get; private set; } public void Start() { } public void Stop() { } } internal class ManagerB : IManagerB { public IManagerA ManagerA { get; set; } public void BLogic() { } public bool IsStarted { get; private set; } public void Start() { } public void Stop() { } } Here is the StructureMap configuration i use atm. I am still not sure how i should register the managers so currently i use a manual registration. Maybee someone could help me with this too. For<IManagerA>().Singleton().Use<ManagerA>(); For<IManagerB>().Singleton().Use<ManagerB>(); SetAllProperties(convention => { // configure the property injection for all managers convention.Matching(prop => typeof(IManager).IsAssignableFrom(prop.PropertyType)); }); After all i cannot create IManagerA because StructureMap complians about the circular dependency between ManagerA and ManagerB. Is there an easy and clean solution to solve this problem but keep to current design? br David

• Combining properties made available via webservices profile service aspnet

  - by Adam

  I really wasn't sure what the title for my question could be, so sorry if it's a bit vague. I'm working on an application that uses client application services for authentication/profile management etc. In web.config for my website, I have the following profile properties like this: <properties> <add name="FirstName" type="string" defaultValue="" customProviderData="FirstName;nvarchar"/> ... Basic things like first name, last name etc. I'm exposing properties for my client app like this: <system.web.extensions> <scripting> <webServices> <authenticationService enabled="true" requireSSL="false"/> <profileService enabled="true" readAccessProperties="UserProfile" writeAccessProperties="UserProfile"/> <roleService enabled="true"/> </webServices> </scripting> </system.web.extensions> What I'm wondering is whether it's possible to bundle all the individual profile properties into a single object for client apps to utilize? I originally had all my profile data stored as members of a single class (UserProfile) but I broke it all out so that I could use the SqlTableProfileProvider to store each field as individual columns in relevant tables. I know I can create an class with members for each type, I'm just not sure if there's an easy way to create an object with all my property values (other than assigning values to this object whenever I assign to the the standalone properties). I don't think I'm explaining this very well, so I'll try an example. Say in my website profile I have FirstName and LastName as properties. For my client application profileService I want to have one ReadAccessProperty FullName. Is there some way to automatically create FullName from the existing FirstName and LastName properties without having to also have a seperate FullName property (and manually assign data to it whenever I assign data to FirstName and LastName)?

• rpy2: Converting a data.frame to a numpy array

  - by Mike Dewar

  I have a data.frame in R. It contains a lot of data : gene expression levels from many (125) arrays. I'd like the data in Python, due mostly to my incompetence in R and the fact that this was supposed to be a 30 minute job. I would like the following code to work. To understand this code, know that the variable path contains the full path to my data set which, when loaded, gives me a variable called immgen. Know that immgen is an object (a Bioconductor ExpressionSet object) and that exprs(immgen) returns a data frame with 125 columns (experiments) and tens of thousands of rows (named genes). robjects.r("load('%s')"%path) # loads immgen e = robjects.r['data.frame']("exprs(immgen)") expression_data = np.array(e) This code runs, but expression_data is simply array([[1]]). I'm pretty sure that e doesn't represent the data frame generated by exprs() due to things like: In [40]: e._get_ncol() Out[40]: 1 In [41]: e._get_nrow() Out[41]: 1 But then again who knows? Even if e did represent my data.frame, that it doesn't convert straight to an array would be fair enough - a data frame has more in it than an array (rownames and colnames) and so maybe life shouldn't be this easy. However I still can't work out how to perform the conversion. The documentation is a bit too terse for me, though my limited understanding of the headings in the docs implies that this should be possible. Anyone any thoughts?

• Can I combine two functions into one using Javascript?

  - by Melissa

  I have the following code that I would like to simplify. With javascript and jQuery is there an easy way that I could combine these two functions? Most of the code is the same but I am not sure how I could create a single function that works differently depending on what is clicked. $(document).ready(function () { $('#ListBooks').click(ListBooks); $('#Create').click(Create); }); function Create() { var dataSourceID = $('#DataSourceID').val(); var subjectID = $('#SubjectID').val(); var contentID = $('#ContentID').val(); if (dataSourceID && dataSourceID != '00' && subjectID && subjectID != "00" && contentID && contentID != "00") { var e = encodeURIComponent, arr = ["dataSourceID=" + e(dataSourceID), "subjectID=" + e(subjectID), "contentID=" + e(contentID)]; window.location.href = '/Administration/Books/Create?' + arr.join("&"); } else { alert('Datasource, Subject and Content must be selected.'); } return false; } function ListBooks() { var dataSourceID = $('#DataSourceID').val(); var subjectID = $('#SubjectID').val(); var contentID = $('#ContentID').val(); if (dataSourceID && dataSourceID != '00' && subjectID && subjectID != "00" && contentID && contentID != "00") { var e = encodeURIComponent, arr = ["dataSourceID=" + e(dataSourceID), "subjectID=" + e(subjectID), "contentID=" + e(contentID)]; window.location.href = '/Administration/Books/ListBooks?' + arr.join("&"); } else { alert('Datasource, Subject and Content must be selected.'); } return false; }

• Javascript conversion, from Prototype to jQuery

  - by moshimoshi

  Hi, I would like to update the following javascript code based on Prototype framework to jQuery framework: Event.observe(window, 'load', function() { $$('.piece').each(function(item) { new Draggable(item, { revert: true } ); }); $$('.cell').each(function(item) { Droppables.add(item, { accept: 'piece', onDrop: function(piece, cell) { cell.descendants().each(function(item) { item.remove(); } ); piece.remove(); piece.setStyle({ 'top': null, 'left': null }); new Draggable(piece, { revert: true }); cell.appendChild(piece); } }); }); }); The first part of the script is easy to convert: $(function() { $('.piece').draggable( { evert: true } ); $('.cell').droppable( { /* But here, it's more difficult. Right? ;) ... */ } }); }); Have you got an idea? Any part of code is welcome. Thanks a lot.

• Is there a good way of automatically generating javascript client code from server side python

  - by tat.wright

  I basically want to be able to: Write a few functions in python (with the minimum amount of extra meta data) Turn these functions into a web service (with the minimum of effort / boiler plate) Automatically generate some javascript functions / objects for rpc (this should prevent me from doing as many stupid things as possible like mistyping method names, forgetting the names of methods, passing the wrong number of arguments) Example python: def hello_world(): return "Hello world" javascript: ... <!-- This file is automatically generated (either dynamically or statically) --> <script src="http://myurl.com/webservice/client_side_javascript"> </script> ... <script> $('#button').click(function () { hello_world(function (data){ $('#label').text(data))) } </script> A bit of research has shown me some approaches that come close to this: Automatic generation of json-rpc services from functions with a little boiler plate code in python and then using jquery and json to do the calls (still easy to make mistakes with method names - still need to be aware of urls when calling, very irritating to write these calls yourself in the firebug shell) Using a library like soaplib to generate wsdl from python (by adding copious type information). And then somehow convert this into javascript (not sure if there is even a library to do this) But are there any approaches closer to what I want?

• Converting Makefile to Visual Studio Terminology Questions (First time using VS)

  - by Ukko

  I am an old Unix guy who is converting a makefile based project over to Microsoft Visual Studio, I got tasked with this because I understand the Makefile which chokes VS's automatic import tools. I am sure there is a better way than what I am doing but we are making things fit into the customer's environment and that is driving my choices. So gmake is not a valid answer, even if it is the right one ;-) I just have a couple of questions on terminology that I think will be easy for an experienced (or junior) user to answer. Presently, a make all will generate several executables and a shared library. How should I structure this? Is it one "solution" with multiple projects? There is a body of common code (say 50%) that is shared between the various executable targets that is not in a formal library, if that matters. I thought I could just set up the first executable and then add targets for the others, but that does not seem to work. I know I am working against the tool, so what is the right way? I am also using Visual C++ 2010 Express to try and do this so that may also be a problem if support for multiple targets is not supported without using Visual C++ 2010 (insert superlative). Thanks, this is really one of those questions that should be answerable by a quick chat with the resident Windows Developer at the water cooler. So, I am asking at the virtual water cooler, I also spring for a virtual frosty beverage after work.

• How to access device settings on a Sony Ericsson mobile phone?

  - by TheRHCP

  Edited on April 29th Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks. EDIT: It seems that I was totally wrong concerning my phone. This not based on any Symbian OS at all. This is pure Sony Ericsson so the only solution would be to look if Sony Ericsson extended J2ME functionality in their own JVM. I am gonna investigate on this.

• PHP / C++ space calculations for parcel packing

  I am working on a shopping cart project which requires a 'postage calculator' based on items that the person has in their cart. Obviously I will be storing the item's dimensions incl. weight and padding in a database and will also store the parcel (box) size and weight that the items will go in to, incl. box padding. Figuring the weight of the parcels will be easy but I was wondering how to go about figuring how to pack the box via PHP, that is, I would like the code to 'play tetris' with the items to make sure they get the best possible fit, giving accurate postage costs. Does anybody have any ideas on how best to achieve this or does anybody know of a PHP Class or function that can do this? EDIT: When I said 'best possible fit' maybe I was being optimistic! Having the script try every possible combination of package distribution within the parcel would be over the top, however I could improve the speed by writing the algoritm in C++ and running the program in PHP when the user 'checks out', the return value being an array with the parcel size and weight (which are all that are needed to calculate postage costs)

• How to join a table in symfony (Propel) and retrieve object from both table with one query

  - by Jean-Philippe

  Hi, I'm trying to get an easy way to fetch data from two joined Mysql table using Propel (inside Symfony) but in one query. Let's say I do this simple thing: $comment = CommentPeer::RetrieveByPk(1); print $comment->getArticle()->getTitle(); //Assuming the Article table is joined to the Comment table Symfony will call 2 queries to get that done. The first one to get the Comment row and the next one to get the Article row linked to the comment one. Now, I am trying to find a way to make all that within one query. I've tried to join them using $c = new Criteria(); $c->addJoin(CommentPeer::ARTICLE_ID, ArticlePeer::ID); $c->add(CommentPeer::ID, 1); $comment = CommentPeer::doSelectOne($c); But when I try to get the Article object using $comment->getArticle() It will still issue the query to get the Article row. I could easily clear all the selected columns and select the columns I need but that would not give me the Propel object I'd like, just an array of the query's raw result. So how can I get a populated propel object of two (or more) joined table with only one query? Thanks, JP

• Update mapping table in Linq

  - by Gary McGill

  I have a table Customers with a CustomerId field, and a table of Publications with a PublicationId field. Finally, I have a mapping table CustomersPublications that records which publications a customer can access - it has two fields: CustomerId field PublicationId. For a given customer, I want to update the CustomersPublications table based on a list of publication ids. I want to remove records in CustomersPublications where the PublicationId is not in the list, and add new records where the PublicationId is in the list but not already in the table. This would be easy in SQL, but I can't figure out how to do it in Linq. For the delete part, I tried: var recordsToDelete = dataContext.CustomersPublications.Where ( cp => (cp.CustomerId == customerId) && ! publicationIds.Contains(cp.PublicationId) ); dataContext.CustomersPublications.DeleteAllOnSubmit(recordsToDelete); ... but that didn't work. I got an error: System.NotSupportedException: Method 'Boolean Contains(Int32)' has no supported translation to SQL So, I tried using Any(), as follows: var recordsToDelete = dataContext.CustomersPublications.Where ( cp => (cp.CustomerId == customerId) && ! publicationIds.Any(p => p == cp.PublicationId) ); ... and this just gives me another error: System.NotSupportedException: Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains() operator Any pointers? [I have to say, I find Linq baffling (and frustrating) for all but the simplest queries. Better error messages would help!]
