  • dynamic check_box using field_for in rails

    - by Craig Whitley
    I have a many-to-many relationship with a link box, and I want to pull those models together into one form so I can update from the same page. I'm really struggling with getting the check_box to even show all the elements of my array - I've scoured the net and been working on this literally all day, and I'm finding it difficult to apply the information I'm reading to my problem. I'm also extremely new to RoR and I've been following a bit of an outdated video tutorial (pre 2.0) so apologies for my code. So far, I've got it to output only one key pair in the array (the last one) - although outside the form, the code used in the tutorial works exactly how it should. Thats of little use though! Host is the model for which the main form is for, and Billing is the outside model that I'm trying to add to the form. This is the code that works outside of the form from the tutorial: <% for billing in @billings -%> <%= check_box_tag('billing_title[]', billing.id, @host.billings.collect {|obj| obj.id}.include?(billing.id))%> <%= billing.title %><br /> <% end -%> I just need to know how to make it work inside the form. This is the aforementioned code that only retrieves the last array keypair after looping through them: <% f.fields_for :billings do |obj| %><br /> <%= check_box_tag('billing_title[]', billing.id, @billings.collect {|obj| obj.id}.include?(billing.id))%> <%= billing.title %><br /> <% end %> The debug(@billings) : --- - !ruby/object:Billing attributes: title: Every Month id: "1" attributes_cache: {} - !ruby/object:Billing attributes: title: 12 Months id: "2" attributes_cache: {} - !ruby/object:Billing attributes: title: 6 Months id: "5" attributes_cache: {} Any help really appreciated.

  • Workflow UI Integration - is WF a good approach?

    - by AJ
    Somewhat similar to this question, except we haven't decided that we're going with WF yet. I'm working on designing a system that requires a series of decisions and activities on a "work object," so I naturally began to consider workflow, specifically WF. What I'm wondering is if WF is a good solution for a situation like the following (oversimplified for this question) case (please forgive bad ascii art): __________________ | Gather some info | | (web page) | |__________________| | | / \ / \ / \ / \ / cond \ \ 1 / \ / \ / \ / \ / | | ______________|_______________ | | | | | ______|______ ______|________ / do some / | Get more info | / process / | (web page) | /____________/ |_______________| | | / \ / \ / \ / cond. \ \ 2 / \ / \ / \ / | | |__________________ | | | | _____|_____ _____|_____ / some / / another / / process / / process / /__________/ /__________/ The part I'm struggling with is the get more info (web page) step and what happens subsequent, which would mean a halt in the execution of the workflow runtime. I'm aware that this is possible, but I'm not sure that WF is the best approach for this type of code, as the user interaction may be required at many different points through the entire workflow, and the workflow will drive what data entry screens are needed. We are using a WinForms/ASP.NET web forms package for UI, which is homegrown and difficult to push deployments on, so something like SharePoint integration is out of the question. Our back-end is DB2, and the workflow code (whether it's in WF or otherwise) will need to interact with that as well. I guess the bottom line is, should we look into using WF for this, or would we be better served just coding it ourselves? Can WF easily integrate data entry screens to capture information that can be used further on in the workflow?

  • Retrieve JSON with stackoverflow API

    - by ArtWorkAD
    Hi, I want to retrieve the information of my stackoverflow profile as JSON using the api. So I use this link http:/api.stackoverflow.com/1.0/users/401025/. But when I make the request I get a file containing the JSON data. How do I deal with that file using javascript? Here is my code (http://jsfiddle.net/hJhfU/2/): <html> <head> <script> var req; getReputation(); function getReputation(){ req = new XMLHttpRequest(); req.open('GET', 'http://api.stackoverflow.com/1.0/users/401025/'); req.onreadystatechange = processUser; req.send(); } function processUser(){ var res = JSON.parse(req.responseText); alert('test'); } </script> </head> The alert is never fired and req.responseText seems to be empty. Any ideas?

  • Connection details & timeouts in a java web service client

    - by f1sh
    Hello fellow Coders, I have to implement a webservice client to a given WSDL file. I used the SDK's 'wsimport' tool to create Java classes from the WSDL as well as a class that wrap's the webservice's only method (enhanceAddress(auth, param, address)) into a simple java method. So far, so good. The webservice is functional and returning results correcty. The code looks like this: try { EnhancedAddressList uniservResponse = getWebservicePort().enhanceAddress(m_auth, m_param, uniservAddress); //Where the Port^ is the HTTP Soap 1.2 Endpoint }catch (Throwable e) { throw new AddressValidationException("Error during uniserv webservice request.", e); } The Problem now: I need to get Information about the connection and any error that might occur in order to populate various JMX values (such as COUNT_READ_TIMEOUT, COUNT_CONNECT_TIMEOUT, ...) Unfortunately, the method does not officially throw any Exceptions, so in order to get details about a ConnectException, i need to use getCause() on the ClientTransportException that will be thrown. Even worse: I tried to test the read timeout value, but there is none. I changed the service's location in the wsdl file to post the request to a php script that simply waits forever and does not return. Guess what: The web service client does not time out but waits forever as well (I killed the app after 30+ minutes of waiting). That is not an option for my application as i eventually run out of tcp connections if some of them get 'stuck'. The enhanceAddress(auth, param, address) method is not implemented but annotated with javax.jws.* Annotations, meaning that i cannot see/change/inspect the code that is actually executed. Do i have any option but to throw the whole wsimport/javax.jsw-stuff away and implement my own soap client?

  • getting the list of all functions executed like call stack in asp.net

    - by sridhar
    Hi, I am having trouble with debugging one of the problems that I am having in our website. This is the problem. I have a webpage that contains the photo of an employee and information related to the employee. When the user logins to our website, we are storing the details of the employee in session. I am setting the image url for the photo of an employee as follows. imgEEPhoto.ImageUrl = imgPhoto.aspx?Company=XXXX&Empno=YYYY. Inside the page imgPhoto.aspx, I am checking if the session is alive for that user. when I login to the page that has the employee photo sometimes the photo is not displayed. It is because I am checking whether the session is alive inside the imgPhoto.aspx page. sometimes the session is alive and sometimes the session is not alive. It looks like there is some function that is setting the session to null asynchronously. I am not knowing how to track that function. so I am thinking that inside the imgPhoto.aspx page, if I can get the list of all functions that have been executed so far, I could track the function that is resetting the session. Is there a way to find this? If there is no another way to debug this problem, please let me know. Thanks, sridhar.

  • Python script, runs well, but not perfectly, debugging help.

    - by S1syphus
    What it does (sort of)... or is meant to, the script reads from a csv file that contains information on sound files and create a play list exactly 60 minutes long. An example csv, contains: their title, duration (in seconds), minium total time to be played (in minutes) An example is: Soundfoo,120,10 Soundbar,30,6 Sounddev,60,20 Soundrandom,15,8 The script works out the minimum instances of plays, take 'Soundfoo' for example, the length of each sample is 120 seconds and the minimum time to be played is 10 minutes, so basic maths 10*60/120 gives the number of instances the song is to be played, in this case 5. It is meant to take minimum number of instances and spread out equally from each other; so there will never be a period where for example Soundbar is played twice in a row. Then if the minium instances of each song has been used, and there is still time with in the 60 min, how is it possible to tell it to go back and fill the time by selecting each sound and including it till the 60 min is filled while remaining sparsely populated. Heres the issue(s)! The script fails to calculate the actual time require to play all the sounds in a file and the total time of the playlist, the thing is tho it doesn't get it wrong all the time maybe 3/5 times, even if I run it on the same csv file it will give me different answers. Here is the file I shall run the script on e for sake of ease to see the issue: Sound1,60,10 Sound2,60,10 Sound3,60,10 Sound4,60,10 Sound5,60,10 Sound6,60,10 I'll do it three times and post the results: 1 Required playtime in minutes: 60 Actual time in minutes to play all required ads: 62 Total playtime in minutes: 62.0 2 Required playtime in minutes: 60 Actual time in minutes to play all required ads: 71 Total playtime in minutes: 71.0 3 Required playtime in minutes: 60 Actual time in minutes to play all required ads: 60 Total playtime in minutes: 60.0 Relevant Code: pastebin.com/demkBXk6 And finally... in context: http://pastebin.com/demkBXk6 If you made it down to here, thanks for staying and reading, kudos.

  • How to assign .net membership roles to individual database records

    - by mdresser
    I'm developing a system where we want to restrict the availability of information displayed to users based on their roles. e.g. I have a tabled called EventType (ID, EventTypeDescription) which contains the following records: 1, 'Basic Event' 2, 'Intermediate Event' 3, 'Admin Event' What I need to achieve is to filter the records returned based on the username (and hence role) of the logged-in user. e.g if an advanced user is logged in they will see all the event types, if the standard user is logged in they will only see the basic event type etc. Ideally id like to do this in a way which can be easily extended to other tables as necessary. So I'd like to avoid simply adding a 'Roles' field to each table where the data is user context sensitive. One idea I'm thinking of is to create some kind of permissions table like: PermissionsTable ( ID, Aspnet_RoleId, TableName, PrimaryKeyValue ) this has the drawback of using this is obviously having to use the table name to switch which table to join onto. Edit: In the absence of any better suggestions, I'm going to go with the last idea I mentioned, but instead of having a TableName field, I'm going to normalise the TableName out to it's own table as follows: TableNames ( ID, TableName ) UserPermissionsTable ( ID, Aspnet_UserId, TableID, PrimaryKeyValue )

  • Does JAXWS client make difference between an empty collection and a null collection value as returne

    - by snowflake
    Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !

  • GAE - Getting TypeError requiring class instance be passed to class's own method...

    - by Spencer Leland
    I'm really new to programming... I set up a class to give supporting information for Google's User API user object. I store this info in the datastore using db.model. When I call the okstatus method of my user_info class using this code: elif user_info.okstatus(user): self.response.out.write("user allowed") I get this error: unbound method okstatus() must be called with user_info instance as first argument (got User instance instead) Here is my user_info class. class user_info: def auth_ctrlr(self, user): if self.status(user) == status_allowed: return ("<a href=\"%s\">Sign Out</a>)" % (users.create_login_url("/"))) else: return ("<a href=\"%s\">Sign In or Get an Account</a>)" % (users.create_logout_url("/"))) def status(self, user): match = sub_user.gql(qu_by_user_id, user.user_id) return match.string_status def group(self, user): match = sub_user.gql(qu_by_user_id, user.user_id) grp = group_names.gql(qu_by_user_id, match.groupID) return grp def okstatus(self, user): match = self.status(user) if match == status_allowed: return True My understanding is that the argument "self" inside the method's calling arguments describes it as a child to the class. I've tried everything I can think of and can't find any related info online. Can someone please tell me what I'm doing wrong? Thanks

  • Operator issues with cout

    - by BSchlinker
    I have a simple package class which is overloaded so I can output package data simply with cout << packagename. I also have two data types, name which is a string and shipping cost with a double. protected: string name; string address; double weight; double shippingcost; ostream &operator<<( ostream &output, const Package &package ) { output << "Package Information ---------------"; output << "Recipient: " << package.name << endl; output << "Shipping Cost (including any applicable fees): " << package.shippingcost; The problem is occurring with the 4th line (output << "Recipient:...). I'm receiving the error "no operator "<<" matches these operands". However, line 5 is fine. I'm guessing this has to do with the data type being a string for the package name. Any ideas?

  • Database design problem: intermediate table between 2 tables may end up with too many results.

    - by SK.
    I have to design a database to handle forms. Basically, a form needs to go through (exactly) 7 people, one by one. Each person can either agree or decline a form. If one declines, the chain stops and the following people don't even get notified that there is a form. Right now I have thought of those 3 tables: FORM, PERSON, and RESPONSE inbetween. However, my first solution sounds too heavy because each form could have up to 7 responses. Here we are with the table inbetween. That means that each successful form has 7 rows in the table RESPONSE. Here we have the responding information directly inside the form. It looks ugly but at least keeps everything as singular as possible. On the bad side I can't track the response dates, but I don't think it is crucial for that matter. What is your opinion on this? I feel like both of them are wrong and I don't know how to fix that. If that matters, I'll be using Oracle 9.

  • What's it like being a financial programmer?

    - by Mike
    As a student who's done an internship at a Silicon Valley company(non-financial), I'm curious to know what it's like working for a financial company doing software development. I'd expect the hours to be longer, and the pay to be higher. Specifically, I have the following questions: What's the work/life balance really like? Are you expected to work 80 hours a week most weeks? For those who have worked in non-financial software engineering jobs, how does being a financial software engineer compare in terms of work/life balance? How much does it pay? I'm curious as to starting(i.e. just got a BS) pay, as well as "top out" pay. (I'd prefer concrete numbers - ballpark is fine). Also, bonuses would be useful information. What jobs do financial programmers typically have? Are most just general software engineers, or do people typically have very specialized(i.e. AI or systems) backgrounds? Also, do most programmers have PhDs? Are programmers typically required to be at work, or are financial companies generally flexible about letting programmers work from home? When at work, do programmers have to dress formally? What are the technology environments like? Are finance companies using state-of-the-art hardware and software, or are they generally more conservative in upgrading their equipment? What programming languages are typically used? If VBA(shudder) is used, is it a large part of a finance company's workflow? If you could turn back the clock, would you still be a financial programmer? I'm going to keep this post open a little bit longer to get some more responses.

  • MVC: capture route url's and pass them to javascript function

    - by Tim Geerts
    Short:Is there a way to have a route-definition that will pass the "CONTROLLER/ACTION" string value to a javascript function in stead of actually going straight for the controller action? More:I have a masterpage which contains the navigation of the site. Now, all the pages need this navigation wrapped around it at all times, but because I didn't want the navigation to constantly load with each pagecall, I changed all my pages to partialviews. These partial views are loaded via the JQuery.Load() method whenever a menu item is clicked in the navigation. This all worked very good, up till now because I noticed it's also a requirement of the website to be able to link directly to page X, rather then default.aspx. So, as an example:The main page is my "default.aspx" page, this utilizes my master page with the nagivation around it. And each call to a new page uses a javascript function that loads that particular partial view inside a div that is known in my masterpage. So, the url never changes away from "default.aspx", but my content changes seemlesly. The problem is, those url's also need to be available when typed directly into the address bar. But, they're partial views, so loading them directly from the address bar makes them display without any masterpages around them. Therefore my question if it might be possible to capture the route typed into the address bar and pass that on to my javascript function that will load that route in the content div. (I hope I explained it ok enough, if not, feel free to ask more information)

  • Disassembling with python - no easy solution?

    - by Abc4599
    Hi, I'm trying to create a python script that will disassemble a binary (a Windows exe to be precise) and analyze its code. I need the ability to take a certain buffer, and extract some sort of struct containing information about the instructions in it. I've worked with libdisasm in C before, and I found it's interface quite intuitive and comfortable. The problem is, its Python interface is available only through SWIG, and I can't get it to compile properly under Windows. At the availability aspect, diStorm provides a nice out-of-the-box interface, but it provides only the Mnemonic of each instruction, and not a binary struct with enumerations defining instruction type and what not. This is quite uncomfortable for my purpose, and will require a lot of what I see as spent time wrapping the interface to make it fit my needs. I've also looked at BeaEngine, which does in fact provide the output I need, a struct with binary info concerning each instruction, but its interface is really odd and counter-intuitive, and it crashes pretty much instantly when provided with wrong arguments. The CTypes sort of ultimate-death-to-your-python crashes. So, I'd be happy to hear about other solutions, which are a little less time consuming than messing around with djgcc or mingw to make SWIGed libdisasm, or writing an OOP wrapper for diStorm. If anyone has some guidance as to how to compile SWIGed libdisasm, or better yet, a compiled binary (pyd or dll+py), I'd love to hear/have it. :) Thanks ahead.

  • Tailing 'Jobs' with Perl under mod_perl

    - by Matthew
    Hi everyone, I've got this project running under mod_perl shows some information on a host. On this page is a text box with a dropdown that allows users to ping/nslookup/traceroute the host. The output is shown in the text box like a tail -f. It works great under CGI. When the user requests a ping it would make an AJAX call to the server, where it essentially starts the ping with the output going to a temp file. Then subsequent ajax calls would 'tail' the file so that the output was updated until the ping finished. Once the job finished, the temp file would be removed. However, under mod_perl no matter what I do I can's stop it from creating zombie processes. I've tried everything, double forking, using IPC::Run etc. In the end, system calls are not encouraged under mod_perl. So my question is, maybe there's a better way to do this? Is there a CPAN module available for creating command line jobs and tailing output that will work under mod_perl? I'm just looking for some suggestions. I know I could probably create some sort of 'job' daemon that I signal with details and get updates from. It would run the commands and keep track of their status etc. But is there a simpler way? Thanks in advance.

  • cocoa - making a class like UIButton

    - by Mike
    For some reason that will take too much time to explain, I have to create a UIImageView based class that has some properties of a button. Imagine a class like the UISwitch (no I cannot base my class on the UISwitch) with two states, on and off. WHen the user selects one state, it runs a method like a button that was clicked and the method receives the sender id. I have already the class more or less working. The class is based on UIImageView. I am having difficulties to understand the following. WHen I create a new button I have a line that is like [myButton addTarget:self action:NSSelectorFromString(myMethod) forControlEvents:UIControlEventTouchUpInside]; This line defines a target and an action to run when the button is triggered. I my case I would need something like [myObject addTarget:self action:myMethod ifState:1] //or another thing ifState:2 I have no idea what kind of code I should put on the class to make this work. Remember that as a button the class should send the "sender" information to identify the object which triggered the action... Can you guys, transcendental gurus help? thanks.

  • How to write regex that searches for a dynamic amount of pairs?

    - by citronas
    Lets say a have a string such as this one: string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"bcd\";}} asd lore ipsum"; The information I want to extract "abc" and pairs like ("prop1","asd") , ("prop3", "bcd") where each pair used a ; as delimeter. Edit1: (based on MikeB's) code Ah, getting close. I found out how to parse the following: string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}} asd"; Regex r = new Regex("{{(?<single>([a-z0-9]*))\\|((?<pair>([a-z0-9]*=\"[a-z0-9.:/?=]*\";))*)}}", RegexOptions.Singleline | RegexOptions.IgnoreCase); Match m = r.Match(txt); if (m.Success) { Console.WriteLine(m.Groups["single"].Value); foreach (Capture cap in m.Groups["pair"].Captures) { Console.WriteLine(cap.Value); } } Question 1: How must I adjust the regex to say 'each value of a pair in delimited by \" only? I added chars like '.',';' etc, but I can't think of any char that I want to permit. The other way around would be much nicer. Question 2: How must I adjust this regex work with this thing here? string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}} asd lore ipsum {{aabc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}}"; Therefore I'd probably try to get groups of {{...}} and use the other regex?

  • how to verify browser IP for server-side web service

    - by Anthony
    I have a web service that needs to be able to verify the end-user's IP that called the server-script that is requesting the web service. Simple layout: Person A goes to Webpage B. Webpage B calls Web Service C to get some info on Person A. Web Service C won't give Webpage B the requested information without confirmation that the request originated from Person A's IP and not someone who has stolen Person A's session. I'm thinking that for a browser-based solution, the original site (Webpage B) can open an iframe that goes to the Web Service's authentication page. A key of some kind is passed to the browser which will some how indicate both the user's IP and Web Page B's IP, so that the Web Service can confirm that no one has nabbed anything. I have two challenges, but I'll stick to the more immediate one first: I'm not sure if my browser-based plan really makes sense. If someone steals the session cookie, how is the Web Service going to know? Would this cookie be held be Web Page B and thus be harder to steal? Is it a sound assumption that a cookie or key held by the server only and not the browser is safe? Also, would the web service, based on the iframe initial connection, be expecting the server/user-ip combo? What I mean is, does the session key provided via the iframe get stored by the web service and the Web Site B shows it has a match? Or is the session key more generic, meaning the web service is passed the key by Website B and the Web Service verifies that this is a valid session key based on what a valid session key should look like?

  • Display last picture

    - by steve
    Hi I'm inserting an image from the camera (Taking a picture) into the MediaStore.Images.Media datastore. Does anyone know how I can go about displaying the last picture taken? I used Uri image = ContentUris.withAppendedId(externalContentUri, 45); to display an image from the datastore but obviously 45 is not the correct image. I try to pass the information from the previous activity (Camera) to the display activity but I'm assuming due to the photo call back being its own thread the value never gets set. Photo code is as follows Camera.PictureCallback photoCallback = new Camera.PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub FileOutputStream fos; try { Bitmap bm = BitmapFactory.decodeByteArray(data, 0, data.length); fileUrl = MediaStore.Images.Media.insertImage(getContentResolver(), bm, "LastTaken", "Picture"); if(fileUrl == null) { Log.d("Still", "Image Insert Failed"); return; } else { picUri = Uri.parse(fileUrl); sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, picUri)); } } catch(Exception e) { Log.d("Picture", "Error Picture: ", e); } camera.startPreview(); } };

  • PHP sessions causing Apache to hang indefinitely

    - by Kmaid
    The problem is that every so often a page that writes to a Session will cause apache to hang forever for a particular session. Once this error occurs for one user any further modifications to any session of any user will cause the website to hang for this user. This problem has been my sole focus for days. I have a development VPS running Windows 2003 and default latest version of XAMPP using the standard PHP session handler. The code in question actually runs on two other machines perfectly normally so although my common sense says it’s a web server configuration issue but at this point I am willing to try anything. On further investigation there are no errors in the Apache, PHP or System event log. Resources are abundant and there is no “AJAX shit storm” or more than a couple writes to a session per page. I have also implemented session_write_close() wherever possible to try and help elevate the problem. I have checked the session’s directory which is set to “C:\windows\Temp” and found that once a user enters this hanging phase that the corresponding session file is exclusively locked and the only way to resolve this is to stop Apache and wait a few moments for the files to become unlocked and delete them. I am not wondering if deletion is required. The Sessions themselves only contain 4 bits of information. ShoppingCartID, UserID, UserLevel and Refering URL and are alphanumerical with an occasional slash. My PHP.INI’s session section is configured like this: session.save_handler = files session.save_path = "C:\WINDOWS\Temp" session.use_cookies = 1 session.name = PHPSESSID session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.cookie_httponly = session.serialize_handler = php session.gc_probability = 1 session.gc_divisor = 100 session.gc_maxlifetime = 1440 session.bug_compat_42 = 1 session.bug_compat_warn = 1 session.referer_check = session.entropy_length = 0 session.entropy_file = session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 0 session.hash_function = 0 session.hash_bits_per_character = 4 I have tried everything I can think of and the whole problem is now a blur to me. Any ideas would be appreciated and thanks for your time reading this :)

  • MVC UI with Mock Controllers?

    - by Jaimal Chohan
    I'm working with Aspnet MVC 2 (R2) and at the same time playing about with the whole alt.net stack. One of this things I would like to be able todo is basically write my Views, and be able to interact with them without having to write the controller logic. E.g. I have a view that displays a list of orders and I can click on an order which redirects to another view where I can edit it, but I don't want to get into the nitty gritty of writing the code to actually get a list of orders, or update an existing ordes. I want to do so I can write UI tests in WaitN/AOT/Selenium without having to worry about whats happening underneath, and also It would help drive my controller logic on a need basis as opposed to guess work based of of the supplied screenshots How do you guys accomplish this atm? Can you provide links ot useful blog posts/tools/framework/articles with information on how to accomplish this p.s. I primarly use Rhino Mocks & NUnit but can happliy change to other tools if they support the above better.

  • weighted matching algorithm in Perl

    - by srk
    Problem : We have equal number of men and women.each men has a preference score toward each woman. So do the woman for each man. each of the men and women have certain interests. Based on the interest we calculate the preference scores. So initially we have an input in a file having x columns. First column is the person(men/woman) id. id are nothing but 0.. n numbers.(first half are men and next half woman) the remaining x-1 columns will have the interests. these are integers too. now using this n by x-1 matrix... we have come up with a n by n/2 matrix. the new matrix has all men and woman as their rows and scores for opposite sex in columns. We have to sort the scores in descending order, also we need to know the id of person related to the scores after sorting. So here i wanted to use hash table. once we get the scores we need to make up pairs.. for which we need to follow some rules. My trouble is with the second matrix of n by n/2 that needs to give information of which man/woman has how much preference on a woman/man. I need these scores sorted so that i know who is the first preferred woman/man, 2nd preferred and so on for a man/woman. I hope to get good suggestions on the data structures i use.. I prefer php or perl. Thank you in advance
