• Symfony 1.4 filter on index page

  - by Imran Azad

  I'm trying to apply a filter to the index page of my module, the code works as I've tested it on another page called filter within the same module. The problem I'm having is that on submitting the filter on the index page (form action points to index) Symfony instead decides to route to the create action for some reason. Although the create method isn't visible in the URL a new form is instantiated on the index page which leads me to suspect it is routing to the create action: http://locahost.com/frontend_dev.php/mymodule Any ideas how I can get a filter to work on the index page?

• how to send parameters to a web Services via SOAP?

  - by Alejandra Meraz

  Before I start: I'm programming for Iphone, using objective C. I have already implemented a call to a web service function using NSURLRequest and NSURLConnection and SOAP. The function then returns a XML with the info I need. The code is as follows: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body>\n" "<function xmlns=\"http://tempuri.org/\" />\n" "</soap:Body>\n" "</soap:Envelope>\n"]; NSURL *url = [NSURL URLWithString:@"http://myHost.com/myWebService/service.asmx"]; //the url to the WSDL NsMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]]; [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Lenght"]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:@"myhost.com" forHTTPHeaderField:@"Host"]; [theRequest addValue:@"http://tempuri.org/function" forHTTPHeaderField:@"SOAPAction"]; [theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; I basically copy and modified the soap request the web service gave as an example. i also implemented the methods didRecieveResponse didRecieveAuthenticationChallenge didRecievedData didFailWithError connectionDidFinishLoading. And it works perfectly. Now I need to send 2 parameters to the function: "location" and "module". I tried modifying the soapMessage like this: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body xmlns=\"http://tempuri.org/\" />\n" "<m:GetMonitorList>\n" "<m:location>USA</m:location>\n" "<m:module>DEVELOPMENT</m:module>\n" "</m:GetMonitorList>\n" "</soap:Body>\n" "</soap:Envelope>\n"]; But is not working...any thoughts how should I modify it? Extra info: it seems to be working... kind of. But the webservice return nothing. During the connection, the method didReceiveResponse execute once and the didFinishLoading method executes as well. But not even once the method didReceiveData. I wonder if, even though there is no USA locations, it will still send at least something? is there a way to know which are the parameters the function is waiting for? I don't have access to the source of the webservice but i can access the WSDL.

• Python: User-Defined Exception That Proves The Rule

  - by bandana

  Python documentations states: Exceptions should typically be derived from the Exception class, either directly or indirectly. the word 'typically' leaves me in an ambiguous state. consider the code: class good(Exception): pass class bad(object): pass Heaven = good() Hell = bad() >>> raise Heaven Traceback (most recent call last): File "<pyshell#163>", line 1, in <module> raise Heaven good >>> raise Hell Traceback (most recent call last): File "<pyshell#171>", line 1, in <module> raise Hell TypeError: exceptions must be classes or instances, not bad so when reading the python docs, should i change 'typically' with ''? what if i have a class hierarchy that has nothing to do with the Exception class, and i want to 'raise' objects belonging to the hierarchy? i can always raise an exception with an argument: raise Exception, Hell This seems slightly awkward to me What's so special about the Exception class, that only its family members can be raised?

• Dynamically loading JavaScript synchronously

  - by spoon16

  I'm using the module pattern, one of the things I want to do is dynamically include an external JavaScript file, execute the file, and then use the functions/variables in the file in the return { } of my module. I can't figure out how to do this easily. Are there any standard ways of performing a pseudo synchronous external script load? function myModule() { var tag = document.createElement("script"); tag.type = "text/javascript"; tag.src = "http://some/script.js"; document.getElementsByTagName('head')[0].appendChild(tag); //something should go here to ensure file is loaded before return is executed return { external: externalVariable } }

• Why are closures broken within exec?

  - by Devin Jeanpierre

  In Python 2.6, >>> exec "print (lambda: a)()" in dict(a=2), {} 2 >>> exec "print (lambda: a)()" in globals(), {'a': 2} Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 1, in <module> File "<string>", line 1, in <lambda> NameError: global name 'a' is not defined >>> exec "print (lambda: a).__closure__" in globals(), {'a': 2} None I expected it to print 2 twice, and then print a tuple with a single cell. It is the same situation in 3.1. What's going on?

• JPA Database strcture for internationalisation

  - by IrishDubGuy

  I am trying to get a JPA implementation of a simple approach to internationalisation. I want to have a table of translated strings that I can reference in multiple fields in multiple tables. So all text occurrences in all tables will be replaced by a reference to the translated strings table. In combination with a language id, this would give a unique row in the translated strings table for that particular field. For example, consider a schema that has entities Course and Module as follows :- Course int course_id, int name, int description Module int module_id, int name The course.name, course.description and module.name are all referencing the id field of the translated strings table :- TranslatedString int id, String lang, String content That all seems simple enough. I get one table for all strings that could be internationalised and that table is used across all the other tables. How might I do this in JPA, using eclipselink 2.4? I've looked at embedded ElementCollection, ala this... JPA 2.0: Mapping a Map - it isn't exactly what i'm after cos it looks like it is relating the translated strings table to the pk of the owning table. This means I can only have one translatable string field per entity (unless I add new join columns into the translatable strings table, which defeats the point, its the opposite of what I am trying to do). I'm also not clear on how this would work across entites, presumably the id of each entity would have to use a database wide sequence to ensure uniqueness of the translatable strings table. BTW, I tried the example as laid out in that link and it didn't work for me - as soon as the entity had a localizedString map added, persisting it caused the client side to bomb but no obvious error on the server side and nothing persisted in the DB :S I been around the houses on this about 9 hours so far, I've looked at this Internationalization with Hibernate which appears to be trying to do the same thing as the link above (without the table definitions it hard to see what he achieved). Any help would be gratefully achieved at this point... Edit 1 - re AMS anwser below, I'm not sure that really addresses the issue. In his example it leaves the storing of the description text to some other process. The idea of this type of approach is that the entity object takes the text and locale and this (somehow!) ends up in the translatable strings table. In the first link I gave, the guy is attempting to do this by using an embedded map, which I feel is the right approach. His way though has two issues - one it doesn't seem to work! and two if it did work, it is storing the FK in the embedded table instead of the other way round (I think, I can't get it to run so I can't see exactly how it persists). I suspect the correct approach ends up with a map reference in place of each text that needs translating (the map being locale-content), but I can't see how to do this in a way that allows for multiple maps in one entity (without having corresponding multiple columns in the translatable strings table)...

• How can I intercept Drupal User Registration after it has passed all validations?

  - by Senthil

  Hi, I am using Drupal 6.16 In the user registration module, I want to hook in AFTER all validations have been made and the row is about to be inserted. Here, I want to run my business logic. If my business logic fails, the drupal registration should be stopped. I can do this by setting an error in the form. If it succeeds, drupal registration SHOULD proceed and complete. I decided to use the validate operation in hook_user. But it is possible for drupal registration to be stopped at the validation phase itself, by some other module that is run after mine. What I want is, when my business logic succeeds, the drupal registration MUST succeed. Which hook and operation should I use so that I can intercept just before the drupal user info insert/update and after all validations have succeeded?

• What is the best approach to manipulate assets in Drupal from .Net application?

  - by Amandeep Singh

  I'm beginning work on a project that will access a Drupal site to create nodes on the site. This includes file uploading, as the project is to allow people to upload pictures en mass to a Drupal site with minimal ado. Note that my application is written in .Net. What I would like to know is the best approach to achieve the same? Based on initial research it looks like there are several options: 1. XML-RPC 2. Custom PHP module deployed in drupal. But, what is the way to invoke it from .Net? 3. Use a cron job to pick up the files from a watch folder. And add a cron_hook in my module to deploy the file.

• Why can't I start XML entity names with 'xml''?

  - by flamey

  <XmlInfo /> I ran into problem using Perl's popular SOAP::Lite module, where it wouldn't accept XML entity names starting with "xml" (regardles letters' case). The author of the module replied to email saying that entity names starting with "xml" are not permitted in XML specification, but I couldn't find it in W3C's documents for 1.0 and 1.1 specs, I also couldn't find it in any of the articles or guidelines docs about XML entity naming. In fact some guideline documents used names starting with xml as an example, and lots of people are using it, as I see via Google Code Search. So are there any restrictions (besides which characters to use as defined in W3C's documents) in Entity naming in XML? Is there a restriction saying you can't name entities starting with "xml"?

• Thinking about introducing PHP/MySQL into a .NET/SQL Server environment. Thoughts?

  - by abszero

  I posted this over at reddit but it didn't gain any momentum. So here is what is going on: our company was recently purchased by another web shop and I was promoted to head of development here in our office. Our office is completely .NET/SQL Server and the company who purchased us is a *nix/PHP/MySQL shop. Now several of our large clients who are on the .NET platform are up for complete rewrites (the sites are from '04 and are running on the 1.x framework.) While reviewing the proposal for one client with my superior I came across a pretty extensive module which would require several hundred man hours to complete and voiced some concern about it in relation to the quote. One of the guys from the PHP group happen to hear this and told me of a module that they (PHP Group) use in Drupal that does exactly what the proposal in front of me was describing and it only took, at most, 8 hours to completely setup / configure. My superior suggested that I take a look at Drupal and the module in question over the weekend but stressed that we should only go that route if it really made sense. So this weekend I spun up a CentOS instance in VirtualBox and started playing around with Drupal. I am still fleshing it out so don't have a solid opinion on it just yet. Anyway I have some questions / fears that I was hoping progit could help me out in! Has anyone had experience doing this and, if so, how did it turn out? I am completely ignorant to what IDE's (if any) are available to for PHP. The last time I worked with PHP it was in Notepad and that was less than intuitive. So is there are more intuitive IDE out there for PHP dev? I don't want to scare my .NET guys. Since the merger all of our new business clients that have had relatively small websites have gone on Drupal with the larger sites going on .NET. My concern is that if they see a large site go onto Drupal that they might start getting anxious and start handing out their resumes. For the foreseeable future there are no plans to liquidate the .NET platform and really we can't just from a support standpoint. What would be the best way to approach this? Any other helpful info? Thanks!

• What is annotations and how do it actually works for frameworks like Spring ?

  - by Rachel

  I am new to Spring and now a days I hear a lot about Spring Framework. I have two sets of very specific questions: Set No. 1: What are annotations in general ? How does annotations works specifically with Spring framework ? Can annotations be used outside Spring Framework or are they Framework specific ? Set No. 2: What module of Spring Framework is widely used in Industry ? I think it is Spring MVC but why it is the most used module, if am correct or correct me on this ? I am newbie to Spring and so feel free to edit this questions to make more sense.

• Communicate multiple times with a process without breaking the pipe?

  - by Manux

  Hello, it's not the first time I'm having this problem and its really bugging me. Whenever I open a pipe using the Python subprocess module, I can only communicate with it once, as the documentation specifies: Read data from stdout and stderr, until end-of-file is reached proc = sub.Popen("psql -h darwin -d main_db".split(),stdin=sub.PIPE,stdout=sub.PIPE) print proc.communicate("select a,b,result from experiment_1412;\n")[0] print proc.communicate("select theta,zeta,result from experiment_2099\n")[0] The problem here is that the second time, Python isn't happy. Indeed, he decided to close the file after the first communicate: Traceback (most recent call last): File "a.py", line 30, in <module> print proc.communicate("select theta,zeta,result from experiment_2099\n")[0] File "/usr/lib64/python2.5/subprocess.py", line 667, in communicate return self._communicate(input) File "/usr/lib64/python2.5/subprocess.py", line 1124, in _communicate self.stdin.flush() ValueError: I/O operation on closed file So... multiple communications aren't allowed? I hope not ;) Please enlighten me.

• Drupal : Custom views filter

  - by Joseph

  Hi, First thing I would say is that I am a Drupal newbie. So, I would appreciate your answer in a detailed step by step process. I am using Drupal 6 and location module. There are two main content types - user profile (using content profile module) and event content type. Both have one field for location. Now, lets suppose in his profile, user is selecting city as Toronto and province as Ontario. And some events have been added for Toronto city. I need one Views, which will display events from user city. So, if user is from Vancouver, and they click on "my city events", they will see list of events from their city. Someone told me that I can achieve this using arguments/ relationships, but I don't know how to do that. Can someone please help me out? I am not good at PHP either :(

• LXC Container Networking

  - by digitaladdictions

  I just started to experiment with LXC containers. I was able to create a container and start it up but I cannot get dhcp to assign the container an IP address. If I assign a static address the container can ping the host IP but not outside the host IP. The host is CentOS 6.5 and the guest is Ubuntu 14.04LTS. I used the template downloaded by lxc-create -t download -n cn-01 command. If I am trying to get an IP address on the same subnet as the host I don't believe I should need the IP tables rule for masquerading but I added it anyways. Same with IP forwarding. I compiled LXC by hand from the following source https://linuxcontainers.org/downloads/lxc-1.0.4.tar.gz Host Operating System Version #> cat /etc/redhat-release CentOS release 6.5 (Final) #> uname -a Linux localhost.localdomain 2.6.32-431.20.3.el6.x86_64 #1 SMP Thu Jun 19 21:14:45 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Container Config #> cat /usr/local/var/lib/lxc/cn-01/config # Template used to create this container: /usr/local/share/lxc/templates/lxc-download # Parameters passed to the template: # For additional config options, please look at lxc.container.conf(5) # Distribution configuration lxc.include = /usr/local/share/lxc/config/ubuntu.common.conf lxc.arch = x86_64 # Container specific configuration lxc.rootfs = /usr/local/var/lib/lxc/cn-01/rootfs lxc.utsname = cn-01 # Network configuration lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 LXC default.confu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:12:30:f2 brd ff:ff:ff:ff:f #> cat /usr/local/etc/lxc/default.conf lxc.network.type = veth lxc.network.link = br0 lxc.network.flags = up #> lxc-checkconfig Kernel configuration not found at /proc/config.gz; searching...

• Getting a PasteScript error when I try to serve an existing Pylons app.

  I'm trying to serve an existing Python 2.5 Pylons application on OS X Snow Leopard. I've already installed Python 2.5 and set it as the default Python installation, installed paster, and installed the version of Pylons the app needs (0.9.6.1) as well as other eggs... but when I cd to the main folder and do "paster serve development.ini" I get the following: File "/usr/local/bin/paster", line 5, in <module> from pkg_resources import load_entry_point File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py", line 2603, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py", line 666, in require File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py", line 565, in resolve pkg_resources.DistributionNotFound: PasteScript==1.7.3 I definitely have done "easy_install PasteScript==1.7.3" and I still get this error.

• Is there a cap on the number of modules WinDbg can see?

  - by Bethor

  Does anyone know if there is a cap on the number of DLLs WinDbg can see ? I believe Visual Studio was once capped at 500 but I can't find a source for this claim outside of some second hand accounts at work. I'm trying to debug a hairy scenario and WinDbg's stack trace is incomplete. According to Process Explorer, the module I'm interested in is loaded but it doesn't show up in the output of 'lm' in WinDbg. Suspiciously, said output is exactly 500 modules long, even though I know there are many more than that loaded, leading me to believe WinDbg isn't seeing DLLs beyond the first 500. Can anyone confirm ? Or suggest some other reason why a loaded module might not show up in 'lm' ?

• Rails 3 routes and using GET to create clean URLs?

  - by Hard-Boiled Wonderland

  I am a little confused with the routes in Rails 3 as I am just starting to learn the language. I have a form generated here: <%= form_tag towns_path, :method => "get" do %> <%= label_tag :name, "Search for:" %> <%= text_field_tag :name, params[:name] %> <%= submit_tag "Search" %> <% end %> Then in my routes: get "towns/autocomplete_town_name" get "home/autocomplete_town_name" match 'towns' => 'towns#index' match 'towns/:name' => 'towns#index' resources :towns, :module => "town" resources :businesses, :module => "business" root :to => "home#index" So why when submitting the form do I get the URL: /towns?utf8=?&name=townname&commit=Search So the question is how do I make that url into a clean url like: /towns/townname Thanks, Andrew

• [PRISM2] Added view does not appear on screen

  - by Jeaffrey Gilbert

  Why my "mainRegion.Activate(view);" doesn't display the view on screen? It only works if I remove the default view that registered (RegisterViewWithRegion) in ModuleInit.cs though I don't put .Activate() after I added a View. But a problem occurs if I move to other module, and get back to module which default view has been removed, I get blank page. Any clues? Thank you. *) I prefer not to remove default view, but only with Activate(view) can show the View I want as explained in my reference. reference: http://msdn.microsoft.com/en-us/library/dd458899.aspx

• Calling gwt static method from parent of iframe

  - by Richard Wallis

  I'd like to know how to call a GWT static method from the parent of the iframe in which the gwt module is loaded. As a simple example suppose I have the following gwt class: public class Simple { public static void showWindow() { Window.alert("Hello from the iframe"); } } I create an html host page called "iFrameHost.html" that can run the function above.
