• Assignment to None

  - by Joel

  Hello, I have a function which returns 3 numbers, e.g.: def numbers(): return 1,2,3 usually I call this function to receive all three returned numbers e.g.: a,b,c=numbers() However, I have one case in which I only need the first returned number. I tried using: a, None None = numbers() But I receive "SyntaxError: assignment to None". I know, of course, that i can use the first option I mentioned and then not use "b" and "c", but only "a". However, this seems like a "waste" of two vars and feels like wrong programming. Any ideas? Thanks, Joek

• DirectoryIndex not working because of mod_rewrite?

  - by Kjensen

  Requests to www.domainname.com and domainname.com should display index.html, not index.php as it does now. This is the .htaccess file: # -FrontPage- IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti* # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On # RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress I tried adding a DirectoryIndex index.html to the file, but that did not work. I suspect that has something to do with the mod_rewrite stuff, but being an apache-n00b I am really just grasping for straws. Can I add a rewriterule, or what should I do?

• How to get debugging of an App Engine application working?

  - by Chris Lacy

  I've got 10+ years in C/C++, and it appears Visual Studio has spoilt me during that time. In Visual Studio, debbuging issimple: I just add a breakpoint to a line of code, and as soon as that code is executed, my breakpoint triggers, at which point I can view a callstack, local/member variables, etc. I'm trying to achieve this functionality under App Engine. I assume that is possible? All the searching I've done to this point has led me to using Pydev in Eclipse. As best I can tell, I am successfully launching my simple 'hello world' program in Debug mode. But the IDE doesn't even seem to have an option to set a breakpoint? I must be missing something. I've googled long and hard about this, but am having no luck. Most results trace back to the same old threads that don't deal directly with my issue. Can anyone shed some light on how you get basic debugging setup using Pydev/Eclipse with App Engine? Alternatively, if there's an easier way to debug App Engine than using Pydev/Eclipse, I'd love to hear about it. Thanks in advance.

• How do i use repoze.who?

  - by misterwebz

  I'm having some trouble understanding how repoze.who works. I've followed a tutorial i found by searching on google and here's what i already have: This is what i added in my middleware.py file from repoze.who.config import make_middleware_with_config as make_who_with_config app = make_who_with_config(app, global_conf, app_conf['who.config_file'], app_conf['who.log_file'], app_conf['who.log_level']) Here's the who.ini : http://pastebin.com/w5Tba2Fp Here's repoze_auth.py in /lib/auth/: from paste.httpexceptions import HTTPFound from iwant.model import User class UserModelPlugin(object): def authenticate(self, environ, identity): try: username = identity['login'] password = identity['password'] except KeyError: return None success = User.authenticate(username, password) return success def add_metadata(self, environ, identity): username = identity.get('repoze.who.userid') user = User.get(username) if user is not None: identity['user'] = user I've also checked the plugins in the repoze.who folder, but i failed to understand how it's supposed to be used. I'd appreciate it if someone would push me in the right direction.

• Apache - "dynamic" rewrite rule

  - by Christian A. Rasmussen

  Hi there. I'm working on a Zend Framework project where I've stumbled across a bit of a problem. The problem originates from the fact that modules are 2nd class citizens in Zend Framework. In my project, I'd like for each module to have a folder containing files which are to be accessed from the outside - files such as stylesheets, javascripts and images. Now, how is this to be done. With a Zend Framework project I have a folder structure which looks like this: application/ modules/ moduleOne/ public/ stylesheet.css moduleTwo/ moduleThree/ public/ index.php The standard .htaccess file located in the public/ folder holds this: SetEnv APPLICATION_ENV development RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] The way it works, is that the project's apache DocumentRoot is the public/ folder. All requests gets redirected through the index.php file where Zend Framework's router component takes over. Now, I'm by no means an expert with Apache nor mod_rewrite so pardon me if this is just silly. I imagine that I implement an extra step in the existing rewrite rule so that if I request http://project/public/moduleOne/stylesheet.css it will for instance resolve to /var/www/project/application/modules/moduleOne/public/stylesheet.css. So the steps which need to be done is to check if the first element in the URI is public/ if it is, we take the next segment as the modules name and use that in the path we're trying to resolve to and attempt to serve the file. Is this at all possible or does anyone have a better suggestion? Thank you for your time Christian Rasmussen

• Group Chat XMPP with Google App Engine

  - by David Shellabarger

  Google App Engine has a great XMPP service built in. One of the few limitations it has is that it doesn't support receiving messages from a group chat. That's the one thing I want to do with it. :( Can I run a 3rd party XMPP/Jabber server on App Engine that supports group chat? If so, which one?

• Convert or strip out "illegal" Unicode characters

  - by Oli

  I've got a database in MSSQL that I'm porting to SQLite/Django. I'm using pymssql to connect to the database and save a text field to the local SQLite database. However for some characters, it explodes. I get complaints like this: UnicodeDecodeError: 'ascii' codec can't decode byte 0x97 in position 1916: ordinal not in range(128) Is there some way I can convert the chars to proper unicode versions? Or strip them out?

• JSON serialization of Google App Engine models

  - by user111677

  I've been search for quite a while with no success. My project isn't using Django, is there a simple way to serialize App Engine models (google.appengine.ext.db.Model) into JSON or do I need to write my own serializer? My model class is fairly simple. For instance: class Photo(db.Model): filename = db.StringProperty() title = db.StringProperty() description = db.StringProperty(multiline=True) date_taken = db.DateTimeProperty() date_uploaded = db.DateTimeProperty(auto_now_add=True) album = db.ReferenceProperty(Album, collection_name='photo') Thanks in advance.

• Good way to edit the previous defined class in ipython

  - by leo

  Hi, I am wondering a good way to follow if i would like to redefine the members of a previous defined class in ipython. say : I have defined a class intro like below, and later i want to redefine part of the function definition _print_api. Any way to do that without retyping it . class intro(object): def _print_api(self,obj): def _print(key): if key.startswith('_'): return '' value = getattr(obj,key) if not hasattr(value,im_func): doc = type(valuee).__name__ else: if value.__doc__ is None: doc = 'no docstring' else: doc = value.__doc__ return ' %s :%s' %(key,doc) res = [_print(element) for element in dir(obj)] return '\n'.join([element for element in res if element != '']) def __get__(self,instance,klass): if instance is not None: return self._print(instance) else: return self._print_api(klass)

• Does mod_php honor HEAD requests properly?

  - by rkulla

  The HTTP/1.1 RFC stipulates "The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response." I know Apache honors the RFC but modules don't have to. My question is, does mod_php5 honor this? The reason I ask is because I just came across an article saying that PHP developers should check this themselves with: if (stripos($_SERVER['REQUEST_METHOD'], 'HEAD') !== FALSE) { exit(); } but seeing as how browsers send HEAD requests for cache checking it seems unlikely to me that no book, docs, etc., advise PHP developers to do this check. I googled a second and not much turned up, other than some people saying they try to strange things like mod_rewrite/redirect after getting HEAD requests and some old bug ticket from like 2002 claiming that mod_php still executed the rest of the script by default. So I just ran a quick test by using PECL::HTTP to run http_head('http://mysite.com/test-head-request.php'); while having: <?php error_log('REST OF SCRIPT STILL RAN'); ?> in test-head-request.php to see if the rest of the script still executed, and it didn't. I figure that should be enough to settle it, but want to get more feedback and maybe help clear up confusion for anyone else who has wondered about this. So if anyone knows off the top of their head (no pun intended) - or have any conventions they use for receiving HEAD requests, that'd be great. Otherwise, I'll grep the C source later and respond in a comment with my findings. Thanks.

• Apache Rewrite - put parts of query string in replacement string

  - by Rangi Robinson

  Hello, I'd like to rewrite: www.example.com/file.html?username=john&number=1234 To: www.example.com/users/john But I can't figure out how to extract the "username" value from the query string. I've been Googling this all morning and reading the official docs but no luck. I need to solve this problem with a rewrite, rather than changing the application. Any help much appreciated! Rangi

• Display additional data while iterating over a Django formset

  - by Jannis

  Hi, I have a list of soccer matches for which I'd like to display forms. The list comes from a remote source. matches = ["A vs. B", "C vs. D", "E vs, F"] matchFormset = formset_factory(MatchForm,extra=len(matches)) formset = MatchFormset() On the template side, I would like to display the formset with the according title (i.e. "A vs. B"). {% for form in formset.forms %} <fieldset> <legend>{{TITLE}}</legend> {{form.team1}} : {{form.team2}} </fieldset> {% endfor %} Now how do I get TITLE to contain the right title for the current form? Or asked in a different way: how do I iterate over matches with the same index as the iteration over formset.forms? Thanks for your input!

• Is it bad practice to extend the MongoEngine User document?

  - by Soviut

  I'm integrating MongoDB using MongoEngine. It provides auth and session support that a standard pymongo setup would lack. In regular django auth, it's considered bad practice to extend the User model since there's no guarantee it will be used correctly everywhere. Is this the case with mongoengine.django.auth? If it is considered bad practice, what is the best way to attach a separate user profile? Django has mechanisms for specifying an AUTH_PROFILE_MODULE. Is this supported in MongoEngine as well, or should I be manually doing the lookup?

• Server authorization with MD5 and SQL.

  - by Charles

  I currently have a SQL database of passwords stored in MD5. The server needs to generate a unique key, then sends to the client. In the client, it will use the key as a salt then hash together with the password and send back to the server. The only problem is that the the SQL DB has the passwords in MD5 already. Therefore for this to work, I would have to MD5 the password client side, then MD5 it again with the salt. Am I doing this wrong, because it doesn't seem like a proper solution. Any information is appreciated.

• Displaying Google Calendar event data on FullCalendar

  - by aurealus

  I am using Google Calendar as a storage engine for a calendar system I am building, however, I am using a single Google user account with multiple calendars, i.e. each user on my system has their own calendar within the one user account. I'm able to create a calendar per user just fine, but I would like to have FullCalendar retrieve the events for display purposes, without manually getting the magic cookie url from Google Calendar settings. I would like to be able to retrieve it programmatically or 'proxy' the feed via an authenticated call to get event data that I'm doing in Django. $('#calendar').fullCalendar({ events: $.fullCalendar.gcalFeed( "http://www.google.com/calendar_url/" <-- or /my/event/feed/url ) });

• Rails Beta3 & PaperClip & Passenger Bundler::PathError

  - by firecall

  So I'm going around in circles with this - I'm using a fork of the Paperclip Rails gem to get it to work with Rails3. Works fine on my OSX box with Passenger. But on my server (CentOS 5) I get this this error: git://github.com/lmumar/paperclip.git (at rails3) is not checked out. Please runbundle install(Bundler::PathError)Blockquote I tried Bundle Pack, but that doesnt pack gems from github. I read a post about setting the parh to the BUNDLE_HOME in my application.rb file which I tried: ENV['BUNDLER_HOME']="~/.bundle/ruby/1.8/bundler/gems/" But that doesnt work. Any ideas anyone? I dont know what else to do and have no idea how to debug or trace the problem further :( Passenger version 2.2.11. thanks.

• How's my pygame code?

  - by Isaiah

  I'm still getting the hang of lots of things and thought I should post some code I made with pygame and get some feedback^^. I posted code here: http://urlvars.com/code/snippet/39272/my-bouncing-program http://urlvars.com/code/snippet/39273/my-bouncing-program-classes There's tome things that I implemented that I'm not using yet I just realized like a timer at the bottom of the main while loop. If my code isn't readable, I'm sorry, I'm self taught and this is the first code I've ever posted anywhere. By the way I made some variables that take the screensize and half it to find a point to spit out the squares, but when I try to use it, it makes a weird effect :/ Try switching the list i have in the newbyte() function with the halfScreen variable and see it freak out o.O thank you

• Django: How to create a model dynamically just for testing

  - by muhuk

  I have a Django app that requires a settings attribute in the form of: RELATED_MODELS = ('appname1.modelname1.attribute1', 'appname1.modelname2.attribute2', 'appname2.modelname3.attribute3', ...) Then hooks their post_save signal to update some other fixed model depending on the attributeN defined. I would like to test this behaviour and tests should work even if this app is the only one in the project (except for its own dependencies, no other wrapper app need to be installed). How can I create and attach/register/activate mock models just for the test database? (or is it possible at all?) Solutions that allow me to use test fixtures would be great.
