  • Wrong sessionID being used in callback, but only on one particular computer

    - by user210119
    I am writing a Python/Django web application that uses OAuth (for the TwitterAPI, not that it should matter). I am storing a session ID in my login function, and then after using OAuth to get the user's token, I try to retrieve the sessionID in my callback function. The callback function then always fails(throws an exception) because it can't find the OAuth token in the session. Through the debugger, I am able to determine that the session ID that the server is using is incorrect - it does not match the session ID that was stored in the login function. It's therefore unsurprising that the Oauth tokens were not there. The session that appears in the callback was the same one each time (until I tried deleting it - see "things I've tried below"), and it started out as an old session, with some data in it that is from a different django app running on the same server that I hadn't touched in a couple weeks. Here's the kicker: everything I described is an issue only on our production server, and only when connecting to it from my computer. Let me clarify: this only happens with my particular laptop. I can connect to the app just fine from someone else's computer. Other people cannot connect with their accounts on my computer. Furthmore, I can connect just fine to the app when it is running on my localhost using the built-in django webserver, just not to the production server. My setup: my server and local box are running= Django 1.2.0 and Python 2.6.5. My local box is running Snow Leopard and the Django webserver, the server is running Ubuntu, Apache2, and mod-wsgi. For sessions, I am using Django's default session backend (DB). Things I have tried, all to no avail: logging in with a different account, including new accounts that have never OAuthed to this app before Clearing cookies, using incognito mode, using a different web browser on my same computer. Each time, upon inspecting my cookies, the sessionID matched the sessionID in the login function and was different from the sessionID in the callback. deleting the session in the database that appears in the callback function, (the one that appeared to be old data). The callback function still fails, and the sessionID it appears to be using is now a new one using a different session backend (DB-cache, flat file, etc...) restarting the server, my computer, etc. My first question on StackOverflow, so bear with me if I didn't quite follow local conventions. I am just at a loss as to what to even look for - what are the things that could possibly be causing sessions to not work on my particular computer, and (so far!) only my particular computer?

  • Why is django admin not accepting Nullable foreign keys?

    - by p.g.l.hall
    Here is a simplified version of one of my models: class ImportRule(models.Model): feed = models.ForeignKey(Feed) name = models.CharField(max_length=255) feed_provider_category = models.ForeignKey(FeedProviderCategory, null=True) target_subcategories = models.ManyToManyField(Subcategory) This class manages a rule for importing a list of items from a feed into the database. The admin system won't let me add an ImportRule without selecting a feed_provider_category despite it being declared in the model as nullable. The database (SQLite at the moment) even checks out ok: >>> .schema ... CREATE TABLE "someapp_importrule" ( "id" integer NOT NULL PRIMARY KEY, "feed_id" integer NOT NULL REFERENCES "someapp_feed" ("id"), "name" varchar(255) NOT NULL, "feed_provider_category_id" integer REFERENCES "someapp_feedprovidercategory" ("id"), ); ... I can create the object in the python shell easily enough: f = Feed.objects.get(pk=1) i = ImportRule(name='test', feed=f) i.save() ...but the admin system won't let me edit it, of course. How can I get the admin to let me edit/create objects without specifying that foreign key?

  • How do I use django settings in my logging.ini file?

    - by slypete
    I have a BASE_DIR setting in my settings.py file: BASE_DIR = os.path.dirname(os.path.abspath(__file__)) I need to use this variable in my logging.ini file to setup my file handler paths. The initialization of logging happens in the same file, the settings.py file, below my BASE_DIR variable: LOG_INIT_DONE=False if not LOG_INIT_DONE: logging.config.fileConfig(LOGGING_INI) LOG_INIT_DONE=True Thanks, Pete

    class LocationLog(models.Model): user = models.ForeignKey(User) utm = models.GeometryField(spatial_index=True) This is my database model. I would like to insert a row. I want to insert a circle at point -55, 333. With a radius of 10. How can I put this circle into the geometry field? Of course, then I would want to check which circles overlap a given circle.

  • Is it hacky to manually construct JSON and manually handle GET, POST instead of using a proper RESTful API for AJAX functionality?

    - by kliao
    I started building a Django app, but this probably applies to other frameworks as well. In Backbone.js methods that call the server (fetch(), create(), destroy(), etc.), should you be using a proper RESTful API such as one provided by Tastypie or Django-Piston? I've founded it easier and more flexible to just construct the JSON in my Django Views, which are mapped to some URLs that Backbone.js can use. Then again, I'm probably not leveraging Tastypie/Django-Piston functionality to the fullest. I'm not ready to make a full-fledged RESTful API for my app yet. I simply would like to use some of the AJAXy functionality that Backbone.js supports. Pros/Cons of doing this?

  • Screening (multi)collinearity in a regression model

    - by aL3xa
    I hope that this one is not going to be "ask-and-answer" question... here goes: (multi)collinearity refers to extremely high correlations between predictors in the regression model. How to cure them... well, sometimes you don't need to "cure" collinearity, since it doesn't affect regression model itself, but interpretation of an effect of individual predictors. One way to spot collinearity is to put each predictor as a dependent variable, and other predictors as independent variables, determine R2, and if it's larger than .9 (or .95), we can consider predictor redundant. This is one "method"... what about other approaches? Some of them are time consuming, like excluding predictors from model and watching for b-coefficient changes - they should be noticeably different. Of course, we must always bare in mind specific context/goal of analysis... Sometimes, only remedy is to repeat a research, but right now, I'm interested in various ways of screening redundant predictors when (multi)collinearity occurs in a regression model.

  • Using Maven shade plugin in a multi module project

    - by Manoj
    I have a scenario where-in I need to create an uber jar of a multi module maven project including all modules and their dependencies. I tried using maven shade plugin. but it seems to work only when I use it at the module level. If I add the plugin entry in parent pom then the build breaks (it tries to shade the parent pom) [INFO] Replacing original artifact with shaded artifact. [INFO] Replacing null with C:\Projects\foo.bar\target\foobar-0.0.1-SNAPSHOT-shaded.pom [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error creating shaded jar: null It does seem to make sense since the <packaging> for the parent maven project is pom. But there should be some way to create an uber jar for a multi module project... Any ideas people???

  • Django: way to test what class a generic relation content_object is?

    - by bitbutter
    In my project I have a class, NewsItem. Instances of NewsItem act like a wrapper. They can be associated with either an ArtWork instance, or an Announcement instance. Here's how the NewsItem model looks: class NewsItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') date = models.DateTimeField(default=datetime.datetime.now,) class Meta: ordering = ('-date',) def __unicode__(self): return (self.title()) In a template I'm dealing with a NewsItem instance, and would like to output a certain bunch of html it it's 'wrapping' an Artwork instance, and a different bunch of html if it's wrapping an Announcement instance. Could someone explain how I can write a conditional to test for this? My first naive try looked like this: {% if news_item.content_object.type=='Artwork' %}do this{% else %}do that{% endif %}

  • Translate model fields' attributes from a Database with Django?

    - by Luiz C.
    I'm trying to create a Model that has fields that have the following attributes translatable: verbose_name and choices. I can easily do this by tagging the strings and using the i18l middleware. The problem is that I don't want to define the translation in po/mo files. Is there a way to pull this data from a database table? If so, any examples? There are some options out there that offer model content translation. That is not my case. I need to translate the verbose_name, choices and error_messages from database.

  • Is it possible to use multi keyboards with multi keyboard layouts simultaneously?

    - by mono
    Considering to switch to dvorak layout, but this terminal is used by multi users as the same user account. It is unacceptable to ask all people to switch layout, plus it is hard to use dvorak layout with a keyboard qwerty-ly labeled. But there are spare (USB,qwerty) keyboards, so if I plug another keyboard in and be able to use multi layouts on different psyical keyboard simultaneously (I will rearrange letters on keys), the problem get solved. solution for either windows or linux is fine. anyway thanks all.
