Django caching requests regardless of settings
I' have a page called 'results.html' from which a user can submit a form. The problem is that sometimes I submit the form and the response is taken from the cache, and other times it actually calls the response method in views.py. Here's an example: User submits 'The Imitation Game': the correct response is returned to the user and my response function in views prints [19/Nov/2016 00:50:21] "POST /results/ HTTP/1.1" 200 2414 Response function called!! Search term: The Imitation Game` to the console. However, if the user searches this again (or any other search term he/she searched in the past) this is the response: [19/Nov/2016 00:51:05] "GET /get_data?query=The%20Imitation%20Game HTTP/1.1" 200 18858 Clearly the response method was not called at all. This is also very evident on the front end because out-of-date data is returned to the user on subsequent requests. The kicker here is that I am using a dummy cache: # Use dummy cache for development and testing CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.dummy.DummyCache', }, 'deployment': { 'BACKEND': 'django.core.cache.backends.locmem.LocMemCache', } } and DEBUG = True. I am also marking the response method as follows: @never_cache def results(request): I cleared my browser cache, so it's not that either. I'm … -
Transferring GeoJson data to MongoDB modeling from Django Models
My Django project is currently set up with MongoEngine to connect to my MongoDB database. I'm working on the map data loading and right now depends from a Geojson file. Being new in working with MongoDB to use in creating a collection based from an existing file I would like to know if it's possible to transfer Geojson data based from my existing model.py For example I have this snippet of Geojson data: { "type" : "FeatureCollection", "features" : [ { "type" : "Feature", "route_id" : "ROUTE_880801", "geometry" : { "type" : "LineString", "coordinates" : [[120.9834301, 14.60350785], [120.9924853, 14.60077731], [121.005038, 14.60173248], [121.017, 14.6042], [121.026, 14.6105], [121.034, 14.6136], [121.043, 14.6185], [121.053, 14.6227], [121.065, 14.628], [121.073, 14.631], [121.086, 14.6223]] }, "properties" : { "name" : "name1" } } , { "type" : "Feature", "route_id" : "ROUTE_880801", "geometry" : { "type" : "LineString", "coordinates" : [[121.086, 14.6223], [121.073, 14.631], [121.065, 14.628], [121.053, 14.6227], [121.043, 14.6185], [121.034, 14.6136], [121.026, 14.6105], [121.017, 14.6042], [121.005038, 14.60173248], [120.9924853, 14.60077731], [120.9834301, 14.60350785]] }, "properties" : { "name" : "name2" } } ] } and my models.py from mongoengine import * from colorful.fields import RGBColorField class Line(Document): id = StringField(required=True) rLine = LineStringField() name = StringField(required=True) color = RGBColorField() … -
Django MySQL server has gone away
I have a django site the was using sqlite for the backend, recently we upgraded to MySQL and now are receiving intermittent 'MySQL server has gone away' errors. After starting the site it loads fine, clicking around to change pages will result in the error usually after viewing 1 to 6 pages. The page it occurs on appears to be irrelevant, the same page may load fine the first time but throw the error the 2nd time. Here's my environment Nginx running on host machine as reverse proxy Docker container running Nginx inside, Django 1.8, uwsgi, and Python 3.4. Django is using the mysqlclient db driver. Google Cloud MySQL, 2nd generation I've tried using a local MySQL server rather than the Google Cloud MySQL, it didn't make a difference. I also tried using the MySQL Connector/Python DB driver instead of mysqlclient. It produced a different (but similar) error message and traceback. If I go back to sqlite, it works fine. Running under the django development server rather than nginx also works fine. I've seen posts for this error stating that the django CONN_MAX_AGE should be less than the MySQL wait_timeout, but I'm using the default CONN_MAX_AGE setting of 0. According … -
Extra fields Django-registration Forms
Good evening, I am using django-registration for a Web application; By using this, the form that has default django-registration only has 4 fields (username, email, password, repeat password). How to add more fields to this form and store them in the database correctly? Thank you. -
Filter objects with empty generic content
My notification model is generic, meaning it can hold any object. It looks like this: class Notification(models.Model): receiver = models.ForeignKey(User, related_name='notifications') sender = models.ForeignKey(User, related_name='sent_notifications', blank=True, null=True) object_type = models.ForeignKey(ContentType, blank=True, null=True) object_id = models.PositiveIntegerField(blank=True, null=True) object = GenericForeignKey('object_type', 'object_id') type = models.CharField(max_length=3, choices=config.NOTIFICATION_TYPE_OPTIONS) unread = models.BooleanField(default=True) slug = models.SlugField(max_length=255, unique=False, default='notification') # Other date_created = models.DateTimeField(auto_now=False, auto_now_add=True, blank=True) date_modified = models.DateTimeField(auto_now=True, auto_now_add=False, blank=True) Whenever a user deletes an object that a notification relates to, it ends up pointing to a NoneType object instead. I want to filter out Notifications that don't relate to anything to the user. I've already tried: Notification.objects.exclude(object=None) and Notification.objects.filter(object=None) However both gives me an error that I cannot do a reverse relationship query on generic content type objects. How do I filter or get all Notifications that are pointing to non-existing objects? -
Use SQLite for Django locally and Postgres on server
I am starting with Django development as a hobby project. So far I have happily worked with SQLite, both in development (i.e. with py manage.py runserver) and in deployment (on Nginx + uWSGI). Now I would also like to learn to use a more robust PostgreSQL database. However, if possible, I would like to skip installing it locally, to avoid installing Postgres on Windows. I was wondering if it was possible, by means of Django, to use SQLite whenever I use the built-in server and Postgres in deployment, without changing the project code. Couldn't find how to do it. I can use a workaround and make my deployment procedure change the settings on server each time I deploy. But that's kind of a hack. -
How get multiple resultset / cursors with django and postgresql?
Taking the example from http://trentrichardson.com/2012/01/04/return-multiple-result-sets-with-php-and-postgresql-functions/, I wanna return multiple results to a view. I have this code now: CREATE OR REPLACE FUNCTION load_deuda(cobro CHAR) RETURNS setof refcursor AS $$ DECLARE c_cobro refcursor; DECLARE c_deudas refcursor; BEGIN OPEN c_cobro FOR SELECT * FROM "recaudo_cobro" ORDER BY "recaudo_cobro"."nombre" ASC; RETURN NEXT c_cobro; OPEN c_deudas FOR SELECT id, orden FROM cliente_deuda WHERE cobro_id=1 AND estado='ACTIVA' ORDER BY orden; RETURN NEXT c_deudas; END; $$ LANGUAGE plpgsql; def exeSql(cobro, tables, params=None): from django.db import models, connection sql = "SELECT load_deuda('%s');" % cobro; for i, table in enumerate(tables): sql += '\nFETCH ALL IN "<unnamed portal %d>";' % (i + 1) print(sql) with connection.cursor() as c: c.execute(sql) for i, table in enumerate(tables): yield c.fetchall() However, this return me the last cursor. How get all of them? -
Django: Search stopped working in 1.10
I've been working on an application I originally started in Django 1.7, then ported it over to 1.10, where it stopped working. It will work if I select a District to search by, but only by the District. What I'm hoping is that if all the search terms are left blank, it will return all objects in that pool. It would be great if anyone had some ideas on where this is going wrong, as it doesn't give me errors, just tells me there are no results.

How to tell list from non-list in Django template?
I've got a Django template I'd sometimes like to pass a list and sometimes like to pass a single value. How can the template tell which it was given? I'm thinking the value would be set like one of these: context = { 'foo' : 'bar } or: context = { 'foo' : ['bar', 'bat', 'baz'] } Then, the template would have code that looks something like this: {% if foo isa list %} {% for item in foo %} {{ item }}<br> {% endfor %} {% else %} {{ item}}<br> {% endif %} I can set it up to have foo or foolist, for example, and check for one or the other. However, it'd be a bit nicer (imo) to just have foo that was either a list or not. -

Django Queryset compare two different models with multiple rows
I have these two models that I would like to return the sum of. I get an database error about the subquery returning more than one row. What would be the best way to compare both without using a for statement?

Problems with using django-crontab in Heroku (Django project)
it is impossible for me to run cron jobs using django-crontab in heroku. Cron job seems to run fine for me locally but failed in heroku server.

django django-allauth save extra_data from social login in signal
Setup I'm using Django 1.8.15 and django-allauth 0.28.0 Description What I want to do is pretty easy to explain: If a user logs in via social media (facebook, google+ or twitter) i want to retrieve the extra_data from sociallogin to get the url to the avatar and other information to store it in my Profile, which is a One-to-one relation to my User model. My approaches 1) First I added a class with pre_social_login like here which gets called after the user has signed in via social media. models.py class SocialAdapter(DefaultSocialAccountAdapter): def pre_social_login(self, request, sociallogin): """Get called after a social login. check for data and save what you want.""" user = User.objects.get(id=request.user.id) # Error: user not available profile = Profile(user=user) picture = sociallogin.account.extra_data.get('picture', None) if picture: # ... code to save picture to profile settings.py SOCIALACCOUNT_ADAPTER = 'profile.models.SocialAdapter' I want to get the instance from the user but it seems, that it wasn't created yet. So I tried the following: 2) I have another signal which creates a profile if a new user is added: models.py @receiver(post_save, sender=settings.AUTH_USER_MODEL) def create_profile_for_new_user(sender, created, instance, **kwargs): """Signal, that creates a new profile for a new user.""" if created: profile = Profile(user=instance) # following … -
Why can't I update pip on Windows 7?

Django - How can I debug code which POST's when a bug seems to be in the view?
I thought I would ask a broad question so I get a better understanding of Django and can more readily deal with any similar problems I may encounter. The specific issue which I am having is that I have written my first formset code, which renders the forms correctly but when posted no new objects are created. I can see from the server that the form has been posted, I get no errors but no data has been added to my database (checked from django admin and manage.py shell). Perhaps it is possible to read what has been posted in a manage.py shell? I would like to be able to check whether the form posted its data correctly and it has been received by the view. Then I can see why either the data isn't posting correctly or the view isn't handling it correctly. For the specific issue I will place my code below, in case it's a simple beginner error which one of you wizards can spot. I tried to follow and adapt this tutorial for my own purposes. Models.py class Chunk(models.Model): name = models.CharField(max_length=250) text = models.CharField(max_length=500) images = models.FileField() question = models.CharField(max_length=250) expected_completion_time = models.IntegerField(default=1) keywords = … -

When running the database on localhost it works fine. You can add/remove people etc on django. But when i deploy on eb it doesnt seem to work even though it works perfectly fine on localhost.Thanks! -
RapidSMS Twilio Django - SMS Application Architecture
I am learning SMS application dev with RapidSMS Django. I came across rapidsms-twilio for backend. I am lost here and trying to make sense of overall architecture and technologies associated with each layer. It will help me in future research of better alternatives. Similar to web applications JS/Ajax/css/html are front end tech with java in app layer and db on backend how could i layout SMS application framework? From my understanding Twilio will provide a number so whenever text is received on number it will receive it in SMMP format and convert it to HTTP and call app server URL mapped against it which could be in django. Where and what does rapidsms do here? -
