Phantom Postman in Django App
I've encountered a strange problem in my django site-- the django-postman app is present but can't be edited nor deleted. I need to tweak the views but none of the changes work. I've even deleted the entire URLs and views and the postman app works fine. I thought there might be a duplicate directory that has all these files, but thats not it. What else could be the issue here? And what is a solution? -
Is pyenv or virtualenv enssential for Django?
For the first time, I made an environment for Django with virtualbox and vagrant (CentOS 7). But every tutorial I saw says I need to use pyenv or virtualenv. I think they are used to make a virtual environment for Django. But I don't know why I need to use pyenv or virtualenv. (For example, Cakephp3 doesn't need packages like pyenv or virtualenv.) And I was using virtualbox and vagrant, which are already virtual environment, so I think I was making virtual environment inside another virtual environment. I am not sure if this is meaningful. Maybe pyenv and virtualenv are not necessary if I am using virtual environment like virtualbox or vmware? Are they essential for Django? When I deploy Django in actual server, do I still need to use pyenv or virtualenv? -
Nginx default page showing. Cannot get app to display
first time Nginx user. Trying to connect Nginx to Gunicorn running a django app. The app is not actually written yet so once everything is configured, it would just display an under construction page.

Django test setup not being used
I am using Django cookiecutter 1.11 for a project. Trying to write some basic tests for a model. But the setup method is not being used in the test cases. from django.test import TestCase from myapp.users.models import User from ..models import Book class ModelTests(TestCase): def setup(self): self.username = 'john' self.password = '123' self.user = User.objects.create(name=self.username, password=self.password ) def test_create_book(self): Book.objects.create(artist=self.user, title=“An Art Book“, category=“Art”, ) self.assertEquals(Book.objects.all().count(), 1) I get this error message after running manage.py test Book.objects.create(artist=self.user, AttributeError: 'ModelTests' object has no attribute 'user' But it works when I put the lines from setup into the test case. Did I miss something? -

Json Fields search with django unexpected behavior
Hi guys Im seeing a behavior than i don't understand in django postgres json search. Im Using django 1.11 and django orm with psycopg2 driver. It goes as follows: The json in the model field looks like this. {"2018": [1, 2, 3]} If I use this query: models.mymodel.objects.filter(jsonfield__2018__contains=1) Out[97]: <QuerySet []> So as you can see i get an empty query. Then I tried to do this just for testing purposes. New Json: [ {"2018": [1, 2, 3]}] New Query: models.mymodel.objects.filter(jsonfield__0__2018__contains=1) Out[98]: <QuerySet []> It still gives me no response. Then I finally tried this. New Json: [ {"2018_1": [1, 2, 3]}] New Query: models.mymodel.objects.filter(jsonfield__0__2018_1__contains=1) Out[100]: <QuerySet [<MyModel: MyModel object>]> This one responds and I cannot wrap my head around it. Does anyone know why is this? -
Lost my app.sock file while setting up my Django server on Digital Ocean
In the mix of renaming files/moving files/directories between my server and my Bitbucket repo, the app.sock file was removed. How do I get it back? I was following this tutorial whilst setting up my server. Previously the server comprised of env (virtual environment), static, draft (my app), draft1.sock and manage.py - now it's the same but draft1 is renamed to olddraft and the sock file is gone. So how do I retain the sock file? -

Heroku H12 errors with Django
I have a Djano 1.8 application running on 6 Heroku dynos. Every once in a while, a request that is normally very fast (200ms) comes in and hits the Heroku router 30 second timeout. Then that dyno times out other follow-on requests, sometimes taking 25 minutes to stabilize and go back to serving requests without timing out. I'm using gunicorn with default web_concurrency (2 workers per dyno). I read Heroku's article on timeout behavior here, and am considering adding something like --timeout 20 to my gunicorn startup in the Procfile. That seems to be what they are recommending. Do you think that will solve the problem? From looking at the gunicorn documentation on the timeout setting it says: Workers silent for more than this many seconds are killed and restarted. But my workers aren't silent are they? They are trying to process requests but are hung and unable to for some reason. Do I understand that correctly? -

Is it possible to use django-filter OrderingFilter with function based views?
I'm trying to create an order by dropdown in a template that will order a queryset by fields of my model. Picture of ordering menu I'm going for I understand how to use the django-filter package to filter by model but I can't find any documentation on how to use the OrderingFilter without using class based views.

Can't login users with specific permissions
I'm creating a school, kinda, and I created a group called Instructors. Instructors are users with permission to create courses. They have all permissions of the courses application except those of the Subject model).

How to use GPS location in Django REST API?
I am making a REST API with Django for a restaurant search app. I need to get a list of restaurants within a distance of X meters from my location. I am not sure how to store this on my database (I am using PostgreSQL) and how to retrieve this list. I searched online some options and I found PostGIS as an extension to Postgres that can be used in Django, but I still want to listen to some of your recommendations. Thank you -

Circular model references
I am not quite sure about the best/idiomatic way to approach the following: I have a model called BlogPost and a model called BlogPostContent. BlogPost has a field called CurrentContent which references a related record in the BlogPostContent table. BlogPostContent has a foreign key field called Post referencing its related BlogPost. When a blog is modified, a new BlogPostContent record is created, and the BlogPost is updated such that its CurrentContent field references the newest BlogPostContent. I do this so it is possible to provide a way to rollback and specify any BlogPostContent record to use the CurrentContent It is possible for the CurrentContent to reference ANY of the BlogPostContent records related to it. If I were to model this in code, it would be: class BlogPostContent { //Content } class BlogPost { BlogPostContent currentPost; List<BlogPostContent> contentHistory; } -

Named groups with slashes in Django URLs
I have a set of following URLs defined: GET /data/(?P<tag>[^/]+)$ POST /data/(?P<tag>[^/]+)/action_1$ POST /data/(?P<tag>[^/]+)/action_2$ ... I would like to know whether it is possible to use tags containing slashes? E.g., when I try to get the data for the tag a/b/c, I always obtain 404 errors. Although I quote tags before forming actual URLs (i.e. /data/a%2Fb%2Fc for the previous case), the obtained URLs still do not match (though a%2Fb%2Fc should match [^/]+), because it looks like Django performs implicit unquoting, which is undesired. How can I overcome this problem without changing the URL forming scheme? -
Issue migrating DB from Local to Heroku Django
I've been working on a Django application and have recently run into a few issues pushing updates and migrating DB settings from Local to Heroku. I followed these steps: I added a few columns to my app model. Then ran python manage.py makemigrations then python manage.py migrate. I then committed these updates via github. Then I ran git push heroku master w/ Heroku CLI Then I entered heroku run python manage.py migrate Unfortunately, this did not migrate the appropriate updates I made to the DB settings in my local dev environment. The error message I received is "Column x does not exist in X-app". I ended up reverting back to my previous settings in model.py temporarily, but I would like to eventually add new columns to my database. At this point, I'm trying to assess what the best solution is to the problem. I've reviewed several other Stack Overflow questions, but haven't found one that's worked for me yet. What's odd is that I was able to migrate successfully in previous Heroku deployments. Any tips anyone has would be extremely appreciated. For reference, I'm using Python 3.6.2 and Django 1.11
