Mezzanine project structure - virtual env in project folder?
So I'm attempting to deploy my mezzanine site, but I have run into some issues with settings not being installed properly on the digitalocean server. After checking some videos, like this one: https://www.youtube.com/watch?v=RIOUwi-1DCg I notice that he and others have their virtual env inside the project folder, next to the mezzanine project. Is this the correct way to structure the project? In my case, the virtual env is in a seperate Env folder with my other virtualenvs under my main directory on Windows 7. If someone could clarify what the structure should look like, and perhaps why, I would be grateful. -

How to find the correct relationships between my tables?
I'm trying out a new django social media project which has User, Status and Comment. The relationship between them is such that, User has a relationship to Status, User has relationship to Comment and there also exists a relationship between Status and comment. So to achieve this I built four tables, i.e, User, Comment, Status and UCSModel. Where UCSModel is the table which has the foreign keys of the rest three tables. UCSModel is more like the relations table consisting of all ID's So here is my models.py from django.db import models class User(models.Model): username = models.CharField(max_length=50, unique=True) email = models.CharField(max_length=200) password = models.CharField() def __str__(self): return self.username class Comment(models.Model): comment = models.CharField() def __str__(self): return self.comment class Status(models.Model): status = models.CharField() def __str__(self): return self.status class USCRelation(models.Model): user = models.ForeignKey(User, null=True, on_delete=models.CASCADE) comment = models.ForeignKey(Comment, null=True, on_delete=models.CASCADE) status = models.ForeignKey(Status, null=True, on_delete=models.CASCADE) Being new to Django, I wanted to know if there is any better way of building relationships between tables. Especially when all the three tables are interrelated to each other like in my case above. -
Django Test case for deleting a post returns Https 200 instead of 302
I am writing a test case for a Posts app in my Django project. I have defined views for adding a new post, listing the posts, view details of the post, edit a post and delete a post. Adding a new post redirects the page to the detailed view of that page and deleting a post redirects the page to the list view. While writing tests for the same, I am getting https response code 302 for the new post as expected, but for the delete post, I am only getting an https response 200 while it should be 302. Adding necessary code below. Please feel free to ask any more code related to this if needed. Is there any concept that I am missing? Any lead is welcome. Thanks in advance.

gunicorn v job queue in django
In Django webapp that's deployed, I get request in views.py As soon as post request is received, I modified post function to do certain action and deliver results in views.py def post(self, request, *args, **kwargs): #do some action #deliver results to 1.1.1.1 In this case, I'm currently running task as the request comes. For instance, if 5 requests come in at once, it's currently processing one by one. But, I'd like to process all requests at once(assuming there are enough server load) and deliver results back. Would increasing workers in gunicorn solve the issue of concurrency or would it be better to utilize job queue like celery? If gunicorn is enough, how many workers would need to be set? And what is best practice method? -

See if Django form submission came from the admin

Why doesn't this Django filter by 'annotate' variable work?
I have this queryset in Django: obj = Obj.objects.annotate(duration = F('date_end') - F('date_start')).order_by('duration') The following works perfectly: obj[0].duration obj.aggregate(Sum('duration'))['duration__sum'] However filtering doesn't work in this case even though documentation says that it should: obj = obj.filter( duration__gte = <a_class_datetime.timedelta> ) # doesn't work obj = obj.filter( duration = 1 ) # doesn't work This is the error I am getting: TypeError: expected string or bytes-like object My way to bypass this issue is to loop through the dataset - which is huge. Any tips as to why this is not working? -
ModuleNotFoundError: No Module named 'django' when trying to run makemigrations
I have taken over maintenance of a deployed Django app that is used by employees. I have made minor changes here and there and I only had to restart the apache to implement the changes. For the first time, I have to add an integerfield model to one of the pre-existing models. This said value is already in the DB with default value of 0 for all rows. All I want to do is add it as one of the fields in one of the models but when I try to run sudo python3 manage.py makemigrations in the virtual environment, I get ModuleNotFoundError: No module named 'django' The above exception was the direct cause of the following exception: Traceback(most recent call last): File "manage.py", line 14, in <module> ) from exc As the app is currently running fine, why am I receiving this error? If this is not how you apply changes in the model field in the live server, how else are you supposed to do it? Thank you so much! -
