How to resolve the django migration conflict?
There was a situation when a message appeared on the server CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0063_auto_20200530_1040, 0062_merge_20200527_1444 in vendors). To fix them run 'python manage.py makemigrations --merge' I followed the command, but now a new migration file has appeared during the execution Created new merge migration /home/ubuntu/spend-matters/apps/vendors/migrations/0064_merge_20200601_0807.py But the local machine and github don't have this file, so every time I pull a new code from github to the server, there will be a problem with the difference in migrate. How do I fix this correctly? -
Object received a naive datetime (...) while time zone support is active
I've been looking for an answer for this with no luck. I'm creating and object that has an attribute called "accessdate" When I create the object I receive the next warning RuntimeWarning: DateTimeField Consumption.addedtime received a naive datetime (2020-06-01 13:07:47.222534) while time zone support is active The thing is that what the object is reciving is NOT a naive datetime because it has the tzinfo filled with "Europe/Madrid" timezone. These are the relevant imports I'm using: import datetime from django.utils.timezone import make_aware This is how I create my datetime variable: date_object = datetime.datetime.strptime(data_from_request['FECHA ACTIVACION'], '%d/%m/%Y') # data_from_request['FECHA ACTIVACION'] = '01/01/2020' access_date = make_aware(date_object) And this is how I create the object consumption = Consumption.objects.create( client=client, rule=rule, course=course, provider=provider, usercode=data_from_request['CODIGO USUARIO'], username=data_from_request['NOMBRE USUARIO'], accessdate=access_date, billable=data_from_request['FACTURABLE'], status=data_from_request['VALIDADO'] ) How is this possible? I'm debugging my code and when I check for the "access_date" variable content I can see the tzinfo filled Why am I still getting this warning? Thank you guys ! -

Vote only once in Django to posts and comments
I have two models called Post and Comment and a User that can upvote or downvote that post or comment. I want to restrict each user however to be able to to vote only once to a certain Post or Comment. I could do something on the model level to Post and Comment and instead tally up total votes for the specific post or comment. However, I think it's a bit more scalable to create a separate Vote model where: total votes can be tallied with one query (SELECT count(*) FROM votes where user_id=, etc...) voting once per user can be enforced with unique_together Currently I have figured out something like this: import uuid from django.db import models from django.contrib.auth import get_user_model from django.db import models # Create your models here. class Post(models.Model): LINK = "link" VIDEO = "video" IMAGE = "image" POST_TYPE_CHOICES = ((LINK, "Link"), (VIDEO, "Video"), (IMAGE, "Image")) id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) created = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=300) url = models.URLField(max_length=300) category = models.CharField(max_length=50) score = models.DecimalField(default=0, max_digits=20, decimal_places=2) votes = models.IntegerField(default=0) views = models.IntegerField(default=0) post_type = models.CharField(max_length=5, choices=POST_TYPE_CHOICES, default=LINK) text = models.CharField(max_length=40000) owner = models.ForeignKey('users.User', related_name='posts', on_delete=models.CASCADE) def __str__(self): return self.title class Meta: ordering = ["-created"] … -

Django - Create proposals from many tables
Have a look at the following code snippet: def post_proposals(count): post_elements = chain( PostModel1.objects.all(), PostModel2.objects.all(), PostModel3.objects.all(), ) post_elements_list = list(post_elements) post_proposals = random.sample(post_elements_list, count) return post_proposals Where it's requiered to generate a list of proposals from 3 different Post tables, how to optimize a disgn flaw like this? Already came accorss the idea to build a Index table where all PKs of all my PostModel{1..3} are stored, so that I just have to query 1 table instead of three. Does smb. have a practical idea on how to solve this or at least optimizing it? -
How can I reduce loading speed while sending mail - Django

Django DRF issues when running session & token (knox) authentication simultaneously
I have a site that I am moving to single page application design. I need the old site and the new site to be able to run simultaneously, the old site uses the DRF API too. In my settings.py, I have the following: REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'knox.auth.TokenAuthentication', 'rest_framework.authentication.SessionAuthentication', ), } The problem that I am having is that, if I am logged into the old site and try to log onto the new site from a different browser window, I get the error message: 'CSRF Failed: CSRF token missing or incorrect'. If I log out of the old site then I can log into the new site and everything works fine. -
Class view with post, get and data
I have practically finished the microblogging application and I want to change to class base views now. I read about generic views, but it looks like each of them has specific properties. In my index view I display two models and two forms, so I created IndexView (View) and put the get and post functions there and it works, but it doesn't look like there are any benefits of class views, so I'm probably doing something wrong. Currently, several views repeat a lot of code, and I thought that class views would solve this problem. I would like an example of how such a view should be written as class view with reusable get. if request.method == 'POST': post_form = AddPostForm(request.POST) comment_form = AddCommentForm(request.POST) if post_form.is_valid(): new_post = post_form.save(commit=False) new_post.author = request.user new_post.tags = '' content = '' for word in new_post.content_post.split(): if '#' in word: new_post.tags += f"{word} " content += f"{word} " else: content += f"{word} " new_post.content_post = content new_post.save() for word in content.split(): if '@' in word: print(word) user_to_notificate = CustomUser.objects.get(username=word[1:]) new_notification = TalkAbout() new_notification.where = new_post new_notification._from = new_post.author new_notification.to = user_to_notificate new_notification.sended = False print(new_notification) new_notification.save() post_form = AddPostForm() if comment_form.is_valid(): new_comment = comment_form.save(commit=False) … -

unique constraint on the basis of foreign model field value django
I have three model in django applications. for example: class A(models.Model): field1 = models.CharField(..) field2 = models.CharField(...) class B(models.Model): field1 = models.CharField(..) field2 = models.CharField(...) class C(models.Model): field1 = models.ForeignKey(A, ..) field2 = models.ForeginKey(B, ..)
