Search in multiple models in Django
I have many different models in Django and I want to search for a keyword in all of them. For example, if you searched "blah", I want to show all of the products with "blah", all of the invoices with "blah", and finally all of the other models with "blah". I can develop a view and search in all of the models separately, but it's not a good idea. What is the best practice for this situation? -
DjangoCMS - Render database data to html
I'm testing out the DjangoCMS but I cannot understand how to create custom plugins that enable rendering data out of the database. I'd like to create a plugin that shows all the users for example but I can't understand how to pass the data into the HTML file. I followed the DJangoCMS documentation to create a custom plugin that shows the guest name, I've already tried to add users = User.objects.all() and then pass it to the render function but I receive an argument exception because the render function does not allow so many arguments, so what's the approach in DJangoCMS? models.py from cms.models.pluginmodel import CMSPlugin from django.db import models class Hello(CMSPlugin): guest_name = models.CharField(max_length=50, default='Guest') cms_plugins.py from cms.plugin_base import CMSPluginBase from cms.plugin_pool import plugin_pool from django.utils.translation import gettext_lazy as _ from django.contrib.auth.models import User from .models import Hello @plugin_pool.register_plugin class HelloPlugin(CMSPluginBase): model = Hello name = _("Hello Plugin") render_template = "hello_plugin.html" cache = False def render(self, context, instance, placeholder): context = super().render(context, instance, placeholder) return context -
Additional borders and wrong display when using class="d-none d-sm-block d-md-block" bootstrap

Django rest-framework , Serializer returning assertion Error

Combining annotation and filtering in Django for two different classes
Hi I am trying to query and count marketplaces for every infringement only for the logged in user. Essentially trying to combine these two. mar_count = Marketplace.objects.annotate(infringement_count=Count('infringement')) inf=Infringement.objects.filter(groups__user=request.user) I found a below example but this is for the same class.

Django Rest Framework: Upload file to another server via Django
I am building an API with DRF. The purpose of this API is to take user input and post the input to a different server via that servers API. There is also an option for users to upload file e.g. image. But the problem I am facing is that the second server is receiving the file as a blob of text like ����\x00\x10JFIF\x00\x01\x01\x01\x01,\x01,\x00\x00��\x0cXICC_PROFILE\x00\x01\x01\x00\x00\x0cHLino\x02\x10\x00\x00mntrRGB XYZ \x07�\x00\x02\x00\t\x00\x06\x001\x00\x... The second server is also build with Django. Here is the code for the first server that user has direct interaction with: requests.patch( f"https://second-server.com/api/user-upload/{self.kwargs.get('user_id')}/", data=request.data, ) The request.data contains the form data including the file that user is uploading. How can I save image to second server through the first server that user has direct interation with. -
Unable to find locate folder in python directory. Getting the error: ModuleNotFoundError: No module named 'config'
I am trying to import a .py file in my project using relative paths but I'm having some issues.

Django: managing permissions, groups and users during data migrations
Problem During a data migration, I'm trying to create a django.contrib.auth.models.Group and some Users and then attaching said group to one of the users. Problem I'm finding (other than the permissions still not being created, but I've already found a solution to that), is that for some reason the many-to-many manager doesn't seem to be working as it should (?). Basically what I'm trying to do is something like: group = Group.objects.create(name="manager") # user creation... user.groups.add(group) However, I get the following error: TypeError: Group instance expected, got <Group: manager> Whenever I try to replicate this in the Django shell, it works no problem. It only fails when in a migration. Any ideas? Things I've tried and other information I've tried both populating the m2m relation through the User related manager and the Group related manager, that is, user.groups.add(group) and group.user_set.add(user). Both give me a similar error. Just partially related, but just so I have the permissions needed, I have this first in my migration: for app_config in apps.get_app_configs(): app_config.models_module = True create_permissions(app_config, verbosity=0) app_config.models_module = None The group is supposedly created properly. Given that I create the groups and the users in different helper functions, I actually grab the group … -
How to handle FileNotFound error when using img tag using mark_safe in django admin

Django PasswordResetView does not work for inactive users
I have a simple django app where users can create and login to their accounts. When a user is registering for a new account, the user object is created and saved in the database with the is_active flag set to false. Once the user clicks the confirmation email, the user object has its is_active flag set to true. I have built out a password reset flow using Django's views: PasswordResetView, PasswordResetDoneView, PasswordResetConfirmView, and PasswordResetCompleteView. Everything works as expected unless I am trying to reset the password for an account which has not yet been activated (is_active == False), in which case, the reset password email is never sent to the user. The edge case I am considering here is for a user who created an account, and never clicked the registration link which expires after 72 hours, and thus have a user account which exists but is not active. Then the user wants to get a new registration link, and to do so I require a user to enter their username and password (so that no malicious actors can spam a random users email inbox with new registration link emails). If the user has since forgotten their password, they are … -
Displaying Countdown in Django Loop not working properly when clicked

How to show all the tags related to a publication in a list of publications filtered by a tag in Django?
Consider following models: # models.py from django.db import models class Tag(models.Model): name = models.CharField() number_of_publications = models.PositiveIntegerField() class Publication(models.Model): text = models.TextField() tags = models.ManyToManyField(Tag) # urls.py from .views import publications_tagged urlpatterns = [ path('/questions/tagged/<str:name>', publications_tagged) ] # views.py from .models import Tag, Publication from django.shortcuts import get_object_or_404, render def publications_tagged(request, name): tag = get_object_or_404(Tag.objects.prefetch_related('tags_set'), name=name) return render(request, 'myapp/tagged_questions.html', {'tag': tag}) Ok, so when we'd go to a template and make a for-loop that will create a representation of every publication and show appropriate tags of it, Django would make a database call for every publication to fetch all the tags the publication has, meaning: Iteration x of tag.tags_set -> check what tags match with publication X. Of course, we can just not show tags and everything will work like magic (utilizing prefetch_related), but that's not what we want :) How could we do something similar in Django? What we want is some kind of optimized way to achieve such a result, because stackoverflow renders 15 items really fast, which makes me think they do not do it the monkey way that Django does by default. This is what html might look like P.S. My problem doesn't quite sound like … -
How can I prevent row duplicates in Django when no field is unique?
Upon saving an object, is there a simple way to prevent duplication when the combination of all the fields together have the same data? The unique=True parameter doesn't seem to help here, because individually any of the data could be duplicated, but never all of them at the same time. If statement with several and conditions does not seem to me like a smart way so I'm looking for a better approach. Does Django provide it? All I could find was related to one field or other being duplicated. Ex.: if Model.objects.filter(field_A=source_A).exists() == True and Model.objects.filter(field_B=source_B).exists() == True and Model.objects.filter(field_C=source_C).exists() == True: continue else: *save object* -
