Vue custom delimiters not working in Firefox
I have a django project and I want to start adding Vue.js elements into it, but there is a big overarching issue before I can really start in that custom delimiters (template tags) do not work in the firefox browser only Chrome, I can change them from curly braces to square brackets, but in firefox it just renders the code not the message. The following code is not part of my django project, it is just example code to demonstrate the issue. <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <script src="https://cdn.jsdelivr.net/npm/vue"></script> <title>Learning Vue.js</title> </head> <body> <div id="app"> <input type="text" v-model="name" /> <p>Hello [[ message ]]</p> </div> <script> new Vue({ delimiters: ["[[","]]"], el: '#app', data() { return { message: 'Hello World' }; } }); </script> </body> </html> So this code renders the following in Chrome: Hello World! And in Firefox, it renders the code: [[ message ]] I'm assuming there is a fix for this, as I almost never see rendered code in websites and I'm assuming Vue is popular, how do other developers get around this issue? -
Django Rest Framework: PageNumberPagination doesn't work
I've created an APIView to list all posts of a blog: from ..pagination import BlogPagination class BlogPostAPIView(APIView): pagination_class = BlogPagination permission_classes = [IsAdminOrReadOnly] def get(self, request): objects = BlogPost.objects.filter(draft=False, publishing_date__lte=Now()) serializer = BlogPostSerializer(objects, many=True) return Response(serializer.data) def post(self, request): serializer = BlogPostSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) I've also created a pagination.py: from rest_framework.pagination import PageNumberPagination class BlogPagination(PageNumberPagination): page_size = 5 With this code I see all posts and not five posts for page. I'm using Django 3.1.5 and DRF 3.12.2 I've the same problem if I use the global pagination in settings.py REST_FRAMEWORK = { 'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination', 'PAGE_SIZE': 5 } -

How can I add an action to the Django User admin page?
I'm using Django 3.0. I want to add an action to the User ChangeList in the admin. The documentation for admin actions indicates that to add an action to an admin page, I need to add either the method or a reference to it to the Model's admin.ModelAdmin subclass in admin.py: # admin.py from django.contrib import admin def make_published(modeladmin, request, queryset): queryset.update(status='p') make_published.short_description = "Mark selected stories as published" class ArticleAdmin(admin.ModelAdmin): list_display = ['title', 'status'] ordering = ['title'] actions = [make_published] or # admin.py from django.contrib import admin class ArticleAdmin(admin.ModelAdmin): ... actions = ['make_published'] def make_published(self, request, queryset): queryset.update(status='p') make_published.short_description = "Mark selected stories as published" Since the User Model's admin.ModelAdmin subclass is in the auth system and not in my admin.py, though, I don't know where to put the code for this case. I tried following user Davor Lucic's answer to a much older but similar question from django.contrib.auth.models import User class UserAdmin(admin.ModelAdmin): actions = ['activate_user','deactivate_user'] def activate_user(self, request, queryset): queryset.update(status=True) def deactivate_user(self, request, queryset): queryset.update(status=False) activate_user.short_description = "Activate user(s)" deactivate_user.short_description = "Deactivate user(s)" admin.site.unregister(User) admin.site.register(User, UserAdmin) When I try this, the server halts with the error File "Project/env/lib/python3.6/site-packages/django/contrib/admin/sites.py", line 144, in unregister raise NotRegistered('The model %s is not … -
Django: Load information from file and edit before saving
I have a bib tex file with a lot of sources, which I want to import within the django admin and edit them before saving. At the moment I have an uploader, where all resources get saved, when I click save. Afterwards I can go to the resources, open each and edit them manually. Does somebody know how to load the information into the admin page from the file, so I can edit them before I save the information? Should look like this. Question would be my file uploader and each Choice (Resource) would be prefilled with information. There should not be a foreign key between the file and the resources.: Thanks in advance. -
Programatically setting a Model's Fields in Django
Say I have a model Food class Food(models.Model): description = models.TextField() toppings = models.TextField() scheme = models.ForeignKey(FoodScheme, models.CASCADE) And I want to have another class, a FoodScheme which describes which of the fields must be set in a specific Food class. class FoodScheme(models.Model): scheme_name = models.TextField() requires_description = models.BooleanField(default=False) requires_toppings = models.BooleanField(default=False) But instead of hard coding this, I want to programmatically set these fields up, so any change in Food will change the FoodScheme class too. An example implementation (that doesn't work, for several reasons, but I think gets my point across): class FoodScheme(models.Model): scheme_name = models.TextField() for f in Food.get_fields(): setattr(self, f"requires_{f.name}", models.BooleanField(default=False)) Any ideas would be greatly appreciated. -

How do I filter out the friends of current user from a search_users function (Django)
I'm trying to filter out the friends of a user also the user themselves from a search users function, I've tried using the exclude() parameter but I'm not sure what I'm doing wrong, as you can see from my views.py the search_users function has a exclude on the end of object_list, but this didn't work.

How do I make the makemessages command detect default django translations (like form validation error messages)?
The site I'm developing is multilingual and the secondary language is not supported by default. I have added it in the settings file like so. EXTRA_LANG_INFO = { 'am': { 'bidi': False, # right-to-left 'code': 'am', 'name': 'Amharic', 'name_local': u'አማርኛ', #unicode codepoints here }, } The error_messages that I overwrite and use are correctly translated and detected by the makemessages command. error_messages = { 'password_mismatch': _('The two password fields didn’t match.'), } But the default validation exception error_messages that I did not overwrite do not appear in the .po translation file. It would be much easier to find out a way to make the command also render translations for those strings, as opposed to me overriding on every time it appears. Thanks. -
How would you model these database relationships? (User, Competence, Interest)
I'm working with a Django system and the thing is pretty simple actually, but one thing got me bothered and I thought that must be a better way to do it. Basically it's an internal tool for searching the developers the company has available to allocate them in projects based on their skills and interests. So let's say Employee John can add a Topic React to his list of competence and select his skills levels from 1 to 5 stars, meaning 1 = total beginner and 5 = expert. He can also select his level of interest from 1 to 5. So you can have a list like below The way this is designed at DB is like this: Table user with all relevant user information Table knowledge_topic with columns [id, label], where label is just the name of the language/tech Table knowledge_level with columns[id, knowledge_level, interest_level, topic_id, user_id] where topic_id makes the relationship to knowledge_topic table and user_id to user table The competence list endpoint can give a result like this for example: [ { "id": 2, "topic": { "id": 8, "label": "Docker" }, "interest_level": 4, "knowledge_level": 2, "user": 2 }, { "id": 5, "topic": { "id": 9, "label": … -
Error while using pghistory.BeforeDelete() of django-pghistory
