django modified_at field with database level auto update
I need to have modifed_at fields in my Django project. A field that updates every time a row updates in the database, despite where the update comes from: through calling .save() or through queryset.update() or even when updates happen in the database directly and not from the Django app. there is an auto_now property that does not solve my problem according to this SO question(based on Django document). other SO questions(like this and this) ask the same thing, update instance at every change not only .save() This problem can be solved using triggers as said here but this way we need to write the same trigger for every modifed_at field in models. as discussed in this Django ticket this probelem will not be addressed and solved in Django. even the suggested patch only updates the instance if it changes via Django. the only way that comes to my mind is to do something like this in a mixin. a mixin that when inherited creates a trigger for fields with auto_now=True. maybe change SQL when Django creates the model creation SQL. but I don't know how to implement this. so I have two questions: what is the best way to achieve … -
Corrent Way to Structure Models, Views and Serializers
I have the following structure of Parent and Child models, where the child references the parent. class ParentModel(models.Model): name = models.CharField(max_length=255) class ChildModel(models.Model): name = models.CharField(max_length=255) parent = models.ForeignKey( ParentModel, related_name='children', on_delete=models.CASCADE ) created_by = models.ForeignKey(User, on_delete=models.CASCADE) class ParentSerializer(serializers.ModelSerializer): class Meta: model = ParentModel fields = ( 'name', 'children', ) class ChildSerializer(serializers.ModelSerializer): class Meta: models = ChildModel fields = ( 'name' ) class ParentViewSet(viewsets.ModelViewSet): serializer_class = ParentSerializer queryset = ParentModel.objects.all() class ChildViewSet(viewsets.ModelViewSet): serializer_class = ChildSerializer def get_queryset(self): user = self.request.user return ChildModel.objects.filter(created_by=user) I would like for ParentSerializer.children to only include the ChildModel objects with created_by as self.request.user. What is the correct way to filter ParentSerializer.children to the current user? I am open to changing the models as well. -
Create button to update in django posts with javascript fetch
I have an html that displays user's posts. At the same time, the post model is accessible via fetch (javascript). I want to create a button to update the content of the posts that django shows but with the fetch. The problem is that when the button is created in my code, instead of creating a button for each post, it creates 5 update buttons in the first post and it is logical because that is the id that I give it. How can I add a button to each of the posts that django shows with javascript? Note: the project its a test for the real project. I want to add a update button with javascritp in a django posts for update a field My html: <div id="formulario" class="form-style" style="border: 5px solid rgb(255, 170, 0);"> <h1>User's Posts</h1> {% for post in object_list %} <div id="posts-div" style="border: 5px solid red;"> <h3 id="user">{{post.usuario}} - User with id: {{post.id}}</h3> <h3>{{post.contenido}} - {{post.id}}</h3> </div> {% endfor %} <h1>Agregar</h1> <form method="post">{% csrf_token %} {{ form.as_p }} <input type="submit" value="Save"> </form> </div> My views.py class PostsViewSet (viewsets.ModelViewSet): queryset = Posts.objects.all() serializer_class = PostsSerializer class PostView(CreateView, ListView): model = Posts fields = ['contenido','edad','usuario'] template_name = 'api_app/posts.html' … -
How to use ColorThief with Django Rest Api?
I'm very beginner with coding. I want to get a dominant color from pictures. Color have to be saved and showed as a hex code. For now i have created simple code with picture name, width and height. I don't know how to implement ColorThief to this small project. In models file at the bottom i have created some code which i don't know how to run. Here are some of my files: Models: from django.db import models from colorthief import ColorThief class UploadImage(models.Model): name = models.CharField( 'Name', max_length=100, ) image = models.ImageField( 'Image', upload_to='uploaded_media/', width_field='width', height_field='height', ) height = models.PositiveIntegerField( 'Image Height', blank=True, null=True, ) width = models.PositiveIntegerField( 'Image Width', blank=True, null=True ) def __index__(self): color_thief = ColorThief(self.image) self.image = (color_thief.get_color(quality=1),) self.save() return f'#{self.image[0]:02x}{self.image[1]:02x}{self.image[2]:02x}' Viewsets: from rest_framework import viewsets from rest_imageupload.serializers import UploadImageSerializer from imageupload.models import UploadImage class UploadImageViewSet(viewsets.ModelViewSet): queryset = UploadImage.objects.all() serializer_class = UploadImageSerializer Serializers: from rest_framework import serializers from imageupload.models import UploadImage class UploadImageSerializer(serializers.ModelSerializer): class Meta: model = UploadImage fields = ('name', 'image', 'width', 'height') -
django-allauth messages not being displayed correctly
I'm using django-allauth in a project but unfortunately the messages on login and logout are not being displayed correctly. For example when I logout this message appears: <django.contrib.messages.storage.fallback.FallbackStorage object at 0x7f5b3f2c5e48> I've tried to reinstall Django and django-allauth but it hasn't fixed the problem. Any help/pointers much appreciated. -
One Wagtail API endpoint with different ViewSets
I'm using Wagtail API to set up a site with a single endpoint, but different Page types under that endpoint. In short, I have two models class TeamPage(Page) and class BlogPage(Page): and I want the following url paths GET /teams - TeamsAPIViewSet.listing_view to return a list of all TeamPages GET /teams/<slug> - TeamsAPIViewSet.detail_view to return the detail for a single TeamPage GET /teams/<slug>/blogs - BlogsAPIViewSet.listing_view to return a list of all BlogPages for a specific team GET /teams/<slug>/blogs - BlogsAPIViewSet.detail_view to return a specific BlogPage Registering the "teams" endpoint in api.py only allows a single ViewSet for that endpoint api_router.register_endpoint('teams', TeamsAPIViewSet) so, /api/teams will always use the TeamsAPIViewSet. I tried setting up paths in urls.py as follows: path('api/teams/', TeamsAPIViewSet.as_view({"get": "listing_view"}), name="listing"), path('api/teams/<slug:slug>/', TeamsAPIViewSet.as_view({'get': 'detail_view'})), path('api/teams/<slug:team_slug>/<slug:slug>', ContentAPIViewSet.as_view({'get': 'detail_view'})), path('api/teams/<slug:team_slug>/blogs/', BlogsAPIViewSet.as_view({'get': 'listing_view'})), path('api/teams/<slug:team_slug>/blogs/<slug:slug>/', BlogsAPIViewSet.as_view({'get' : 'detail_view'})), but that throws an exception, 'Request' object has no attribute 'wagtailapi_router' Any suggestions are appreciated. -
process remind to user on exact date and time in django
So I have notification system in place.For example when sending a task to user, user get a notification within my system. Right now I have only "instant" notifications. so when I send a task to someone, a notification is created in the db, and via web-socket the user is notified with the data of the notification. With the Reminder I have the problem, that the notification I want to send here is not necessarily "instant". I want to set the date to next Monday on 9 am. so User should receive the notification on Monday 9 am. Question: Is there an extension in django (or onboard methods) where I can execute stuff delayed? For example, send notification with the following data on Monday 9 am. -

Do null foreign keys slow things down?
I'm implementing file attachments for certain objects in the project I am working on. There are six or so object classes which might reasonably have attached files (which would be revealed in their Detail views and managed via a link from there). The model would be like class JobFile( models.Model): job = models.ForeignKey( 'jobs.Job', models.SET_NULL, null=True, blank=True, related_name='attachments', ) quote = models.ForeignKey( 'quotation.Quote', models.SET_NULL, null=True, blank=True, related_name='attachments', ) #etc document = models.FileField( ... ) # the attachment One advantage of this rather than a Generic ForeignKey is that an upload can be attached to more than one sort of object at once. Another is the simplicity of referring to obj.attachments.all() in the obj detail views. I'm not looking for a large set of object classes to which these files might be attached. However, for any one file attachment most of its ForeignKeys will be null. I have seen various references to null ForeignKeys causing slow Django ORM queries. Is this anything I need to be concerned about? If it makes any difference, these objects will be almost exclusively accessed via the attachments reverse ForeignKey manager on the related object. The only time I can see a need for explicit filtering … -

Why I got "http://~" as redirect url parameter althoguh I set "https://~" to LOGIN_REDIRECT_URL in mozilla-django-oidc?
I've been trying to integrate Django app with Keycloak using mozilla-django-oidc and fix the problem as refered to in the title. I configured LOGIN_REDIRECT_URL and the configurations that are required in settings.py LOGIN_REDIRECT_URL = "https://~" and prepared Django template. {% if request.user.is_authenticated %} \<p\>Current user: {{ request.user.email }}\</p\> \<form action="{{ url('oidc_logout') }}" method="post"\> {{ csrf_input }} \<input type="submit" value="logout"\> \</form\> {% else %} \<a href="{{ url('oidc_authentication_init') }}"\>Login\</a\> {% endif %} However I clicked the Login link, then I got the error message which says invalid redirect url because redirect url parameter was changed to http://~. I looked through the code of mozilla-django-oidc, and seemed that there's no function changing "https://~" to "http://~" as redirect url parameter and I set "https://~" to LOGIN_REDIRECT_URL so there might be something wrong with reverse proxy which is Istio in my case. I haven't configured anything by myself so far. In case of using Ngnix, this problem can be solved like this. I'd like you to answer what's the cause of problem and how to fix it. I appreciate for your time to read this. -

Rest API instead of table in Django Proxy unmanaged models
In my Django arch. task I must connect multiple projects. Some can only communicate through REST API and don't have common database access. However, the task is to provide seamless communication on model level. I.e. my model should serve as a wrapper for read requests in such a way, that business layer does not see the difference between local models and models that wrap remote data. Assuming that inherited create-delete-update methods will do nothing. I have read these: Proxy models documentation Unmanaged models documentation Also documentation on creation of custom managers and querysets. However, not a single good example for what I am set to achieve. Perhaps you can provide a solid Django example how to modify manager and query set in this way? -

Django, how to refresh html page not in urls.py only included with tags
I am working on an app that utilizes the {% include %} tags to build pages. Basically I have a layout.html that serves as the base and it has an include tag for the navbar.html and {% block content %} for other pages e.g. home, login, user etc. In the navbar.html there is another {% include %} for my notification.html which contains the badge icon for notifications. I am using django-notifications-hq to handle the notifications. Everything works, but to get new notifications, I have to refresh the page.

Dajngo admin: more "view on site" alternatives
I am creating a fairly standard CRUD application with Django. For now I have chosen an approach where the common/complex properties can be edited using custom forms and the more exotic elements of the application must be edited with the django admin - works quite nicely. In the Django admin I really like the "View on site" link which will take me to view an object on the site. Now I would really like to other "call back into the site" functionalities: From the list view in django admin I would like to be able to have a "View on site" which takes me to a "list view" in the application. From the application view in Django admin it would be nice to have a "View on site" which takes me to an "application root" in the application. Are any such things available?
