Django extra_views - UpdateWithInlinesView: field doesn't exist
I have two models: UserPost and Image - they are in one-to-many relationship. I want to be able to update both of the models in one template so I followed the docs and tried to implement UpdateWithInlinesView from extra_views but I got an error: Unknown field(s) (image) specified for UserPost Anyone knows what's happening? models.py class UserPost(models.Model): user_id=models.ForeignKey(User,on_delete=models.CASCADE) title=models.CharField(max_length=255) ...and some other fields class Image(models.Model): id = models.AutoField(primary_key=True) user_post=models.ForeignKey(UserPost,default=None, on_delete=models.CASCADE) image=models.ImageField(null=True,blank=True,upload_to='images/') def __str__(self): return self.user_post.title def get_absolute_url(self): return reverse('home') forms.py class ImageInline(InlineFormSetFactory): model = myModels.Image fields = ['user_post','image'] views.py class PostUpdate(UpdateWithInlinesView): model=shopModels.UserPost form=myForms.UploadPostForm inlines = [myForms.ImageInline] template_name = 'update_post.html' fields=['image'] def get_success_url(self): return redirect('home') update_post.html {% extends './base.html' %} {% block content %} {% csrf_token %} {{ form }} {% for formset in inlines %} {{ formset }} {% endfor %} {% endblock %} -
Django - CSRF cookie not set when logging in from Axios
I'm trying to use the standard Django authentication system with a separated Vue/Django app, so Vue handles entirely the entire frontend, Django will work as an API on the backend. Both backend and frontend will be deployed on the same server and on the same port, in order to keep Session auth. Right now my backend uses django-allauth (which uses the built-in Django auth under the hood, i think) for everything authentication related and it supports Session authentication from AJAX. I'm trying to login from the Vue SPA app using Axios, but i keep getting the following error: Forbidden (CSRF cookie not set.): /accounts/login/ Here is my frontend code: get_csrf() { axios.get('http://127.0.0.1:8000/get_csrf/') .then(response => { this.csrf_token = response['data']; }); }, authenticate() { this.get_csrf() axios.post('http://127.0.0.1:8000/accounts/login/', { username: 'test', password: 'test123', }, { headers: { 'X-CSRFTOKEN': this.csrf_token }, }) .then(function (response) { console.log(response) }.bind(this)) }, So get_csrf() is used to connect to an API endpoint on the Django backend that will generate the csrf token, i know that security wise this is not the best practice but i still have to find a safer way to use this, and i can also use samesite=Lax and disable the CSRF protection, but i don't … -
Multiple Django apps using django-tailwind
So, I have been trying out a way to use TailwindCSS with django and I luckily found the package that does the right job for me which is django-tailwind. In the docs, the author has specified how to use all the utlity classes of Tailwind in an app. But hasn't mentioned how to use Tailwind in other Django apps. TAILWIND_APP_NAME = <the app name> is the way to specify the Tailwind app So do I specify a list of the other apps I have like TAILWIND_APP_NAME = [<app1>, <app2>] Or some other way? Thanks. -
Update a field of a Django Object
I'm trying to update an object field in django. Usually I would do something like this: # MODEL --- class MyObj(models.model): name: models.CharField(max_length=10) surname: models.CharField(max_length=10) # VIEW --- # [...] myObj = MyObj.objects.get(pk=1) myObj.name = 'John' myObj.save() The problem is that the field to modify (in the example above: "name") is not known and passed as an argument to the post request. So I would have something like this: # VIEW --- # [...] field = self.request.query_params['field_to_modify'] myObj = MyObj.objects.get(pk=1) myObj[field] = 'John' myObj.save() now this triggers the error: myObj[field] = 'John' TypeError: 'MyObj' object does not support item assignment What is the correct way to update an "unknown" field of a django object? -
Different authentications and permissions in ModelViewSet - Django REST framework
This question is similar to this one: Using different authentication for different operations in ModelViewSet in Django REST framework, but it didn't work for me. I've got the following viewset: class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer queryset = UserProfile.objects.none() permission_classes = [SpecialPermission] SpecialPermission looks like this: class SpecialPermission(IsAuthenticated): def has_permission(self, request, view): if request.method == 'POST': return True return super().has_permission(request, view) REST framework settings: "DEFAULT_AUTHENTICATION_CLASSES": ["backend.api.authentication.ExpiringTokenAuthentication"], "DEFAULT_PERMISSION_CLASSES": ["rest_framework.permissions.IsAuthenticated"], I want to everybody to be able to post to UserViewSet but every other method should require Authentication. However, with the code above I get an Unauthorized Response on post. What do I need to change? -
Django not displaying image with correct settings
I'm trying to make a video/thumbnail model for displaying some videos. It shows the video and I can access the video file (FileField) in the browser, however, I get a 404 error for the thumbnail (ImageField). Since I can access the videos, I assume the media settings are working just fine. def get_video_upload_path(instance, filename): name, ext = filename.split('.') return os.path.join(f'videos/{instance.slug}.{ext}') def get_video_thumbnail_upload_path(instance, filename): name, ext = filename.split('.') return os.path.join(f'videos/thumbnail/{instance.slug}.{ext}') class Video(base_model): thumbnail = models.ImageField( blank=True, upload_to=get_video_thumbnail_upload_path) video = models.FileField( upload_to=get_video_upload_path) -

this is to filter a competition start date and end date in a the range provided by the user, below is the code that is working for the same but I want to supply field names (here:deadlines__start_date) and look_up types (here: __lte, __gte). and the user supplied range fields self.start_date and self.end_date. return qs.filter((Q(deadlines__start_date__gte=self.start_date) & Q(deadlines__end_date__lte=self.end_date)) |Q(deadlines__start_date__lte=self.start_date) & Q(deadlines__end_date__lte=self.end_date) & Q(deadlines__end_date__gte=self.start_date)) | (Q(deadlines__start_date__lte=self.start_date) & Q(deadlines__end_date__gte=self.end_date)) | (Q(deadlines__start_date__gte=self.start_date) & Q(deadlines__end_date__gte=self.end_date) & Q(deadlines__start_date__lte=self.end_date)) ) this was working fine but now I want to send field names and look_up types and values to be compared dynamically, but not finding any solution. ``` I tried doing it like below: kwargs0 = {str('%s__gte' % (start_field)) : str('%s' % self.start_date)} kwargs1 = {str('%s__lte' % (end_field)) : str('%s' % self.end_date)} kwargs2 = {str('%s__lte' % (start_field)) : str('%s' % self.start_date)} kwargs3 = {str('%s__lte' % (end_field)) : str('%s' % self.end_date)} kwargs4 = {str('%s__gte' % (end_field)) : str('%s' % self.start_date)} kwargs5 = {str('%s__lte' % (start_field)) : str('%s' % self.start_date)} kwargs6 = {str('%s__gte' % (end_field)) : str('%s' % self.end_date)} kwargs7 = {str('%s__gte' % (start_field)) : str('%s' % self.start_date)} kwargs8 = {str('%s__gte' % (end_field)) : str('%s' % self.end_date)} kwargs9 = {str('%s__lte' % (start_field)) : str('%s' % self.end_date)} q_object= Q() q_object.add(Q(**kwargs0), Q.AND) q_object.add(Q(**kwargs1), … -
How to sort events by date intervals Django REST
I'm working on a Django Rest project, building an API, and, since I got to the point to get all the events sorted by users, now I'm stuck on dividing those events by dates. For example, I want to sort between init_date and end_date, and be able to change the dates and display the events that occurred between those. -
How to take value from Django form?
I have a form with one field for choosing a method to sort objects. However, when I refer to this field to get it's value, it equals to HTML code that renders out this form. How do I solve this problem?

How to get subordinates, recursively?
I have Django models for Organizational Units (OrgUnit) which can be company, department, team, etc., ie. it is a tree structure: from django.db import models from django.contrib.auth.models import User from treebeard.mp_tree import MP_Node, MP_NodeManager class OrgUnit(MP_Node): # MP_Node adds a .path field name = models.CharField(max_length=120) Employees can be connected to one or more OrgUnits: class OUEmployee(models.Model): user = models.ForeignKey(User, related_name='employers', on_delete=models.CASCADE) orgunit = models.ForeignKey(OrgUnit, on_delete=models.CASCADE) ..and managers can manage several OrgUnits: class OUManager(models.Model): user = models.ForeignKey(User, related_name='+', on_delete=models.CASCADE) manages = models.ManyToManyField(OrgUnit, blank=True) Now I want a queryset of all employees that are subordinates of a given manager, implemented as a method on OUManager, however, the current implementation only gives the employees connected directly to the OrgUnits the manager manages, not to the child-orgunits: def subordinates(self): return OUEmployee.objects.filter( orgunit__in=self.manages.all() ) i.e. given: root = OrgUnit.add_root(name='Acme Corporation') dept = root.add_child(name='Dept. of Anvils and Tunnels') team = dept.add_child(name='QA') emp1 = OUEmployee(user=User.objects.create_user(username='emp1'), orgunit=team) emp2 = OUEmployee(user=User.objects.create_user(username='emp2'), orgunit=dept) mngr = OUManager(user=User.objects.create_user(username='manager')) mngr.manages.add(dept) I would like employees = mngr.subordinates() to return a queryset with both emp1 and emp2 (the above implementation only return emp2). Is there a way to write subordinates so it only requires one db-hit? The best method I have come up with so … -
CKeditor not working on CreateVIew in Django
I've installed CKeditor and apply it to the models.py. I run the migrations and migrate it to DB. I tried to test it by going to the admin page.

Getting Foreign Key data in Django Admin Add/Change Form
I am trying to customise the Django admin add/change for a project. I have created a model called "Visit" which contains 3 Foreign Key fields: "Customer", "Pet" and "Doctor". The workflow is as follows: The user creates a customer. The user creates a pet and associates it with a customer. The user creates a visit and associates it with a pet and a doctor. Below is the code for my models.py class Visit(models.Model): customer = models.ForeignKey('customer.Customer', on_delete=models.CASCADE) pet = models.ForeignKey('pet.Pet', on_delete=models.CASCADE) date = models.DateTimeField() doctor = models.ForeignKey( 'configuration.Doctor', on_delete=models.DO_NOTHING, null=True, blank=True) status = models.CharField( choices=PET_STATUS, max_length=3, null=True, blank=True) reason = models.CharField(max_length=255) diagnosis = models.TextField(null=True, blank=True) treatment = models.TextField(null=True, blank=True) comment = models.TextField(null=True, blank=True) prescription = models.TextField(null=True, blank=True) weight = models.DecimalField( max_digits=6, decimal_places=2, null=True, blank=True) class Meta: ordering = ('-date',) My issue is that someone using the Django Admin to create a Visit can wrongly choose a Customer and Pet. Hence, the Customer does not own that Pet. I would like to know how can I customise the Django Admin, so that, when the user selects a Customer, only Pets under that particular Customer is displayed in the dropbox. Below is my admin.py class VisitAdmin(admin.ModelAdmin): change_form_template = 'visit/invoice_button.html' add_form_template = 'visit/add_visit.html' … -

Try again." return render(request,"login.html", {"msg":message}) session_id=user['idToken'] request.session['uid']=str(session_id) return render(request,"pick.html") @login_required(login_url='login') def pick(request): return render_to_response('pick.html') pick.html {% load staticfiles %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <title>FYP - Is Your Network Safe?</title> <!-- Bootstrap core CSS --> <link href="{% static 'vendor/bootstrap/css/bootstrap.min.css' %}" rel="stylesheet"> <link href="{% static 'vendor/bootstrap/css/loader.css' %}" rel="stylesheet"> <!-- Custom fonts for this template --> <link href="{% static 'vendor/fontawesome-free/css/all.min.css' %}" rel="stylesheet"> <link href="https://fonts.googleapis.com/css?family=Varela+Round" rel="stylesheet"> <link href="https://fonts.googleapis.com/css?family=Nunito:200,200i,300,300i,400,400i,600,600i,700,700i,800,800i,900,900i" rel="stylesheet"> <!-- Custom styles for this template --> <link href="{% static 'css/grayscale.min.css' %}" rel="stylesheet"> <script src="https://api.mapbox.com/mapbox-gl-js/v1.11.1/mapbox-gl.js"></script> <link href="https://api.mapbox.com/mapbox-gl-js/v1.11.1/mapbox-gl.css" rel="stylesheet" /> </head> <body id="page-top"> <!-- Navigation --> <nav class="navbar navbar-expand-lg navbar-light fixed-top" id="mainNav"> <div class="container"> <a class="navbar-brand js-scroll-trigger" href="#page-top">TestPage</a> <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"> Menu <i class="fas fa-bars"></i> </button> <div class="collapse navbar-collapse" id="navbarResponsive"> <ul class="navbar-nav ml-auto"> <li class="nav-item"> <a class="nav-link js-scroll-trigger" href="{% url 'pick' %}">Home</a> </li> <li class="nav-item"> … -
Django i18n prefix_default_language=False can't redirect back to default language
I'm adding support for German on an English default site. I want the German version to add the /de/ prefix to all URLs as Django suggests but want to keep the standard URLs for the English version so it doesn't break the links I already have set up. The prefix_default_languge=False works as expected when you go directly to the URLs. The form that Django supplies switches to German correctly but doesn't allow you to switch back to the default language. This is only a problem with it set to False, When True the form works as expected (adding the /en/ prefix) and if I disable the i18n_patterns and just change the language without the URL changing the form also works. Why is this a problem just when prefix_default_language=False? urls.py: from django.conf.urls.i18n import i18n_patterns from django.contrib import admin from django.urls import include, path urlpatterns = [ path("admin/", admin.site.urls), path("staff/", include("stats.staff_urls")), path("i18n/", include("django.conf.urls.i18n")), ] urlpatterns += i18n_patterns( path("", include("stats.urls")), prefix_default_language=False, ) settings.py LANGUAGE_CODE = 'en' LOCALE_PATHS = ( os.path.join(BASE_DIR, 'locale'), ) LANGUAGES = ( ('en', 'English'), ('de', 'German'), ) TIME_ZONE = 'Europe/London' USE_I18N = True USE_L10N = True USE_TZ = True form.html {% load i18n %} {% get_current_language as LANGUAGE_CODE %} <form … -
Sorting serialized data - Django - getting keyerror
Version Info: Django: 1.11.2 Python 2.7 In my application, I want to sort by a field in the data that is returned by the serializer, however, it is throwing an error. The resultset is of type rest_framework.utils.serializer_helpers.ReturnList, the data is given below (only sample, actual data is pretty huge). [OrderedDict([(u'id', 941), ('business_location', {'distance': 3.7249839781687317, 'business': 941, u'id': 916}), ('business_detail', {'business_profile': u"Good solutions!", 'website': None}), ('business_images', []), ('business_service', [OrderedDict([(u'id', 1587), ('length_of_slots', 12), ('price', 25.0), ('business_group', None)])])]), OrderedDict([(u'id', 1595), ('business_location', {'distance': 6.376269428282773, 'business': 1595, u'id': 1634}), ('business_detail', {'business_profile': u'A long-term wellness.', 'website': None}), ('business_images', []), ('business_service', [OrderedDict([(u'id', 5361), ('length_of_booking_slot', u''), ('price', 125.0), ('business_group', None)])])])] The error I'm getting is (KeyError('price',), 'price') The views.py, I'm using this code to sort by price. sorted(business_serializer.data, key=lambda k: (k['price'])) Kindly suggest what is that I'm doing wrong. Also, I would want to implement ASC/DESC functionality. Note: I tried to implement order_by in the serializer, since my data has a different category & each of them will have a price it is not getting sorted at the result level.
