Why are my django modelformsets being prepopulated after user uploads data?
So, I have a django modelformset for allowing the user to upload multiple listings on a fake ecommerce site. When the user first accesses the "upload page" the forms are clear and there's no problem. After the user uploads some items, though, it seems like django is prepopulating the forms with the information the user submitted earlier. I don't want this, and I have no clue how to prevent it. Here is the forms.py: class ProductModelForm(forms.ModelForm): class Meta: model = Product fields = [ "product_name", "product_description", "product_price", ] class ProductImageModelForm(forms.ModelForm): class Meta: model = ProductImage fields = [ "product_image", ] ProductModelFormSet = modelformset_factory( Product, fields=( "product_name", "product_description", "product_price", ), extra=3, ) ProductImageModelFormSet = modelformset_factory( ProductImage, fields=( "product_image", ), extra=3, ) and here's the view that handles it: @login_required def product_upload_view(request): if request.method == "POST": product_form_set = ProductModelFormSet(request.POST) product_image_form_set = ProductImageModelFormSet(request.POST, request.FILES) if (product_form_set.is_valid() and product_image_form_set.is_valid()): for obj, obj_image in zip(product_form_set.save(commit=False), product_image_form_set.save(commit=False)): obj.product_seller = request.user obj.product_pub_date = timezone.now() obj.product_image = obj_image obj_image.save() obj.save() return HttpResponseRedirect("somewhere/else/") product_form_set = ProductModelFormSet() product_image_form_set = ProductImageModelFormSet() return render(request, "products/upload.html", { "product_form_set": product_form_set, "product_image_form_set": product_image_form_set, }) Now, I don't know if I'm even explaining my problem right because I can't seem to find an answer online but … -
Why is Django rendering one of my app's templates as plain text
I am working on a blog development in Django and there are different categories of posts or articles on category_list.html which have been created using ORM library and to each category i have added some articles using ORM library with the help of category slug which are rendered on category_view.html and problem is that list of categories are shown perfectly on category_list.html after adding from admin panel of django and when I click on any category name(contains get_absolute_url link), it takes me perfectly to category_view.html page but on category_view.html, data is shown in the form of text means renders the complete content of category_view.html in the form of plain text. All other templates are getting rendered by django perfectly but what is the reason that category_view.html is getting rendered as plain text? Please help me def category_list(request,category_slug=None): category=None categories=CategoryList.objects.all() # article=Article.objects.all() return render(request,'category_list.html',{'categories':categories}) def category_view(request,category_slug): category=get_object_or_404(CategoryList,slug=category_slug) article=Article.objects.filter(category=category) return render(request,'category_view.html',{'category':category},{'article':article}) My url.py contains the following urls: path("",views.index), path('category',views.category_list, name='category_list'), path('<slug:category_slug>',views.category_view, name='story_by_category'), This is link in category_list.html which takes me to category_view.html <div class="row py-3"> {%for c in categories%} <div class="col-lg col-12 homeimg" id="img1"> <h5><a href="{{c.get_absolute_url}}">{{c.name}}</a></h5> <img class="secimg border-info" src="{{c.image_url|default_if_none:'#'}}" alt="gameplay videos"> </div> {%endfor%} </div> -

Django using Celery not performing my task
I have been trying for the past 3 days to get django to perfom asynchronous tasks on a periodic schedule. Came across Celery which seemed like a perfect match for my problem but the more I read online the more problems there seemed to exist that I had prepared. Anyway I was able to vaguely glue up together pieces of information to finally come up with a "somewhat solution" because there were so many deprecated modules and methods it was hard to find a working example from start to finish. So I am trying to create a task which will create a certain model object periodically (let's say 30 seconds for sake of the argument). So I installed redis as the "broker", (so I saw fit in other discussions) and managed to set up my task up and running but the problem is that even when it executes, no new model is created, I suspect that it might be cause of maybe a misconfiguration between the local and the settings time-zone but frankly I'm not sure, supposedly it should be able to create new instance when run through django-celery-beat tables in the admin panel my init.py: from __future__ import absolute_import, … -
Failure to authenticate User with AuthenticationForm
I'm attempting to create a TemplateView where each subclass renders an AuthenticationForm; subclassing it and naming it UserLoginForm. This gives the User the opportunity to login with their credentials on any page they visit and be redirected to that same page after being successfully authenticated. When validating UserLoginForm, it fails to authenticate when it reaches form.clean() and raises self.get_invalid_login_error(). The TestCase used to simulate this scenario creates a User, then a POST request with the same credentials is sent. What's causing the UserLoginForm to invalidate the data passed to it and not finding the User? https://github.com/django/django/blob/main/django/contrib/auth/forms.py#L197 class TestTopicListMainPage__003(TestCase): '''Verify that an anonymous user is logged into their User account''' @classmethod def setUpTestData(cls): user = User.objects.create_user("User", 'secretcode') cls.data = { 'username': "User", 'password': "secretcode" } def test_topics_listing_login_user(self): response = self.client.post( reverse("topics:listing"), data=self.data ) self.assertEqual(response.status_code, 200) self.assertTemplateUsed(response, "topics/listing.html") self.assertContains(response, "Logout") class AbstractListingView(TemplateView): template_name = "topics/listing.html" def get_context_data(self): context = super().get_context_data() context['topics'] = Topic.objects.all() context['search_form'] = SearchForm() context['login_form'] = UserLoginForm return context def post(self, request): context = self.get_context_data() form = context['login_form'](request, data=request.POST) if form.is_valid(): resolver = resolve(request.path) login(request, form.user_cache) return HttpResponseRedirect(reverse(resolver.url_name)) return self.render_to_response(context) class TopicsMainPage(AbstractListingView): extra_content = { 'heading': 'Questions', 'query_links': ['interesting', 'hot', 'week', 'month'] } def get(self, request): query = request.GET.get('tab', None) … -
Django doesn't create test database when running test
I read in Django document that a blank database will be created for testing. I am new to Django so I barely changed anything in setting.py and currently using Sqlite database. However, when I run python manage.py test, Django keep telling the user has been existed, so I tried changing the username for the created users in TestCase, run the test again and found out that the new users are created in the existing database. The test file is as bellow: class UserTestCase(unittest.TestCase): def setUp(self): admin = User.objects.create(username="admin", password="1") user1 = User.objects.create(username="user1", password="1") user2 = User.objects.create(username="user2", password="1") admin.following.add(user1) admin.followers.add(user2) def test_users_count(self): self.assertEqual(User.objects.count()==3) My model is as bellow: class User(AbstractUser): followers = models.ManyToManyField('self', related_name="following", symmetrical=False, through='Follow', through_fields=('followee', 'follower')) def __str__(self): return f"{self.username}" def serialize(self): return { "id": self.id, "username": self.username, } class Follow(models.Model): followee = models.ForeignKey( 'User', on_delete=models.CASCADE, related_name='+' ) follower = models.ForeignKey( 'User', on_delete=models.CASCADE, related_name='+' ) def clean(self, *args, **kwargs): if self.follower__id == self.followee__id: raise ValidationError('Can not follow self.') return super().clean(*args, **kwargs) class Meta: constraints = [ models.UniqueConstraint(fields=['follower', 'followee'], name='follow_once'), models.CheckConstraint(check=~Q(follower=F('followee')), name='not_follow_self') ] -

How do I check if another user is being followed by another user?
So I have a UserProfile Model with a relationships field which defines relationships between two users class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, default=None , null= True) relationships = models.ManyToManyField('self', through='Relationship', symmetrical=False, related_name='related_to') and a Relationship table class Relationship(models.Model): from_person = models.ForeignKey(UserProfile,on_delete=models.CASCADE,related_name='from_people') to_person = models.ForeignKey(UserProfile,on_delete=models.CASCADE,related_name='to_people') status = models.IntegerField(choices=RELATIONSHIP_STATUSES) Case example: Let's say I have a UserProfile(1) object and I need to access it's relationship field to determine if another UserProfile(2) has a relationship with UserProfile(1), how do I write such a query? I have seen code like: rel = UserProfile1.relationships.filter( to_people__from_person=UserProfile1) return rel.filter(pk = UserProfile2.id).exists() But I do not understand the code below. Does this return a Relationship object or UserProfile object? I am guessing to_people is for the reverse access to Relationship from UserProfile object but I don't understand how it's been done. Docs tell me the filtering is done based on field__lookuptype=value but I don't get it wrt the code below. Can someone shed more light on this?

Why is django not creating a database table with 'migrate' command
I am new to Django, and for some odd reason my models are not creating a database table and am completely clueless as to why. When I run the command: "python manage.py makemigrations" I get the following shows up int he console output: Migrations for 'auctions': auctions/migrations/0001_initial.py - Create model User - Create model Item Which appears to be accurate to me. So then I run the command: "python manage.py migrate" and the following shows up in the console output. Operations to perform: Apply all migrations: accounts, admin, auctions, auth, contenttypes, sessions Running migrations: No migrations to apply. Looking into the database and sure enough nothing was created.

Authenticate a user login based on face encodings stored on database?
I am working on a face-login project where a user can submit his images using a webcam during the registration and login to the website using a live camera feed. The problem I am facing currently is submitting the snapshot stored on the HTML canvas a form "response" and storing the face-encoding or the entire image for now to the database associated with this user. I have successfully created a Registration / Login page that authenticates based on the Username and the Password for now. I made this using the 'User' model imported from django.contrib.auth.models. I read a bit about OneToOne models but it says not to be used for Authorization and I specifically need it for Authorizing the login. On the Registration page, I have added a section where a user can click a button and take a snapshot. The problem is How do I submit this image as a part of the form? Store this base64 image to the Database which I will retrieve later for Authentication. Any hints on how to proceed would be great! I tried modyfing the User model to have an extra face_data field but it doesn't work. Views.py from django.shortcuts import render, HttpResponse, … -
Django Admin Page show model referencing to another model as choose list
I already created a new database instance called StatusList: class StatusList(models.Model): status_text = models.CharField(max_length=300) color = ColorField(default='#ff0000') def __str__(self): return self.status_text I also created some entries like: "Shop closed; red color", "Shop open; green color", etc... This is supposed to show up, when calling the Homepage and show the status with the associated color. Therefore, I would like to choose (drop-down list in Admin Page) one entry provided by StatusList. I thought about a second model called "StatusChoosen", but does it make sense? It is an instance with just one entry representiong the one choosen by an admin. Even in this case I don't know how to show all entries from StatusList and return the active one. I would appreciate your help. -
Problem with CKEDITOR attachments integrated in Django contact mail form
I integrated ckeditor in my contacts form-email following the instructions provided by the official documentation and it works correctly. My problem is the following (both locally and in production): when I attach an image or an attachment (via ckeditor uploader) and send the email from the form, I receive an email in which the image is not visible and the attachment is not downloadable. By copying the link of the image or attachment, the path is shown and not the url .. I think this is the problem. Don't know how to fix it? Anyone have any ideas? Thank you in advance!!! Below is the code I used: settings.py STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), os.path.join(BASE_DIR, 'core/static'), os.path.join(BASE_DIR, 'appForum/static'), os.path.join(BASE_DIR, 'appEventi/static') ] STATIC_URL = '/static/' STATIC_ROOT = "/home/django/static-serve" MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'media-serve') MEDIA_URL = '/media/' CKEDITOR_JQUERY_URL = 'https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js' CKEDITOR_UPLOAD_PATH = 'ckeditor_uploads' CKEDITOR_IMAGE_BACKEND = "pillow" CKEDITOR_BROWSE_SHOW_DIRS = True CKEDITOR_CONFIGS = { 'toolbar_custom': { 'toolbar': 'Custom', 'skin': 'moono-lisa', 'width': 'auto', 'toolbar_Custom': [ ['Bold', 'Italic', 'Underline'], ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock'], ['Link', 'Unlink'], ['RemoveFormat', 'Source',], {'name': 'insert', 'items': ['Image', 'Update', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar']}, {'name': 'extra', 'items': ['CodeSnippet']}, ], }, } models.py from ckeditor_uploader.fields import RichTextUploadingField # Create your … -
How to write save Postgresql query in Django
In my Django project I have SQL query like this: `..." WHERE column1 LIKE %s", query + " OR column2 LIKE %s", query...` I read that using the %s" is good practice because it prevents SQL injection, but when i run this I get an error like `can only concatenate tuple (not "str") to tuple`. How to write this query properly and avoid SQL injection? (Disclaimer: I know that ORM is fantastic, but I HAVE TO use raw query) -

Django ./manage.py test is failing
I've created a migration file with 3 RunSQL operations. First operation is to drop a column and other two operations are to delete table data and the migration file is working fine. But ./manage.py test is failing with the below error. django.db.utils.ProgrammingError: column xxx does not exist. I can see the column is dropped in test_##app## db, but it is trying to drop column again. I can also see the migration file entry in django_migrations. Is there a way to check if the column is available or not before executing the ALTER operation in migration file? -
