Django. How to implement a logic to initiate a delete time counter or countdown in django models to delete objects automatically?
Hello guys how can I implement a logic in django to delete a coupon automatically after 2 days from the time the user has opted to delete his post.? I have this view which has the normal delete function. but how to make changes in this to have this deleted automatically after 2 or 3 days from the database and not immediately.? view class DeletePostView(LoginRequiredMixin, UserPassesTestMixin, BSModalDeleteView): model = Post template_name = 'posts/delete_post.html' success_message = 'Deleted' def get_success_url(self): return reverse_lazy('posts:myhome') def test_func(self): post = self.get_object() if self.request.user == post.user: return True return False If its difficult to implement in class based view, please do let me know how to implement that logic with fbv.

Images not showing when running for loop to fetch images
I have a for loop in my index.html file to dynamically fetch images from the images folder for three objects. But it is only fetching the first image, with that missing image icon showing on the server for the other two 'destination' objects. Is there anything standing out as amiss in the index.html and views.py files? All three images were showing when they were hardcoded and are all present in the images folder. It's since I introduced the {% static "images" as baseUrl %} and the for loop that it doesn't work. It's just odd that it does indeed load the first image, but not image 2 and image 3. Here is the for loop code with the top imports in index.html: {% load static %} {% static "images" as baseUrl %} {% for dest in dests %} <!-- Destination --> <div class="destination item"> <div class="destination_image"> <img src="{{baseUrl}}/{{dest.img}}" alt=""> <div class="spec_offer text-center"><a href="#">Special Offer</a></div> </div> <div class="destination_content"> <div class="destination_title"><a href="destinations.html">{{dest.name}}</a></div> <div class="destination_subtitle"><p>{{dest.desc}}</p></div> <div class="destination_price">From ${{dest.price}}</div> </div> </div> {% endfor %} In my views.py file: from django.shortcuts import render from .models import Destination def index(request): dest1 = Destination() dest1.name = 'New York' dest1.desc = 'City that never sleeps' dest1.img = 'destination_1.jpg' … -
AsserrtTemplateUsed fails despite template being used...?
I have a view: class DashboardView(TemplateView): template_name = "dashboard/dashboard.html" Which I am testing using TestCase: class TestAuthorisedViews(TestCase): @classmethod def setUpTestData(cls): cls.client = Client() cls.response = cls.client.get(cls.url) def test_view_uses_correct_template(self): print('template', self.response.__dict__) self.assertTemplateUsed(self.response, 'dashboard/dashboard.html') This test fails with AssertionError: No templates used to render the response. However, the print() debug I included in the test reveals the response does use a template: template {'template_name': ['dashboard/dashboard.html'], 'context_data': { 'view': <dashboard.views.DashboardView object at 0x0000019E9CF33040> }, // etc >} Am I using this test correctly? When looking at the source code, it seems the error fails because response.templates = [] rather than response.templates = None. -

Django AbstracUser with multiple profiles
I'm having a given below models.py structure: from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin from django.db import models class User(AbstractBaseUser, PermissionsMixin): USERNAME_FIELD = "email" email = models.EmailField(verbose_name="E-mail", unique=True) def __str__(self): return self.email class Profile(models.Model): phone_number = models.CharField(verbose_name="Phone number", max_length=15) def __str__(self): return self.phone_number class Meta: abstract = True class UserProfile(Profile): user = models.ForeignKey(to=User, on_delete=models.PROTECT, related_name="profile") group = models.CharField( verbose_name="Group type", choices=GroupChoices.choices(), # Group1, Group2 etc. max_length=20 ) def __str__(self): return self.user class Meta: unique_together = ("user", "group") I'd like to have a possibility to create users with the same email & phone number. The only difference would be a membership to different groups. The code below seems to be working properly, but once there are two users with the same email(which makes user instance unique), it always returns a list of profiles, instead of returning the specific user profile. One of the concerns is when accessing another model where User model is in a relation by FK. Then it returns a list of profiles, instead of the specific one. To compare, using Uber app you can be both a passenger & driver (the same email and the same phone number, but different profiles) - I'm trying to achieve something similar. Is this … -

IntegrityError: update or delete on table "products_product" violates foreign key constraint

ImageField is not uploading to specified directory
I have been googling this for an ours and can't find the solution. When I use admin panel, image is loading to the directory that is needed. But when I create post from the fronend, the image is just loading to the main directory, wich is media. I now that I it will work if I use django forms and createview, but I need adding a post with a function like I did. I think this problem might happen, because ImageField needs validating. But I don't know how to validate it outside the django forms context. Any help appreciated. I have model Posts with ImageField image and upload_to option: class Posts(models.Model): image = models.ImageField(upload_to="posts/%Y/%m/%d", null=True,blank=True) then in views.py the function, that adds new post: @login_required def add_post(request): if request.method == 'POST': title = request.POST.get('title') content = request.POST.get('content') upload_file = request.FILES['image'] fs = FileSystemStorage() image = fs.save(upload_file.name, upload_file) post = Posts(title=title, content=content, image= image) post.author = request.user post.save() from django.http import HttpResponseRedirect #return redirect(post.get_absolute_url()) return HttpResponseRedirect(request.META.get('HTTP_REFERER')) return render(request ,'users/user-detail2.html') and the wich displays the form: <form action="{% url 'add_post' %}" method="post" enctype="multipart/form-data"> {% csrf_token %} <div class="modal-header"> <h5 class="modal-title">Share Your Mood</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div … -
How to use a Many-to-Many through model in DRF
So I'm trying to achieve the general "Like" functionality in a social media website using Django and REST Framework, and a frontend in React. Using a Post model to save all the posts, and I have a Many-to-Many field for storing the likes and created a through model as follows: class PostLike(models.Model): user = models.ForeignKey(AppUser, on_delete=models.CASCADE) post = models.ForeignKey("Post", on_delete=models.CASCADE) timestamp = models.DateTimeField(auto_now_add=True) class Post(models.Model): user = models.ForeignKey(AppUser, on_delete=models.CASCADE) caption = models.TextField() created_at = models.DateTimeField(auto_now_add=True) edited_at = models.DateTimeField(auto_now=True) likes = models.ManyToManyField( AppUser, related_name="post_user", blank=True, through=PostLike ) (AppUser is a custom auth model used) Similarly, I have created serializers and viewsets for the above models: class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = "__all__" class PostLikeSerializer(serializers.ModelSerializer): class Meta: model = PostLike fields = "__all__" class PostViewSet(viewsets.ModelViewSet): queryset = Post.objects.all() serializer_class = PostSerializer class PostLikeViewSet(viewsets.ModelViewSet): queryset = PostLike.objects.all() serializer_class = PostLikeSerializer My question is, how do I "like" or remove an existing "like" from a post using API calls? One method I know is to just make a POST request to the PostLike endpoint using the user PK and the post PK to create a PostLike instance, but I don't know a way to "remove" a like using the same method. … -

Is it possible to stream JSON in Django with StreamingHTTPResponse or in any other way?
I'm wondering if it's possible to correctly stream JSON in Django? I've tried to use StreamingHTTPResponse but what I'm sending is incorrect JSON format - expected [json], sending [json][json]..[json], each is separate array. I kind of understand the idea - we cannot send [json ... json... json] because it will be incomplete on all iterations but last (it's important to close the array bracket). But maybe I'm wrong. Please help me to understand how JSON can be streamed correctly. According to documentation StreamingHTTPResponse mostly used for csv, but nowhere is it said that it cannot be used for JSON. If that's the case, how to make it work? Would really appreciate any help, I'm trying to solve this mystery for a few days now. def generator_chunk(): ... yield df.to_json # returns data like [json] @api_view(['GET']) def return_data(request): ... return StreamHttpResponse(generator_chunk) # streams data like [json][json], which is not proper json format Similar questions (which have no answer): Proper way of streaming JSON with Django django stream a dictionary multiple times w/o breaking JSON -

initdb: error: could not create directory “./PostgreSQL”: Permission denied
It is my first time setting up a database (postgresql 12) on my windows 8.1 It's been 4 days of struggling to find a solution from many related questions in this field but not successful to find the answer (whether I didn't understand them or they didn't work in my case). So, here, I will explain, step by step, what I did and what errors I got in each phase (They may not affect each other but I mention all the errors): When I installed PostgreSQL, at the end of the process I got this error: "Failed to load SQL modules into the database cluster" I reinstalled twice but it seemed to pop up every time. Here, in this post, I found somebody who faced the same problem, but I didn't technically understand what is the solution, unfortunately: Failed to load sql modules into the database cluster during PostgreSQL Installation. thus, I just skipped it and everything seemed okay. Then I set the PATH in advanced system settings-->Environment variables (in both user variables and system variables boxes) like this: ";C:\Program Files\PostgreSQL\12\bin;C:\Program Files\PostgreSQL\12\lib" After this step, I opened a terminal using ctrl+R and entered cmd.exe then entered these codes: > cd … -

Does anybody know why my forms aren't being rendered? -
