Django return redirect to external url not working
I'm having difficulty getting a redirect to work for external URLs. The following is in the views.py file: def link_out(request): products = products_for_cart(user=request.user) product = get_object_or_404(products, pk=product_id) if product.is_link(): variant_id = request.POST.get('variant') variant = ProductVariant.objects.get(id = variant_id) print(variant.external_url) response = redirect(variant.external_url) print('before redirect') return response print('after redirect') 'before redirect' and the URL are printed in the shell, however, the browser never redirects to an external URL. https://www.google.co.uk/ before redirect INFO django.server "POST /en/products/t-shirt-6/add/ HTTP/1.1" 302 0 [PID:31664:Thread-3] INFO django.server "POST /en/products/t-shirt-6/add/ HTTP/1.1" 302 0 [PID:31664:Thread-3] INFO django.server "POST /en/products/t-shirt-6/add/ HTTP/1.1" 302 0 [PID:31664:Thread-3] There are two things that seem interesting to me, the three POSTs after the redirect (all INFO prints are coming in threes??), and that the redirect isn't executing in the browser. My questions are, where does the redirect get returned to from the views.py file, and what could be the reason for the broswer not redirecting? Thanks -
CORS blocked in dockerized Django REST + Angular project
I decided to dockerize an existing Django REST + Angular app today. The website is displaying as it should, however CORS requests are being blocked. Access to XMLHttpRequest at 'http://localhost:8000/branches/1' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. The angular App is dockerized using Nginx. I was using this tutorial in the progress (docker + compose files are listed below). Strange thing about this is that I had this problem before and solved it through the use of the djang-cors-headers package. Along with CORS_ORIGIN_ALLOW_ALL = True, this no longer seems to be solving the issue. Can this be related due to the fact that the application now runs in containers? I'm providing the dockerfiles for the projects along with the docker-compose file below. Not sure if they are relevant though. Dockerfile for the Angular project: FROM tiangolo/node-frontend:10 as build-stage WORKDIR /app COPY package*.json /app/ RUN npm install COPY ./ /app/ ARG configuration=production RUN npm run build -- --output-path=./dist/out --configuration $configuration # Stage 1, based on Nginx, to have only the compiled app, ready for production with Nginx FROM nginx:1.15 COPY --from=build-stage /app/dist/out/ /usr/share/nginx/html # Copy the default nginx.conf provided by … -
Django Rest Framework - Restrict FK entries
I have 2 models, Post and Comments class Post(models.Model): post_id = models.IntegerField(primary_key=True) ... class Comment(models.Model): post = models.ForeignField(Post, on_delete=models.CASCADE, related_name='comment_post') ... I have made a serializer for post class CommentSerializer(serializers.ModelSerializer): class Meta: model = Comment fields = '__all___' class PostSerializer(serializers.ModelSerializer): comments = CommentSerializer(many=True, source='comment_post') class Meta: model = Post fields = ('post_id', 'comments') The PostSerializer gives all the comments on a particular post. I want to access 5 latest comments per post. (planning to use something like order_by('-comment_time')[:5]) How can i do this in Django Rest Framework within PostSerializer? Thanks! -
How add extra fields data to database with UserCreationForm Django?
I'm trying to add data from UserCreationForm extra fields to database, i want to add multiple fields to UserCreationForm and save it to database. I saw other examples from topics here in stackoverflow, but it doesn't work. Here is a example of my code: ( fields: "agree_terms" or "price" could be anything else) forms.py from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm class UserRegisterForm(UserCreationForm): email = forms.EmailField(widget = forms.EmailInput(attrs= {'placeholder':'Email'})) agree_terms = forms.BooleanField() price = forms.DecimalField(decimal_places=2, max_digits=10000) class Meta(UserCreationForm.Meta): model = User fields = UserCreationForm.Meta.fields + ('username', 'password1', 'email','password2','agree_terms','price') views.py @csrf_protect def registers(request): if request.method == 'POST': form = UserRegisterForm(request.POST) print(form) print(form.is_valid()) if form.is_valid(): form.save() username = form.cleaned_data.get('username') messages.success(request,'Conta criada {}'.format(username)) return redirect('login') else: form = UserRegisterForm() return render(request,'header-login.html',{'form':form}) -
writing unit test for many to many model in django program
in my django projects, I have a two class like following: class DataTag(models.Model): title = models.CharField(max_length=120, unique=True) relations = models.ManyToManyField('DataTag', related_name='related_data_tags', blank=True) and the another class is: class Data(models.Model): tags = models.ManyToManyField('DataTag',related_name = 'data') def tag_name(self): if self.tags.all(): return self.tags.all()[0].title return '' both my models work, but now I want to write a test for main_tag_name, and checking if this function returns a true value or not.until now I write the following: from unittest import TestCase class BusinessTest(TestCase): def test_tag_name(self): self.data = Data.objects.create() self.tag1 = DataTag.objects.create() I am new on writing test. please help me for writing this test.

Django template variable (model instance) translation
There is a Product model with name CharField in my db. There is a template for rendering one instance of the Product model on the page. In view i'm passing to the template product variable which is filtered instance of the Product model. In template i need to translate variable {{ product.name }} depending on which Product instances page is rendering now. After reading Django documentation: To translate a template expression – say, accessing object attributes or using template filters – you need to bind the expression to a local variable for use within the translation block. i decided to use next: {% blocktrans with product_name=product.name%}{{product_name}}{% endblocktrans %} in django.po file i get: msgid "%(product_name)s" Can you tell me please, am i on the right way? And how should name attributes of the other product instances be translated if such approach allows to provide translation only for one product.name? Thanks for any attention! -
Formatting DateTimeField in Django
When saving timestamp in Django's DateTimeField using auto_now_add this way: creation_timestamp = models.DateTimeField(auto_now_add=True) the field is saved with miliseconds: 2018-11-20T15:58:44.767594-06:00 I want to format this to be displayed without miliseconds: 2018-11-20T15:58:44-06:00 But the only option I could come up with does not exactly shows what I need: format="%Y.%m.%dT%H:%M:%S%z" gives me 2018.11.20T15:58:44-0600 How do I format this field the way I need? Alternatively I'd rather save DateTimeField without milliseconds at all but does auto_now_add allow to do this sort of thing? -
jQuery not sending element text to form field [duplicate]
This question already has an answer here: Event binding on dynamically created elements? 23 answers I created a set of links in jQuery. The "zip_list" below is from an ajax call that got the data from a Django database request. This part works as expected, at least I think... //end of ajax call that gives json response dataType: "json", success: function(data) { zip_list = JSON.parse(data); //parse json response x = zip_list.length; //get length value for loop var container = $('<div />'); for(j=0; j<x; j++){ container.append($('<a href="#">').addClass("zip_response").text(zip_list[j]["city"]+','+zip_list[j]["state"])); container.append($('<br>')); } $('.zip_menu').append(container); } It outputs html code that looks like this: <div class="zip_menu"> <div> <a href="#" class="zip_response">COLUMBIA,MO</a> <br> <a href="#" class="zip_response">HINTON,MO</a> <br> <a href="#" class="zip_response">LINDBERGH,MO</a> <br> </div> </div> Now with those links, when they are clicked should fill in form data, with the below jQuery: $(".zip_response").click(function () { var txt = $(this).text(); //****NOT WORKING ON ELEMENTS CREATED THROUGH JQUERY, BUT WORKS ON SAME LINKS IF PUT IN AS NORMAL HTML var city_state = txt.split(","); //splits that text that in the tag, but a comma producing an array, with the city and state console.log(city_state[1]); $("#state").val(city_state[1]); //form field for state $("#city").val(city_state[0]); //form field for city }); The issue is that at this point in the … -

Is the default django development server secure or can others access it?

Only allow requests from single site in Django Rest Framework
For illustrative purposes let's say I have a website at https://www.signup.com that let's users sign up for an email list. After the user enters their email and hits 'Submit,' signup.com sends POST request to https://www.manager.com: { "email" : "fake@whatever.com" } Then the server adds that email to the database. My question is: what's the best way to ensure that only signup.com is able to successfully send POST requests to manager.com? -

How to create another column with filtered value in queryset

using css/ bootstrap webtabs for django forms
I run into the following issue with my Django project: I have an profile edit page, where I want the user to be able to edit their profile information, which is seperated in tabs that they can navigate: Profile and Extended Information. However, the page loads at the Profile tab, but when I navigate to the Extended Information tab, it just opens this tab below the Profile tab, and it doesn't 'replace' the first tab with the second. Consequently, I get a MultiValueDictKeyError error when I only change something in the Extended Information form under that tab. How do I fix the error with the tabs opening below each other? I suspect that my MultiValueDictKeyError also disappears then (but I'm not sure).

Parsing json returned in django modelformset in template
One of the fields returned to my template in a formset generated by modelformset_factory() is a JSONField. I'd like to parse the json and display elements in it separately within the form, read-only.

But it has to be in a form that has some added fields for users to fill. {% for foo in foo_list %} <h5>{{ foo.json|get:"title" }}</h5> {% endfor %} The problem is that doing the same for a formset field I get the error "'BoundField' object has no attribute 'get'" {% for form in formset %} <h5>{{ form.json|get:"title" }}</h5> {% endfor %} Here is the filter: @register.filter(name='get') def get(d, k): print('get(d,k):',d,k) return d.get(k, None) The relevant bits of the view: ... foo_list = Foo.objects.all() ...

Django, Docker, and Pipenv - Error adding new packages
Using Pipenv with Docker is causing some issues in my Django project. I've installed Django locally with Pipenv which generates a Pipfile and Pipfile.lock. Then used startproject to start a new Django project.

What causes the error "Invalid password format or unknown hashing algorithm."?
I see a lot of answers as to how to solve this issue, but I'd like to know what exactly causes this? I have a random password generator that generates a random sequence consisting of uppercase letters, lowercase letters and numbers like this: min_char = 10 max_char = 12 allchar = string.ascii_letters + string.digits genpassword = "".join(choice(allchar) for x in range(randint(min_char, max_char))) This causes the "Invalid password" error and I'd like to know why.
