Granting a user access to view data based on their permissions
I have a basic CRUD web application in Django using a database with Postgres 12 that simply displays articles based on a search. I need to implement a system such that the articles returned from a user's search are articles that the user only has access to. For example, if my articles table article is populated id|title|summary|source |category --+-----+-------+--------+-------- 0 |... |... |NYTimes |politics 1 |... |... |BBC |environment 2 |... |... |BBC |politics 3 |... |... |Wired |technology 4 |... |... |NYTimes |fashion If a user makes a search, but only was granted access to view sources NYTimes and BBC as well as only categories politics, then the the user would only see id|title|summary|source |category --+-----+-------+--------+-------- 0 |... |... |NYTimes |politics 2 |... |... |BBC |politics Right now I implemented this schema. |user_group| |data_permission| |id |-----|group_id | |name | |column | |value | and use this raw query to filter the results. SELECT * FROM article a INNER JOIN data_permission p0 ON p0.group_id = %s AND p0.column = 'source' AND p0.value = a.source INNER JOIN data_permission p1 ON p1.group_id = %s AND p1.column = 'category' AND p1.value = a.category; It's a simple problem, but I'm having trouble understanding if … -

Translating URL patterns in Django
I am trying to internationalize a dictionary Django web application and I am having problems with translating URLs. Here is my project's urls.py: from django.conf.urls.i18n import i18n_patterns from django.utils.translation import gettext_lazy as _ urlpatterns = [] urlpatterns += i18n_patterns( path(_('dictionary/'), include('dictionary.urls')), ) Here is my app's urls.py: from django.utils.translation import gettext_lazy as _ app_name = "dictionary" urlpatterns = [ path("", views.index, name="index"), path(_("define"), views.define, name="define"), path(_("define/<slug:headword_slug>"), views.headword, name="headword"), ] I have translated and compiled all the necessary files in my locale folders for both the project and app. When I change the language prefix in the URL, templates, forms, and various error messages are all translated very successfully. However, even though the language of the content changes, my URL patterns are always displayed in English. What am I doing wrong? -

django - How can I add different AppConfigs for testing different apps?
In my project I have two apps: main_app and reusable_app. reusable_app is supposed to be independent and reusable in other projects. It has its own models and signals. And I connected a lot of these signals to receivers in main_app. Doing ./manage.py test runs tests for both main_app and reusable_app. But the tests for reusable_app break when the signals are called because data needed for main_app to process these signals is not there. I don't want to have to load/setup data for main_app in reusable_app's tests. So, the solution would be to disconnect the signal receivers. Also, reusable_app tests should not have to know about disabling any signal receivers. I can create different AppConfigs that selectively connect or not these signal receivers. But how do I change the AppConfig depending on which app I'm running the test for? -

Dynamic price range filter in Django
I have a product model with attributes name, price, description, category. I want to create a dynamic price range filter with check boxes in the view. for example if I query my product like below: get_products = Product.objects.filter(category='Men') Now if the above query has a list of products with min_price = 500 and max_price=5000 then I would like to have 4 set of price range filters like below: 1)500-1500 2)1501-2500 3)2501-3800 4) 3801-5000 But the above should be dynamic based on min and max price value. I have tried to use range(min,max,steps) but it is very difficult to generate a dynamic price range filter. Any help is highly appreciated. -

nginx/django/uwsgi: can't load admin static css files
I have searched extensively and found many similar/related questions, none of the answers/suggestions solve my problems. I'm trying to describe my problems as in details as possible. Please bear with me for my lengthy post. I'm following the steps in the document https://docs.djangoproject.com/en/3.1/intro/ to create the polls app under mysite project and the app works as expected when I run "python manage.py runserver 0:8000" (accessed as http://hostname:8000/) to serve the pages.

Cannot get is_valid() to go back to template with bound form
In the Django docs, it says "We call the form’s is_valid() method; if it’s not True, we go back to the template with the form. This time the form is no longer empty (unbound) so the HTML form will be populated with the data previously submitted, where it can be edited and corrected as required." I am trying to get this behaviour to work. In views.py: def test(request): if request.method == 'POST': form = TestForm(request.POST) if form.is_valid(): return redirect('auctions/test.html') else: form = TestForm() return render(request, 'auctions/test.html', {'form': form}) In forms.py: class TestForm(forms.Form): testnumber = forms.DecimalField(max_digits=1) In test.html: <form action="{% url 'auctions:test' %}" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> Now, when I submit the form with a number that is more than 1 digit, is_valid() evaluates to False. When that happens, the docs says the template should be rendered with the bound form and the error. Instead, nothing happens, and I get ValueError: The view auctions.views.test didn't return an HttpResponse object. It returned None instead. -

The include tag in Django isn't working properly

Django returning old value for update User
I've created a simple on a settings page. It contains a few basic data such as First Name, Last Name (default Django User model) and then it links to a One to One model called Profile, which have more fields such as Address, City and State. I update it as follows in my views: def post(self, request): try: data = request.POST user_data = User.objects.get(id=request.user.id) first_name = data['first_name'] last_name = data['last_name'] phone = data['phone'] address = data['address'] address_two = data['address_two'] city = data['city'] state = data['state'] zip = data['zip'] country = data['country'] user_data.first_name = first_name user_data.last_name = last_name user_data.profile.phone = phone user_data.profile.address = address user_data.profile.address_two = address_two user_data.profile.state = state user_data.profile.city = city user_data.profile.zip = zip user_data.save() return render(request, 'pages/settings_profile.html', context={'success': "Settings updated"}) except Exception as e: print(e) print('error') return render(request, 'pages/settings_profile.html', context={'error':"Oops, an error occured saving your settings.

Prevent multiple submits in django form - setAttribute disable to false is not triggered
I'm trying to prevent users from clicking the submit button more than once on a django form. My form looks like this: <form method="post" autocomplete="off" enctype="multipart/form-data" id="expense-form"> {% csrf_token %} {{form}} <button id="expense-submit-button" class="uk-button uk-button-secondary uk-button-small" type="submit"> <span id="spinner-payment-button" class="spinner-border spinner-border-sm spinner-js"></span> Submit </button> </form Then in a script tag on the same template I got this document.getElementById("expense-form").addEventListener('submit', functSubmit); function functSubmit(event) { var button = document.getElementById("expense-submit-button") var spinner = document.getElementById("spinner-payment-button") button.setAttribute("disabled", true) spinner.classList.remove("spinner-js"); } When I hit the submit button, the form saves as usual, but the "disabled" attribute is never applied and the user can still click "submit" multiple times which results in multiple records in my db. Why isn't the event listener triggered? The reason I need this is because I got a form that takes some time to process (a few seconds) and I just need to signal to the user that its actually working as expected. -
How do i change the logged out redirect page?

Whenever i log out from the website i get redirected to the default django logged out page : I have created a logged_out.html file and its located in the same folder as botht the registration one and login . I think my mistake might be either in the *base.html file here: <li class = "nav-item"> <a class="nav-link" href="{% url 'users:logout' %}">Log Out</a> </li> or in the settings file if i have to include something that tells what to use .

I have a django app that is supposed to be used by different products, so it is a reusable app. This reusable app has DRE views, but for some views, I dont want to have always the same view permissions but instead I would like the final application (the product) to implement the view permission, because they can vary. For example: from rest_framework import permissions class MyCustomPermission(permissions.BasePermission): def has_permission(self, request, view): return finalAplicationPermission(request) if finalAplicationPermission else True and then use this custom permission in my view from rest_framework import generics from reusable_app import permissions class MyView(generics.GenericAPIView): permission_classes = (permissions.MyCustomPermission,) filterset_fields = ("somefield",) Any suggestion? Thanks in advance. -
Django-React Spotify Authentication with New User
I'm setting up a Django-React app and trying to allow users to login via Spotify which then takes them to a signup page to add username, bio, etc. or takes them to their profile page if they have already signed up. What's the best way to do this? I have been trying to use Django-allauth but having difficulty using this with React and not Django templates. Thanks.
