redirect @login-required for specific pages
In Django, I have in my files: settings.py LOGIN_URL = 'login' LOGOUT_REDIRECT_URL = 'frontpage' LOGIN_REDIRECT_URL = 'myaccount' views.py @login_required() def checkout(request): cart = Cart(request) if not len(cart): return redirect('cart_view') ...more code... my question is simple... How do I set the @login_required, so that instead of the myaccount page being the redirect URL, I can send it back to checkout page? In other words, where can I override LOGIN_REDIRECT_URL when needed? Thank you, -

Django parler: error when for same translation
I've just added django-parlel to my project and I'm wondering is it my bad or it's really impossible to have same translation more then once. Case I'm trying to add translation for Polish language for word "Sport", in polish it would be "Sport", just same as in English (which I have by default in app). When trying to add this getting error both when adding from admin panel and when loading fixture. I know that i might leave it blank and it won't really be that bad however I need to have translation for each single word. I'm assuming there is a constraint in parlel ;( Thanks in advance. Error in Admin -
Does a Django site need a Postgres database when hosting on Heroku? Can I remove the Postgres add-on?
I have a website that I built using Django and deployed on Heroku. The tutorial I followed had me set up a Heroku Postgres database attached as an add-on. After Heroku's recent pricing changes the Postgres database has gone from free to $5 / month. Maybe static isn't the correct word, but the site doesn't have user accounts, collect user information, or otherwise have any need for a database. I believe the only information that's stored in the database is login info for the Django admin site. I was able to export a .pgdmp file from Heroku of the data stored in the database but couldn't make heads or tails of the contents. Here's the settings.py file code for the database section: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', } } import dj_database_url db_from_env = dj_database_url.config(conn_max_age=500) DATABASES['default'].update(db_from_env) My question is can I delete this add-on from the Heroku CLI or dashboard without breaking the site in production? Would I need to change anything in my settings.py file or elsewhere in my Django code first? I assume I would still be able to access the Django admin page on the development server, is that assumption correct? Sorry … -

Coupon code not working for items in cart

Styling prefilled Django radio input as buttons
I have a Django form field that is prefilled({form.clothingType}) and using widget gave it the attribute of class="closet-form-section form-clothing-type". The form is rendered out in html as <div id="id_clothingType" class="closet-form-section form-clothing-type"> <div> <label for="id_clothingType_0"><input type="radio" name="clothingType" value="11" class="closet-form-section form-clothing-type" required="" id="id_clothingType_0"> Accessory</label> </div> <div> <label for="id_clothingType_1"><input type="radio" name="clothingType" value="12" class="closet-form-section form-clothing-type" required="" id="id_clothingType_1"> Top</label> </div> <div> <label for="id_clothingType_2"><input type="radio" name="clothingType" value="13" class="closet-form-section form-clothing-type" required="" id="id_clothingType_2"> Outerwear</label> </div> <div> <label for="id_clothingType_3"><input type="radio" name="clothingType" value="14" class="closet-form-section form-clothing-type" required="" id="id_clothingType_3"> Bottom</label> </div> <div> <label for="id_clothingType_4"><input type="radio" name="clothingType" value="15" class="closet-form-section form-clothing-type" required="" id="id_clothingType_4" checked> Shoe</label> </div> </div> My question is how do I style the radio inputs as buttons such that it changes its background color when it is checked without changing the html (form template)? Is there an alternative solution via widget, views.py of even models.py? Thank you! The problem is that the input is within the labels, so I am unable use the conventional way of the input:checked + label to style the radio inputs. In this case the 5th radio button(Shoe) should have a different background color as the others. -

Django rest framework - restricting user from granting himself permission
I have a django-program that has a few number of different permission levels. For example, I have a super-user, a doctor, an assistant and a patient. I have a class AssistantViewSet(ModelViewSet) which allows to change an assistant user. I just found out that an assistant might go directly to the link that corresponds to that ModelViewSet with method PUT (which is a resonable behavior as an assistant can change their own information), and change their permissions by sending a permission_list key with many permissions they shouldn't have. how can I make sure that an assistant will be able to change their information without having the ability to change their permissions? my code: class AssistantViewSet(ModelViewSet): serializer_class = AssistantSerializer queryset = Assistant.objects.all() permission_classes = [AssistantViewPerm, ] def get_queryset(self): assistants = Assistant.objects.filter(...) return assistants and the permission class: class AssistantViewPerm(BasePermission): def has_permission(self, request, view): action = view_action_map(request) try: if action == 'update': ... except: ... return checkBasicPerms(...) and checkViewPerm(...) -

I am currently running my project locally, and each time I do an API call with the browser, I see the server log something similar: my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/css/default.css HTTP/1.1" 404 179 my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/js/bootstrap.min.js HTTP/1.1" 404 179 my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/js/jquery-3.5.1.min.js HTTP/1.1" 404 179 my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/js/csrf.js HTTP/1.1" 404 179 my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/js/ajax-form.js HTTP/1.1" 404 179 my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/js/default.js HTTP/1.1" 404 179 my_table | [08/Jan/2023 20:20:42] "GET /static/rest_framework/js/prettify-min.js HTTP/1.1" 404 179 There are a tons of static files that are served via the API. If I do the same with Postman or similar, here is the log: my_table | [08/Jan/2023 20:25:12] "GET /api/v1/category/ HTTP/1.1" 200 2 It looks like it only sends the response I wanted, via JSON or whatever. I was wandering if there is a way to prevent Django from serving static files at all, since I will only use the Rest Framework, or maybe gRPC in the future, but never static files. I tried to delete the static file constant from settings, and then nothing … -
Use node module in django
I'm trying to use nodejs modules (lodash) inside of my Django app but nothing happen. The architecture is as follow: - myproject - dist - myapp - templates - index.html - apps.py - views.py - ... - myproject - settings.py - urls.py - ... - nodes_module - static - js - script.js - manage.py - package.json I edited my settings.py so nodes_module/ is considered as static: STATIC_URL = "/static/" STATIC_ROOT = 'dist/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ('node_modules', os.path.join(BASE_DIR, 'node_modules/')), ) And here is the content of my index.html: hello <div id="result"></div> <script>console.log("yolo")</script> <!-- This should write "2 4 6 8 10" on console and page but doesn't --> {% load static %} <script src="{% static 'node_modules/lodash/lodash.js' %}"> import _ from 'lodash'; console.log("yolo2") const array = [1, 2, 3, 4, 5]; const doubled = _.map(array, function(n) {return n * 2;}); const resultElement = document.getElementById('result'); resultElement.innerHTML = doubled; console.log(doubled); </script> I got a lot of errors while trying but now, with this architecture and code, I don't have errors anymore but nothing appear on my page except the "hello". For some reasons, the first console.log("yolo") does appear on the console but not the second one console.log("yolo2"). It's like it never went … -
How can I add related models on the form at the same time?
I need your help with something. I'm new to the software field. I would like to consult you on an issue that I am stuck with. I don't know much about Django docs. My English is not very good. My problem is that I have two models, Boat model and Features model, I assigned a foreignkey to the features model and associated it with the boat model. I created two forms for these models. Features Model Boat Model BoatForm FeaturesForm I need to save the form at the same time in the views, but I can't assign the foreign key. In summary, while adding a new boat, I need to save its features at the same time. Sorry if the English pronunciations are wrong.
