(Django) Reverse dynamic urls with multiple arguments using Django Views
I am trying to pass two arguments to make a dynamic URL for each post of a blog app I'm working on. I get it to work if I pass the id, but don't know what's the syntax when using +1 arguments (nor if I'm doing things right). I want to make urls be 'post/<int:pk>/<slug:slug>/' but can only make it work with the id: 'post/<int:pk>/ Here's how I have it now: URLS.PY urlpatterns = [ ... path('post/<int:pk>/<slug:slug>/', PostDetailView.as_view(), name='post-detail'), path('post/new/', PostCreateView.as_view(), name='post-create'), path('post/<int:pk>/<slug:slug>/update/', PostUpdateView.as_view(), name='post-update'), path('post/<int:pk>/<slug:slug>/delete/', PostDeleteView.as_view(), name='post-delete'), ... ] VIEWS.PY class PostDetailView(DetailView): model = Post I am calling this in the template: <ul class="secondary-menu menu-list"> <li class="menu-item"><a href="{% url 'post-update' object.slug %}">Edit Post</a></li> <li class="red-button"><a href="{% url 'post-delete' object.slug %}">Delete</a></li> </ul> And have this function to retrieve the path to any specific instance in MODELS.py def get_absolute_url(self): return reverse('post-detail', kwargs={'pk': self.pk, 'slug':slug}) I get the following error during template rendering Reverse for 'post-detail' with arguments '(1,)' not found. 1 pattern(s) tried: ['post/(?P<pk>[0-9]+)/(?P<slug>[-a-zA-Z0-9_]+)/$'] -

Django regex url parsing to calling wrong view
I have a Django 2.2 project (using the rest framework) where I need to call a view function with a url of the following format: /class/students?date=07092019 and I've set up the following url route to handle this url:re_path(r'^class/students%3Fdate%3D(?P<date>\w+)/$',StudentsInClassView.as_view() ,name='student'). The corresponding view function has the following definition: class StudentsInClassView(APIView): def get(self, request, date,format=None): For some reason, whenever I go to url, it gets converted to /class/students/?date=07092019 and a different view, with the url path('nba/students/',StudentsView.as_view() ,name='students'), gets called instead. If I remove the "?date=" from the url and just include the actual date, the StudentsInClassView is called as expected. I've escaped both the question mark and the equal sign but doing so doesn't seem to make a difference. How can I get the "?date=" slug to remain in the url as it is used to call the StudentsInClassView? Is there a different regex that could be used to match the whole url? -

a superior user can change other user's password
as an assignment, i need to create this simple web app using django as the admin, I'll create a "low level" username + password. the salesmanager will then give this username and password to his salespersons. this is a "read-only" username. that means, the salespersons can only read/see the data available on this company webapp, simultaneously using just this one username. this username can't change the password. if one of the salespersons resigns, the password will need to be changed. because the salesperson turnover is rather high, I want the salesmanager to be able to change the password for this username, so i don't have to do it myself everytime. the salesmanager himself will use a different username + password as he has more permissions. how do i use django's change password to work in this situation? thank you -

Django Model Field - is there anyway to define a field that stores an object
I'm trying to add Django to my react project. Currently, I'm stuck on defining correlating model fields in Django to what I had in React state. This is what my old state looks like (when I stored all the info directly in the state) This is what my new state looks like (when I fetched the data from api and stored it into the state) The reason I want to have "teamBackground", "textColor", "votedUpColor", "votedDownColor" properties is that I want to be able to style each team. I tried defining these properties as CharField and JSONField, but they don't seem to be working. Is there anyway to solve this problem? -

How to render db data from consumer into template using django channels

Specify model names in select_for_update instead of relations
I would like to specify the table/model names instead of the relations in the QuerySet's model. Reason being the relation I'm linking to is a multi-table inheritance model. When I use select_for_update and provide relations using the of parameter, only the parent tables are "selected for update". Consider the piece of code: order = Order.objects.filter(uuid=order_uuid).prefetch_related( Prefetch( lookup='items', queryset=items ) ).select_related('outlet').select_related('user').select_related('outlet__group') \ .select_for_update(of=('self', 'outlet')) Here, outlet is a relation defined by outlet = models.ForeignKey(Outlet, on_delete=models.PROTECT, related_name="orders") Both the Order as well as Outlet models are sub-models to Transaction and Cashless models (which are situated in another Django app) By logging PSQL, this is the query that is being executed: SELECT "payment_gateway_transaction"."uuid", "payment_gateway_transaction"."ref_number", "payment_gateway_transaction"."shop_id", "payment_gateway_transaction"."user_id", "payment_gateway_transaction"."timestamp", "payment_gateway_transaction"."amount", "payment_gateway_transaction"."payment_method", "payment_gateway_transaction"."transaction_status", "payment_gateway_transaction"."service", "cashless_order"."transaction_ptr_id", "cashless_order"."token", "cashless_order"."outlet_id", "cashless_order"."order_status", "cashless_order"."order_start_time", "cashless_order"."order_end_time", "cashless_order"."order_collect_time", "cashless_order"."order_review", "cashless_order"."order_ratings", "authentication_user"."id", "authentication_user"."password", "authentication_user"."last_login", "authentication_user"."is_superuser", "authentication_user"."email", "authentication_user"."student_id", "authentication_user"."first_name", "authentication_user"."last_name", "authentication_user"."date_joined", "authentication_user"."ip_address", "authentication_user"."mac_address", "authentication_user"."location", "authentication_user"."phone_number", "authentication_user"."total_spent", "authentication_user"."is_banned", "authentication_user"."needs_student_id", "authentication_user"."generated_at", "authentication_user"."verify_token", "authentication_user"."is_active", "payment_gateway_shop"."uuid", "payment_gateway_shop"."name", "payment_gateway_shop"."location_id", "payment_gateway_shop"."location_coords", "payment_gateway_shop"."tax_applicable", "payment_gateway_shop"."percentage_tax", "payment_gateway_shop"."gst_number", "payment_gateway_shop"."open", "payment_gateway_shop"."active", "payment_gateway_shop"."group_id", "cashless_outlet"."shop_ptr_id", "cashless_outlet"."start_time", "cashless_outlet"."end_time", "cashless_outlet"."break_start_time", "cashless_outlet"."break_end_time", "cashless_outlet"."items_limit", "cashless_outlet"."image", "cashless_outlet"."description", "cashless_outlet"."on_cashless", "cashless_outlet"."ratings", "cashless_outlet"."latest_token", "auth_group"."id", "auth_group"."name" FROM "cashless_order" INNER JOIN "payment_gateway_transaction" ON ("cashless_order"."transaction_ptr_id" = "payment_gateway_transaction"."uuid") INNER JOIN "authentication_user" ON ("payment_gateway_transaction"."user_id" = "authentication_user"."id") INNER JOIN "cashless_outlet" ON ("cashless_order"."outlet_id" = "cashless_outlet"."shop_ptr_id") INNER JOIN "payment_gateway_shop" ON ("cashless_outlet"."shop_ptr_id" = "payment_gateway_shop"."uuid") INNER … -
Add values to context for render in Django
I have the following code inside a view: return render( request, 'home/index.html', { 'mobile':False, 'title':'Home', #'year': datetime.now().year, } ) So I used to always calculate the year in every view. I had to since it was needed in my layout.html Because of that I thought it would be a good idea to extract this calculation so I don't have to write it in each view specifically. I tried this using the following middleware: from datetime import datetime from django.utils.translation import gettext as _ def get_vars(get_response): def middleware(request): request.year = datetime.now().year return get_response(request) return middleware But it seems that the year variable is not added the same way it would be in the view. So my question is: How can I implement this functionality?` If not with a middleware how can I otherwise do it?
