Django OAuth Authentication
I built an app (Django backend, React frontend) that whenever a client login it will generate JWT authentication. React will store the access token and client can use it to access Django backend database. Then I want to add in social login feature (Google) so I will get back access token from that as well. However, this access token is different from the JWT access token generated before, so I wonder how can I integrate both ways of logging in a user smoothly on both Django and React? For JWT I use djangorestframework-simplejwt For social login I use django-allauth I can run each individual way perfectly on React, but I don't know how to keep both the installations of JWT and allauth in Django settings. -
Django Template changing html attribute based on slug and current request
When I tried to iterate through a list of post titles to create links in a django template the urls never match the requested path (matching the current web page should alter the formatting on the page for that list item). When I try and change things, Django spits out a 404 error which doesn't let me diagnose the problem or it "works" but not as expected. the relevant url patterns: path('<slug:post>', views.blog_post, name='entries') the relevant views function: def blog_post(request, post): try: return render(request, 'blog/post.html', { 'post_title':post, 'post_content':blog_posts[], 'posts':blog_posts.keys }) except: raise Http404() the template: <ul> {% for post in posts %} {% url "blog:entries" "{{post}}" as blog_entry %} <li><a href="/blog/{{post}}" {% if request.path == blog_entry %} class="active"{% endif %}> <span class="item">{{post}}</span> </a></li> {% endfor %} </ul> I suspect the {% url "blog:entries" "{{post}}" as blog_entry %} in the template is not resolving correctly as when I replace the href with {% blog_entry %} it causes a 404 error. I have tried hard coding it in, I have tried different ways of writing the url, I have tried changing the syntax (in case I am doing it incorrectly. I have checked the page source when I have run tests. I … -

How to save Request URL from inspector in Django Model
I'm trying to implement a web application in which the user fills out a form and separately there is a form that the user fills out and selects a route on the map. I use Mapbox for this. In HTML it looks like I have a separate form in the form element and a separate map in the div element. When I built a route in the inspector, I find a processed request with the GET method and the Request URL. My question is how to save this URL request together with the form, or at least separately? How do I even save this URL request to the Django Model. Part from my model.py:: class Route(models.Model): route_name = models.CharField(max_length=50) lvl = models.IntegerField(default=0) about = models.TextField(max_length=1500) total_distance = models.IntegerField(default=0) country = models.ForeignKey(Country, on_delete=models.CASCADE) def __str__(self): return self.route_name def __str__(self): return self.about class RoutesURL(models.Model): url = models.CharField(max_length=1000) def __str__(self): return self.url And my views.py: def getForm(request): form = RouteForm() if request.method == 'POST': form = RouteForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect('home') return render(request, 'routes_form/route_form.html', {'form': form}) -
Select related is not returning all the values from the relation in Django
I'm doing this query SELECT [User].[User_Id], [User].[Client_id], [User].[EMail], [User].[First_Name], [User].[Family_Name], [User].[Telephone], [Clients].[Client_Id], [Clients].[Name], [Clients].[Organization_type] FROM [User] INNER JOIN [Clients] ON ([User].[Client_id] = [Clients].[Client_Id]) WHERE [User].[EMail] = 'birna@athygli.is' In the SQL server is working fine even when I print in django the queryset looks good, but, when getting the results is not getting it from the Clients` table, It has to be something with the relation between tables in Django but I really don't know where Here are my two models class V2_Clients(models.Model): Client_Id = models.CharField(primary_key=True, max_length=50) Name = models.CharField(max_length=255, null=True) Organization_type = models.CharField(max_length=128, null=True) class Meta: managed = True db_table = "[Clients]" class V2_Users(models.Model): User_Id = models.CharField(primary_key=True, max_length=50) Client = models.ForeignKey(V2_Clients, on_delete=models.CASCADE) EMail = models.CharField(max_length=250) First_Name = models.CharField(max_length=50, null=True) Family_Name = models.CharField(max_length=50, null=True) Telephone = models.CharField(max_length=50, null=True) class Meta: managed = True db_table = "[User]" This is where I do the query, even when I do print(v2_user.query) I get the same SQL shown at the top, but is not getting the values from the Clients table only the results from the User v2_user = V2_Users.objects.using('sl_v2').filter(EMail=jsonData['Client']['Client_Email']).select_related() What could be the issue? -
How do I use multi tag filters in Django REST Framework API response?
first of all I apologize if I did not ask a question using better words. I am building a DRF App, I have Products Model, ProductSerializer and ProductsSummaryView. Furthermore, I have Workspace Model (not going to talk about it as it is not related to the issue). Now, I want to return those products details in success response which are attached with a specific Workspace, filtered on some parameters. What I have done: I defined filterset_fields and filter_backends. It works fine. For example, if I go to this URL {{domain}}/path/?country__title=Japan, it filters the data for Japan and show me. But the problem is, I want to filter using multi-tag, such as let's say if I want to see details for Japan and Korea, so I want something like this {{domain}}/path/?country__title=Japan&country__title=Korea, but it is not working and it just returns all the details. I even tried adding empty list format in the URL and tried this URL {{domain}}/path/?country__title[]=Japan&country__title[]=Korea, but it still did not work. Can anybody help me in this? My Product Model is: class Product(BaseModel): """Product model to store all prices of a product and related brand and countries it's available in""" product = models.CharField(max_length=255) country = models.ForeignKey(Country, null=True, on_delete=models.DO_NOTHING) … -

How to save Mapbox routes in Django Model
I have an html page with a form and Mapbox. Below is a picture of what it looks like. I want the user to fill out a form and then plot a route on the map (see screenshot). Both the data of this form and the route itself were saved to the database. When filling out the form on the left, everything is successfully saved to the database. But I have a question, how to save the routes that I build on the Mapbox map. I checked through the Network in the browser inspector, and the API itself creates the Mapbox request. But here's how to save it to my table... For example I have a table Route and the columns are id, latitude and longitude. Perhaps tell me in which direction to think, tk. I broke my head that how to pull this data.
