How to access Authorization code flow, Implicit Flow and Hybrid flow in Django oauth toolkit
I want to implement OpenID connect in my project. So I started using Django Oauth Toolkit. I was able to make the changes in Dajango Rest framework menu and was able to test the Resource owner password-based flow using the curl command curl -X POST -d "grant_type=password&username=<user_name>&password=<password>" -u"<client_id>:<client_secret>" http://localhost:8000/o/token/ After that I made all the changes as mentioned in the OpenId Connect menu. I have Generated RSA private key Added the changes as mentioned in the documentation Then I registered applications for each flow as mentioned in the documentation. Then the problem arise.

Django - How to store existing Data in Variable from Database and Update it with another variable
I am facing an issue for few days but could not get the findings to solve it. Suppose, I want to update a record into database using a form and want to keep the existing data into a variable and update it using form and keep the updated data into another variable. Please be inform that i made a solution using session but want another way to solve it. def client_edit(request, client_id): client = Client.objects.get(id=client_id) previous_client_name = client if request.method == 'POST': form = AddClientForm(request.POST, instance=client) if form.is_valid(): client2 = form.save(commit=False) client2.save() context = { 'user': request.user, 'client': client2, 'previous_client':previous_client_name, } return render(request, 'did_app/client_edit.html', context=context) else: return render(request, 'did_app/client_edit.html', {'form': form}) else: return render(request, 'did_app/client_edit.html', {'client': client}) I tried this way but both client and previous_client return the same data. Please suggest. Thanks in advance -

Application and request contexts in Flask
I really need your help. I am currently doing a project with Flask and I have used the application and request contexts but to this day I have not been able to understand why it is necessary to use them? I don't understand how they work. Every time a request is made to a web app developed with Flask a new instance of the Flask class is created or really how a Flask app works under the hood. It would be very helpful if you help me solve this doubt that is driving me crazy. Thank you very much in advance. I've read everywhere and I still don't understand. -

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}) -

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) … -
