"No active account found with the given credentials" in django-rest-framework-simple-jwt
I can't optain jwt with django-rest-framework-jwt. After I post-requested with jwt-optaining-url, it said "No active account found with the given credentials" even though the given information(email, password) is correct. I think I've created a user with serializer in a wrong way. but can't come up with any new way. login view @csrf_exempt def facebook_login(request): body = dict(request.GET) code = body['code'][0] params_access = { "client_id": FACEBOOK_APP_ID, "redirect_uri": FACEBOOK_REDIRECT_URI, "client_secret": FACEBOOK_SECRET, "code": code } tokens = requests.get("https://graph.facebook.com/v5.0/oauth/access_token", params=params_access).json() access_token = tokens['access_token'] params_debug = { "input_token": access_token, "access_token": f'{FACEBOOK_APP_ID}|{FACEBOOK_SECRET}' } debug = requests.get("https://graph.facebook.com/debug_token", params=params_debug).json() params_user = { "fields": ["email"], "access_token": access_token } user_fb_data = requests.get("https://graph.facebook.com/me", params=params_user).json() user_email = user_fb_data['email'] user = User.objects.filter(email=user_email) if not user: user_data = { 'email': user_email, 'username': user_email, } user = UserSerializer(data=user_data, partial=True) if user.is_valid(): user.save() print("saved!!!!!!!!!!!!!!!") else: print("error", user.errors) jwt_data = { 'email': user_email, 'password': access_token } jwt = requests.post(JWT_OPTAIN_URL, data=jwt_data).json() access_token = jwt['access'] refresh_token = jwt['refresh'] data = { 'access_token': access_token, 'refresh_token': refresh_token } return Response(data, status=status.HTTP_201_CREATED) Serializer class UserSerializer(serializers.ModelSerializer): def create(self, validated_data): user = super().create(validated_data) user.set_password(self) user.save() return user class Meta: model = User fields = ('email', 'username', 'refreshToken', 'password') extra_kwargs = {'password': {'write_only': True}} I expect the jwt is created with email and password information. -

(Django) How can I embed the login form inside the landing page (main page) of the website?
I want to have the user login directly on the landing page that the website starts on. This page has username and password input boxes as well as a "login" button, but I can't seem to connect it such that it performs the task of logging in. Right now it just redirects to the same page with the message "This page isn't working. HTTP Error 405." I have already managed to make a separate page for logging in (it works), but I want to remove it and just have the user login from the main page. The part of my landing page index.html that will contain the form: <form class="login-container" method="POST"> <div class="input"> <input class="username_field" type="username" placeholder="E-Mail or Username" value="{{ form.username }}"> </div> <div class="input"> <input class="password_field" type="password" placeholder="Password" value="{{ form.password }}"> </div> {% for field, error in form.errors.items %} {% if field != '__all__' %}{{ field }}{% endif %} <span style="color:red">{{ error | striptags }}</span> {% endfor %} <button type="submit"></button> </form> My existing login.html that works: {% load static %} <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="{% static 'login.css' %}"> </head> <body> <h1 style="text-align:center;">Log In to Planda</h1> <div class="container"> <img src="{% static 'planner/images/planda.png' %}" class="center"> … -
Django Saleor: How build contact form?
I develop an ecommerce site with the Django Saleor framework: https://getsaleor.com/ It's really well designed, thanks to the developers and the community! But I have a small problem: I would like to create a contact form but I have not seen anything about it either in the documentation or elsewhere... Does anyone know what is the best way to do it? When I add HTML directly after creating a page from the dashboard, it is not interpreted. I have the basics with Django development but I don't know how to integrate my form into the page created from the dashboard. Thank you in advance and at your disposal for any further information.

Why is Django looking for templates in the wrong directory
Why is Django looking for Template in the wrong directory? django is looking here: sempire\double_ch_control_app\templates\double_channel_control.html instead of conventionally here: sempire\double_ch_control_app\templates\double_ch_control_app\double_channel_control.html I have more than one app on the django project but this very app keep looking up templates on the wrong directory -
how can I implement this idea?
I have a Post model and a Tag model each related with a many to many field, the tag is describing the post somehow, like #frontend_development or #coding ,meaning a way to classify the posts and to reach the posts related to certain topics. the thing is when creating the post , the creator does not type the tags in tag section like here on Stackoverflow , instead , they choose from a pre existing list of tags fetched from the database and they can choose more than one tag . but I wanted more functionality .. to classify those tags to make it easier for the creators to choose from .. say hundreds of tags , by grouping every similar tag from the same type together by a subject, like both #coding and #frontend_dev both belong to the Tech subject/ #entrepreneurship and #Human_Resources both belong to the Business subject , so I have made a third model called SubjectTag related to the Tag model with a many to many field also. is that a good implementation ? the problem is , I want the post creator to be able to choose from the list of subject tags and automatically … -
django not giving me the file even though it the link is directed to the file
I am trying to download a file when a link is clicked. The link is generated dynamically using javascript when the file has been created. In my template the function that adds the links looks like: function Download(desiredLink) { var a = $('<a />'); a.attr('download',desiredLink); desiredLink = {{MEDIA_URL}} +desiredLink+'.docx'; a.attr('href',desiredLink); a.text("Download"); $('body').append(a); }; I have specified the MEDIA_URL in my settings.py file like: MEDIA_ROOT = os.path.join(BASE_DIR, 'documents/') MEDIA_URL = '/documents/' The link generated has the correct url when I inspect it. But when I click the button it tries to download the file but says Failed-No file. Any solution would be appreciated. Thanks in advance -

Form do not work after submitting once python Django
Posting views, urls and html to be clear. I am printing search results in a html tables on submit. Form and result display on the same page. My form works as expected only once, if I try to use the form second time after printing the search result for the first search criteria it throws me error saying: AttributeError 'NoneType' object has no attribute 'replace'. And the url is pointing to the definition which is returning me the response(stream_response) like : localhost/stream_response .To put the form to work I need to manually refresh the page then the form works as expected (back to localhost/checkProject.html). Also, there are three dropdown items which I am printing from database upon initial page load. After, one search the drop down values are disappeared too. You can see the dropdowns on the below html. views.py def stream_response(request): data_list = []; flag = 0; if request.method == 'POST': request.GET.get('Check') flag = 0; field = request.POST.get('inputValue') projectName = request.POST['projectName'].strip() communityPartner = request.POST.get('communityPartner').replace('-','') campusPartner = request.POST['campusPartner'].replace('-','') academicYear = request.POST['academicYear'].replace('---','') print(sqlfiles.checkProjectsql(projectName,communityPartner,campusPartner,academicYear)) cursor = connection.cursor() cursor.execute(sqlfiles.checkProjectsql(projectName,communityPartner,campusPartner,academicYear),params=None) rows = cursor.fetchall() if(rows != []): print("why am i here") for obj in rows: if (projectName.strip().lower() in obj[0].split("(")[0].strip().lower()): flag =2 if(projectName.strip().lower() == obj[0].split("(")[0].strip().lower()): flag=1 … -

Override detail url to appear as list
Since I am using request.user to determine the user from the JWT that was used to authenticate the request, I think it is a little misleading to keep the normal approach of /users/pk/ since changing the pk url parameter will have no impact on the user being interacted with. For example, I'd like to make a PATCH request to /users/ & retrieve the user's id from request.user rather than making the request to /users/1/, getting the user id from the url param. users/viewsets.py class UserViewSet(viewsets.ViewSet): def list(self, request): queryset = get_user_model().objects.get(id=request.user.id) serializer = UserSerializer(queryset) return Response(serializer.data) def create(self, request): post_data = request.data serializer = UserSerializer(data=post_data) if serializer.is_valid(): serializer.save(owner=self.request.user) return Response(serializer.data, status=201) print(request.data) return Response({"error": "Data is invalid."}, status=400) def update(self, request, pk=None): post_data = request.data obj_instance = get_user_model().objects.get(id=request.user.id) serializer = UserSerializer(instance=obj_instance, data=post_data, partial=True) if serializer.is_valid(): serializer.save(owner=request.user) return Response(serializer.data, status=204) print(request.data) return Response({"error": "Data is invalid."}, status=400) def partial_update(self, request): post_data = request.data obj_instance = get_user_model().objects.get(id=request.user.id) serializer = UserSerializer(instance=obj_instance, data=post_data, partial=True) if serializer.is_valid(): serializer.save(owner=request.user) return Response(serializer.data, status=204) print(request.data) return Response({"error": "Data is invalid."}, status=400) def retrieve(self, request): queryset = get_user_model().objects.filter(id=request.user.id) user = get_object_or_404(queryset, pk=request.user.id) serializer = UserSerializer(user) return Response(serializer.data) def get_permissions(self): if self.request.method == "POST": self.permission_classes = (AllowAny,) return super(UserViewSet, self).get_permissions() … -

How can I download a word document created by a django app on the same app
I have a django app the creates a word document from a template. After user input I make an ajax request to my views.py and create the document. After the document is created I want it to be downloaded from the server. The document is saved in the static/documents folder. In my template I have the following: $.ajax({ url: '/ajax/result/', data : { 'values': JSON.stringify(dataJson), 'general': JSON.stringify(generalData) }, method: 'GET', contentType: "application/json", dataType: 'json', success: function (data){ Download('documents/'+document.getElementById('id_file_name').value+'.docx'); alert(data); }, error: function(data) { alert("something went wrong"); } }); function Download(url) { document.getElementById('my_iframe').src = url; }; The Download function is the function that downloads the document. I can get the file name of the document since it is from user input. I am currently getting a 404 error on my console. Thanks in advance -
