DRF - lack of JWT when creating user instance
I'm struggling with jwt. When I create user's instance, there is not jwt. When I try to obtain jwt with registered credentials I receive info that provided credentials are not correct. It works fine when I create superuser via cmd. serializers: from rest_framework import serializers from django.contrib.auth.models import User from rest_framework import serializers class UserSerializer(serializers.ModelSerializer): class Meta: model = User write_only_fields = "password" read_only_fields = ('id',) fields = ["email", "password", "first_name", "last_name"] for field in fields: extra_kwargs = {field: {'required': True,'allow_blank': False}} def create(self, validated_data): validated_data["username"] = f'{validated_data["first_name"]}_{validated_data["last_name"]}_{User.objects.count()}' return User.objects.create(**validated_data) signals: from django.db.models.signals import post_save from django.dispatch import receiver from django.contrib.auth.models import User from rest_framework.authtoken.models import Token @receiver(post_save, sender=User) def create_auth_token(sender, instance=None, created=False, **kwargs): if created: Token.objects.create(user=instance) views class CreateUserView(CreateAPIView, GenericViewSet): model = User permission_classes = [ permissions.AllowAny ] serializer_class = UserSerializer response = {} def create(self, request): validation_selializer = UserRegistrationSerializer(data=request.data) if validation_selializer.is_valid(): final_selializer = self.get_serializer(data=validation_selializer.data) if final_selializer.is_valid(): self.response = { "info":{ "status":"created", "email":validation_selializer.data["email"] } } return Response(self.response, status=status.HTTP_200_OK) self.response = validation_selializer.errors return Response(self.response, status=status.HTTP_400_BAD_REQUEST) -
Django Form Dropdown List Won't Display
I want to create a dropdown list in a form. I followed this approach here. If I use {{ form.as_p }}, the dropdown list renders just fine. But rendering the form using as_p looks terrible. Instead, I loop through the form fields and access their parameters so I can stylize the inputs. I try to catch the field of the dropdown list using an if-statement with condition field.widget.input_type == "select". When the page renders, I should see "This is where my dropdown goes" where my dropdown list field is supposed to be. But that doesn't happen, the field gets rendered as a text input like every other field, so my if-statement is not working. I debugged my view function and confirmed that the field corresponding to the dropdown list does have parameter .widget.input_type == "select". What am I doing wrong? <form action="{% url 'myapp:newrecord' %}" method='post'> {% csrf_token %} {% for field in form %} <div class="form-group row"> {% if field.widget.input_type == "select" %} <p>This is where my dropdown goes.</p> {% else %} <label for="{{ field.id_for_label }}" class="col-sm-2 col-form-label">{{ field.label }}</label> <div class="col-sm-10"> <input type="text" name="{{ field.html_name }}" class="form-control" id="{{ field.id_for_label }}" placeholder="{{ field.label }}" required> </div> {% endif %} … -
Can we combine multiple exists() queryset API calls into a single DB call using annotate?
I have a decorator.py function to check if a logged user has permission to access a view. def allow_only_admins_authors_coauthors_reviewers_specialists(view_func): def wrapper_func(request, *args, **kwargs): email_of_logged_user = request.user.email book_id = kwargs['pk'] # Get the book id if (request.user.is_admin or \ (Coauthors.objects.filter(paper=book_id, email=request.user).exists()) or \ (Book.objects.filter(Q(id=book_id, author=request.user) | Q(id=book_id, author__email__in=request.user.get_secondary_emails_flat_list)).exists()) or \ (Token.objects.filter( Q(book=book_id, email=email_of_logged_user) | Q(book=book_id, email_which_was_actually_used_to_retrive_token__emails__icontains = email_of_logged_user) # 'email_which_was_actually_used_to_retrive_token' contains the actual email which was used by the reviewer to retrieve the token. Its different than the email to which the token was originally sent. ).exists() # Sometimes, the token might be deleted. In such case, system shall check if the logged user is the reviewer within the Review model. ) or \ (Review.objects.filter(paper=book_id, user__email = email_of_logged_user).exists()) or \ (SpecialistAssignment.objects.filter(raw_book=book_id, user=request.user).exists())): return view_func(request, *args, **kwargs) else: return HttpResponse('You are not authorised to view this page!') return wrapper_func This function would make multiple DB calls due to multiple the exists() API checks. Is there any way we can combine these multiple exists() into a single DB query using annotate? Secondly, is this approach faster than using django-rules? -
Django can't find my DetailView with Primary Key
I'm trying to make a simple page with Django where posts are being displayed using primary keys. However, the DetailView page with my posts can't be displayed. This is my model: class Post(models.Model): author = models.CharField(max_length=100) title = models.CharField(max_length=100) posted_date = timezone.now() text = models.TextField() def get_absolute_url(self): return reverse("postdetail", kwargs={"pk": self.pk}) def __str__(self): return self.title and here is my url pattern list: urlpatterns = [ url(r'^posts/(?P<pk>\d+)$', views.PostDetail.as_view(), name="postdetail"), url(r'^$', views.index, name="index"), url(r'^thanks/$', views.Thanks.as_view(), name="thanks"), url(r'^postlist/$', views.PostList.as_view(), name="postlist"), ] Here is the DetailView: class PostDetail(DetailView): context_object_name = 'post_details' model = Post I can't see where I might have a mistake. I have a ListView that shows my posts including the primary keys. But when I try to open the URL http://127.0.0.1:8000/posts/1/ I get: `Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/posts/1/ Using the URLconf defined in myproj.urls, Django tried these URL patterns, in this order: admin/ ^posts/(?P<pk>\d+)$ [name='postdetail'] ^$ [name='index'] ^thanks/$ [name='thanks'] ^postlist/$ [name='postlist'] The current path, posts/1/, didn’t match any of these.

how can I auto scroll down - chat app with django

Displaying names of the DB tables that contain specific data
I was able to get the names of the tables of DB with specific data in Python like this: r = list(conn.cursor().execute('''select m.name from sqlite_master m where m.type = 'table' and exists (select 1 from pragma_table_info(m.name) m1 where m1.name = 'customer_id')''')) print('Names of the tables that contain customer data:\n','\n'.join(map(str, r))) The output is: "actor" and "film actor" Is there any way to get the same output in Django website? I just can't think of any way to do that. DB that I'm using is Sakila. I've generated model objects for every table already. -

Env vars and Docker differences between dev, staging, and prod
Although my specific example involves Django, Docker, and Heroku, I believe these are pretty general testing/QA questions. I have a dockerized Django app tested in dev with Selenium confirming that my static files are being served correctly from my local folder (EXPECTED_ROOT = '/staticfiles/'). This app is deployed to Heroku and I can see (visually and in the dev tools) that the static files are being pulled in from CloudFront correctly as well. I want to formalize this with the same test I'm using in dev. My first question is related to if/how environment variables are used for tests: Do I add for example EXPECTED_ROOT = 'https://<somehash>.cloudfront.net/' as an env var to Heroku and use it in the Selenium test? Also, to run this test in staging I would need to install Firefox in my Docker image like I do in dev. Perhaps this is ok in staging, but in prod I believe I should be aiming for the the smallest image possible. So the question is about differences between staging and prod: Do I keep Firefox in my staging image, run the tests, and then send to production a replica of that Dockerfile, but now without firefox? Any help … -

Best approach to load specific urls (views) in Django project
I have a Django app that exposes the following views: A,B,C...Z. This app is deployed on MACHINE-1. There was a new business requirement to deploy on MACHINE-2 the same Django app but with a subset of those views, let's say A,B and C. My simple solution was to set a config variable (RUN_ON_MACHINE_2=True for the second case and False for the first case). In conclusion, the urls.py file looks something like below (Please do note that I assimilate the views with paths here just to make it shorter): urlpatterns = [A, B, C, ... Z] # If the env var is set to True then only load a subset of the views if config.RUN_ON_MACHINE_2: urlpatterns = [A, B, C] The tests work fine cause they are always executed for [A,B,C ... Z] which of course include [A, B, C]. However, some new business requirements are asking to make changes on view A. I could implement the changes in view A branching the code by the config.RUN_ON_MACHINE_2 variable but I reached the conclusion it's much cleaner to create a new view, A_ForMachine2, which implements only the needed stuff for MACHINE_2. A_ForMachine2 must have the same interface as view A and must … -

Angular service invoking Django method to connect to a MongoDB database
I have written a service script in my Angular app that adds consumer form info to a local Json-Server database: import { HttpClient, HttpHeaders } from '@angular/common/http'; import { Injectable } from '@angular/core'; import { Observable } from 'rxjs'; import { Post } from '../models/post.model'; const httpOptions = { headers: new HttpHeaders({ 'Content-Type': 'application/json' }) } @Injectable() export class DbService { consumersApiUrl = "http://localhost:3000/consumers"; constructor(private httpClient: HttpClient) { } addConsumer(post: Post): Observable<Post> { return this.httpClient.post<Post>(this.consumersApiUrl, post, httpOptions); } } This works perfectly... I have now set up a Django backend and a MongoDB database. In my settings.py file, I have my database connection: DB_NAME = 'mongodb+srv://User2021:TestPassword@cluster0.j9jz1.mongodb.net/test' So, I added a new url and a new method to write the info to my database: @Injectable() export class DbService { consumersApiUrl = "http://localhost:3000/consumers"; consumersMongodbApiUrl = "http://localhost:8000/consumers/"; constructor(private httpClient: HttpClient) { } addConsumer(post: Post): Observable<Post> { return this.httpClient.post<Post>(this.consumersApiUrl, post, httpOptions); } addConsumerMongodb(post: Post): Observable<Post> { return this.httpClient.post<Post>(this.consumersMongodbApiUrl, post, httpOptions); } } In the MongodbApiUrl, consumers is the name of my database collection. My first question: Should the link to a real database (whose connection string and name and collection name I know) be like this or should I somehow include the extra info … -
Django - Simple Task list with checkmarks
I have the following django models: class Tasks(models.Model): date_created = models.DateTimeField(auto_now_add=True) date_changed = models.DateTimeField(auto_now=True, auto_now_add=False) title = models.CharField(verbose_name=_('Title'), max_length=50) content = HTMLField(verbose_name=_('Content'), max_length=8000) class TasksStatus(models.Model): date_created = models.DateTimeField(auto_now_add=True) date_changed = models.DateTimeField(auto_now=True, auto_now_add=False) task = models.ForeignKey(Tasks, on_delete=models.SET_NULL, null=True, related_name="task_status") user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name="task_user_id", on_delete=models.CASCADE, verbose_name=_("User")) checked = models.BooleanField(default=False, null=True, verbose_name=_("Checked")) On a template i want to post all tasks which exists and give the user the possibility to checkmark each task. This is already written to the database by a ajax view: class UpdateTaskStatus(LoginRequiredMixin, View): def dispatch(self, request, *args, **kwargs): return super(UpdateTaskStatus, self).dispatch(request, *args, **kwargs) def post(self, request): task_id = request.POST.get("task_id") task_status = request.POST.get("task_status") task = Tasks.objects.get(id=task_id) if (task_status == "0"): task_status = True else: task_status = None object, created = TasksStatus.objects.get_or_create(user=request.user, task=task) object.checked = task_status object.save() tasks = Tasks.objects.all() tasks_completed = TasksStatus.objects.filter(user=request.user, checked=True).count() if (tasks.count() != 0): if (tasks_completed != 0): tasks_completed = int(round((tasks_completed / tasks.count()) * 100, 0)) return JsonResponse({"task_id": task_id, "task_status": task_status,"tasks_completed": tasks_completed, "msg": "Task status updated."}) The view which comes to the template is this one: @login_required def participation_dashboard(request): user = request.user if user.groups.filter(name='teacher').exists(): defaultTagGenerator(user) dt = timezone.now() all_data = request.GET.get('filter', None) days_dict = {0: 1, 1: 2, 2: 3, 3: 4, 4: 5, 5: 6, 6: … -
How can I modify radio button field in Django to suit my preference?
models.py: class Person(models.Model): GENDER_SELECT = ( ('f', 'Female'), ('m', 'Male'), ('o', 'Other'), ) TITLE_SELECT = ( ('0', 'Mr.'), ('1', 'Mrs.'), ('2', 'Ms.'), ('3', 'Mast.'), ) title=models.CharField(max_length=5,choices=TITLE_SELECT) name=models.CharField(max_length=100) gender=models.CharField(max_length=11,choices=GENDER_SELECT) forms.py: class PersonForm(ModelForm): class Meta: model=Person fields='__all__' widgets={ 'title': forms.RadioSelect(), 'gender': forms.RadioSelect(), } template: <form action="" method="post"> {% csrf_token %} {{form1.as_p}} <input type="submit" value="Submit"> </form> Output: As you can see, the fields display as verticals whereas I want them horizontal. Plus, I don't want that initial '__________' choice. How can I achieve it?
