how to fetch and return a template in django-javascript
I made a fetch post that includes information i need to handle on my server. So i'm doing: def prepricing(request): if request.method == "POST": if json.loads(request.body): content = json.loads(request.body) return render(request, "letter/pricing.html", { "mail":content['mail'], "name":content['name'], "content2":content['content'] }) This is what is running when the fetch post is done. Clearly this is not working. It's not returning anything. I should be doing instead: return JsonResponse(content) But I want to render that template and pass those variables. Should I return the JsonResponse and handle the template return in JavaScript? How can i do this? I just need to return that template with the values from the fetch POST. -
pytest: How to DRY up similar model manager method tests

Django password form assign widget doesn't work
I'm creating a registration form for my website and everything functions, except the 'password1' and 'password2' won't recognize the widgets I assign to them. Below is a part of my code, which should be relevant to the issue from my forms.py file. Note the email part works correctly. fields = ['password1', 'password2', 'email'] widgets = { 'password1': forms.PasswordInput( attrs={'class': 'form-control', 'placeholder': 'Wachtwoord'} ), 'password2': forms.PasswordInput( attrs={'class': 'form-control', 'placeholder': 'Wachtwoord'} ), 'email': forms.EmailInput( attrs={'class': 'form-control', 'placeholder': 'E-mailadres'} ), } Below is a part of the registration.html in which the form is drawn. The top part is from the last name part which functions normally, the bottom part is from password1 which doesn't function: <div class="col-md-6"> <label for="last_name" class="text-info"> {{lid_form.last_name.label}}</label> {{lid_form.last_name}} </div> </div> <div class="row"> <div class="col-md-6"> <label for="password1" class="text-info"> {{user_form.password1.label}}</label> {{user_form.password1}} </div> Picture Example -

How to make a like button with jquery inside a form so that it will save it to database and also change the style of like button?
I am working on a django project and I want to add a like button to the posts. this is my template: <form action="{% url 'like' post.id %}" method="GET" name="liked" class="l-form"> {% csrf_token %} <button style="display: inline;" class="like__btn"> <i class="like__icon fa fa-heart" style="display: inline;"></i> </button> </form> <script> $('.like__btn').on('click', function(){ $('.like__icon.fa-heart.fa').toggleClass("liked"); }); </script> All I want to do this, when user clicks on a heart icon, it will submit the form. But also change the icon color to red. (liked class is basically, color:red) When I click on the button it submits the form, increases the like count, but then it refreshes the page so my heart icon doesn't stay red. If I add type="button" this time it doesn't refresh the page, change the color of the icon but doesn't submit the form. I tried to do another button to submit the form and make it hidden but whenever the form is submitted it refreshes the page and goes back to the white heart. Also tried to return false; in jquery but it doesn't submit the form again. I am stuck for hours, so any advice would be great! -
Should race conditions be handled in form or view?
Lets suppose I have to withdraw money from a specific wallet object. So I first check if x amount of money is in wallet.. Then I lock wallet object in form clean() method, then check it. If the wallet has enough money, form is valid and we proceed to the view. In the view the withdraw action happens but in the view, the wallet object won't be locked anymore.. If two threads manage to reach to the view at the same time, race condition may occur. should the transfer action happen in the clean() form method where the wallet object will be locked or validate the amount of money of the wallet in the view? -

How to prevent websockify process spawned by Django process does not get killed when restarting UWSGI?
I have the following oversimplified code: def openvnc_connection(request): Popen(['websockify', ...]) ... Problem is when I deploy the code, involves restarting the uwsgi service, the websockify process gets killed as well, resulting any active vnc connection gets dropped. I am aware the websockify process is the child of the django process and it gets killed because of that. I have tried the double-fork or similar stuff like detaching the child process but they don't seem to work. -
limit_choices_to with Q objects not working in production
I have these models where a Person can be a player, and if so, can be added to a team. I had the following code working in development, but in production it raises the error (requirements are exactly the same, but production as python 3.6.9 and development has python 3.7.3): Cannot resolve keyword 'is_active' into field. Choices are: players, < and the remaining fields of Team> The code models.py class Role(models.Model): role = models.CharField(max_length=30, verbose_name='Função') is_active = models.BooleanField(default=True, blank=False, null=False, verbose_name='Ativo') class Person(models.Model): name = models.CharField(max_length=150, verbose_name='Nome Próprio') roles = models.ManyToManyField(Role, blank=True, verbose_name="Funções") is_active = models.BooleanField(default=True, blank=False, null=False, verbose_name='Ativo') #...other non relevant fields class Team(models.Model): #...other non relevant fields players = models.ManyToManyField('Person', blank=True, verbose_name='Jogadores', limit_choices_to=Q(roles__role__startswith='player', roles__is_active=True, is_active=True )) # The above Q means Person's whose role starts with 'player' AND the role is active AND the Person is also active This works great in development but not in production...

Why is the Django Admin bad for multiple users
I'm trying to find out why Django Admin is bad to use for users around > 10000 users and why people insists that I should serialize with for example Django REST API and use JavaScript on frontend to handle the data. Why is that? Why do I need to focus on that when the Django Admin is functioning well enough for my and the users needs? -
Is it possible to create an alias for deep joins/relationships?
I am adding some functionality to an app where a user can sort records in a table on the frontend (react) by passing additional url parameters to the backend. We use this in several places, and have a Mixin for pagination. In the pagination mixin I have the following: def get_queryset(self): order_by_field = self.request.GET.getlist("order_by") if order_by_field: return super().get_queryset().order_by(*order_by_field) else: return super().get_queryset() This works great, I can pass urls like {app_base_path}/{some_resource}/?order_by=title to get it to sort the returned query set by the queried model's title field. It also works with multi-sort (e.g. {app_base_path}/{some_resource}/?order_by=title&order_by=date). However, this looks very ugly and reveals unneccessary information to the end user for deeply nested relationships. For instance if I want to sort by a related field through an intermediary table: {app_base_path}/{some_resource}/?order_by=intermediary_model__related_model__field_of_interest. Is there a way I can make this nested relationship an alias on the model I am querying? Something like: class MyModel(models.model): # other model fields, etc. @property def alias(): return "intermediary_model__related_model__field_of_interest" -
