Didn't see any time difference in django async and sync view?
I'm new to django and async programming. So just for testing. I tried this code in django but I didn't see any any time difference. Sample code def sync_view(request): print('Called Sync View') start_time = time.time() context = dict() time.sleep(5) print('First time sleep') time.sleep(5) print('Second time sleep') print('Time Consumed', time.time()-start_time) return render(request, 'sync.html', context) async def async_view(request): print('Called Async View') start_time = time.time() context = dict() await asyncio.sleep(5) print('First time sleep') await asyncio.sleep(5) print('Second time sleep') print('Time Consumed', time.time()-start_time) return render(request, 'async.html', context) and here is console output. To setup async environment I followed this tutorials https://testdriven.io/blog/django-async-views/ Do i really need to use uvicorn in local environment? Here I'm using uvicorn in my local environment,so i used this command to start the server (env)$ uvicorn hello_async.asgi:application --reload and My last question. After releasing django3 do i really need django channels for chat application and django celery for running task in the background. -

How to add ChoceField to Django forms for regustration user
I am making a registration form for 3 types of users. When a user enters email and password he/she must select one of the roles. First I used BooleanFields and it works, but more than one checkbox can be selected. I need that user can select only one role. I have tried ChoiceField, which I could display on the template but it does not POST any data to db. forms.py class RegisterForm(forms.ModelForm): """A form for creating new users. Includes all the required fields, plus a repeated password.""" password1 = forms.CharField(label='Password', widget=forms.PasswordInput) password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput) parent = forms.BooleanField(label="I am a Parent") school = forms.BooleanField(label="I am a School Admin") vendor = forms.BooleanField(label="I am a Vendor") role_select=forms.ChoiceField( widget=forms.RadioSelect, label="Select your role.", choices=(('is_parent','parent '),('is_school','school'),('is_vendor','vendor')), ) if not parent and not school and not vendor: raise forms.ValidationError("Users must have a role") class Meta: model = User fields = ['role_select', 'parent', 'school', 'vendor', 'email'] #'full_name',) def clean_password2(self): # Check that the two password entries match password1 = self.cleaned_data.get("password1") password2 = self.cleaned_data.get("password2") if password1 and password2 and password1 != password2: raise forms.ValidationError("Passwords don't match") return password2 def save(self, commit=True): # Save the provided password in hashed format user = super(RegisterForm, self).save(commit=False) user.set_password(self.cleaned_data["password1"]) user.role_select( self.cleaned_data['role_select']) # … -
Django redirect_url with parameter
I have a simple UpdateView which updates instances of my Profile model. class ProfileUpdateView(UpdateView): model = Profile fields = ['first_name', 'last_name'] It's working fine both GET and POST, but since the GET uses an url parameter, I want also the redirect_url to redirect to the updated profile. My current urls.py: from profiles.views import ProfileUpdateView urlpatterns = [ path('self/<slug:slug>', ProfileUpdateView.as_view(success_url='/'), name='self_profile') ] It is currently redirecting to the main url, but I don't figure out how to make the redirect_url parameter redirect to the profile modified on the handled POST. Let's say I do http://localhost:8000/profiles/self/demo, (GET), then I modify my first_name and submit the request. I want the redirection to go to /profiles/self/demo again. I know I could override def post() on the view and achieve it, but since I only want to deal with the redirection I wanted to know if exists any other elegant solution. EDIT: Additional info: the slug url parameter will always be request.user in this case (since I use other view (a DetailView) to see other users' profiles). Thanks!! -

Customising the fields of drop-downs in Django w.r.t to conditions
I have a scenario where I have 2 drop-downs and the values of second drop-downs are based on the first drop-downs values. For example :- According to my implementation write now it appears to be 2 separate drop-downs drop-down1_value 1 drop-down1_value 2 drop-down1_value 3 drop-down2_value 1 drop-down2_value 2 drop-down2_value 3 drop-down2_value 4 What I want is the value should appear as drop-down1_value 1 drop-down2_value 1 drop-down2_value 2 drop-down1_value 2 drop-down2_value 3 drop-down2_value 4 so, basically the values of drop down 2 are dependent on the values of drop down 1. Internally the tables are connected but I am not able to display it as required. It has to be done something with Django forms as per my research but I am not able to do it. Any help will be really very helpful. -

Django web service stack and concepts questions
I need to develop a web service with RESTful API on Django. I would be grateful if someone could clarify a few questions and point me in the right direction. It has to connect to a remote database and perform long queries and then return the rows to a user (I plan on returning csv files) I chose Django as a framework, but I am a bit lost with all the things I read Since queries take a long time to finish , the service should somehow work in async. The async concept in regards to web services especially in connection to Django is really complicated to grasp. Would using new Django 3.x async features be enough for this task? I've read about Celery the queue manager that is supposed to provide some degree of parallelisation (am I correct on this?) I've also read about nginx + wsgi + Django. Should I go with that? In regards to nginx and other web servers. Am I correct in understanding that Django in itself can function as a web server, but nginx can be used to somehow better the performance of a Django application? Should I use "django rest framework" for the … -

Django Queryset filter equivalency to SQL
To me, it is not clear or lack of example code to understand the documentation about how SQL language is internally used in Django ORM. My intended SQL is: SELECT projects_category.id, projects_category.name, projects_project.name FROM projects_category JOIN projects_project_categories ON projects_category.id = projects_project_categories.project_id JOIN projects_project ON projects_project_categories.project_id=projects_project.id WHERE NOT projects_project.is_mini ORDER BY projects_category.id; How to do the same in Django ORM or in Django view?

Also, any other tricks would be appreciable. -
