Random password generation when admin creates employees in admin site
I have inherited three users from the User model, namely the Admin, Employee, and Relative. models.py config = RawConfigParser() config.read('config.cfg') class UserManager( BaseUserManager): def _create_user(self, PAN_ID, password=None, **extra_fields): """ Creates and saves a User with the given email, date of birth and password.

How to exclude an item in Django loop?
Hopefully just a quick question. I am having some difficulty wrapping my mind around to using Django loop function. I have a simple page which is fetch some data from db. Everything seems fine although loop function melting my mind. Simply my loop: {% if books %} {% for reader in books %} {{ reader.title }} {{ reader.booknumber|default_if_none:"" }} {% endfor %} {% else %} My result like: Elena 141 Elena M.Mary 1035 P.Paul 141 P.Paul T.Mark 741 T.Mark T.Mark My Expect result like: Elena 141 M.Mary 1035 P.Paul 141 T.Mark 741 Thats because some of booknumber cell is emtpy in my db. I just wonder how do i put them out of loop? I'm using defult_if_none func for hide "None" but didnt find a way for hiding\excluding title (if doesnt have booknumber). I really appreciate if someone could help me out. Thank you in advance. -
Writing Customized functions in django views
how can I return error from a python function and display it in Django temaplate. I have a code base that is similar to the following structure: In Views.py: def calculate(num1, num2): result = int(num1) + int(num2) return result def home(request): if request.method == POST: user_input_1 = request.POST.get('user_input_1 ') user_input_2 = request.POST.get('user_input_2 ') calculator = calculate(user_input_1 , user_input_2 ) context = { 'calculator' : calculator } return render(request, 'home.html', context) return render(request, 'home.html') So in the case were the user enters a letter instead of a digit, I want to display an error in the django template telling the user about the error. Right now when error occurs the code crashes. I know that I can write a try and except to handle the error but I don't know how to display the exact error message on the HTML template. Any Ideas on how to go about this please? -
How to set token expiration time according to user type in django-graphql-jwt?
Let's say we have two type of users, bot users and normal users: class User(AbstractBaseUser, PermissionsMixin): username = models.CharField(max_length=255, unique=True) is_bot_user = models.BooleanField(default=False) USERNAME_FIELD = 'username' REQUIRED_FIELDS = [] objects = CustomUserManager() We would want to set longer expiration time to bot user when it logs in. In settings.py we must define JWT_EXPIRATION_DELTA GRAPHENE = { 'SCHEMA': 'app.schema.schema', 'MIDDLEWARE': [ 'graphql_jwt.middleware.JSONWebTokenMiddleware', 'debugging.middleware.DebugMiddleware' ], } GRAPHQL_JWT = { 'JWT_VERIFY_EXPIRATION': True, 'JWT_EXPIRATION_DELTA': timedelta(minutes=10), } How this expiration delta can be varied according to the Users is_bot_user field? Or is there some other way to create different type of tokens for different Users -

How to manage mobile and web authentication with Django Rest and react/react native?
We are in the process of setting up a project that requires mobile and web app authentication and were wondering if there are any best practices for implementation. For the backend we are currently using django rest framework with a knox token authentication and for the web frontend react.js. For the future, there will be a mobile app in react native. We want to set up the authentication now so that it supports the react native mobile app in the future. However, I have seen that Knox authentication does not work for mobile apps straight forward as it uses csrf token. So I'm wondering if there are any best-practices for mobile app and web authentication that specifically feature good documentation, multi-device login and smooth extensibility of login options (fb, google etc) for the current setup drf and react.js/react native. I'm grateful for any guiding hints. -

PostgreSQL HStore() field
I use multiple PostgreSQL HStore fields in my django model. Keys of HStore fields are big int numbers that are related to some other fields in application and are therefore random, not predefined. Values are decimal numbers. Like so: "10intNumber" => "DecNumber". All hstore fields have the same 10IntNumber keys in them, even if DecNumber is 0. The model also include a foreign key to user, and a status. Status is 1: only the hstore_field_1 is evaluated and summed. Status is 0: both hstore_field_1 and hstore_field_2 are evaluated and summed. I use a SQL Query like this, to sum all the DecNumber in values for predefined 10intNumber, where d.number is the 10IntNumber from before and is retrieved from another queryset.: query = f""" SELECT SUM(hstore_1::numeric) AS hstore_1_field, SUM(hstore_2::numeric) as hstore_2_field, FROM ( SELECT UNNEST(hstore_field_1-> ARRAY {[str(d.number) for d in queryset]}) AS hstore_1, UNNEST(CASE WHEN status = '0' THEN hstore_field_2-> ARRAY {[str(d.number) for d in queryset]} ELSE ARRAY ['0'] END) AS hstore_2, FROM public.app_model WHERE hstore_field_1?| ARRAY {[str(d.number) for d in queryset]} ) AS b; """ I also use a SQL query to group sums by related user_id and user__othemodel_id.

In Django what does the request argument in a method do?
I have seen a few codes where sometimes the authenticate method have the request argument while other times it does not, e.g. see the below codes: Code 1: def register(request): if request.method == 'POST': form = UserCreationForm(request.POST) if form.is_valid(): form.save() # code for automatic login after singing up username = form.cleaned_data['username'] password = form.cleaned_data['password1'] user = authenticate(username=username, password=password) login(request, user) return redirect('/') Code 2: def login(request): if request.method == 'POST': username = request.POST['username'] password = request.POST['password'] user = authenticate(request, username=username, password=password) According to the official docs: request is an HttpRequest and maybe None if it wasn’t provided to authenticate() (which passes it on to the backend). What does this request argument actually do and when should I consider passing it in the authenticate or login method? Is there any specific reason for which request argument is present or absent in the above codes? -

How do you access a ForeignKey's other attribute in Django?
I've been looking for a way to retrieve a model's attribute via ForeignKey(related_name). I'm going to paste the code below.

How do i get get the number of existing partners for a specific company? I'm able to get a Company instance then use the related name to get the existing partnerships. If I try something like Company.partnership_creator_set.all(), I'm able to get the list of partnerships. What I want is to look for the current partners which is in the "partner" attribute in the Partnership model. -
