Django Rest Framework: two viewsets for one router
I want to have TWO DIFFERENT viewsets (for example, one implements only the GET method, the other implements only the POST method), but which will have the same url: GET /tournament/ - returns concrete object of the model Tournament; POST /tournament/ - create object of the model Tournament. But it is important that they must have the same url /tournament/! I trying something like this: models.py class Tournament(Model): ... viewsets.py class PublicTournamentEndpoint( mixins.RetrieveModelMixin, mixins.ListModelMixin, viewsets.GenericViewSet ): queryset = Tournament.objects.all() authentication_classes = [] # empty! class PrivateTournamentEndpoint( mixins.CreateModelMixin, viewsets.GenericViewSet ): queryset = Tournament.objects.all() authentication_classes = ['SomeAuthBackend'] # not empty! routers.py class TournamentRouter(SimpleRouter): routes = [ Route( url=r'^{prefix}/tournament/$', mapping={ 'get': 'retrieve', 'post': 'create', }, name='{basename}', detail=True, initkwargs={}, ), urls.py tournament_router = TournamentRouter() tournament_router.register( 'tournaments', PublicTournamentEndpoint, basename='tournaments', ) tournament_router.register( 'tournaments', PrivateTournamentEndpoint, basename='tournaments', ) urlpatterns += tournament_router.urls But my urlpatterns has next values: [ <URLPattern '^tournaments/tournament/$' [name='tournaments']>, <URLPattern '^tournaments/tournament/$' [name='tournaments']> ] and so when I send a POST /tournament/ request, I get the following error: 405 "Method \"POST\" not allowed." because the first match url does not have a POST method, but only GET. How can i resolve this problems? Thank you! -
How can I relate some, but not all, models to users using Django?
I have a project which includes two different apps: users and school. In my current implementation, the users app contains a custom user class derived from Djagno's AbstractUser. It defines allowed user types as student or teacher, and the user must select one during registration. The school app contains a classroom model which I need to relate to students and one or more teachers. I have two main problems here. The first is regarding how to relate the classroom model to only specific users restricting their access based on their user type. I have tried using a ManyToManyField relation in the classroom model in order to associate the instance with the user who created it (and then I would later allow the user to add students). It appears I don't understand this field correctly -- it actually all users to all classroom instances. This obviously does not meet my requirement to restrict access among different classroom instances. OneToOneField and ForeignKey do not seem to meet my needs either. I have tried adding those fields to my user, but then I am restricted to a single classroom per user which is not acceptable either. I have also played around with creating … -
How do I create a queryset to display products that are linked to a category, that is shown by each category slug?
I have a product model and a productcategory model. The products are linked to the productcategory by a category attribute. I want to create a query that displays ONLY products that are in a category, when the webpage is displayed for that specific category. The way I have my views currently setup, I get an attribute error, saying the view has no attribute of slug.

Django apps shared python api client
Let's say I have an external python client that I use as a data source. Let's call it api. It's a pretty standard API, so creating a session object is easy and allows you to connect to the data source. I have a few Django apps that will depend on this api, and I'd like to have as few handles to this api per site as possible (one per process I'm guessing). I was thinking of two approaches: Write a non Django slim wrapper around my API implementing the singleton pattern, with one session object per site. Use it in my Django apps. Write a Django app with a custom signal that sends the instance once connected. It's one of these the best approach, or is there a more ad hoc way? -

In Django, how do I enable users to join a group if the user knows the group password?
In Django I'd like to allow logged-in users to join a group if they enter the right PIN/password. Users should not be able to see what groups exist, instead the user enters a PIN and if that PIN matches the PIN for an existing group, then the user becomes a member of that group. Most of the answers I find are related to user authentication. class Group(models.Model): name = models.CharField(max_length=16) pin = models.IntegerField(unique=True) members = models.ManyToManyField(User, related_name='members', blank=True) Using the model above, I'd like any user who enters a pin that matches an existing pin to become a member of the corresponding group. I'm also open to other ways to structure this, if you can offer a recommendation. I'd like to avoid inviting users to join the group via email or other ways. -
Learning more advanced object oriented patterns in python
Hopefully this question will be useful to others that are looking into learning better practices in python and will serve as a future resource. What are some good resources to learn more advanced python object oriented programming. For example, understanding patterns such as used in the django source code: class FieldFile(File): def __init__(self, instance, field, name): super().__init__(None, name) self.instance = instance self.field = field self.storage = field.storage self._committed = True def __eq__(self, other): # Older code may be expecting FileField values to be simple strings. # By overriding the == operator, it can remain backwards compatibility. if hasattr(other, 'name'): return self.name == other.name return self.name == other def __hash__(self): return hash(self.name) # The standard File contains most of the necessary properties, but # FieldFiles can be instantiated without a name, so that needs to # be checked for here. def _require_file(self): if not self: raise ValueError("The '%s' attribute has no file associated with it." % self.field.name) -

i am trying to update a profile in profile page and create a form. i import form and use ModelForm but my model is not accepting profile data. and it is showing name error. i can not find suitable answer for this problem. -
he SECRET_KEY setting must not be empty - Even when SECRET_KEY is set in settings.py
I keep getting this error when i try to import my models.py file into views.py or any of the other python script in my App directory, i have the SECRET_KEY in settings.py, i have my app in the list of installed_APPS, wsgi.py contains os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings') - i replaced my project name manage.py also contains os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings') this is all i saw was wrong with other people's installations in all the other stackoverflow posts. My code works but importing models just breaks it i use this command to import my class from app_name.models import suscribers and subscribers is defined thus class subscribers(models.Model): name = models.CharField('Name', max_length=120) email = models.CharField('Email', max_length=120) access_token = models.TextField() expires_in = models.DateTimeField('token expiry date') i have already executed makemigrations and migrate commands but being a newbie i don't know where else to look. Please save a soul its been 3 days thanks.
