Customer premissions based on Membership plan
Hi All, I am working on hands-on Django web application, and for this i have to provide access to some videos; products based on the Customer Membership plan. Like if a Customer is in Basic Plan, then allow only to view 10 videos or so.. and for Permium Customer, no limit. For such type of requirement, i was trying to create a model class as Customer_membership which will be a one-to-one relationship with my custom Customer model class. Please suggest, on view and templates how will i be restrict the customer based on their plan. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django - PrePopulate the Foreign Key on the web page, and use that id to save the model.
Hi All,
I am facing an issue, to pre-populate the Foreign Key on the web page.
Actually i have two models Projects and Modules.
To create a Module, one has to select the Project and go to Module page for
create it, but there the Project is not populated.
Below are the details... Please guide me.
*models.py*
class Project(models.Model):
name = models.CharField(max_length = 200, null = True)
startdate = models.DateTimeField()
def __str__(self):
return self.name
class Modules(models.Model):
project = models.ForeignKey(Project, null = True, on_delete =
models.SET_NULL)
modulename = models.CharField(max_length = 200, null = True)
modulestartdate = models.DateTimeField()
def __str__(self):
return self.modulename
*forms.py*
class ProjectForm(forms.ModelForm):
class Meta:
model = Project
fields = '__all__'
class ModuleForm(forms.ModelForm):
class Meta:
model = Modules
fields = '__all__'
*views.py*
def projectView (request):
if request.method == 'POST':
form = ProjectForm(request.POST)
if form.is_valid():
form.save(commit=True)
return render(request, 'budget/projectForm.html', {'form': form})
else :
form = ProjectForm()
return render(request, 'budget/projectForm.html', {'form': form})
def modulesView (request, projectid):
project = Project.objects.get(pk=projectid)
if request.method == 'POST':
form = ModuleForm(request.POST)
if form.is_valid():
form.save(commit=True)
return render(request, 'example/modulesForm.html', {'form': form})
else :
form = ModuleForm(instance=project)
return render(request, 'example/modulesForm.html', {'form': form})
*urls.py*
path('testproject/', views.projectView, name='projectView'),
path('testprojectmodule//', views.modulesView,
name='modulesView'),
in html forms for both Project and Modules... just using {{ form.as_table
}}.
Now after createing the Project, i used the url as
http://127.0.0.1:8000/testprojectmodule/1/
then my Project should get pre-populated... as reached using the project id
which is 1 in this case, but i am getting full drop-down. Refer attached
image.
Either the Project should be pre-selected.. or can make it non-editable
either will work for me.
Please help.

django dependent drop down list without using javascript; ajax; jquery
Hi All, Could any one please share some details on how we can do dependent drop down list selection. I am seeing lot of videos or content to handle this via JavaScript; AJAX; jquery etc.. but just wondering if Django has anything which can be handled easily. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django - What is the best approach to handle multiple user types…and route the HTML pages based on this?
I'm making a small test project with below user types: School Admin,
Teacher, Student, Parent. And each user type will have different
Permissions like School Admin has full access... Parents can only view
their Childern's Activity. Teacher can see all students but can add / edit
marks for their respective students only. Teachers can setup Exam etc..
Students can take exam and submit the exam, but cannot edit / add any other
information. Just can edit his profile detail.
Approach 1: Do i need to create a Custom User calss and apply to each user
type (ie one Custome Class.. and 4 user type calss).. and similarly have 4
different view and html pages?
Approach 2: Just have one custome class and have an field with UserType
which will have the have as "SchoolAdmin", "Teacher", "Student","Parent"..
and one view and html (as the data page would remain same and only data
record will restrict), and somehow identify the User Type in View, and
filter the record?
Definately some view or html pages will be specific to one user type only
which is i am able to handle, the issue is to use same view / html page to
handle all user type.
Please suggest... and any code snippet will will more helpful.
Below is the thing from approach 1, i was trying.
# models.py-class CustomUser(AbstractUser):
USER_TYPE_CHOICES = (
('SchoolAdmin'),
('Teacher'),
('Student'),
('Parents'),
)
user_type = models.CharField(blank=False, choices=USER_TYPE_CHOICES)
name = models.CharField(blank=False, max_length=255)
country = models.CharField(blank=False, max_length=255)
city = models.CharField(blank=False, max_length=255)
phone = models.CharField(blank=True, max_length=255)
created_at = models.DateField(auto_now_add=True)
def __str__(self):
return self.name
class SchoolAdmin(models.Model):
user = models.OneToOneField(
CustomUser, on_delete=models.CASCADE, primary_key=True)
class Teacher(models.Model):
user = models.OneToOneField(
CustomUser, on_delete=models.CASCADE, primary_key=True)
photo = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True)
class Student(models.Model):
user = models.OneToOneField(
CustomUser, on_delete=models.CASCADE, primary_key=True)
teacher = models.ForeignKey(Teacher)
photo = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True)
class Parent(models.Model):
user = models.OneToOneField(
CustomUser, on_delete=models.CASCADE, primary_key=True)
student= models.ForeignKey(Student)
