How to access a specific user's model data as admin?-CodePudding

I'm creating a simple model form that is only available to staff. It has a user selection dropdown list populated by models.py user = models.ForeignKey(User, on_delete=models.CASCADE).

On submit I need my view to look up the selected user from the form and return the data in the models for that user (from the built-in Django database). How would I go about doing this?

I have searched here and the recommended articles, but they all appear to be for accessing a model as the logged-in user. Here is a screenshot of the form and my code:

models.py

class GetData(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)

forms.py

class DataRequestForm(forms.ModelForm):
    class Meta:
        model = GetData
        fields = ['user']

Views.py

@login_required
def data_form(request):
    if request.user.is_staff == True:
        if request.method == 'POST':
            form = DataRequestForm(request.POST)
            if form.is_valid():
                user = request.POST["user"]
                print("Form is Valid")
                print(user) 
                # How to access that user's model data here?

CodePudding user response：

You should first get user by id then get model details using that retrieved user.

views.py

@login_required
def data_form(request):
    if request.user.is_staff == True:
        if request.method == 'POST':
            form = DataRequestForm(request.POST)
            if form.is_valid():
                user = request.POST["user"]
                print("Form is Valid")
                print(user) 
                
                # getting user data by id.
                get_user = get_object_or_404(User, id=user)

                get_another_model_data = SecondModel.objects.filter(user=get_user)

                # perform or save the data here
