I create a model:
class Person(models.Model):
name = models.CharField(max_length=250)
slug = AutoSlugField(populate_from='name')
birth_date = models.DateField(null=True, blank=True)
blood_group = models.CharField(max_length=5)
present_address = models.CharField(max_length=250, blank=True)
permanent_address = models.CharField(max_length=250, blank=True)
user = models.OneToOneField(
settings.AUTH_USER_MODEL,
related_name='member_persons')
forms.py:
class MemberForm(ModelForm):
class Meta:
model = Person
exclude = ('user',)
def save(self, request, commit=True):
person = super().save(commit=False)
if not person.pk:
person.user = get_user(request)
if commit:
person.save()
self.save_m2m()
return person
It worked fine for first person create. When same person again try to submit create form with different data it gives 'save() missing 1 required positional argument: 'request''. Full traceback:

I want to show a message "You already submitted data" rather than getting this error. How can I show this message in the person creation form?
Any help will be appreciated.

Do you have any idea why?
You are making a super() call with the wrong parameters, it should be:
def create(self, request, *args, **kwargs):
product_id = self.kwargs['pk']
if Like.objects.filter(user=self.request.user, product_id=product_id).exists():
raise ValidationError(_("This user already likes this product"))
else:
return super().create(request, *args, **kwargs)
The issue is how you're calling create()
Try the below:
In the PythonKuba/api/ecommerce/views.py file
return super().create(request=self.request, product_id=product_id, **kwargs)
At the moment you are sending in the user, not the request

I don´t know if I'm understanding the error correctly and 'carro' is not getting the value.
You are passing the kwarg 'carro' to the view, but not to the form.
In your view, override the "get_form_kwargs" method and return the kwarg.
def get_form_kwargs(self):
kwargs = super(InternalResetPasswordView, self).get_form_kwargs()
kwargs['carro'] = self.kwargs.get('carro')
return kwargs
I have reviewed many questions/answers for hours and applied many techniques but I couldn't pass the user id to the form init() method, it always gives errors like "init() got an unexpected keyword argument 'request'". Anyone knows the reason?
Form, updated as requested in the comment:
class ChildChoreForm(ModelForm):

The problem is that you have set up your form to accept a request argument in __init__, but you are initialising a formset, not a form. You need to modify the formset to accept that same argument and pass it to the forms in the formset:
# First define a base class that overrides __init__ and get_form_kwargs
from django.forms import BaseFormSet
class BaseChildChoreFormSet(BaseFormSet):
def __init__(self, *args, **kwargs):
# Handle the request argument that you are passing on init
self.request = kwargs.pop('request', None)
super().__init__(*args, **kwargs)
def get_form_kwargs(self, index):
kwargs = super().get_form_kwargs(index)
# Add request to the kwargs that are passed to the form on init
kwargs['request'] = self.request
return kwargs
# Now set up your formset using this class
ChildChoreFormSet = inlineformset_factory(
Child, ChildChore, form=ChildChoreForm, formset=BaseChildChoreFormSet, extra=1)

admin.site.register(Employee)
admin.site.register(Project)
I've had this problem myself. I upgraded from Django 1.10 to 1.10.2 and that seems to have fixed it for me. Good luck.
I want to redefine class attribute in derived class. The email attribute is already exists in parent class User, but it's have no unique=True property as I need. I know that Django does not support this feature directly. So I did that:
class CustomUser(User):
"""The inherited User class. Email field are redefined to add the warning
about uniqueness is required. UserManager as the default manager so that
the standard methods are available."""
def __init__(self, *args, **kwargs):
super(CustomUser, self).__init__(*args, **kwargs)
email = models.EmailField(unique=True)
email.contribute_to_class(u'email', self)
objects = UserManager()

Exception Type: AttributeError at /admin/stdapp/customuser/add/
Exception Value: 'CustomUser' object has no attribute 'replace'
What can I do to fix it or how to set unique to True in email field? What the cause of this exception?
Edit:
Another way to do this.
First variation:
class CustomUser(User):
def __init__(self, *args, **kwargs):
setattr(self._meta.fields[4], 'unique', True)
Second:
class CustomUser(User):
def __init__(self, *args, **kwargs):
self._meta.fields[4].unique=True
Both are have the same error: can't set attribute.
