Unable to resolve keyword 'i' in field. The following options are possible: id, join_on, user, user_id
I don't understand what I am doing wrong. I am trying to update a model through a form and I am following a tutorial online, they all point to get the id. I did this, but I keep getting this error:
Unable to resolve keyword 'i' in field. Possible options: id, join_on, user, user_id
the id key is there, but it thinks it is "me" what I'm looking for.
Any idea?
view.py
def testRegistration(request):
id = UserProfileModel.objects.get('id')
user_status_form = UserDetailsForm(request.POST or None, instance=id)
if request.method == 'POST':
if user_status_form.is_valid():
user_status = user_status_form.save(commit=False)
user_status.user = get_user(request)
user_status.save()
user_status_form = UserDetailsForm()
else:
user_status_form = UserDetailsForm()
return HttpResponseRedirect('testRegistration')
return render(
request, 'registrationTest.html',
{'user_status_form' : user_status_form,
}
)
model.py
class UserProfileModel(models.Model):
user = models.OneToOneField(User, unique=True)
joined_on = models.DateTimeField(auto_now=True, null=True)

There is an error in your view on this line,
id = UserProfileModel.objects.get('id')
Replace it with something like this,
id = UserProfileModel.objects.get(user__username=request.user.username)
objects.get
the method takes field_names and values as keyword arguments and returns an object with a match condition. From your perspective, I assume you want to get the UserProfile of the current loggedin user. To do this, you need to access the user's field identifier (ForeignKey to User) and map it to the current user (request.user).
