How to populate a form from an instance in model when the form is using Form instead of ModelForm?
Title
Question
I am making a Django project where users can sign up, sign in, view their profile and change it if they want to.
I want to know how to implement the functionality of a user changing their profile?
Here is my user form in forms.py
```
class CustomerForm(forms.Form):
username = forms.CharField(label='Desired Username', max_length=150, validators=[validate_username])
first_name = forms.CharField(label='First Name', max_length=150)
last_name = forms.CharField(label='Last Name', max_length=150)
email = forms.EmailField(label='Your Email', validators=[validate_email])
password1 = forms.CharField(label='Enter Password', widget=forms.PasswordInput, min_length=8)
password2 = forms.CharField(label='Retype Password', widget=forms.PasswordInput, min_length=8)
def clean(self):
cleaned_data = super().clean()
password1 = cleaned_data.get("password1")
password2 = cleaned_data.get("password2")
if password1 != password2:
raise ValidationError(
"Passwords do not match"
)
```
Here is my sign-up method in views.py
```
"""Function for sign up."""
def sign_up(request):
if request.method == 'POST':
form = CustomerForm(request. POST)
if form.is_valid():
try:
user = User.objects.create_user(
request.POST['username'],
request.POST['email'], request.POST['password1']
)
user.first_name = request.POST['first_name']
user.last_name = request.POST['last_name']
user.save()
request.session['normal_username'] = request.POST['username']
login(request, user)
return redirect('../book/')
except Exception:
return HttpResponse("Something went wrong. Please try again.")
else:
context = {'form': form}
return render(request, 'sign_up.html', context)
context = {'form': CustomerForm()}
return render(request, 'sign_up.html', context)
```
<a href="https://docs.djangoproject.com/en/1.8/_modules/django/contrib/auth/forms/" target="" title="UserCreationForm">I cannot user UserCreationForm because it is depreciated.</a>
The main problem that I am facing is that I cannot populate the form using 'instance' parameter since I am using Form instead of ModelForm. Is there a way to populate the form?
```
"""Function for editing profile."""
def edit_profile(request):
profile = User.objects.get(username=request.session['normal_username'])
if request.method == 'POST':
form = CustomerForm(request.POST, instance=profile)
if form.is_valid():
form.save()
return redirect('../book/')
else:
context = {'form': form}
return render(request, 'sign_up.html', context)
context = {'form': CustomerForm(instance=profile)}
return render(request, 'edit.html', context)
