Registration: Making View & Editing Model Form Clean Method to Check Passwords
I don't understand the exact meaning of field error and non-field error from password and email fields as both are mentioned in the registration form.
kindy elaborate in a concise way
In Django, field errors and non-field errors are different, depending on where the validation happens and what kind of validation it is. Here’s a simple explanation:
Field Errors
- These are errors linked to specific fields in the form.
- They occur when the data entered in a field doesn’t meet the required conditions.
Examples:
- The password is too short.
- The email field is empty or contains an invalid email.
If you submit the form with an invalid email or a password shorter than 8 characters, you’ll see field-specific error messages like:
- Email: “This field is required.”
- Password: “Ensure this value has at least 8 characters.”
Non-Field Errors
- These errors apply to the form as a whole, not a single field.
- They happen when validation depends on the relationship between fields or when the error doesn’t belong to just one field.
Examples:
- Password and confirm password do not match.
- The email address is already registered.
Even though the registration form includes email and password fields, field errors and non-field errors work in their own distinct ways.
I hope this explanation makes things clearer. If you still have any doubts, feel free to ask, and I’ll try to explain in more detail.
