Model Required Field Deed For Free

In order to make a field optional, we have to say so explicitly. If we want to make the pub_time field optional, we add blank=True to the model, which tells Django's field validation that pub_time can be empty.

When set to a particular value the option used appends some validations to the field as required by the developer. Let's try to use required via Django Web application we created, visit and try to input the value based on option or validation applied on the Field. Hit submit.

What are required form fields? To put it simply, a required form field must contain an answer before the respondent can submit the form. These are fields that absolutely must be answered in order for the form to be useful. It's possible for a form to be useful without having any required fields.
