Different types of URLInput Django form fields
URLField
The default widget for this input is the URLInput. Uses an URLValidator to verify that a given URL is a valid URL or not. Empty value is an empty string(”). It normalizes to a String.
There are two optional arguments for validation, max_length, and min_length. If provided, this argument ensures that the string has a maximum or minimum given length is the same as CharField.
Syntax: URLField(**kwargs)
Example:
from django import forms
class URLInputForm(forms.Form):
url= forms.URLField(label='Enter URL', label_suffix = " : ",
required = True, disabled = False,
widget=forms.URLInput(attrs={'class': 'form-control'}),
help_text = "Please provide a valid URL.",
error_messages = {'required':"Please provide valid URL."})Let’s run the server and check the result.

Explanation:
| Field Options | Description |
|---|---|
| label | The label argument allows you to specify a “Field Caption” label for this area. |
| label_suffix | The label_suffix argument allows you to insert some text after the field’s label. |
| min_length | Ensures minimum label length. |
| max_length | Ensures maximum label length. |
| required | By default, each field assumes a value as required, so you need to set required = false to make it not necessary. |
| widget | Widget Argument lets you specify widget classes to use when presenting this field. So you can use bootstrap class or other CSS class for this field to decorate your field. Also, you can pass the choice list. For eg. url = forms.URLField(widget=forms.URLInput(attrs={‘class’: ‘form-control’})) |
| error_messages | error_messages argument allows you to overwrite the default error message that the field will raise. Pass the error message you want to overwrite in the dictionary with matching keys. |
| disabled | Disabled Boolean Argument, when set to true, disables the form field using the disabled HTML attribute so that it cannot be edited by users. |
