GenericIPAddressField specifies the following optional arguments:
field_name = forms.GenericIPAddressField ( ** options )
GenericIPAddressField illustration using example. Consider a project named
pythonengineering that has an application named
Refer to the following articles to check how to create a project and an app in Django.
Enter the following code into the
forms.py file of the geeks application.
Add geek app in
Now, to convert this form to a view, we need a view and a URL associated with that URL. Let`s first create a view in the
views.py of the geeks app,
Here we import this particular form from forms.py and instantiate it in the view so that it could be displayed in the template.
Now, to initiate your Django form, you need to create a home.html where you can create things as you see fit. Let`s create a form in
Finally, the URL to map to this view in urls.py
Let`s start the server and check what`s on actually happened, Run
Python manage.py runserver
geeks_field GenericIPAddressField is generated by replacing "_" with "". This is a field for entering IP addresses.
GenericIPAddressField is used to enter an IP address into the database. You can enter the user`s IP address, IPv4, etc. So far, we`ve discussed how to implement GenericIPAddressField, but how to use it in the view to execute the boolean part. To do some logic, we need to get the value entered in the field into a Python string instance. To get the GitHub code for a working GenericIPAddressField, Click views here. py,
Now let`s let`s try some other data in the field.
You can clearly see that he asks for a valid IP address. Let`s try to enter a valid IP address now.
This data can now be retrieved using the appropriate query dictionary. If the method is GET, the data will be available in request.GET, and if post, then request.POST , respectively. In the above example, we have a value in temp that we can use for any purpose. You can check that the data is being converted to a Python string instance in the geeks_field.
Main Field Arguments — they are arguments given to each field to apply some kind of constraint or to convey a particular characteristic to a particular field. For example, adding the
required = False argument to the GenericIPAddressField will allow the user to leave it blank. Each Field constructor takes at least these arguments. Some Field classes accept additional field-specific arguments, but you should always accept the following:
|required|| By default, each Field class assumes the value is required, so to make it not required you need to set |
|label||The label argument lets you specify the “ human-friendly ”label for this field. This is used when the Field is displayed in a Form.|
|label_suffix||The label_suffix argument lets you override the form`s label_suffix on a per-field basis.|
|widget||The widget argument lets you specify a Widget class to use when rendering this Field. See Widgets for more information. td>|
|help_text||The help_text argument lets you specify descriptive text for this Field. If you provide help_text, it will be displayed next to the Field when the Field is rendered by one of the convenience Form methods.|
|error_messages||The error_messages argument lets you override the default messages that the field will raise. Pass in a dictionary with keys matching the error messages you want to override.|
|validators||The validators argument lets you provide a list of validation functions for this field.|
|localize||The localize argument enables the localization of form data input, as well as the rendered output.|
|disabled||The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won`t be editable by users.tr>|
