Python wagtail Snippets



 In the previous few article we have explored page model. Now we will learn about Snippets in this article.     

                           Snippets

Snippets are pieces of content which do not necessitate a full webpage to render. They could be used for making secondary content, such as headers, footers, and sidebars, editable in the Wagtail admin. 

Snippets are Django models which do not inherit the Page class and are thus not organized into the Wagtail tree. However, they can still be made editable by assigning panels and identifying the model as a snippet with the register_snippetclass decorator.


                                Example snippet model

from django.db import models

from wagtail.admin.edit_handlers import FieldPanel
from wagtail.snippets.models import register_snippet

...
@register_snippet
class Advert(models.Model):
url = models.URLField(null=True, blank=True)
text = models.CharField(max_length=255)

panels = [
FieldPanel('url'),
FieldPanel('text'),
]

def __str__(self):
return self.text

Snippets do not use multiple tabs of fields, nor do they provide the "save as draft" or "submit for moderation"features.

@register_snippet tells Wagtail to treat the model as a snippet. The panels list defines the fields to show on the snippet editing page.

It's also important to provide a string representation of the class through def __str__(self):so that the snippet objects make sense when listed in the Wagtail admin
