Project description
wagtail_fedit
Wagtail FEdit is a library to allow your Wagtail pages and content-blocks to be edited on the frontend.
Getting Started
-
Add 'wagtail_fedit' to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [ ..., 'wagtail_fedit', ] -
Run
py ./manage.py collectstatic.
Getting Editing!
-
Make sure the models you wish to edit inherit from PreviewableMixin.
This is a requirement.
-
Define a template for your model.
Example:
{% load fedit static wagtailuserbar %} {# Load the required template tag libraries #} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> <link rel="stylesheet" href="{% static 'wagtail_fedit/css/frontend.css' %}"> </head> <body> {# Pass in the field_name and the model instance on which that field resides. #} <h1>{% fedit_field "title" self %}</h1> {# Pass in the field_name and the model instance on which that field resides. #} <main class="my-streamfield-content"> {% fedit_field "content" self %} </main> {% wagtailuserbar %} <script src="{% static 'wagtail_fedit/js/frontend.js' %}"></script> </body> </html> -
If your needs some special form of rendering; we allow your model to define a custom render method. The format of the method name should be
render_fedit_{fieldname}. Say we want all sub-blocks of our streamfield to automatically be made editable. This wouldn't be possible in the above configuration. To fix this; we should first create a custom template to render our content.Example:
{# myapp/render_my_field.html #} {% load fedit %} {% for block in self.content %} {# Sub-Blocks wrapped by fedit_block do not require the field_name or model argument. #} {# This is taken from the parent (also wrapped by `fedit_block`); the model and field name are shared through context. #} {% fedit_block block=block block_id=block.id field_name="content" model=self %} {% endfor %}from django.template.loader import render_to_string ... class MyPage(...): # Can be any type of model. content = StreamField(...) def render_fedit_content(self, request): return render_to_string("myapp/render_my_field.html", self.get_context(request))
Your content will then automatically be rendered with that method when need be by using
{% fedit_field "content" self %} -
**But wait?! I go to my template and I do not see a way to edit!**That is true! We try to protect any styling on your actual page; we do not want to interfere.Instead; we serve the editing interface on a different URL, accessible by clicking
Frontend Editingin the Wagtail userbar. Keep an eye on that userbar! It is also used for publishing if your model inherits fromDraftStateMixin.
Permissions
Note: This is not required for pages.
The Page model already provides this interface.
We have the following basic permission requirements:
- You must have
wagtailadmin.access_adminto edit a block/field. - You must have the appropriate
app_label.change_*permission for the model.
This however only applies to editing.
We use separate permissions for publishing and submitting workflows, etc.
Models which you want to allow the publish view for should also implement a PermissionTester- like object.
Example of how you should implement the Tester object and all required permissions. (More details in models.py)
class MyModel(...):
def permissions_for_user(self, user):
return MyModelPermissionTester(self, user)
class MyModelPermissionTester(...):
def can_unpublish(self):
""" Can the user unpublish this object? (Required for un-publishing"""
def can_publish(self):
""" Can the user publish this object? (Required for publishing)"""
def can_submit_for_moderation(self):
""" Can the user submit this object for moderation? (Optional) """
Revisions
Revision support is included out of the box.
If your model inherits from a RevisionMixin, we will automatically create drafts for you.
These will not be published (If the model inherits from DraftStateMixin) until you choose to do so.
Workflows
We include a WorkFlow to submit this object for moderation.
More workflow support will be included in the future.
Logs
Logs are also included out of the box. We will automatically update your model's history; including possible revisions. This will allow you to backtrack each change made on the frontend. This however does mean that a possibly large amount of data will be stored in your database.
Caveats
Wagtail does not always make it's id attribute available.
This is only available to instances of StreamChild and ListChild.
Consider the following regular wagtail list loop where items is a ListBlock.
{% for item in self.items %}
{% include_block item %} {# No access to ID! Cannot edit! #}
{% endfor %}
To make this an editable block instead; we would slightly change the loop to make the block's id available.
This is done by accessing the bound_blocks of that ListBlock (StreamBlock does this automatically for the toplevel block!)
Our new loop would then be:
{% for item in self.items.bound_blocks %}
{# Field name and model are the same arguments as in the first example! #}
{% fedit_block block=item block_id=item.id field_name="content" model=my_model_instance_var %}
{% endfor %}
Note: If the parent block is wrapped with fedit_block or fedit_field the field_name and model argument can be omitted.
The parent- blocktag will share these variables through context.
This makes it possibly to easily use editable sub-blocks across multiple different model types.
If your model ISN'T capable of editing; or these variables aren't shared - your block will be rendered as normal.
