Admin Customization

Mezzanine uses the standard Django admin interface allowing you to add admin classes as you normally would with a Django project, but also provides the following enhancements to the admin interface that are configurable by the developer.

Custom Items

It is possible to inject custom navigation items into the ADMIN_MENU_ORDER setting by specifying an item using a two item sequence, the first item containing the title and second containing the named urlpattern that resolves to the url to be used.

Continuing on from the previous example, Mezzanine includes a fork of the popular django-filebrowser application which contains a named urlpattern fb_browse and is given the title Media Library to create a custom navigation item:

    ("Content", ("pages.Page", "blog.BlogPost", "blog.Comment",
        ("Media Library", "fb_browse"),)),
    ("Site", ("auth.User", "auth.Group", "sites.Site", "redirects.Redirect")),

You can also use this two-item sequence approach for regular app/model names if you’d like to give them a custom title.


When using the standard Django admin interface, the dashboard area shown when a user first logs in provides the list of available models and a list of the user’s recent actions. Mezzanine makes this dashboard configurable by the developer by providing a system for specifying Django Inclusion Tags that will be displayed in the dashboard area.

The dashboard area is broken up into three columns, the first being wide and the second and third being narrow. Mezzanine then provides the setting DASHBOARD_TAGS which is a sequence of three sequences - one for each the three columns. Each sequence contains the names of the inclusion tags in the format tag_lib.tag_name that will be rendered in each of the columns .

The list of models and recent actions normally found in the Django admin are available as inclusion tags via mezzanine_tags.app_list and mezzanine_tags.recent_actions respectively. For example, to configure the dashboard with a blog form above the model list in the first column, a list of recent comments in the second column and the recent actions list in the third column, you would define the following in your projects’s settings module:

    ("blog_tags.quick_blog", "mezzanine_tags.app_list"),

Here we can see the quick_blog inclusion tag provided by the module and the recent_comments inclusion tag provided by the mezzanine.generic.templatetags.comment_tags module.


By default, Mezzanine uses the TinyMCE editor to provide rich editing for all model fields of the type mezzanine.core.fields.RichTextField. The setting RICHTEXT_WIDGET_CLASS contains the import path to the widget class that will be used for editing each of these fields, which therefore provides the ability for implementing your own editor widget which could be a modified version of TinyMCE, a different editor or even no editor at all.


If you’d only like to customize the TinyMCE options specified in its JavaScript setup, you can do so via the TINYMCE_SETUP_JS setting which lets you specify the URL to your own TinyMCE setup JavaScript file.

The default value for the RICHTEXT_WIDGET_CLASS setting is the string "mezzanine.core.forms.TinyMceWidget". The TinyMceWidget class referenced here provides the necessary media files and HTML for implementing the TinyMCE editor, and serves as a good reference point for implementing your own widget class which would then be specified via the RICHTEXT_WIDGET_CLASS setting.

In addition to RICHTEXT_WIDGET_CLASS you may need to customize the way your content is rendered at the template level. Post processing of the content can be achieved through the RICHTEXT_FILTERS setting, which is a sequence of string, each one containing the dotted path to a Python function, that will be used as a processing pipeline for the content. Think of them like Django’s middleware or context processors.

Say, for example, you had a RICHTEXT_WIDGET_CLASS that allowed you to write your content in a popular wiki syntax such as markdown. You’d need a way to convert that wiki syntax into HTML right before the content was rendered:

# ... in myproj.filter
from markdown import markdown

def markdown_filter(content):
    Converts markdown formatted content to html
    return markdown(content)

# ... in myproj.settings

With the above, you’d now see the converted HTML content rendered to the template, rather than the raw markdown formatting.

Media Library Integration

Mezzanine’s Media Library (based on django-filebrowser) provides a jQuery UI dialog that can be used by custom widgets to allow users to select previously uploaded files.

When using a custom widget for the WYSIWYG editor via the RICHTEXT_WIDGET_CLASS setting, you can show the Media Library dialog from your custom widget, by doing the following:

  1. Load the following media resources in your widget, perhaps using a Django Media inner class:

    mezzanine/js/%s' % settings.JQUERY_FILENAME
  2. Call the JavaScript function browseMediaLibrary to show the dialog. The function is defined in filebrowser/js/filebrowser-popup.js, and takes the following two arguments:

    Callback function:

    The function that will be called after the dialog is closed. The function will be called with a single argument, which will be:

    • null: if no selection was made (e.g. dialog is closed by hitting ESC), or
    • the path of the selected file.
    Type (optional):

    Type of files that are selectable in the dialog. Defaults to image.
