CMSPluginBase Attributes and Methods Reference

These are a list of attributes and methods that can (or should) be overridden on your Plugin definition.

Attributes

admin_preview

Default: False

Should the plugin be previewed in admin when you click on the plugin or save it?

allow_children

Default: False

Can this plugin have child plugins? Or can other plugins be placed inside this plugin? If set to True you are responsible to render the children in your plugin template.

Please use something like this or something similar:

{% load cms_tags %}
<div class="myplugin">
    {{ instance.my_content }}
    {% for plugin in instance.child_plugin_instances %}
        {% render_plugin plugin %}
    {% endfor %}
</div>

Be sure to access instance.child_plugin_instances to get all children. They are pre-filled and ready to use. To finally render your child plugins use the {% render_plugin %} templatetag.

cache

Default: CMS_PLUGIN_CACHE

Is this plugin cacheable? If your plugin displays content based on the user or request or other dynamic properties set this to False.

Warning

If you disable a plugin cache be sure to restart the server and clear the cache afterwards.

change_form_template

Default: admin/cms/page/plugin_change_form.html

The template used to render the form when you edit the plugin.

Example:

class MyPlugin(CMSPluginBase):
    model = MyModel
    name = _("My Plugin")
    render_template = "cms/plugins/my_plugin.html"
    change_form_template = "admin/cms/page/plugin_change_form.html"

child_classes

Default: None

A List of Plugin Class Names. If this is set, only plugins listed here can be added to this plugin.

See also: parent_classes

disable_child_plugins

Default: False

Disables dragging of child plugins in structure mode.

frontend_edit_template

Default: cms/toolbar/placeholder_wrapper.html

The template used for wrapping the plugin in frontend editing.

See also: change_form_template

model

Default: CMSPlugin

If the plugin requires per-instance settings, then this setting must be set to a model that inherits from CMSPlugin.

See also: Storing configuration

page_only

Default: False

Can this plugin only be attached to a placeholder that is attached to a page? Set this to True if you always need a page for this plugin.

See also: child_classes, parent_classes, require_parent,

parent_classes

Default: None

A list of Plugin Class Names. If this is set, this plugin may only be added to plugins listed here.

See also: child_classes, require_parent

render_plugin

Default: True

Should the plugin be rendered at all, or doesn’t it have any output? If render_plugin is True, then you must also define render_template()

See also: render_template, get_render_template

render_template

Default: None

The path to the template used to render the template. If render_plugin is True either this or get_render_template must be defined;

See also: render_plugin , get_render_template

require_parent

Default: False

Is it required that this plugin is a child of another plugin? Or can it be added to any placeholder, even one attached to a page.

See also: child_classes, parent_classes

text_enabled

Default: False

Can the plugin be inserted inside the text plugin? If this is True then icon_src() must be overridden.

See also: icon_src, icon_alt

Methods

render

The render() method takes three arguments:

  • context: The context with which the page is rendered.
  • instance: The instance of your plugin that is rendered.
  • placeholder: The name of the placeholder that is rendered.

This method must return a dictionary or an instance of django.template.Context, which will be used as context to render the plugin template.

New in version 2.4.

By default this method will add instance and placeholder to the context, which means for simple plugins, there is no need to overwrite this method.

If you overwrite this method it’s recommended to always populate the context with default values by calling the render method of the super class:

def render(self, context, instance, placeholder):
    context = super(MyPlugin, self).render(context, instance, placeholder)
    ...
    return context

get_render_template

If you need to determine the plugin render model at render time you can implement get_render_template() method on the plugin class; this method taks the same arguments as render. The method must return a valid template file path.

Example:

def get_render_template(self, context, instance, placeholder):
    if instance.attr = 'one':
        return 'template1.html'
    else:
        return 'template2.html'

See also: render_plugin , render_template

icon_src

By default, this returns an empty string, which, if left unoverridden would result in no icon rendered at all, which, in turn, would render the plugin uneditable by the operator inside a parent text plugin.

Therefore, this should be overridden when the plugin has text_enabled set to True to return the path to an icon to display in the text of the text plugin.

icon_src takes 1 argument:

  • instance: The instance of the plugin model

Example:

def icon_src(self, instance):
    return settings.STATIC_URL + "cms/img/icons/plugins/link.png"

See also: text_enabled, icon_alt

icon_alt

Although it is optional, authors of “text enabled” plugins should consider overriding this function as well.

This function accepts the instance as a parameter and returns a string to be used as the alt text for the plugin’s icon which will appear as a tooltip in most browsers. This is useful, because if the same plugin is used multiple times within the same text plugin, they will typically all render with the same icon rendering them visually identical to one another. This alt text and related tooltip will help the operator distinguish one from the others.

By default icon_alt() will return a string of the form: “[plugin type] - [instance]”, but can be modified to return anything you like.

icon_alt() takes 1 argument:

  • instance: The instance of the plugin model

The default implementation is as follows:

def icon_alt(self, instance):
    return "%s - %s" % (force_text(self.name), force_text(instance))

See also: text_enabled, icon_src

text_editor_button_icon

When text_enabled is True, this plugin can be added in a text editor and there might be an icon button for that purpose. This method allows to override this icon.

By default, it returns None and each text editor plugin may have its own fallback icon.

text_editor_button_icon() takes 2 arguments:

  • editor_name: The plugin name of the text editor
  • icon_context: A dictionary containing information about the needed icon like width, height, theme, etc

Usually this method should return the icon url. But, it may depends on the text editor because what is needed may differ. Please consult the documentation of your text editor plugin.

This requires support from the text plugin; support for this is currently planned for djangocms-text-ckeditor 2.5.0.

get_extra_placeholder_menu_items

get_extra_placeholder_menu_items(self, request, placeholder)

Extends the context menu for all placeholders. To add one or more custom context menu items that are displayed in the context menu for all placeholders when in structure mode, override this method in a related plugin to return a list of cms.plugin_base.PluginMenuItem instances.

get_extra_global_plugin_menu_items

get_extra_global_plugin_menu_items(self, request, plugin)

Extends the context menu for all plugins. To add one or more custom context menu items that are displayed in the context menu for all plugins when in structure mode, override this method in a related plugin to return a list of cms.plugin_base.PluginMenuItem instances.

get_extra_local_plugin_menu_items

get_extra_local_plugin_menu_items(self, request, plugin)

Extends the context menu for a specific plugin. To add one or more custom context menu items that are displayed in the context menu for a given plugin when in structure mode, override this method in the plugin to return a list of cms.plugin_base.PluginMenuItem instances.

set_translatable_content takes 1 argument:

  • fields: A dictionary containing the field names and translated content for each.

Example:

from djangocms_text_ckeditor.models import Text

plugin = Text.objects.get(pk=1).get_plugin_instance()[0]
