API References

cms.api

Python APIs for creating CMS contents. This is done in cms.api and not on the models and managers, because the direct API via models and managers is slightly counterintuitive for developers. Also the functions defined in this module do sanity checks on arguments.

Warning

None of the functions in this module does any security or permission checks. They verify their input values to be sane wherever possible, however permission checks should be implemented manually before calling any of these functions.

Warning

Due to potential circular dependency issues, it’s recommended to import the api in the functions that uses its function.

e.g. use:

def my_function():
    from cms.api import api_function
    api_function(...)

instead of:

from cms.api import api_function
def my_function():
    api_function(...)

cms.api.``VISIBILITY_USERS

Used for the limit_menu_visibility keyword argument to create_page(). Limits menu visibility to authenticated users.

cms.api.``VISIBILITY_STAFF

Used for the limit_menu_visibility keyword argument to create_page(). Limits menu visibility to staff users.

cms.api.``create_page(title, template, language, menu_title=None, slug=None, apphook=None, apphook_namespace=None, redirect=None, meta_description=None, created_by=’python-api’, parent=None, publication_date=None, publication_end_date=None, in_navigation=False, soft_root=False, reverse_id=None, navigation_extenders=None, published=False, site=None, login_required=False, limit_visibility_in_menu=VISIBILITY_ALL, position=”last-child”)

Creates a cms.models.pagemodel.Page instance and returns it. Also creates a cms.models.titlemodel.Title instance for the specified language.

cms.api.``create_title(language, title, page, menu_title=None, slug=None, redirect=None, meta_description=None, parent=None)

Creates a cms.models.titlemodel.Title instance and returns it.

Warning

This function skips permissions checks

Example workflows

Create a page called 'My Page using the template 'my_template.html' and add a text plugin with the content 'hello world'. This is done in English:

from cms.api import create_page, add_plugin
page = create_page('My Page', 'my_template.html', 'en')
placeholder = page.placeholders.get(slot='body')
add_plugin(placeholder, 'TextPlugin', 'en', body='hello world')

cms.toolbar

All methods taking a side argument expect either cms.constants.LEFT or cms.constants.RIGHT for that argument.

Methods accepting the position argument can insert items at a specific position. This can be either None to insert at the end, an integer index at which to insert the item, a cms.toolbar.items.ItemSearchResult to insert it before that search result or a cms.toolbar.items.BaseItem instance to insert it before that item.

cms.toolbar.toolbar

class cms.toolbar.toolbar.``CMSToolbar

The toolbar class providing a Python API to manipulate the toolbar. Note that some internal attributes are not documented here.

All methods taking a position argument expect either cms.constants.LEFT or cms.constants.RIGHT for that argument.

This class inherits cms.toolbar.items.ToolbarMixin, so please check that reference as well.

• is_staff

  Whether the current user is a staff user or not.

• edit_mode

  Whether the toolbar is in edit mode.

• build_mode

  Whether the toolbar is in build mode.

• show_toolbar

  Whether the toolbar should be shown or not.

• csrf_token

• toolbar_language

  Language used by the toolbar.

• add_item(item, position=None)

  Low level API to add items.

  Adds an item, which must be an instance of cms.toolbar.items.BaseItem, to the toolbar.

  This method should only be used for custom item classes, as all builtin item classes have higher level APIs.

  Read above for information on position.

• remove_item(item)

  Removes an item from the toolbar or raises a KeyError if it’s not found.

• get_or_create_menu(key. verbose_name, side=LEFT, position=NOne)

  If a menu with key already exists, this method will return that menu. Otherwise it will create a menu for that key with the given verbose_name on side at position and return it.

• add_button(name, url, active=False, disabled=False, extra_classes=None, extra_wrapper_classes=None, side=LEFT, position=None)

  Adds a button to the toolbar. extra_wrapper_classes will be applied to the wrapping div while extra_classes are applied to the <a>.

• add_button_list(extra_classes=None, side=LEFT, position=None)

  Adds an (empty) button list to the toolbar and returns it. See cms.toolbar.items.ButtonList for further information.

cms.toolbar.items

class cms.toolbar.items.``ItemSearchResult

Used for the find APIs in ToolbarMixin. Supports addition and subtraction of numbers. Can be cast to an integer.

• item

  The item found.

• index

  The index of the item.

class cms.toolbar.items.``ToolbarMixin

Provides APIs shared between cms.toolbar.toolbar.CMSToolbar and Menu.

The active and disabled flags taken by all methods of this class specify the state of the item added.

extra_classes should be either None or a list of class names as strings.

• REFRESH_PAGE

  Constant to be used with on_close to refresh the current page when the frame is closed.

• LEFT

  Constant to be used with side.

• RIGHT

  Constant to be used with side.

• get_item_count()

  Returns the number of items in the toolbar or menu.

• add_item(item, position=None)

  Low level API to add items, adds the item to the toolbar or menu and makes it searchable. item must be an instance of BaseItem. Read above for information about the position argument.

• remove_item(item)

  Removes item from the toolbar or menu. If the item can’t be found, a KeyError is raised.

• find_items(item_type, \*attributes*)

  Returns a list of ItemSearchResult objects matching all items of item_type, which must be a subclass of BaseItem, where all attributes in attributes match.

• find_first(item_type, \*attributes*)

  Returns the first ItemSearchResult that matches the search or None. The search strategy is the same as in find_items(). Since positional insertion allows None, it’s safe to use the return value of this method as the position argument to insertion APIs.

• add_sideframe_item(name, url, active=False, disabled=False, extra_classes=None, on_close=None, side=LEFT, position=None)

  Adds an item which opens url in the side frame and returns it.

  on_close can be set to None to do nothing when the side frame closes, REFRESH_PAGE to refresh the page when it closes or a URL to open once it closes.

  on_close can be set to None to do nothing when the side modal closes, REFRESH_PAGE to refresh the page when it closes or a URL to open once it closes.

  Note: The default value for on_close is different in add_sideframe_item() then in add_modal_item()

• add_link_item(name, url, active=False, disabled=False, extra_classes=None, side=LEFT, position=None)
