API References¶
cms.api¶
Python APIs for creating CMS content. 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(...)
