Wagtail Dynamic Dropdown

A Django application which allow to use dynamically defined choices that will be updated every time the user opens edit/create page. Moreover, the choices are not migrated to the database.

Install

::

pip install wagtail-dynamic-dropdown

Then add wagtail_dynamic_dropdown to your installed apps:

::

INSTALLED_APPS = [ ... 'wagtail_dynamic_dropdown' ]

Usage

###1. Define function that will return choices

.. code:: python

def dynamic_choices(): """ Choices creation logic """ return choices

This function should return iterable which contains list of touples. Example of valid choices:

.. code:: python

choices = ( ('choice_1','label_1'), ('choice_2','label_2') )

###2. Use your function with DynamicDropdownPanel

In your model create CharField field. Then pass its name and path to choice function as arguments in DynamicDropdownPanel

.. code:: python

from wagtail_dynamic_dropdown.edit_handlers import DynamicDropdownPanel

class MyModel(): ... my_dynamic_choices = models.CharField(max_length=255, blank=True,null=True)

   content_panels = [
       DynamicDropdownPanel("my_dynamic_choices", "app_name.folder_name.file_name.function_name")
       ]

Or, instead of defining a function path, you can import it and pass it as an argument

.. code:: python

from wagtail_dynamic_dropdown.edit_handlers import DynamicDropdownPanel from app_name.folder_name.file_name import function_name

class MyModel(): ... my_dynamic_choices = models.CharField(max_length=255, blank=True,null=True)

   content_panels = [
       DynamicDropdownPanel("my_dynamic_choices", function_name)
       ]
