Bug: an actions atribute in Action function has no effect

[yak1ex]

As similar as pipe funciton has pipes attribute, action functions can have an actions attribute.
At least, there are handling codes (code fragment 1), but it cannott be reached.

An actions attribute in an action function module is checked at code fragment 1.
As we can see from code fragment 3, get_function_module_by_id() only sets its local variable function_module and returns nothing.
Therefore, the function_module at code fragment 2 is constantly None then hasattr(module, "actions") at code fragment 1 becomes false.

Without modification, only 1 action button was shown even though actions has 2 entries.
After the proposed modification, 2 action buttons are shown as expected.

Code fragment

1. actions attribute is checked here

open-webui/backend/open_webui/utils/models.py

Line 170 in b03fc97

# Process action_ids to get the actions

    # Process action_ids to get the actions
    def get_action_items_from_module(function, module):
        actions = []
        if hasattr(module, "actions"):
            actions = module.actions
            return [
                {

2. get_action_items_from_module() is called here

open-webui/backend/open_webui/utils/models.py

Line 216 in b03fc97

function_module = get_function_module_by_id(action_id)

            function_module = get_function_module_by_id(action_id)
            model["actions"].extend(
                get_action_items_from_module(action_function, function_module)
            )

3. get_function_module_by_id()

open-webui/backend/open_webui/utils/models.py

Line 196 in b03fc97

def get_function_module_by_id(function_id):

    def get_function_module_by_id(function_id):
        if function_id in request.app.state.FUNCTIONS:
            function_module = request.app.state.FUNCTIONS[function_id]
        else:
            function_module, _, _ = load_function_module_by_id(function_id)
            request.app.state.FUNCTIONS[function_id] = function_module
