Hash Routing - raise event in template form from route form

[yahiakala]

I just started converting an app to use hash routing. I have a situation like this:

• One template form with all possible links the user would need
• Links on that template form that are only visible if the user has certain privileges (stored in user row)
• The need to refresh the visibility of those links triggered from events in the route forms.
• Essentially, I need to trigger an event in the template form from a route form.

From the examples I have seen, people tend to have multiple template forms that are used depending on the user privileges. So they avoid the issue I'm having by creating multiple template forms and not needing to trigger events in a template form from a route form.

Here's what I did before routing:

 def load_component(self, cmpt):
     self.cmpt = cmpt
     self.content_panel.clear()
     self.content_panel.add_component(cmpt)
     cmpt.add_event_handler('x-refresh', self.refresh_links)

How would I add this event handler in a hash routing setup? Are the template forms and route forms even linked this way behind the scenes?

Figured it out - I add the refresh event in the on_navigation and on_form_load methods in the template form. I also made sure to use the load_from_cache=False option when using routing.set_url_hash() to trigger these.

Bumping this to ask the question more generally - is it possible to raise an event in a template form from the route form?

Might feel a bit hacky. But the template form is the form you would get from calling get_open_form() and you can all that from anywhere in your app. Just make sure it happens after the show event or from user actions.
