I have a symfony application with two different applications (frontend, backend) but there is one action in common. Now I have duplicated its code in both apps but I don't like that at all.
Is there a way to reuse an action in multiple symfony applications?
The easiest way would be to make an actions base class in lib with the shared methods/actions. Then the modules that need to use this functionality can just extend that base class instead of sfActions.
You could also probably just use an event listener on method_not_found of sfComponent. But that may not work as expected if the method is an actual action (and it would also be available in all modules and all components without some special detection logic).
The most complicated way would be to make a Plugin. Of course that would require making the logic that works with any models dynamic so it can be configured or isolating the relevant parts of the schema to the plugin's schema.
