hi all

I developed user management with roles and rights, what i need now is to  
build user management interface, to give roles and rights to user.

Is it possible to call controller and get all methods in a controller?  
is it possible to get all controller names ?

i think something like class.method\_names…

anybody?

thanks

serz

Hi

Can you use Module#instance\_methods ?  
For example admin\_controller.instance\_methods

Module#instance\_methods, return all methods in a controller, but i only  
need my methods in a controller not system methods.  
Is it possible to get only def`s in a controller in some way?

What i was thinking is to open file then scan thru and pickup all  
methods.

but this is not nice.

Any1 have an Idea?

thanks

serz

See ActionController::Base.action\_methods and  
ActionController::Base#action\_methods

thanks all, controller.action\_methods works well.

I need this cause i am developing user management system, with roles and  
rights, so i need to call all action\_methods in a controller, so i could  
give rights to roles and users.

thanks again

Maybe give you another solution if you tell us why you need to get  
output all the methods in the controller?

I don’t know what you are trying to do exactly with the action\_methods,  
did you try to look at the before\_filter? you can use it in your  
controller, and give rights to certain methods for different user roles  
🙂

before\_filter :is\_admin, :only =\> %w{method methodto}
