Hi all,  
I’m having some methods in application.rb. I have to use those  
methods in my model.  
How can i do that?  
Thanks in advance.

I think can do like

ins = ApplicationController.new  
ins.method\_name #method\_name is any def in pplication  
controller

```
    But why are you calling controller methods from model

I’d agree with Sijo here - if you need controller models in the model,  
something has gone wrong with your design. Either the methods are  
really model methods (maybe class methods on the model?), or you’re  
trying to do view stuff in the models. Can you post an example of  
where you’re running into this problem?

I need those methods in many places, so i wrote in application.rb. I’m  
calling those methods in another method which is in application.rb.

So move such code to lib folder and include those modules where ever you  
need using include statement
