Is it a class method or an instance method? Meaning do you call it from
an instance of that model:

@model.some_method

Or do you call it on the model itself:

Model.some_method?

If it’s an instance method, you just need to have an instance in the
controller action:

def index
@instance = Model.find(params[:id])
@instance.some_method
end

If you’re dealing with a class method you would do this:

def index
Model.some_method
end

Note: swap out “Model” for the actual name of the model (User, BlogPost,
etc.)

Hope this helps. Post if you have any other questions.

Model.method

Controllers and models are not related so you can do this from any
controller

If you make sure that method is defined with “self”, you can call it
from the controllers. For example,

#A Method that can be called from a controller.
def self.my_hello_string
“Hello!”
end

Now you can say Model.my_hello_string from a controller, and it will
return what you expect, instead of complaining that the method isn’t
defined.
