Layout declaration

Rails
1

Hi all.

We have been trying to do a custom layout for special user’s via
something like this:

class ProductsController < ApplicationController

def show
products_layout
@product = Product.find(params[:id])
end

private def products_layout
layout ‘special’ if @current_user.special?
layout ‘not_special’ unless @current_user.special?
end

end

We got a ‘no such method error’ on layout.

via the url below:

we know that below is the right way to do it but my question is

From a ruby perspective what is ‘layout’ if it is not a method?

class ProductsController < ApplicationController
layout :products_layout

def show
@product = Product.find(params[:id])
end

private def products_layout
@current_user.special? ? “special” : “products”
end

end

Then do it that way. :slight_smile:

Of course it’s a method. It’s a class method in the controller. So to
call it from within an instance method, you’d have to call
self.class.layout.

class ProductsController < ApplicationController
layout :products_layout

def show
@product = Product.find(params[:id])
end

private def products_layout
@current_user.special? ? “special” : “products”
end

end

Best,
