undefined method error while accessing another controllers method

My product controller looks like this:

class ProductsController < InheritedResources::Base

public
    def product_params(p=params)
      p.require(:product).permit(:manufacturer, :part_no, :avatar)
    end
end

Item has one to one relationship with product. In Item's controller (activeadmin) cI am doing this:

@item.product = Product.create(ProductsController.product_params(params[:item]))

And got this error:

undefined method `product_params' for ProductsController:Class

Now please help me to figure out what am I doing wrong.

Your controller implement product_params as instance method, not like static class method.

We have two ways to fix it:

  • declare products_params as static class method.
  • call to produtcs_params to current instance.

First option:

def self.product_params(p=params)
  p.require(:product).permit(:manufacturer, :part_no, :avatar)
end

Second option:

@item.product = Product.create(product_params(params[:item]))

product_params is an instance object method, of the class ProductsController

You are calling product_params on class ProductsController, and such does not exist, product_params is not class method it is instance object method, it can only be called on instance object of ProductsController
