Question

I am new to Ruby and I have a question. I am trying to have a controller call a model class which would query a MySQL database.

What is the correct way to set this up? I am trying not to use scaffolding so that I learn how to do this by hand.

Answer 1

class MyController < ApplicationController
  def index
    @post = Post.find(params[:id])
  end
end

when calling index, you will find post in database which id is equal to id given in paramaterer (http://localhost/my_controllers/id)
