ActiveAdmin

An administration framework for Ruby on Rails

The Problem 

class PostsController < ApplicationController
  def update
    @post = Post.find(params[:id])
    @post.update_attributes(params[:post])
  end
end

class PagesController < ApplicationController
  def update
    @page = Page.find(params[:id])
    @page.update_attributes(params[:page])
  end
end

The Problem 

  <%= form_for(@post) do |f| %>
    <%= f.text_field :title %>
    <%= f.text_area :body %>

    <%= f.submit %>
  <% end %>

  <%= form_for(@page) do |f| %>
    <%= f.text_field :title %>
    <%= f.text_area :body %>

    <%= f.submit %>
  <% end %>

The Solution 

ActiveAdmin.register Post do
end

ActiveAdmin.register Page do
end
