Scaffolding plugin

Plugin details

Scaffolding is a way to quickly put an Active Record class online by providing a series of standardized actions for listing, showing, creating, updating, and destroying objects of the class. These standardized actions come with both controller logic and default templates that through introspection already know which fields to display and which input types to use. Example:

The render_scaffold method will first check to see if you've made your own template (like "weblog/show.erb" for the show action) and if not, then render the generic template for that action. This gives you the possibility of using the scaffold while you're building your specific application. Start out with a totally generic setup, then replace one template and one action at a time while relying on the rest of the scaffolded templates and actions.

Documentation

Install the plugin: 
ruby script/plugin install http://dev.rubyonrails.org/svn/rails/plugins/scaffolding/
class WeblogController < ActionController::Base
  scaffold :entry
end


This tiny piece of code will add all of the following methods to the controller: 

class WeblogController < ActionController::Base
  verify :method => :post, :only => [ :destroy, :create, :update ],
         :redirect_to => { :action => :list }

  def index
    list
  end

  def list
    @entries = Entry.find(:all)
    render_scaffold "list"
  end

  def show
    @entry = Entry.find(params[:id])
    render_scaffold
  end

  def destroy
    Entry.find(params[:id]).destroy
    redirect_to :action => "list"
  end

  def new
    @entry = Entry.new
    render_scaffold
  end

  def create
    @entry = Entry.new(params[:entry])
    if @entry.save
      flash[:notice] = "Entry was successfully created"
      redirect_to :action => "list"
    else
      render_scaffold('new')
    end
  end

  def edit
    @entry = Entry.find(params[:id])
    render_scaffold
  end

  def update
    @entry = Entry.find(params[:id])
    @entry.attributes = params[:entry]

    if @entry.save
      flash[:notice] = "Entry was successfully updated"
      redirect_to :action => "show", :id => @entry
    else
      render_scaffold('edit')
    end
  end
end
