hi all, since i have started to learn the rails just now, i got shocked after seeing the file extentions from .rhtml to .html.erb… when i started to learn the ROR, i used rails 1.2.6 then i thought of installing the latest version of rails. then i gave it… gem install rails --include-dependencies … in console it installed rails 2.0.2 then i created a new project with model and controller… in the controller i gave the code as scaffold :recipe then it says undefined variable ‘scaffold’ like this it gives for some keywords how can i solve this problem… is there any specific tutorial available for rails 2.0.2 in online. plz. guide me to know that… another one questions… is there any posibilities to install 1.2.6 after uninstalling rails 2.0.2 thanks in advance. ---

If you want scaffold either install 1.2.6 as explained above (the last version of rails to include the scaffold command) OR Install the Scaffold plugin for Rails 2.0 which brings back the command. [http://svn.rubyonrails.org/rails/plugins/scaffolding/](http://svn.rubyonrails.org/rails/plugins/scaffolding/) You can install plugins rather easily. Go to the rails source code folder in the terminal and type ruby script/plugin install [http://svn.rubyonrails.org/rails/plugins/scaffolding/](http://svn.rubyonrails.org/rails/plugins/scaffolding/) and that should then install the scaffolding plugin which will give you back the command. ---
