how can i insert data to the database from any controller
Assuming you want to add a user from an arbitrary controller… You
would instantiate the new user in an action (‘new_user’) and save it
to the database (and raise validation errors) from a create action
(here called ‘create_user’)
class ArbitraryController < ActionController::Base
def index
@users = User.find(:all)
end
def new_user
@user = User.new
end
def create_user
@user = User.new(params[:user])
@user.save
redirect_to :action => ‘index’
end
end
You would have to define the routes in your routes.rb file like:
map.connect ‘/user/new’, :controller => ‘arbitrary’, :action =>
‘new_user’
