Re: Instance variable access with different methods in one controller and view
Instance variables in Rails controllers are only shared for a request -
response cycle. Ie, you cannot access variables set in the show action from
the onepage action. You will need to reinitialise them. If you want to keep
things DRY, put it in a before filter.
eg:
class onepages_controller
before_filter :filter_name
def show
render ''onepages/onepage''
end
def onepage
// have to access show method variables
end
protected
def filter_name
@name = "name1"
end
end
You will now have @name in both show and onepage.
