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.

When i click on the onepage.html.erb. that have one button when i click on

Thanks, But here now am facing another problem
class onepages_controller
before_filter :show

def onepage

// have to access show method variables
end

protected

def show
// here  read the value from user via textfield
render 'onepages/onepage'
end

end

In my code, when i click on the onepage.html.erb, that have one textfield
and button, where i have to read one value from user. so if i given like the
above code, first check the before_filter,the show function will execute,
but the show function doesn't getting the textfield value, Page will give
error. Have any way to do that?
