Dependencies problem

hi,
i am new to ruby on rails,i want to remove a field from the edit
screen,how to know whether removing that field will effect the other
screens.
i want to remove the below code from my controller
config.columns[:status].form_ui = :radio
config.columns[:status].options = {}
config.columns[:status].options[:values] = [[‘Active’, ‘A’],
[“Inactive”, ‘I’]]

thanks in advance
