What is the complexity of active record Model.columns or Model.column_names operation on rails?
Basically I have an option of either hard coding it like that:
do_something(:column_name1) do_something(:column_name2) do_something(:column_name3)or I can do that as following:
columns = Model.columns columns.each do |c| do_something(c.name) endI want to use the second one, because I have to do that in couple of models and if I choose the second option it saves me time and lines of code. But I am thinking if I had to face any time penalty at run time or not?
