I am new to ruby on rails and doing a simple application as I am
studying ruby on rails.
I have a m:n relationship between people and languages ...
a person can know many langs and a lang can be known by many people ...
I want to give a GUI in which there are 2 lists of languages for a
person to edit
1 with the languages he knows
2 other languages ..
I want to allow him to add & remove languages ie shift from one list to
the other list
Eg: if person1 has english and french in the database , the lists would
List1 : List2
etc etc etc...
and he can double click or do something to select a lang in list2 and
add it to list1 and vice versa...
I thought it would be a good excerise to learn ruby but I am struck ..
I wanted to know if there is any helper class available for this kinda
Can someone suggest me as to how I can do this efficiently in ruby..
[ I currently have a string which has all languages seperated by comma
and the user can modify the string.. I parse the string @ the
controller and store it into the database.. ]
