RE: [Rails] Re: dependent drop downs

Make sure you're filling @wages in the controller. Also, look into "collection_select", similar to the following, to replace your code in the view

<%= collection_select :pay, :wage_id, @wages, :id, :wage %>


It looks like Gaurav's code has a join on the tables.
i.e. <select name="infotantra[category_id]">
Probably not necessary, if I grab the id chosen and stick it into an
instance variable.Then do and if / else.
