Hi, I'm new in ruby and i need do the next:
I want get a combobox from an array (@array) and save that value in a table called "form", into a field called "combo", i want save the value, not an id someone could tell me what i have to write? Thanks
To get what you want you need two parts...
First you need an array of the objects in question and then you need a field on a form that uses that array.
To create the array you could do something like:
def create_chapter_list chapters = Chapter.find(:all) chapter_list = Array.new chapters.each do |chapter| #Chapter ID must be place in the array as an integer - that is how it is stored in the DB chapter_list << [chapter.school_and_name, chapter.id] end return chapter_list.sort! end
Note that the array has two values per element so its an array in an array. What you put in the first slot is what you would see in the list and the second is what you would have submitted in a form.
Then in the form you would reference that array:
<%= f.select :chapter_id, @chapter_list, :prompt => 'Select a Chapter' %>
In this example I am using a select object but the idea is the same for all the list selection types in a form. There are details on the form options in the RoR documentation ... for example:
