text_field for join table metadata with HMT


I am having trouble making a text_field that changes the attribute of a column in a join table (made using has_many :through).

Here a summary of my code:

#Table create_table thingstuff: thing_id, stuff_id, helpme

#Relationship thing has_many stuffs :through thingstuff

#Code for thing in @stuff.find(:all) text_field "thing[thingstuff]", "helpme", :size => 2

So, of course, that doesn't work. What I want to do is change the "helpme" attribute that is related to the "thing" and "stuff". There is only 1 row in "thingstuff" that has a specific "thing" and "stuff".

Would someone shed light on this ordeal? I might be using the wrong approach.

Create a boolean attribute that connects to a checkbox. Without any
specific info about your app it's difficult to give sugestions
