The concept is clear enough: a Playdate has many Users, but they are indirectly related through the Invitation class. Getting the "has_many through" correct was kind of tricky, in part because I misunderstood both the "through" and the "source". I assumed they referred to tables. In reality the "through" refers to *another association on Playdate* (although in this case it has the same name as a table). The "source" refers not to a table, but to an association of the class indicated by "through".</p>jfrankFri, 09 Nov 2007 16:37:18 -0000
