Class: ActiveRecord::Associations::HasManyThroughAssociation

There's no documentation for this item.

Public Methods
<<	Adds records to the association. The source record and its associates must have ids in order to create records associating them, so this will raise ActiveRecord::HasManyThroughCantAssociateNewRecords if either is a new record. Calls create! so you can rescue errors.
build
count
create!
delete	Removes `records` from this association. Does not destroy `records`.
find
method	Alias for #<<
new
new	Alias for #build
reset
size	Returns the size of the collection by executing a SELECT COUNT(*) query if the collection hasn’t been loaded and calling collection.size if it has. If it’s more likely than not that the collection does have a size larger than zero and you need to fetch that collection afterwards, it’ll take one less SELECT query if you use length.
sum	Calculate sum using SQL, not Enumerable
