Has and Belongs to Many question

[Mayank Sharma]

Hi,

I am trying to store a list of interconnected graph nodes using active records in rails. For this I am using Has and Belongs to Many association for my node. The problem is that in the join table I wish to store the weight of the edge between the two nodes as well. That in itself is not an issue as I can add an extra column in the join table. But how do I access (read/write) this column from my nodes model?

Any good ideas?

Hi Mayank,

In general, if you need to put attributes on the join table, i.e. want to make join table a model, you should use has_many :through associations in place of HABTM.

HTH.

Amit.
