has_and_belongs_to_many support?

[rschmitty]

Is there a way to get the records of the join tables from a has_and_belongs_to_many association?

For example, I'd like to get the assemblies_parts dumped in addition to assemblies and parts in the rails example: http://guides.rubyonrails.org/association_basics.html#the-has_and_belongs_to_many-association

is this issue addressed? . Is there any way to get dump of join tables?

Not yet. I haven't had the need/time to add support for HABTM, though I of course would be happy to merge any pull requests that provide support :)

I'm leaving this issue open as I would like to have support for HABTM at some point.

In Rails 4.1, HABTM is now implemented with has_many :through so this now pretty much works. The only problem is that you get a psuedo-model from both sides of the relationship, so I threw this in a rake task:

    # Dedupe models on table name so HABTM tables don't get dumped twice.
    Rails.application.eager_load!
    ENV['MODELS'] =
      ActiveRecord::Base.descendants.
        uniq {|c| c.table_name}.
        map(&:to_s).
        join(',')
    Rake::Task['db:seed:dump'].execute

Also see pull request #101. This is essentially the same as mschulkind's solution, but applied automatically, and only to auto-generated HABTM_* models. Is there any case in which you would not want this behavior?

This would be a cool feature!
