can't import the seed.rb file : HABTM issues

[svenkirsten]

After I dumped the rails database to the seed.rb file, when I want to import the data with the command rails db:seed I get this error:

rails aborted! NameError: private constant # <Class:0x007f850e9f22a8>::HABTM_UStations referenced /Users/sven/CARGO/rails_5.1/cargo_beta/db/seeds.rb:1:in '<top (required)>' bin/rails:4:in 'require' bin/rails:4:in '<main>' Tasks: TOP => db:seed

The seed.rb file begins with these entries:

Dealer::HABTM_UStations.create!([ {ustation_id: 7, dealer_id: 2} ])

There is an issue to create the HAS_AND_BELONGS_TO_MANY records. I'm not really sure if seed_dump supports HABTM records.

I had a same issue.

yeah, seed_dump does not support HAS_AND_BELONGS_TO_MANY records :(
This is also non-trivial task to fix so maybe it should be in README

I just ran into this. I guess I just have to do a db dump / restore huh?
