I have tried this both ways and each time same results, duplicate
entries.
Here is the simple test:
t = Trim.find(:first, :conditions => ['id > 65000000'])
options = Option.find_all_by_trim_id(t.id)
puts options.size
v = NewVehicle.new({:trim_id => t.id})
v.option_ids = options.map {|o| o.id}
v.save
I also tried it just with v.options = options, using option_ids was
just another attempt to make this work
The size of options in this case is 47. options_vehicles which is my
join table will have 94 results exactly 2 of each one option. So if
the option_id = 6 and vehicle_id is 4 i have 6,4 in the join table
twice.
I am doing one thing a little odd, but i have no idea what's causing
this issue. My models look like this:
Option.rb
set_primary_key "option_id"
has_many :options_vehicles
has_many :vehicles, :through => :options_vehicles
I have to use option_id as the primary key and it's a string. This is
other data i'm importing and I can't change the way it's organzied.
Vehicle.rb
has_many :options_vehicles,
has_many :options, :through => :options_vehicles
My join table looks like a habtm table because it was. I have tried
this both ways activerecord continues to put in dupes.
I actually went into the code at
/data/www/production/vendor/rails/activerecord/lib/active_record/
associations.rb:1392
and put prints in there and see it showing the size of the records to
save as 47, but it's going through here twice.
I have option_id in options marked as the primary key with a unique
index in mysql.
Any help would be appreciated I feel like I'm going crazy...
