Ah. I found my error!
MyApp::Product
relationships => [
colors => {
type => 'many to many',
map_class => 'MyApp::Product2Color',
map_from => 'product_id',
map_to => 'color_id',
},
MyApp::Product2Color
columns => [
product_id => { type => 'bigint',
not_null => 1 },
color_id => { type => 'bigint',
not_null => 1 },
foreign_keys => [
product=> {
class => 'MyApp::Product',
key_columns => { product_id => 'id' },
},
For some stupid reason, I was naming FKeys using the same way i name
relationships -- i probably copy/pasted. changing the p2c fkey to
'product_id' fixed that immediately.
