Hi, I'm working with two models that have a "has_and_belongs_to_many"
relation. Both models reside on a database that it is not the default
one.
A < External
has_and_belongs_to_many: B
B < External
has_and_belongs_to_many: A
Retriving the information for A works perfectly, but when trying to
"create" an element on A:
"A.B.create(...)"
ActiveRecord tries to create it on the default database. The solution
was doing:
b = B.find(...)
A.B << b
But, looking on the sourcecode I've found on the ActiveRecord file
"has_and_belongs_to_many_association.rb [25:29]"
def has_primary_key?
return @has_primary_key unless @has_primary_key.nil?
@has_primary_key =
(ActiveRecord::Base.connection.supports_primary_key? &&
ActiveRecord::Base.connection.primary_key(@reflection.options
[:join_table]))
end
Shouln't it be something like?
def has_primary_key?
return @has_primary_key unless @has_primary_key.nil?
@has_primary_key = (@owner.connection.supports_primary_key? &&
@owner.connection.primary_key(@reflection.options
[:join_table]))
end
Thank you
