I'm thinking that the following code is a step in the right
direction...
------------------------------------------------------------
def secondary_tables
secondary_tables_1 + secondary_tables_2
end
--------------------------------------------------------------
....but it ruins the association links and instead prints:
---------------------------------------------------------------
#<SecondaryTable:0x2a9942de98>#<SecondaryTable:0x2a9942bdc8>
----------------------------------------------------------------
Even if there is a more elegant solution than this method of just
concatenating the two separate has_many association variables
together, it'd be nice to know how to turn these codes back into
links.
Ideas?
