I have a product class with category and a polymorphic attributes details_info, that depending on category go to one or another table to get the detail
and to display products i do
prds = Products.all
prds.each do |pr|
if pr.category == ‘pencil’
DetailsInfo.table_name = ‘pencil’
else if pr.category == ‘notebook’
DetailsInfo.table_name = ‘notebook’
(this is just kind of algo I use)
All this was working fine but with rails > 4.2 , it doesnt work anymore.
The first time pr.details_info will be called, it seems that the table name is cached somewhere, and then all other products are using the same table_name. When I check during loop, I can see that DetailsInfo.table_name is always correct, but still when pr.details_info will be called , it used the first table_name that was used. I can also see that the method table_name is called every step of the loop, and it return the good table_name, but still, the sql request search on bad table.
How can I reset that ? Ive tried a lot a thing like emptying association_cache, also different things with reflect_on_all_associations, reset_column_information, reload, …
