Because each plugin added the additional tables used in the query select
list:
def get_content_article_by_slug(environ, content_type, query):
tables = [schema.content_article, schema.categories]
query = query.column(schema.content_article)
query = query.column(schema.categories)
return query, tables
I have refactored the code and now it works without problems.
I use both the select method on the Join instance (when the plugins does
not need to modify the query object), and the util.folded_equivalents
function by hand.
I have read the ticket 1131, and it seems that the folded_equivalents
function was used, in the ORM, for exactly the same reason as I'm doing now.
So, it seems that nobody is doing this without using the ORM.
Is it a problem to revoke the deprecation on the folded_equivalents?
I don't think I can go without it.
Thanks Manlio
