Hi! I have 2 relations: - recipes-categories (M:N) - recipes-flags (M:N)
I'd like to get something like:
SELECT recipes.title FROM recipes
JOIN _recipes_ctgs_recipes
ON _recipes_ctgs_recipes.id_recipe = recipes.id
JOIN recipes_ctgs
ON _recipes_ctgs_recipes.id_recipes_ctg=recipes_ctgs.id
JOIN _recipes_flgs_recipes
ON _recipes_flgs_recipes.id_recipe = recipes.id
JOIN recipes_flgs
ON _recipes_flgs_recipes.id_recipes_flg=recipes_flgs.id
WHERE recipes_ctgs.title='cat1' AND recipes_flgs.title='flag1'
when I run
sess.query(Recipe).join("ctgs").join("flgs").select(...)
it fails with
sqlalchemy.exceptions.SQLError: (ProgrammingError) table name
"_recipes_ctgs_recipes" specified more than once
where "_recipes_ctgs_recipes" is a secondary table. Full example attached.
