Hi there!
I have a schema looking something like this:
defmodule Shop.Order do
schema "orders" do
embeds_many :lines, Line
end
end
defmodule Shop.Line do
embedded_schema do
belongs_to :product, Product
end
end
Now I’m trying to preload the products in the embedded Line-schema, but I get an error-message:
query = from(o in Order, limit: 1, preload: [lines: :product])
Repo.one(query)
# => schema Shop.Order does not have association :lines
That sort-of makes sense, I suppose, but is there a way around this?
Where Next?

Migrated away from embedded-schema’s to regular association with lines-table. Would still be interested to know if it’s possible to do it with
embedded_schemathough.preciz
I just had the same problem and a search for the solution led me here.
I have wrote a quick
Enum.reduce/3implementation with caching using a map to solve it for myself.I’m also interested to ask if there is a better solution and if there isn’t one maybe extending Ecto with one would be desirable?

Afaik belongs_to is now supported in ecto, even though it’s not backed by a foreign key constraint in the db.
