Apologies if this has been asked before - my googling has failed me.
I currently have three tables in my DB: Orders, Items, and OrderItems.
Orders and Items have a many to many relationship, joined through OrderItems. I’m having trouble inserting
Orders and OrderItems at the same time. I’ve tried using cast_assoc
and put_assoc
but these haven’t worked.
schema "orders" do
...
has_many :order_items, OrderItems
has_many :items, through: [:order_items, :item]
...
timestamps()
end
schema "order_items" do
belongs_to :order, Order, primary_key: true
belongs_to :item, Item, primary_key: true
field :size, :string
field :params, :map
timestamps()
end
The table “items” does not contain any has_many
rows as I do not need to access the relationship from this way.
How would be best to create and insert records for both orders
and order_items
at the same time?
