Let’s say I have two tables, Category and Product, a Product belongs to a Category, a Category has many Products. Let’s say I inserted all categories in the database and I also insert a product record. I want to add an association between the product and the category records after both were created. How can I achieve that in Ecto?
I tried using put_assoc but it doesn’t seem to work.
I’m not even sure what is the order in which the records should be passed to put_assoc
I’ve tried both situations
changeset = product |> Ecto.Changeset.put_assoc(:category, category) changeset = category |> Ecto.Changeset.put_assoc(:products, product)
In both cases I get
** (MatchError) no match of right hand side value:
In the first case I also get the Product record struct being returned, In the second case I get a Category record back
