Hey,
is there a comfortable way to seed the database that has a table which associates a table with a unique constraint. I want to create or use my assocs on-the-fly
%{length: 11,
width: 20,
bg_color: %{color: "red"},
border_color: %{color: "red"}
}
When I cast_assoc
my association bg_color
is inserted into the Color
table, but when casting the border_color
, I get a unique-constraint error.
Sure, I could create all colors beforehand and then just put_assoc
them, but that’s not so convenient to handle with Ids.
I wrote a function get_or_insert()
which I use like that:
%{length: 11,
width: 20,
bg_color: Color.get_or_insert(color: "red"),
border_color: get_or_insert(color: "red")
}
But I ask myself if there’s a builtin Ecto way to do this?
