Hello
I have two schemas, and I am trying to create a relation has_many
defmodule Example.Accounts.User do
use Ecto.Schema
import Ecto.Changeset
alias Example.Accounts.User
schema "users" do
field :identification, :integer
field :name, :string
has_many :properties, Example.Properties.Property
timestamps()
end
@doc false
def changeset(%User{} = user, attrs) do
user
|> cast(attrs, [:identification, :name])
|> validate_required([:identification, :name])
end
end
And
defmodule Example.Properties.Property do
use Ecto.Schema
import Ecto.Changeset
alias Example.Properties.Property
schema "properties" do
field :n_property, :integer
belongs_to :user, Example.Accounts.User
timestamps()
end
@doc false
def changeset(%Property{} = property, attrs) do
property
|> cast(attrs, [:n_property])
|> validate_required([:n_property])
end
end
After running ecto.create and ecto.migrate the result on my PostgresDB is the following
CREATE TABLE public.properties
(
id bigint NOT NULL DEFAULT nextval('properties_id_seq'::regclass),
n_property integer,
inserted_at timestamp without time zone NOT NULL,
updated_at timestamp without time zone NOT NULL,
CONSTRAINT properties_pkey PRIMARY KEY (id)
)
WITH (
OIDS = FALSE
)
TABLESPACE pg_default;
ALTER TABLE public.properties
OWNER to postgres;
And I don’t understand, Why doesn’t it create a foreign_key?
