ja_resource v0.3.1 JaResource.Delete behaviour

Defines a behaviour for deleting a resource and the function to execute it.

It relies on (and uses):

JaResource.Repo
JaResource.Record

When used JaResource.Delete defines the delete/2 action suitable for handling json-api requests.

To customize the behaviour of the update action the following callbacks can be implemented:

handle_delete/2
JaResource.Record.record/2
JaResource.Repo.repo/0

Specs

handle_delete(Plug.Conn.t, JaResource.record) ::
  Plug.Conn.t |
  JaResource.record |
  nil

Returns an unpersisted changeset or persisted model representing the newly updated model.

Receives the conn and the record as found by record/2.

Default implementation returns the results of calling Repo.delete(record).

Example custom implementation:

def handle_delete(conn, record) do
  case conn.assigns[:user] do
    %{is_admin: true} -> super(conn, record)
    _                 -> send_resp(conn, 401, "nope")
  end
end
