ExTenant.Changeset (ExTenant v0.1.5) View Source

##cast_tenanted(changset, attrs, allowed)

injects the tenant_id key/atom into the allowed fields
retrieves the tenant_id value from the process dictionary
injects the %{"tenant_id" => tenant_id} into the attrs map
and then calls the standard Ecto.Changeset.cast function

##An exception will be raised in the following two situations

if the Repo was not set in the Config.exs file
if the tenant_id in the process dictionary is nil

##Here is an example

defmodule Post do
  use ExTenant.Schema
  use ExTenant.Changeset

  ...

  defp changeset(attrs) do
    %__MODULE__{}
    |> cast_tenanted(params, [:field1, :field1])
  end
end
