ExTenant v0.2.2

ExTenant.Changeset (ExTenant v0.2.2) View Source

The function 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, [:name, :body])
  end
end
