# `PhoenixKitCatalogue.Catalogue.Manufacturers`
[🔗](https://github.com/BeamLabEU/phoenix_kit_catalogue/blob/0.1.14/lib/phoenix_kit_catalogue/catalogue/manufacturers.ex#L1)

Manufacturers — company directory used as the source of items.

Hard-deletes only (manufacturers are reference data, not user content).
Status field is `"active"` / `"inactive"`; inactive manufacturers
remain in the DB but are filtered from item dropdowns.

Public surface is re-exported from `PhoenixKitCatalogue.Catalogue` via
`defdelegate`, so callers can keep using the canonical context module.

```elixir
@spec change_manufacturer(PhoenixKitCatalogue.Schemas.Manufacturer.t(), map()) ::
  Ecto.Changeset.t(PhoenixKitCatalogue.Schemas.Manufacturer.t())
```

# `create_manufacturer`

```elixir
@spec create_manufacturer(
  map(),
  keyword()
) ::
  {:ok, PhoenixKitCatalogue.Schemas.Manufacturer.t()}
  | {:error, Ecto.Changeset.t(PhoenixKitCatalogue.Schemas.Manufacturer.t())}
```
