# `MishkaGervaz.Form.Entities.DataLoader`
[🔗](https://github.com/mishka-group/mishka_gervaz/blob/v0.0.1-alpha.3/lib/mishka_gervaz/form/entities/data_loader.ex#L1)

Data-loader module overrides — replace the default record / tenant /
relation / hook loaders with your own implementations.

Two calling styles. Pass a module positionally to override the entire
data loader, or use the block form to swap individual sub-builders
while keeping the defaults for the rest:

    # Whole-module override
    data_loader MyApp.Form.CustomDataLoader

    # Per-sub-builder overrides
    data_loader do
      record MyApp.Form.DataLoader.RecordLoader
      tenant MyApp.Form.DataLoader.TenantResolver
      relation MyApp.Form.DataLoader.RelationLoader
      hooks MyApp.Form.DataLoader.HookRunner
    end

## Defaults

When no overrides are specified, the following defaults are used:

  * `record`   — `MishkaGervaz.Form.Web.DataLoader.RecordLoader.Default`
  * `tenant`   — `MishkaGervaz.Form.Web.DataLoader.TenantResolver.Default`
  * `relation` — `MishkaGervaz.Form.Web.DataLoader.RelationLoader.Default`
  * `hooks`    — `MishkaGervaz.Form.Web.DataLoader.HookRunner.Default`

See `MishkaGervaz.Form.Dsl.DataLoader` for the DSL declaration.
