Handles async data loading for MishkaGervaz forms.

This module manages:

• Loading records for edit mode
• Creating new AshPhoenix.Form for create mode
• Loading relation options for select fields
• Async result handling

Sub-builders

DataLoader is composed of sub-builders that can be overridden:

• RecordLoader - Loads/creates AshPhoenix.Form
• TenantResolver - Resolves tenant and actions
• RelationLoader - Loads options for relation fields
• HookRunner - Executes lifecycle hooks

User Override

Override the entire data_loader module:

defmodule MyApp.Form.DataLoader do
  use MishkaGervaz.Form.Web.DataLoader

  def load_record(socket, state, record_id) do
    # Custom loading logic
    super(socket, state, record_id)
  end
end

Override specific sub-builders:

defmodule MyApp.Form.DataLoader do
  use MishkaGervaz.Form.Web.DataLoader,
    record: MyApp.Form.RecordLoader,
    relation: MyApp.Form.RelationLoader
end
