@spec configure(Selecto.Types.domain(), term(), keyword()) :: Selecto.Types.t()

Generate a selecto structure from a domain configuration and connection input.

parameters

Parameters

• domain - Domain configuration map (see domain configuration docs)
• postgrex_opts - Connection input retained for backward compatibility. This may be adapter-specific connection options, an Ecto repo, a live connection pid/name, or a pooled connection reference.
• opts - Configuration options

options

Options

• :validate - (boolean, default: true) Whether to validate the domain configuration
• :pool - (boolean, default: false) Whether to enable connection pooling
• :pool_options - Connection pool configuration options
• :adapter - (module, default: SelectoDBPostgreSQL.Adapter) Database adapter module

• :rollup_sort_fix - (true | false | :auto, default: :auto) whether to wrap GROUP BY ROLLUP ... ORDER BY queries in a compatibility subquery; :auto disables the wrapper on PostgreSQL 18+

examples

Examples

# Basic usage (validation enabled by default)
selecto = Selecto.Configuration.configure(domain, connection_input)

# With connection pooling
selecto = Selecto.Configuration.configure(domain, connection_input, pool: true)

# Disable validation for performance
selecto = Selecto.Configuration.configure(domain, connection_input, validate: false)

@spec configure_domain(Selecto.Types.domain()) :: Selecto.Types.processed_config()

Generate the selecto configuration from a domain map.

Processes domain configuration to extract fields, joins, and filters. This is called internally during configure/3.

@spec from_ecto(module(), module(), keyword()) :: Selecto.Types.t()

Configure Selecto from an Ecto repository and schema.

This convenience function automatically introspects the Ecto schema and configures Selecto with the appropriate domain and database connection.

parameters

Parameters

• repo - The Ecto repository module (e.g., MyApp.Repo)
• schema - The Ecto schema module to use as the source table
• opts - Configuration options (passed to EctoAdapter.configure/3)

examples

Examples

# Basic usage
selecto = Selecto.Configuration.from_ecto(MyApp.Repo, MyApp.User)

# With joins and options
selecto = Selecto.Configuration.from_ecto(MyApp.Repo, MyApp.User,
  joins: [:posts, :profile],
  redact_fields: [:password_hash]
)
