Class Method Details

.repository(name = nil) {|Proc| ... } ⇒ Object

Block Syntax

Pushes the named repository onto the context-stack,
yields a new session, and pops the context-stack.

Non-Block Syntax

Returns the current session, or if there is none,
a new Session.

Parameters:

  • args (Symbol) —

    the name of a repository to act within or return, :default is default

Yields:

  • (Proc) —

    (optional) block to execute within the context of the named repository

.setup(*args) ⇒ DataMapper::Adapters::AbstractAdapter

Setups up a connection to a data-store

Parameters:

  • name (Symbol) —

    a name for the context, defaults to :default

  • uri_or_options (Hash(Symbol => String), Addressable::URI, String) —

    connection information

Returns:

Raises:

  • (ArgumentError) —

    “name must be a Symbol, but was…” indicates that an invalid argument was passed for name

  • (ArgumentError) —

    “uri_or_options must be a Hash, URI or String, but was…” indicates that connection information could not be gleaned from the given uri_or_options[Hash, Addressable::URI, String]
