Class Method Details

.finalize ⇒ DataMapper

Perform necessary steps to finalize DataMapper for the current repository

This method should be called after loading all models and plugins.

It ensures foreign key properties and anonymous join models are created. These are otherwise lazily declared, which can lead to unexpected errors. It also performs basic validity checking of the DataMapper models.

Returns:

def self.finalize
  Model.descendants.each { |model| model.finalize }
  self
end

.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

.root ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

.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]
