Constructor Details

#initialize(object_creator) ⇒ ModelAdaptor

The adaptor will create an ‘object_creator` callable object. That callable object will be called with a `data_hash` as only argument. The purpose of that callable object is to create an object with the given data.

3 options:

1) object_class_or_creator with the Class of the object to be initiated

sma = ModelAdaptor.single(MyModel)
res = sma.call({a: 1})
res.class           # => MyModel
res                 # => <MyModel a=1>

2) block with 1 argument

sma = ModelAdaptor.with_block do |data|
  { something: data }
end

res = sma.call({a: 1})
res.class           # => Hash
res                 # => {something: {a: 1}}

3) callable object (respond to ‘call`), like a lambda

sma = ModelAdaptor.with_callable( ->(data) { { something: data } })

res = sma.call({a: 1})
res.class           # => Hash
res                 # => {something: {a: 1}}
