Access to objects with indexed associations

ROD allows for accessing objects via associations with indices.

Background
Given
the library works in development mode
Scenarios
  1. indexing of singular associations
  2. indexing of plural associations
  3. indexing of plural associations with fresh objects
indexing of singular associations

It should be possible to index singular associations. This is
useful when there are two databases and the other references
objects from the first, but the first cannot directly reference
objects from the second. In such a case, the second DB can have
indices for the associations to speed-up object look-up.

Given
the class space is cleared
And
a class Caveman inherits from Rod::Model::Base
And
a class Caveman has a name field of type string
And
a class Caveman is connected to Database1
And
a class Automobile inherits from Rod::Model::Base
And
a class Automobile has a name field of type string
And
a class Automobile is connected to Database2
And
a class Caveman has one automobile with flat index
When
the Database1 is created
And
the Database2 is created
And
I create an Automobile
And
its name is 'Prehistoric car'
And
I store it in the database
And
I create a Caveman
And
his name is 'Fred'
And
his automobile is the first Automobile created
And
I store him in the database
And
I reopen Database1 for reading
And
I reopen Database2 for reading
Then
there should be 1 Caveman
And
there should be 1 Automobile
And
there should exist a Caveman with the first Automobile as automobile
And
there should be 1 Caveman with the first Automobile as automobile
indexing of plural associations
Given
the class space is cleared
And
a class Caveman inherits from Rod::Model::Base
And
a class Caveman has a name field of type string
And
a class Caveman is connected to Database1
And
a class Automobile inherits from Rod::Model::Base
And
a class Automobile has a name field of type string
And
a class Automobile is connected to Database2
And
a class Caveman has many automobiles with flat index
When
the Database1 is created
And
the Database2 is created
And
I create an Automobile
And
its name is 'Prehistoric car'
And
I store it in the database
And
I create another Automobile
And
its name is 'Modern car'
And
I store it in the database
And
I create a Caveman
And
his name is 'Fred'
And
his automobiles contain the first Automobile created
And
his automobiles contain the second Automobile created
And
I store him in the database
And
I reopen Database1 for reading
And
I reopen Database2 for reading
Then
there should be 1 Caveman
And
there should be 2 Automobile(s)
And
there should exist a Caveman with the first Automobile as automobiles
And
there should exist a Caveman with the second Automobile as automobiles
And
there should be 1 Caveman with the first Automobile as automobiles
And
there should be 1 Caveman with the second Automobile as automobiles
indexing of plural associations with fresh objects
Given
the class space is cleared
And
the model is connected with the default database
And
a class Automobile has a name field of type string
And
a class Caveman has a name field of type string
And
a class Caveman has many automobiles with flat index
When
database is created
And
I create an Automobile
And
its name is 'Prehistoric car'
And
I create another Automobile
And
its name is 'Modern car'
And
I create a Caveman
And
his name is 'Fred'
And
his automobiles contain the first Automobile created
And
his automobiles contain the second Automobile created
And
I store him in the database
And
I create another Caveman
And
his name is 'Allen'
And
his automobiles contain the second Automobile created
And
I store him in the database
And
I fetch the first Automobile created
And
I store it in the database
And
I fetch the second Automobile created
And
I store it in the database
And
I create another Caveman
And
her name is 'Linda'
And
her automobiles contain the first Automobile created
And
I store her in the database
And
I reopen database for reading
Then
there should be 3 Caveman(s)
And
there should be 2 Automobile(s)
And
there should exist a Caveman with the first Automobile as automobiles
And
there should exist a Caveman with the second Automobile as automobiles
And
there should be 2 Caveman(s) with the first Automobile as automobiles
And
there should be 2 Caveman(s) with the second Automobile as automobiles
