Instance Method Details
#create(attributes = nil, &block) ⇒ Object
Creates an object (or multiple objects) and saves it to the repository, if validations pass. The resulting object is returned whether the object was saved successfully to the repository or not.
The attributes
parameter can be either be a Hash or an Array of Hashes. These Hashes describe the attributes on the objects that are to be created.
Examples
# Create a single new object
User.create(:first_name => 'Jamie')
# Create an Array of new objects
User.create([{ :first_name => 'Jamie' }, { :first_name => 'Jeremy' }])
# Create a single object and pass it into a block to set other attributes.
User.create(:first_name => 'Jamie') do |u|
u.is_admin = false
end
# Creating an Array of new objects using a block, where the block is executed for each object:
User.create([{ :first_name => 'Jamie' }, { :first_name => 'Jeremy' }]) do |u|
u.is_admin = false
end

#eradicate(uri) ⇒ Object
Removes an object’s tombstone so another object with the same uri may be created. NOTE: this is in violation of the linked data platform and is only here as a convience method. It shouldn’t be used in the general course of repository operations.
