save

Saves (POST) or updates (PUT) a resource. Delegates to create if the object is new, update if it exists. If the response to the save includes a body, it will be assumed that this body is Json for the final object as it looked after the save (which would include attributes like created_at that weren’t part of the original submit).

Examples

my_company = Company.new(:name => 'RoleModel Software', :owner => 'Ken Auer', :size => 2)
my_company.new? # => true
my_company.save # sends POST /companies/ (create)

my_company.new? # => false
my_company.size = 10
my_company.save # sends PUT /companies/1 (update)
