I'm pleased to announce that we have released DataMapper 1.1.
This has been one of the most enjoyable releases in recent memory. The
community rallied together and compared to the previous release we had
at least 3-4x more people submitting patches and working together to
get this release ready.
DataMapper 1.1 brings several minor API changes, warranting the minor
version bump, and closes 52 tickets in Lighthouse. There have been
many performance improvements, some closing bottlenecks that result in
as much as a 20x speedup from the 1.0.2 behaviour.
As part of the bug fixing process we've refactored some of the objects
we use internally to group relationships and dependencies and removed
methods and classes that were deprecated in 1.0.
DataMapper can be installed with a one-line command:
$ gem install datamapper dm-sqlite-adapter --no-ri --no-rdoc
The above command assumes you are using SQLite, but if you plan to use
MySQL, PostgreSQL or something else replace dm-sqlite-adapter with
your preferred adapter gem.
Here's a list of the tickets we've resolved for 1.1:
* ActiveSupport / Extlib dependency is removed. If your code relies on
one of these libs then just add a dependency on your own.
* DataMapper::Type is gone now in favour of DataMapper::Property. The
Type API was deprecated in 1.0 but if you still have some Types
floating around read how to upgrade them here:
* RelationshipSet and PropertySet are now subclasses of a new
SubjectSet class - more info:
Please be aware that previously RelationshipSet and PropertySet
inherited from Hash and Array, respectively.
* Property class finder is now improved and it's possible to declare
properties that aren't defined in DataMapper::Property namespace
without providing the full const path. For instance you can have
YourApp::Properties::FooBar and you can declare it as
"property :foo_bar, FooBar". There's a convention that if your
property class has the same name as one of the other properties from
DataMapper::Property namespace then you have to provide the full const
path, otherwise your property won't be found.
* Removed deprecated methods:
DataMapper::Collection#add (replaced by #<<)
DataMapper::Collection#build (replaced by #new)
DataMapper::IdentityMap#get (replaced by #)
DataMapper::IdentityMap#set (replaced by #=)
DataMapper::PropertySet#has_property? (replaced by #named?)
DataMapper::PropertySet#slice (replaced by #values_at)
DataMapper::PropertySet#add (replaced by #<<)
DataMapper::Query::Conditions::Comparison#property (replaced by
DataMapper::Query::Direction#property (replaced by #subject)
DataMapper::Query::Direction#direction (replaced by #operator)
DataMapper::Property#unique (replaced by #unique?)
DataMapper::Property#nullable? (replaced by #allow_nil?)
DataMapper::Property#value (replaced by #dump)
DataMapper::Resource#new_record? (replaced by #new?)
