I just wanted to give an update on the ruby_odata progress. If you don’t know about ruby_odata or want a refresher, I blogged about it a few weeks ago. Anyway, I just released a new version of the gem, v0.0.7. With this new version, you can now perform batch saves (multiple adds, deletes, and updates) and types are being supported. The library is getting more mature with each revision. Below is the state of the current gem:
dynamic methods are available after you instantiate the service. You can chain query operations like **order_by**, **filter**, **expand**, etc. on to the dynamic methods.
- For querying, $orderby, $top, $skip, $filter, and $expand are supported. These are represented by the methods order_by, top, skip, filter, and **expand **(respectively) on the OData::QueryBuilder class (which is returned from the dynamic collection methods), for example:
- The ability to add entities. **AddTo
** dynamic methods are available after you instantiate the service, allowing you to pass new entities to the methods.
- The ability to update entities though the update_object method on the OData::Service.
- The ability to delete entities though the delete_object method on the OData::Service.
- The ability to batch saves, which allows you to pass multiple objects to be added, updated, or deleted and have them persisted as a batch when you call the save_changes method on the OData::Service. Note that with batch saves, the changes either complete or fail as a batch.
- Explicit data type support for the following: (Everything outside of this list currently is represented as a string.)
- Support for Complex Types – From OData.org: “**Complex Types** are structured types also consisting of a list of properties but with no key, and thus can only exist as a property of a containing entity or as a temporary value.” You’ll typically see these to logically group properties together. For example, with the Netflix service, they expose a BoxArt complex type on a Title. The BoxArt type consists of 3 properties, SmallUrl, MediumUrl, LargeUrl. This makes accessing these clearer and cleaner, for example
- Works with Ruby 1.8.7 and Ruby 1.9.1. It also works with ActiveSupport 3.0.0.beta4. These were tested on Windows due to using WCF Data Services for the test suite, although, if something Ruby works in Windows there is a good chance everything should be fine on Mac or Linux as well. I could always change the test URLs to point at a remote machine to do my testing on a Mac, but I wish there was an OData producer like WCF Data Services that would work with ActiveRecord (or similar).
