About UA EDS

UA EDS is a gem that provides a wrapper to basic EDS DSML/JSON endpoint functionality as provided by the UA.

The code isn't the most beautiful and test coverage is mediocre, and it probably has one or 2 gotchas, but it works.

The tests mostly cover integration, not line by line units. It is perfectly possible to mock documents for unit testing by monkey patching in a method to set the local document to a particular value, but it hasn't been done. Consider it a todo.


You have a choice between EdsDSML and EdsJSON. The difference is that DSML requires access to the DSML API endpoint and abstracts an XML document to find properties, while JSON uses a JSON-providing endpoint and abstracts JSON parsed into a hash.

Either way, you need to provide an endpoint, EDS user, and access key for library to use.

EdsDSML.eds_user = <user>
EdsDSML.eds_key = <key>
EdsDSML.eds_endpoint = "https://<endpoint>"
eds = EdsDSML.instance
person = eds.person_by_netid(<netid>)
# ...

Whether you choose JSON or DSML endpoints, it works pretty much the same way.

To get an unmapped attribute, use .lookup_value('camelCaseValue'), which should return nil for unvalued items.

If a document isn't found, rather than getting nil or an error back, all values on the retreived object should be nil. (Less than ideal.)

If using the JSON flavor, it's possible that a poorly formed request will grab multiple results and trigger an ArgumentError: Argument is not a hash. (Once again, currently less than ideal.)


Currently, bundle exec rspec spec is the way to run tests. (No rake job yet.) It wil prompt for EDS user name, EDS key, DSML endpoint, JSON endpoint, and a 'NetID' for testing purposes.

If you feel lazy, it should work if you create a file formatted like:

<DSML endpoint>
<JSON endpoint>
<Test NetID>

and run bundle exec rspec spec <, though you might get some stty: standard input: Inappropriate ioctl for device messages.

The tests themselves are currently ugly - not a whole lot of experience with rspec yet.
