Handle Automatically Generated ExtJS Requests with _id

[bob-obringer]

In some cases, ExtJS automatically generates URLs that contain a reference to a foreign key with _id instead of the entity name.

For example,

In Ext, If you have a Person model that contains a collection of Appointments, the Appointments collection can be loaded on demand if not initially loaded inline with the Person record such as in the following example:
Person.promiseToLoad(12345).then(person => person.appointments().load())

ExtJS automatically generates a request with the following filter parameter:
[{"property":"person_id","value":12345,"exactMatch":true}]

LinkRest responds with the following exception (and partial stack):
c.n.l.r.LinkRestException: Invalid path 'person_id' for 'Appointment' at c.n.l.r.runtime.parser.cache.EntityPathCache.lastPathComponent(EntityPathCache.java:150) at c.n.l.r.runtime.parser.cache.EntityPathCache.getPathDescriptor(EntityPathCache.java:65) at c.n.l.r.runtime.parser.cache.PathCache.getPathDescriptor(PathCache.java:23) at c.n.l.r.runtime.adapter.sencha.SenchaFilterProcessor.process(SenchaFilterProcessor.java:126) at c.n.l.r.runtime.adapter.sencha.SenchaRequestParser.parseFilter(SenchaRequestParser.java:53) at c.n.l.r.runtime.adapter.sencha.SenchaRequestParser.parseSelect(SenchaRequestParser.java:43) at c.n.l.r.runtime.processor.select.ParseSelectRequestStage.doExecute(ParseSelectRequestStage.java:37) at c.n.l.r.runtime.processor.select.ParseSelectRequestStage.doExecute(ParseSelectRequestStage.java:16) at c.n.l.r.processor.BaseLinearProcessingStage.execute(BaseLinearProcessingStage.java:20) at c.n.l.r.processor.ChainProcessor.execute(ChainProcessor.java:18) at c.n.l.r.processor.ChainProcessor.execute(ChainProcessor.java:22) at c.n.l.r.runtime.DefaultSelectBuilder.get(DefaultSelectBuilder.java:204) at c.n.l.r.SelectBuilder.select(SelectBuilder.java:181)

At least within the Sencha adapter, I think LinkRest should be able to consume these automatically generated ExtJS requests.

Closing , as we dropped support for Sencha/Extjs some time ago
