OpenProject Views API

A View is a representation of some information. That information might be a query (currently it always is).The view will store the configuration on how to display the information but not the information itself.A View might then be a graph, a table, a gantt chart or something completely different.The client will have to choose how to represenent in the view. A View instance will always be of a subtype of `Views`, e.g. `Views::WorkPackageslist`. The properties between each `Views` type might differ a lot.**The View is a new concept so it is prone to change.**Currently a lot of restrictions still apply: * There will always be a query associated to the view when in the complete concept, this limitation should not be necessary. * A query can only have one view associated. * There is neither an update nor a delete endpoint and the schema and form endpoints are also missing. To delete a view, simply delete the query. * Most of the properties are deduced from the associated query and can thus only be updated via updating the query. * The properties are not different between `Views` subtypes.## Linked Properties| Link | Description | Type | Constraints | Supported operations || :-------------------: | ---------------------------------------- | ------------- | -------- | -------------------- || self | This view | View (a subtype of it) | not null | READ || query | This query from which to fetch the data | Query | not null | READ/WRITE || project | This project the view is defined in (deduces from the query).
