Invalid .query() from odata-v4 dataSource

[VAFIR]

Working with Kendo UI version 2016.2.504, I have tested two filtering method calls across the same odata-v4 dataSource:

1. via .filter() - gridStage.model.DS.filter(DSfilter()) results in:

/app/odata/vwgriddc_info?%24format=json&%24orderby=dc_name&%24filter=dc_id+eq+109&%24count=true

2. via .query() - gridStage.model.DS.query(DSfilter()) results in:

/app/odata/vwgriddc_info?%24format=json&logic=and&filters%5B0%5D%5Bfield%5D=dc_id&filters%5B0%5D%5Boperator%5D=eq&filters%5B0%5D%5Bvalue%5D=109&%24count=true

 

The former works perfectly; the latter fails to properly encode the filter in odata-v4 format and ignores the existing sort parameter. 

I would prefer to render the return within the .query().then() promise, but have worked around the problem with .filter() and requestEnd/setTimeout.

 

Are there plans to update .query() to support odata-v4?  Or, is there some other sort of work around to this issue.

Thanks!

Hello VAFIR,

The difference between the filter and query method is that the later expects an object which contains the appropriate filter, sort, group descriptors and paging information. Where the filter method expects only the filters. Therefore, you cannot pass the filter descriptors directly to the query method, but you need to construct the correct argument value. Please refer to the documentation for more details.

Thank you for the assistance, Rosen.  Got it going.  A couple of documentation comments:

1.  The query method documentation should explicitly state that it over-writes all the related dataSource configuration.  IE., a query call without a sort property will actually set the dataSource sort property to {}, not the behavior one would expect from an "optional" parameter.

2. The sort method, like filter, can set or get the dataSource property.  The documentation only states that the sort method sets the property.

Thanks again!

Hello VAFIR,

Thanks for the suggestion. We will add such note to the documentation.

Regarding the sort method it seems OK to me. Maybe I'm missing something.

Naw, I was prolly looking at the sort property rather than the method.
