Relative Date Conversios/Inheritance for Query Builder

[norbertbede]

Use Case. Let say I have field dateordered. I select “orderfacts” table - open in query builder, group by dateordered then select Month of year. Error “month-of-year granularity not supported by Cube.js”.

Test Result: Fall - any of relative driver doesn't works, not implemented yet.

• not the best screenshot because here quarter make error, however same just when select e.g Month of Year, then i'm getting "month-of-year granularity not supported by Cube.js"

**I have asked @paveltiunov slack chat **

As a rule of a thumb formatting is usually client side problem. probably related topic: cube-js/cube#177

As get help I made a forum thread in Metabase forum
https://discourse.metabase.com/t/month-of-year-api-for-driver-implementation/9102

The Question: ATM we can’t find way how to convert datefield to relative date formats in metabase driver. (postgres can do this by “commands” Mon, NM, dy, DD, WW…etc. ). We are looking for example code, how to improve the cubejs driver or API doc for handling relative date in driver. (convert/inherit relative dates from a simpe datetime field.) - avoid generate unnecessary fake dimensions.

Meanwhile i found the above piece code in metabase google analytics driver.

then confirmed on google page

This is fixed in your PR #47 , right?

I think this issue is about special granularities eg. (Month of Year, Week of Year) and not Relative DateTime in filter.

You are right, my bad.
