Integrating support for graphene-sqlalchemy-filter into code base

[palisadoes]

As there is limited filtering with graphene-sqlalchemy, I have been using graphene-sqlalchemy-filter which has many stock filters included. Unfortunately the developer seems to have lost interest in the code base and a critical PR to add support for Graphene 3.0 has been unmerged for six months.

• Provide basic support for graphene/graphene-sqlalchemy>=3.0 art1415926535/graphene-sqlalchemy-filter#63

I have tried contacting the developer a few times without response.

As the filtering code for the add-on is contained in the graphene-sqlalchemy-filter package's two files, I propose merging this code into graphene-sqlalchemy.

Would this be OK?

I just followed your link from the filter repo, so I thought I might leave a reply here as well :)

While in general I support the idea of adding filters to graphene-sqa, and like the approach that the author has taken, I think a simple merge won't do it. The filters should be deeply integrated into this repo to allow for even more features, so this has to be planned. But I think using this library as inspiration would be a great start.
Maybe we can work something out together? Or maybe one of the maintainers of this repo has any supporting or opposing ideas to consider before starting. It would be sad to see yet another merge request get stuck unapproved for a long time.

Thanks. My python skills are good, but not great. However, I'd be willing to learn. @cooldudemcgeexl would you be interested in a collaboration?

We have an interested party in adding the filtering syntax.

Sounds great!

I think the current external library is great but still has some places where the design lacks flexibility.
Maybe we should find some interested users and collect their filtering requirements here as a start?

@sabard and @PaulSchweizer are working on a requirements Google Doc to help determine the expected time and cost. Join us on the #graphene-sqlalchemy-filter channel on the Graphene Slack organization. The link can be found here https://github.com/graphql-python/graphene

The starting point would be to mimic the API interface that the graphene-sqlalchemy-filter currently provides. Let us know what flexibility you'd like to see and add it to the doc.

Implementation is in progress. The main PR will be #357. Please join us on Slack #graphene-sqlalchemy-filter if you would like to contribute or have anything to add!
