Multiple @where directives on a single field

[cwhitby]

Is your feature request related to a problem? Please describe.

It would be great if we could apply multiple @where directives to a single field.
For example:

input AuditFilterInput {
    date_after: Date @where(operator: ">=", key: "date") @where(operator: ">=", clause: "orWhere", key: "created_at")
}

In this case, only the first directive is applied.

Describe the solution you'd like

I can think of 3 options:

A) Allow multiple instances of the @where directive. I don't think any other directive allows this either so there might be a limitation in the core of Lighthouse.

B) Allow the @where directive to accept an array of conditions, in a similar format to how the Laravel Query Builder does.

C) This behaviour already exists somewhere and I just can't see it in the docs.

Curious to see what others think.

Have you actually tried this in the most recent version of Lighthouse? I agree that this should work.

It was originally tested using version 3.7.0, I've just checked again using 4.0-alpha.2 with the same result.

Can you provide a PR with a failing test case in https://github.com/nuwave/lighthouse/blob/master/tests/Integration/Execution/BuilderTest.php please?

We can enable this feature (and possibly other use cases of applying the same directive repeatedly) once the spec allows it: graphql/graphql-spec#472

Changed handling of the argument filters makes this work for @where now, at least #834 passed for now.

General availability and proper documentation of repeatable directives will be tracked in #1133.

Feel free to reopen if you still experience issues.
