allow null in input list

[altaurog]

I would like to be able to create a range search parameter as a list of possibly null values, so I could do something like the following:

range	query
amps < 3	components (amps: [null, 3])
1 < amps < 3	components (amps: [1, 3])
1 < amps	components (amps: [1, null])

Input List type doesn’t seem to allow this. I get an Unexpected Name "null" error

[altaurog]

In this case I could just use a string with comma-separated values:

range	query
amps < 3	components (amps: ",3")
1 < amps < 3	components (amps: "1,3")
1 < amps	components (amps: "1,")

But I would lose some type safety that way. It seems to me that null would be useful as a legal value in any case.

@altaurog graphene is powered by graphql-core which is an almost direct port of the graphql-js library for node. graphql-core doesn't support null yet but there is an open issue (graphql-python/graphql-core#118) and a potential pull request open (graphql-python/graphql-core#172) for it.

I'm going to close this issue in favour of tracking progress in the graphql-core repo.

@jkimbo thanks! I’ll have a look there.

Aforementioned issues have been removed. Is it truly fixed?

@antwan Graphene v3 uses the new v3 version of graphql-core which has full support for nulls. We’re hoping to release the new version soon but in the meantime there is a beta version that you could use.
