Map Values as Scalars Support

[xsoufiane]

Currently, Sangria doesn't support map values as scalars. The choice was made to preserve security, e.g., prevent NoSQL Injections as discussed here. However, to be able to use Apollo federation on top of Sangria, there is a need for accepting map values (json objects) as scalars. The federation issue was raised here.

Now, I opened this issue to keep track of the efforts that are being done to solve it without opening the security hole.

Details

Let's consider the following schema:

scalar _Any
type Query {
  _entities(representations: [_Any!]!): [_Entity]!
} 

By solving this issue, we will be able to perform the following queries:

{
  "query": "query($representations: [_Any!]!) {...}"
  "variables": {
    "_representations": [
      {
        "__typename": "Product",
        "upc": "B00005N5PF"
      },
      ...
    ]
  }
}

or using the input object notation:

{
  _entities(representations: [{__typename: "State", id: 0}]) {...}
}
