JSON filters

[marktani]

The ability to filter a node based on the keys or values of a JSON field. Suggestion:

query {
  allPosts(filter: {
    myJsonField: {
      has_key: "myKey"
      int_gte: {
        key: "count"
        value: 23
      }
    }
  }) {
    id
  }
}

would it be possible to filter on Json columns? maybe for just testing if empty or null?

allRecords(filter:{ jsonColumn_empty: true}){ ... }

Could Algolia be used for querying JSON fields?

[jdbence]

Add JSON support using dot notation. Could require depth or exact flat map in the field's settings to limit search.

// Example JSON
{
  "some": {
    "deep": {
      "value": 99
    },
    "nested": [
      {
         "value": 88
      },
      {
         "value": 77
      }
    ]
  }
}

// Filter obj
query {
  allPosts(filter: {
    jsonFieldName.some.deep.value_gte : 23
  }
}) {
    id
  }
}

// Filter array
query {
  allPosts(filter: {
    jsonFieldName.some.nested {
      value_gte : 23
    }
  }
}) {
    id
  }
}

Is this feature still on horizon? Or Would the Implementation for "Interface types" #83 cover this feature?

[johnslemmer]

This is something I'm interested in. But I also think we could start iteratively.

First, I think there needs to be a way to query scalar list fields and Json type fields for whether or not they are null (or unset or emtpy). Maybe something like this:

query {
  allPosts(where: {
    myJsonField_null: true
  }) {
    id
  }
}

Or maybe just providing a raw strict equality and that way you could use the NOT query if you want or even do strict comparison of one JSON value to another.:

query {
  allPosts(where: {
    myJsonField: null
  }) {
    id
  }
}

This seems like something that I hope could happen sooner rather than later without needing to decide on a whole schema for deep Json field queries.

Is there any estimated date for this feature? We really need this!!

[carstenbaumhoegger]

hey! We're also desperately waiting for this to be implemented! @marktani is this still on the roadmap?

Any advice on this feature?

[entrptaher]

Given this mongo schema,

var instanceSchema = new mongoose.Schema({
  name: String,
  data: Array
});

I can push data like below,

var example = new Instance({
  name: "Example.com",
  data: [
    {"Property 1": "Example.com"},
    {"Property 2": "Something else"},
  ]
});

And query like this,

Instance.findOne({
  name: "Example.org",
  "data.2.Property 3": "Something else 3"
})

I cannot find any way to get similar result with prisma/graphql.

I ended up creating my own filter using mingo, but I suppose prisma can implement it somewhere and abstract it away.

[entrptaher]

I needed a solution to filter schemaless Json data (array of objects). So there were two path for me. Either create a schema on the fly, or add some filters manually.

If anyone want's to see the minimal implementation I did for JSON filter, check my playground-json-query-mingo repo.

All suggestions are welcome.

Simple filter:

Complex filter:
