ListField

[Burhan GÖKSEL]

Greetings To You All,

The mongoengine we use for work gives list fields not type error in the documents I create.

For example:

Code:

class Y(EmbeddedDocument):

id = StringField()

name = StringField()

class X(Document):

author = StringField()

y = ListField(EmbeddedDocumentField(Y))

query :
{x{
  id,
  author,
  y
}}

error message :

      "message": "Cannot query field 'y' on type 'XOutput'.",

Thank you very much in advance to those who help.

Why don't you use embedded document list field

y = ListField(EmbeddedDocumentField(Y)) to y = ListField(DictField()) solved problem. But read operation is running, but the create is not.

Query =

mutation{
  createX(
    artifact:{
  name :"student",
    y: [{name:"burhan"]
    }
  ){
    x{
      id
    }
  }
}

my document =

class X(Document):

author = StringField()

y = ListField(DictField())

Error messages =

"message": "ValidationError (Artifact:None) (Only dictionaries may be used in a DictField: ['y'])",

You may have a typo in your mutation:

     y: [{name:"burhan"]

    }

Should be

     y: [{name:"burhan"}]

    }

Nevertheless, Pryia's suggestion of using an embedded doc field seems correct and is probably better in the long run if you want to have validations on the list items.

Thanks for support.  The problem was in the query I sent :).
