Looking to locate an array within a schema using its unique identifier

const FormFieldsSchema = new Schema({
  formName: {
    type: String,
    required: true
  },
  fields: [
    {
      fieldLabel: {
        type: String,
        required: true
      },
      inputData: [{
        type: mongoose.Schema.ObjectId,
        ref: "UserData"
      }]
    }
  ]
});

Hey everyone, I'm facing an issue with a schema where fields is an array and each item has an _id property. I want to update a specific array item based on the _id value, but so far I've been unsuccessful. I've tried using findByIdAndUpdate, as well as parent.inputData.id(_id);, but no success yet. Any suggestions or ideas on how to achieve this?

Answer №1

To simplify querying, convert the array content into a separate model and interact with it directly.

When using findByIdAndUpdate on FormFieldsSchema, remember that it searches for the _id of FormFields, not the content of the fields array.

const FieldSchema = new Schema({
      fieldLabel: {
          type: String,
          required: true
      },
      inputData: [{
          type: mongoose.Schema.ObjectId,
        ref: "UserData"
      }]
})

Update field to fields: [FieldSchema] and don't forget to export FieldSchema as a model.
