[JSON] Support Edit Values for JSON operator #1132

ShihChun-H · 2024-10-09T15:04:49Z

Issue Description

Current State

It is very difficult to manipulate JSON data with JSON operator.

Proposed Change

Please fetch this JSON Schema to implement the functions.

JSON schema pseudo code

JsonOperator:
  Task: Edit values
  
  Input:
    data: 
      type: object
      description: Original data, which can be a JSON object or array of objects.
    updates: 
      type: array
      description: An array of objects specifying the values to be updated.
      items:
        type: object
        properties:
          field: 
            type: string
            description: The field in the original data whose value needs to be updated, supports nested paths if "supportDotNotation" is true.
          newValue: 
            type: any
            description: The new value that will replace the current value at the specified field.

#    supportDotNotation:
#     type: boolean
#      default: true
#      description: Determines whether to interpret the field as paths using dot notation. If false, field is treated as a literal key.
    conflictResolution:
      type: string
      enum: [create, skip, error]
      default: skip
      description: Defines how to handle cases where the field does not exist in the data. 
      
  Output:
    data:
      type: object
      description: The modified data with the specified values updated.

Edge Cases and Considerations:

1. Non-Existent Fields:

You might decide to skip updates where field does not exist in the data or log a warning for such cases.

2. Type Mismatches:

Ensure that the new value is compatible with the existing data structure (e.g., if replacing an array with an object, ensure the change is intended).

Key Features:

field: This specifies the exact location of the value to be edited. It allows for nested paths (e.g., address.city); otherwise, it treats the path as a literal key.
newValue: This is the new value that will replace the current value at the specified field.
conflictResolution Parameter:
a. create: If the field does not exist, the function creates it.
b. skip: If the field does not exist, the function skips the update (default behavior).
c. error: If the field does not exist, the function logs an error or returns an error.

Type Checking:
Before updating a value, the type of the existing field is checked to ensure compatibility.

Example Usage:

Scenario: Input data as JSON object

// input
{
  "data": {
    "name": "John Doe",
    "age": 30,
    "address": {
      "street": "123 Main St",
      "city": "Anytown",
      "state": "CA"
    },
    "contacts": [
      {
        "type": "email",
        "value": "[email protected]"
      },
      {
        "type": "phone",
        "value": "555-1234"
      }
    ]
  },
  "updates": [
    {"field": "name", "newValue": "Jane Doe"},
    {"field": "address.city", "newValue": "Othertown"},
    {"field": "age", "newValue": "31"},
    {"field": "address.zipcode", "newValue": "12345"},
    {"field": "contacts.0.value", "newValue": "[email protected]"}
  ],
//  "supportDotNotation": true,
  "conflictResolution": "skip"
}

Conflict Resolution Scenarios:

1. Skip (Default):

Field "name": "John Doe" is updated to "Jane Doe".
Field "address.city": "Anytown" is updated to "Othertown".
Field "age": "30" is updated to "31".
Field "address.zipcode": "zipcode" field does not exist initially. Since conflictResolution is "skip", the update is skipped, and "zipcode" is not added.
Field "contacts.0.value": "[email protected]" is updated to "[email protected]".

Final output:

{
  "name": "Jane Doe",
  "age": 31,
  "address": {
    "street": "123 Main St",
    "city": "Othertown",
    "state": "CA"
  },
  "contacts": [
    {
      "type": "email",
      "value": "[email protected]"
    },
    {
      "type": "phone",
      "value": "555-1234"
    }
  ]
}

2. Alternate Scenario with "conflictResolution": "create":
If you had set "conflictResolution": "create", the "zipcode" field would have been created in the "address" object, and the output would look like this:

Final output:

{
  "name": "Jane Doe",
  "age": 31,
  "address": {
    "street": "123 Main St",
    "city": "Othertown",
    "state": "CA",
    "zipcode": "12345"
  },
  "contacts": [
    {
      "type": "email",
      "value": "[email protected]"
    },
    {
      "type": "phone",
      "value": "555-1234"
    }
  ]
}

3. Error:
If the conflictResolution is set to "error", the function will raise an error (or log an error) when it encounters a non-existent field during the update process. In this case, the update process will stop as soon as the non-existent field is encountered, and the existing fields will not be updated beyond that point.

// In this case, the function would return an error, and the output would likely look something like this:
  "error": "Field 'address.zipcode' does not exist."

Scenario: Input Data as an Array of Objects
If the input data is an array of objects, the logic needs to be adapted to handle each object in the array individually. The schema and the function would process each object within the array according to the specified updates and conflictResolution rules.

Input Example:

{
  "data": [
    {
      "name": "John Doe",
      "age": 30,
      "address": {
        "street": "123 Main St",
        "city": "Anytown",
        "state": "CA"
      },
      "contacts": [
        {
          "type": "email",
          "value": "[email protected]"
        },
        {
          "type": "phone",
          "value": "555-1234"
        }
      ]
    },
    {
      "name": "Jane Smith",
      "age": 28,
      "address": {
        "street": "456 Oak St",
        "city": "Othertown",
        "state": "NY"
      },
      "contacts": [
        {
          "type": "email",
          "value": "[email protected]"
        }
      ]
    }
  ],
  "updates": [
    {"field": "name", "newValue": "Updated Name"},
    {"field": "address.city", "newValue": "New City"},
    {"field": "contacts.0.value", "newValue": "[email protected]"},
    {"field": "age", "newValue": 29}
  ],
//  "supportDotNotation": true,
  "conflictResolution": "create"
}

Explanation:

Field "name": Updates "name" to "Updated Name" for each object in the array.
Field "address.city": Updates the "city" in the "address" for each object to "New City".
Field "contacts.0.value": Updates the first contact's value to "[email protected]" in each object.
Field "age": Updates the "age" field to 29 for each object.

Output:

{
  "data": [
    {
      "name": "Updated Name",
      "age": 29,
      "address": {
        "street": "123 Main St",
        "city": "New City",
        "state": "CA"
      },
      "contacts": [
        {
          "type": "email",
          "value": "[email protected]"
        },
        {
          "type": "phone",
          "value": "555-1234"
        }
      ]
    },
    {
      "name": "Updated Name",
      "age": 29,
      "address": {
        "street": "456 Oak St",
        "city": "New City",
        "state": "NY"
      },
      "contacts": [
        {
          "type": "email",
          "value": "[email protected]"
        }
      ]
    }
  ]
}

Just a few questions.

Is this supposed to be a task that needs to be added in Json Operator? If it is could you confirm if the following are the stuffs that need to be done

Add task in definiton.json
Create Schema for task in tasks.json
Implement interface for the task in main.go

Is there anyway i can check the working of the task interface in main.go without having to create a pipeline

kuroxx · 2024-10-15T10:22:21Z

@chuang8511 could you please help answer the technical questions here 🙏

chuang8511 · 2024-10-15T12:15:04Z

Is this supposed to be a task that needs to be added in Json Operator? If it is could you confirm if the following are the stuffs that need to be done

Yes, actually, we have helped you finish the tasks.json & definition.json. So, what you have to do is only develop the golang code.

branch

Is there anyway i can check the working of the task interface in main.go without having to create a pipeline

Usually, I create test code. You can refer to the main_test.go in some directory. In this way, you do not have to create the pipeline to do end to end test at the first place.

@chuang8511 Just a quick question

I have some trouble trying to create a recipe for this component

I have been trying something like this
variable:
test1: # Unique identifier for the variable.
instill-format: # Format type, e.g., image, string, array:string.
title: Json Input # Title of this input field.
description: Test values

instill-format doesnt seem to support object type.

Do you know any recipe that uses json value as input which i could refer?

chuang8511 · 2024-10-24T16:25:13Z

It seems there is a bug fix a few days ago.
Could you rebuild your instill-core?

Sample

# VDP Version
version: v1beta
variable:
  json-string:
    title: JSON
    instill-format: json

component:
  json-0:
    type: json
    input:
      json: ${variable.json-string}
    condition:
    task: TASK_MARSHAL  

output:
  result:
    title: Result
    value: ${json-0.output.string}

Prototype4988 · 2024-10-25T17:48:28Z

@chuang8511
I am trying something like this. looks like there is no support for instill-format: array:json.

Any workaround you could suggest.

variable:
  json-string:
    title: JSON
    instill-format: json
  updatearray:
    title: Update
    instill-format: array:json
  conflict:
    title: conflict Resolution
    instill-format: string
  supportdot:
    title: support supportDotNotation
    instill-format: boolean

component:
  json-0:
    type: json
    input:
      json: ${variable.json-string}
      updates: ${variable.updatearray}
      conflict-resolution: ${variable.conflict}
      supportDotNotation: ${variable.supportdot}
    task: TASK_EDIT_VALUES

output:
  result:
    title: Result
    value: ${json-0.output.string}

Hi @Prototype4988 ,
sorry to reply late.

How about trying this?

# VDP Version
version: v1beta
variable:
  json-string:
    title: JSON
    instill-format: string

component:
  json-0:
    type: json
    input:
      string: ${variable.json-string}
    condition:
    task: TASK_UNMARSHAL  

  json-1:
    type: json
    input:
      json: ${json-0.output.json}
    condition:
    task: TASK_MARSHAL  

output:
  json-0:
    title: JSON 0
    value: ${json-0.output.json}
  json-1:
    title: JSON 1
    value: ${json-1.output.string}

Prototype4988 · 2024-10-30T16:32:44Z

@chuang8511 It works but my question is how do i pass array of json as input since it looks like there is no support for instill-format: array:json

Hi @kuroxx

There is a bug as mentioned below which is a blocker against the development of the component

@chuang8511 It works but my question is how do i pass array of json as input since it looks like there is no support for instill-format: array:json

Will try to complete it within end of week provided there is a resolution or work around for the bug.

@chuang8511 do you have any suggestions on the issue?

kuroxx · 2024-11-05T09:25:15Z

Hey @Prototype4988

Could you check the documentation about Instill Format here.

In general, you do not need to specify the array, you can just set it as json.

For example:

Input:

[ 
  { "name": "Jane",  "surname": "Doe" },
  { "name": "Bob", "surname": "Woe"}
]

Recipe:

# VDP Version
version: v1beta

variable:
  json-input: 
    title: json-input
    instill-format: json
    description: "Your JSON input."

output:
  json-output:
    title: json-output
    value: ${json-1.output.string}

component:
  json-1:
    type: json
    input:
      json: ${variable.json-input}
    condition:
    task: TASK_MARSHAL

Result:

You can read about how to use JSON Marshal in the Documentation here too

Let me know if this answers your questions ✨
