title: “Customize” description: > Customize Plugin

Summary

This plugin provides users the ability to:

• Add/delete columns in domain layer tables
• Insert values to certain columns with data extracted from some raw layer tables
• Import data from CSV files(only issues and issue_commits two tables are supported)

NOTE: The names of columns added via this plugin must start with the prefix x_

For now, only the following five types were supported:

• varchar(255)
• text
• bigint
• float
• timestamp
• array

Sample Request

Trigger Data Extraction

To extract data, switch to Advanced Mode on the first step of creating a Blueprint and paste a JSON config as the following:

The example below demonstrates how to extract status name from the table _raw_jira_api_issues:

1. For non-array types: Extract the status name from the _raw_jira_api_issues table and assign it to the x_test column in the issues table.
2. For array types: Extract the status name from the _raw_jira_api_issues table, and create a new issue_custom_array_fields table containing issue_id, field_id, and value columns. This table has a one-to-many relationship with the issues table. issue_id is the id corresponding to the issue, x_test corresponds to the field_id column, and the value of x_test corresponds to the value column.

We leverage the package https://github.com/tidwall/gjson to extract value from the JSON. For the extraction syntax, please refer to this docs

• table: domain layer table name
• rawDataTable: raw layer table, from which we extract values by json path
• rawDataParams: the filter to select records from the raw layer table (The value should be a string not an object)
• mapping: the extraction rule; the key is the extension field name; the value is json path

You can also trigger data extraction by making a POST request to /pipelines.

List Columns

Get all columns of the table issues

GET /plugins/customize/issues/fields

NOTE some fields are omitted in the following example response

[
  {
    "columnName": "id",
    "displayName": "",
    "dataType": "varchar(255)",
    "description": ""
  },
  {
    "columnName": "created_at",
    "displayName": "",
    "dataType": "datetime(3)",
    "description": ""
  },
  {
    "columnName": "x_time",
    "displayName": "time",
    "dataType": "timestamp",
    "description": "test for time"
  },
  {
    "columnName": "x_int",
    "displayName": "bigint",
    "dataType": "bigint",
    "description": "test for int"
  },
  {
    "columnName": "x_float",
    "displayName": "float",
    "dataType": "float",
    "description": "test for float"
  },
  {
    "columnName": "x_text",
    "displayName": "text",
    "dataType": "text",
    "description": "test for text"
  },
  {
    "columnName": "x_varchar",
    "displayName": "varchar",
    "dataType": "varchar(255)",
    "description": "test for varchar"
  }
]

Create a Customized Column

Create a new column x_abc with datatype varchar(255) for the table issues.

The value of columnName must start with x_ and consist of no more than 50 alphanumerics and underscores. The value of field dataType must be one of the following 5 types:

• varchar(255)
• text
• bigint
• float
• timestamp

POST /plugins/customize/issues/fields

{
  "columnName": "x_abc",
  "displayName": "ABC",
  "dataType": "varchar(255)",
  "description": "test field"
}

Drop A Column

Drop the column x_text of the table issues

DELETE /plugins/customize/issues/fields/x_test

Upload issues.csv file

POST /plugins/customize/csvfiles/issues.csv

The HTTP Content-Type must be multipart/form-data, and the form should have three fields:

• file: The CSV file
• boardId: It will be written to the id field of the boards table, the board_id field of board_issues, and the _raw_data_params field of issues
• boardName: It will be written to the name field of the boards table

Upload a CSV file and import it to the issues table via this API. There should be no extra fields in the file except the labels field, and if the field value is NULL, it should be NULL in the CSV instead of the empty string. DevLake will parse the CSV file and store it in the issues table, where the labels are stored in the issue_labels table. If the boardId does not appear, a new record will be created in the boards table. The board_issues table will be updated at the same time as the import. The following is an issues.CSV file sample:

id	_raw_data_params	url	icon_url	issue_key	title	description	epic_key	type	status	original_status	story_point	resolution_date	created_date	updated_date	parent_issue_id	priority	original_estimate_minutes	time_spent_minutes	time_remaining_minutes	creator_id	creator_name	assignee_id	assignee_name	severity	component	lead_time_minutes	original_project	original_type	x_int	x_time	x_varchar	x_float	labels
