RandomDayOfWeek

The RandomDayOfWeek transformer is specifically designed to fill specified database columns with random day-of-the-week names. It is particularly useful for applications that require simulated weekly schedules, random event planning, or any scenario where the day of the week is relevant but the specific date is not.

Parameters

Name	Description	Default	Required	Supported DB types
column	The name of the column to be affected		Yes	text, varchar, char, bpchar, citext
keep_null	Indicates whether NULL values should be preserved	false	No	-

Description

Utilizing the faker library, the RandomDayOfWeek transformer generates names of days (e.g., Monday, Tuesday) at random. This transformer can be applied to any text or varchar column in a database, introducing variability and realism into data sets that need to represent days of the week in a non-specific manner.

Example: Populate random days of the week for the work_schedule table

This example demonstrates configuring the RandomDayOfWeek transformer to populate the work_day column in the work_schedule table with random days of the week. This setup can help simulate a diverse range of work schedules without tying them to specific dates.

RandomDayOfWeek transformer example

- schema: "public"
  name: "work_schedule"
  transformers:
    - name: "RandomDayOfWeek"
      params:
        column: "work_day"
        keep_null: false

In this configuration, every entry in the work_day column will be updated with a random day of the week, replacing any existing non-NULL values. If the keep_null parameter is set to true, then existing NULL values within the column will remain unchanged.
