Baconator - TridionPractice/tridion-practice GitHub Wiki

Introduction

I wrote this PowerShell script as I wanted the ability to create lots of Components with random content for test purposes. While searching for "lorem ipsum" alternatives, I came across the meat-flavored baconipsum.com. So I wrote this script to pull down the generator paragraphs and create article Components based on them.

Important: The script requires the Tridion PowerShell Modules available on Google Project.

Details

To use the script, load it using the dot notation:

. .\Baconator.ps1

Then create the Schema by calling Add-SchemaForBaconArticles and passing in the TCM URI of the Folder where you want it to be stored.

Example:

Add-SchemaForBaconArticles -folderId 'tcm:1-2-2'

After that, you can create as many Components as you want by calling Add-BaconArticles and specifying the TCM URI of the Folder where you want them to be stored, and the TCM URI of the Schema created above. Optionally, specify the number of Components to create (the default is 5).

Example:

Add-BaconArticles -folderId 'tcm:1-3-2' -schemaId 'tcm:1-58-8' -numberOfArticles 10

That's all, folks! Use the Baconator with care ;)

The Script

Save the following code as 'Baconator.ps1' in a directory of your choosing:

#Requires -version 2.0

# Allows using relative paths for scripts and other files in the same directory as this script (use Join-Path)
$scriptPath = Split-Path -parent $MyInvocation.MyCommand.Definition
