Sitecore PowerShell Script to Update renderings cacheable setting to true

Prerequisites: Sitecore PowerShell Extensions

Recently came across this PowerShell script that lists all renderings irrespective of if Cacheable  is set to true or false:

https://gist.github.com/michaellwest/b4352327d13447c427cf

In order to just list the renderings where Cacheable is set to true, just added an extra condition like this:

$VerbosePreference = "continue"

$path = "master:/sitecore/layout/renderings"

Write-Log "Get all renderings and determine if caching is enabled."

Get-ChildItem -Path $path -Recurse | 

    Where-Object { $_.TemplateName -ne "Rendering Folder" -and $_.Cacheable -eq "1"} | 

    Format-Table -AutoSize -Property Name, ItemPath, ID, @{"Name"="Cacheable";"Expression"={$_.Cacheable -eq "1"}}

Going a step ahead, I wanted to build an Update Script that will automatically set the Cacheable checkbox to true. So, came up with this script:

$VerbosePreference = "continue"

$path = "master:/sitecore/layout/renderings"

Write-Log "Get all renderings and update cacheable to true."

 foreach($item in Get-ChildItem -Path $path -Recurse | 

Where-Object { $item.TemplateName -ne "Rendering Folder" }) {

    $item.Editing.BeginEdit()

    $item.Fields["Cacheable"] = "1"

    $item.Editing.EndEdit() | Out-Null

  }

Write-Log "Update Complete."

Don't forget to add a narrower path to $path variable else all renderings will be set to cacheable true!
