Settings in Dynamic Code ✨ new!

The Settings object consolidates settings for the current scenario. It merges settings configured in the View, App, Site, System and Presets. The top-most setting has preference. So if a view overrides a site-setting, the view-setting will be used.

Tip

Learn more about settings and what predefined settings exist in these docs.

There you'll learn about predefined image sizes, google maps keys and more.

Example

Let's assume you have these View-Settings

  • PrimaryColor would be #FF0000
  • Columns would be 4
  • SomeApiKey would be 6n23cnhi502ceh

An these App-Settings

  • PrimaryColor = #CCCCCC
  • SecondaryColor = #00AA00

Then you could get these values from the Settings object

  • @Settings.PrimaryColor would be #FF0000 - found it View
  • @Settings.SecondaryColor would be #00AA00 - only exists in App
  • @Settings.Columns would be 4 - only exists in View
  • @Settings.SomeApiKey would be 6n23cnhi502ceh - from App
  • @Settings.DoesntExist would be null as that data doesn't exist
  • @Settings.Images.Content.Width would be 1400 as it is a preset
Tip

Remember that Settings are meant for configuration and Resources should be used for multi-language output. You could do it differently, but that would be bad practice.

How it Works

The Settings is a dynamic object. Internally the Settings use the new IDynamicStack object to stack entities like sources on each other, and take the first best match. The sources are:

  1. ViewCustom with View-level settings
  2. AppCustom/AppSystem with App-level settings
  3. SiteCustom/SiteSystem with Site-level settings
  4. GlobalCustom/GlobalSystem with System-level settings
  5. PresetSystem with pre-defined settings from the installation
Tip

Read more about this stack and what's in it here Settings Stack in 2sxc ✨ new!. This also includes the full list of sources and their exact names.

The order of the sources is important, as the first match will be returned. The View has priority over the App. This setup allows Views to override App-Defaults.

Accessing Settings from One Source

In rare cases you may want to access settings from a specific source - maybe to detect if it has been changed or because your template explicitly wants the App settings. For this you can use the GetSource(name) method like this:

  • @Settings.PrimaryColor would return #FF0000
  • @Settings.GetSource("ViewCustom").PrimaryColor would return #FF0000
  • @Settings.GetSource("AppCustom").PrimaryColor would return #CCCCCC

History

  1. You could use App.Settings since ca. 2sxc 6
  2. Settings object Introduced in 2sxc 12.02 to consolidate View and App Settings
  3. Settings object was expanded in 12.04 to also cover global, portal and site level settings - see settings docs
