This article describes how to inject or set variable values from URL parameters.

DisplayWithVariables is a special verb that will inject variable values on navigation.

http://<Host>/Turnkey/DisplayWithVariables?view=<ViewName>&id=<RootId>&vNewVar1=value1&vNewVar2=value2

The URL above will try to find the vNewVar1 variable of type string in <ViewName> - if found, assign the value1 to this variable.

The same will happen for vNewVar2.

Note! Both view and id are required. See below for how to avoid having to send the id.

DisplayWithVariables has been given a shortcut verb. You can now also use this form:

http://<Host>/DWV?v=<ViewName>&i=<RootId>&vNewVar1=value1

The Id of the root object is sent in with "i." If "i" is omitted, null is assumed

These functions now set the ViewModel variable RawURL to the requested URL, including parameters. This makes special processing available to the modeled code.

Sometimes, when we need a callback URL, the DWV is practical. However, some services cannot handle callbacks with parameters (Docusign Authentication)! So the DWV has now been extended so that all these URLs will do the same thing:

https://<server>/Turnkey/AngularApp#/SomeView/2!28   Original
https://<server>/DWV?v=SomeView&i=2!28               How it was - and still is
https://<server>/DWV/SomeView/2!28                   New! DWV/view/id
