Variables. scope inside of a cfmodule

Question

I have a page with a name of

summary.cfm

inside of it:

 <cfinclude template="view/totals.cfm>

view/totals.cfm

inside of it:

variables.grandTotalHTML = invoke("viewtotals, "doSummary", {...});

view/viewtotals.cfc

inside of it

<cfmodule template="summarytemplate.cfm" ...>
<!--- database is not passed in here --->

view/summarytemplate.cfm

Inside of it we have

param attributes.database = session.database;
...
databaseoverride = attributes.database;
...

<cfquery name="qData">
   SELECT *
   FROM [#variables.databaseoverride#]
   ...
</cfquery>

Now question

I don't know where the databaseoverride is coming from.

1. Does global page request scope?
2. Does it come from variables in viewtotals.cfc ?
3. Does the unscoped version override it?

Answer 1

(Too long for comments)

Just to elaborate on Dan's answer:

summary.cfm

• Only shares a VARIABLES scope with the included template, "view/totals.cfm"

view/totals.cfm

• Only shares a VARIABLES scope with the parent template, "summary.cfm"

view/viewTotals.cfc

• Its VARIABLES scope is not shared with any of the calling templates (summary.cfm and view/totals.cfm)

• Its VARIABLES are accessible to the cfmodule - through the CALLER scope (as are the function's local and arguments scopes)

view/summaryTemplate.cfm

• Does not share its VARIABLES scope with anyone.
• Can view/modify any scopes in the parent component (viewTotals.cfc) through the CALLER scope.

( The REQUEST scope is accessible to all of the scripts above.)
