Cannot convert the value of type class coldfusion.runtime.TemplateProxy to a boolean

[Sam]

Hi All,
I'm not really a newbee anymore but this simple code doesn't be
working for some reason. I'm getting the following when I run the
create function. It's the conditional <cfif project.create()> that
giving the problem. I'm validating on the model, <cfset
validatesPresenceOf("projectTitle")>.


Cannot convert the value of type class
coldfusion.runtime.TemplateProxy to a boolean

44 : <cfset project = model("project").create(modParams)>
45 :
46 : <cfif project.create()>
47 : <cfset redirectTo(action="index")>
48 : <cfelse>

Here's the cfwheels code:

<cffunction name="create">
<cfset modParams = structNew()><!---params contains a key named
"id". This is needed for the cfselect tag to produce the dependent
select box effect. I want to rename this key to categoryId so as not
to confuse CFWheels.--->
<cfset modParams.categoryTypeId = #params.categoryTypeID#>
<cfset modParams.categoryId = #params.id#>
<cfset modParams.projectTitle = #params.projectTitle#>
<cfset modParams.description = #params.description#>
<cfset modParams.nonProfitId = #session.currentUser.id#>
<cfset modParams.telecommute = #params.telecommute#>
<cfset project = model("project").create(modParams)>

<cfif project.create()>
<cfset redirectTo(action="index")>
<cfelse>
<cfset renderPage(action="add")>
</cfif>

</cffunction>

create() returns an instance of the object, not a boolean. save() will return a boolean, so I recommend doing something like this:

<cfset project = model("project").new(params.project)>

<cfif project.save()>

</cfif>

Two things:
What do you get when you do:

<cfset project = model("project").create(modParams)>

<cfdump var="#project#">

?

Is it returning a model, or a boolean?

What happens if you do:

<cfset project = model("project").create(modParams)>

<cfif project.hasErrors()>
<cfset renderPage(action="add")>
<cfelse> 
<cfset redirectTo(action="index")>
</cfif>

Second thing would be - would it not be simpler to just alter the params struct, or duplicate it, then delete the key you don't want?
i.e
<cfset modParams=params>
<cfset modParams.nonProfitId = session.currentUser.id> <!--- NB: you don't need the hash signs--->
<cfset modParams.categoryId=params.id>
<cfset structdelete(params, "id")>

Or forget about the modParams struct, and do
<cfset params.categoryId=params.id>
<cfset params.nonProfitId = session.currentUser.id>
<cfset structdelete(params, "id")>

The create() method does not return a boolean value, it returns the object that was created (if it was created successfully).

Thanks to all of the responders.  You guys are so fast!  I didn't realize that create() would not return a boolean, though it was dumping an object.  Problem solved!
Roll on Wheels!!!
