cfspec has method with CF9 ORM

July 21, 2009

I've been hacking cfspec again! I'm working on a application which takes advantage of the ORM capabilities of ColdFusion 9. ColdFusion generates the getters and setters for you for each property of a persistent entity. Because of this, If you write the following test it will fail.


<cfimport taglib="/cfspec" prefix="">
<describe hint="model.foo.Bar Specification">

  <beforeAll>
    <cfscript>
    // runs once before any "it" block
    
    // load object but don't fire constructor
    ClassInstance = CreateObject( "component", "model.foo.Bar" );
    
    </cfscript>
  </beforeAll>
  
  <describe hint="Methods">
    
    <it should="have a setName method">
      <cfscript>
      $( ClassInstance ).shouldRespondTo( "setName" );
      </cfscript>
    </it>
    
  </describe>
  
</describe>

What cfspec does is to look at the functions information in the class metadata so it doesn't find the method you're looking for as generated methods are not reported.

You can get cfspec to recognise the method names by modifying the hasMethod function in cfspec/lib/Base.cfc. here is my modified version


  <cffunction name="hasMethod" output="false">
    <cfargument name="obj">
    <cfargument name="methodName">
    <cfset var metaData = getMetaData(obj)>
    <cfset var funcs = "">
    <cfset var func = "">
    <cfset var properties = "" />
    
    <cfloop condition="structKeyExists(metaData, 'extends')">
      <cfif isDefined("metaData.functions")>
        <cfset funcs = metaData.functions>
        <cfloop array="#funcs#" index="func">
          <cfif func.name eq methodName>
            <cfreturn true>
          </cfif>
        </cfloop>
      </cfif>
      <!--- added to handle generated methods for persisted entities --->
      <cfif isDefined("metaData.properties") 
        and isDefined("metaData.Persistent") 
        and metaData.Persistent>
        <cfset properties = metaData.properties >
        <cfloop array="#properties#" index="func">
          <cfif ListFindNoCase( "remove#func.name#,#Left(methodName,3)##func.name#", methodName ) neq 0>
            <cfreturn true>
          </cfif>
        </cfloop>
      </cfif>
      <!--- end of modified code --->
      <cfset metaData = metaData.extends>
    </cfloop>

    <cfreturn false>
  </cffunction>

The above works nicely, but isn't perfect. Ideally I should be checking to see if the property has a setter or getter attribute set to false. Also, I should really check for relationships & it's type for the addXYZ(), hasXYZ() and removeXYZ() methods. Maybe when I have a bit more time!
