Noob questions - Extermal Bean Factory

[Dave Shuck]

I am using Taffy for the first time today and am struggling with what I feel should be a simple concept.  I have an external ColdSpring beanfactory, and in the requestStartEvent() I have the following:

<cfset variables.framework.beanFactory = application.beanFactory />

If I go and short-circuit the onRequest() method in the api.cfc with the following...

<cfdump var="#application._taffy.EXTERNALBEANFACTORY.getBean("CityService")#" /><cfabort/>

... I see a dump of a service that I have defined in my ColdSpring instance. 

In the documentation, if I am interpreting it correctly I should then be able to put the following inside one of my resource classes:

<cffunction name="setCityService" output="false" returntype="void" access="public">
      <cfargument name="cityService" required="true" />
      <cfset StructAppend( variables, arguments ) />
 </cffunction>

If this exists, I should then have access to variables.cityService within that resource instance, right?  For some reason, it appears that this isn't working as I would expect.  The setCityService() method is never being invoked.  Am I misunderstanding the way that this works? 

Thanks in advance.

Hi Dave,

Sounds like you're not too far off...

https://github.com/atuttle/Taffy/wiki/So-you-want-to:-Use-an-external-bean-factory-like-ColdSpring-to-resolve-dependencies-of-your-resources#create-your-bean-factory

In short, you should be using ApplicationStartEvent(), not onRequest(), because Taffy has to know about the available services during its bootstrapping phase in order to inject them into the resource CFCs. The above link should get you straightened out. :)

Welcome aboard!

I actually mistyped that.  This is my applicationStartEvent().  Sorry for the confusion!

    <cffunction name="applicationStartEvent" access="public" output="false" returntype="void"
        hint="this method is called by the Traffy framework as a pseudo application bootstrap">
           
        <cfset application.config = loadConfig() />
        <cfset application.beanFactory = initBeanFactory() />

        <cfset variables.framework.beanFactory = application.beanFactory />

    </cffunction>

Hmm, seems reasonable. I don't see anything wrong. Can you share more of your code, or are you available for a quick G+ hangout so I can watch over your shoulder?

Weird, I haven't gotten anything. I'm inviting you to one as well...

Adam, thanks for taking the time to look at the issue with me. In case anyone else runs across this issue, it was related to the lack of an explicit local scope on pre-CF9 during the dependency injection on bootstrap.  The bug fix can be seen here:

https://github.com/dshuck/Taffy/commit/4400cbcabcea98e8b36960ff1efc734a3569165a

[Adam Tuttle]

Thanks for the pull request, Dave. I've accepted it. Anyone running CF8 and using an external bean factory (ColdSpring, etc) will need this, otherwise upgrading is not crucial.

It's available in the BER downloads, but hasn't been included in any tagged versions yet.
