copy transfer object to another transfer object

[Jim Rising]

I'm needing to copy one TO to another TO, and wondered if anyone had any ideas on the best way to do that? Basically I have one TO that needs to serve as a 'template' of another.

Example:

I have a TO called 'contentTemplate' and another called 'content'.
I want to be able to create a 'content' object from the 'contentTemplate' object.

I'm thinking I will need to just get / set everything between each of them, but was hoping I would have another option available.

Thanks!

Someone who knows a little more detail about how the caching works may say what I suggest is a bad a idea, but here's a method I've used with no issues yet.

Inside the decorator I've used the TO.setTransferObject(otherTO) method. Though both the setting object and the TO object are both the same (IE: content/content).

Another idea may be to use setMemento(mementoStruct)

It's not really recommended to use getMemento() and setMemento() in your own code - they are meant for internal use.  I created my own version of getMemento() that is safe to consume, and I also have a populate() method that could be used as a replacement for setMemento().  You can find references to both on my blog.

Cheers,
Bob

ok... so here is what I did in my decorator:

    <cffunction name="copyContentTemplate">
        <cfargument name="contentTemplate" type="transfer.com.transferObject" required="true">
<cfset var contentTemplate = arguments.contentTemplate>
        <cfset var content = getTransfer().get("content.Content", "")>
       
        <cfset content = setTransferObject(contentTemplate)>
    </cffunction>

now... this does seem to copy a 'contentTemplate' TO into a 'content' TO without any issues, but when i attempt to save using the following:

    <cffunction name="saveContent" access="public" returntype="any">
        <cfargument name="content" type="transfer.com.transferObject" required="true">
        <cfset var content = arguments.content>

        <cfset getTransfer().save(content)>
       
    </cffunction>

the object does not save.

any ideas?

Probably because you are using a variety of undocumented badness :o(

getMemento() , switching out the inner object if a Decorator... all sounds pretty bad if you ask me.

I think Bob's approach of using his memento function is probably the way to go.

Mark,

Thanks. I'll look into it a bit further.

I'm actually running into issues of losing my decorator methods after using the setTransferObject(TO). I haven't had time to debug yet (as this is not a production app yet).

I do this inside a "myDecoratedObject" called someobject:

<cfset TO = getTransfer().readByPropertyMap("myDecoratedObject",filter) />

<cfif TO.getIsPersisted()>

  <cfset setTransferObject(TO) />

<cfelse>

 <!--- code that initializes this object based on the filter and saves it --->

</cfif>

After running this code, randomly (haven't investigated yet; believe it somehow related to my filter). "someobject" loses all of its decorator methods until I clear the transfer cache.

Bob, I read your blog post:

http://www.silverwareconsulting.com/index.cfm/2008/7/22/How-I-Use-Transfer--Part-IX--My-Abstract-Transfer-Decorator-Object--The-Populate-Method

And i think I will try that out whenever I go back to working on my project. Thanks for the tip!

Mark, any plans for implementing something similar?

Thanks,

John

I came here today for the specific reason of asking this same
question! Thanks! :)

[Bob Silverberg]

I'm sure Mark will correct me if I'm mistaken, but I don't think you should be calling setTransferObject() in your code.  I'm guessing you could get yourself into all kinds of trouble.

what about listColumns() ?

    <cffunction name="copyTransferObject" output="false" hint="I copy one transfer object to another">
        <cfargument name="aObject" required="true" type="transfer.com.TransferObject">
        <cfargument name="bObject" required="true" type="transfer.com.TransferObject">
        <cfset var aObject = arguments.aObject>
        <cfset var bObject = arguments.bObject>
       
        <cfset bColumns = bObject.listColumns()>
        <cfloop list="#bColumns#" index="columnName">
            <cfset getter = "aObject.get#columnName#()">
            <cfset columnValue =  Evaluate(getter)>
            <cfset setter = 'bObject.set#columnName#("#columnValue#")'>
            <cfset Evaluate(setter)>
        </cfloop>
        <cfreturn bObject />
    </cffunction>

Hmm, I've never even heard of listColumns().  If it were me, I'd use the metadata that Transfer makes available for just this purpose. In case you didn't see it, here's a link to a post I did about using Transfer's metadata to create your own implementation of getMemento(): http://www.silverwareconsulting.com/index.cfm/2008/6/17/Using-Transfer-Metadata-to-Create-a-Memento

I use this utility object to take a Struct of key/value pairs and call
all setters on a given object which have a "setX" method where X is
the name of a key in the Struct.

http://gist.github.com/227407

Used like:

BeanUtil.populateBean(someObject, someStruct);

Might be a little slower due to its usage of cfinvoke versus Evaluate()

/Cody

[achebe]

I just recently ditched cfinvoke for something similar to this:

<cfset var metadata = getTransfer().getTransferMetaData
(getClassName()) />
<cfset var keys = ''/>
<cfset var key = ''/>
<cfset var method = ''/>
<cfset var value = ''/>

<cfset keys = StructKeyList(arguments)/>

<cfloop list="#keys#" index="key">

<cfif StructKeyExists(variables,'set#key#')>

<cfset method = variables['set#key#']/>
<cfset value = arguments[key]>

<cfset method(value)/>

</cfif>

</cfloop>

so instead of using this I use the variables scope and instead of
using cfinvoke I just call the function directly.
It seems to perform better but I'm not 100% sure it's thread safe
yet...

With your code Bob (I had to piece it together from your site, so I'm
posting the basic decorator here) I simply created
abstractDecorator.cfc:

[i],varValue,arguments.Overwrite) />
<cfcatch type="any"></cfcatch>
</cftry>
</cfloop>
</cfif>
</cffunction>

</cfcomponent>

I then had my regular decorators for each object (such as
components.decorators.post for my "posts.post" Transfer object) extend
this abstractDecorator, so:

<cfcomponent displayname="post" output="false"
extends="components.decorators.abstractDecorator">
<cfproperty name="postID" type="numeric" default="" />
<cfproperty name="postTitle" type="string" default="" />
</cfcomponent>

Now I can simply do:

post1 = instance.Transfer.get("posts.post", rc.postID);
post2 = instance.Transfer.new("posts.post");
tempTO = structNew();
post1.copyToStruct(tempTO);
post2.populate(tempTO);
instance.Transfer.save(post2);

This effectively makes a copy of post1 to post2 and saves it.

Excellent work Bob and thank you!
