[transfer-dev] Re: Soft Delete?
Rob,
I currently handle soft deletes (when required) using a delete() method on
my TO decorator. Say I have a an e-commerce catalog with categories and
items and categories are recursive. If a category has related items or
sub-categories, I want to soft delete. Here's the method to handle that:
cffunction name=delete hint=Delete the current instance
returntype=void output=false access=public
cfscript
if (isParent() || hasItem()) {
// enact soft delete
setIsDeleted(true);
getCatalogDao().save(this);
} else {
getCatalogDao().delete(this);
}
/cfscript
/cffunction
In my service, I would then use something along the line of.
cffunction name=deleteCategory returntype=void output=false
access=public
cfargument name=CategoryId type=numeric required=true
cfscript
var category = getCategory(arguments.CategoryId);
category.delete();
/cfscript
/cffunction
I prefer this approach since it encapsulates the delete logic in the
business object.

Hi John, thanks.
Yeah the way I see its implementation working would be to keep the
delete method invoketion the same, just change its implementation
dependant on the XML configuration, this would allow some objects to
be properly deleted and other only soft deleted likewise with
cascading the deletes, sometimes I'll want a parent object to be soft
deleted but its children are not audited so they can be properly
removed :-)
I kind of remember someone mentioning it was on the roadmap when I
last asked a few months back, perhaps I'll play around with some
patches and suggestions for Mark and see if I cant accelerate it a
little.

[transfer-dev] Re: Decorator Dependancy Injection
With Brian's blessing, I incorporated the BeanInjector into Metro and use it within the Service and Transient Factories therein. To enable injection of transient objects into a TO Decorator, I create a setter in the Decorator for the TransientFactory. The TO then asks the factory for a transient when required. A validator instance for example. Here's a snippet from the metro core (base) decorator. cffunction name=setTransientFactory access=public returntype=void output=false cfargument name=TransientFactory type=metro.factory.TransientFactory required=true cfset variables.TransientFactory = arguments.TransientFactory /cffunction cffunction name=getTransientFactory access=public returntype=metro.factory.TransientFactory output=false cfreturn variables.TransientFactory / /cffunction cffunction name=setValidator access=public output=false returntype=void hint=I set a reference to the generic Validator. cfargument name=Validator type=any required=false hint=The Validator. cfif (not structkeyExists(arguments,Validator)) cfset arguments.Validator = getTransientFactory().create(Validator) /cfif cfset variables.properties.Validator = arguments.Validator /cffunction cffunction name=getValidator access=public output=false returntype=any hint=I return the generic Validator. cfif (not structkeyExists(variables.properties,Validator)) cfset setValidator() /cfif cfreturn variables.properties.Validator /cffunction HTH On Mon, Mar 2, 2009 at 9:58 AM, Brian Kotek brian...@gmail.com wrote: The Bean Injector isn't meant to be used directly with beans managed by ColdSpring.

It does indeed cache the dependencies, which means you'll get the same ColdSpring beans wired into each instance. Otherwise it would have to resolve the dependencies for every instance, which would be a big performance hit. So to be clear, it's meant to wire Singleton beans into transient objects. It isn't meant to wire multiple transients together, that's getting into ORM territory.

[transfer-dev] Re: Saving the Secondary Key on a ManyToOne value?
Matthew, Transfer does not generate methods to create compositions based on your FK names. Therefore, if you wish to use that convention, you must use a decorator and and behaviour to your BO. You have two choices. 1. objGallery = transfer.getTransfer().new(Gallery); objProduct = transfer.getTransfer().get(Product,form.Id);objGallery.setTestField(cat); objGallery.setProduct(objProduct); transfer.getTransfer().save(objGallery); 2. Add a method to your Gallery Decorator cffunction name=setProductId returntype=void output=false access=public cfargument name=ProductId required=yes type=numeric / cfset var product = getTransfer().get(Product,arguments.ProductId) cfset getTransferObject().setProduct(product) / /cffunction If you go with option 2, I'd recommend a get method that returns the productId. Why does it work this way? Tranfer ORM is an object relational mapper, so one should make every effort to augment their thinking for table relations to object relations. It's not easy. I had a difficult time making the adjustment. Best of luck!

Stephen, Out of curiosity, are both applications being initialized with the same transfer.xml and use the same definitions path? If so, then targeting the server scope for cache is the way to go.

If I dump the object I see all the methods that are automatically created for me via transfer - so far so good and I can see the methods for setting / getting the fields I have declared in my XML. Specifically I see a method setisuetype issue type is a manytoone with the following declaration in my XML; object name=issueType table=tbl_issueType id name=id_tbl_issueType type=numeric / property name=issueType type=string / /object object name=generalCAR table=tbl_CAR manytoone name=issueType link to=car.issueType column=issueTypeId / /manytoone ... /object Now if I have the following in my form's action page; cfset session.generalCAR.setissueType(form.issueTypeId) / then I get the following error; The TRANSFER argument passed to the setissueType function is not of type transfer.com.TransferObject. If the component name is specified as a type of this argument, its possible that a definition file for the component cannot be found or is not accessible. Huh? If I dump the session.generalCAR, then the method is there.. I tried by creating an issueType object with the following; session.issueType = application.transfer.new(car.issueType); And then I can successfully do this; cfset session.issueType.setissueType(form.issueTypeId) / But from my previous post(thread) that seems to have goteen a little butchered when Kevin's email client misbehaved I was given the advice that I didn't need to do this and that I should ust use the generalCAR.setissueType method, Have I missed something? mis-understood the replies - or am I just a completely mad nutter! -- Hey!

[transfer-dev] Re: Self-Referencing onetomany relationship breaking on save
Hi John, I played with this from a onetomany prespective and quickly learned that I had an object explosion on my hands since each object would maintain a reference to it's parent and a collection of child objects. Instead, I modeled it with simplicity and performance in mind. With manytoone, the child object will have a hasParent() method and I can get the full path to the top level parent object using recursion. Here's an example method for retrieving a path to the root from any self-referencing (transfer) object with manytoone relationship (assuming the object has a getName() method). cffunction name=getTreePath access=public output=false returntype=string cfargument name=obj type=any required=true cfargument name=path type=string required=false default= cfset var treePath = / arguments.obj.getName() arguments.path cfif arguments.obj.hasParent() cfset treePath = getTreePath(obj=arguments.obj.getParent(),path=treePath) /cfif cfreturn treePath /cffunction I use something similar for a home grown cms that has parent/child pages. Using mod_rewrite I create SES friendly urls based on the page names. So, you could very easily build a breadcrumb trail in this manner, or with a little sql, create a nested nav of categories. Here's a link to a page on the site I mentioned above. http://www.slcc.ca/about-us/tale-of-two-nations/protocol-agreement Cheers, Paul On Wed, Oct 15, 2008 at 10:19 AM, John Barlow [EMAIL PROTECTED] wrote: I see how that could work, but wouldn't that also remove all of the handy child functions that the onetomany relationship would give you? On Oct 15, 12:31 pm, Paul Marcotte [EMAIL PROTECTED] wrote: Hi John, I would suggest using a manytoone for nesting categories. The object definition for your category would include manytoone name=Parent lazy=true link to=Category column=category_parent_id/ /manytoone Note that if you use a table column for an object relationship, you cannot have a property referencing the same column. I'm guessing that is why your sql has two references to category_parent_id. Cheers, Paul On Wed, Oct 15, 2008 at 7:32 AM, John Barlow [EMAIL PROTECTED] wrote: Greetings all, I've been racking my brain for about two days to try to figure this out. I have a category table, consisting of, among other things, a category_id and a category_parent_id. The idea is that categories can be sub categories of others (hence the category_parent_id) and have a null parent if they are the root node. I set up a onetomany relationship linking the category_id to the parent_id with lazy loading and everything was working beautifully for reading. The problem cropped up when I tried to save a record. The error that came back was a SQL error, stating category_parent_id appears more than once in the result column list. From what I can find, this error occurs if you have two tables and have the relationship defined on both tables. The solution there is to remove a relationship definition from one of the tables and all is well. Since this is referencing itself, it is inherently getting both sides of the definition defined, which I think is what is causing this to break. I checked the SQL, and indeed it is taking on an extra category_parent_id to the end of the insert statement. I'm not sure if this is a Transfer bug or if I'm trying to use it in a way it wasn't meant to, but having a self-referencing table like this seems like a reasonable thing one would want to be able to model. For the record, I did get around it by using a link table that has two columns that point to the category_id field in the category table and a Many to Many relationship. Ideally, I'd like to not use an extra table to do this. I just wanted to bring this to the masses because I couldn't find anything on this and felt it may have been overlooked. What I WAS able to find was in reference to hibernate.
