        Coming soon: Generate parent-child objects

        written 4815 days ago

        A couple weeks ago, we announced that POG 2.0 will allow medium-advanced programmers to generate POG objects programmatically through a SOAP web-service.

        There’s also a 2nd important feature which has been implemented in POG 2.0 and we’d like to talk about it in this post: Generation of parent(s)-child(ren) objects. This has been a much demanded feature for a while now, and we’re very happy to finally provide a solution.

        As usual, our focus has been to implement the cleanest, simplest and most elegant solution possible and this is what it boils down to:

        Preserving POG’s simplicity
        One of POG’s core strengths is its simplicity and almost-zero learning curve. And the reason behind this simplicity is that generated objects only have 5 essential CRUD methods: Save, SaveNew, Delete, Get and GetList.

        POG 2.0 preserves this simplicity by generating parent-child code only when it is requested. That is, if you choose not to “connect” your objects upon generation, the objects generated in POG 2.0 will be exactly identical to POG 1.6 or any other prior version.

        Moreover, when objects are connected, POG generates the minimum amount of code possible to keep your objects small and easy to maintain:

        Parent – Child relationships
        POG 2.0 allows you to generate objects that are related to other objects. We’ve added 2 new attribute types which can be assigned to your object attributes: Child and Parent.

        Let’s say you intend to generate 2 objects: Author and Book. When you’re defining the Author object, simply add ‘Book’ as one of its attributes and assign the attribute type ‘Child’ to it. This tells POG that Author is a parent object and will be connected to a Book object. Next, while defining the Book object, add ‘Author’ as one of the attributes and assign the attribute type ‘Parent’ to it.
        You’ve essentially connected two objects. Pretty simple, no?

        The assumption here is that the developer is responsible for generating the correct relations because we wanted POG to remain stateless and didn’t want to over-complicate the UI. So for instance, if a developer generates an Author object and assigns a Book object as child, then he/she needs to generate a Book object and assign Author as parent. POG does not enforce any rules upon generation and will not tell the developer what he/she needs to do.

        So, what does the developer get at the end of all this? The added benefits of generating code relations is that POG generates additional helper methods that accelerate web development even more. The following is a summary of the exact benefits:

        Parent Object
        The developer can simply call Object -> Save() and all the children associated with that object will be saved recursively.

        Allows recursive deletion of children objects. For example, calling Delete(deep) on an Author object will also delete all the Book objects associated with that author from the database.

        Associates a child object to the parent object.

        Retrieves all children associated with parent object.

        Child Object
        Associates a parent object to the child object

        Returns the parent object associated with the child object

        Note that a developer can very well manually implement relations between objects and could implement the same type of functions. As with the 5 essential CRUD methods, POG simply generates the above list of Relations function to accelerate development even more.

        We’ll soon create We’ve created a PDF document which explains how to use the Relations functions along with code samples and we’ll add added it to our tutorials section

        POG 2.0 will be released around April 1st 2006. In the meantime, you can find a preview at http://beta.phpobjectgenerator.com

        u should put this thing in tutorial part in the front.
