Hi all,

As you probably all know I have made a library (QC Magritte) that is build on top of Magritte. I think it contains a lot of good add ons, maybe not structured enough. I am trying to clean this code up, so it can be used easily by all. At this point I want to move 2 things to Magritte. One as a change, and one as an add-on:

Change:
I would like to modify the basic MAContainerComponent to cache the description and pre-process this with the description builders. I believe this is a missing hook in Magritte. It is easy to add, and you do not notice it, if you do not use it. Also it applies to all platforms, not just to Seaside, so if you think this is a good idea, I will also modify the glamour container. The following problems can be solved using builders:
- separating display from the model. Now you have to set your custom component classes in the model. It is much more elegant to do this from the display side. To add a builder it can set the component class for each type of description (using visitors), for the application you want to show.
- adding security. When you pre process the description before showing it, you can set fields to readonly, or remove them entirely from the description if the user is not allowed to see those properties.

Add-On:
I would ilke to add a package to Magritte3-AddOns called Magritte-Ajax. In this add-on I will put the things that allow Ajax rendering of the components. Of course this is on top of seaside and only valid for seaside, but that is why I think it should be an add-on and not in the core. This would be:
- The AjaxMemento. (QCAjaxMemento)
- the extension methods for Ajax rendering.
- the extension methods for the added Ajax properties.

All these for sure!

- A renderer, that renders the component, using Ajax. (QCGroupedFormRenderer)

Please let me know if you think this is a good idea. If you know a better place to do these things, or to put the code, let me know.

Hi Diego,

First, thanks for pushing this stuff. I also have many extensions I did myself to Magritte and so far I have them as subclasses or extension methods etc. I need to clean them up before asking if they are useful. I will send a separate mail for that.

For this particular email, I think that what you suggest makes sense. Magritte-Ajax will depend on JQuery right?

I should have answered this email instead of the other one...anyway, I will repeat it here. I would love if the first 3 points of the add on could be used WITHOUT the QCGroupedFormRenderer. Or at least a class that doesn't imply many changes. In other words...to plug that nice behavior with the default rendered class: MATableRenderer.

would that be possible?

Thanks in advance,

If people have questions about QC-Magritte, please do not hesitate to ask them. I will try to respond them fast and I will be available on Skype and Google Hangouts.

Cheers,
Diego
