Hi Mariano,
Ok, I have extracted the functionality you need in QC-Magritte-Ajax. It
contains a custom renderer to override the table renderer
(QCAjaxTableRenderer). Note that it re-renders the entire table on each
change … so it does not need groups. Unfortunately it does not keep the
focus, this is the only thing that bugs me, and rendering more of the page,
gives a bigger chance of giving the user some annoyance over this.
The package QC-Magritte-Ajax should work stand alone, I did not test this
yet.
Hi Diego, thanks for doing that! A quick tests shows me that it works! The
only small detail is that
QCAjaxMemento #procesHiddenFor: aDescription value: anObject sends
#hiddenValues to the description and #readUsing: sends #isWrapped. We
don't have either of them.
So I think we either move those 2 to QC-Magritte-Ajax or we put a
dependency to QC-Magritte-Other (and hence also QC-Magritte-Core). Maybe
the first option is easier.
In my particular use-case, I usually have many combos lists in which the
"options and values" comes from a DB query. Even if I do have caches etc I
would try to avoid doing such a queries each time a field is modified. So I
will see if I can adapt QCAjaxTableRenderer to perform the ajax only for
groups (as it was the previous render). I think that having ALSO such
feature also in QCAjaxTableRenderer would be awesome. Then we can have
simple flags to update all fields or update only by groups :)
Thanks Diego, it is good to see Magritte-Seaside moving forward!
Cheers,
Diego

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
