We have a plugin (let’s name it “Cms”). This plugin has a model called
Image, used to add images to a model. The Image model is inside the
plugin; others models are, of course, outside (for example the “Page”
model). The relationship is made on the fly, with a code like this
$this->Page->bindModel(array('hasMany' => array('Cms.Image' => array
('foreignKey' => 'record_id'))));
We use Cms.Image because the bind must be donde like: Plugin.Model
Then we want to add a new page, so we write this code in the “add”
view
echo $form->create(array('type' => 'file'));
echo $form->input('Page.title');
echo $form->input('Page.content');
...etc
And now, here is the problem: ¿How do we write the input for the
Image?
If the Image model where outside the plugin, we would normally use:
echo $form->input('Image.0.name');
then in the controller we use the method saveAll, and everything is
smooth.
But the situation is different here, we have a model outside the
plugin (Page) which is associated with a model Inside the plugin
(Image)
My first attempt was to do this:
echo $form->input('Cms.Image.0.name');
but it fails! It generates an input with the attribute name="data[Cms]
[Image][0][name]"
If I hardcode the input field with something like name="data[Cms.Image]
[0][name]" everything works perfect (with validation and callbacks for
both models). But working in this way I have to do an extra job for
display error messages and I assume I would have some other issues if
I don’t use the form helper.
The second idea was:
echo $form->input('Image.0.name', array('plugin' => 'Cms'));
But it didn’t work either, because the input method in the form helper
doesn’t expect a plugin key in the options array and just ignore it. I
read the code of Form::input() and I found that the separation into
array keys by the point is made by a very parent classes, so I neither
could easily hack the core to find a solution.
What do yo think? Is there a way to solve this issue or the problem is
me misunderstanding something? (or everything maybe)
Thanks for the support!
