FormField for editing has_many relationships
3 February 2012 at 6:02pm
I have a data model that basically boils down to:
- Page has_many Views
- View has_many PageReferences
- PageReference has_one Page and has an integer "Sort"
I've played with a couple of the *ComplexTableField form field options. They are really nice for some things, but not what I need. I need something that will allow management of the "View has_many PageReferences" and "PageReference has_one Page" relationships. At its core, I need something that will:
- List all of the current values contained in a has_many relationship (list all the page references a view has)
- Allow re-ordering of those values (pagereferences in this case)
- Allow deletion of some of the values in the list
- Allow the addition of a new value by a popup (in this case, a popup that would allow you to select a page from your SiteTree)
Of course, that's only the View->PageReference relationship. I'll also need a very similar form control for listing the views a page contains and allowing you to add a new one. But, I think if I can solve the problem above, this secondary problem is so similar that it will be no problem.
I figure that I'll need to create a custom FormField for this. My question is: where should I start? What should it extend? And do you have any documentation on what to do / to avoid when making a FormField?
I've attached a mockup of roughly what I want this tab to look like.

Very cool. Thanks for the tip. I may need to add some ability to order (probably drag and drop with jQuery), but this gets me leaps and bounds towards what I need!

Very welcome!
If you add the drag drop reorder with this I would be eternally grateful if you'd report back with your enhancments

Actually, it looks like it already support sorting:

I haven't tried the sorting yet, but this looks very promising!

so it does!
I'd forgotten that - in that case - if you get a working example please post it asapcouldn't wait
- here is my test for the many many sorting - works great trick is to add a field to the many many relationship...
<?php
class ObjectA extends DataObject {
static $db = array(
'Name' => 'Varchar',
'Description' => 'Varchar(255)',
);static $has_one = array(
'ObjectB' => 'ObjectB'
);static $has_many = array(
'ObjectC' => 'ObjectC'
);static $many_many = array(
'ObjectD' => 'ObjectD'
);static $many_many_extraFields = array(
'ObjectD' => array(
'Sort' => 'Int'
)
);function getCMSFields() {
$fields = parent::getCMSFields();$fields->replaceField('ObjectB',new HasOnePickerField($this,'ObjectB'));
$fields->replaceField('ObjectC',new HasManyPickerField($this,'ObjectC'));
$fields->replaceField('ObjectD',new ManyManyPickerField($this,'ObjectD','',array('Sortable'=>true)));return $fields;
}
}class ObjectB extends DataObject {
static $db = array(
'Name' => 'Varchar',
'Description' => 'Varchar(255)',
);static $has_one = array(
'ObjectA' => 'ObjectA'
);
}class ObjectC extends DataObject {
static $db = array(
'Name' => 'Varchar',
'Description' => 'Varchar(255)',
);
static $has_one = array(
'ObjectA' => 'ObjectA'
);
}class ObjectD extends DataObject {
static $db = array(
'Name' => 'Varchar',
'Description' => 'Varchar(255)',
);static $belongs_many_many = array(
'ObjectA' => 'ObjectA'
);
}
