Re: How to handle hasMany data entry
You can place some fields that are actually not in the model in the
validate array. The problem with your case, it that you do not have a
definite limit.
There is an option you can set in the $validate .. 'on' => 'create'
and 'on' => 'update' associated with the array (same level as 'rule').
I have seen it in the code of validation.php in the cake1.2 branch and
it relies on the definition of $id in the $this->data of the
Model ..maybe it's on way (but really never tried it)...

Re: How to handle hasMany data entry
Thanks for the advice. Unfortunately this will not work for me
because it chokes on:
$this->Mark->invalidate('mark_number'.$i, "Mark already exists);
I have two types of marks for input (NewMarks and ExistingMarks), and
they are stored in the data matrix under $this->data['NewMarks'] not
under $this->data['Marks'].
So with the above statement, cake tries to look for the variable
data['Marks'] and invalidate it and I get the error message
Undefined property: ObservationsController::$Mark [CORE\app
\controllers\observations_controller.php, line 134]
Is there any way to invalidate a field directly in the controller if
the field is not attached to any model field?
For example, is there anyway to access the form helper directly in the
controller a.la.
$this->form->error('NewMarks'.'mark_number'.$i, "Mark already
exists" );
The above won't work, but you get the idea. By the way, I am using
the formHelper and validation from 1.2

Re: How to handle hasMany data entry
What you could possibly do (maybe it's not the best), is to loop on
the single validation of the model by setting your different field
value to it :
In controller:
$this->Mark->validate = array('mark_number' => your validation); //
this is required if you have other validations in the Mark model (to
eventually process other validation before)
$fail = false;
for($i = 0; i < $nbmark; $i++)
{
$this->Mark->data['Mark']['mark_number'] = $this->data['Mark']
['mark_number'.$i];
if(!$this->Mark->validates())
{
$fail = true;
$this->Mark->invalidate('mark_number'.$i, "Mark already exists);
}
}
if(fail)
{
$this->render(..)
exit();
}
hope this helps

How to handle hasMany data entry
I have the following setup: Class Observation hasMany Marks. The Marks Class only has one relevant field: mark_number I am working on the add form for my Observations, and the problem is that I do not know in advance how many Marks a given observation will have. I initialize the form with one mark field called data['Marks'] ['mark_number0'], and then if the user has multiple marks he can click on a "add another mark" link which dynamically creates a new field data['Marks']['mark_number1'] and so on. So far so good. My problem comes to dealing with data validation. First, I need to check that each mark_number is unique and doesn't already exist in the database and if not I need to invalidate the field. I would like to put the validation routine inside my Mark model, but it only has a single field mark_number, and not mark_number0, etc, so I cannot invalidate the appropriate field there. I can code all of this by hand, but it is ugly and feels wrong as if I am not taking advantage of all the cakey goodness. What is the best practice way to deal with this situation.
