ActiveRecord attribute value cannot be overwritten

Question

I'm working with Yii. In my controller I use the following code to update my model attribute values with my POST input values:

$foo->attributes = $_POST['Foo'][$i];

This overrides all my attributes, except one. I cannot figure out why it won't override that single one.

Table structure:

price (decimal 11,2)
amount (int 11)
period (varchar 255)

I cannot override the amount field, not even manually. Is it because of it being an int? I haven't had issues with int before though.

I have used var_dump() to check the contents of both $foo->attributes and $_POST['Foo'][$i] and they are correct and all filled in. It just won't override the amount in $foo->attributes.

Validation rules

array('period, price', 'required'),
array('amount', 'numerical', 'integerOnly'=>true),
array('period', 'length', 'max'=>255),
array('price, amount', 'length', 'max'=>10),
array('amount, period, price', 'safe', 'on'=>'search')

amount should always be an integer. Testing values were 10, 20, 30.

Example of issue

var_dump( $foo->attributes );
var_dump( $_POST['Foo'][$i] );
$foo->attributes = $_POST['Foo'][$i];
var_dump( $foo->attributes );

Outputs the following:

//$foo->attributes 
array (size=3)
  'price' => string '140.00' (length=6)
  'amount' => string '10' (length=2)
  'period' => string 'monthly' (length=6)

//$_POST['Foo'][$i]
array (size=3)
  'price' => string '150.00' (length=6)
  'amount' => string '20' (length=2)
  'period' => string 'yearly' (length=6)

//$foo->attributes after rebinding
array (size=3)
  'price' => string '150.00' (length=6)
  'amount' => string '10' (length=2)
  'period' => string 'yearly' (length=6)

There are some additional fields in there. For example the model has a few more fields that the $_POST array doesn't have, but they seem to merge nicely. Should I add these too or are they irrelevant?

Answer 1

Temporary solution

In the end I used the following (temporary) solution, but it is very odd that I actually need to set the value twice before it works:

$foo->attributes = $_POST['Foo'][$i];
$foo->amount = $_POST['Foo'][$i]['amount'];

Answer 2

check for your rules first for your scenario!

I suppose by attributes you mean one of your price amount period attributes, right. you can do like:

$foo->setAttributes(array(
    'price' => $_POST['Foo']['price'],
    'period' => $_POST['Foo']['period'],
    'amount' => $_POST['Foo']['amount'],
));

or simply

$foo->amount = $_POST['Foo']['amount'];

UPDATE: try changing

$foo->attributes = $_POST['Foo'][$i]

to

$foo->setAttributes($_POST['Foo']);

Answer 3

I think you're using validation for fields price, period, but not for amount. You have 2 way:

• use $foo->setAttributes($_POST['Foo'][$i], false) - not recommend
• add amount to validation rules as: array('amount', 'safe'), or better: array('amount', 'numerical', 'integerOnly'=>false),)

OR
You haven't amount in attributes list of the model Foo
