cakephp error: unexpected '(', expecting ')', is my syntax wrong? - syntax

Question

Do you see any syntax errors here?
'Coupon'=>array(
'fields'=>array(
'promo_code','desc'
),
'conditions'=>array(
'OR'=>array(
'expires' =>0,
'Coupon.end_date >'=>date('Y-m-d')
)
)
),
This is part of my 'contain' array in my controller code. When I remove this snippet from my code, cake works great (only I need this part!). Am posting the entire statement below. Help?
public $paginate = array(
'Location'=>array(
'joins' => array(
array(
'table' => 'locations_tags',
'alias' => 'LocationsTag',
'type' => 'inner',
'conditions'=> array(
'LocationsTag.location_id = Location.id'
)
)
),
'limit'=>9,
'contain'=>array(
'Course'=>array(
'fields'=>array(
'specials', 'contact','desc'
),
'conditions'=>array('Course.active'=>1)
),
'Charter'=>array(
'fields'=>array(
'book','specials', 'contact','desc'
),
'conditions'=>array('Charter.active'=>1)
),
'Restaurant'=>array(
'fields'=>array(
'menu','wine_list','specials', 'contact','desc'
),
'conditions'=>array('Restaurant.active'=>1)
),
'Nightclub'=>array(
'fields'=>array(
'menu','schedule','specials', 'contact','desc'
),
'conditions'=>array('Nightclub.active'=>1)
),
'Store'=>array(
'fields'=>array(
'catalog','specials', 'contact','desc'
),
'conditions'=>array('Store.active'=>1)
),
'Coupon'=>array(
'fields'=>array(
'promo_code','desc'
),
'conditions'=>array(
'OR'=>array(
'expires' =>0,
'Coupon.end_date >'=>date('Y-m-d')
)
)
),
'Image',
'Tag'=>array(
'fields'=>array(
'seo_tag'
)
)
)
)
);

'Coupon.end_date >'=>date('Y-m-d')
You can't assign calculated values (e.g., calling functions) in class property declarations. They have to be constant values.
For a calculated value, you'd have to assign that in the constructor or something.
From the docs:
This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.
