Symfony2 - How to set the priority of the security voter used by the AccessDecisionManager?

The higher priority listener / voter is executed first.

For listener priorities, the following rules apply:

priority [...] by default is 0.

This value can range from -255 to 255, and the listeners will be executed in order of priority ( highest to lowest ).

(see How to create an event listener. )

app / Config/security.yml

The parameter security.access_decision_manager

determines the strategy used for the final decision:

security:
    access_decision_manager: 
        strategy: affirmative # <- strategy setting

      

        
        
        
      

    

There are 3 strategies available:

• unanimous
  
  - 1 single voter denies access.
• affirmative
  
  - 1 single voter grants access.
• consensus
  
  - The majority wins.

(See Changing Your Decision Making Strategy )

The voter's decision is expressed in the return value of this method vote()

. Example:

use Symfony\Component\Security\Core\Authorization\Voter\VoterInterface;

public function vote(TokenInterface $token, $post, array $attributes)
{
    // ...

    return VoterInterface::ACCESS_GRANTED;
}

      

        
        
        
      

    

• VoterInterface::ACCESS_GRANTED
  
  Permission will be granted by that voter;
• VoterInterface::ACCESS_ABSTAIN
  
  The voter cannot decide whether a permit is permitted;
• VoterInterface::ACCESS_DENIED
  
  The authority will be rejected by that voter.
