Prevent admin edit of responses was created by ChristianSpartacus
I need to be able to configure an anonymous token-based closed survey so that the admin does not have the ability to edit responses through the admin UI.

Any other tips to help respondents be reasonably assured that there is not an easy way for someone to change their answers are welcome.

Thank you in advance!

Why not keeping the superadmin user for your own and giving the admin a user with limited permissions?

If not, you can always edit the source code to disable the editing.

Thank you!

Do you happen to know which source code file I would edit to prevent even the superadmin from having access to edit responses?

This is a hack to entirely disable response editing. It needs to be tested and will be over-written on updates.

In /application/models/Permission.php, find this function:
Code:
    function hasSurveyPermission($iSurveyID,$sPermission, $sCRUD, $iUserID=null)
    {
        $oSurvey=Survey::Model()->findByPk($iSurveyID);
        if (!$oSurvey) 
            return false;
        $iUserID=self::getUserId($iUserID);
        if(!$iUserID)
            return false;
        // If you own a survey you have access to the whole survey
        if ($iUserID==$oSurvey->owner_id) 
            return true;
 
        // Get global correspondance for surveys rigth
        $sGlobalCRUD=($sCRUD=='create' || ($sCRUD=='delete' && $sPermission!='survey') ) ? 'update' : $sCRUD;
 
        return $this->hasGlobalPermission('surveys', $sGlobalCRUD, $iUserID) || $this->hasPermission($iSurveyID, 'survey', $sPermission, $sCRUD, $iUserID);
    }
And replace it with this:
Code:
    function hasSurveyPermission($iSurveyID,$sPermission, $sCRUD, $iUserID=null)
    {
        $oSurvey=Survey::Model()->findByPk($iSurveyID);
        if (!$oSurvey) 
            return false;
        $iUserID=self::getUserId($iUserID);
        if(!$iUserID)
            return false;
        // Entirely disable editing responses
        if($sPermission == 'responses' && ($sCRUD == 'create' || $sCRUD == 'update' || $sCRUD == 'delete'))
            return false;
        // If you own a survey you have access to the whole survey
        if ($iUserID==$oSurvey->owner_id) 
            return true;
 
        // Get global correspondance for surveys rigth
        $sGlobalCRUD=($sCRUD=='create' || ($sCRUD=='delete' && $sPermission!='survey') ) ? 'update' : $sCRUD;
 
        return $this->hasGlobalPermission('surveys', $sGlobalCRUD, $iUserID) || $this->hasPermission($iSurveyID, 'survey', $sPermission, $sCRUD, $iUserID);
    }
Cheers,
