Question

YII框架上有一个工作站点。它应该被添加到一个新的领域。我在数据库表中添加了一列，在模型类中添加了字段和方法的规则，在视图中添加了字段。但是在此字段中输入的数据不会存储在数据库中。怎么解决？其他字段存储正确。

Answer 1

防止此类error是一种好习惯。每当您在field创建table之后添加任何Model时，只需在attribute safe rules()规则的function规则中添加Model.php。

在public function rules() { return array( // all other rules array('newattribute', 'safe'), ); }

    function do_tests(func) {

    if (typeof func !== 'function') return true;
    switch (typeof func.tests) {

            for (var k in func.tests) {

                var test = func.tests[k];
                if (typeof test==='function') {
                    var result = test(func);
                    if (result===false) {
                        console.log(test.name,'for',func.name,'failed');
                        return false;
