    @staticmethod

    def insert_roles():

    roles = {

    'User': (Permission.FOLLOW |

    Permission.COMMENT |

    Permission.WRITE_ARTICLES, True),

    'Moderator': (Permission.FOLLOW |

    Permission.COMMENT |

    Permission.WRITE_ARTICLES |

    Permission.MODERATE_COMMENTS, False),

    'Administrator': (0xff, False)

    }

    for r in roles:

    role = Role.query.filter_by(name=r).first() if role is None:

    role = Role(name=r)

    role.permissions = roles[r][0]

    role.default = roles[r][1]

    db.session.add(role)

    db.session.commit()

    请问roles字典中Permission.FOLLOW |Permission.COMMENT |

    Permission.WRITE_ARTICLES, True

    这里的|代表什么意思啊 是表示换行吗?

    $this 的含义表示什么,实例化后的具体对象!

    我们一般是先声明一个类,然后用这个类去实例化对象!

    但是,当我们在声明这个类的时候,想在类本身内部使用本类的属性或者方法。应该怎么表示呢?

    例如:

    我们声明一个User类!它只含有一个属性$name;

    classname

    {

    public $_name;

    }

    现在我们给User类加个方法。使用getName()方法,输出$name属性的值吧!复制php内容到剪贴板

    php代码:

    class User

    {

    public $name;

    function getName()

    {

    echo $this->name;

    }

    }

    //如何使用呢?

    $user1=new User();

    $user1->name='张三';

    $user1->getName();

    $user2=new User();

    $user2->name='李四';

    $user2-getName();

    怎么理解呢?

    我上面创建了两个User对象。分别是$user1和$user2.

    当我调用$user1->getName()的时候。上面User类中的代码echo $this->name ;就是相当于是echo $user1->name;

    大概就是这个意思!

    其实,你也不要去钻牛角尖。你只要知道那是一个用来表示类内部的属性和方法的代号就好了!越想越糊涂的!
