我试图为我的模型类创建一个通用的编码器和解码器.我试图找到一种方法来为所有类型的属性调用"编码方法",无论是对象(NSString,NSNumber,NSArray等)还是原始类型.我看到有人在做以下事情.我想知道这是否是一种正确的方法.

属性:

@property (assign,nonatomic) int integerP;
@property (assign,nonatomic) float floatP;
@property (assign,nonatomic) BOOL boolP;

Enconder和解码器代码:

- (void)encodeWithCoder:(NSCoder *)encoder
{
    id object2 = [self valueForKey:@"integerP"];
    id object3 = [self valueForKey:@"floatP"];
    id object4 = [self valueForKey:@"boolP"];


    [encoder encodeObject:object2 forKey:@"integerP"];
    [encoder encodeObject:object3 forKey:@"floatP"];
    [encoder encodeObject:object4 forKey:@"boolP"];

    //[self setValue:[NSNumber numberWithInt:90] forKey:@"heightR"];

    //NSLog(@"%@",[self valueForKey:@"heightR"]);


}

- (id)initWithCoder:(NSCoder *)decoder
{
    self = [super init];
    if( self != nil )
    {

        id object2 = [decoder decodeObjectForKey:@"integerP"];
        [self setValue:object2 forKey:@"integerP"];
        id object3 = [decoder decodeObjectForKey:@"floatP"];
        [self …

我在两个偏执表（用户和电子邮件）之间有一个关系，并且该关系上有 onDelete: 'cascade' 选项（ Email.belongsTo(User, onDelete:'cascade') ）。

问题是，当我删除用户时，他的电子邮件不会被级联删除。

是我写错了还是sequelize有bug？

我在postgres数据库上使用sequelize 2.0.0-rc2。

var Sequelize = require('sequelize')
    , sequelize = new Sequelize('test', 'test', 'test', {dialect: 'postgres'});

var User = sequelize.define('User', {
    username: Sequelize.STRING,
    birthday: Sequelize.DATE
}, {paranoid: true}); //Without paranoid the code works fine

var Email = sequelize.define('Email', {
    email: Sequelize.STRING,
    primary: Sequelize.BOOLEAN
}, {paranoid: true}); //Without paranoid the code works fine

Email.belongsTo(User, {onDelete: 'cascade'});

sequelize.sync().success(function () {
    var userCreatedInstance = null;

    var deletedUserId …
