Question

在我的个人资料模型中，我有这个方法：

// Check login and return object
checkLogin: function(username, password) {
        ProfileObj = Profile.find({username: username, password: password}).one(function(err, profile){
                         return profile;
                    });

        console.log(ProfileObj);
        return ProfileObj;
}

要调用此方法，我使用：

profile = req.models.profile();
ProfileObj = profile.checkLogin('test', 'test');

不幸的是，我没有得到我想要的对象，我得到的是模型，而不是实例。 find（）回调中的“profile”var是我想要的，但不会返回。相反，ProfileObj是整个模型。

您能否告诉我如何正确返回find（）回调中的“个人资料”。

由于node.js使用异步代码，因此无法实现。

您可以在模型中创建一个方法，如下所示：

<form onSubmit={this.stopSubmit}>
                        <FormGroup
                            controlId="formBasicText"
                            validationState={getValidationState()}
                        >
                            <ControlLabel>Stuff</ControlLabel>
                            <FormControl
                                type="text"
                                value={this.state.value}
                                placeholder="Enter text"
                                onChange={handleChange}
                                onKeyUp={handleSubmit.bind(this, "test")}

                            />
                            <FormControl.Feedback/>
                            <HelpBlock>Validation is based on string length.</HelpBlock>
                        </FormGroup>
                    </form>

由于理论上您提供了表单提交中的用户名和密码，因此您可以执行以下操作：

models.profile = db.define('profile', {
    id: { type: 'serial', key: true },
    another_column: { type: 'text' }
}, {
   methods: {
       checkLogin: function (username, password) {
           models.profile.one({ username, password }, (err, user) => {
               return user;
           });
       }
    }
}

祝你好运！
