我正在尝试使用ember-cp-validations添加表单验证,并遵循控制台中video TypeError: user is null
的基本步骤。我很贪婪,我确信这是我非常基本的东西。
注册表单组件
import Ember from 'ember';
export default Ember.Component.extend({
user: null,
actions: {
save() {
let user = this.get('user');
user.validate()
.then(({ validations }) => {
if (validations.get('isValid')) {
user.save();
} else {
alert("not valid");
}
});
}
}
});
用户模型
import DS from 'ember-data';
import { validator, buildValidations } from 'ember-cp-validations';
const Validations = buildValidations({
firstname: validator('presence', true),
email: [
validator('presence', true),
validator('format', { type: 'email' })
],
username: validator('presence', true),
password: [
validator('presence', true),
validator('length', {
min: 4
})
]
});
export default DS.Model.extend(Validations, {
firstname: DS.attr('string'),
email: DS.attr('string'),
username: DS.attr('stirng'),
password: DS.attr('string')
});

您需要将新用户传递给组件,如下所示:
//routes/users/new.js
...
model(){
return this.get('store').createRecord('user');
}
...
在模板中,您将注册组件放在:
//templates/users/new.hbs
{{register-form user=model}}
