配置

Backend = Laravel 5.1，使用Dingo API
前端= Ember 1.13.6，Ember Data 1.13.7
适配器= Ember Data RESTAdapter

问题

我试图在我的第一个Ember应用程序上处理后端验证错误。当从服务器返回错误时，我收到此错误：

Error: The adapter rejected the commit because it was invalid
at new Error (native)
at Error.EmberError (http://localhost:4200/assets/vendor.js:26266:21)
at Error.ember$data$lib$adapters$errors$$AdapterError (http://localhost:4200/assets/vendor.js:69564:50)

at XMLHttpRequest.jQuery.ajaxTransport.options.send.callback (http://localhost:4200/assets/vendor.js:9920:8)

来自后端的响应有一个422 Unprocessable Entity标头，内容为：

{
     "message":"Couldn't save client",
     "errors":{
          "name":["The name field is required."],
          "email":["The email field is required."]
      },
     "status_code":422
}

尝试（和失败）解决方案

Ember data Rest adapter error handling not working
扩展RESTAdapter以覆盖ajaxError函数，我现在看起来像这样：

ajaxError: function(jqXHR) {
var error = this._super(jqXHR);
if (jqXHR && jqXHR.status === 422) {
    var jsonErrors = Ember.$.parseJSON(jqXHR.responseText).errors;
    return new DS.InvalidError(jsonErrors);
} else {
    return error;
}
}

向save方法添加catch语句，我的保存操作当前是：

 save() {
    var self = this;

    function transitionToPost(post) {
        self.transitionToRoute('clients.show', post);
    }

    function failure(reason) {
        // handle the error
        console.log(reason);
        return false;
    }

    this.get('model').save().then(transitionToPost, failure).catch(failure);
}

测试出ActiveModelAdapter - 不确定我期望用这个实现什么，但我绝望了;结果仍然相同。
Ember Docs（http://guides.emberjs.com/v1.13.0/models/creating-updating-and-deleting-records/#toc_promises）
正如您在上面的控制器代码中看到的，我实际上将其用作基础

请你看看并提出建议吗？在此先感谢您的帮助！

我的app/adapters/application.js：

export default DS.RESTAdapter.extend({
  ajaxError(jqXHR) {
    var error, errors, jsonErrors, response;
    error = this._super(jqXHR);

    if (jqXHR && jqXHR.status === 422) {
      response = Ember.$.parseJSON(jqXHR.responseText);
      errors = {};
      if (response.errors != null) {
        jsonErrors = response.errors;
        Ember.keys(jsonErrors).forEach(function(key) {
          return errors[Ember.String.camelize(key)] = jsonErrors[key];
        });
      }
      return new DS.InvalidError(errors);
    } else {
      return error;
    }
  }
});

结合模型的自定义ServerErrorsMixin：

export default Ember.Mixin.create({
  isntValid: Ember.computed.not('isValid').readOnly(),

  adapterDidInvalidate(errors) {
    let recordErrors = this.get('errors'),
        hasProp = {}.hasOwnProperty;

    for (let key in errors) {
      if (!hasProp.call(errors, key)) {
        continue;
      }

      let propertyErrors = errors[key];

      if(key === 'duplicate') {
        if(!Ember.isArray(propertyErrors)) {
          recordErrors
          .get('messages')
          .pushObject(propertyErrors);
        } else {
          Ember.debug('It shouldnt be an array.');
        }
      } else {
        for (let e of propertyErrors) {
          recordErrors
          .get(key)
          .pushObject(e);
        }
      }
    }

    this._saveWasRejected();
  }
});

在Ember Data 1.0.0-beta.18中正常工作。如果您尝试这样做，请记住从模型中的ServerErrorsMixin扩展：

import ServerErrorsMixin from '../mixins/server-errors';

export default DS.Model.extend(ServerErrorsMixin, {
  // ...
})

使用RESTAdapter的后端验证始终＆＃34;适配器拒绝提交，因为它无效＆＃34;
