Question

我试图使用余烬验证。我在我的控制器中添加了validation.mixin，但它会导致错误。这是我的控制器代码：

var loanController = Ember.ObjectController.extend(Ember.Validations.Mixin);
loanController.reopen({

borrowingLimits:null,
industries:null,
actions:{
submitAction:function(){
var model=this.get('model');
if (model!=null) {
var controller = this;
$.ajax({
type :'post',
async:false,
url : '/api/v1/loanapplication/',
data: JSON.stringify(model),
contentType: "application/json; charset=utf-8"
}).done(function (data) {
controller.transitionToRoute('upload-documents',data);
});
}

}
}, 
validations: {
applicantFirstName: {
presence: true,
length: { minimum: 5 }
}
}
});

export default loanController;

我该如何解决这个问题？

更新我添加了进口

app.import('vendor/ember-validations/packages/ember-validations/lib/core.js');
app.import('vendor/ember-validations/packages/ember-validations/lib/defaultMessages.js');
app.import('vendor/ember-validations/packages/ember-validations/lib/errors.js');
app.import('vendor/ember-validations/packages/ember-validations/lib/main.js');
app.import('vendor/ember-validations/packages/ember-validations/lib/mixin.js');
app.import('vendor/ember-validations/packages/ember-validations/lib/validatorNamespaces.js');
app.import('vendor/ember-validations/packages/ember-validations/lib/validators.js');

Answer 1

您似乎可能错误地导入了ember-validations，但原因的根源是您没有将mixin导入控制器文件。以下将有效。

在Bower.json文件中

{
  "name": "app-name",
  "dependencies": {
    "ember-validations": "http://builds.dockyard.com.s3.amazonaws.com/ember-validations/ember-validations-latest.min.js",
  }
}

运行bower install。

在Brofile.js：

中

app.import('vendor/ember-validations/index.js');

mixins/form-saving.js：

export default Em.Mixin.create(
  Em.Validations.Mixin, {

  // Your common form saving functions and properties
});

controllers/loan.js：

import FormSaving from 'app-name/mixins/form-saving';

export default Em.ObjectController.extend(
  FormSaving, {

  // Methods and Properties here
});

Answer 2

您导入了库吗？

假设您使用的是ember-cli：

// in Brocfile.js after importing ember.js

app.import('vendor/path/to/ember-validations');

TypeError：无法读取未定义的属性“Mixin”
