灰烬辛烷值升级如何将值从组件传递到控制器 [英] Ember Octane Upgrade How to pass values from component to controller
问题描述
从灰烬<3.15升级到>=3.15.如何将表单值从控制器传递到组件中?
Upgrade from Ember <3.15 to >=3.15. How do I pass form values from a controller into a component?
我无法开始解释尝试的诊断组合的数量及其收到的相应错误.因此，我想最好问一下应该如何正确完成?闪闪发光是否参与其中?
I cannot begin to explain the number of diagnostic combinations attempted and their corresponding errors received. So, I figure it best to ask how it should be done correctly? Is Glimmer involved?
一个简单的示例:通过组件将更改密码从 old密码传递到到 和confirm密码.在组件中，我不断收到onsubmit() is not a function错误.
A simple example: pass a change password from old password to both a new and confirm password via a component to a controller. In the Component, I keep getting onsubmit() is not a function error.
代码示例:
用户输入表格
ChangePasswordForm.hbs
<div class="middle-box text-center loginscreen animated fadeInDown">
<div>
<h3>Change Password</h3>
<form class="m-t" role="form" {{on "submit" this.changePassword}}>
{{#each errors as |error|}}
<div class="error-alert">{{error.detail}}</div>
{{/each}}
<div class="form-group">
{{input type="password" class="form-control" placeholder="Old Password" value=oldPassword required="true"}}
</div>
<div class="form-group">
{{input type="password" class="form-control" placeholder="New Password" value=newPassword required="true"}}
</div>
<div class="form-group">
{{input type="password" class="form-control" placeholder="Confirm Password" value=confirmPassword required="true"}}
</div>
<div>
<button type="submit" class="btn btn-primary block full-width m-b">Submit</button>
</div>
</form>
</div>
</div>
模板组件
ChangePassword.hbs
<Clients::ChangePasswordForm @chgpwd={{this.model}} {{on "submit" this.changePassword}} @errors={{this.errors}} />
组件
ChangePasswordForm.js
import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';
import { action } from '@ember/object';
export default class ChangePasswordForm extends Component {
@tracked oldPassword;
@tracked newPassword;
@tracked confirmPassword;
@tracked errors = [];
@action
changePassword(ev) {
// Prevent the form's default action.
ev.preventDefault();
this.oldPassword = ev.oldPassword;
this.newPassword = ev.newPassword;
this.confirmPassword = ev.confirmPassword;
// Call the form's onsubmit method and pass in the component's values.
this.onsubmit({
oldPassword: this.oldPassword,
newPassword: this.newPassword,
confirmPassword: this.confirmPassword
});
}
}
控制器
ChangePassword.js
import Controller from '@ember/controller';
import { inject as service } from '@ember/service';
import { action } from '@ember/object';
export default class ChangePassword extends Controller {
@service ajax
@service session
@action
changePassword(attrs) {
if(attrs.newPassword == attrs.oldPassword)
{
this.set('errors', [{
detail: "The old password and new password are the same. The password was not changed.",
status: 1003,
title: 'Change Password Failed'
}]);
}
else if(attrs.newPassword != attrs.confirmPassword)
{
this.set('errors', [{
detail: "The new password and confirm password must be the same value. The password was not changed.",
status: 1003,
title: 'Change Password Failed'
}]);
}
else
{
let token = this.get('session.data.authenticated.token');
this.ajax.request(this.store.adapterFor('application').get('host') + "/clients/change-password", {
method: 'POST',
data: JSON.stringify({
data: {
attributes: {
"old-password" : attrs.oldPassword,
"new-password" : attrs.newPassword,
"confirm-password" : attrs.confirmPassword
},
type: 'change-passwords'
}
}),
headers: {
'Authorization': `Bearer ${token}`,
'Content-Type': 'application/vnd.api+json',
'Accept': 'application/vnd.api+json'
}
})
.then(() => {
// Transistion to the change-password-success route.
this.transitionToRoute('clients.change-password-success');
})
.catch((ex) => {
// Set the errors property to the errors held in the ex.payload.errors. This will allow the errors to be shown in the UI.
this.set('errors', ex.payload.errors);
});
}
}
}
型号
ChangePassword.js
import Route from '@ember/routing/route';
import AbcAuthenticatedRouteMixin from '../../mixins/abc-authenticated-route-mixin';
export default Route.extend(AbcAuthenticatedRouteMixin, {
//export default class ChangePasswordRoute extends Route(AbcAuthenticatedRouteMixin, {
model() {
return {
oldPassword: '',
newPassword: '',
confirmPassword: ''
};
},
})
推荐答案
@glimmer/component中没有onsubmit方法，因此无法在组件中的操作内部调用this.onsubmit.
There is no onsubmit method in @glimmer/component, so you cannot call this.onsubmit inside an action in the component.
首先，您需要将在控制器中创建的操作传递给组件.可以这样完成:
First, you need to pass the action created in your controller to your component. This can be done like this:
<ChangePasswordForm @chgpwd={{this.model}} @changePassword={{action 'changePassword'}} />
请记住，您无法再在微光组件中传递数据，因为所有操作都是一种绑定方式，所以您需要使用操作.
Remember, you cannot pass data up any more in a glimmer component, you need to use an action since everything is one way binding.
第二，您需要在微光组件内部调用此操作:
Second, you need to call this action inside your glimmer component:
this.args.changePassword({
oldPassword: this.oldPassword,
newPassword: this.newPassword,
confirmPassword: this.confirmPassword
});
I've created an Ember Twiddle for you to show this example working.
