我在每一行都有一个表(一个组件)和一个删除按钮。当点击删除按钮时,应该删除特定的行。在Ember中删除一条记录数据不工作
试过以下代码:
MyComponent.js
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
deleteCartRecord(cartDetails){
debugger;
this.sendAction('deleteRecord',cartDetails);
}
}
});
在MyComponent.hbs
{{#each model.orderParts as |newCart|}}
<div class="card-wrapper col-lg-12 col-md-12">
<div class="col-lg-2 col-md-2">
<div class="order-id">{{newCart.partNumber}}</div>
{{#if (gte newCart.promiseQty newCart.quantity)}}
<div class="order-status delivered">{{env.APP.StockAvailable}}</div>
{{else}} {{#if (gt newCart.promiseQty '0'(and (lt newCart.promiseQty newCart.quantity)))}}
<div class="order-status intransit">{{env.APP.LowInStock}}</div>
{{else}} {{#if (eq newCart.promiseQty '0')}}
<div class="order-status outofstock">{{env.APP.OutofStock}}</div>
{{/if}} {{/if}} {{/if}}
</div>
<div class="col-lg-3 col-md-3">
<div class="item-header">Delivery Date</div>
<div class="item-data">{{newCart.deliveryDate}}</div>
</div>
<div class="col-lg-2 col-md-2">
<div class="item-header">Required Qty.</div>
<div class="item-data">
{{increse-required-quantity incresedQuantity=newCart.quantity}}
</div>
</div>
<div class="col-lg-2 col-md-2">
<div class="item-header">Unit Price</div>
<div class="item-data">{{newCart.unitPrice}}</div>
</div>
<div class="col-lg-2 col-md-2">
<div class="item-header">Total Price</div>
<div class="item-data">{{newCart.partTotalPrice}}</div>
</div>
<div class="col-lg-1 col-md-1 button-colum"><button type="button" class="btn btn-danger" {{action "deleteCartRecord" newCart}}>Delete</button> </div>
</div>
{{/each}}
我的控制器
import Ember from 'ember';
export default Ember.Controller.extend({
actions:{
deleteRecord(data){
debugger;
let confirmation = confirm("are you sure to delete");
if(confirmation)
{
debugger;
data.deleteRecord();
data.save();
}
}
}
});
模板文件,其中组分是CA大会另作
<hr>
</div>
<div class="col-lg-12 col-md-12">
<div class="checkout-summery-wrapper">
<div class="total-label">Total</div>
<div class="total">{{model.totalPrice}}</div>
<!--<div class="tax-text">(Inclusive of all taxes)</div>-->
<div class="place-order-button"><button type="button" class="btn siemens-btn">Place Order</button></div>
</div>
</div>
<div class="col-lg-12 col-md-12">
{{#if model.orderParts.isGeneric}}
<div class="panel panel-default card-list-panel">
<div class="panel-heading-cart col-lg-12 col-md-12">
<div class="col-lg-11 col-md-11 heading">Generic Parts</div>
<div class="col-lg-1 col-md-1"><a href='#' class="delete-all">Delete All</a></div>
</div>
<div class="panel-body">
{{cart-record model = model}}
</div>
</div>
{{/if}}
{{#unless model.orderParts.isGeneric}}
<div class="panel panel-default card-list-panel">
<div class="panel-heading-cart col-lg-12 col-md-12">
<div class="col-lg-11 col-md-11 heading">Hot Gas Path</div>
<div class="col-lg-1 col-md-1"><a href='#' class="delete-all">Delete All</a></div>
</div>
<div class="panel-body">
{{cart-record model = model deleteRecord=(action 'deleteRecord')}}
</div>
</div>
{{/unless}}
</div>
MyRoute
import Ember from 'ember';
export default Ember.Route.extend({
model: function()
{
return this.get('store').queryRecord('cart',{userId:1})
}
});
我的串行
import DS from 'ember-data';
export default DS.JSONSerializer.extend(DS.EmbeddedRecordsMixin, {
primaryKey: 'totalPrice',
attrs: {
orderParts:
{
serialize: 'records',
deserialize: 'records'
}
}
});
我有以下问题:
- 在MyComponent.hbs中,将newCart作为参数传递给删除所有记录还是我要删除的特定记录?
- 关于为什么不从组件调用MyController的任何想法?
- 这是删除烬中记录的正确方法吗?
在此先感谢您。
答案的问题,现在控制器被调用,代码工作正常,但记录没有被删除,我也没有得到一个错误。 – Azmy
'{{action“deleteCartRecord”newCart}}''确保'newCart'是记录。发布代码你在哪里包括 – kumkanillam
'{{action“deleteCartRecord”newCart.partNumber}}'在这里你发送'newCart.partNumber'我想它应该是'{{action“deleteCartRecord”newCart}}' – kumkanillam
