我有一个除非条件,我想找出满足此条件的记录数,除非条件。
可以在ember中执行此操作吗?
编辑:
{{#each model.orderParts as |newCart|}}
{{#unless newCart.isGeneric}}
<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 delivered">{{env.APP.LowInStock}}</div>
{{else}} {{#if (eq newCart.promiseQty '0')}}
<div class="order-status delivered">{{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>
{{/unless}} {{/each}}
我想要的是找出满足这种条件的记录数
答案 0 :(得分:1)
genericFalseCount: Ember.computed.filterBy('model.orderParts','isGeneric',false)
以上计算属性将为您提供计数。
