我看到了这段代码:
Sub CustomLabels()
Dim i, myCount, pt
ActiveSheet.ChartObjects("myChart").Activate
myCount = ActiveChart.SeriesCollection(1).Points.Count
For i = 1 To myCount
ActiveChart.SeriesCollection(1).Points(i).ApplyDataLabels
ActiveChart.SeriesCollection(1).Points(i).DataLabel.Text = Range("D" & i + 1).Value
Next i
End Sub
这是相关的测试:
Event.delay.create!(
event_type: event_type,
description: 'Automatically populated',
date: Time.now.utc,
eventable_id: subscription.id,
eventable_type: subscription.class.name,
app_context: app_context)
什么是and_call_original方法?什么是延迟方法?
答案 0 :(得分:2)
:delay方法可能来自Delayed Job,一个排队框架:
' and_call_original'是rspec框架中的委托者。
