我有'艺术家'表和'表演'表。性能表有一个性能时间字段,它是一个时间戳。
在回复我的艺术家数据时,我也会建立关系以获得表演:
Use "Class.URL"
Use "Class.JSON"
Sub Initialize
'*** Local Notes classes used in agent
Dim session As New NotesSession
Dim db As NotesDatabase
Dim thisdb As NotesDatabase
Dim view As NotesView
Dim col As NotesViewEntryCollection
Dim entry As NotesViewEntry

'*** Custom classes
Dim url As URLData
Dim json As JSONData
'*** Local variables to hold arguments passed from URL
Dim startdate As String
Dim enddate As String
'*** Other local variables
Dim jsontext As String
'*** Create new URLData object
Set url = New URLData()
'*** Create new JSONData object
Set json = New JSONData()
'*** Check start date and convert from ISO to US date format
If url.IsValue("start") Then
startdate = ISOtoUS(url.GetValue("start"))
Else
startdate = "01/01/1980"
End If
'*** Check end date and convert to US date format
If url.IsValue("end") Then
enddate = ISOtoUS(url.GetValue("end"))

jsontext = ""
Set db = session.CurrentDatabase
Set view = db.GetView("Events")
Set col = view.AllEntries
Set entry = col.GetFirstEntry()
Do Until entry Is Nothing
If CDat(entry.ColumnValues(0))>=CDat(startdate) Then
If CDat(entry.ColumnValues(0))<=CDat(enddate) Then
Call json.SetValue("id", CStr(entry.ColumnValues(5)))
Call json.SetValue("title",CStr(entry.ColumnValues(3)))
Call json.SetValue("start", Format$(CDat(entry.ColumnValues(7)),"mm/dd/yyyy hh:nn ampm"))

Call json.SetValue("className","eventData eventData" + CStr(entry.ColumnValues(6)))
Call json.NoStatus()
'*** Make the entry editable (change date/time)
Call json.SetBoolean("editable", True)
End If
End If
jsontext = jsontext + json.GetJSON() + "," + Chr$(13)
Set entry = col.GetNextEntry(entry)
Loop
If Len(jsontext)>4 Then
jsontext = Left$(jsontext,Len(jsontext)-2)
End If
Print "[ " + jsontext + " ]"
End Sub
%REM
Function ISOtoUS
Description: Convert ISO date to US date,
e.g 2015-05-08 to 05/08/2015
%END REM
Function ISOtoUS(dateISO As String) As String
Dim tmp As String
' 2015-02-03
tmp = Mid$(dateISO,6,2) + "/"
tmp = tmp + Mid$(dateISO,9,2) + "/"
tmp = tmp + Left$(dateISO,4)
ISOtoUS = tmp
End Function
我现在要做的是为演出关系添加另一部分信息,这将显示使用演奏时间字段的演出时间。
我在其他地方使用不同格式的字段数据,所以不想使用mutator。
谢谢!
答案 0 :(得分:1)
你仍然可以使用mutator。我们假设您的Performance
模型有一个time
字段。
public function getModifiedTimeAttribute() {
return $this->time . ' and something else!';
}
您要$performance->modified_time
访问的。默认情况下,此模型字段不会存在于模型的Laravel阵列/ JSON输出中,但您可以将其添加到模型中以使其显示在那里:
protected $appends = ['modified_time'];
答案 1 :(得分:0)
您可以在Performance
模型中使用动态属性,如下所示:
class Performance extends Model
{
[...]
public function getTimeToNextAttribute()
{
//calculate Time to next Performance and return it
}
}
然后,您可以通过$ performance-&gt; time_to_next访问此媒体资源。
