我的rails应用程序模型中有两种方法。
sSendTo = Sheet1.Range.Columns(C) & lLastRow).Value
如果我们可以从上面的方法中看到，两者都做了几乎相似的查询，唯一的区别是在Sub Jose_SendEmailDueDateReached()
Dim OutApp As Object
Dim OutMail As Object
Dim lLastRow As Long
Dim lRow As Long
Dim sSendTo As String
Dim sSendCC As String
Dim sSendBCC As String
Dim sSubject As String
Dim sTemp As String
Set OutApp = CreateObject("Outlook.Application")
OutApp.Session.Logon
' Change the following as needed
sSendTo = Sheet1.Range.Columns(C) & lLastRow).Value
sSendCC = "Test@123.com"
sSendBCC = ""
sSubject = Range("A2").Value & " Progress Photos Due"
lLastRow = Cells(Rows.Count, 3).End(xlDown).Row
For lRow = 2 To lLastRow
If Cells(lRow, 6) <> "Sent" Then
If Cells(lRow, 5) <= Date Then
Set OutMail = OutApp.CreateItem(0)
On Error Resume Next
With OutMail
.To = sSendTo
If sSendCC > "" Then .CC = sSendCC
If sSendBCC > "" Then .BCC = sSendBCC
.Subject = sSubject
sTemp = "Hello," & vbCrLf & vbCrLf
sTemp = sTemp & "The due date has been reached "
sTemp = sTemp & "for this project:" & vbCrLf & vbCrLf
' Assumes project name is in column B
sTemp = sTemp & " " & Cells(lRow, 2) & vbCrLf & vbCrLf
sTemp = sTemp & "Please take the appropriate"
sTemp = sTemp & " action." & vbCrLf & vbCrLf
sTemp = sTemp & "Please forward photos to Test@greenscreen.com. " & vbCrLf & vbCrLf & vbCrLf & vbCrLf
sTemp = sTemp & "Thank you."
.Body = sTemp
' Change the following to .Send if you want to
' send the message without reviewing first
.Display
End With
Set OutMail = Nothing
Cells(lRow, 6) = "Sent"
Cells(lRow, 7) = "E-mail sent on: " & Now()
End If
End If
Next lRow
Set OutApp = Nothing
MsgBox ("Clear Stamp")
Range("F2").ClearContents
Range("G2").ClearContents
MsgBox ("Stamp Cleared")
End Sub
中有额外的连接和where def questions_mastered_for(user_id, question_group_ids)
res = UserAnswer
.joins('INNER JOIN question_group_questions ON user_answers.question_id = question_group_questions.question_id')
.joins('INNER JOIN marks ON user_answers.id = marks.user_answer_id')
.group('question_group_questions.question_group_id')
.where(question_group_questions: { question_group_id: question_group_ids })
.where(user_answers: { user_id: user_id })
.where("(marks.boolean_mark_correct = true AND marks.mark_type = 'boolean') OR (marks.fraction_numerator = marks.fraction_denominator AND marks.mark_type = 'fraction')")
.pluck('question_group_questions.question_group_id', 'COUNT(DISTINCT(user_answers.question_id))')
question_group_mastery = {}
question_group_ids.each { |question_group_id| question_group_mastery[question_group_id] = 0 }
res.each { |data| question_group_mastery[data.first] = data.second }
question_group_mastery
end
def questions_attempted_for(user_id, question_group_ids)
res = UserAnswer
.joins('INNER JOIN question_group_questions ON user_answers.question_id = question_group_questions.question_id')
.group('question_group_questions.question_group_id')
.where(question_group_questions: { question_group_id: question_group_ids })
.where(user_answers: { user_id: user_id })
.pluck('question_group_questions.question_group_id', 'COUNT(DISTINCT(user_answers.question_id))')
question_group_attempted = {}
question_group_ids.each { |question_group_id| question_group_attempted[question_group_id] = 0 }
res.each { |data| question_group_attempted[data.first] = data.second }
question_group_attempted
end
表的条件。
我读了一些文章，说这个特殊用例通常可以使用Query Object解决，但我想知道如何正确实现它？
我很感激的任何建议。
