python - 替换 SQL 查询中的值

Question

我创建了一个应用程序，按照以下代码从某些数据库项目打印试算表。

当前打印结果如下例所示:

我如何才能用空格替换表中的“0”，以便其显示如下:

View .py

def Kyletrb(request):
    all =  'SELECT Master_Sub_Account , cAccountTypeDescription , Debit , Credit FROM [Kyle].[dbo].[PostGL] '\
                    'Inner JOIN [Kyle].[dbo].[Accounts] '\
                    'on Accounts.AccountLink = PostGL.AccountLink '\
                    'Inner JOIN [Kyle].[dbo].[_etblGLAccountTypes] as AccountTypes '\
                    'on Accounts.iAccountType = AccountTypes.idGLAccountType'

    cursor = cnxn.cursor();
    cursor.execute(all);
    xAll = cursor.fetchall()
    cursor.close()
    xAll_l = []
    for row in xAll:
        rdict = {}
        rdict["Description"] = row[0]
        rdict["Account"] = row[1]
        rdict["Credit"] = row[2]
        rdict["Debit"] = row[3]
        xAll_l.append(rdict)

    creditTotal = ' Select ROUND(SUM(Credit) , 2) FROM [Kyle].[dbo].[PostGL] WHERE Credit <> 0.0'
    cursor = cnxn.cursor();
    cursor.execute(creditTotal);
    xCreditTotal = cursor.fetchone()

    debitTotal = ' Select ROUND(SUM(Debit) , 2) FROM [Kyle].[dbo].[PostGL] WHERE Debit <> 0.0'
    cursor = cnxn.cursor();
    cursor.execute(debitTotal);
    xDebitTotal = cursor.fetchone()

    return render(request , 'main/Kyletrb.html' , {"xAlls":xAll_l , 'xCreditTotal':xCreditTotal , 'xDebitTotal':xDebitTotal})

我怎样才能做到这一点？ 如果有人有示例/一些文档，请分享。

Answer 1

要以最简单的方式实现此结果，您可以在模板中实现 if else。

举个例子

借记卡

<td>
    {%if xAll.Debit > 0%}
    {{xAll.Debit}}
    {%endif%}
</td>

信用

<td>
    {%if xAll.Credit > 0%}
    {{xAll.Credit}}
    {%endif%}
</td>

如果您关心代码的外观，那么您可以创建自定义小部件。
