Django - 選擇字段顯示鍵，而不是值

Question

我有一堆字段的模型。其中兩個領域有選擇。他們是這樣的：

SNAIL_MAIL_INVOICE_CHOICES = (
    ('Y', 'Yes'), 
    ('N', 'No'), 
) 

SNAIL_MAIL_CHOICES = (
    ('Y', 'Yes'), 
    ('N', 'No'), 
) 

snailMailOnly = models.CharField(max_length = 3, verbose_name = 'Snail Mail Only?', choices = SNAIL_MAIL_CHOICES, default='Y') 
snailMailInvoice = models.CharField(max_length = 3, verbose_name = 'Snail Mail Invoice?', choices = SNAIL_MAIL_INVOICE_CHOICES, default='Y') 

當我表現出Django模板這兩個值，我這樣做是這樣的：

<tr><td>Snail Mail Only?</td><td>{{contact.get_snailMailOnly_display}}</td></tr> 
    <tr><td>Snail Mail Invoice?</td><td>{{contact.get_snailMailInvoice_display}}</td></tr> 

的問題是，雖然第一場snailMailOnly顯示器的選擇Yes和No正確，第二個字段snailMailInvoice只顯示Y和N。

我在這裏做錯了什麼？

感謝

Answer 1

好的 - 我想通了。

我意識到有一件事與我的CSV文件中的snailMailInvoice字段是每行上的LAST字段有關。因此，在行的末尾有一個回車。我認爲這是一個\n - 因此在我的MySQL命令導入CSV，我國terminated by '\n'。

但是，MySQL在每行上都選取了'\ r'，並將其添加到snailMailInvoice字段中。因此，每個記錄都有一個Y或一個N與\r附加。

我修改了我的MySQL導入語句：lines terminated with '\r\n'現在一切都按預期工作。

經驗教訓。

感謝您的幫助。

沒有理由爲根據您發佈的代碼。 「Y」和「N」在一個點上的顯示值爲SNAIL_MAIL_CHOICES？您的Web服務器可能不會拉取最近的代碼。

如果您正在開發中，請嘗試殺死runserver（CTRL + C）並重新啓動它。

如果您正在生產，請重新啓動您的網絡服務器和它所代理的進程（如果有的話），如uwsgi。

您還可以嘗試刪除任何在您的項目中放置的*.pyc文件。 * nix外殼中的快速簡單的方法是（從您的項目目錄）：

$ find . -name="*.pyc" -exec rm {}\;
