它没有抛出表单验证的个别错误消息。我正在使用PhoneForm并且对于单个字段，应该发生个别错误消息。我检查了它，我无法找到我遗漏的东西。这可能是愚蠢的需要帮助修复。

但是你没有对各个字段进行检查。您正在定义整体clean()方法，并抛出一般错误 - 您所说的只是“此字段是必需的”，而不定义您正在谈论的字段。我不知道你对Django的了解程度如何。

正常的做法是覆盖特定的字段清理方法，例如clean_number1等。你不这样做是正确的，因为每个字段都取决于另一个字段，所以clean()是正确的的地方。

但正如文档所示，您可以使用常规clean方法inject field-specific errors：

self._errors['number1'] = self.error_class(['This field is required'])
del self.cleaned_data['number1']
