Question

我是django的新手，这个问题令我难过。我看不到错误，现在看了好几个小时！

我试图根据下拉列表的值关闭或打开两个文本字段的验证。如果用户选择索引值8888或9999，则关闭验证 - 这似乎正常（woo hoo !!）。

当用户选择另一个值（不是8888或9999）时，验证将打开，但即使我填写了相关的文本字段，也会保持打开状态。即使填写了文本字段，表单也不会提交，因为仍然会触发验证。

以下是我的forms.py页面中的代码：

    def clean(self):

    cd_wrtdf = super(WorkplaceRelatedTrainingDetailsForm, self).clean()

    if cd_wrtdf['workplace_training_display_type'] == 8888 or cd_wrtdf['workplace_training_display_type'] == 9999:

        self.cleaned_data['workplace_training_institute'] = ''
        self.cleaned_data['workplace_training_date_completed'] = ''
        self.cleaned_data['workplace_training_date_expiry'] = ''

    else:

        if cd_wrtdf['workplace_training_display_type'] == 0:

            self._errors['workplace_training_institute'] = self.error_class([_("This field is required.xxxxxxxxx")])
            del self.cleaned_data['workplace_training_institute']

            self._errors['workplace_training_date_completed'] = self.error_class([_("This field is required.yyyyyyyy")])
            del self.cleaned_data['workplace_training_date_completed']

    return cd_wrtdf

非常感谢任何建议或代码示例。

感谢。

最后，验证工作正常进行！

这是代码（希望这有助于某人）：

    def clean(self):

    cd_wrtdf = super(WorkplaceRelatedTrainingDetailsForm, self).clean()

    if cd_wrtdf['workplace_training_display_type'] == 8888 or cd_wrtdf['workplace_training_display_type'] == 9999:

        self.cleaned_data['workplace_training_institute'] = ''
        self.cleaned_data['workplace_training_date_completed'] = ''
        self.cleaned_data['workplace_training_date_expiry'] = ''

    else:

        if 'workplace_training_institute' in cd_wrtdf and len(cd_wrtdf['workplace_training_institute'].strip()) == 0:

            self._errors['workplace_training_institute'] = self.error_class([_("This field is required.xxxxxxxxx")])
            del self.cleaned_data['workplace_training_institute']

        if 'workplace_training_date_completed' in cd_wrtdf and len(cd_wrtdf['workplace_training_date_completed'].strip()) == 0:

            self._errors['workplace_training_date_completed'] = self.error_class([_("This field is required.yyyyyyyy")])
            del self.cleaned_data['workplace_training_date_completed']

    return cd_wrtdf
