相关疑难解决方法(0)

我在我的Django应用程序中添加自定义验证到我的表单和自定义字段.我希望能够在触发错误时修改字段的值.例如,如果出现错误,则应使用clean()更正的字段值重新显示表单,并显示错误消息"下面已更正数据.再次单击"保存以确认这些更改是否正常"

我已经尝试在cleaning_data []中返回修改后的数据,但它不起作用.它正确显示错误,但在重新显示表单时,不会使用更正后的HTML更新字段值.

class T34AtividadeForm(ModelForm):
    def clean(self):
        # Return cleaned html
        error,html = fix_imgs(cleaned_data.get("a34_descricao"))
        if error:
            msg = u'Data has been corrected below. Click save again to confirm if these changes are OK';
            self._errors['a34_descricao'] = ErrorList([msg])
            # This doesn't work
            cleaned_data["a34_descricao"] = html
            # This doesn't work either
            self.a34_descricao = html

    return cleaned_data

我也喜欢用字段做同样的事情,但由于错误是由异常触发的,我没有机会返回修正后的值.与表单clean()方法一样,错误显示正确,但值不会更新.

class HTMLField(CharField):
    widget = HTMLTextarea

    def clean(self, value):
        value = super(HTMLField,self).clean(value)
        error,html = fix_imgs(value)
        if error:
            # This doesn't work
            self.value = html
            raise forms.ValidationError(u'Data has …
