Django字段错误消息

Question

我有django形式的字段需要整数。 字段中的默认值为＆＃39; - ＆＃39;。 这意味着当用户忽略该字段时，将返回表单字段错误。 令人讨厌的是，这条消息令人讨厌，而且这个消息很烦人。在里面。

如何摆脱U？

html

<div class="col-sm-1">
   {% with childForm.age as field %}
      <div class="form-group{% if field.errors %} has-error{% endif %}" id="children-age">
          {{ field }}
          {% if field.errors %}<p class="help-block">{% for error in field.errors %}{{ error }}{% endfor %}</p>{% endif %}
       </div>
    {% endwith %}
 </div>

Answer 1

我不确定错误消息为何具有u''前缀。我建议您将选项的值更改为空字符串''。

class TravelGeneralEnquiryChildForm(forms.ModelForm):
    age = forms.ChoiceField(choices=(('','-'),) + tuple(((str(x), x) for x in range(0, 18))))

这样您就会收到错误消息This field is required.，而不是无效的选择错误消息。
