Django字段錯誤消息

Question

我有一個django格式的字段需要一個整數。 該字段中的默認值是' - '。 這意味着當用戶忽略該字段時，將返回表單字段錯誤。令人討厭的消息有一個惱人的'你'在它。

我該如何擺脫U？

的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

我不知道爲什麼錯誤信息有u''前綴。我建議您將的值更改爲空字符串''。

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

這樣你會得到錯誤信息This field is required.而不是無效的選擇錯誤消息。
