python - Django field error messages -

i have fields in django form require integer. default value in field '-'. means when user ignores field, form field error returned. annoyingly message has annoying 'u' in it.

how rid of u?

the html

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

the error

forms.py

i'm not sure why error message has u'' prefix. suggest change value of choice empty string ''.

class travelgeneralenquirychildform(forms.modelform):     age = forms.choicefield(choices=(('','-'),) + tuple(((str(x), x) x in range(0, 18)))) 

that way you'll error message this field required. instead of invalid choice error message.
