为Django表单编码UTF-8

Question

I have a contact form

class ContactForm(forms.Form):
    name = forms.CharField(required=True, max_length=100, label=_('firstname'))
    mail = forms.EmailField(required=True, max_length=150, label=_('mail'))

def display(request):
    form = ContactForm(request.POST)
    if form.is_valid(): 
       ...
    else:
       form = ContactForm()  

    return render_to_response('contact.html', {'contact_form' : form}, context_instance=RequestContext(request))

With from django.utils.translation import gettext_lazy as _

In my template contact.html

<form action="#" method="post" >{% csrf_token %}
    {{ contact_form.as_p  }}
    <input type="submit" value="Send" />
</form>

I have this error

'ascii' codec can't encode character u'\\xe9' in position 2: ordinal not in range(128)

Unicode error hint

The string that could not be encoded/decoded was: Prénom

The problem is _('firstname')) . But it works when

• I put .encode('utf8') at the end it's solved.
• I use the string without the translation tool
• I use another text like _('other string')
• I add string at the end : _('firstname')+''
• I use the translation in the view : {% trans "firstname" %}

But I don't want to do this in all attributs of my contact form (which contains more attributs).

How can I do that for name and email both ?

Thanks

Answer 1

解决办法是更换gettext_lazy由ugettext_lazy因为字符串Prénom包含一个特殊的Unicode信é

Answer 2

Type on the first line:

# -*- coding: utf-8 -*-

Python recognises this line as instructions of encoding type for your entire file.

You don't specify whether you use ModelForms or not, but can you check in your template that your browser will correctly encode the submitted data with the content='text/html; charset=UTF-8' content='text/html; charset=UTF-8' attribute in the form tag? Like:

<form action='/someurl' method='post' content='text/html; charset=UTF-8'>
