Django 表单不接受基于 dict 的自定义标签 --- AttributeError unicode 对象没有属性获取

Question

我正在尝试使用如下所示的类在 Django 中编辑表单标签：

from django import forms
class Form(forms.Form):
    e = {}
    gender = forms.ChoiceField(choices = ())
    #_remaining variables_
    def __init__(self, lang):
         t = Translation.objects.get(template_file = 'VirasatForm')
         startcount = t.id +1
         endcount = t.page_entries.count() + t.id + 1
         for i in range(startcount, endcount):
            w = t.page_entries.get(id = i).template_file
            if lang == 'en':
                r = t.page_entries.get(id = i).enTranslate
            elif lang == 'lsd':
                r = t.page_entries.get(id = i).lsdTranslate
            elif lang == 'ar':
                r = t.page_entries.get(id = i).arTranslate
            self.e[w] = r

       super(Form,self).__init__(self, lang)
       self.fields['gender'].choices = (('m',self.e['Male']),('f',self.e['Female']))
       self.fields['gender'].label = self.e['gender'])

这里的问题是我得到的只是 AttributeError: 'unicode' object has no attribute 'get'

提前致谢

您可以像这样动态创建表单：

class Form(forms.Form):
    def __init__(self, gender_choices, *args, **kwargs):
        super(Form, self).__init__(*args, **kwargs)
        self.fields['gender'] = forms.ChoiceField(choices=gender_choices)

示例用法：

>>> choices = (('m', 'Male'), ('f', 'Female'))

>>> f = Form(choices)

>>> print f
<tr><th><label for="id_gender">Gender:</label></th><td><select name="gender" id="id_gender">
<option value="m">Male</option>
<option value="f">Female</option>
</select></td></tr>
