我试图在我的Django帐户注册表单中添加动态下拉列表。
forms.py:
class CompanySignupForm(account.forms.SignupForm):
first_name = forms.CharField(
label="First Name",
max_length=30,
widget=forms.TextInput(),
required=True)
last_name = forms.CharField(
label="Last Name",
max_length=30,
widget=forms.TextInput(),
required=True)
company = forms.CharField(
label="Company Name",
max_length=60,
widget=forms.TextInput(),
required=True)
models.py:
class EmployerProfile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL)
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=30)
company = models.CharField(max_length=40)
def __unicode__(self):
return self.company
问题是,如果我想要这个领域"公司"要成为一个由大约10,000个条目组成的下拉列表,最好的方法是什么?我应该使用JS和JSON数据吗? jQuery的自动完成?我只想以最有效的方式做到这一点。
答案 0 :(得分:1)
您确定要获得10,000个条目的下拉菜单吗?是的,在@Override
protected void onNewIntent(Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SEARCH)) {
SpannableString user_query_spannable = (SpannableString) intent.getCharSequenceExtra(SearchManager.USER_QUERY);
//if this was a voice search
if (user_query_spannable == null) {
//Log, send Analytics hit, etc.
//Then perform search as normal...
performSearch(intent.getStringExtra(SearchManager.QUERY));
} else {
//Log, send Analytics hit, etc.
//Then perform search as normal
performSearch(intent.getStringExtra(SearchManager.QUERY));
}
}
}

但我会选择使用http://django-autocomplete-light.readthedocs.org/en/master/
的自动填充字段
