如何使用Django模型字段创建单选按钮
#models.py
GENDER_CHOICES = (
('M', Male),
('F', 'Female')
)
class Profile(models.Model):
gender = models.CharField(choices=GENDER_CHOICES, max_length=128)
上面的字段呈现为选择字段,但我想将其作为单选按钮.

</div>
</body >
</html>
我的angular.js:
angular.module("app", ["chart.js"])
// Optional configuration
.config(['ChartJsProvider', function (ChartJsProvider) {
// …我想request在save()方法中作为参数获取.
models.py
class Profile(models.Model):
uuid = UUIDField(auto=True)
user = models.ForeignKey(User)
name = models.CharField(max_length=128)
dob = models.DateField()
class Meta:
db_table = 'profile'
def save(self,*args,**kwargs):
if not self.pk:
self.user_id = 2 #here i need request.user instead of 2
super(Profile,self).save(*args,**kwargs)
forms.py
class ProfileForm(forms.ModelForm):
class Meta:
model = Profile
exclude = ['uuid','user']
views.py
def add(request):
profile_form = ProfileForm(request.POST)
profile_form.save()
而不是2我想传递的价值request.user.我该怎么做.如果问题不正确,有人请更正问题.
我是jQuery的新手.我尝试从中获取数据时出错fileresult.php.
fileresult.php
$return_arr = array();
$row_array['status'] = 'Ok';
$row_array['message'] = 'good'
array_push($return_arr, $row_array);
echo json_encode($return_arr);
JSON输出
[{"date":"2014-03-15","status":"ok","message":"good"}]
get_result.js
$.post('file.php', $("form").serialize(), function(data) {
var status = data['status'];
alert(status);
});
当我提醒数据时,它显示undefined.有人请帮帮我.如何显示正确的数据.
