Python正在将- [<Location: London>]转换为伦敦

Question

请原谅我的新手问题，但是我如何转换：

[<Location: London>]或[<Location: Edinburgh>, <Location: London>]等

进入：

“伦敦”或“爱丁堡，伦敦”

一些背景信息来放在上下文中：

Models.py：

class Location(models.Model):
    place = models.CharField(max_length=100)

    def __unicode__(self):
        return self.place

class LocationForm(ModelForm):
    class Meta:
        model = Location

forms.py

class BookingForm(forms.Form):  
    place = forms.ModelMultipleChoiceField(queryset=Location.objects.all(), label='Venue/Location:', required=False)

views.py

def booking(request):
    if request.method == 'POST':
        form = BookingForm(request.POST) 
        if form.is_valid():
                place = form.cleaned_data['place'] 
                recipients.append(sender)
                message = '\nVenue or Location: ' + str(place)
                send_mail('Thank you for booking', message, sender, recipients)
)

Answer 1

打印的是QueryList，而不是单个元素。

u', '.join(x.place for x in Q)

Answer 2

如果您想要更改在shell中打印Django模型的方式，请覆盖__repr__方法。

Answer 3

如果它是您正在打印的查询的结果，请尝试

[x.name for x in result]

如果name是包含位置名称的属性。
