如何根据django中的用户输入将值存储在模型中？

对于给定的用户选择的时间段（应该有时间，俱乐部，日期和法庭相关联的时间段），我如何将类名为“预留”字段的值存储在“用户名”字段中？如何根据django中的用户输入将值存储在模型中？

def vote(request, club_id): 
    if 'username' in request.POST and request.POST['username'] and 'slot' in request.POST and request.POST['slot']: 
     username = request.POST['username'] 
     slot = request.POST['slot'] 
     #save the value stored in "username" to the "reservation" field in class Opening with the other associated data (club, time, day, court) 
     return HttpResponseRedirect('reserve/templates/booked.html',{'username':username, 'slot':slot}) 
    else: 
     return render_to_response('reserve/templates/vote.html', {'error': True})

Avail_times.html：

<form action="/clubs/{{ club.id }}/vote/" method="post"> 
{% csrf_token %} 
{{ today }}<br> 
{% for slot in open_slots %} 
    <input type="checkbox" name="slot" id="slot{{ forloop.counter }}" value="{{ slot.id }}" /> 
    <label for="slot{{ forloop.counter }}">{{ slot.slot }} on Court {{slot.court}}</label><br /> 
{% endfor %} 

<br> 
{{ tomorrow }}<br> 
{% for slot in tom_open_slots %} 
    <input type="checkbox" name="slot" id="slot{{ forloop.counter }}" value="{{ slot.id }}" /> 
    <label for="slot{{ forloop.counter }}">{{ slot.slot }} on Court {{slot.court}}</label><br /> 
{% endfor %}  
<input type="text" name="username" /> 
<input type="submit" value="Reserve" />

型号：

from django.db import models 
import datetime 

class Club(models.Model): 
    establishment = models.CharField(max_length=200) 
    address = models.CharField(max_length=200) 
    def __unicode__(self): 
     return self.establishment 

class Court(models.Model): 
    club = models.ForeignKey(Club) 
    day = models.ForeignKey(Day) 
    court = models.IntegerField(max_length=200) 
    def __unicode__(self): 
     return unicode(self.court) 

class Opening(models.Model): 
    club = models.ForeignKey(Club) 
    day = models.DateField('date') 
    court = models.ForeignKey(Court) 
    slot = models.TimeField('slot') 
    reservation = models.CharField(max_length=200) 
    def __unicode__(self): 
     return unicode(self.slot)

如果您想更新Opening模型，那么你需要知道哪一个。

将opening_id写入表单中。我不确定你的插槽和开口是如何相关的，所以你必须弄清楚这一点。

我通常用get_object_or_404来获得相关Opening

username = request.POST['username'] 
opening = get_object_or_404(Opening, id=request.POST['opening_id']) 
opening.reservation = username 
opening.save()

你想也想检查允许用户更新开放。
