我有一个表单,用户输入有关位置的信息。我正在尝试制作更新表单,以便用户可以单击某个位置上的更新按钮,并使用该位置已存在的数据填充更新表单。我遵循Django文档,但我得到一个空白屏幕。我不确定如何让它引用要更新的位置。这是我到目前为止。Django更新表单?
models.py
class Location(models.Model):
# Details on location
views.py
def locations(request):
return render_to_response('locations/locations.html', {'locations': Location.objects.all() })
def location(request, location_id=1):
return render_to_response('locations/location.html', {'location': Location.objects.get(id=location_id) })
def create(request):
if request.POST:
form = LocationForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect('/accounts/loggedin/locations/all/')
else:
form = LocationForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('locations/create_location.html', args)
def edit_location(request):
if request.POST:
form = LocationUpdate(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect('/accounts/loggedin/locations/all/')
else:
form = LocationUpdate()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('locations/location_update.html', args)
forms.py
from django.views.generic.edit import UpdateView
from models import Location
class LocationForm(forms.ModelForm):
class Meta:
model = Location
exclude = ('timestamp', 'updated')
class LocationUpdate(UpdateView):
model = Location
template_name_suffix = '_update_form'
url.py
url(r'^accounts/loggedin/location/update/$', 'assessments.views.edit_location'),
location_update.html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="update" />
</form>
</body>
</html>
,或者它应该在location.html去。如果我在那里添加它,我得到一个CSRF verification failed
错误
<div class="row">
<div class="col-md-4">
<dl class="dl-horizontal">

<dd>{{ location.id }}</dd>
<br />

这是您的location_update.html的完整代码吗?你可能没有扩展另一个模板? – 2014-09-24 09:29:17
出于测试目的,它只是得到了html标题和body标签。一旦它正在工作,我会将其添加到模板。它是否需要成为location.html的一部分? – 2014-09-24 09:31:09
我不明白这个答复。这是location_update.html的完整代码吗?如果没有,请发布完整的代码。另外,请正确解释*您看到的内容。你有什么表现吗?当你查看源代码时你看到了什么? – 2014-09-24 09:33:10
