我试图让用户在注册后能够创建和编辑他们的个人资料。我正在使用模型表格。我需要做的是让雇主模型字段填充当前用户。
以下是我的观点:
def update_profile(request, username):
if request.method == 'POST':
edit_profile_form=EditProfileForm(request.POST)
if edit_profile_form.is_valid():
editprofile = edit_profile_form.save(commit=False)
editprofile.employer = request.user.get_profile()
editprofile.save()
edit_profile_form = EditProfileForm()
context = {'edit_profile_form':edit_profile_form,}
return render(request, 'pandaboard/editprofile.html', context)
这是我的模特:
class Profile(models.Model):
employer = models.ForeignKey(User)
company_name = models.CharField(max_length=100)
company_description = models.TextField()
company_website = models.URLField(max_length=200, blank=True)
contact_email = models.EmailField(max_length=100)
contact_name = models.CharField(max_length=100)
def __unicode__(self):
return self.company_name
这是我的模型表格
from django.forms import ModelForm
from pandaboard.models import JobPost, Profile
from django.contrib.auth.models import User
class EditProfileForm(ModelForm):
class Meta:
model = Profile
fields = ['company_name','company_description','company_website','contact_email','contact_name']
答案 0 :(得分:9)
要使用现有模型实例中的值来水合表单,您需要在模型表单上使用instance
参数:
def update_profile(request, username):
profile = request.user.get_profile()
edit_profile_form = EditProfileForm(request.POST or None,
current_user=request.user, instance=profile)
if request.method == 'POST':
if edit_profile_form.is_valid():
editprofile.save()
context = {'edit_profile_form': edit_profile_form}
return render(request, 'pandaboard/editprofile.html', context)
要注入当前的request.user,你可以覆盖__init__
的{{1}},传入一个额外的关键字参数(或arg,它并不重要),然后弹出它在调用super之前的kwargs,所以你没有传递ModelForm一个关键字参数,它没有预料到:
EditProfileForm
现在您不必传递class EditProfileForm(ModelForm):
class Meta:
model = Profile
def __init__(self, *args, **kwargs):
current_user = kwargs.pop('current_user')
super(EditProfileForm, self).__init__(*args, **kwargs)
self.fields['employer'] = current_user
并在视图中手动设置commit=False
的值。
