Ubuntu 12.04でPython 2.7でDjango 1.4を使用しています。
編集:同じ問題が再発したように見えるため、この質問の誤った部分をいくつかクリアしています。それは素晴らしく機能していました-私は変更を加えていません-そして今は失敗しています. どうしたの?
これは基本的にビューがどのように見えるかです:
@login_required
def request_new_project(request):
"""
.. function:: request_new_project()
Collect information to call the form used to create a new project
:param request: Django Request object
"""
user_dict = { 'rsb_username' : request.user.username}
form = CreateProject(initial = user_dict)
data = { 'user' : request.user }
data.update(csrf(request))
data.update({ 'form' : form })
return render_to_response("create_project.html", data)
@login_required
def add_project(request):
"""
.. function:: add_project()
Add a project for the user
:param request: Django Request object
"""
if (request.method == "POST"):
user = User.objects.get(username = request.POST.get('rsb_username'))
userProfile = UserProfile.objects.get(user = user)
new_project = Projects(client = userProfile,
project_name = request.POST.get('rsb_project_name'),
description = request.POST.get('rsb_description'),
budget = request.POST.get('rsb_budget'),
time_frame = request.POST.get('rsb_time_frame'),
time_frame_units = request.POST.get('rsb_time_frame_units'),
contact = request.POST.get('rsb_point_of_contact'),
contact_email = request.POST.get('rsb_contact_email'),
contact_phone = request.POST.get('rsb_contact_phone'),
price_quote = 0,
eta = 'To Be Determined',
current_status = 'Waiting for quote',
)
new_project.save()
return view_projects(request)
次のエラーが表示されます。
Cannot assign "<UserProfile: UserProfile object>": "Projects.client" must be a "User" instance.
モデルチェンジはしていません。
# Create a table for users

user = models.OneToOneField(User)

助言がありますか?
rsb_projects
更新 1: 実際のデータベースから、制約
の 1 つが次のようになっていることがわかります。rsb_projects_client_id_fkey (client_id) REFERENCE rsb_userprofile (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION DEFERRABLE INITIALLY DEFERRED
それが役に立ったら...
データベースに対して を定義ForeignKey
したにもかかわらず、 IDが必要なようです。models.py
User
UserProfile
考え?
