Question

我正在尝试使用Django 1.11和python为我的工作设置一些东西，它将显示登录用户提交的项目列表。用户可以单击项目名称，如果需要，用户将转到该项目进行编辑。我有它显示项目列表但是当用户点击名称时我得到一个错误。当只有一个项目显示给该用户时，它工作正常。错误和我的代码如下。

MultipleObjectsReturned at / edit / get（）返回多个Project - 它返回2！请求方法：GET 请求网址：http://127.0.0.1:8000/edit/ Django版本：1.11 异常类型：MultipleObjectsReturned 例外价值：
get（）返回多个Project - 它返回2！

url.py

urlpatterns = [
    url(r'^index/',views.Index.as_view(),name='index'),
    url(r'^form/', views.Form.as_view(), name = 'form'),
    url(r'^edit/', views.EditProject.as_view(), name = 'editProject'),

]

views.py

class Index(LoginRequiredMixin,ListView):
    template_name = 'sitename/index.html'
    form_class = IndexForm

    def get_queryset(self):
        return Project.objects.filter(user=self.request.user)

class EditProject(LoginRequiredMixin, UpdateView):
template_name = 'irbSite/form.html'
form_class = ProjectForm
success_url = reverse_lazy('irbSite:index')

# works only when there is 1 project object
def get_object(self):
    return Project.objects.get(user=self.request.user)

的index.html

{% if user.is_authenticated %}

   {% if project_list %}
     <tr>
        <th>Project Number</th>
        <th>Project Name</th>
        <th>Is Complete</th>
        <th>Is Approved</th>
    </tr>

{% for project in project_list  %}
    <tr>
     <td><a href="{% url 'irbSite:editProject'%}">{{project.project_id}}</td>
    <td>{{project.project_name}}</a></td>
    <td>{{project.is_complete}}</td>
    <td>{{project.is_approved}}</td>
{% endfor %}
    </tr>
{% else %}
 <p>You dont have any current IRB forms. Select "Submit New Project" on the left to start one.<p>

Answer 1

在查询时使用.filter获取多个对象。

<强>实施例

def get_object(self):
    return Project.objects.filter(user=self.request.user)

Django 1.11查询不起作用
