当我转到

/projects/some number

时，我在/projects/1处得到TypeError/ “Project”对象不可编辑

我是个新手，不知道哪里出了错

---

我使用的是Djnago 3.0.10

写以下内容毫无意义：

{% for project in projectss %}
    …
{% endfor %}

要呈现变量，请使用双花括号，因此

{{…}

，而不是

{…}

对于

NoReverseMatch

错误，您需要为视图提供一个正确的名称，因此：

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.home),
    path('projects/', views.project),
    path('projects/<int:project_id>/', views.detail, name='detail')
]

urlpatterns=[
路径（'admin/'，admin.site.url），
路径（“”，视图。主页），
路径（'projects/'，views.project），
路径（'projects/'，views.detail，name='detail'）
]

我认为您没有正确定义模板目录。它不知道从哪里获取模板。请尝试在设置中的

模板['DIRS']

中添加

'main/templates/'

。py您应该做一次更改，而不是发布整个代码。非常感谢
