Django没有调用函数

Question

我的 django 主站点网址

from django.contrib import admin
from django.urls import path,include

urlpatterns = [

    path('ways/', include('ways.urls')),
    path('admin/', admin.site.urls),

应用网址

urlpatterns = [

    path('newWay/', views.newWay, name='newWay'),
    path('waySolved/', views.update_way, name='update_way'),


]

项目结构

但是每当我点击http://localhost:8000/ways/waySolved/ 它说未找到：/ways/waySolved/ 但http://localhost:8000/ways/newWay/ 完美运行。 在视图中我有这两种功能。 更新方式

def update_way(request):
    way_id= request.GET.get('way_id', None)
    token=request.GET.get('token', None)

    if way_id is not None and token is not None:
        token = token.replace("\"", "")

        community_osm_cur.execute("""SELECT  latitude ,longitude from (SELECT * from (SELECT  
            latitude,longitude,id from  current_nodes where id in (Select node_id from 
            current_way_nodes where way_id='%s' ORDER BY  sequence_id asc )) AS temp1
            Inner join
            (Select node_id,sequence_id from current_way_nodes where way_id='%s' 
            ORDER BY  sequence_id asc ) As temp2 on temp1.id=temp2.node_id
            order by sequence_id asc) As temp3""", ((int)(way_id), (int)(way_id),))
        nodes_list = community_osm_cur.fetchall()

        coords = []
        if len(nodes_list)>0:

            for node in nodes_list:
                lat = node[0] / 10000000
                lng = node[1] / 10000000
                coords.append([lat, lng])

            position_hash = hashlib.sha3_256(json.dumps(coords).encode()).hexdigest()
            community_osm_cur.execute("select user_id from oauth_tokens where secret = %s", (token,))
            id = community_osm_cur.fetchone()[0]



            updated_way_cur.execute("""INSERT INTO updated_ways (way_id,node_hash) values 
              (%s,%s) on conflict(way_id)  do update set node_hash=%s""",
              (way_id,position_hash,position_hash,))
            updated_way_cur.execute("Delete from distribution where user_id=%s and  id = %s ",(id,way_id,))
            updated_way_con.commit()
            return HttpResponse(status=200)
    return HttpResponse(status=404)

Answer 1

在您看来，这似乎是一个问题，而不是您的 URL 模式。

您正在访问/ways/waySolved/?way_id=13232323，前两行是。

def update_way(request):
    way_id= request.GET.get('way_id', None)
    token=request.GET.get('token', None)

查询字符串中没有token，因此您将拥有way_id=13232323 和token=None。

然后你的代码会：

if way_id is not None and token is not None:
    ...
return HttpResponse(status=404)

由于token 为None，因此视图跳转到最后，因此预期会出现404 响应。
