Problem when displaying routes in Root Api

Question

I have a file urls.py in the project with my API routes, I am importing the routes and concatenating into a variable called api_urls, to then include the variable with the routes, but when doing this, only the router_user routes appear in the Root API page, because, in order were the first that I added in api_urls. How do I list all the routes on the Root API page?

Urls of the Project

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

from usuarios.urls import router_usuario
from avisos.urls import router_avisos
from boletos.urls import router_boletos
from condominio.urls import router_condominio
from endereco.urls import router_endereco
from registros.urls import router_registros
from reservas.urls import router_reservas
from taxas.urls import router_taxas

api_urls = router_usuario.urls + router_avisos.urls + 
router_boletos.urls + router_condominio.urls \
+ router_endereco.urls + router_registros.urls + router_reservas.urls 
+ router_taxas.urls

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('rest_framework.urls')),
    path('', include(api_urls)),
]

if settings.DEBUG:
    import debug_toolbar
    urlpatterns = [
        path('__debug__/', include(debug_toolbar.urls)),
    ] + urlpatterns

Create a list, add the urls to that list and after that you will have all the urls

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

from usuarios.urls import router_usuario
from avisos.urls import router_avisos
from boletos.urls import router_boletos
from condominio.urls import router_condominio
from endereco.urls import router_endereco
from registros.urls import router_registros
from reservas.urls import router_reservas
from taxas.urls import router_taxas

lista_urls = [router_usuario.urls, router_avisos.urls, 
router_boletos.urls, router_condominio.urls,
router_endereco.urls, router_registros.urls, router_reservas.urls, router_taxas.urls]

api_urls = [row for row in lista_urls]


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('rest_framework.urls')),
    path('', include(api_urls)),
]

if settings.DEBUG:
    import debug_toolbar
    urlpatterns = [
        path('__debug__/', include(debug_toolbar.urls)),
    ] + urlpatterns

You’re right when you say only the first urls of your + appear on the site. This is because you are using the DefaultRouter in all apps and then doing the import and the new list from the .urls.

Following the line of using the DefaultRouter, the correct way of doing the "merge" between them is:

router = routers.DefaultRouter()
router.register("rota-1", Rota1ViewSet)

router2 = routers.DefaultRouter()
router2.register("rota-2", Rota2ViewSet)


router3 = routers.DefaultRouter()
router3.registry.extend(router.registry)
router3.registry.extend(router2.registry)

urlpatterns = [
    path("", include(router3.urls)),
    ...
]

In your case, it would be something like this:

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

from usuarios.urls import router_usuario
from avisos.urls import router_avisos
from boletos.urls import router_boletos
from condominio.urls import router_condominio
from endereco.urls import router_endereco
from registros.urls import router_registros
from reservas.urls import router_reservas
from taxas.urls import router_taxas
from rest_framework import routers

router = routers.DefaultRouter()
router.registry.extend(router_usuario.registry)
router.registry.extend(router_avisos.registry)
router.registry.extend(router_boletos.registry)
router.registry.extend(router_condominio.registry)
router.registry.extend(router_endereco.registry)
router.registry.extend(router_registros.registry)
router.registry.extend(router_reservas.registry)
router.registry.extend(router_taxas.registry)

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('rest_framework.urls')),
    path('', include(router.urls)),
]

If I haven’t forgotten any import or something like that should work.
