Как использовать обратный URL в приложении, чтобы указать шаблон другого приложения?

/ 13 июня 2019

У меня есть два приложения: simulation_api и building_data. У каждого есть шаблоны и URL. URL-адреса, которые я импортирую в моей основной конфигурации.

В моем шаблоне Simulation_api я хотел бы установить ссылку на мой подробный вид данных здания.

Это то, что я пытаюсь (в моем шаблоне Simulation_api), который выдает мне ошибку (django.urls.exceptions.NoReverseMatch): 

{% for item in simulations.project.buildinggroup_set.all %}
               <a href="{% url "detail_building_group" item.id %}">{{ item.description }}</a>
 {% endfor%}

Цикл for работает, проблема в URL, который я пытаюсь изменить.

Я изменил это в моих моделях building_data: 


class BuildingGroup(models.Model):
    name           = models.CharField(max_length=500, null=True, blank=True)
    project               = models.ForeignKey(Project, on_delete=models.CASCADE)


    def get_absolute_url(self):
        return reverse("detail_building_group", kwargs={"id" : self.id})

Я думаю, что проблема в том, что я изменяю URL в одном приложении, но он не распознается в шаблоне другого приложения. Но, может быть, это тоже что-то еще ...

У кого-нибудь есть идея? Большое спасибо заранее! Очень ценится!

Не уверен, что это полезно, но вот моя упрощенная модель для симуляции: 

class Simulation(models.Model):
    project                 = models.ForeignKey(Project, on_delete=models.CASCADE)

мои URL-адреса building_data 

app_name = 'buildings'
urlpatterns = [
    path('list/building-group/<int:id>/', DetailBuildingGroupView.as_view(), name="detail_building_group"),

]

Мой след: 

django.urls.exceptions.NoReverseMatch
django.urls.exceptions.NoReverseMatch: Reverse for 'detail_building_group' not found. 'detail_building_group' is not a valid view function or pattern name.

Я решил это следующим образом:

Я добавил пространство имен к своим URL в моей основной конфигурации.

Затем я изменил его так: 

    def get_absolute_url(self):
        return reverse("buildings:detail_building_group", kwargs={"id": self.id})

, тогда как buildings - это мое пространство имен, а detail_building_group - это мое URL-имя.

Также мне пришлось добавитьURL-адрес моего другого приложения в URL, поэтому он распознал URL.

Спасибо JPG за то, что он направил меня в правильном направлении!
