Question

我有一个项目（learning_log），您可以在其中添加主题，在这些主题中可以添加条目。我有一个编辑条目选项，但我也想添加一个删除条目选项。我做了以下事情，但是当我尝试在heroku上加载它时仍然出现内部错误。：

输入网址...

urls.py

@foreach($estates as $est)

    var result = $.ajax({
        url: 'https://maps.googleapis.com/maps/api/geocode/json?address={{$est->address}}&key={{env('GOOGLE_MAPS_API')}}'
    })

    result.done(function(data) {

        {{ get required data and save to somewhere }}

    });

@endforeach

撰写视图

views.py

import * as firebase from 'firebase/app'
import 'firebase/auth'
import 'firebase/database'
import 'firebase/storage'

export default {
  actions: {
    fetchUserData ({commit, getters}) {
      commit('setLoading', true)
      firebase.database().ref('/users/' + getters.user.id + '/registerations/').once('value')
        .then(data => {
          const dataPairs = data.val()
          let registeredMeetups = []
          let swappedPairs = {}
          for (let key in dataPairs) {
            registeredMeetups.push(dataPairs[key])
            swappedPairs[dataPairs[key]] = key
          }
          const updatedUser = {
            id: getters.user.id,
            registeredMeetups: registeredMeetups,
            fbKeys: swappedPairs
          }
          commit('setLoading', false)
          commit('setUser', updatedUser)
        })
          .catch(error => {
            console.log(error)
            commit('setLoading', false)
          })
    }
  }
}

制作了html模板

delete_entry.html

urlpatterns = [
    #...

    #Page for deleting an entry
    path('delete_entry/',views.delete_entry,name='delete_entry'),

    ]

从我的“编辑条目页面”链接到它

edit_entries.html

def delete_entry(request, entry_id):
  """Delete an existing entry"""
  entry = get_object_or_404(Entry,id=entry_id) #getting the entry object the user wants to delete
  topic=entry.topic
  check_project_owner() #This is a custom function (I know it works) Making sure the person who wants to delete it is the owner
  entry.delete() #Delete the entry
  context = {'entry':entry} #I don't even think we need to pass this but I just want to be safe and pass something
  return render(request, 'learning_logs/delete_entry.html', context)

在您的网址格式中，没有参数传递给视图。但是您的视图需要一个名为entry_id的额外参数。更新您的网址以解决此问题：

url_patterns = [
    ...
    #Page for deleting an entry
    path('delete_entry/<int: entry_id >/',views.delete_entry,name='delete_entry'),
]

尝试为django / heroku上的博客条目提供删除选项
