Django:如何链接到特定用户? [英] Django: how to link to specific user?

问题描述

我正在尝试创建一个具有待办事项功能的网站！到目前为止，我已经对其进行了编程，因此它可以与一个用户完美配合.但是，当我使用其他用户登录时，仍然可以查看待办事项列表，但我不希望这样做.

I am trying to create a website with a To-do function! So far, I've programmed it so it works perfectly with one user. However, when I log in with a different user, I can still view my to-do list, and I don't want this.

现在，如果我可以使这一特定功能对很多人都可以使用，我将非常高兴.因此此人登录到自己的帐户，创建了自己的列表，/我登录以创建自己的列表.

Now, I'd be very happy if I can make this specific feature useable to lots of people. so this person logs into his account, create his own list / I log in to mine and create my own one.

我搜索了太多的YouTube教程和文章，但没有一个帮助到您:(如果在您这样的编码专家的大力协助下，我可以在这里解决这个问题，那就太好了！

I've searched for so many youtube tutorials and articles, none of them helped :( It'll be awesome if I can solve this here, with lots of help from coding experts like you!

这是与待办事项功能相关的代码

Here's my code that's related to To-do feature

Views.py

def ToDo(request):
    todos = TodoList.objects.all()
    categories = Category.objects.all()
    if request.method == "POST":
        if "taskAdd" in request.POST:
            title = request.POST["description"]
            date = str(request.POST["date"])
            category = request.POST["category_select"]
            content = title + " -- " + date + " " + category
            Todo = TodoList(title=title, content=content, due_date=date, 
                            category=Category.objects.get(name=category))
            Todo.save()
            return redirect("/to_do")
        if "taskDelete" in request.POST:
            print(request.POST)
            checkedlist = request.POST.getlist('checkedbox')
            for todo_id in checkedlist:
                todo = TodoList.objects.get(id=int(todo_id))
                todo.delete()
    return render(request, 'Todolist.html', {"todos": todos, "categories":categories})

models.py

models.py

class TodoList(models.Model):
    title = models.CharField(max_length=250)
    content = models.TextField(blank=True)
    created = models.DateField(default=timezone.now().strftime("%Y-%m-%d"))
    due_date = models.DateField(default=timezone.now().strftime("%Y-%m-%d"))
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

    class Meta:
        ordering = ["-created"]

    def __str__(self):
        return self.title

Todo.html

            <li class="taskItem">
                <input type="checkbox" class="taskCheckbox" name="checkedbox" id="{{ todo.id }}" value="{{ todo.id }}">

                <span class="category-{{ todo.category }}">{{ todo.category }}</span>
                <strong class="taskDate"><i class="fa fa-calendar"></i>{{ todo.created }} - {{ todo.due_date }}</strong>
            </li>
        {% endfor %}
        </ul>
        </form>
        </div>

有人可以帮我具体说明一下用户吗?谢谢！！

Could someone please help me to make this specific to users? Thank you!!

推荐答案

首先，您的TODO模型需要与用户关联

First your TODO model needs to associate to a user

from django.conf import settings

class TodoList(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    title = models.CharField(max_length=250)

创建待办事项时，将其链接到用户

When you create the todo, link it to the user

def ToDo(request):
    ...
    Todo = TodoList(user=request.user, title=title, content=content, due_date=date, 
                            category=Category.objects.get(name=category))
Todo.save()
    ...

检索列表时，需要按用户进行过滤

When you retrieve the list, you need to filter by the user

def ToDo(request):
    todos = ToDo.objects.filter(user=request.user)
    ...
