Question

我正在处理Django应用程序。该应用程序拥有一个表单，填写后将重定向到 item_list 页面，用户可以在其中查看他们发布的项目，也可以删除该项目。我希望此页面仅列出当前登录的特定用户发布的项目。但是，现在，此页面列出每个用户的项目。我尝试在模板中添加if大小写，但这导致不显示任何帖子。我究竟做错了什么？到目前为止，这是我的代码

items_list模板

{% extends 'base.html' %}
{% load staticfiles %}

{% block title %} items {% endblock title %}

{% block header %}
  <link rel="stylesheet" href="{% static 'css/item_list.css' %}">

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script type="text/javascript" src="{% static 'js/item_list.js' %}"></script>
{% endblock header %}

{% block content %}
<div class="container">
  <center><h2>Items</h2></center>
  <table class='table table-borderless table-hover'>
    <thead>
      <tr>
        <th>Image</th>
        <th>Title</th>
        <th>Pattern</th>
        <th>Color</th>
        <th>Vendor</th>
        <th>Upload date</th>
        <th>Time</th>
        <th></th>
        <th></th>
      </tr>
    </thead>
    {% for item in items %}
      {% if request.user == item.vendor %}
      <tr>
        <td>
          <a href="{{item.img.url}}" target="_blank"><img src="{{item.img.url}}" alt="{{item.title}}" style="width:80px;"></a>
        </td>
        <td>{{item.title}}</td>
        <td>{{item.pattern}}</td>
        <td>{{item.color}}</td>
        <td>{{item.vendor}}</td>
        <td>{{item.date}}</td>
        <td>{{item.time}}</td>
        {% endif %}
        <td>
          <a href="{% url 'upload_item' %}" class='btn btn-outline-warning btn-sm text-dark' style="width:100px">Edit item</a>
        </td>
        <td>

          <button class="btn btn-danger btn-sm" data-toggle="modal" data-target="#myModal" style="width:100px">Delete item</button>

          <div class="modal fade" id="myModal" role="dialog">
            <div class="modal-dialog modal-dialog-centered">
              <div class="modal-content">
                <div class="card-header"><center><h5 class="modal-title">Are you sure you want to delete this item?</h5></center></div>
                <div class="modal-body" style="height:200px">
                  <center>
                    <br>
                    <form method="post" action="{% url 'delete_item' item.pk %}" style="margin-top:10%;">
                      {% csrf_token %}
                      <button type='submit' class="btn btn-danger" style="width:200px">Delete item</button>
                      <button type="button" class="btn btn-outline-primary" data-dismiss="modal" style="width:200px">Cancel</button>
                    </form>
                  </center>
                </div>
                <div class="card-footer text-muted">
                  <center>Once an item is deleted, It cannot be retrieved</center>
                </div>
              </div>
            </div>
          </div>

        </td>

我正在尝试根据request.user和item.vendor过滤项目。但这不显示任何项目。

views.py

def upload_item(request):
    if request.method == 'POST':
        form_des = ItemForm(request.POST, request.FILES)

        if form_des.is_valid():
            form_des.save()
            return redirect('item_list')
    else:
        form_des = ItemForm()
        form_des.fields['vendor'].widget.attrs['value'] = request.user
        form_des.fields['vendor'].widget.attrs['readonly'] = True

        return render(request, 'upload_item.html', {'form_des': form_des})

def item_list(request):
    items = Item.objects.all()
    return render(request, 'item_list.html', {'items':items})

在views.py中的upload_item函数下，我已将vendor字段设为只读，并自动填充到发布该项目的用户，以使其无法更改。

我在做什么错？请帮助我

谢谢

您应该在视图中进行过滤：

def item_list(request):
    items = Item.objects.filter(vendor=request.user)
    return render(request, 'item_list.html', {'items':items})

根据Django模板中的特定字段过滤帖子
