'post' object 在 django 中不可迭代，它顯示錯誤，但我沒有得到代碼上的問題

Question

/dashboard 'post' object 處的 TypeError 不可迭代我只是嘗試從 db 表中獲取數據並以 dabel 形式顯示在儀表板上

我的dashboard.html頁面

     {% if posts %}
<table class="table table-dark table-hover">
  <thead>
    <tr>
      <th scope="col" style="width:3%">ID</th>
      <th scope="col" style="width:30%">Title</th>
      <th scope="col" style="width:55%">Description</th>
      <th scope="col" style="width:15%">Action</th>
    </tr>
  </thead>
  <tbody>
    
    {% for post in posts %}
    <tr>
      <td>{{posts.id}} </td>
      <td>{{posts.title}}</td>
      <td>{{posts.desc}}</td>
      <td><a class="btn btn-primary" type="submit" value="Submit">Edit</a>
      <form action ='' , method ='POST' class='d-inline'>
      {% csrf_token %}
      <input type='submit' class='btn btn-danger btn-sm' value ='Delete' >
      </form>
      </td>
    </tr>
    
    {% endfor %}
  </tbody>
</table>
{% else %}
<h4 class =' text-center alert alert-warning'>No Records  </h4>
{% endif %}
</div>
</div>

{% endblock content %}

我的觀點.py

def dashboard(request):
    if request.user.is_authenticated:
        posts= post.objects.all()
        return render(request,'dashboard.html',{'posts':post})
    else:
        return HttpResponseRedirect('login')

網址.py

path('dashboard',views.dashboard,name='dashboard'),

Answer 1

您的views.py文件中有錯字。 嘗試改變這個：

return render(request,'dashboard.html',{'posts':post})
對此：

return render(request,'dashboard.html',{'posts':posts})

Answer 2

我假設在模板 dashboard.html 你必須改變這個：

{% for post in posts %}
<tr>
<td>{{posts.id}} </td>
<td>{{posts.title}}</td>
<td>{{posts.desc}}</td>

對此：

{% for post in posts %}
<tr>
<td>{{post.id}} </td>
<td>{{post.title}}</td>
<td>{{post.desc}}</td>

Answer 3

它應該是這樣的：

 {% for post in posts %} <tr> <td>{{post.id}} </td> <td>{{post.title}}</td> <td>{{post.desc}}</td>
