Question

当管理员登录要编辑的页面时，我正在尝试编辑特定用户的用户详细信息，但是当我按下更新按钮时，它没有更新，没有显示任何错误消息。（如果我写错了请指正）。
这是我的edit.html

{% extends 'base.html' %}
{% block title %}edit details{% endblock %}
{% block content %}
{% if emp %}
<form method="POST" class="form-inline my-2 my-lg-0" ">  
    {% csrf_token %}  
<div class="container">  
<br>  
<div class="form-group row">  
<label class="col-sm-1 col-form-label"></label>  
<div class="col-sm-4">  
<h3>Update Details</h3>  
 </div>  
</div>  
<div class="form-group row">  
<label class="col-sm-2 col-form-label">Employee User:</label>  
<div class="col-sm-4">  
    <input type="text"  id="id_user" required maxlength="20" value="{{ 
  emp.user }}"/>  
  </div>  
</div>  
<div class="form-group row">

<div class="col-sm-4">  
    <input type="search"  id="id_first_name" required maxlength="100" 
  value="{{ emp.first_name }}" />  
  </div>  
</div>
<div class="form-group row">

  value="{{ emp.salary }}" />
 </div>  
</div>    
<div class="form-group row">  
<label class="col-sm-1 col-form-label"></label>  
<div class="col-sm-4">  
<button type="submit" class="btn btn-success">Update</button>  
  </div>  
</div>  
</div>  
</form>
{% endif %}  
{% endblock %}

这是我的profile.html页面

{% if user.is_authenticated %}
 {% if user.is_superuser %}
<table class="table table-striped table-bordered table-sm">  
  <thead class="thead-dark">  
  <tr>  
    <th>Employee User</th>  
    <th>Employee first_name</th>  
    <th>Employee last_name</th>  
    <th>Employee Email</th>
    <th>Employee Gender</th>
    <th>Employee Age</th>
    <th>Employee Salary</th>        
    <th>Actions</th>  
 </tr>  
 </thead>  
<tbody>  
 {% for employee in employees %}  
 <tr>  
    <td>{{ employee.user }}</td>  
    <td>{{ employee.first_name }}</td>  
    <td>{{ employee.last_name }}</td>  
    <td>{{ employee.email }}</td>
    <td>{{ employee.gender }}</td>
    <td>{{ employee.age }}</td>
    <td>{{ employee.salary }}</td>  
    <td>  
        <a href="{% url 'edit' employee.id %}"><span class="glyphicon 
        glyphicon-pencil" >Edit</span></a>  
        <a href="/delete/{{ employee.id }}">Delete</a>  
    </td>  
 </tr>  
{% endfor %}  
</tbody>  
</table>  
<br>  
<br>  
<center><a href="{% url 'signup' %}" class="btn btn-primary">Add New 
  Record</a></center>
 {% else %}
<p>username : {{ user }}</p>
<p>firstname : {{ user.first_name }}</p>
<p>lastname : {{ user.last_name }}</p>
<p>{{user.employee.age}}</p>
<p>
<a href="{% url 'edit_profile' %}">Edit details</a>
</p>
<p>
<a href="{% url 'change_password' %}">Change password</a>
</p>
{% endif %}
{% endif %}

这是编辑方法的view.py

def edit(request, emp_id):
    if request.method == 'POST':
        emp = employee.objects.get(pk=emp_id)
        form = EmployeForm(request.POST or None, instance=emp)

        if form.is_valid():
            form.save()
            messages.success(request, ('Item has been edited'))
            return HttpResponseRedirect('view_profile')
    else:
        emp = employee.objects.get(pk=emp_id)
    return render(request, 'edit.html', {'emp': emp})

def view_profile(request):
    employees = employee.objects.all()    
    args= {'user':request.user,'employees':employees}
    return render(request,'profile.html',args)

这是我的模型页面

class employee(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    email = models.EmailField(max_length=50)
    gender = models.CharField(max_length=1,choices=(('M','Male'), 
     ('F','Female')),blank=True)
    age = models.PositiveIntegerField(blank=True, null=True)
    salary = models.CharField(blank = True,max_length=50

def __str__(self):
    return self.user.username

请提供有关如何进行故障排除的建议或我可以阅读的任何文档。

您没有正确使用表格。表单不仅用于验证，而且还负责呈现错误消息。您想要更改视图以将表单传递给模板：

def edit(request, emp_id):
    emp = employee.objects.get(pk=emp_id)
    if request.method == 'POST':
        form = EmployeForm(request.POST, instance=emp)
        if form.is_valid():
            form.save()
            messages.success(request, ('Item has been edited'))
            # this one is probably not going to work
            # as expected - you may want to check the
            # doc for the `redirect` shortcut instead
            return HttpResponseRedirect('view_profile')
    else:
        form = EmployeForm(instance=emp)

    return render(request, 'edit.html', {'emp': emp, 'form':form})

然后在您的模板中，而不是手动编写整个表单标记use the form for rendering，以便正确显示验证错误。
