Question

我有以下情况：项目可以属于多个部门，员工被分配到多个项目的角色。如何在模板中显示角色字段？ employees.role显示空白......

模型

class Projects(models.Model):
    name = models.CharField(max_length=20)

class Department(models.Model):
    name = models.CharField(max_length=20)

class Employees(models.Model):
    fname = models.CharField(max_length=15)

class Departmentprojects(models.Model):
    department = models.ForeignKey(Department)
    projects = models.ForeignKey(Projects)
    members = models.ManyToManyField(Employee, through='Membership')

class Membership(models.Model):
    departmentprojects = models.ForeignKey(Departmentprojects)
    employee = models.ForeignKey(Employee)
    role = models.CharField(max_length=20) #i want to show this field in a template

查看

def department_detail(request, company_id):
department = get_object_or_404(Department, pk=department_id)
return render_to_response('test/detail.html', {'department': department})

TEMPLATE

<h1>{{ department.name }}</h1>

{% for projects in department.departmentprojects_set.all %}
    <h2>{{ projects.projects }}</h2>
        <ul>
            {% for employees in projects.members.all %}
                <li>{{ employee }} | {{ employee.role }}</li>
            {% endfor %}
        </ul>
{% endfor %}

Answer 1

迭代“直通”模型而不是目标模型：

{% for membership in projects.membership_set.all %}
<li>
   {{ membership.employee }} | {{ membership.role }}
</li>
{% endfor %}
