如何使用foreignKey？

请使用foreignKey帮助检索和显示数据

class Gender(models.Model):     
    gender = models.CharField(
        max_length=10, 
        blank=False,
    )   

class UserProfile(User):
    name1 = models.CharField(
        'Имя',
        max_length=30, 
        blank=True,
        null=True,
    )
    gender = models.ForeignKey(
        Gender,
        default=0,
    )

灯具：

[
    {
        "model": "drummersaransk.Gender",
        "pk": 1,
        "fields": {
            "gender": "none"
        }
    },
    {
        "model": "drummersaransk.Gender",
        "pk": 2,
        "fields": {
            "gender": "male"
        }
    },
    {
        "model": "drummersaransk.Gender",
        "pk": 3,
        "fields": {
        "gender": "female"
        }
    }   
]

views.py:

def user_personal(request, id):     
    entries_user_profile = UserProfile.objects.get(user_ptr_id=id)          

    t = loader.get_template('user_personal.html')
    c = RequestContext(request, {
        'entries_user_profile': entries_user_profile,
    })  
    return HttpResponse(t.render(c))

user_personal.html：

{% if entries_user_profile.gender_id %}
    <tr>
        <td class="label">Пол</td>

        <td class="gender info">{{ entries_user_profile.gender_id }}</td>
    </tr>
{% endif %}

问题在于性别不是表性别（无，男性或女性）的输出值

Answer 1

你出gender.id，而不是性别名称。

尝试替换此

<td class="gender info">{{ entries_user_profile.gender_id }}</td>

用这个

<td class="gender info">{{ entries_user_profile.gender.gender }}</td>

也许choices是存储用户性别的更好方法。看看：https://docs.djangoproject.com/en/dev/ref/models/fields/#choices
