Question

这个if语句有什么用吗？它工作，只是不正确。没有出现错误，它会显示与每个单词值相关联的数字，但不会显示正确的单词和前端。

<p class="accent list-text">I'm a:</p>
{% if request.user.userprofile.user_type == 1 %}
    <p class="profile-info list-text">Designer</p>
{% elif request.user.userprofile.user_type == 2 %}
    <p class="profile-info list-text">Designer</p>
{% else %}
    <p class="profile-info list-text">Both</p>
{% endif %}

Models.py：

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from users.choices import *
from django.db.models.signals import post_save
from django.dispatch import receiver

# Create your models here.
class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)

    first_name = models.CharField(max_length=50,default='User')
    join_date = models.DateTimeField(default=timezone.now)
    profile_pic = models.ImageField(upload_to='profile_pics',null=True,blank=True)
    location = models.CharField(max_length=150)
    title = models.CharField(max_length=250)
    user_type = models.IntegerField(choices=USER_TYPE_CHOICES,default=1)
    website = models.URLField(max_length=100,blank=True)
    about = models.TextField(max_length=500,default='about')
    twitter = models.CharField(max_length=50,blank=True)
    dribbble = models.CharField(max_length=50,blank=True)
    github = models.CharField(max_length=50,blank=True)

    @receiver(post_save, sender=User)
    def create_user_profile(sender, instance, created, **kwargs):
        if created:
            UserProfile.objects.create(user=instance)

    @receiver(post_save, sender=User)
    def save_user_profile(sender, instance, **kwargs):
        instance.userprofile.save()

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

choices.py：

USER_TYPE_CHOICES = (
    (1, ("Designer")),
    (2, ("Developer")),
    (3, ("Both")),
)

Answer 1

在 UserProfile模型

中

只需使用CharField进行此类选择即可。

USER_TYPE_CHOICES = (
    ('1', 'Designer'),
    ('2', 'Developer'),
    ('3', 'Both'),
)

user_type = models.CharField(max_length=1,choices=USER_TYPE_CHOICES,default='1')

我的模板标签不太对劲
