当用户没有放置自己的图片时,如何为用户设置默认头像?
这是我的模板。
ifequal
声明不起作用。
{% for each_model in Result %}
<div class="panel panel-success" style="margin-left:10px;margin-right:50px ;margin-top:100px;width:400px ;float:right">
<div class="panel-heading">
<h3 class="panel-title"style="text-align:center"><strong>USER INFORMATION</strong></h3>
</div>
<div class="panel-body">
{% ifequal each_model.Profile_image blank %}
<img src="{{MEDIA_URL}}/Profile_image/deafult-profile-image.png"/>
<hr>
{% else %}
<img src="{{MEDIA_URL}}{{each_model.Profile_image}}"style="width:300px; height:200px; display:block; margin-left:auto;margin-right:auto">
<hr>
{% endifequal %}

我试图在字段中输入默认值,但它无效。
class MyUser(AbstractBaseUser):
email = models.EmailField(
verbose_name='Email',
max_length=255,
unique=True,null = False
)
username = models.CharField(max_length = 30, null = False)
Nationality =models.CharField(max_length = 30,choices= Country_choice,null = False )
Mother_language = models.CharField(max_length = 30,choices= Language_list,null = False)
Wish_language =models.CharField(max_length = 30,choices= Language_list,null = False)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
Profile_image = models.ImageField(upload_to='profile_images',blank=True, default= 'profile_images/deafult-profile-image.png')
status_message=models.CharField(max_length = 500,null = True)
objects = MyUserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username','Nationality','Mother_language','Wish_language','Profile_image','status_message']
答案 0 :(得分:1)
请尝试以下操作:
getAttribute()
但我建议您为您的用户模型设置一个方法,该方法将返回用户头像并在模板中使用该方法:
{% if not each_model.Profile_image %}
<img src="{{MEDIA_URL}}/Profile_image/deafult-profile-image.png"/>
<hr>
{% else %}
<img src="{{MEDIA_URL}}{{each_model.Profile_image}}"style="width:300px; height:200px; display:block; margin-left:auto;margin-right:auto">
<hr>
{% endifequal %}
