我正在尝试在django模板中添加个人资料图片,以便为帖子添加评论...如果模型中没有个人资料图片,那么我想用带样式的文本代替Image。但是我担心如何告诉django模板是否存在图像...
<div class="comment-author">
{% for image in profile %}
{% if image.profile|slugify == comment.author %}
{% with "exist" as img %} <!-- if image exist create img variable -->
<img src="{{ image.profileImg.url }}" alt="{{ image.profile }}">
{% endif %}
{% endfor %}
{% if not img %} <!-- using img variable for checking -->
<span class="userImg"><b>{{ comment.author|make_list|slice:':2'|join:'' }}</b></span>
{% endif %}
{% endwith %} <!-- closing the with statement -->
在上面的代码中,我尝试使用'with'创建变量img,但模板中出现错误...该怎么办?

模板标记未正确关闭。另请参阅docs,改进代码。
<div class="comment-author">
{% for image in profile %}
{% if image.profile|slugify == comment.author %}
{% with "exist" as img %} <!-- if image exist create img variable -->
<img src="{{ image.profileImg.url }}" alt="{{ image.profile }}">
{% else %} <!-- using img variable for checking -->
<span class="userImg"><b>{{ comment.author|make_list|slice:':2'|join:'' }}</b></span>
{% endif %}
{% endwith %} <!-- closing the with statement -->
{% endfor %}
