如何在Django模板中声明变量并在if条件下更改该变量的值？

Question

I'm trying to add a profile image in django template for comments for the post... If profile image is not there in the model then I want to replace with the styled text in place of Image. But I'm getting worried about how to tell the django template that if image exists or not...

<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 -->

In the above code I have tried to create a variable img using 'with' but getting error in template... What should I do with this?

Template tags are not closing properly. Please refer to docs Also, improved code a bit.

<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 %}
