How to make to display the button which I need in my template Django? - django-templates

Question

I need:
1) If a user has created a object of the class by a form, then he sees the button which calls the webpage of the object detail.
2) If a user didn't create a object of the class, but another user did it, then he sees the button which calls this form to create a object and the user will be a author this object.
3) If a user didn't create a object of the class by a form, then he sees the button which calls this form.
If a user didn't create a object of the class, but another user did it, then he sees the button which calls this form to create a object and the user will be a author this object.
I made this:
{% if list %}
{% for i in list %}
{% if request.user == i.author %}
<a class="btn" href="{% url 'detail' i.id %}" role="button">
{{i.detail}}
</a>
{% else %}
<button type="button" class="btn" data-toggle="modal" data-target="#form">
the form button
</button>
{% endif %}
{% endfor %}
</div>
{% else %}
<button type="button" class="btn btn-primary mr-4" data-toggle="modal" data-target="#digital">
Кнопка для вызова формы
</button>
{% endif %}
But if a user created a object of the class, then he sees both button.
