The If equal not working in Django Template

Question

I am able to fetch these two values in the Django HTML template :

{{ post.user }}

But when I use them further to compare their values in an IF condition, it doesn't work.

 {%for post in post%}
              <a href="{% url 'post_detail' post.id %}"><h1>{{post.title}}</h1></a>
              <h2>{{post.content}}</h2>
              <p>{{post.date}}</p>
                {%if user.is_authenticated%}
                  <h3> {{ user.get_username }}</h3>
                  <h3> {{post.user}} </h3>
                    {%ifequal user.get_username post.user%}
                      <form action="{%url 'post_delete' post.id %}" method="POST">
                        {%csrf_token%}
                        <button type="submit">Delete</button>
                      </form>
                    {%endifequal%}
                {%endif%}
            {%endfor%}

I've also tried {% if user.get_username == post.user %} as well, but it didn't help either.

Please help. I need the delete button only against the posts of logged in user.

It's showing the Post Title and Post Content of all the posts. That's it. But no delete button, even though the user is logged in. — Karan Kumar, Mar 31 '20 at 16:54
Can it be so that both values are equal but there is difference between the case of some characters? Some are lower case and some are upper case? — Moosa Saadat, Mar 31 '20 at 16:58
They're exactly the same when I render them like this in the template: {{ user.get_username }} {{ post.user }} — Karan Kumar, Mar 31 '20 at 16:59
Try `{% if user == post.user %}`. Ifequal is obsolete, you should use the regular if tag. — Alasdair, Mar 31 '20 at 17:00

{{ user.get_username }} and {{ post.user }} are different objects.

If you want to compare the "string" representation of both (thats what you see in the rendered template), you have to convert {{ post.user }} to a string. (I'd convert them both, since I don't know if you user_name is also a string (it should be, though). Use:

{% if user.get_username|stringformat:'s' == post.user|stringformat:'s' %}

Check documentation here:

Django Template Tag: Stringformat

Python Conversion Types (I.e. 's')

This doesn't work and gives an error 'invalid filter string()' – Karan Kumar Mar 31 '20 at 17:21
This would only work if the OP was using Jinja templates. Even if they were, it would be simpler to use `{% if user == post.user %}` – Alasdair Apr 02 '20 at 18:43

{% if user == post.user %} worked for me. Looks like 'user.get_username' was not working. Just 'user' worked. I wonder why though.

`user.get_username()` returns a string. `user` is a `User` instance. They are not the same types, so they are not equal, even though `{{ user }}` displays the same string in the template. – Alasdair Mar 31 '20 at 17:49

{% if notification.status|stringformat:'s' == 'Approved' %} <td><div class="badge badge-success">{{ notification.status }}</div></td> {% else %} <td>{{ notification.status }}</td> `{% endif %}'
