TemplateDoesNotExist at /users/register/ bootstrap5/uni_form.html

I am building a registration form for my django project, and for styling it I am using crispy forms. But, when I run my server and go to my registration page, I see this error:

    Internal Server Error: /users/register/
Traceback (most recent call last):

    raise TemplateDoesNotExist(template_name, chain=chain)

The above exception was the direct cause of the following exception:

django.template.exceptions.TemplateDoesNotExist: bootstrap5/uni_form.html

This doesn’t look like the usual TemplateDoesNotExistError I get. I think this is the error in my crispy form, because if I remove the crispy template tags in my form, everything works fine.

Here is my register template:

{% extends 'base.html' %}
{% load crispy_forms_tags %}

{% block title %}Register{% endblock %}

{% block content %}
<h1>Sign up for a new account</h1>
<hr>
<form action="" method="post">
    {% csrf_token %}
    {{ form|crispy }}
    <button type="submit" class="btn btn-sm btn-primary">Register</button>
</form>
<p>
    Already have an account?
    <a href="#">Log in</a>
</p>
{% endblock %}

And just in case it is required, here is my view function:

def register(request):
    form = RegistrationForm()

    if request.method == 'POST':
        form = RegistrationForm(data=request.POST)
        if form.is_valid():
            form.save()
            return HttpResponse("Successfully Registered!!!")

    context = {
        'form':form,
    }
    return render(request, 'users/register.html',context)

I have specefied CRISPY_TEMPLATE_PACK in my settings.py and also added crispy_forms to my INSTALLED_APPS. Where am I going wrong?

EDIT:

So I did a bit more research on this topic and this error is probably because crispy forms does not support bootstrap 5 yet. So, by changing the bootstrap5 to bootstrap4 in my CRISPY_TEMPLATE_PACK, the error is solved

Answer

Based on the latest crispy form doc, it seems that there is no built-in bootstrap5 for it. Are you sure you are using bootstrap5?

Currently, there are only bootstrap, bootstrap3, bootstrap4, and uni-form.

You can take a look at your file structure if you even see bootstrap5 folder.
