Html content not showing up after if statement in Django

Im having some issues with my html content not showing up after putting in some {% if %} {% endif %} statements in my templates
I have this snippet in my code where I display the checkout table if and only if the current user's username matches the one from my Order model. (order.customer_name has a foreign key that is set to the current users username)
{% for order in latest_order %}
{% if user.username == order.customer_name %}
<tr>
<td>{{ order.order_name }}</td>
<td>
<form method="post">
{% csrf_token %}
<button type="submit" name="remove_quantity" value="{{ order.id }}" class="mr-3 btn
btn-outline-info">-</button>
{{ order.order_quantity }}
<button type="submit" name="add_quantity" value="{{ order.id }}" class="ml-3 btn btn-
outline-info">+</button>
</form>
</td>
<td>${{ order.order_individual_price }}</td>
<form method="post">
{% csrf_token %}
<th><button type="submit" name="delete" value="{{ order.id }}" class="btn btn-
danger">Delete Item</button></th>
</form>
</tr>
{% endif %}
{% endfor %}`
I tried the following to see if it prints out the same username, which it does
<h1>{{ user.username }}</h1>
{% for order in latest_order %}
<h1>{{ order.customer_name }}</h1>
{% endfor %}
Picture of the page with user.username and order.customername as h1
When I delete the if statement, this is what the website SHOULD look like
Proper working table
Im pretty sure I'm missing something very obvious, Any help is appreciated!

Custom widget for a RadioField Wtforms used inside a Flask app not set CHECKED

I have a problem on a custom widget for a RadioField Wtforms used inside a Flask app.
The custom widget is rendered well, but it DOES NOT WORK because it does not set the "checked" on the field after choosing it. If instead I use the default widget everything is fine and it works.
I also tried another more standard way, that is the "real" custom widget called inside the form class definition ... but I have the exact same result.
Below is the code, any suggestions? Thanks :-)
#### ROUTE
bp = Blueprint('auth', __name__, url_prefix='/auth')
#bp.route('/generic_crud', methods=('GET', 'POST'))
#login_required
def generic_crud():
form = forms.BaseGenericForm()
if form.validate_on_submit():
# Insert the msg
models.BaseGenericFormTable.add_record( title_select = form.titleSelect.data,
title_radio = form.titleRadio.data,
title_checkbox = form.titleCheckbox.data )
return render_template('sample_wtforms/success.html')
return render_template('sample_wtforms/crud_generic.html', form=form)

For a custom widget I do:
<div id="{{ field.id }}">
{{ field.label(class="form-label") }}<br>
{% for subfield in field %}
<div class="form-check form-check-inline">
<input {% if subfield.checked %}checked {% endif %}type="radio" class="form-check-input" id="{{ subfield.id }}" name="{{ field.id }}" value="{{ subfield.id[-1] }}">
{{ subfield.label(class="form-check-label") }}
</div>
{% endfor %}
</div>
The relevant part for you should be "{% if subfield.checked %}checked {% endif %}"

How to populate table after button click in django template?

1) I want to insert the values in the input field from the dictionary using DTL.
Here's the snippet of code that on load page, making invisible this code tag in the table (may be because of if condition turns False) but just after data submission from dictionary, showing inserted value in the same tag.
How can I make it work and remains all the td tags visible on the page load as well?
2) Also since my data.items having 6 keys, so its iterating 6 times, I just want to get single time.
I know I'm not very clear but sorry I can't post the whole code since is too big and confidential.
Please Help it out, I'm totally new in django. Thanks.
....
...
..
{% for key, value in data.items %}
{% for key2,value2 in value.items %}
<tr class="info">
<td>1</td>
<td>Cholesterol -HDL</td>
<td>
{% if value2.test_name == "Cholesterol -HDL" %}
<div class="form-group">
<input type="text" class="form-control" name="cholesterol_hdl_result" value="{{ value2.results }}">
</div>
</td>
<td><div class="form-group">
<input type="text" class="form-control" name="cholesterol_hdl_uom" value="{{ value2.units }}">
</div></td>
<td><div class="form-group">
<input type="text" class="form-control" value="40.00" name="cholesterol_hdl_lr">
</div></td>
<td><div class="form-group">
<input type="text" class="form-control" value="60.00" name="cholesterol_hdl_hr">
</div></td>
{% endif %}
</tr>
{% endfor %}
{% endfor %}
..
...
....

So, when the dictionary is empty you have to check that in if and else condition and write that <td> tag in else block as below...
{% if data %}
......
......
{% for key, value in data.items %}
{% for key2,value2 in value.items %}
....
....
{% endfor %}
{% endfor %}
{% else %}
# write your default <td> tag here which is shown when there is empty data dictionary
{% endif %}
And for iterate for loop only once you have to use forloop.first of django template as below...
{% for key, value in data.items %}
{% if forloop.first %}
{% for key2,value2 in value.items %}
....
....
{% endfor %}
{% endif %}
{% endfor %}

Django-userena showing forms twice when using with Crispy Forms

I am trying to use Crispy forms with Django-userena to make it look better but when ever I put the Crispy form tags in it duplicates the form,
My code is as followed:
{% extends 'userena/base_userena.html' %}
{% load i18n %}
{% load url from future %}
{% load crispy_forms_tags %}
{% block title %}{% trans "Signin" %}{% endblock %}
{% block content %}
<form action="" method="post" class="formholder">
{% csrf_token %}
{{ form|crispy }}
<fieldset>
<legend>{% trans "Signin" %}</legend>
{{ form.non_field_errors }}
{% for field in form %}
{{ field.errors }}
{% comment %} Displaying checkboxes differently {% endcomment %}
{% if field.name == 'remember_me' %}
<p class="checkbox">
<label for="id_{{ field.name }}">{{ field }} {{ field.label }}</label>
</p>
{% else %}
<p>
{{ field.label_tag }}
{{ field }}
</p>
{% endif %}
{% endfor %}
</fieldset>
<input type="submit" value="{% trans "Signin" %}" />
<p class="forgot-password">{% trans "Forgot your password?" %}</p>
{% if next %}<input type="hidden" name="next" value="{{ next }}" />{% endif %}
</form>
{% endblock %}

Solution by OP.
The problem was that the, {{ form|crispy }} was actually creating the form in the form.py file all I had to do was remove all the other from tags and just keep the {{ form|crispy }}
Here is what it looks like:
{% extends 'userena/base_userena.html' %}
{% load i18n %}
{% load url from future %}
{% block title %}{% trans "Signin" %}{% endblock %}
{% block content %}
{% load crispy_forms_tags %}
<form action="" method="post" class="formholder">
{% csrf_token %}
<fieldset>
<legend>{% trans "Signin" %}</legend>
{{ form|crispy }}
</fieldset>
<input type="submit" value="{% trans "Signin" %}" />
<p class="forgot-password">{% trans "Forgot your password?" %}</p>
{% if next %}<input type="hidden" name="next" value="{{ next }}" />{% endif %}
</div>
</form>
{% endblock %}
