how can I solve Django TemplateSyntaxError? - python

I suspect it might be due to the version of Django installed automatically by python anywhere, but if you think it's something else, please let me know if I'm missing anything.
Here's the error message populating my page, with the accompanying code issue:
django.template.exceptions.TemplateSyntaxError: Unclosed tag on line 9: 'block'.

Flask generates the wrong template on the page

I am writing a website on Flask, and I encountered a problem that when I send an email with a link to a password recovery page, the http address of which has a token that changes every time, the template that I connected is not generated at all. with completely wrong css styles.
Although the same template is connected in the same way to other pages and everything is fine, what is needed is generated
Here is my view function to handle this page
#app.route('/reset_password/<token>', methods=['POST', 'GET'])
def reset_token(token):
if current_user.is_authenticated:
return redirect(url_for('index_page'))
user = User.verify_reset_token(token)
if user is None:
flash('Неправильний,або застарілий токен', category='error')
return redirect(url_for('reset_password'))
form = ResetPasswordForm()
if form.validate_on_submit():
hash_password = generate_password_hash(form.password.data)
user.password = hash_password
db.session.commit()
return render_template('reset_password.html', title='Відновлення паролю', form=form,
css_link=css_file_reset_password_request_page)
For comparison, here is a function that connects to the same css-style
#app.route('/reset_password', methods=['POST', 'GET'])
def reset_password():
if current_user.is_authenticated:
return redirect(url_for('index_page'))
form = RequestResetForm()
if form.validate_on_submit():
user = User.query.filter_by(email=form.email.data).first()
if user is None:
flash('Неправильний email', category='error')
else:
send_reset_email(user)
flash('Повідомлення було надіслано на вашу електронну пошту,зайдіть туди,щоб отримати '
'інструкції', category='success')
return render_template('reset_password_request.html', title='Відновлення паролю', form=form,
css_link=css_file_reset_password_request_page)
But as a result, these pages have a completely different look
Here is the html template of this page(It is the same as reset_password_request from the previous function, only with some changes)
{% extends 'base.html' %}
{% block body %}
{{ super() }}
{% for cat, msg in get_flashed_messages(True) %}
<div class="flash {{cat}}">{{msg}}</div>
{% endfor %}
<div class="container">
<form class="box" method="POST">
{{ form.hidden_tag() }}
<h1 title="Будь ласка,придумайте новий надійний
пароль">Оновлення паролю</h1>
<div class="group">
<label>{{ form.password.label }}</label>
{{ form.password }}
</div>
<div class="group">

And here is the one that should have been generated, and is generated in the case of the second handler function
Maybe someone knows how to solve it

Flask Jinja2 not rendering bootstrap carousel

I'm wanting to render bootstrap carousel and other nested html elements. im newer to Jinja2 and didn't see anything on the internet talking about this particular issue.
here is my python
#app.route("/")
def index():
r = requests.get(os.environ['AWS_Product_URL'])
prods = list(json.loads(r.text))
return render_template("index.html", my_products=prods)
this works
{% for key in my_products %}
<p><strong>{{ key["name"] }}</strong><span>{{ key["price"] }}</span></p>
{% endfor %}
but this doesn't
{% for key in my_products %}
<div class="carousel-item">
<p><strong>{{ key["name"] }}</strong><span>{{ key["price"] }}</span></p>
</div>
{% endfor %}
I took an existing template and trying to make this dynamic. the class exists. I'm confused why Jinja2 is having trouble with a nested item in html.
Why??
You're probably just missing to add class active to the carousel item
bootstrap carousel items requires at least one active element, all the others will be hidden.
so try out adding something like
{% for key in my_products %}
<div class="carousel-item {% if loop.index == 1 %}active{% endif %}">
<p><strong>{{ key["name"] }}</strong><span>{{ key["price"] }}</span></p>
</div>
{% endfor %}
Just in case, here's template that I've tested with and it should be working fine assuming my_products is not empty.

Django - 'function' object is not iterable - Error during template rendering

So, I've been trying to create a user login. When I click submit on my login form, I get this error:
Exception Type: TypeError
Exception Value: 'function' object is not iterable
Here's the full Traceback: http://dpaste.com/3D1B7MG
So, If I'm reading the Traceback correctly, the problem is in the {% extends "base.html" %} line of all_poss.html. So would that would mean the problem is actually inside base.html? or in the view that controls all_posts?
My all_posts.html

Alright, I was able to solve it.
The problem was apparently in my base.html where I had:
<li>{{ user.username }}</li>
and
<li>Log Out</li>
and I just changed the href="{% %}" tags to "profile/" and "logout/"
respectively.
I ran into this error while doing the Django tutorial.
The core problem was in my app's urls.py, in urlpatterns, with the second argument here:
path('', views.index, views.IndexView.as_view(), name='index'),
It should have been:
path('', views.IndexView.as_view(), name='index'),
Not sure how the extra views.index snuck in there but it was causing the problem. (as to why that exact error occurs - not going to dig too deep)
I believe this is preferable to deleting the {% url '...' id %} call and hard-coding its result as advised in the solution above.

Blank section appear when using Jinja2/Flask

I'm creating a website and it works fine when i use direct html. Now i want to use Jinja2 to render my template and there is something wrong. You can see that there is a blank space on top of my page here http://kgroupman.azurewebsites.net/ but it works fine with firefox. Inspect element do not point out that blank section and there is no padding or margin and there is nothing wrong with the source. Please help!
Here is the code:

It's a character at the top of your body
Solution found. Delete login.html and recreate it. There's must be an invisible character that i can't see somehow!

{Extending templates in django} In my base.html django put all the content of my head tag into my body tag automatically

I'm getting problem with django templates.
my problem come because when I display my website in my browser django put all the content of my head tag into my body tag.
This is my base.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>SecureKids {% block title %}{{title}}{% endblock %}</title>
</head>
<body>
<div id="page-wrapper">
<div class="row">
<div class="col-lg-12">
<h1 class="page-header">{% block apartado %} {% endblock %}</h1>
</div>
<!-- /.col-lg-12 -->
</div>
<!-- /.row -->
<p class="text-success">{% block msg %}{% endblock %}</p>
<div class="row">
{% block contenido %}---{% endblock %}
</div><!-- /.row -->
</div><!-- /#page-wrapper -->
</body>
</html>
and here's a template that extends from base.html
{% extends "base.html" %}
{%load i18n%}
{% block apartado %}
{% trans 'Control Panel' %} <small>{% trans 'Device' %} {{device.name}}</small>
{% endblock %}
{% block contenido %}
<h2>{% trans 'WELLCOME' %}</h2>
<div>
<h3>{% trans 'Child:' %} <small>{{device.child.name}}</small></h3>
<h3>{% trans 'Father's device:' %} <small>{{device.name}}</small></h3>
</div>
{% endblock %}
And this is the result in my browser
<html lang="en">
<head>
</head>
<body>
"
"
<meta charset="utf-8">
<title>SecureKids </title>
<div id="page-wrapper">
<div class="row">
<div class="col-lg-12">
<h1 class="page-header">
Control Panel <small>Device</small>
</h1>
</div>
<!-- /.col-lg-12 -->
</div>
<!-- /.row -->
<p class="text-success"></p>
<div class="row">
<h2>WELLCOME</h2>
<div>
<h3>Child: <small>m</small></h3>
<h3>Father's device: <small>m disp</small></h3>
</div>
</div><!-- /.row -->
</div><!-- /#page-wrapper -->
</body>
</html>
function in views.py for this example
#login_required
def panel(request,oid):
device = get_object_or_404(Device,pk=oid,child__father=request.user.id)
messages.add_message(request, messages.INFO,"Este dispositivo no existe")
return HttpResponseRedirect('/')
request.session["device"] = device.id
request.session["devicen"] = device.name
request.session["childn"] = device.child.name
return render_to_response('children/panel.html',{'device':device},context_instance=RequestContext(request))
As you can see in my browser all the content is into body tag, and django also include 3 empty lines just after body tag
I hope somebody can help me
Thanks
