Django 'endfor', expected 'endblock'

I am attempting to learn Django but keep receiving the error " 'endfor', expected 'endblock'. Did you forget to register or load this tag? " when I add the {% for key,value in
price.DISPLAY.items %} {{ key }} {% endfor %} part of the code. How can I fix this? Any help would be great thanks.
home.html
{% extends 'base.html' %} {% block content %} {% for key,value in
price.DISPLAY.items %} {{ key }} {% endfor %}
<br />
<br />
{{ price.DISPLAY }}
<div class="jumbotron">
<h1 class="display-4">Welcome</h1>
</div>
<div class="container">
<div class="row">
{% for info in api.Data %}
<div class="card" style="width: 18rem">
<img src="{{info.imageurl}}" class="card-img-top" alt="{{info.source}}" />
<div class="card-body">
<h5 class="card-title">{{info.title}}</h5>
<p class="card-text">{{info.body}}</p>
<a href="{{info.url}}" class="btn btn-secondary" target="_blank"
>Read more</a
>
</div>
</div>
{% endfor %}
</div>
</div>
{{ api.Data }} {% endblock content %}

A template tag should not span multiple lines. You should write the {% for … %} tag on a single line:
{% extends 'base.html' %} {% block content %}
{% for key,value in price.DISPLAY.items %} {{ key }} {% endfor %}
…
{% endblock content %}

Is it possible to custom django-tables2 template for a specific page in this case?

I'm using django-tables2 to render my data in tables in the template..
everything is rendered fine with pagination..
The Designer of our company wants to change the Display of data into blocks instead of simple table. the following picture may explain more.
I Want to ask if I can use Django tables2 in this case ..since I don't want to loose the pagination
Is it possible to custom the django_tables2/table.html file to only fit this case (because I'm using django-tables2 in many other pages in the project)?
Any other ideas may be helpful.
Thanks in advance :)

Yes, you can create a custom template (based on django_tables2/table.html) and set a specific table's template Meta attribute to its path:
import django_tables2 as tables
class Table(tables.Table):
# columns
class Meta:
template = 'table-blocks.html'
or use the template argument to the Table constructor:
table = Table(queryset, template='table-blocks.html')
or use the second argument of the {% render_table %} templatetag:
{% load django_tables2 %}
{% render_table queryset 'table-blocks.html' %}

I was having the same requirement and i had been able to do it. To achieve the desired results i have used bootstrap4 and modified the "django_tables2/bootstrap4.html" template. My modified template only displays blocks which can further be enhanced by embedding more css in it.
{% load django_tables2 %}
{% load i18n %}
{% block table-wrapper %}
<div class="container-fluid relative animatedParent animateOnce p-0" >
{% block table %}
{% block table.tbody %}
<div class="row no-gutters">
<div class="col-md-12">
<div class="pl-3 pr-3 my-3">
<div class="row">
{% for row in table.paginated_rows %}
{% block table.tbody.row %}
<div class="col-md-6 col-lg-3 my-3">
<div class="card r-0 no-b shadow2">
{% for column, cell in row.items %}
<div class="d-flex align-items-center justify-content-between">
<div class="card-body text-center p-5">
{% if column.localize == None %}{{ cell }}{% else %}{% if column.localize %}{{ cell|localize }}{% else %}{{ cell|unlocalize }}{% endif %}{% endif %}
</div>
</div>
{% endfor %}
</div>
</div>
{% endblock table.tbody.row %}
{% empty %}
{% if table.empty_text %}
{% block table.tbody.empty_text %}
<tr><td colspan="{{ table.columns|length }}">{{ table.empty_text }}</td></tr>
{% endblock table.tbody.empty_text %}
{% endif %}
{% endfor %}
</div></div></div> </div>
{% endblock table.tbody %}
{% block table.tfoot %}
{% if table.has_footer %}
<tfoot {{ table.attrs.tfoot.as_html }}>
<tr>
{% for column in table.columns %}
<td {{ column.attrs.tf.as_html }}>{{ column.footer }}</td>
{% endfor %}
</tr>
</tfoot>
{% endif %}
{% endblock table.tfoot %}
{% endblock table %}
</div>
{% block pagination %}
{% if table.page and table.paginator.num_pages > 1 %}
<nav aria-label="Table navigation">
<ul class="pagination justify-content-center">
{% if table.page.has_previous %}
{% block pagination.previous %}
<li class="previous page-item">
<a href="{% querystring table.prefixed_page_field=table.page.previous_page_number %}" class="page-link">
<span aria-hidden="true">«</span>
{% trans 'previous' %}
</a>
</li>
{% endblock pagination.previous %}
{% endif %}
{% if table.page.has_previous or table.page.has_next %}
{% block pagination.range %}
{% for p in table.page|table_page_range:table.paginator %}
<li class="page-item{% if table.page.number == p %} active{% endif %}">
<a class="page-link" {% if p != '...' %}href="{% querystring table.prefixed_page_field=p %}"{% endif %}>
{{ p }}
</a>
</li>
{% endfor %}
{% endblock pagination.range %}
{% endif %}
{% if table.page.has_next %}
{% block pagination.next %}
<li class="next page-item">
<a href="{% querystring table.prefixed_page_field=table.page.next_page_number %}" class="page-link">
{% trans 'next' %}
<span aria-hidden="true">»</span>
</a>
</li>
{% endblock pagination.next %}
{% endif %}
</ul>
</nav>
{% endif %}
{% endblock pagination %}
{% endblock table-wrapper %}

Error in the template with Django : can I make arithmetic in if statement

I would like to make a pagination with Bootstrap : a new page every 10 new field in data.
file.html
{% for d in data %}
{% if forloop.first %}
<ul class="pagination">
{% endif %}
{% if (forloop.counter % 10) == 0 %}
<li>{{ forloop.counter % 10 }}</li>
{% endif %}
{% if forloop.last %}
</ul>
{% endif %}
{% endfor %}
output I would like that => Bootstrap pagination
But Django give me an error for this :
{% if (forloop.counter % 10) == 0 %}
TemplateSyntaxError :/
I don't know how to do except create my own filter or add a filter, but i would like to know first if i can do in the template first.
PS: I use Django 1.5 and I can't upgrade it.
Edit:
Finally I use this condition:
{% if forloop.counter|divisibleby:'10' and forloop.counter|divisibleby:'5' and forloop.counter|divisibleby:'2' %}
Like that I know when I have a 10 multiple.

The modulus (%) operator is not available in django templates. However, you can use the divisibleby (https://docs.djangoproject.com/en/1.5/ref/templates/builtins/#divisibleby) template filter, something like
{% if forloop.counter|divisibleby:"2" %}

Use the paginator, your QuerySet are not evaluated for the hole table, just the number you need to build the page, and it offers properties that you can use in the template like (page_range, next_page_number, has_next, etc.)
here is the code withe BootStrap 2 and django.core.paginator:
<div class="pagination pagination-centered">
<ul>
{% if MYDATAENTIRES.has_previous %}
<li>
{% trans "Précédent" %}
</li>
{% endif %}
{% for i in MYDATAENTIRES.paginator.page_range %}
<li {% ifequal MYDATAENTIRES.number i %} {{ 'class="disabled"' }} {% endifequal %}>
<a href="?page={{ i }}">
{{ i }}
</a>
</li>
{% endfor %}
{% if MYDATAENTIRES.has_next %}
<li>
{% trans "Suivant" %}
</li>
{% endif %}
</ul>
</div>

Django {% if forloop.first %} question

I have the following code in my template:
{% for object in object_list %}
{% with game=object.game %}
{% for category in object.game.objectmeta.categories.all %}
{% if category.name|title == 'Puzzle' %}
{% if forloop.first %}
<div class='side_header' id='dark_gamelink_side'>
<a class='actionheader' href=""></a>
</div>
{% endif %}
<div class='game_link' id='dark_gamelink'>
<a class='img_link' href="{% url game_view game.id game.title|slugify %}">
<img class='game_img' src='{{game|thumb:"78x65"}}' alt='{{game.title}}' />
</a>
<div class='top_game_title' style='padding:0'>
<a style='position:relative; top:-3px' id='yellowlink' href="{% url game_view game.id game.title|slugify %}">{{game.title}} -- {{category.name|title}}</a>
<img style='position:relative; top:1px; margin-left:12px' src='thumbsup.gif' width='17' height='18'/>
<span style='position:relative; top:-3px; font-size:10px; color:white'>99%</span>
</div>
{% if game.description|length > 65 %}
{{ game.description|slice:"65" }}...
{% else %}
{{ game.description }}
{% endif %}
</div>
{% if forloop.counter0 == 3 %}
<div class='more_games'><br/></div><div class='side_header' id='dark_gamelink_side'><a class='adventureheader' href=adventure.htm></a></div>
{% endif %}
{% endif %}
{%endfor%}
{% endwith %}
{% endfor %}
Now I'm using this:
{% if forloop.first %}
<div class='side_header' id='dark_gamelink_side'>
<a class='actionheader' href=""></a>
</div>
{% endif %}
to try to detect if this is the first iteration of the for loop immediately preceding it not the parent forloop. In other words I'm trying to detect if it's the 1st iteration of this for loop:
{% for category in object.game.objectmeta.categories.all %}
not this one:
{% for object in object_list %}
The way it is now isn't working because it's displaying this:
<div class='side_header' id='dark_gamelink_side'>
<a class='actionheader' href=""></a>
</div>
Twice. How to detect the first iteration of the nested forloop?

Edited:
I have never used these variables but I think forloop.parentloop.first should do it. If not blame me to have misunderstand the Django docs. ;-)
You should check if you are within the parentloop and and then within the first nested node. Please try this modified template. It should you give the right direction.
{% if forloop.parentloop.first %}
I am in the first loop of the parent
{% else %}
{% if forloop.first %}
<div class='side_header' id='dark_gamelink_side'>
<a class='actionheader' href=""></a>
</div>
{% endif %}
{% endif %}

I think the best way to solve this isn't to detect if this is the first iteration in the loop, but rather to write your HTML so that is outside the loop entirely.
You should only be writing HTML elements in the for loop that you actually want repeated for each iteration. If that doesn't work, rethink how you're providing the data to your view (object_list, game, category, etc) so that you can write your markup more easily.
The beginning of your view will probably look something like this:
<div class='side_header' id='dark_gamelink_side'>
<a class='actionheader' href=""></a>
</div>
{% for object in object_list %}
{% with game=object.game %}
{% for category in object.game.objectmeta.categories.all %}
{% if category.name|title == 'Puzzle' %}

django "load comment"s not working correctly

I am trying to implement a comment section on my app that keeps track of bookmarks.
This is the output that I got when I ran my local host server. It is not what I expected and I can't find out what's wrong. I expected there to be a comment form, a number for the comment count, and a comment list. But the webpage just rendered my code.
This is the code
{% extends "base.html" %}
{% load comments %}
{% block title %}Bookmark:
{{ shared_bookmark.bookmark.title|escape }}{% endblock %}
{% block head %}
<h2> Comments</h2>
{% get_comment_count for bookmarks.sharedbookmark
shared_bookmark.id as comment_count %}
{% get_comment_list for bookmarks.sharedbookmark
shared_bookmark.id as comment_list %}
{% for comment in comment_list %}
<div class="comment">
<p><b>{{ comment.user.username }}</b> said:</p>
{{ comment.comment|escape|urlizetrunc:40|linebreaks }}
</div>
{% endfor %}
<p>Number of comments: {{ comment_count }}</p>
{% comment_form for bookmarks.sharedbookmark
shared_bookmark.id %}
{% endblock %}
Thanks for your help!
