Django: TemplateSyntaxError-Could not parse the remainder

My template gets a queryset named qs.value sent from the views.py, I can display the value using {{qs.value}} anywhere in the template, but using it in an if statement raises an error.
{% if {{qs.value}} > 0 %}
<!--do something-->
<h3 class="text-success">{{qs.value}}</h3>
{% else %}
<!--do something else-->
<button class="btn btn-primary">Else</button>
{% endif %}
The error:
Could not parse the remainder: '{{qs.value}}' from '{{qs.value}}'
What am I doing wrong?

{{ }} are used to get the string representation of the variable/fuction. {% %} are used to make some code working. Both can read variables/functions as they are passed with context without any additional {{/{% inside them because they process given arguments directly.

This error usually means you've forgotten a closing quote somewhere in the template you're trying to render. For example: {% url 'my_view %} (wrong) instead of {% url 'my_view' %} (correct). In this case it's the colon that's causing the problem. Normally you'd edit the template to use the correct {% url %} syntax.

How to make Django url template with variable find the correct url

In my urls.py I have:
path('experiments/charts/<str:part_tag>/', ExpViews.bokehChart, name='part_tag')
I'd like to pass a string argument "part_tag" to the function bokehChart.
and I'm trying to give the "path_tag" string variable some values as follows:
{% for part in parts %}
<ul class="list=group">
{% for datapoint in part.datapoints %}
{{datapoint}}
{% endfor %}
</ul>
{% endfor %}
I get the following error on my webpage:
Reverse for 'part_tag' not found. 'part_tag' is not a valid view function or pattern name.
I know similar questions have been asked, but I can't get it to work in my case.

Django: Named URLs / Same Template, Different Named URL

I have a webapp that lists all of my artists, albums and songs when the appropriate link is clicked. I make extensive use of generic views (object_list/detail) and named urls but I am coming across an annoyance. I have three templates that pretty much output the exact same html that look just like this:
{% extends "base.html" %}
{% block content %}
<div id="content">
<ul id="starts-with">
{% for starts_with in starts_with_list %}
<li>{{ starts_with|upper }}</li>
{% endfor %}
</ul>
<ul>
{% for song in songs_list %}
<li>{{ song.title }}</li>
{% endfor %}
</ul>
</div>
{% endblock content %}
My artist and album template look pretty much the same and I'd like to combine the three template's into one. The fact that my variables start with song can easily be changed to the default obj. It's my <ul id="starts-with"> named url I don't know how to correct. Obviously I want it to link to a specific album/artist/song using the named urls in my urls.py but I don't know how to make it context aware. Any suggestions?
urls.py:
urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views',
# (r'^$', index),
url(r'^artists/$', artist_list, name='artist_list'),
url(r'^artists/(?P<starts_with>\w)/$', artist_list, name='artist_list_x'),
url(r'^artist/(?P<artist_id>\d+)/$', artist_detail, name='artist_detail'),
url(r'^albums/$', album_list, name='album_list'),
url(r'^albums/(?P<starts_with>\w)/$', album_list, name='album_list_x'),
url(r'^album/(?P<album_id>\w)/$', album_detail, name='album_detail'),
url(r'^songs/$', song_list, name='song_list'),
url(r'^songs/(?P<starts_with>\w)/$', song_list, name='song_list_x'),
url(r'^song/(?P<song_id>\w)/$', song_detail, name='song_detail'),
)

You could define url patterns for a generic object_type instead of individually for artists, albums and songs:
urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views',
# (r'^$', index),
url(r'^(?P<object_type>\w+)/$', music_object_list, name='music_object_list'),
url(r'^(?P<object_type>\w+)/(?P<starts_with>\w)/$', music_object_list, name='music_object_list_x'),
url(r'^(?P<object_type>\w+)/(?P<object_id>\d+)/$', music_object_detail, name='music_object_detail'),
)
Then in your template, your url tag becomes
{% url music_object_list_x object_type starts_with %} *
You may find you only need one view, music_object_list. If you find you need different functions for each object type, then call the individual functions in music_object_list.
def music_object_list(request, object_type, starts_with=None):
if object_type == 'artists':
return artist_list(request, starts_with=starts_with)
elif object_type == 'albums':
return album_list(request, starts_with=starts_with)
...
If you are using django.views.generic.list_detail.object_list, then remember to add object_type to the extra_context dictionary. This will add object_type to the template context, allowing the url tag to work.
extra_context = {'object_type': 'songs', ...}
* This is the new url tag syntax for Django 1.2. For older versions you would use a comma.
{% url music_object_list_x object_type,starts_with %}
See the docs (Current, 1.1) for more information

Django url tag multiple parameters

I have two similar codes. The first one works as expected.
urlpatterns = patterns('',
(r'^(?P<n1>\d)/test/', test),
(r'', test2),
{% url testapp.views.test n1=5 %}
But adding the second parameter makes the result return empty string.
urlpatterns = patterns('',
(r'^(?P<n1>\d)/test(?P<n2>\d)/', test),
(r'', test2),)
{% url testapp.views.test n1=5, n2=2 %}
Views signature:
def test(request, n1, n2=1):

Try
{% url testapp.views.test n1=5,n2=2 %}
without the space between the arguments
Update:
As of Django 1.9 (and maybe earlier) the correct way is to omit the comma and separate arguments using spaces:
{% url testapp.views.test n1=5 n2=2 %}

Here's an actual example of me using this technique. Maybe this will help:
{% if stories %}
<h2>Stories by #{{author.username}}</h2>
<ul>
{% for story in stories %}
<li>{{story.title}}</li>
{% endfor %}
</ul>
{% else %}
<p>#{{author.username}} hasn't published any stories yet.</p>
{% endif %}

Django 1.1 - comments - 'render_comment_form' returns TemplateSyntaxError

I want to simply render a built-in comment form in a template, using Django's builtin commenting module, but this returns a TemplateSyntaxError Exception.
I need help debugging this error, please, because after googling and using the Django API reference, I'm still not getting any farther.
Info:
This is the template '_post.html'[shortened]:
<div id="post_{{ object.id }}">
<h2>
{{ object.title }}
<small>{{ object.pub_date|timesince }} ago</small>
</h2>
{{ object.body }}
{% load comments %}
{% get_comment_count for object as comment_count %}
<p>{{ comment_count }}</p>
<!-- Returns 0, because no comments available -->
{% render_comment_form for object %}
<!-- Returns TemplateSyntaxError -->
This is the Exception output, when rendering:
Caught an exception while rendering: Reverse for 'django.contrib.comments.views.comments.post_comment'
with arguments '()' and keyword arguments '{}' not found.1
{% load comments i18n %}
<form action="{% comment_form_target %}" method="post">
{% if next %}<input type="hidden" name="next" value="{{ next }}" />{% endif %}
{% for field in form %}
{% if field.is_hidden %}
{{ field }}
{% else %}
{% if field.errors %}{{ field.errors }}{% endif %}
<p
{% if field.errors %} class="error"{% endif %}
{% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}>
{{ field.label_tag }} {{ field }}
/posts/urls.py[shortened]:
queryset = {'queryset': Post.objects.all(),
'extra_context' : {"tags" : get_tags}
}
urlpatterns = patterns('django.views.generic.list_detail',
url('^$', 'object_list', queryset,
name='posts'),
url('^blog/(?P<object_id>\d+)/$', 'object_detail', queryset,
name='post'),
)
/urls.py[shortened]:
urlpatterns = patterns('',
(r'', include('posts.urls')),
(r'^comments/$', include('django.contrib.comments.urls')),
)

I had the same exact problem, render_comment_form template tag was triggering it.
The issue is certainly with your URL config, you had it set the same way i did:
(r'^comments/$', include('django.contrib.comments.urls'))
The correct way is to remove the '$' after 'comments/':
(r'^comments/', include('django.contrib.comments.urls'))
Otherwise django can't properly include all necessary urls under the path comments/...
Hope this helps.

The error message is indicated that it can't find a reverse url for:
django.contrib.comments.views.comments.post_comment
So basically something isn't configured right in your urls. Without being able to see more of how things are setup it's difficult to know exactly what.
Maybe try re-ordering the urls pattern includes in your urls.py, to force the django comments urls to the top?

I had this same problem today. I was referencing a view in urls.py that I hadn't created yet.
From http://docs.djangoproject.com/en/dev/topics/http/urls/#reverse
As part of working out which URL names
map to which patterns, the reverse()
function has to import all of your
URLconf files and examine the name of
each view. This involves importing
each view function. If there are any
errors whilst importing any of your
view functions, it will cause
reverse() to raise an error, even if
that view function is not the one you
are trying to reverse.
Make sure that any views you reference
in your URLconf files exist and can be
imported correctly. Do not include
lines that reference views you haven't
written yet, because those views will
not be importable.

This error is saying that it found the view django.contrib.comments.views.comments.post_comment
but no args () or kwargs{} were passed.
Its not passing a value for object.id into the url.
Take out the url tag and see if the id of the <div id="post_{{object.id}}"> reflects a proper object.id
