I am learning Django and I am unable to get why some code is merely in { } brackets and while other is {% %}. What'the difference?
Example is given below:
{% extends "layout.html" %}
{% block body %}
<ul>
{% for user in users %}
<li> {{ user.username }} </li>
{% endfor %}
</ul>
{% endblock %}
The {%...%} block executes a statement, while the {{...}} block evaluates an expression and outputs the returning value of the evaluation.
Please read the documentatition, it is pretty clear and full with various sample code.
Jinja documentation
I'm making a site for which I use cmsplugin-articles 0.2.2. That means that there's a page on the site (News) which has nested child pages which are the news. In the parent page you view a list of news teasers. (This is the way the plugin works.)
Looking into the template of the article teaser that the plugin provides:
{% load article_tags i18n %}
<div class="article">
{% block teaser_head %}
<time datetime="{{ article|published_at|date:"Y-m-d" }}">{{ article|published_at|date:"d.m.Y" }}</time>
<h2>{{ article|teaser_title }}</h2>
{% endblock %}
{% block teaser_body %}
{% with article|teaser_image as image %}
{% if image %}
<img src="{{ image.url }}" />
{% endif %}
{% endwith %}
<p>
{% teaser_text article %}
{% trans "More" %}
</p>
{% endblock %}
</div>
you can see the templatetag {% teaser_text article %} that should show some kind of text in the news teaser when rendering the News page.
I've published some news with some text for each one and when I go to the News page I can see the teasers list ok, but not any text, only the title, date, paginator and the "more" link, that proceed from other templatetags different than {% teaser_text %}.
Now the question is: does anybody knows how I can show each news text into each teaser (better an extract) when rendering the News page?
URL pattern declaration from views.py
url(r'^intentions/(\d+)/$', 'intentions.views.show'),
When I am writing address directly, like intentions/1 works ok, but when I trying to display URL show for object like:
{% for i in intentions %}
{% url 'intentions.views.show' i.id as iUrl %}
<li>{{ i }}</li>
{% endfor %}
I am ending with empty href. Could someone give me any advice?
If you are using Django 1.3 or 1.4, make sure you are loading the new url tag. Add the following line to the top of your template:
{% load url from future %}
If you are using Django 1.4 or earlier, and you haven't loaded the new url tag as above, then you need to remove the single quotes from the url pattern:
{% url intentions.views.show i.id as iUrl %}
As an aside, it's recommended to name your url pattern:
url(r'^intentions/(\d+)/$', 'intentions.views.show', name='show_intention'),
Then change your template to:
{% for i in intentions %}
{% url 'show_intention' i.id as iUrl %}
<li>{{ i }}</li>
{% endfor %}
you could try
{% for i in intentions %}
<li><{{ i }}</li>
{% endfor %}
don't use {% url 'intentions.views.show' i.id as iUrl %}, it's maybe confused.
Also,you could try modifiy the url as follow
url(r'^intentions/(\d+)/$', 'intentions.views.show', name="intention_view"),
then,
{% for i in intentions %}
{% url "intention_view" i.id as iUrl %}
<li>{{ i }}</li>
{% endfor %}
If there are also ending empty href,try the first method.
'intentions.views.show'
Also give a name='' to your URL and use it in your template code.
Im trying to format my search page so that it will split my results by model_name.
The problem i've got is that my heading get repeated because its inside the for loop. Is there any way to re-write this code so that the heading is only shown once?
Thanks
{% for result in page.object_list %}
{% ifequal result.model_name 'post' %}
<h3>Videos</h3>
<p>
{{ result.object.title }}
</p>
{% else %}
<h3>Photos</h3>
<p>
{{ result.object.title }}
</p>
{% endifequal%}
{% empty %}
<p>No results found.</p>
{% endfor %}
Check ifchanged tag.
Usual algorithm in such cases is:
1) Sort results on heading field
2) Use ifchanged tag.
How do you get Django comments to redirect back to the same page where you're filling out a comment if there are errors in the comment submission form?
So basically I have a template like this:
{% block content %}
{% render_comment_form for show %}
{% get_comment_count for show as comment_count %}
<div id="comments-count">
{% if comment_count == 0 %}
No comments yet. Be the first!
{% else %}
Number Of Comments: {{ comment_count }}
{% endif %}
</div>
{% if comment_count > 0 %}
{% render_comment_list for show %}
{% endif %}
{% endblock %}
I created my own list.html and form.html and everything looks fine. In the form.html template there is some code like this:
<ul class="form-errors">
{% for field in form %}
{% for error in field.errors %}
<li>{{ field.label }}: {{ error|escape }}</li>
{% endfor %}
{% endfor %}
</ul>
So obviously, if there is an error in the comment submission form, I would like the user to see the same page as before only with some errors displayed in the comments form. Or alternatively if this is not possible, just ignore the error and instead of transitioning to the preview.html template, it would just not save the comment and again go back to the page.
Any help? Note ideally I dont want to have to create a custom comments app. This functionality should be there already. I know there's a next variable you can pass (and I am doing this), but it only works if the comment form is successful.
you have to use HttpResponseRedirect
from django.http import HttpResponseRedirect
def comment_form(request):
error = request.GET.get('error', None)
requestDict = {'error': error}
return render_to_response('comments.html', requestDict, context_instance=RequestContext(request))
def post_comment(request):
....
your code
....
if something_goes_wrong:
HttpResponseRedirect('project/comment_form/?error=ThereisProblem')
And in template you can do this:
{If error %}
<h1>{{error}}<h1>
{%else%}
render comments...
{%endif%}
Hope this will help you :)
