succeeded in executing the for statement with one list in jinja2,
but we have to use two lists.
i try 2 list ( feeds, time ) use in jinja2
how to jinja2 for loop from jinja2
Is there a way to use two lists in jinja2?
If you want to loop over a combined list of two lists (of same length) you have to apply zip function on them. E.g.:
def view_function():
feeds = [...]
time = [...]
feeds_and_time = zip(feeds, time)
# Looks like this: [('feed_1', 'time_1'), ('feed_2', 'time_2')]
Then pass this new feeds_and_time variable to the render function. And in the template, modify the loop:
{% for feed,tim in feeds_and_time %}

In this code block, I have grouped by headings. But I want to sort the titles in array index order. Not alphabetically.
{% set list = widget.attributes.faq_item %}
{% for title_group in list|groupby('value.main_title') %}
<h2 class="account-sss__title">{{title_group.grouper}}</h2>
{% for item in title_group.list %}
<a href="#" class="account-sss__list--link js-link">
{{item.value.question}}
</a>
<div class="account-sss__content js-account-sss__content">
{{item.value.answer}}
</div>
{% endfor %}
{% endfor %}
I solved the problem.
{% set list = widget.attributes.faq_item %}
{% set Arr_titles = [] %}
{% for event in list %}
{% if event.value.main_title not in Arr_titles %}
{% do Arr_titles.append(event.value.main_title) %}
{% endif %}
{% endfor %}
{% for index in Arr_titles %}
<h2 class="account-sss__title">{{index}}</h2>
{% for item in list %}
{% if index == item.value.main_title %}
<a href="#" class="account-sss__list--link js-link">
{{item.value.question}}
</a>
<div class="account-sss__content js-account-sss__content">
{{item.value.answer}}
</div>
{% endif %}
{% endfor %}
{% endfor %}
I am facing a wired situation, using wagtail.
My Models :
class SlideBlock(blocks.StructBlock):
image = ImageChooserBlock()
caption = blocks.CharBlock(required=False)
class Meta:
template = 'home/blocks/carousel.html'
class HomePageIndex(Page):
body = StreamField([
('head', blocks.TextBlock(classname="full title")),
('text', blocks.RichTextBlock()),
('html', blocks.RawHTMLBlock()),
('slider', blocks.ListBlock(SlideBlock()))
], blank=True)
content_panels = Page.content_panels + [
StreamFieldPanel('body'),
]
# parent_page_types = []
subpage_types = ['home.HomePageIndex',
'blog.BlogPageIndex',
'blog.BlogTagPageIndex']
My Template (MAIN) :
{% with blocks=self.body %}
{% for block in blocks %}
<section>
{% elif block.block_type == 'slider' %}
in
<!-- Gate to an nested template -->
{% include_block block %}
out
{% else %}
block-type not supported
{% endif %}
</section>
{% endfor %}
</article>
{% endwith %}
My Template (nested) :
<div>
<div>
{% for x in block.value %}
<div class="carousel-item">
{% image x.image max-1920x1080 class="d-block w-100" alt="Slide" %}
</div>
{% endfor %}
</div>
</div>
Inside my database i use some test-data for testing reasons... But for some weired reason the nested template is called, as much data is inside my database. So i am not able to iterate over the ListBlock propertly. The output of the given example produces wired repeating outputs...
What did i miss / oversee?
This is because you’re looping twice. Remove the second forloop: {% for x in block.value %}. value should be accessible without the extra loop. You can get the image in your template using value.image instead of x.image
have a table with websites and a many to one table with descriptions
trying to get a list, firstly getting the latest descriptions and then displaying them ordered by the content of the descriptions...
have the following in views.py
def category(request, category_name_slug):
"""Category Page"""
context_dict = {}
try:
category = Category.objects.get(slug=category_name_slug)
subcategory = SubCategory.objects.filter(category=category)
websites = Website.objects.filter(sub_categories=subcategory, online=True, banned=False)
sites = websites
descriptions = WebsiteDescription.objects.prefetch_related("about")
descriptions = descriptions.filter(about__in=sites)
descriptions = descriptions.order_by('about', '-updated')
descs = []
last_site = "" # The latest site selected
# Select the first (the latest) from each site group
for desc in descriptions:
if last_site != desc.about.id:
last_site = desc.about.id
desc.url = desc.about.url
desc.hs_id = desc.about.id
desc.banned = desc.about.banned
desc.referral = desc.about.referral
descs.append(desc)
context_dict['descs'] = descs
context_dict['websites'] = websites
context_dict['subcategory'] = subcategory
context_dict['category'] = category
except SubCategory.DoesNotExist:
pass
return render(request, 'category.html', context_dict)
this gives me a list with sites and their latest descriptions, so i have the following in category.html
{% if category %}
<h1>{{ category.name }}</h1>
{% for subcategory in category.subcategory_set.all %}
{{ subcategory.name }} ({{ subcategory.website_set.all|length }})
{% endfor %}
{% if descs %}
{% load endless %}
{% paginate descs %}
{% for desc in descs|dictsortreversed:"description"|dictsortreversed:"officialInfo" %}
<ul id='list' class='linksteps'>
<a href="/{{ desc.about_id }}" rel="nofollow" target="_blank">
<img src="/static/screenshots/{{ desc.about_id }}.png" />
</a>
<li><h3>{{ desc.about_id }}{% if desc.title %} - {{ desc.title }} {% endif %}</h3>
{% if desc.description %}<b>Description: </b>{{ desc.description }}
<br />{% endif %} {% if desc.subject %}<b>Keywords: </b>{{ desc.subject }}
<br />{% endif %} {% if desc.type %}<b>Type: </b>{{ desc.type }}
<br />{% endif %} {% if desc.officialInfo %} {% if desc.language %}<b>Language: </b>{{ desc.language }}
<br />{% endif %} {% if desc.contactInformation %}<b>Contact info: </b>{{ desc.contactInformation }}
<br />{% endif %}
{% else %}
{% endif %}
</li>
</ul>
</div>
{% endfor %}
{% show_pages %}
{% else %}
<strong>No websites currently in category.</strong>
{% endif %}
{% else %}
The specified subcategory {{ category_name }} does not exist!
{% endif %}
Initially i used dictsort
{% for desc in descs|dictsortreversed:"description"|dictsortreversed:"officialInfo"|dictsortreversed:"referral" %}
to give me the list in the desired order, so i was all happy ;)
Then however i decided i needed some pagination because the lists became too long.
django-endless-pagination works fine and does what its supposed too, however it splits up my list before the dictsort kicks in.
is there a way to sort before pagination happens and after i ordered_by at the initial query to have the latest descriptions selected?
much obliged
EDIT:
not getting any answers so my question might not be clear.
as far as i understand i need to sort the values in context_dict at the end in views.py replacing the dictsort as in the template
SOLVED:::
doing this did the trick for me to replace the dictsort.
descs1 = sorted(descs, key=operator.attrgetter('referral', 'officialInfo', 'description'), reverse=True)
context_dict['descs'] = descs1

I have different pages with items, each item has its own price which I would like to store in one variable and then send all of them to paypal payment form.
So question is,how can I store information about price from different pages? I tried sessions but nothing happens.

I would like to do something like:
variable p is from test.py which is a list ['a','b','c','d']
{% for i in p %}
{{variable++}}
{{variable}}
result output is:
1 2 3 4
You could use loop.index:
{% for i in p %}
{{ loop.index }}
{% endfor %}
Check the template designer documentation.
In more recent versions, due to scoping rules, the following would not work:
{% set count = 1 %}
{% for i in p %}
{{ count }}
{% set count = count + 1 %}
{% endfor %}
After 2.10, to solve the scope problem, you can do something like this:
{% set count = namespace(value=0) %}
{% for i in p %}
{{ count.value }}
{% set count.value = count.value + 1 %}
{% endfor %}
As Jeroen says there are scoping issues: if you set 'count' outside the loop, you can't modify it inside the loop.
You can defeat this behavior by using an object rather than a scalar for 'count':
{% set count = [1] %}
You can now manipulate count inside a forloop or even an %include%. Here's how I increment count (yes, it's kludgy but oh well):
{% if count.append(count.pop() + 1) %}{% endif %} {# increment count by 1 #}
Or...
{% set count = [] %}
{% for something-that-loops %}
{% set __ = count.append(1) %}
<div> Lorem ipsum meepzip dolor...
{{ count|length }}
</div>
{% endfor %}
(From comments by #eyettea and #PYB)
Here's my solution:
Put all the counters in a dictionary:
{% set counter = {
'counter1': 0,
'counter2': 0,
'etc': 0,
} %}
Define a macro to increment them easily:
{% macro increment(dct, key, inc=1)%}
{% if dct.update({key: dct[key] + inc}) %} {% endif %}
{% endmacro %}
Now, whenever you want to increment the 'counter1' counter, just do:
{{ increment(counter, 'counter1') }}
if anyone want to add a value inside loop then you can use this its working 100%
{% set ftotal= {'total': 0} %}
{%- for pe in payment_entry -%}
{% if ftotal.update({'total': ftotal.total + 5}) %}{% endif %}
{%- endfor -%}
{{ftotal.total}}
output = 5
Came searching for Django's way of doing this and found this post. Maybe someone else need the django solution who come here.
{% for item in item_list %}
{{ forloop.counter }} {# starting index 1 #}
{{ forloop.counter0 }} {# starting index 0 #}
{# do your stuff #}
{% endfor %}

I was struggle with this behavior too. I wanted to change div class in jinja based on counter. I was surprised that pythonic way did not work. Following code was reseting my counter on each iteration, so I had only red class.
{% if sloupec3: %}
{% set counter = 1 %}
{% for row in sloupec3: %}
{% if counter == 3 %}
{% set counter = 1 %}
{% endif %}
{% if counter == 1: %}
<div class="red"> some red div </div>
{% endif %}
{% if counter == 2: %}
<div class="gray"> some gray div </div>
{% endif %}
{% set counter = counter + 1 %}
{% endfor %}
{% endif %}
I used loop.index like this and it works:
{% if sloupec3: %}
{% for row in sloupec3: %}
{% if loop.index % 2 == 1: %}
<div class="red"> some red div </div>
{% endif %}
{% if loop.index % 2 == 0: %}
<div class="gray"> some gray div </div>
{% endif %}
{% endfor %}
{% endif %}
Just to shed more light into this problem.
Jinja2 variables behaves differently from that of conventional scripting languages, you can't modify the variable in a for loop.Hence to bypass this behaviour you can use a dictionary, since you can change the value of the dictionary.
**{% set margin={"margin_value":0} %}**
{% for lang in language %}
<ul>
<li style="margin-right: {{ margin.margin_value}}px">{{ lang }}</li>
</ul>
**{% if margin.update({"margin_value":margin.margin_value + 2}) %}
{% endif %}**
{% endfor %}
In the above code the value of the dictionary is being modified.
