After reading all the docs, I still don't know how to truncatechars of a wagtail streamfield blocks.
{% for block in post.body %}
{% if block.block_type == 'richtext' %}
{{ block.value|truncatechars:100 }}
{% endif %}
{% endfor %}
works with weird results depending on quantity of truncatechars - if it's definitely above the number of characters of all the streamfields, it displays everything (all) as expected; Now i'm putting 40 and it displays:
First rich…
third ric…
fifth …
(my text streamfields are "first richtext", "third richtext" and "fifth richtext" ; second and third blocks are pics successfully filtered out )
I think it could be fixed by adding all of the blocks into one for output, but I don't know how to do it. Do I iterate ? There's no "+" tag :/
{{ post.body|first|truncatechars:200 }}
Is a working temporary fix, it isn't perfect because now I need to force admins to make their first streafield block a text and make it of enough length.

Maybe I'm doing it wrong (tried several ways to achieve my goal) or overlooking something here.
What I'd like to achieve is this:
When I use the Live-search function, I get categories containing the search keyword (like: Paint -> Paint buckets, Paint brushes, Paint colors etc.) which works like a charm. The one thing I need is to style the searched keyword in the presented categories like:
Paint bucket,
Paint brushes,
Color paint
This is the code I have at the moment:
{% if (products.length + categories.length + pages.length) == 0 %}
<div id="Pi56dYpB" class="undefined"> No results for:
<b>{{ query }}</b>...
</div>
{% endif %}
{% if categories.length > 0 %}
<div class="categories">
{% for category in categories %}
{% if loop.index < 7 %}
<a class="p-0" href="{{ category.url }}" style="all:inherit;">
<h3 id="bvwiyjEN" class="undefined">{{ category.name|replace({{ query }}: "<strong>"{{ query }}"<strong>"})|raw }}</h3>
</a>
{% endif %}
{% endfor %}
{% endif %}
Unfortunately this isn't working. I did check if the {{ query }} value is accessible with this simple line of code:
<h3 id="bvwiyjEN" class="undefined">{{ category.name }} - {{ query }}</h3>
No problems found here.
Did I use the wrong syntax in my code maybe? Any help would be appreciated!
replace({{ query }}) is the wrong syntax - replace(query) should work, as you don't want to echo the variable query here
As Nico Haase pointed out already, {{ ... }} is used to output variables, this translate to something like <?php echo $foo; ?> and can't/shouldn't be used inside statements
Furthermore, the filter replace expects an array of keys to replace with the values.
You would need to change your code to the following:
{% for category in categories %}
{{ category|replace({ (query): '<strong>'~query~'</strong>',})|raw }}
{% endfor %}
demo
Some notes:
The filter replace uses the PHP function strtr in the background. This mean the output will be case-sensitive. If you don't want this, I'd advice you to follow through here
Wrapping the key with parantheses is mandatory. This will force twig to evaluate/interpolate the value of the key - demo
i want in same line print two value look like "1. Question ...".
but first {{ }} after set new line. look like this,
"1."
"Question ..."
{% for q in question %}
<p> {{ forloop.counter }}. {{ q.question|safe }}</p>
{% endfor %}
How can i print two value in same line in template ?
I want this:
1.Question
2.Question
...
Based on your comment, you say that q.question is the content of a CKEditor. Often times, these output at least wrap the content inside a <p> tag. In this case, the result output generated by Django would a nested <p> tag inside the <p> from your template:
<p>1. <p>Question</p></p>
This is invalid HTML, but the browser tries to render it as best as it can. I think you can either include the number inside the CKEditor and exclude it from your template or change your field to store a simple CharField, and keep your HTML unchanged.
This depends on the flexibility you want in your application.
I am experimenting with using Grav to create my next website. One of the things I would be able to do is to build a unordered list using data provided in Grav frontmatter from the Grav page that uses the template. Here is how I am trying to do this
---
sectionone:
listitems: "['Benefit 1','Benefit 2','Benefit 3']"
---
and then in the template somehow do the following
{% block featurelist %}
<ul>
{% set items = {{page.header.sectionone.consumers.benefits|json_decode}} %}
{% for item in {{}} %}
<li>{{item}}</li>
{% endfor %}
</ul>
{% endblock %}
However, Twig does not like this and reports back an error along the lines of
Twig_Error_Syntax
A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses (unexpected token "punctuation" of value "{".
with the offending line being my {% set items = ... } statement. I am clearly doing something wrong here but I am a Twig newbie so I fail to see what that might be.
{% block featurelist %}
<ul>
{% set items = page.header.sectionone.consumers.benefits|json_decode %}
{% for item in items %}
<li>{{item}}</li>
{% endfor %}
</ul>
{% endblock %}
I figured this out eventually. Grav documentation is by and large very good. However, the documentation on page headers/frontmatter appears to be somewhat incomplete. There is no full description of the entire syntax that is understood by the frontmatter processor. In order to define an array in front matter all you need to do is the following
---
sectionone:
benefits:
- 'Benefit 1'
- 'Benefit 2'
- ...
---
In essence the standard markdown syntax for an unordered list. Grav's twig processor appears to convert this to a PHP array - no parsing required!
I'm probably missing something very obvious but can't see anything in the documentation. I have a carousel with a and each will hold an image. However I've added 6 but I want to add an if statement so if an Image has not been added you don't see a blank space, where there is no content inside the .
Here is what i've tried so far:
{% if "Carousel 1" %}
<li>
{% placeholder "Carousel 1" %}
</li>
{% endif %}
Attempt 2:
{% placeholder "Carousel 1" as cara1 %}
{% if cara1 %}
<li>
{{ cara1 }}
</li>
{% endif %}
Not sure if there is something differnt i need to be doing for the django-cms template tags?
Any help would be much appreciated. Docs here - http://docs.django-cms.org/en/latest/advanced/templatetags.html#placeholder
Not to be rude, but your approach is way, way off :)
Placeholders hold Content Plugins. Content Plugins are responsible for how they render their contents.
My advice would be to create or find a carousel content type plugin. This plugin will hold multiple images or "CarouselImage" model instances that you can iterate over, and also specify a template with which to render itself.
In this template resides the conditional statement you're wanting to check for. Placeholders are just that - places held for content plugins.
Overlap in terminology makes search for answers difficult for this one.
I'm looking for advice on the best way to implement a multiple-column display of my QuerySet that fills each column top to bottom over X columns. Meaning that the number of items in each column equals the QuerySet count divided by X (number of columns).
Using Offset doesn't work for this because I would like my data to grow into 4 columns without updating the offset manually. CSS floats work visually, but leave the data out of order.
Something like that should work for you, pass the number of columns as columns to the template:
{% for item in items %}
{% if forloop.first %}<div style="float:left;">{% endif %}
{{ item }}
{% if forloop.counter|divisibleby:columns %}
</div><div style="float:left">
{% endif %}
{% if forloop.last %}</div>{% endif %}
{% endfor %}
<div style="clear:both;"></div>
It seems like lazerscience's answer is on the right track - but I think the OP wants the data to alphabetically sort the data down the column and then start back at the top of the next column. Using divisibleby: works to break the line after 'X' items, but I think it'll take a more complex template to do what the OP wants.
Not sure if it's possible, but in the view could you: Get item count, divide by 'columns' and used that # in Divisibleby to break into the next DIV column (the visual flow will be CSS)
As Lazers's example is now you're constructing Rows and then breaking it into columns, leaving the sort order across and then down.
Sorry if I missed something.
-K
You'd better go and use a jQuery plugin to make some columns from a list.
Columnizer works very well for me
Here are some django template filter that split a list into multiple sub-lists:
list partition template filters at djangosnippets.org
You could use these in a django template to split a long list into multiple columns as follows:
{% load list_tags %}
<h2>Some List</h2>
{% for sub_list in full_list|rows:"3" %}
<ul>
{% for item in sub_list %}
<li>
{{item.name}}
</li>
{% endfor %}
</ul>
{% endfor %}
I included the template filters in my project in a file called list_tags.py. Adjust the {% load %} tag as necessary.
