I am trying to generate a url to an uploaded document (PDF, DOC...etc) on my search results page. Search is returning the items but there seems to be no url field. There is a file field which seems to have the file name, but I am unable to get a link back to this file. I am using the stock document model. Is there some sort of special tag that needs to be used like with the images?? At my wits end.
Search view
if search_query:
results = []
page_results = Page.objects.live().search(search_query)
if page_results:
results.append({'page': page_results})
doc_results = Document.objects.all().search(search_query)
if doc_results:
results.append({'docs': doc_results})
img_results = Image.objects.all().search(search_query)
if img_results:
results.append({'image': img_results})
search_results = list(chain(page_results, doc_results, img_results))
query = Query.get(search_query)
# Record hit
query.add_hit()
and the template page.
{% for result in search_results %}
{% for k, v in result.items %}
{% if k == 'page' %}
{% for item in v %}
<p>
<h4>{{ item }}</h4>
Type: Article<br>
Author: {{ item.specific.owner.get_full_name }}<br>
Publish Date: {{ item.specific.last_published_at}}
</p>
{% endfor %}
{% elif k == 'docs' %}
{% for item in v %}
<p>
<h4>{{ item.title }}</h4>
Type: Document<br>
Publish Date: {{ item.created_at }}
</p>
{% endfor %}
{% elif k == 'image' %}
{% for item in v %}
<p>
{% image item original as item_img %}
<h4>{{ item.title }}</h4>
Type: Image<br>
Publish Date: {{ item.created_at }}
</p>
{% endfor %}
{% endif%}

I need to do one page with topic and all entries about this topic. And for each entries I need all comments shown up below each entry. Comments should be for exact entry. Cant find it solution and decided ask. Thank you.
models.py
--snip--
class Comment(models.Model):
date_added = models.DateTimeField(auto_now_add=True)
text = models.TextField()
owner = models.ForeignKey(User, on_delete=models.CASCADE)
entry = models.ForeignKey(Entry, on_delete=models.CASCADE)
def __str__(self):
return f"{self.text[:50]}..."
views.py
--snip--
def topic(request, topic_id):
topic = Topic.objects.get(id=topic_id)
entries = topic.entry_set.all()
comments = []
for entry in entries:
c = entry.comment_set.all()
comments.append(c)
context = {'topic': topic, 'entries': entries,
'comments': comments}
return render(request, 'learning_logs/topic.html'
,context)
topic.html
{% extends 'learning_logs/base.html' %}
{% block content %}
<p>{{ topic.title }}</p>
<p>{{ topic.description }}</p><br>
<p>Entries:</p><br>
<ul>
{% for entry in entries %}
<li>{{ entry.text }}</li>
<ul>
<p>Comments:</p>
{% for comment in comments %}
<li>{{ comment.text }}</li>
{% endfor %}<br>
</ul>
{% empty %}
<li>Not entries</li>
{% endfor %}
</ul>
{% endblock content %}
You can do this with just topic. No need to get entries and comments:
{% extends 'learning_logs/base.html' %}
{% block content %}
<p>{{ topic.title }}</p>
<p>{{ topic.description }}</p><br>
<p>Entries:</p><br>
<ul>
{% for entry in topic.entry_set.all %}
<li>{{ entry.text }}</li>
<ul>
<p>Comments:</p>
{% for comment in entry.comment_set.all %}
<li>{{ comment.text }}</li>
{% endfor %}<br>
</ul>
{% empty %}
<li>Not entries</li>
{% endfor %}
</ul>
{% endblock content %}
You will also want to optimise the query using prefetch_related so you don't hit the db per entry per comment:
topic = Topic.objects.prefetch_related('entry_set__comment_set').get(id=topic_id))
context = {'topic': topic}
return render(request, 'learning_logs/topic.html', context)
I wanna array my collection in 3 cols, for 3 different statuses. And if there isn't any gig/item with that status, it has to say ' No projects'
I have tried this:
<div class="col-sm">
<h2>Up next</h2>
{% assign next = site.gigs | gig.status == 'Next' | sort: gig.date %}
{% if next.gigs.size == 0 %}
No projects
{% else %}
{% for gig in next %}
{{ gig.title }}
{% endfor %}
{% endif %}
</div>
<div class="col-sm">
<h2>Working on</h2>
{% assign on = site.gigs | gig.status == 'On' | sort: gig.date %}
{% if on.gigs.size == 0 %}
No projects
{% else %}
{% for gig in on %}
{{ gig.title }}
{% endfor %}
{% endif %}
</div>
<div class="col-sm">
<h2>Done</h2>
{% assign done = site.gigs | gig.status == 'Done' | sort: gig.date %}
{% if done.gigs.size == 0 %}
No projects
{% else %}
{% for gig in done %}
{{ gig.title }}
{% endfor %}
{% endif %}
</div>
But it just arrays all of the gigs/items :(
Maybe it can be done in a way more simple way.
I don't know if you could make one compact liquid code and array 3 columns by counting the number of different statuses.
Help!
Ordering
Our statuses are "Next", "On" and "Done". They must be ordered in such order.
As this is not an alphabetical sort order, we need to define this order by ourself.
In _config.yml :
status-order:
-
name: "Next" ### status as it is set on gigs (!!! Case-Sensitive !!!)
display: "Up Next" ### status column header to display
-
name: "On"
display: "Working On"
-
name: "Done"
display: "Done"
We can now loop over site.status-order and get our gigs in desired status order.
{% for status in site.status-order %}
{{ status.name }} - {{ status.display }}
{% endfor %}
Presenting
As your current code is a little repetitive, we can factor it like this :
{% for status in site.status-order %}
{% assign items = site.gigs | where: 'status', status.name | sort: date %}
<div class="col-sm">
<h2>{{ status.display }} ({{ items.size }})</h2>
{% if items.size > 0 %}
<ul>
{% for item in items %}
<li>{{ item.title }}</li>
{% endfor %}
</ul>
{% else %}
No project
{% endif %}
</div>
{% endfor %}
Note
You must be sure to set status with the right case (eg : "Next" an not "next").
And the right type. If you set status: On it is understood as the true boolean value, not the string "on". In this case the correct status expression is status: "On". It must be quoted or double quoted to be understood as "On" string.
Any item with incorrectly cased or typed status expression will not appear in our listing.
What I'm trying to do:
I'm trying to create a list for the posts each author has written. This is a problem since each post should be able to specify multiple authors.
Let's say we have 3 posts in total and 3 authors in total.
Edit 1: as suggested in the answers this is best done by listing the authors in a front matter list instead of a CSV string. So,
Like this
Post:
---
title: post
authors:
- foo
- bar
---
instead of like this:
Post:
---
title: post
authors: [foo, bar]
---
Problem setup:
(edited, according to Edit 1)
Post 1:
---
title: post1
authors:
- foo
- bar
---
Post 2:
---
title: post2
authors:
- foo
- bar
---
Post 3:
---
title: post3
authors:
- john doe
- bar
---
Out:
bar (3)
john doe (1)
foo (2)
A click on the author should then result in all posts getting displayed.
Alternatively an array can be displayed like this, but it's not helping the case, just an equivalent style.
What I tried
I did the same with categories and tags and this algorithm worked like a charm. However, replacing site.categories with site.authors is somehow not supported.
returns:
Liquid Exception: 0 is not a symbol nor a string in authors.html
I suppose this is due to the nature of categories and tags being arrays by default.
I think it would help to be able to set the front matter tag authors as an array somehow. I suppose this is done in _config.yml, but I busted by head in with it.
As of now I got as far as coming up with a way to target individual authors in an array, but I'm far from being able to list them individually and counting them up. I suppose I'm limited due to the nature of authors not being an array by default, otherwise implementations like this one would work with custom front matter variables like authors, but they don't.
What I meant (when I said "As of now"):
{% for post in site.posts %}
<li>{{ post.authors }} ({{ post.authors[0] }})</li>
{% endfor %}
Out:
foobar (foo)
foobar (foo)
john doebar (john doe)
Afterall, I think I'm missing something here. I'm probably not the first one who tried this but the only documentation I found was from people who attempted what I'm trying but didn't really get there.
This user for example created a way to count users, but when used with site.authors
it returns the array size == 0-if clause:
No author
It seems like a simple thing, but for some reason isn't. At least for me.
Edit 2:
based on Kieths answer I came closer to getting there, but I have issues with creating an emphty array. According to this issue in Jekyll this seems to be a problem in general. However a workaround seems to be to assign a variable and split it with an emphty tag.
Currently I struggle with adding authors to the array so I can assess it's size.
{% assign authors = site.posts | map: 'authors' | uniq %}
{% assign authorCount = '' | split: '' %}
<div class="softwaretitle">
{% for author in authors %}
<a>{{ author }}</a>
{% for post in site.posts %}
{% for post_author in post.authors %}
{% if post_author == author %}
{% assign authorCount = authorCount | push author %}
<a>({{ page.authorCount | size }})</a>
{% endif %}
{% endfor %Edit 2:}
{% endfor %}
{% endfor %}
</div>
Out:
Error: Liquid error (.../_includes/authors.html line 14): wrong number of arguments (given 1, expected 2) included
Error: Run jekyll build --trace for more information.
Line 14:
{% assign authorCount = authorCount | push author %}
Edit 3:
At last, the final result (without link to the post list, but thats details)
<!-- Get a list of unique authors -->
{% assign authors = site.posts | map: 'authors' | uniq | sort%}
{% assign author_post_count = 0 %}
{% for author in authors %}
{% assign author_post_count = 0 %}
<div class="">
<li><a>{{ author }}
{% for post in site.posts %}
{% for post_author in post.authors %}
{% if post_author == author %}
{% assign author_post_count = author_post_count | | plus: 1 %}
{% endif %}
{% endfor %}
{% endfor %}
<span>  ({{ author_post_count }})</span></a></li>
</div>
{% endfor %}
Out:
bar (3)
john doe (1)
foo (2)
Updated answer:
To get a list of authors (without duplicates) and including the total number of posts the author has contributed to, together with a list of posts' titles and a link to the posts.
{% assign authors = site.posts | map: 'authors' | uniq %}
{% for author in authors %}
{% assign author_post_count = 0 %}
{% for post in site.posts %}
{% if post.authors %}
{% for post_author in post.authors %}
{% if post_author == author %}
{% assign author_post_count = author_post_count | plus: 1 %}
{% endif %}
{% endfor %}
{% endif %}
{% endfor %}
<h2>{{ author }} - {{ author_post_count }}</h2>
{% for post in site.posts %}
{% if post.authors %}
{% for post_author in post.authors %}
{% if post_author == author %}
{% assign author_url_query = author | replace: ' ', '-' %}
<a href="{{ post.url }}" title="A posts {{ author }}">
{{ post.title }}
</a>
{% endif %}
{% endfor %}
{% endif %}
{% endfor %}
{% endfor %}
If instead, you want to have a page per author that includes a list of posts written by them (automatically generated), you will need to extend Jekyll through a custom plugin. This is very possible if you have experience with the Ruby programming language. This is a very close example: https://github.com/avillafiorita/jekyll-datapage_gen and you can simply remove the _config data requirements and hardcode the directory names and permalinks :)
Problem :
on a post : print author(s) + number of posts written and link to the authors page
on an author's page : print author's datas + list written posts
Solution
We already have posts that are described like this :
---
title: post2
authors: [foo, bar]
# or with the alternate YAML array syntax
authors:
- foo
- bar
---
For authors, we can user a specific collection that will automatically generate author's page.
In _config.yml :
collections:
authors:
output: true
defaults:
- scope:
type: authors
values:
layout: authors
An author's page can be described like this :
_authors/foo.md
---
uid : foo
firstname: John
lastname: Foo
---
Some bio here ...
Posts List (index or any page):
{% assign posts = site.posts %}
{% comment %}
or {% assign posts = paginator.posts %} if you use pagination
{% endcomment %}
<ul>
{% for post in posts %}
<li>
{{ p.title }}
<br>{% include authors.html post=post %}
</li>
{% endfor %}
</ul>
We will also use our authors include in _layouts/post.html
...
<h1 class="post-title" itemprop="name headline">{{ page.title | escape }}</h1>
<p>{% include authors.html post=page %}</p>
...
Now the magic : _includes/authors.html
{% assign post = include.post %}
{% comment %}## if we have a least one author in post authors array {% endcomment %}
{% if post.authors and post.authors != empty %}
{% comment %} ## We will build a string for each author,
store it in authorsArray
then reassemble it at the end {% endcomment %}
{% assign authorsArray = "" | split: "" %}
{% for author in post.authors %}
{% comment %}## Count posts for current author {% endcomment %}
{% assign authorsPostsCount = site.posts | where_exp: "post", "post.authors contains author" | size %}
{% comment %}## Get authors data based on uid matching in the collection {% endcomment %}
{% assign authorsDatas = site.authors | where: "uid", author | first %}
{% if authorsDatas %}
{% capture authorString %}
{{ authorsDatas.firstname }} {{ authorsDatas.lastname }} ({{ authorsPostsCount }})
{% endcapture %}
{% else %}
{% comment %}## No entry for this author in the collection
## or author spelling is wrong {% endcomment %}
{% capture authorString %}
{{ author | capitalize }} ({{ authorsPostsCount }})
{% endcapture %}
{% endif %}
{% comment %}## Push result in authorsArray {% endcomment %}
{% assign authorsArray = authorsArray | push: authorString %}
{% endfor %}
{% comment %}## Create a sentence with array elements {% endcomment %}
by {{ authorsArray | array_to_sentence_string }}
{% endif %}
_layouts/author.html
---
layout: default
---
<h1>{{ page.firstname }} - {{ page. lastname }}</h1>
{% assign authorsPosts = site.posts | where_exp: "post", "post.authors contains page.uid" %}
<ul>
{% for p in authorsPosts %}
<li>{{ p.title }}</li>
{% endfor %}
</ul>
I'm having trouble to check if a value is present in an array with Twig.
I want to hide a shipping method in a checkout if there's a certain product in the cart.
I can only use Twig code so I have to find a logic in that.
So let's say when product ID 1234 is in cart then I want to hide #certain_div
So what I have is this ->
{% if checkout %}
{% set array = theme.sku_shipping_rule | split(',') %}
// theme.sku_shipping_rule = a text string like 1234, 4321, 5478
{% if checkout.products %}
{% for product in checkout.products %}
{% if product.sku in array %}
<style>
#certain_div {
display: none;
}
</style>
{% endif %}
{% endfor %}
{% endif %}
{% endif %}
The problem I'm facing is that it seems my code always returns true. So even if the product.sku doens't match a value in the array it still hides #certain_div. I've tested that with placing {{ product.sku }} just before <style>.
What do I wrong?
Any help greatly appreciated!
UPDATE:
I've updated the question/code to show what's happening
{% if checkout %}
{% set skuToCheck = theme.sku_shipping_rule | split(',') %}
{% set skuInCart = [] %}
{% if checkout.quote.products %}
{% for product in checkout.quote.products %}
{% set skuInCart = skuInCart | merge([product.sku]) %}
{% endfor %}
{% endif %}
{% for myVar in skuInCart %}
{{ myVar }}<br/>
{% endfor %}
// this prints
PSYGA1 // where this sku should NOT match
FP32MA4
{% for myVar in skuToCheck %}
{{ myVar }}<br/>
// this prints
FP32LY4
FP32STR4
FP32MA4
{% if myVar in skuInCart %} // also tried with | keys filter
{{ myVar }} is found
{% endif %}
{% endfor %}
{% endif %}
So what I did is placing the sku's from the products which are in the cart in an array skuInCart. Next I want to check if myVar is present in the skuInCart array. If so print myVar is found.
What happens is that you should expect that it prints only the matching results. However it actually prints all values present skuInCart (using keys filter) or completely blank without using keys filter.
What you are doing in theory should work, have a look a this fiddle example to show you a working demonstration:
https://twigfiddle.com/yvpbac
Basically:
<div id="certain_div">
This should not show up
</div>
{% set searchForSku = "890" %}
{% set productSkuArrayString = "1234,4567,890" %}
{% set productSkuArray = productSkuArrayString|split(',') %}
{% if searchForSku in productSkuArray %}
<style>
#certain_div {
display: none;
}
</style>
{% endif %}
<!-- New Trial -->
<div id="certain_div">
This should show up
</div>
{% set searchForSku = "891" %}
{% set productSkuArrayString = "1234,4567,890" %}
{% set productSkuArray = productSkuArrayString|split(',') %}
{% if searchForSku in productSkuArray %}
<style>
#certain_div {
display: none;
}
</style>
{% endif %}
Will result in:
<div id="certain_div">
This should not show up
</div>
<style>
#certain_div {
display: none;
}
</style>
<!-- New Trial -->
<div id="certain_div">
This should show up
</div>
You can use iterable to check if a variable is an array or a traversable object:
{% if items is iterable %}
{# stuff #}
{% endif %}
I have the following code
<div>
{% for note in site.regnotes %}
{% if note.regulationno == page.regulationno %}
<p>
{{ note.regulationno }} - {{ note.url }}
</p>
{% endif %}
{% endfor %}
</div>
This code loops over the regnotes collection in a jekyll site, checks if the current note regulationno is the same as the page regulationno and if so displays the regulationno and url - that is the url of the current page. How do I change this code to include the url of the previous page, the current page and the next page. I'm looking for three urls - previous, current and next? - The "page.previous.url" variable within jekyll does not appear to work in collections.
This is what it might look like in other code
for i=1 to number of items in the regnotes collection
if current note == page note
print page[i].url //current page url
print page[i-1].url //previous page url
print page[i+1].url //next page url
end if
end for
I suppose what I'm trying todo is reference the items in the collection by their array index. just can't seem to get the syntax correct.
Since you are a programmer, you just need to know that you need to use forloop.index0 to know where you are in the for loop (https://docs.shopify.com/themes/liquid-documentation/objects/for-loops#index0).
The code will be something like:
<div>
{% for note in site.regnotes %}
{% assign current_index = forloop.index0 }}
{% assign next_index = current_index | plus: 1 %}
{% assign prev_index = current_index | minus: 1 %}
{% if note.regulationno == page.regulationno %}
<p>
{{ note.regulationno }} - {{ note.url }}
</p>
{% if site.regnotes[prev_index] %}prev{% endif %}
{% if site.regnotes[next_index] %}next{% endif %}
{% endif %}
{% endfor %}
</div>
