I will try to explain myself as best I can:
I am developing a kind of social network, in wich there are people registered and you can add as your friends. Once you have friends adds to your list of friends, when you want to list all the users that are in the social network (with Jinja2), I would like to inform somehow which of those users are your friends, for example:
{% for user in user_list %}
<tr>
<td> {{ user.username }}</td>
</tr>
{% endfor %}
The code above will show all the usernames registered on the website. And the code below the usernames of my friends:
{% for friend in friends_list %}
<tr>
<td> {{ friend.username }}</td>
</tr>
{% endfor %}
How can I do something like:
{% for user in user_list %}
<tr>
{% if user "is inside" friends_list %}
<td> {{ user.username }}</td>
<td> FRIEND</td>
{% else %}
<td> {{ user.username }}</td>
<td>NO FRIEND</td>
{% endif %}
</tr>
{% endfor %}
I went through the Jijna2 documentation and I didn't find anything usefull...
Thanks verymuch!
Why not use user in friends_list ...
{% for user in user_list %}
<tr>
{% if user in friends_list %}
<td> {{ user.username }}</td>
<td> FRIEND</td>
{% else %}
<td> {{ user.username }}</td>
<td>NO FRIEND</td>
{% endif %}
</tr>
{% endfor %}
Hope this helps!

I am trying to create a table with HTML tags but I am stuck with it.
I've tried to play with {% for i in list %}, but I couldn't find a solution.
list = {'ticker': tickers, 'price': prices}
<tbody>
<tr>
{% for i in price %}
<td>{{ i }}</td>
{% endfor %}
{% for i in ticker %}
<td>{{ i }}</td>
{% endfor %}
</tr>
<tr>
</tr>
</tbody>
I would see two columns one close to another, but I don't see any columns now.
try this
<tbody>
{% for i in list %}
<tr>
<td>{{ i.ticker }}</td>
<td>{{ i.price }}</td>
</tr>
{% endfor %}
</tbody>

hope it helps
Okay, I'll try to make it short.
I got an XML file from Musicbrainz. Then I converted it to CSV and replaced the .'s with _'s to make it work with Liquid.
I put music.csv in _data and call it with:
{% include music.html %}
_includes/music.html looks (in part) like:
<table border="1" style="width:100%">
<tr>
<td>Artist</td>
<td>Track title</td>
</tr>
<tr>
{% if member.release_medium-list_medium_track-list_track_0_recording_artist-credit_name-credit_artist_name %}
<td>{{ member.release_medium-list_medium_track-list_track_0_recording_artist-credit_name-credit_artist_name }}</td>
{% endif %}
{% if member.release_medium-list_medium_track-list_track_0_recording_title %}
<td>{{ member.release_medium-list_medium_track-list_track_0_recording_title }}</td>
{% endif %}
</tr>
<tr>
{% if member.release_medium-list_medium_track-list_track_1_recording_artist-credit_name-credit_artist_name %}
<td>{{ member.release_medium-list_medium_track-list_track_1_recording_artist-credit_name-credit_artist_name }}</td>
{% endif %}
{% if member.release_medium-list_medium_track-list_track_1_recording_title %}
<td>{{ member.release_medium-list_medium_track-list_track_1_recording_title }}</td>
{% endif %}
</tr>
<tr>
{% if member.release_medium-list_medium_track-list_track_2_recording_artist-credit_name-credit_artist_name %}
<td>{{ member.release_medium-list_medium_track-list_track_2_recording_artist-credit_name-credit_artist_name }}</td>
{% endif %}
{% if member.release_medium-list_medium_track-list_track_2_recording_title %}
<td>{{ member.release_medium-list_medium_track-list_track_2_recording_title }}</td>
{% endif %}
</tr>
Now, clearly, this is not the best way to do it. What I'm after is something that:
Looks for the relevant data
If the data is there, creates the cells and fills them out.
I'm pretty sure this can be done with Liquid, but I have no idea how. Can someone here help?
EDIT: Turns out I forgot the CSV file -- here it is, on Pastebin.
EDIT 2: This Cheat Sheet might be of help!
The format of a CSV file inherently does not support repeated sections so I think it would be a bad fit for the variable length data format you are trying to use. I feel JSON is more appropriate for this use case as it can handle the structure of the source data you are trying to work with.
As a quick example I put the XML file you supplied through this converter to create a JSON version of the output. This was saved as "_data/music.json".
This liquid code was then used to parse this:
{% for item in site.data.music %}
<h2> {{ item[1].release.title }}</h2>
{% for medium in item[1].release.medium-list %}
<h3> {{ medium[1].format }} </h3>
<table border="1" style="width:100%">
<tr>
<td>Artist</td>
<td>Track title</td>
</tr>
{% for track in medium[1].track-list.track %}
<tr>
<td>{{ track.recording.artist-credit.name-credit.artist.name }}</td>
<td>{{ track.recording.title }}</td>
</tr>
{% endfor %}
</table>
{% endfor %}
{% endfor %}
This produces HTML like this (trimmed):
<h2> The Quatermass Film Music Collection</h2>
<h3> CD </h3>
<table border="1" style="width:100%">
<tr>
<td>Artist</td>
<td>Track title</td>
</tr>
<tr>
<td>Tristram Cary</td>
<td>Quatermass and the Pit: Opening Credits</td>
</tr>
<tr>
<td>Tristram Cary</td>
<td>Quatermass and the Pit: Bones</td>
</tr>
</table>
Based on this you should be able to produce the format you ultimately want.
This is a simple way to iterate over a csv file.
<div class="table-responsive">
<table class="table">
<thead>
<tr>
{% for column in include.datafile[0] %}
<th>{{ column[0] }}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for spec in include.datafile %}
<tr>
{% for value in spec %}
<td>{{ value[1] }}</td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
</div>
I have a list of list like :
[[elem0, elem1, elem2], [elem3, elem4, elem5], [elem6, elem7, elem8], ...]
I wrote the follow template file :
{% for result in results %}
<tr>
<td>result[0]</td>
<td>result[1]</td>
<td>result[2]</td>
</tr>
{% endfor %}
But it didn't work, What i can think is use nested for. Is there another method to access the element in the list in jinja?
You still need to output the loop variables inside braces.
{% for result in results %}
<tr>
<td>{{ result[0] }}</td>
<td>{{ result[1] }}</td>
<td>{{ result[2] }}</td>
</tr>
{% endfor %}
Also, consider a nested for loop:
{% for result in results %}
<tr>
{% for elem in result %}
<td>{{elem}}</td>
{% endfor %}
</tr>
{% endfor %}
I'm creating an e-commerce website and I wanted to build a page where I could view a list of all the orders created.
If the order contains just 1 type of item, the format works correctly, but i can't think of a way to construct the table when there are multiple types of items ordered.
This is how it looks like when there are 2 items ordered (last entry):
I want the "Queso Burrito" to be right under "steak and egg burrito" for #18.
This is my code:
<table>
<tr>
<td>#</td>
<td>Name</td>
<td>Email</td>
<td>Phone</td>
<td>Order</td>
<td>Order Quantity</td>
<td>Delivered</td>
</tr>
{% for ord in orders %}
<tr>
<td>{{ord.pk}}</td>
<td>{{ord.user.first_name}}</td>
<td>{{ord.user.email}}</td>
<td>{{ord.user.get_profile.phone}}</td>
{% for food in ord.orderitem_set.all %}
<td>{{food.name}}</td>
<td>{{food.quantity}}</td>
{% endfor %}
<td>x</td>
</tr>
{% endfor %}
</table>
With multiple items, you typically see tables with order data repeated for each line item.
{% for order in orders %}
{% for orderitem in order.items %}
<td>{{order.id}}</td><td>...</td>
{% endfor %}
{% endfor %}
If you want exactly the formatting you described, you could check if the inner loop is past its first item and hide the fields you don't want repeated.
<table>
{% for ord in orders %}
{% for item in ord.orderitem_set.all %}
<tr>
{% if forloop.counter == 1 %}
<td>{{ord.pk}}</td>
<td>{{ord.user.first_name}}</td>
<td>{{ord.user.email}}</td>
<td>{{ord.user.get_profile.phone}}</td>
{% else %}
<td colspan="4"></td>
{% endif %}
<td>{{item.name}}</td>
<td>{{item.quantity}}</td>
<td>{% if forloop.counter == 1 %}x{% endif %}</td>
</tr>
{% endfor %}
{% endfor %}
</table>
I have a table made of of several records, with the rows having different number of records per row. What I'd like to have is for the rows with less records, I want to have them being equal in length to the longest row. Currently what I have comes out like below:
I've done this using this bit of code:
<table>
{% for week in month_days %}
{% for day, entries, weekday in week %}
<tr class="{% cycle 'row1' 'row2' %}">
{% if day != 0 %}
<td>{{ weekday }}</td>
<td>{{ day }}</td>
{% if entries %}
{% for entry in entries %}
<td>{{ entry.start_time|time:"h:i a" }}</td>
<td>{{ entry.end_time|time:"h:i a" }}</td>
<td>{{ entry.hours }}</td>
<td>Break</td>
{% endfor %}
{% endif %}
{% endif %}
</tr>
<!--- Insert blank row after each Sunday -->
{% if weekday == "Sunday" %}
<tr class="week-end">
<td colspan="{{ days_month.count }}"> </td>
</tr>
{% endif %}
{% endfor %}
{% endfor %}
</table>
From the above photo, as an example, I want, on the entry for Monday 16th, to have the blue space filled in with blank cells.
Try this:
{% if entries %}
{% for entry in entries %}
<td>{{ entry.start_time|time:"h:i a" }}</td>
<td>{{ entry.end_time|time:"h:i a" }}</td>
<td>{{ entry.hours }}</td>
<td>Break</td>
{% endfor %}
{% else %}
<td> </td>
<td> </td>
<td> </td>
{% endif %}
