I have model (Event) and I want to have template with two ways to display items.
First row have to include two items, with special styling
Second one and next have to include three, with special styling
How can I do this with loop?
you can do like below
views.py
def view(request):
events = Event.objects.all()
l = []
for i in range(0,len(events), 5):
l.append((events[i:i+2], events[i+2:i+5]))
return render(request, "template.html", {"events": l})
template.html
{% for two_items, three_items in events %}
<tr class="class1">
{% for item in two_items %}
<td> {{ item }}</td>
{% endfor %}
<tr>
<tr class="class2">
{% for item in three_items %}
<td> {{ item }}</td>
{% endfor %}
<tr>
{% endfor %}
Combination of cycle and forloop tags will give you desired output:
For example:
{% for item in items %}
{% if forloop.counter < 3 %}
{% if forloop.first %}
<tr class="A">
{% endif %}
<td>{{ item }}</td>
{% endif %}
{% if forloop.counter == 3 %}
</tr>
{% endif %}
{% if forloop.counter >= 3 %}
{% cycle "<tr class='B'>" "" "" %}
<td>{{ item }}</td>
{% cycle "" "" "</tr>" %}
{% endif %}
{% endfor %}

I need to create a table one row and one row
so I wrote following code in template file ;
{% for dict_item in sonuc %}
{% if dict_item.status ==0 %}
{% if count == 1 %}
<tr>
{% set count = 0 %}
{% elif count == 0 %}
<tr class="alt">
{% set count = 1 %}
{% endif %}
<td>{{ dict_item.zaman }}</td><td>{{ dict_item.saat }}</td><td>{{ dict_item.kad }}</td><td>{{ dict_item.mak }}</td><td>{{ dict_item.uyg }}</td> </tr>
{% elif dict_item.status ==1 %}
{% if count == 1 %}
<tr>
{% set count = 0 %}
{% elif count == 0 %}
<tr class="alt">
{% set count = 1 %}
{% endif %}
<td><b>{{ dict_item.zaman }}</b></td><td><b>{{ dict_item.saat }}</b></td><td><b>{{ dict_item.kad }}</b></td><td><b>{{ dict_item.mak }}</b></td><td><font color="red"><b>{{ dict_item.uyg }}</b></font></td> </tr>
{% endif %}
{% endfor %}
but not change count value so all rows created with
<tr class="alt"> tag
as I think I 'm choose the wrong method for solution
I don't understand why I can't change the value of the" content " variable in if condition.
The Jinja2 cycle method is what you're looking for. There's an example in the docs. Note that one of the values in the cycle arguments can be an empty string.
In my models.py Task can have multiple Employer so I use ManyToManyField
In my views.py I got a date generator - it return range of 2 weeks from current day.
So here is my template
<table>
<thead>
<tr>
<th>{% trans 'employer_id' %}</th>
{% for i in date_range %}
<th>{{ i }}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for employer in employers %}
<tr>
<td>{{ employer.employer_id }}</td>
{% for t in employer.task_set.all %}
<td>{{ t }}</td>
{% empty %}
<td>0</td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
What I need is when I create a Task and assign it to employers, it should show me in the html table a start_date of Task of each employers for specific days.
So far I got this with codes above:
^date of tasks of these employers are not matching with days in the table header.
Instead of
{% for t in employer.task_set.all %}
<td>{{ t }}</td>
{% empty %}
<td>0</td>
{% endfor %}
you need to iterate over the dates again, since you're not creating <td>'s for each date.
{% for i in date_range %}
{% for t in employer.task_set.all %}
{% if t.start_date == i %}
<td>{{ t }}</td>
{% else %}
<td>-</td>
{% endif %}
{% empty %}
<td>0</td>
{% endfor %}
{% endfor %}
I have table:
{% for item in items %}
<tr>
<td>{{ forloop.counter }}</td>
<td>{{ item.field }}</td>
</tr>
{% for child in item.childs.all %}
<tr>
<td>{{ forloop.counter }}</td>
<td>{{ child.field }}</td>
</tr>
{% endfor %}
{% endfor %}
But the second forloop.counter counts inside the second loop from 1. I want to get only one counter for all rows. How to do it?
You could write a custom template tag to calculate the counter (assuming that each row has an equal number of columns):
#register.simple_tag
def abs_counter(row, col, col_total)
return return ((row - 1) * col_total) + col
and
{% for item in items %}
...
{% for child in items.children.all %}
{% abs_counter forloop.parentloop.counter forloop.counter items.children.all|length %}
{% endfor %}
{% endfor %}
i made a nested list and from that id like to make a table in my template
list looks something like
ground_skills_available = [[category1, [skill1, skill2, skill3]], [category1, [skill1, skill2]]]
Now i want to list it that you got category with below the items, next category and other items. Problem is, i have no clue about hot to show only category, instead of category +all items, since you cant seem to use the index of a list?
Can someone please help me out?
<table>
{% for categories in ground_skills_available %}
{% for category in categories %}
<tr>
<td>{{ category }}</td>
</tr>
{% for skill in category %}
<tr>
<td>{{ skill.name }}</td>
</tr>
{% endfor %}
{% endfor %}
{% endfor %}
Change your outer loop to
{% for category, skills in ground_skills_available %}
This technique is described in the Django for loop docs.
On the first iteration of the loop, this will take the list [category1, [skill1, skill2, skill3], and assign
category = category1
skills = [skill1, skill2, skill3]
You can then display {{ category }}, and loop through skills.
Putting that together, you have:
<table>
{% for category, skills in ground_skills_available %}
<tr>
<td>{{ category }}</td>
</tr>
{% for skill in skills %}
<tr>
<td>{{ skill.name }}</td>
</tr>
{% endfor %}
{% endfor %}
</table>
{% if forloop.index == 1 %} ... some code ... {% endif %}
or
{% if forloop.index0 == 0 %} ... some code ... {% endif %}
Expectation:
{% for categories in ground_skills_available %}
{% for category in categories %}
{% if forloop.first %}
<tr>
<td>{{ category }}</td>
</tr>
{% else %}
{% for skill in category %}
<tr>
<td>{{ skill.name }}</td>
</tr>
{% endfor %}
{% endif %}
{% endfor %}
{% endfor %}
I would like to write a loop like this, so that I can spread the form fields out in a table. :
{% load widget_tweaks %}
{% load mathfilters %}
{% load get_range %}
{% for k in form|length|div:5|floatformat|add:1|get_range %}
<tr>
{% for field in form %}
{% if forloop.counter >= k|mul:5 and forloop.counter <= k|mul:5|add:4 %}
<th>{{ field.label_tag }}{{ field.errors }}</th>
{% endif %}
{% endfor %}
</tr>
<tr>
{% for field in form %}
{% if forloop.counter >= k|mul:5 and forloop.counter <= k|mul:5|add:4 %}
<td>{{ field|add_class:"span4" }}</td>
{% endif %}
{% endfor %}
</tr>
{% endfor %}
This doesn't work, but because the code above fails on form|length. In order for this to work, I need to get, in a template, the number of fields in a form. Does anyone know how to do this? I've searched all over but can't find anything. The following do NOT work:
form.len
form.length
form|length
Thanks!
I'm really not sure what you are looking for, but it sounds like this:
{% for field in form %}
<tr>
{% if forloop.counter0|divisibleby:5 %}
<th class="span4">{{ field.label_tag }}{{ field.errors }}</th>
{% else %}
<th>{{ field.label_tag }}{{ field.errors }}</th>
{% endif %}
</tr>
{% endfor%}
{% for field in form %}
<tr>
{% if forloop.counter0|divisibleby:5 %}
<td>{{ field|add_class:"span4" }}</td>
{% else %}
<td>{{ field }}</td>
</tr>
{% endfor %}
I dont like this code, but it was my first idea.
{% for field in form %}
{% if forloop.last %}
{{ forloop.counter }}
{% endif %}
{% enfor %}
form.fields I believe.
{% for field_name in form.fields %}
thanks for your suggestions - they helped! Here is what finally worked for me:
{% for field in form %}
{% if forloop.counter0|divisibleby:5 %}
<tr>
{% for field in form %}
{% if forloop.counter0 >= forloop.parentloop.counter0 and forloop.counter0 <= forloop.parentloop.counter0|add:4 %}
<th>{{ field.label_tag }}{{ field.errors }} </th>
{% endif %}
{% endfor %}
</tr>
<tr>
{% for field in form %}
{% if forloop.counter0 >= forloop.parentloop.counter0 and forloop.counter0 <= forloop.parentloop.counter0|add:4 %}
<td>{{ field }}</td>
{% endif %}
{% endfor %}
</tr>
{% endif %}
{% endfor %}
