I am customizing my admin panel a little and want to add an additional column to it, so as per the docs I have to override the change_form_results.html file but how do I do it? all I see is this code in it
<tbody>
{% for result in results %}
{% if result.form and result.form.non_field_errors %}
<tr><td colspan="{{ result|length }}">{{ result.form.non_field_errors }}</td> </tr>
{% endif %}
<tr>{% for item in result %}
{{ item }}
{% endfor %}</tr>
{% endfor %}
</tbody>
what change am i suppose to make to above code

Django 2.2
I have a list view controlled by admin.py class. No custom template, all default. I can control what fields from the table should be shown in the view with this:
fields = ('myfield1','myfield2', ...).
Each row in the list table has a checkbox in the first column, the source looks like this:
<td class="action-checkbox">
<input type="checkbox" name="_selected_action" value="123" class="action-select">
</td>
My questions are:
How to disable those checkboxes (preferably, from Django code, without introducing a custom template) ?
Can it be done for SOME of the checkboxes (let's say I have a list of pk ids for the rows I don't want to see checkboxes.)
You can delete Items with those CheckBoxes, but if you want to customize your own admin page to override it
You can use this doc https://docs.djangoproject.com/en/3.0/ref/contrib/admin/#admin-overriding-templates
This question is 2 years old now, but for the case someone still needs it, the following code works to overwrite the change-list_results.html:
{% load i18n static %}
{% if result_hidden_fields %}
<div class="hiddenfields">{# DIV for HTML validation #}
{% for item in result_hidden_fields %}{{ item }}{% endfor %}
</div>
{% endif %}
{% if results %}
<div class="results">
<table id="result_list">
<thead>
<tr>
{% for header in result_headers %}
{% if "checkbox" in header.text %}
{% else %}
<th scope="col" {{ header.class_attrib }}>
{% if header.sortable %}
{% if header.sort_priority > 0 %}
<div class="sortoptions">
<a class="sortremove" href="{{ header.url_remove }}" title="{% translate "Remove from sorting" %}"></a>
{% if num_sorted_fields > 1 %}<span class="sortpriority" title="{% blocktranslate with priority_number=header.sort_priority %}Sorting priority: {{ priority_number }}{% endblocktranslate %}">{{ header.sort_priority }}</span>{% endif %}
</div>
{% endif %}
{% endif %}
<div class="text">{% if header.sortable %}{{ header.text|capfirst }}{% else %}<span>{{ header.text|capfirst }}</span>{% endif %}</div>
<div class="clear"></div>
{% endif %}
</th>{% endfor %}
</tr>
</thead>
<tbody>
{% for result in results %}
{% if result.form and result.form.non_field_errors %}
<tr><td colspan="{{ result|length }}">{{ result.form.non_field_errors }}</td></tr>
{% endif %}
<tr>
{% for item in result %}
{% if "_selected_action" in item %}
{% else %}
{{ item }}
{% endif %}
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
</div>
{% endif %}
It stops stops the output of the for loops if theres a checkbox in there. --> It just removes the checkboxes.
I can not work-out what I am doing wrong with collapsing certain rows of my table.
Can you advice how can I correct it so I can collapse rows marked in red ?
I guess I have placed collapse tag in wrong place or have not used again ? However can I use table in table ?
my template:
{% extends "base.html" %}
{% block content %}
<h3>{% for project in projects %}{{ project.project_name }}{% endfor %}</h3>
<table class="table table-striped table table-bordered table table-hover table table-condensed">
<tr>
<td></td>
<!-- row with zone names -->
{% for z in zones %}
<td style="width:40px" align="center">{{ z.zone_name }}</td>
{% endfor %}
</tr>
<!-- rows with stage names -->
{% for trstage in trstages %}
<tr>
<td style="width:40px"><a data-toggle="collapse" href="#collapse{{ trstage }}">{{ trstage.stage_name }}</a></td>
<!-- row with stage value -->
{% for stage in trstage.stages %}
{% for zone in zones|dictsort:"zone_name" %}
{% if zone == stage.zone %}
<td style="width:40px" align="center">{{ stage.substage_sum.sum }}</td>
{% endif %}
{% endfor %}
{% endfor %}
</tr>
<div id="collapse{{ trstage }}" class="panel-collapse collapse">
<!-- rows with substages names -->
{% for trsubstage in trstage.related_trsubstages %}
<tr>
<td>{{ trsubstage.substage_name }}</td>
<!-- row with substage value -->
{% for substage in trsubstage.substages_related %}
{% for zone in zones %}
{% if zone == substage.stage.zone %}
<td style="width:40px" align="center">{{ substage.substage_value }}</td>
{% endif %}
{% endfor %}
{% endfor %}
</tr>
{% endfor %}
</div>
{% endfor %}
</table>
{% endblock %}
Below is link to my current template view:
Try adding the id of your trstage to the href and id of the divs. I did something similar in my project and it worked. I hope it works for you too. Like this,
<div id="{{ trstage.id.value }}" class="panel-collapse collapse">
and
<a data-toggle="collapse" href="#{{ trstage.id.value }}">{{ trstage.stage_name }}
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 %}
I am using a Django formset for this model:
class Book(models.Model):
book_id=models.AutoField(primary_key=True,unique=True)
book_name=models.CharField(max_length=30)
publisher_name=models.CharField(max_length=40)
author=models.ForeignKey(Author)
The formset is defined thus:
BookFormset = inlineformset_factory(Author, Book,
fields=('book_id','book_name', 'publisher_name'), extra=1,
can_delete=False)
The template is:
{{ formset.non_form_errors.as_ul }}
<table id="formset" class="form">
{% for form in formset.forms %}
{% if forloop.first %}
<thead><tr>
{% for field in form.visible_fields %}
<th>{{ field.label|capfirst }}
{% endfor %}
</tr></thead>
{% endif %}
<tr class="{% cycle row1,row2 %}">
{% for field in form.visible_fields %}
<td>
{# Include the hidden fields in the form #}
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
{% endfor %}
</tr>
{% endfor %}
</table>
The fields are displayed column-wise, but I would like them to be displayed row-wise.
The above code produces output like this:
Book name Publisher name
book_field Publisher_field
I would like the output to look like this:
Book name book_field
Publisher name Publisher_field
How can I do this?
In your template, you have two <tr> elements, each of which contains a loop over form.visible_fields, each iteration of which generates a single <th> or <td>.
Change this round so that you have a single loop over form.visible_fields, each iteration of which contains a single <tr> element containing a <th> and a <td>. Like this:
<table id="formset" class="form">
{% for form in formset.forms %}
{% for field in form.visible_fields %}
<tr class="{% cycle row1,row2 %}">
<th>{{ field.label|capfirst }}</th>
<td>
{# Include the hidden fields in the form #}
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
</tr>
{% endfor %}
{% endfor %}
</table>
The examples above seem to show a column-wise layout, which appears to be the default layout when a formset renders itself.
To make it row-wise, use something like this:
<table>
{% for form in formset.forms %}
{% if forloop.first %}
<thead>
{% for field in form.visible_fields %}
<th>{{ field.label }}</th>
{% endfor %}
</thead>
<tbody>
{% endif %}
<tr class="{% cycle row1,row2 %}">
{% for field in form.visible_fields %}
<td>
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
{% endfor %}
</tr>
{% if forloop.last %}
</tbody>
{% endif %}
{% endfor %}
</table>
I have the following dictionary passed to a render function, with sources being a list of strings and title being a string potentially equal to one of the strings in sources:
{'title':title, 'sources':sources})
In the HTML template I'd like to accomplish something among the lines of the following:
{% for source in sources %}
<tr>
<td>{{ source }}</td>
<td>
{% if title == {{ source }} %}
Just now!
{% endif %}
</td>
</tr>
{% endfor %}
However, the following block of text results in an error:
TemplateSyntaxError at /admin/start/
Could not parse the remainder: '{{' from '{{'
...with {% if title == {{ source }} %} being highlighted in red.
You shouldn't use the double-bracket {{ }} syntax within if or ifequal statements, you can simply access the variable there like you would in normal python:
{% if title == source %}
...
{% endif %}
Sorry for comment in an old post but if you want to use an else if statement this will help you
{% if title == source %}
Do This
{% elif title == value %}
Do This
{% else %}
Do This
{% endif %}
For more info see https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#if
{% for source in sources %}
<tr>
<td>{{ source }}</td>
<td>
{% ifequal title source %}
Just now!
{% endifequal %}
</td>
</tr>
{% endfor %}
or
{% for source in sources %}
<tr>
<td>{{ source }}</td>
<td>
{% if title == source %}
Just now!
{% endif %}
</td>
</tr>
{% endfor %}
See Django Doc
You try this.
I have already tried it in my django template.
It will work fine. Just remove the curly braces pair {{ and }} from {{source}}.
I have also added <table> tag and that's it.
After modification your code will look something like below.
{% for source in sources %}
<table>
<tr>
<td>{{ source }}</td>
<td>
{% if title == source %}
Just now!
{% endif %}
</td>
</tr>
</table>
{% endfor %}
My dictionary looks like below,
{'title':"Rishikesh", 'sources':["Hemkesh", "Malinikesh", "Rishikesh", "Sandeep", "Darshan", "Veeru", "Shwetabh"]}
and OUTPUT looked like below once my template got rendered.
Hemkesh
Malinikesh
Rishikesh Just now!
Sandeep
Darshan
Veeru
Shwetabh
