I have a list of categories from DB as following and it works fine + sorted by ID.
{% for category in menu_categories|sort(attribute="id"): %}
<div>
{{ category.name }}
</div>
{% endfor %}
I just need one exception if category='Pizza' exist to list it first.
Unless I misunderstood you, this should do it:
{% for category in menu_categories|sort(attribute="id"): %}
{% if category.name == 'Pizza': %}
<div> {{ category.name }} </div>
{% endif %}
{% endfor %}
{% for category in menu_categories|sort(attribute="id"): %}
{% if category.name != 'Pizza': %}
<div> {{ category.name }} </div>
{% endif %}
{% endfor %}

Im trying to raise error for empty fields or fields which are not validating in form
so Im doing this method below but I know this is not the best way...
views.py :
'KnowledgeForm': form,
'errors': str(form.errors),
but then in Django-template I have to use if for each field and im adding custom name for each field , i dont know why i cant use Verbose_name...
Template :
{% if errors %}
<div class="alert alert-danger">
<p>
{% if KnowledgeForm.errors.KnowledgeTitle %}
عنوان دانش: {{ KnowledgeForm.errors.KnowledgeTitle }}
{% endif %}
{% if KnowledgeForm.errors.KnowledgeTextSummary %}
Summary: {{ KnowledgeForm.errors.KnowledgeTextSummary }}
{% endif %}
{% if KnowledgeForm.errors.KnowledgeFromDate %}
from Date: {{ KnowledgeForm.errors.KnowledgeFromDate }}
{% endif %}
{% if KnowledgeForm.errors.KnowledgetoDate %}
To date : {{ KnowledgeForm.errors.KnowledgetoDate }}
{% endif %}
{% if KnowledgeForm.errors.KnowledgeProcess %}
Chart: {{ KnowledgeForm.errors.KnowledgeProcess }}
{% endif %}
{% endif %}
</p>
</div>
{% endif %}
Second method :
{% if KnowledgeForm.errors %}
<ul class="alert alert-danger">
{% for key,value in KnowledgeForm.errors.items %}
<li>{{ key|escape }} : {{ value|escape }}</li>
{% endfor %}
</ul>
{% endif %}
in this method i get the name based on whats used in models.py how can i change it?
The most clear and concise way is to use a forloop
Try replacing your entire if block in your HTML with the below code
{% for field in KnowledgeForm %}
{% if field.errors %}
<div class="alert alert-danger">
{{ field.label_tag }} {{ field.errors }}
</div>
{% endf %}
{% endfor %}
I don't think you need 'errors': str(form.errors),
It is because you convert errors to str and you don't need to separate this.
In your template:
# if you want to use verbose_name just use label_tag.
# label_tag is equal to your verbose name.
{% for field in KnowledgeForm %}
<div class="fieldWrapper">
{{ field.errors }}
{{ field.label_tag }} {{ field }}
</div>
{% endfor %}
So you have the error top of input
Assume I've created a search views with chain (multiple search from different app).
I want to display my result at the same place:
{% for object in object_list %}
{% with object|class_name as klass %}
{% if klass == 'Post' %}
{{ object.title }}
{% elif klass == 'Catego' %}
{{ object.name }}
{% elif klass == 'UserProfile' %}
{{ object.user.username }}
{% else %}
{% endif %}
{% endwith %}
{% empty %}
{% endfor %}
Everything is ok. I got all of my result.
Now, if I want to separate this result in different div (row and collapse class).
If I try this:
<div class="row collapse" id="collapseNutri">
{% for object in object_list %}
{% with object|class_name as klass %}
{% if klass == 'Post' %}
{{ object.title }}
{% endif %}
{% endwith %}
{% endfor %}
</div>
<div class="row collapse" id="collapseCatego">
{% for object in object_list %}
{% with object|class_name as klass %}
{% if klass == 'Catego' %}
{{ object.name }}
{% endif %}
{% endwith %}
{% endfor %}
</div>
<div class="row collapse" id="collapseUserProfile">
{% for object in object_list %}
{% with object|class_name as klass %}
{% if klass == 'UserProfile' %}
{{ object.user.username }}
{% else %}
{% endif %}
{% endwith %}
{% empty %}
{% endfor %}
</div>
I only got the Post result... I'm beginning with Django. Does anyone has an idea to separate search result in order to add different html presentation?
I am having a problem and need your help.

My form in Flask WTF looks like this:
class PublishForm(Form):
tweet = TextAreaField('tweet', [validators.DataRequired(), validators.Length(123, 123)])
When I show the error in template, I don't get the actual length shown. Any idea how to achieve this?
<div class="alert alert-danger">
{% for field in form.errors %}
{% for error in form.errors[field] %}
{{ error }}
{% endfor %}
{% endfor %}
</div>
I ended up fixing it like this:
{% if form.errors %}
<div class="alert alert-danger">
{% set count = form.tweet.data|length %}
{% for field in form.errors %}
{% for error in form.errors[field] %}
{{ error }}
Actual Length: {{ count }}
{% endfor %}
{% endfor %}
</div>
{% endif %}
I generate the following table using django_table2
Semester Actual Prediction
Spring 2014 209 199
*1 coe
The semester, actual, and prediction are column names. My table is exactly how i need it. However, at the bottom of each table I always have the number of items in my model. I do not want that bullet. I know its default in django_table2. Is there a way to remove this? Below is another example:
Department Semester Actual Prediction
MIE 2014 Spring 202 210
MIE 2015 Fall 213 200
MIE 2015 Spring 11 12
*3 departments
The easiest way to do it (for me) is by creating this path (your_templates_dir/django_tables2/tables.html) on your templates directory with the following content:
{% spaceless %}
{% load django_tables2 %}
{% load i18n %}
{% if table.page %}
<div class="table-container">
{% endif %}
{% block table %}
<table{% if table.attrs %} {{ table.attrs.as_html }}{% endif %}>
{% nospaceless %}
{% block table.thead %}
<thead>
<tr>
{% for column in table.columns %}
{% if column.orderable %}
<th {{ column.attrs.th.as_html }}>{{ column.header }}</th>
{% else %}
<th {{ column.attrs.th.as_html }}>{{ column.header }}</th>
{% endif %}
{% endfor %}
</tr>
</thead>
{% endblock table.thead %}
{% block table.tbody %}
<tbody>
{% for row in table.page.object_list|default:table.rows %} {# support pagination #}
{% block table.tbody.row %}
<tr class="{{ forloop.counter|divisibleby:2|yesno:"even,odd" }}"> {# avoid cycle for Django 1.2-1.6 compatibility #}
{% for column, cell in row.items %}
<td {{ column.attrs.td.as_html }}>{% if column.localize == None %}{{ cell }}{% else %}{% if column.localize %}{{ cell|localize }}{% else %}{{ cell|unlocalize }}{% endif %}{% endif %}</td>
{% endfor %}
</tr>
{% endblock table.tbody.row %}
{% empty %}
{% if table.empty_text %}
{% block table.tbody.empty_text %}
<tr><td colspan="{{ table.columns|length }}">{{ table.empty_text }}</td></tr>
{% endblock table.tbody.empty_text %}
{% endif %}
{% endfor %}
</tbody>
{% endblock table.tbody %}
{% block table.tfoot %}
<tfoot></tfoot>
{% endblock table.tfoot %}
{% endnospaceless %}
</table>
{% endblock table %}
{% if table.page %}
{% with table.page.paginator.count as total %}
{% with table.page.object_list|length as count %}
{% block pagination %}
<ul class="pagination">
{% if table.page.has_previous %}
{% nospaceless %}{% block pagination.previous %}<li class="previous">{% trans "Previous" %}</li>{% endblock pagination.previous %}{% endnospaceless %}
{% endif %}
{% if table.page.has_previous or table.page.has_next %}
{% nospaceless %}{% block pagination.current %}<li class="current">{% blocktrans with table.page.number as current and table.paginator.num_pages as total %}Page {{ current }} of {{ total }}{% endblocktrans %}</li>{% endblock pagination.current %}{% endnospaceless %}
{% endif %}
{% if table.page.has_next %}
{% nospaceless %}{% block pagination.next %}<li class="next">{% trans "Next" %}</li>{% endblock pagination.next %}{% endnospaceless %}
{% endif %}
</ul>
{% endblock pagination %}
{% endwith %}
{% endwith %}
</div>
{% endif %}
{% endspaceless %}
This approach will override all of the tables you create via django_table2 template tag and won't necessary work with upcoming versions of django_table2, but I'll be OK if you want to keep an specific version (in my case 0.15.0).
Another approach, which is more scalable, should work with future versions (and I recommend) is by subclassing Table, like described on the django-tables2 documentation.
