Django Display Objects Data from Database Django.How

Boolean prints in a django template?

  {{ bool_var|yesno:"Agree,Disagree" }}

 

Or

 {% if var == True %} Yes {% else %} No {% endif %}

</code

Default if value evaluates to False (e.g. None, an empty string, 0, False)

{{ profile.user.first_name|default:"--" }}

 

Default_if_none

{{ profile.user.first_name|default_if_none:"--" }}

 

Choice display

 {{ x.get_choices_display }}

 

Filed choice check

 {% if tr_language.language|stringformat:'s'  == 'N' %}
 

 

Checkbox

<br /><br /> <input type=”checkbox” name=”justify” class=”checkbox-md styled-checkbox form-check-input” {% if context.is_justified %} checked {% endif %}><br /><br /> <label for=”justify”>Is justified</label><br /><br />

Select

</p><br /> <div class=”col-2 m-v-05″><br /> <select class=”form-control col m05″ name=”language”><br /><br /> {% for language in languages %}<option value=”{{ language.id }}” {% if tr_language.language|stringformat:’s’ == language.name|stringformat:’s’ %}selected {% endif %} >{{ language.name }}</option>{% endfor %}<br /><br /> </select><br /> </div><br /> <p>

If options are not passed

<option value=”0″ {% if credit_note.tax_type == 0 %}selected {% endif %} >Inland</option>

Field choices with key values

In view

context['unit_choices'] = CompanyService._meta.get_field('unit').choices

 

In template

</p><br /> <div class=”form-group”><br /> <label for=”unit” class=”text-uppercase font-weight-400″>{%trans ‘Price unit:’%}</label><br /><br /> <select name=”unit” id=”unit” class=”form-control” required><br /><br /> {% for key, unit_choice in unit_choices %}<option value=”{{key}}” {% if key|stringformat:’s’ == service.unit|stringformat:’s’ %}selected {% endif %}>{{ unit_choice }}</option>{% endfor %}<br /><br /> </select><br /> </div><br /> <p>

Get value from multiple select

lang_list = request.POST.getlist('languages')
for language in lang_list:
    lang_obj = Language.objects.get(id=language)
    GlossaryLanguage(glossary=p1, language=lang_obj).save()

 

Date and Time

Default input value

<br /><br /> <input type=”date” value=”{{job.create_date|date:’Y-m-d’}}” class=”form-control”><br /><br /> <input type=”time” value=”{{job.create_date|date:’H:i’}}” class=”form-control”><br /><br />

With local time

        {{ request.date_time|localtime|date:'Y-m-d' }} at {{ request.date_time|localtime|date:'H:i' }}

 

Or

        {% with local=request.date_time|localtime %}
            Leave on {{ local|date:'Y-m-d' }} at {{ local|date:'H:i' }}
        {% endwith %}

 

If the date is string you need to convert it to date first in the view

        if isinstance(date_from, str):
            date_from = datetime.strptime(date_from, '%Y-%m-%d')

 

Date with default after 3 days
