how to split the string in django template?

Question

i am trying to split the string in template using custom template filter. But i got an error

    TemplateSyntaxError at /job/16/
'for' statements should use the format 'for x in y': for skill in form.instance.skills | split : ","

Here it is my filter

@register.filter(name='split')
def split(value, key):
    """
        Returns the value turned into a list.
    """
    return value.split(key)

this is my template

<h4>Skills</h4>
{% for skill in form.instance.skills | split : "," %}
    {{ skill }}
{% endfor %}

Thanks

Split is a custom filter, don't forget to create your filter, and to load it in your HTML page. Documentation for Django 4.0: https://docs.djangoproject.com/en/4.0/howto/custom-template-tags/

<h4>Skills</h4>
{% with form.instance.skills|split:"," as skills %}
    {% for skill in skills %}
        {{ skill }}<br>
    {% endfor %}
{% endwith %}

It doesn't work due to error Invalid filter: 'split'. Another solution: https://mcmap.net/q/333032/-django-templates-split-string-to-array. – Lemoine

Hum.. did you create the filter in your code? Because split is a custom filter. – Willwilla

For extract character string, use filter cut:

<a href="tel://+1{{ phone|cut:'-' }}">Phone</a>

this removes the scripts from the string.

I was looking around for how to use split filter in Django and i had difficulty to know how to create and register a filter. I tried many solutions till I was able to create a split filter, I am posting here how to do it

In views.py

from django.template.defaulttags import register

@register.filter(name='split')
def split(value, key): 
 
    value.split("key")
    return value.split(key)

and then use it in your HTML as mentioned in the previous very good answers

Hope this helps

The direct for loop works too, you just have to remove the spaces in the syntax:

    <h4>Skills</h4>
            {% for skill in form.instance.skills|split:"," %}
                {{ skill }}
              {% endfor %}
