Utilizing Django templates to implement custom filters within CSS styling

@register.filter(name='cf')
def formattedAmount(amount):
    # Convert the numerical amount to a string with comma formatting
    formatted_amount = f"{int(amount):,}"

    # Determine if the number is positive or negative and set CSS class accordingly
    if amount < 0:
        css_class = "red-text"
    else:
        css_class = "green-text"

    print(formatted_amount)
    # Generate HTML markup with CSS class and formatted amount
    return f'<span class="{css_class}">{formatted_amount}</span>'

I am using the custom filter in my HTML code, expecting the output to be:

<span class="green-text">5,492</span>

However, the actual output is different than expected.

Please advise me on how to correct this issue.

Answer №1

To ensure proper rendering in Django templates, use the mark_safe function on strings.

from django.utils.safestring import mark_safe

@register.filter(name='cf')
def cf(amount):
   # Format the amount as an integer with commas
    formatted_amount = f"{int(amount):,}"

    # Determine the CSS class based on the sign of the amount
    if amount < 0:
       css_class = "red-text"
    else:
        css_class = "green-text"

    print(formatted_amount)
    # Generate the HTML markup with the CSS class and formatted amount
    return mark_safe(f'<span class="{css_class}">{formatted_amount}</span>')
