How to add clickable links to a field in Django admin?


I have this

class LawyerAdmin(admin.ModelAdmin):
    fieldsets = [
        ('Name',   {'fields': ['last', 'first', 'firm_name', 'firm_url', 'school', 'year_graduated']}),
    list_display = ('last', 'first', 'school', 'year_graduated', 'firm_name', 'firm_url')
    list_filter = ['school', 'year_graduated']
    search_fields = ['last', 'school', 'firm_name']

and I want to make "firm_url" fields clickable with each of the url listed in the field. How can I do this? Thank you.

Define a custom method in your LawyerAdmin class that returns the link as HTML:

def show_firm_url(self, obj):
    return '<a href="%s">%s</a>' % (obj.firm_url, obj.firm_url)
show_firm_url.allow_tags = True

See the documentation.

Use the format_html utility. This will escape any html from parameters and mark the string as safe to use in templates. The allow_tags method attribute has been deprecated in Django 1.9.

from django.utils.html import format_html

class LawyerAdmin(admin.ModelAdmin):
    list_display = ['show_firm_url', ...]

    def show_firm_url(self, obj):
        return format_html("<a href='{url}'>{url}</a>", url=obj.firm_url)

    show_firm_url.short_description = "Firm URL"

Now your admin users are safe even in the case of:

firm_url == 'http://a.aa/<script>eval(...);</script>'

See the documentation for more info.
