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

Solution 1:

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
from django.contrib import admin

@admin.display(description="Firm URL")
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)
    

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.

Solution 2:

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.

Solution 3:

add show_firm_url to list_display

Solution 4:

You can handle it in the model if you prefer:

In models.py :

class Foo(models.Model):
...


     def full_url(self):
        url = 'http://google.com'
        from django.utils.html import format_html
        return format_html("<a href='%s'>%s</a>" % (url, url))

admin.py:

    list_display = ('full_url', ... )
