The problem

I have a model for a league like

class League(models.Model):
 league_name = models.CharField(max_length=60)
 league_url = models.URLField(null=True, blank=True, default='')

where league_url can be a link to an external league page (i.e. not my site).

Now, let's say a user creates a league and sets league_url to "pelicanpark.com/leagues/27". When I render this in a template, league.league_url it shows http://www.pelicanpark.com/leagues/27/ which takes up a lot of real estate.

So, I need to slim it down. My thought is to render something like

<a href="http://www.pelicanpark.com/leagues/27/">pelicanpark.com/...</a>

but this has some obvious complexities. Does anyone have a good solution for this?

There's probably some fancy way of using regex for this kind of thing, but that's above my head. Luckly it looks like there's urlparse for python. To implement it in your example:

from urlparse import urlparse

class League(models.Model):
 league_name = models.CharField(max_length=60)
 league_url = models.URLField(null=True, blank=True, default='')

 def url_text(self):
 parsed_url = urlparse(self.league_url)
 return parsed_url.hostname.replace("www.", "") + "/..."

Then in template:

<a href=" league.league_url "> league.url_text </a>

I would refrain from rendering the html in the backend. I've always been told there's security risks in doing that.

You can create a field with MethodSerializer

class League(models.Model):
 league_name = models.CharField(max_length=60)
 nice_league_url = serializers.SerializerMethodField()


 def get_league_url(self,obj):
 final_url = "<a href="+obj.league_url+">pelicanpark.com/...</a>"
 return final_url

The above answers are spot on. I just ran into the same problem and found some changes. For Python3 and higher, use:

from urllib.parse import urlparse

instead.
