Insert hyperlink into text using django

I have a variable 'text' in python which contains a very long string. And I have a dict whose key is a word/group of words and value is a url. I need to display this variable 'text' using django, creating hyperlink of all the words/group of words from text which are also there in dict. The link is already stored as value in the dict.

text = "taj mahal is in india"

my_dict = { 'taj mahal':'url1', 'india':'url2' }

Display this text using django where 'taj mahal' and 'india' are hyperlinks to url1 and url2 respectively. I tried to use urlize, but it didn't solve the problem.

You can use replace() on the text variable:

>>> text = "taj mahal is in india"
>>> my_dict = { 'taj mahal':'url1', 'india':'url2' }
>>> for key, value in my_dict.iteritems():
...     text = text.replace(key, value)
... 
>>> text
'url1 is in url2'

or:

>>> text = "taj mahal is in india"
>>> for key, value in my_dict.iteritems():
...     text = text.replace(key, '<a href="%s">key</a>' % value)
... 
>>> text
'<a href="url1">key</a> is in <a href="url2">key</a>'

If you want then to pass this text variable to the template, apply safe filter on it:

{{text|safe}}

Hope that helps.
