A random space being inserted to a UUID for a email link

Question

For whatever reason, a random space is getting inserted in the UUID of a record. I send out emails for people to click on confirm or cancel links to update the records in my database. I use the UUID to make sure they are updating the correct record.

I generate the HTML for the link within my forms.py- If I only have the cancel_donation_link in there, it works fine. Once confirmation link is added. It add a space inbetween the canceled link UUID.

for special_word in values['special_words']:                     
    print special_word                                           
    text = values['text']                                        
    print text                                                   
    uuid = rescheduled_donor.uuid                                

    if special_word == "confirm_donation_link":                  
        values['text'] = text.replace(                           
            special_word,                                        
            '<a href="http://{0}/actions/email_blasts/confirm/' \
            '{1}">Confirm Donation</a>'.format(                  
                domain,                                          
                uuid                                             
            )                                                    
        )                                                        
        values['special_words'].remove(special_word)             
        continue                                                 

     if special_word == "cancel_donation_link":                  
         values['text'] = text.replace(                          
             special_word,                                       
             '<a href="http://{0}/actions/email_blasts/cancel/' \
             '{1}">Cancel</a>'.format(                           
                 domain,                                         
                 uuid                                            
             )                                                   
         )                                                       
         values['special_words'].remove(special_word)    
         continue        

Right before I send off all the context to the email template I print out the html which shows NO space in between the UUID

<div>If you wish to cancel your donation click here:&nbsp; <a href="http://127.0.0.1:8000/actions/ema
il_blasts/cancel/f42f1915-2e6b-401c-bd0f-e99ba54e9ea5">Cancel</a>  </div>

Once the email is sent, the URL has a space in the UUID section. It gets replaced by %20. Cancel

I have no idea why or how this random space is getting inserted.

I ended up changing the string part of my URL to use the reverse function instead of hard coding it. I also noticed a difference from when I had it running locally on my laptop compared to on my staging site on my webfaction server.

if special_word == "cancel_donation_link":                              

    values['text'] = text.replace(                           
        special_word,                                        
        '<a href="{0}{1}">Cancel</a>'.format(                
            domain,                                          
            reverse('email_blasts_cancel', kwargs={'donor_uuid': uuid})
        )                                                    
    )
