Django validation array of errors

I am using 

rf['email'].errors

As said in docs, I can use it to have array of errors. 

[str(e) for e in rf['email'].errors]  #give me ["<django.utils.functional.__proxy__>"]

If repr or str - it gives ul's or string of array.

So it worked only when I used repr and eval together. But I think its stupid solution.

eval(`rf['email'].errors`)

You have a couple options depending on the output you'd like.

Option one, use the unicode constructor to convert the data:

list_of_error_texts = [unicode(e) for e in rf['email'].errors]

(Django's proxy object implements a method that responds to unicode.)

Option two, get the ErrorList as text. This produces a newline separated list of error text, with each line preceded by an asterisk:

print rf['email'].errors.as_text()
* My error one
* My error two

Option three, use django's force_unicode function. This is like unicode, but has some extra safety features:

from django.utils.encoding import force_unicode
list_of_error_texts = [force_unicode(e) for e in rf['email'].errors]
