I am geting following error

    def __unicode__(self):
    ^
IndentationError: unexpected indent

Answer 1

Most likely you're using a mix of tabs and spaces in your indentation... Use all spaces / all tabs instead. (The most widely adopted style is to use 4 spaces per level of indent.)

To fix this particular instance of the problem, check make the def __unicode__(self): line start with the same indent as the pub_date = ... line. Use the same indent + four extra spaces for the return ... line.

Answer 2

agree with the others, and you can use editor that can visualize the space to check. e.g. vim set list listchars=tab:»·,trail:· (gedit also has such plugins, i think).
