Question

I am using mezzanine cms. When I scrap the data from the blogspot I got this error

blog_id: sanavitastudio
Traceback (most recent call last):
  File "/home/nyros/hs/git_br/2013/Oct-9/healersource/apps/blog_hs/forms.py", line 226, in save

    description = unicode(self)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 5: ordinal not in range(128)

Code:

            import xmltest
            blog_id = xmltest.blogname(self.cleaned_data['blog_id'])

            print(type(blog_id))
            call_command(
                'import_blogger_hs',
                mezzanine_user=request.user.username,
                blog_id=blog_id)
            return False

And blogname method for If you give blogname it will automatically scrap the blogID and it is represented as blog_id.

Was it helpful?

Solution

Ah, so now with the code the problem is most likely with request.user.username unfortunately the mezzanine code assumes it is receiving an ascii object (what unicode(self) in the stacktrace is doing) and is "double encoding" it... grrr!

I would call your method the same way but do this:

call_command(
    'import_blogger_hs',
    mezzanine_user=request.user.username.decode('utf-8'),
    blog_id=blog_id)

Does that fix the issue?
