Can't open worksheet without edit permissions

[anentropic]

I wanted to import data from a spreadsheet where I had view only, no edit permissions.

I was able to get_doc successfully but when I try to get_worksheet I get the following error:

/myproject/lib/python2.7/site-packages/gspread/models.pyc in get_worksheet(self, index)
    146         """
    147         if not self._sheet_list:
--> 148             self._fetch_sheets()
    149         try:
    150             return self._sheet_list[index]

/myproject/lib/python2.7/site-packages/gspread/models.pyc in _fetch_sheets(self)
     64         feed = self.client.get_worksheets_feed(self)
     65         for elem in feed.findall(_ns('entry')):
---> 66             self._sheet_list.append(Worksheet(self, elem))
     67
     68     def add_worksheet(self, title, rows, cols):

/myproject/lib/python2.7/site-packages/gspread/models.pyc in __init__(self, spreadsheet, element)
    168         self._element = element
    169         self.version = self._get_link(
--> 170             'edit', element).get('href').split('/')[-1]
    171
    172     def __repr__(self):

    209     def _get_link(self, link_type, feed):
    210         return finditem(lambda x: x.get('rel') == link_type,
--> 211                         feed.findall(_ns('link')))
    212
    213     def _fetch_cells(self):

/myproject/lib/python2.7/site-packages/gspread/utils.pyc in finditem(func, seq)
     16
     17     """
---> 18     return next((item for item in seq if func(item)))
     19
     20

StopIteration:

If I save a copy of the spreadsheet and open the copy, where I am owner with edit permissions, then I can get_worksheet successfully. So I believe it is due to permissions.

I realise may not be possible due to Google API, but I'd hoped to still be able to do non-editing operations.

Duplicate of #175. This behavior is currently unsupported but we're working towards adding it.
