New issue 211 by christop...@gmail.com: Cannot access _id and _doc
attributes in a view written in Python
http://code.google.com/p/couchdb-python/issues/detail?id=211
What steps will reproduce the problem?
- Create a view like this:
mapfunc="""
def foo(doc):
yield(doc._id, 42)
"""
- Create a query object like:
q=some_database.query(map_fun=mapfunc)
- The query object gets created properly:
<ViewResults <TemporaryView 'def foo(doc):\n yield(doc._id,42)\n'
None> {}>
- However getting the rows or the number of rows fails:
/home/chaas/projekte/debshots/<ipython-input-82-f16a381fffa4> in <module>()
----> 1 q.total_rows
/usr/lib/pymodules/python2.7/couchdb/client.pyc in total_rows(self)

204 # No more retries, raise last socket error.
--> 205 raise e
206 time.sleep(delay)
207 conn.close()
error: 104
In the /var/log/couchdb/couchdb.log I see a lot of log output. The most
interesting line here probably was:
<<"Traceback (most recent call last):\n File
\"/usr/lib/pymodules/python2.7/couchdb/view.py\", line 78, in map_doc\n
results.append([[key, value] for key, value in function(doc)])\n File
\"<string>\", line 2, in foo\nAttributeError: 'dict' object has no
attribute '_id'\n">>}]}}}]},
It appears as if the attributes starting with "_" are not getting passed
through.

What is the expected output? What do you see instead?
- I expected to get a view of all document IDs (_id) as keys.
- Instead I received an "error: 104".

What version of the product are you using? On what operating system?
