impossible to use boolean indexes

[Viesturs Teivāns]

Hello, I am using u1db for my Ubuntu app and I wanted to use an index with Boolean value, like in the tutorial (cosas), but it seems not to be passable to get documents by boolean index.

So i define the indexes
LAST_INDEX = 'last'
...
INDEXES = {
 LAST_INDEX: ['bool(last)']
...
}

And create them in for loop just like in tutorial:
for name, expression in INDEXES.items():
 self.db.create_index(name, *expression)

So far so good
but when I try to get something from boolean index, like this:
db.get_from_index(LAST_INDEX, True)

I get an error:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/u1db/backends/sqlite_backend.py", line 670, in get_from_index
    statement, args = self._format_query(definition, key_values)
  File "/usr/lib/python2.7/dist-packages/u1db/backends/sqlite_backend.py", line 641, in _format_query
    if value.endswith('*'):
AttributeError: 'bool' object has no attribute 'endswith'

but if I take all elements from index like in tutorial:
db.get_from_index(LAST_INDEX, '*')
it returns all just fine

Thanks for your report. We will be looking into it next week.

the documentation is not clear on this point (we will improve it) but the current version of get_from_index takes always strings for values

so a bool(.) index needs to be queried with:

get_from_index(LAST_INDEX, "0"|"1") where "0" is false and "1" is for true,

similarly for a number(.) index

Thanks for your replay. I only tried "True" and "False" like strings.
