As a learning project, I’m using MongoDB with Bottle for a web service. What I want to do is fetch results from MongoDB and display them in a template. Here’s the output I want from my template:
output.tpl
<html><body>
%for record in records:
<li>{{record.city}} {{record.date}}
%end
</body></html>
I can pull the data out no problem:
result = db.records.find(query).limit(3)
return template('records_template', records=result)
But this resulted in no output at all – some debugging shows me that result is some sort of cursor:
<pymongo.cursor.Cursor object at 0x1560dd0>
So I attempted to convert this in to something that the template would like:
result = db.records.find(query).limit(3)
viewmodel=[]
for row in result:
l = dict()
for column in row:
l[str(column)]=row[column]
viewmodel.append(l)
return template('records_template', records=viewmodel)
Debugging shows me that my view data looks OK:
[{'_id': ObjectId('4fe3dfbc62933a0338000001'),
'city': u'CityName',
'date': u'Thursday June 21, 2012'},
{'_id': ObjectId('4fe3dfbd62933a0338000088')
'city': u'CityName',
'date': u'Thursday June 21, 2012'},
{'_id': ObjectId('4fe3dfbd62933a0338000089')
'city': u'CityName',
'date': u'Thursday June 21, 2012'}]
But this is the response I’m getting. Any ideas why?
AttributeError(“‘dict’ object has no attribute ‘city'”,)
Edit: I added that bit about l[str(column)]=row[column] to convert the dictionary keys to non-unicode strings in case that was the problem, but it doesn’t seem to matter either way.
You need to use the dictionary syntax to lookup the properties:
