In the 'StockpotBase' class you set the models as their own parents. It would seem that this would result in an infinite iteration when using authorization; lineage is used to iterate through parents until a resource is found that has an __acl__ member.

Hi there... I am quite new to Python, Pyramid and MongoDB. I tried applying your code you provided as is to new pyramid project I created. I added the dependencies required to run this, and I created a view to login. The error I am getting is: AttributeError: 'str' object has no attribute '_auto_ensure_indexes' it gives the error in models/__init__.py on line 19: "session.ensure_indexes(mapper.collection)" - this is line 19 on your code(this page), can you please help me with this?

Is there a particular reason that you pass the request into the constructor of your root and then assign self.request = request? I'm dealing with some code that does this a lot without ever appearing to use it, and would like to know whether it is required by the framework.

Thanks

Row 8:
engine = sa.create_engine('sqlite:///:memory', echo=True)

should beengine = sa.create_engine('sqlite:///:memory:', echo=True)

Note the additional colon after memory. The first version creates a file named :memory

Sorry about that Paul, this code is old. Take a look at my velruse_demo project on github. It is more up to date. I will also submit an update to the pyramid docs. SorRt this reply is so short, typing it from my phone in the mountains.

The sourceforge link[1] yields 403. What appears to be the same project on github has instructions that reference a development.ini that doesn't exist in the repository. This article is referenced in the pyramid_cookbook doco, so, there is an increased expectation that this blog post would provide some helpful insight rather than a very frustrating pursuit of a stockpot review.

I'm not fluent with SQL Alchemy, but is it possible to group by based on a custom Python function? A unix timestamp has a range of about 12*137 months; an array could be created with the timestamps of the month starts, and the group_by value could be provided by the index in the array, said index discovered by a bisect.bisect lookup.

yeah i wish Ralph had asked me about that, he did a nice job figuring out the reflection part, but he should have gone with TypeDecorator in his approach instead of adapting at the mapper level. He already had a hook into where the type gets set on the Table and he can put it right there !

I wasn't even aware that sourceforge had SVN!

I can honestly not recall ever really seeing SF tooting its own horn, which is kind of surprising what with geeknet also owning slashdot you'd think new/updated features would show up on their sister site more frequently.

Hell, what with berlios shuttering at the end of this year, sourceforge should be going all out to market itself as the best candidate platform to migrate to.

Thanks Robert, I correct the issue. I made the id columns of the models Unicode type and also ensured that index and deindex are using the unicode ID (which is now set to oid, instead of the reserved word id).

Re: Piece Of Py(thon)

Robert Forkel — Tue, 30 Aug 2011 09:21:48 -0000

great writeup. I found a bug in SawhooshBase: In reindex and deindex you do not actually use the unicode-formatted id, but self.id (which won't work if self.id cannot be forced to unicode).

It depends, if you are using the results for auto-completion and the results are coming from multiple tables and you are doing full table scans to locate the results, then yes, you would benefit from a search index for your data.

That's great!! I am currently working on a pyramid project. I am new to python and this is the first time I hear of whoosh. Your code approach is great and I might use it on my project. :)

I currently directly query the database for "ajax autocomplete" searches, and I wonder if it is a better approach to use a search index for example whoosh insteaad of querying the sqlalchemy models. What do you think?
