Body
I'm looking for something similar to how reddit/hackernews specifically (this seems a common approach by a lot of major sites) handle their 'new' listing. It appears to work like so: <ul> <li>when a new link is submitted, a certain number of the latest entries is grabbed</li> <li>those queries are divided up by a PER_PAGE # and cached as cachekey = newestPage1,2,3,4</li> <li>clicking the next/previous buttons loads the next/prev cachekey</li> </ul> My problem is: its difficult to find SQLalchemy/flask-sqlalchemy code for getting a query of only a fixed # of the latest entries. how do I say: <pre><code>q = PostDB.query(order_by('creation_time').desc()).limit(1000) for chunkOf50Results in q: cache.set(CachedChunk+=1, chunkOf50Results) </code></pre> ?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
