RUM can also be used to develop web applications: [wiki:MoreThanCrud]. It is designed to keep simple things simple and difficult things possible: [wiki:SortByRelation]

Is is also possible to enrich RUM applications by calls of a WebService to other resources. Further more sophisticated LayoutModifications are possible.
It integrates well with SQLAlchemys facilities for AdvancedDataMapping.

=== Reorder the automatically generated fields ===

{{{
paster shell ...
}}}

{{{
#!python
fields=[f.name for f in app.fields_for_resource(Document)]

In [13]: page fields
['occasion',
 'document_type',
 u'document_id',
 u'document_type_id',
 u'content',
 u'occasion_id',
 u'remark']
}}}
Copy that list to your code and reorder it:
{{{
#!python
FieldFactory.fields(Document,
[
 'document_type',
 'occasion',
 'document_id',
 'document_type_id',
 'content',
 'occasion_id',
 'remark']
)
}}}
Using that list the fields will still be automatically generated and automatically update to model changes.
Of course, you can still explicitely instiate fields here, or add new ones (not detected by RUM).

In my case, I added a size field, which originates from a SA column property:

{{{
#!python
FieldFactory.fields(Document,
[ 
 Integer('size', read_only=True),
 'document_type',
 'occasion',
 'document_id',
 'document_type_id',
 'content',
 'occasion_id',
 'remark']
)
}}}
