[web2py] Re: Filtering tags in crud form dropdowns

[noelrv]

I found that the way to make this work is to set the filtering
(requires directive) in the controller instead of in the model.

 In the models below, each book belongs to a category and has one or
 more tags. Each category has a specified set of tags by defining
 tag.categories as a list:reference.

 The crud form dropdown shows a filtered tag list if I explicitly
 specify a value for contains:
      categorytags = db(db.tag.categories.contains(6))
 but not, if I use:
      categorytags = db(db.tag.categories.contains(db.book.category))

 db.define_table('category',
     Field('name'), format='%(name)s')

 db.define_table('tag',
     Field('name'),
     Field('categories','list:reference category'), format='%(name)s')

 db.define_table('book',
     Field('title'),
     Field('category',db.category),
     Field('tags','list:reference tag'))
 categorytags = db(db.tag.categories.contains(db.book.category))
 db.book.tags.requires=IS_IN_DB(categorytags,'tag.id',db.tag._format,multiple=True)

[web2py] Extra p/p in MARKMIN

Entered using MarkItUp as:

 Use fdisk to create LVM partition
``
+ fdisk /dev/sda
``
Html source in Firefox :

h4Use fdisk to create LVM partition/h4

The p/p above adds an unwanted blank space.

Following reference URL is probably a better and more stable link.
