Something like:
db.mytable.myfield.default = 'some\ntext\nwith\nline\nbreaks'
db.mytable.myfield.represent = lambda v, r: XML(v.replace('\n', '<br />'))
db.mytable.myfield.writable = False
With writable=False, no value will actually be submitted with the form --
the default value will simply be inserted with the new record. However, the
represent function will be used to display the read-only value on the form.
Note, you can also specify the above three attributes directly in the
initial field definition:
db.define_table('mytable',
Field('myfield', default=..., represent=..., writable=False))
Note, in the represent function, it is necessary to wrap the value in XML()
so the <br /> doesn't get escaped when serialized in the response body.
