I think it is better if you use .join() to concatenate the selectors, or
create a function in a model file to return the properties.
file models/css.py
<code>
def return_css(company_id):
rows = db(....==company_id).select(......)
oldselector = None
css = []
for row in rows:
if row.selector!=oldselector:
css.append(dict(selector=row.selector,\
property=row.property,\
value=row.value
)
)
oldselector=row.selector
code = ''
for c in css:
code = code + '%(selector)s{%(property)s:%(value)s;}' % c
return code
</code>
(may be you need to improve the code above)
and in view you do
{{=return_css(xyz)}}
or in your code in view
{{oldselector=None}}
{{for row in rows}}
{{if row.selector!=oldselector}}
{{=row.selector}} {
{{oldselector=row.selector}}
{{pass}}
{{=row.property}}:{{=row.value:}};
}
{{pass}}
