Can someone give an opinion whether this is a dumb approach?
I want to generate a list of OPTION elements for s SELECT element, but
I can't see any (clean) way to use a template on a list of values
(other than building HTML outside of the template, which is what I'm
trying to avoid). This is what I came up with.
It uses three template files and the .py file. The trick (for lack of a
better word) is to nest a template inside of itself. Looks a little
lispish to me :^)
It might not be a good idea for really long lists, but a SELECT
shouldn't have all that many options anyway.
########## index.py ##########
from mod_python import psp
def test(req):
...
...nested =''
...
...for x in range(10):
.....nested = psp.PSP(req, filename='opt2.tmpl',
......................vars={'val1': nested,
............................'val2': psp.PSP(req, filename='opt.tmpl',
............................................vars={'val':x})})
...tmpl = psp.PSP(req, filename='seltest.tmpl')
...tmpl.run(vars = {'options': nested})
...return
######## seltest.tmpl ###########
<html>
<h2>Test of Select</h2>
<select>
<%= options %>
</select>
</html>
######### opt2.tmpl ###########
<%= val1 %>
<%= val2 %>
######### opt.tmpl ############
<option><%= val %></option>
