Does anyone have experience with using boolean fields (Postgres here, but I
assume it''s the same on MySQL)? Is there any reason the scaffold
generator
explicitly writes out the whole tags rather than use select helpers? It has
a default value specified that does not reflect the DB (always false). The
code is also not XHTML compliant (selected is just selected, not
selected="selected", which seems strange, since as far as I can tell,
usual
generated Rails code seems to be nice and XHTML compliant).
I made my own little true / false option select helper, but it doesn''t
reflect
the database either.
The code was literally cut and pasted from another bit of my app where I use
the same technique to have a select list of options, and that time it does
represent the database perfectly (it''s basically like some kind of enum
list,
which this little true/false selector is too).
But my boolean select thing won''t reflect the database, even though it
does a
perfect job of altering the values when I change them. Here''s the code
-
it''s ridiculously simple, so I have no idea why it''s not
working as I hoped:
def boolean_select(object, fieldname, options ={})
select(object, fieldname, {"True" => "true",
"False" => "false"}, options)
end
I also previously tried:
def boolean_select(object, fieldname, options ={})
select(object, fieldname, %w{true false}, options)
end
It doesn''t work, and I''m puzzled by it!
Best regards,
~Dave

Having the quotes around them effectively turn them into strings and not ruby TrueClass and FalseClass. So just remove that and try again. Other than that I think it should work fine.

Other than that I think it should work fine.Thanks Ezra, the following works perfectly: def boolean_select(object, fieldname, options ={}) select(object, fieldname, {"True" => true, "False" => false}, options) end Cheers, ~Dave -- Dave Silvester Rent-A-Monkey Website Development Web: http://www.rentamonkey.com/
