Rails options_for_select with selected model value -

there following code:

f.select     :engine_value, options_for_select(engine_values_select_items)

as can see, it's select list options. problem if form object has got float value in engine_value value not selected in select tag. how can fix this?

code engine_values_select_items:

def engine_values_select_items     (1..6).step(0.1).to_a.map{|s| [s.round(2), s.round(2)]} end

i thought rails did default, perhaps wrong?

i can remember myself dealing issues. imho in cases approach followed meet expectations similar "generators" , combinations of them.

there another post might you.

also not forget check out proper syntax (i talking order).

then, try using "selected: " see how go.

hope helps,
