Good morning,

I have a form with 5 fields. When I click “Save”, 3 of the 5 fields  
save to the database and the other 2 are saved as NULL.

The form code is attached.

The 2 fields that will not save are using collection\_select. On the web  
page I can click on each of the drop down boxes and select an item, but  
for some reason they will not save to the database fields.

Thank you,

Frank

Hard to tell without the matching controller code but I’m guessing  
that your controller code is expecting the collection\_select  
parameters to be in the same place as other ones (ie inside  
params[:time\_subtype], assuming that’s the name of your model) but it  
won’t be because you’re using a raw collection\_select rather than  
form.collection\_select.

I think that :name, :comment, :active\_flag values are stored in the  
params[:time\_subtype] array because text\_field, text\_area and check\_box  
are called on the form object.  
However your collection\_select calls do not refer to the form, so  
they’re not stored in params[:time\_subtype], and if you update your  
object with params[:time\_subtype] as parameter the :entity\_id,  
:time\_type\_id are not found.  
With your code these values are accessible in  
params[:facility][:entity\_id] and parms[:time\_type][:id]. What  
attributes do these two form elements refer to ?

Ahhhh…the form.collection\_select pointed me in the right direction.  
I’ve attached my changes. Thank you Fred & Sébastien for your replys.
