problem with select_tag and observe_field

Hello All,

I have problem with select_tag and observe_field. I get following error

" NoMethodError in Businesses#plan_pricing

Showing app/views/businesses/_refresh_subscription_types.html.haml where
line #1 raised:

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.collect"

following is source code

Here i get "@subscription_types" object nil , when I render
"_plan_pricing.html.haml" first time.

Please tell me where i am doing wrong.

Does the plan_pricing action set @subscription_types to something ?

I fixed that syntax error ‘false’ to false but still getting same error

for
= select_tag ‘subscription’,
options_for_select(@subscription_types.collect {|subscription_type| [
subscription_type.title, subscription_type.id ] })

I think this is something to do with brackets and ruby not being able to work out what on earth you’re trying to say.

You have brackets on your inner method, but not your outer method, so ruby requires you put brackets all around everything.

This is, at least, my guess.

Try this:

<%= select_tag(‘subscription’, options_for_select(@subscription_types.collect{|subscription_type| [subscription_type.title, subscription_type.id]})) %>
