Question about :include_blank => true

Hi All,

When you include the option ":include_blank => true", then the select function includes a blank option. How do you specify text for that option? Many thanks from this newbie for your help!

For instance, rather than getting:

<select name="user[type_id]"> <option></option> <option value="1">admin</option> <option value="2">user</option> </select>

I'd like to get

<select name="user[type_id]"> <option>[Select One]</option> <option value="1">admin</option> <option value="2">user</option> </select>

I think that might defeat the purpose as in your second example if left on the initial selection the form will be submitted with a value of "[Select One]" for that field which is probably not what you want.

What you want is:

<option value="">[Select One]</option>

Which you can do by just making it the first available option.

Thanks for the quick response. But how would you insert that extra option into the select function?

I'd really like to use the following code:

collection_select(:user, :type_id, types, :id, :type, {:include_blank => true})

i'm not sure how to insert an option into the output for this function.

I think you want the :prompt option.
