I'm creating my first Rails app and need an idea creating forms.
I have Meeting model with place attribute.
I want to have two fields for Meeting.place = one would be select with
places from other meetings or text_field if the place is being used
first time. User would be selecting radio_button of which field he has
used.
So is there any way to nest select and text_field within 2
radio_buttons?
I would appreciate any other solution ideas too.
Cheers
Here's how I usually solve this (requires Prototype, you'll have to
translate if you're using jQuery):
<script type="text/javascript>
if($('user_practice_id')){
$('user_practice_id').options[$('user_practice_id').options.length]
= new Option('New...','New...');
$('user_practice_id').observe('change',function(evt){
if($F(this) == 'New...'){
var text_input = new Element('input',
{type:'text',size:'60',name:'practice_name',id:'practice_name'});
this.insert({before:text_input});
text_input.focus();
text_input['_bak'] = $
('user_practice_id').hide().options.selectedIndex = 0;
text_input.observe('blur',function(evt){
if($F(this) == '' && this._bak){
this._bak.show();
this.remove();
}
});
}
});
}
</script>
In the controller, I test for the presence of the practice_name
attribute, and if it's there, create a new Practice before assigning
the practice to the User.
if( params[:practice_name] )
practice = Practice.create({:name => params['practice_name']})
params[:user][:practice_id] = practice.id
end
# regular save/update here
This gets you a "combo-box", where you can choose, or add new, in one
interface "slot".
