## event\_behavior.rb

class EventBehavior \< Behavior::Base

register ‘Event’

description = %{}

define\_tags do  
tag ‘event’ do |tag|  
if tag.attr[‘find’]  
tag.locals.event = Event.find\_by\_name(tag.attr[‘find’])  
end

```
  tag.expand
end

tag 'event:name' do |tag|
  tag.locals.event.name
end

```

end

end

## Radiant page:

\<r:event find=“Celine Dion”\>

* * *

Okay. So, the example above works. However… One seemingly simple  
change…

## event\_behavior.rb

class EventBehavior \< Behavior::Base

register ‘Event’

description = %{}

define\_tags do  
tag ‘event’ do |tag|  
tag.locals.event = Event.find\_by\_name(tag.attr[‘find’])  
tag.expand  
end

```
tag 'event:name' do |tag|
  tag.locals.event.name
end

```

end

end

* * *

And everything goes to shit. I get:  
You have a nil object when you didn’t expect it! The error occured while  
evaluating nil.name

Hitting refresh gives me a Rails error – I assume it’s because of  
Radiant’s  
caching.

Since when did evaluation for truth alter the way something behaves?

Help is greatly appreciated.

Update…

Looks like the query is being run twice.

My development log says…

* * *

Event Load (0.000271) SELECT \* FROM events WHERE (name = ‘Celine  
Dion’)  
LIMIT 1  
Event Columns (0.000165) SHOW FIELDS FROM events

Logger: Found record: Celine Dion

## Event Load (0.000187) SELECT \* FROM events WHERE (name = NULL) LIMIT 1

For whatever reason it’s doing the find twice. Any ideas?
