Well, I added

model :project  
model :general\_item

to application.rb

But now I get this

NoMethodError in Admin#add\_to\_project

You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occured while evaluating nil.find

Here’s the session dump:

* * *

:project\_in\_progress: &id001 !ruby/object:Project  
attributes: {}  
errors: !ruby/object:ActiveRecord::Errors  
base: \*id001  
errors: {}  
general\_item:  
new\_record: true  
flash: !ruby/hash:ActionController::Flash::FlashHash {}

where does the error occur? could you paste the line of code where the  
nil.find is done

as far as i know the table level operations are static methods, not  
instance  
methods.

@project.find

should be

Project.find

let me know if it helps.
