Hello,

$ ruby script/generate model balance plus:integer minus:integer  
equal:integer

$ cat app/models/balance.rb  
class Balance \< ActiveRecord::Base  
def save  
self.equal = self.plus - self.minus  
super  
end  
end

$ cat test/fixtures/balances.yml  
\_10-1:  
plus: 10  
minus: 1

$ rake db:fixtures:load

$ sqlite3 db/development.sqlite3  
sqlite\> select \* from balances;  
//=\> |xxx|10|1||…  
// equal is not 9

Even create\_or\_update() was the same.

Should I write it as  
equal: 9  
in the fixture-file?

It’s not DRY.

Thanks.

fixtures are directly inserted into the db

It isn’t, but then again your data just isn’t dry. You can use erb in  
your fixtures ( \<%= %\>) if it’s bothering you that much.

You do understand fixtures are in most cases a bad idea to use.

Thankyou Fernando and Marnen!  
I forget fixtures.  
I will learn Machinist.

Thankyou very much!

Which is one of the many reasons they should never, ever, ever be used.  
The core team completely screwed up the feature. Just forget that  
fixtures exist and use factories (I like Machinist for this). Your  
testing will be much easier.

Best,
