I'm haviing an issue adding a constant to a model though a decorator, just testes in the Rails console and seems is not loading it:
```2.6.6 (console)[3] » Spree::Product::SEARCHER_STRING_LIMIT
NameError: uninitialized constant Spree::Product::SEARCHER_STRING_LIMIT```
am I missing something else?
Thanks.

I can't tell why your code isn't working if you don't show the code. :sweat_smile:

My guess is you need to use include/prepend rather than class_eval, but I'd need to see your decorator to know for sure.

constants (and constant lookup) in Ruby work very differently than many other languages. `class_eval` is changes the current class and sets `self` to it, but doesn't affect the scope as far as constants are concerned

yes, I'm using `class_eval`
```Spree::Product.class_eval do
  SEARCHER_STRING_LIMIT = 160
  ...
end```

For starters: using class eval is discouraged. You should use include or prepend. It will work if you switch to that. 

Alternatively, set the constant like `Spree::Product::SEARCHER_STRING_LIMIT = 160`
