chemio / chemistry_rails Goto Github PK

I am using your gem, but there is an ortographical error in the vanadium name, because the creators have written venadium instead.

I hope it will be corrected as soon as possible because I need it on my web application.

Thanks!!

Hi, I think this is a great project, but I'm having some trouble installing the gem. When I run rake db:migrate I get this, and it's caused by the chemistry_rails gem

rake aborted!

Check formula like 'C3H6(OH)2' (Propylene Glycol). Creating object with that formula returns

formula = ChemistryRails::Formula.new('C3H6(OH)2')
