Probably something like this:
@recipes = Category.find_by_name(“sweet”).recipes

Thanks very much David, but i get the followng error, any idea?
undefined method `find_by_name’ for Category:Class
Just figured it out, replace the ‘name’ part, with the field in the
database, thats great, thank you so much.
With
@recipes = Category.find_by_name(“sweet”).recipes
what would i do if i wanted to pass in “sweet” as a variable? can i use
:id with this?

If you are using the normal ID field of a model then you on need
@recipes = Category.find(@params[:id]).recipes
.find works with the ID. The others basically extend the
.find_by_ pattern.
thankyou
