Cookbook from HELLLLLLLLL

I'm afraid I approached the forms in a horribly wrong way. I know we were supposed to use form_tags, but I couldn't make sense of that approach when trying to add in Measurements or create the edit form, so I ended up manually putting my Measurements and Ingredients in with the form_for. 

I also deleted Measurements objects when editing them and then just creating new ones because it made more sense to me. 

Please show me the way.
Feel free to delete these files if you don't need them.
