I'm wanting to make a loan from a library book loan,
I made a scaffold for book one for user and one for loan.
In the list of books in each book has a button to lend when I click it takes the id and the name of the book for the loans, in loan will hold the id the name of the book and I will set a user for that loan. >
The problem that I find and make when I lend a book is unavailable to be borrowed and to return this book
NOTE: I have been working with ruby for only two months at a stage, I have never used the language before.
