I am making an library app which has two models
Suggestion model is used to suggest books to be added to the library.
Now in the
Suggestion model, I have added a method to retrieve the book and I wish to add this book into the database.
The Code for the above are as follows:
def get_book h = as_json h.delete("id") h.delete("created_at") h.delete("updated_at") return Book.new(h) end
def approve @book = @suggestion.get_book redirect_to @book, notice: "Book was successfully added into the database"
But since the
@book has not been assigned the
id, it is not able to redirect it.
All the other controllers and models are initiated via scaffolding.
How should I retain the information contained in the suggestion and pass it to book controller to add into the database.
You can redirect to new book instead newly created. New book properties You can pass via
redirect_to, for example:
redirect_to new_book_path, notice: "Book was successfully added into the database", new_book: @book.to_json
new_book parameter in
def new if params[:new_book].nil? # usual behavior else @book = Book.new(params[:new_book]) end end
