ruby on rails - Help on Inserting a record to the db -

i insert record db based on values of querystring parameters, @ minute have scaffold methods , works, takes values @ in new method, when sumbit button clicked, inserted db.

how can 'skip' clicking of button, inserted in new method?

code:

@book = book.new(params[:book]) @book = book.new({:user_id=>session[:user_id], :author=>session['test']})  respond_to |format|   if @book.save     format.html { redirect_to(@book, :notice => 'book created.') }     format.xml  { render :xml => @book, :status => :created, :location => @book }   else     format.html { render :action => "new" }     format.xml  { render :xml => @book.errors, :status => :unprocessable_entity }   end end 

put in action want save automatically:

@book = book.new(params[:book]) @book.save 

some thing might want add: save if if params[:book] set:

unless params[:book].blank?   @book = book.new(params[:book])   @book.save end 

also think of error handling. if book not stored?
