Rails控制器Def创建在保存时重定向到URL

Question

def create
  @purchase = Purchase.new(params[:purchase])
  if session[:purchase_id] != @purchase.save
    redirect_to(@purchase, :notice => "Thank you. You good lookin person you.")
  end
end

我正在尝试

A -重定向到URL，或其他控制器路径，或

B -刷新他们订购的表单(new_purchases_path)并flash:通知用户他们的购买成功了。当我尝试添加一个Url(这将是一个感谢消息页)我得到语法错误。此代码将用户重定向到索引列表(用户无法访问)

如果我取出def create，默认情况下它会闪烁一个通知并显示他们完成的表单。我正在使用simple_form，我不确定如何覆盖这些默认值。有什么建议至少重定向到一个url吗?

Answer 1

示例:

A -重定向到URL或其他控制器路径

  redirect_to :action => "show", :id => 5
  redirect_to "http://www.rubyonrails.org"
  redirect_to  new_purchases_path
  redirect_to  purchases_url
  redirect_to :back

B -刷新他们订购的表单(new_purchases_path)

  render :action => "new"

编辑:

这里有一个flash消息的通用示例:

if @foo.save
  redirect_to foos_path, :notice => "Foo saved"
else
  flash[:notice] = "Some errors occured"
  render :action => "new"
end

Answer 2

这是我今天创建的一个create方法的例子

def create
 @book = Book.new(params[:book])
 if @book.save
  redirect_to searchbook_path, notice: 'Book was successfully saved'
 else
render :action => 'results'
end

结束

你可以试试这个

def create
@purchase = Purchase.new(params[:purchase])
if @purchase.save
 redirect_to purchase_path, :notice 'Thanks for your purchase'
else
render :action => 'new'
end
end

这是假设你有一个购买和新的路径…不过如果你能告诉我们你得到了什么错误就更好了
