我的new.html.erb表单没有发布，也没有在数据库中创建对象。相反，当我单击“提交”按钮时，URL将更改为meds/new?utf8=✓&authenticity_token=<random characters>。看起来它正在尝试进行GET，我认为它应该尝试POST来创建对象。它看起来不像应用程序甚至试图在Controller中调用我的创建操作。这是我在控制台中得到的内容：
Started GET "/meds/new?utf8=%E2%9C%93&authenticity_token=XG44W3%2Bj5A3piAJnp0uQUF8L5gruoGDgdiaqZgCSf3bY219l%2BGIRc4Z%2FaypXa%2FacacQGTCFQmFMckS30Jf6ZLg%3D%3D&med%5Bbrand_name%5D=sfsdf&med%5Bgeneric_name%5D=sdfsdf&med%5Bdescription%5D=sdfsdf&med%5Breactions%5D=&med%5Binteractions%5D=&med%5Bimplementation%5D=&med%5Bavailability%5D=&med%5Bwarnings%5D=&commit=Save+changes" for ::1 at 2015-08-28 22:24:00 -0400
Processing by MedsController#new as HTML
我很确定问题出在我的路线上。我的创建操作甚至没有前缀。以下是运行rake路线的结果：

new_med GET /meds/new(.:format) meds#new

我的路线是否存在问题，或者我错过了其他内容？
谢谢！

问题可能是您的创建方法。我刚刚在我的应用程序中尝试了您的代码，并且像您一样尝试SELECT。试试我在下面写的代码。
@med = Med.new(med_params)
