Ruby on rails Rails 6-渲染JS失败

我在Rails 6上启动了一个新项目。我在呈现JS文件时遇到了一个问题

def创建
@成员=成员。新建（成员参数）
如果@member.save
将\u重定向到成员\u路径
其他的
render js:：新建
结束
结束

一旦保存操作失败，我想重新编写新的.js.erb文件，但却出现了与我的项目文件无关的奇怪错误

TypeError (no implicit conversion of Symbol into String):

body.each do |part|
  parts << part
  (digest ||= Digest::SHA256.new) << part unless part.empty?
end

[digest && digest.hexdigest.byteslice(0, 32), parts]

有人遇到过这个问题吗？

我认为你做得不对。试试下面这样-

respond_to do |format|
  if @member.save
    return redirect_to members_path
  else
    format.js { render :new }
  end
end

是的，我以前做得不对。此外，值得一提的是，表单中需要

remote:true

，然后只需

render:new

就足够了
