我试图在用户注册验证失败时保持一个漂亮的URL
我有一个类似于以下内容的路由文件:
map.resources :users
map.signup '/signup', :controller => "users", :action => "new"
这很有效,但如果用户在注册期间输入了无效信息,则create方法会执行以下操作:
def create
@user = User.new(params[:user])
if @user.save
flash[:notice] = "Successfully Registered."
redirect_to root_url
else
render :action => 'new'
end
end
这样可行,但如果信息正确,则会将URL切换到domain.com/users。如果我将它切换到redirect_to'/ signup'它可以工作,但输入的所有先前信息都会丢失,我最好还是保留它。
在验证失败期间,有没有办法保留我的网址?

您需要为路线添加条件:
# Routes files
map.resources :users
map.signup "/signup", :controller => "users", :action => "new", :conditions => { :method => :get }
map.signup "/signup", :controller => "users", :action => "create", :conditions => { :method => :post }
然后,您需要确保您的控制器和视图正确处理它们:
# Controller
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
flash[:notice] = "Successfully registered."
redirect_to root_url
else
render "new"
end
end
# new.html.erb
<% form_for @user, :url => signup_path do |form| %>
....
<% end %>

尝试添加路线:
map.signup_post '/signup', :controller => "users", :action => "create", :method => :post
以你的形式:
<%= form_for @user, :url => signup_post_path do |f| %>
