我正在尝试按照教程在 ruby on rails (http://www.youtube.com/watch?v=oXr1jAsBlPI&feature=relmfu) 中制作 Twitter 克隆。对我来说不幸的是,他在 Rails 2.xx 中这样做,我在跟上时遇到了一些麻烦。我目前是 41:34,当时他正在定义routes.rb
.
当我进入我的“显示”页面时,我遇到了这个问题:
“路由错误没有路由匹配 {:action=>"show", :controller=>"toggle_follow"} 尝试运行 rake 路由以获取有关可用路由的更多信息。”
这是我在相关文件中的内容:
路线.rb
match '/:username', :controller => 'home', :action => 'show'
match '/:username/toggle_follow', :controller => 'home', :action => 'toggle_follow'
显示.html.rb
<% if current_user.is_friend? @user %>
<%= submit_tag "Following", :class => "button" %>
<% else %>
<%= submit_tag "Stop following", :class => "button" %>
<% end %>
home_controller.rb
def show
@user = User.find_by_username(params[:username])
@flits = @user.all_flits
end
def toggle_follow
@user = User.find_by_username(params[:username])
if current_user.is_friend? @user
flash[:notice] = "You are no longer following @#{@user.username}"
current_user.remove_friend(@user)
else
current_user.add_friend(@user)
flash[:notice] = "You are following @#{@user.username}"
end
redirect_to user_flits_path(@user.username)
end
