我很难理解为什么会遇到这个问题。我查看了大多数类似的问题。在大多数情况下，作者忘记包括相关路线。但是我清楚地做了，我把这个问题归结为我的Rails知识中的空白，我希望你们中的一些人可以解决这个问题。
我不断得到的错误：No route matches [GET] "/fight.29"尽管在resources :fights中定义了它，我也尝试了其他方法，但我也没有用。
我注意到的一些事情：
http://localhost:3000/fight.29 http://localhost:3000/fights/29而不是FightsController
http://localhost:3000/fights/29时，它的效果非常好。fights的展示操作缺少前缀.和fight之间29。不确定这意味着什么以及它是否与错误有关以下是rake routes的输出：
Prefix Verb URI Pattern Controller#Action
root GET / static_pages#home
fighter_skills GET /fighters/:fighter_id/skills(.:format) skills#index
POST /fighters/:fighter_id/skills(.:format) skills#create
new_fighter_skill GET /fighters/:fighter_id/skills/new(.:format) skills#new
edit_fighter_skill GET /fighters/:fighter_id/skills/:id/edit(.:format) skills#edit
fighter_skill GET /fighters/:fighter_id/skills/:id(.:format) skills#show
PATCH /fighters/:fighter_id/skills/:id(.:format) skills#update
PUT /fighters/:fighter_id/skills/:id(.:format) skills#update
DELETE /fighters/:fighter_id/skills/:id(.:format) skills#destroy
fighters GET /fighters(.:format) fighters#index
POST /fighters(.:format) fighters#create
new_fighter GET /fighters/new(.:format) fighters#new
edit_fighter GET /fighters/:id/edit(.:format) fighters#edit
fighter GET /fighters/:id(.:format) fighters#show
PATCH /fighters/:id(.:format) fighters#update
PUT /fighters/:id(.:format) fighters#update
DELETE /fighters/:id(.:format) fighters#destroy
fight POST /fight(.:format) fights#start
new_fight GET /fights/new(.:format) fights#new
GET /fights/:id(.:format) fights#show
这是我的routes.rb：
root 'static_pages#home'
resources :fighters do
resources :skills
end
post '/fight', to: 'fights#start'
resources :fights, only: [:new, :show]
#get '/fights/:id/', to: 'fights#show'
#match '/:id' => 'fights#show', via: [:get]
这是fights_controller.rb：
def show
@fight = Fight.find(params[:id])
end
def start
@fight = Fight.create(attacker_id: params[:attacker_id], defender_id: params[:defender_id], winner: params[:winner])
if @fight.save
redirect_to @fight
else
redirect_to root_path
end
end

我错过了什么？
编辑：
<%= link_to 'FIGHT!', fight_path(@fight, attacker_id: @attacker.id,
defender_id: @defender.id,
winner: compare_power_levels(@attacker, @defender)), method: :post %>
注意：compare_power_levels在比较后只返回两个对象中的一个。
答案 0 :(得分：2)
你可以尝试
redirect_to fight_path(@fight)
<%= link_to 'FIGHT!', fight_path(@fight,{ attacker_id: @attacker.id,
defender_id: @defender.id,
winner: compare_power_levels(@attacker, @defender)}), method: :post %>
或

Method: GET
答案 1 :(得分：1)
如果您在点击 link_to 标记时遇到此问题，请检查link_to标记中的路径。
理想情况下，它应如下所示：
<%= link_to 'show', fight_path(@fight) %>
答案 2 :(得分：1)
当rails生成带点的链接是因为您在路径中使用复数，或者任何其他＆＃34;集合＆＃34;路由。
您没有添加link_to，所以我会尝试解决：
<%= link_to 'show', fight_path(@fight) %>
在您的控制器中，您需要使用正确的路径重定向：
redirect_to fight_path(@fight)
答案 3 :(得分：1)
原因在于：
post '/fight', to: 'fights#start'
resources :fights, only: [:new, :show]
post '/fight'生成命名路由fight_path，通常由resources创建。由于已经定义，resources不会覆盖它。您可以在路线中看到：
fight POST /fight(.:format) fights#start
虽然它应该是：
fight GET /fight/:id(.:format) fights#start
由于路线只有一个可选参数:format，因此当您致电fight_path(@user)时，@user.id将用作格式，从而产生'/fight.30'
您需要重命名post '/fight'路线：
post '/fight', to: 'fights#start', :as 'start_fight'
