Question

我已经阅读过有关此错误的问题的先前答案，但我似乎无法使其适应我目前的情况。

我正在完成Tuts + Riding Ruby on Rails课程的i18N部分（将我的代码与course repo中的内容进行比较），并且我必须将默认语言环境更改为葡萄牙语（pt），并更改路由，以便我的问题和项目资源以区域设置（例如localhost3000/pt/issues/14）为前缀，在我的路径文件中/:locale范围内。

由于某种原因，似乎ID键被替换为语言环境哈希。当我提交新问题时，我收到以下错误：

ActionController::UrlGenerationError in Issues#show
Showing /Users/andrekibbe/code/new_issues/app/views/issues/show.html.erb where line #19 raised:
No route matches {:action=>"show", :controller=>"projects", :id=>nil, :locale=>#<Project id: 1, name: "First project", description: "A little description", created_at: "2015-06-20 15:34:58", updated_at: "2015-06-20 15:34:58">} missing required keys: [:id]

我做错了什么？我有正确的路径名吗？

提取的来源（第19行）：

<p><b>Project: </b>
<%= link_to @issue.project.name, @issue.project %></p>

<%= link_to 'Edit', edit_issue_path(@issue) %> |
<%= link_to 'Back', issues_path %>

问题/ show.html.erb

<p id="notice"><%= notice %></p>

<p>
  <strong>Title:</strong>
  <%= @issue.title %>
</p>

<p>
  <strong>Description:</strong>
  <%= @issue.description %>
</p>

<p>
  <strong>No followers:</strong>
  <%= @issue.no_followers %>
</p>

<p><b>Project: </b>
<%= link_to @issue.project.name, @issue.project %></p>

<%= link_to 'Edit', edit_issue_path(@issue) %> |
<%= link_to 'Back', issues_path %>

以下是问题和项目控制器的create操作：

issues_controller.rb

def create
  @issue = Issue.new(issue_params)

  respond_to do |format|
    if @issue.save
      format.html { redirect_to @issue, notice: t('issues.created') }
      format.json { render :show, status: :created, location: @issue }
    else
      format.html { render :new }
      format.json { render json: @issue.errors, status: :unprocessable_entity }
    end
  end
end

projects_controller.rb

def create
  @project = Project.new(project_params)

  respond_to do |format|
    if @project.save
      format.html { redirect_to @project, notice: 'Project was successfully created.' }
      format.json { render :show, status: :created, location: @project }
    else
      format.html { render :new }
      format.json { render json: @project.errors, status: :unprocessable_entity }
    end
  end
end

@Pavan要求的我的问题控制器的show方法是Rails默认值。在这里看不多。

issues_controller.rb

def show
end

我的路线：

的routes.rb

Rails.application.routes.draw do
  scope "/:locale" do
    get 'timeline/index'

    resources :projects
    resources :issues
  end
end

佣金路线

timeline_index GET    /:locale/timeline/index(.:format)    timeline#index
      projects GET    /:locale/projects(.:format)          projects#index
               POST   /:locale/projects(.:format)          projects#create
   new_project GET    /:locale/projects/new(.:format)      projects#new
  edit_project GET    /:locale/projects/:id/edit(.:format) projects#edit
       project GET    /:locale/projects/:id(.:format)      projects#show
               PATCH  /:locale/projects/:id(.:format)      projects#update
               PUT    /:locale/projects/:id(.:format)      projects#update
               DELETE /:locale/projects/:id(.:format)      projects#destroy
        issues GET    /:locale/issues(.:format)            issues#index
               POST   /:locale/issues(.:format)            issues#create
     new_issue GET    /:locale/issues/new(.:format)        issues#new
    edit_issue GET    /:locale/issues/:id/edit(.:format)   issues#edit
         issue GET    /:locale/issues/:id(.:format)        issues#show
               PATCH  /:locale/issues/:id(.:format)        issues#update
               PUT    /:locale/issues/:id(.:format)        issues#update
               DELETE /:locale/issues/:id(.:format)        issues#destroy

我将路径更改为@nathanvda建议的路径，但是建议从Rails框架代码本身中产生了以下错误消息：

NoMethodError in IssuesController#index
undefined method `set_locale' for #<IssuesController:0x007fd2f9fc2460>
Extracted source (around line #432):

case filter
    when Symbol
      lambda { |target, _, &blk| target.send filter, &blk }
    when String
      l = eval "lambda { |value| #{filter} }"
      lambda { |target, value| target.instance_exec(value, &l) }

Answer 1

由于您在区域设置下设置了所有内容，因此rails路径助手假定第一个帮助器是区域设置。

如果您按如下方式编写链接，那么您应该很好：

link_to @issue.project.name, [I18n.locale, @issue.project]

但这似乎有点单调乏味。更好的是来自I18n guides的提示：将区域设置添加到默认网址选项，将以下方法添加到ApplicationController：

def default_url_options(options = {})
  { locale: I18n.locale }.merge options
end

然后你的链接应该按原样运行。

Answer 2

与我相同。旧代码是

<%= link_to "Click Here to reset your password", edit_password_reset_url(@user.password_reset_token), target: :_blank %>

我通过此更新对其进行了修复

<%= link_to "Click Here to reset your password", edit_password_reset_url(I18n.locale, @user.password_reset_token), target: :_blank %>

感谢@nathanvda
