Ruby on rails 如何将_链接到其他用户的索引？

在目标显示页面中：

<%= link_to goals_path, class: "btn" do %>
 <span class="glyphicon glyphicon-list"></span> Goals
<% end %>

目标

但是我不想被带到我自己的goals\u路径，而是想被带到我正在查看的任何用户的goals show页面的goals\u路径

目标\u控制器

class GoalsController < ApplicationController
  before_action :set_goal, only: [:show, :edit, :update, :destroy, :like]
  before_action :logged_in_user, only: [:create, :destroy]
  before_action :correct_user, only: [:edit, :update, :destroy]

  def index
    if params[:tag]
      @goals = Goal.tagged_with(params[:tag])
    else
      @accomplished_goals = current_user.goals.accomplished.order("deadline")
      @unaccomplished_goals = current_user.goals.unaccomplished.order("deadline")
    end
  end

  def show
    @goal = Goal.find(params[:id])
    @commentable = @goal
    @comments = @commentable.comments
    @comment = Comment.new
    @notable = @goal
    @notes = @notable.notes
    @note = Note.new
    @correct_user = current_user.goals.find_by(id: params[:id])
  end

  def new
    @goal = current_user.goals.build
  end

  def edit
  end

  def create
    @goal = current_user.goals.build(goal_params)
    if (params[:commit] == 'conceal')
      @goal.conceal = true
      @goal.save
      redirect_to @goal, notice: 'Goal was successfully created'
    elsif
      @goal.save
      track_activity @goal
      redirect_to @goal, notice: 'Goal was successfully created'
    else
      flash.now[:danger] = 'Required Field: "Enter Goal"'
      render 'new'
    end
  end

  def update
    if @goal.update(goal_params)
      redirect_to goals_url, notice: 'Goal was successfully updated'
    else
      render action: 'edit'
  end
end

  def destroy
    @goal.destroy
    redirect_to goals_url
  end

  def like
    @goal = Goal.find(params[:id])
    @goal_like = current_user.goal_likes.build(goal: @goal)
    if @goal_like.save
      @goal.increment!(:likes)
      flash[:success] = 'Thanks for liking!'
    else
      flash[:error] = 'Two many likes'
    end  
      redirect_to(:back)
  end

  private
    def set_goal
      @goal = Goal.find(params[:id])
    end

    def correct_user
      @goal = current_user.goals.find_by(id: params[:id])
      redirect_to root_url, notice: "Not authorized to edit this goal" if @goal.nil?
    end

    def goal_params
      params.require(:goal).permit(:name, :like, :deadline, :accomplished, :tag_list, :comment, :private_submit)
    end
end

class GoalsController

如果您需要进一步的解释或代码来帮助我，请告诉我：-]

如果您定义了目标用户（或有办法访问用户id），您可以执行以下操作：

<% link_to goals_path(user_id: @goal.user_id) do %>
   <span class="glyphicon glyphicon-list"></span> Goals
<% end %>

---

如果将特定用户的id作为参数传入，则应呈现该用户的目标。希望这有帮助

你也可以选择一条完全不同的路线，在抓取

用户/：user_id/goals

时稍加休息，然后将其作为路线添加到你的

路线中。rb

   get "/users/:user_id/goals", to: "goals#user_goals", as: "user_goals"

并更新您的按钮，使

<% link_to user_goals_path(@goal_user) ... %>

非常感谢Zoran，这很有道理！我尝试了

link\u to goals\u path（user\u id:@user.id）

和其他一些变体，但这给了我：

undefined method

id'for nil:NilClass`你有更好的选择吗？@AnthonyGalli.com你需要有一个对用户的引用，也就是说，

@user

需要给定一个值，或者您需要使用其他变量。@Jon它有一个引用。如果我执行rails console Goal.find（1），则会显示附加到它的用户id:

用户id:2，

@AnthonyGalli.com Jon的右侧-您的

显示

操作没有用户定义。您可以尝试在那里定义它，或者用

@goal.user\u id

替换

@some\u user

。我已经更新了我的答案。希望有帮助！抱歉@Zoran这也是我尝试过的事情之一，但这只是让我回到当前用户的目标索引，与以前一样，但现在url显示我可能需要更改配置文件？谢谢帮助！我尝试了您的代码，但出现了错误：

ActionController:：UrlGenerationError in Goals#show No route matches{：action=>“user\u Goals”，：controller=>“Goals”，：user\u id=>nil}缺少必需的键：[：user\u id]

Hmm。。。你试过了吗？

我把方法放在控制器和模型中。不知道在哪里。我还尝试了这一行的变体，正如您所建议的：

<% link_to user_goals_path(@goal_user) ... %>

def user_goals
    @goals = Goal.find_by({user_id: params[:user_id]})
    render :index # or some other view
end
