Question

目标显示页面：

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

但是我没有被带到我自己的goal_path，而是希望被带到我正在看的任何用户的目标显示页面的goals_path。

goals_controller

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

Answer 1

如果您已定义目标用户（或有办法访问用户的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 %>

然后，您可以修改index方法来处理user_id参数：

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

如果他们的id作为param传入，这应该呈现特定用户的目标。希望这有帮助！

你也可以采取一个完全不同的路线，并且更加关注抓取routes.rb，并将其作为路线添加到get "/users/:user_id/goals", to: "goals#user_goals", as: "user_goals" < / p>

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

并更新您的按钮

goals#user_goals

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

def LetterChanges(str)

  str.downcase!
  str = str.split(//)
  alphabet_lower = ["a".."z"]

  i = 0
  letter = 0
  while i < str.length - 1
  if alphabet_lower[letter] == str[i]
    str[i] = alphabet_lower[letter + 1]
    i += 1
    letter = 0 ## Added this for the instance when letter > 0 after an 'else'
  else
    letter += 1
  end
  end

  str = str.join("")
  return str 

end

如何link_to另一个用户的索引？
