Question

为了路由编辑当前用户的个人资料，我需要使用哪种语法？我想在我的页面上添加一个链接，用于编辑您的用户个人资料。我知道如何link_to但不确定语法是什么来获得当前用户。

<%= link_to "Edit Profile", current_user %>

我的UsersController看起来像这样：

class UsersController < ApplicationController
  before_action :logged_in_user, only: [:index, :edit, :update, :destroy]
  before_action :correct_user,   only: [:edit, :update]
  before_action :admin_user,     only: :destroy


  def index
    @users = User.paginate(page: params[:page])
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)

    if @user.save
        flash[:notice] = "Welcome to Studio Academy Manager"
      sign_in @user
        redirect_to root_url
    else
        render 'new'
    end
  end

  def show
    @user = User.find(params[:id])
  end

  def edit
    @user = User.find(params[:id])
  end

  def update
    @user = User.find(params[:id])
    if @user.update_attributes(user_params)
      flash[:success] = "Profile updated"
      redirect_to @user
    else
      render 'edit'
    end
  end

  def destroy
    User.find(params[:id]).destroy
    flash[:success] = "User deleted"
    redirect_to users_url
  end

private
  def user_params
    params.require(:user).permit(:email, :username, :password, :password_confirmation, :first_name, :last_name, :phone, :street_1, :street_2, :city, :state, :zip, :enabled, :admin)
  end

  def logged_in_user
  unless current_user.present?
      store_location
      flash[:danger] = "Please log in."
      redirect_to login_url
    end
  end

  def correct_user
    @user = User.find(params[:id])
    redirect_to(root_url) unless @user == current_user
  end

  def admin_user
    redirect_to(root_url) unless current_user.admin?
  end
end

在我的路线文件中，我有：

  resources :users

Answer 1

您可以使用括号表示法

link_to 'Edit profile', [:edit, current_user]

或named routes helpers，您可以通过调用rake routes

获得

link_to 'Edit profile', edit_user_path(current_user)

Answer 2

简单如下：

link_to 'Edit profile', [:edit, current_user]

路由到当前用户在视图中编辑
