RubyonRails MySQL查询混乱

我想使我的代码更加简单和高效。我的代码是这样的（在模型中）

class Employee

我的控制器是这样的：

class EmployeesController < ApplicationController
  before_action :set_employee, only: [:show, :edit, :update, :destroy]
  # GET /employees
  # GET /employees.json
  helper_method :sort_column, :sort_direction

  def index
    @employees = Employee.all
    @employees = Employee.search(params[:employee_type])
    @employees = Employee.search(params[:search]).order(sort_column + " " + sort_direction).paginate(:per_page => 5, :page => params[:page])
  end 
end

class EmployeesController5，：page=>params[：page]）
结束
结束

我们可以从这样做开始

class EmployeesController < ApplicationController
  before_action :set_employee, only: [:show, :edit, :update, :destroy]
  # GET /employees
  # GET /employees.json
  helper_method :sort_column, :sort_direction

  def index
    if params[:employee_type].present?
      @employees = Employee.search(params[:employee_type])
    elsif params[:search].present?
      @employees = Employee.search(params[:search]).order(sort_column + " " + sort_direction).paginate(:per_page => 5, :page => params[:page])
    else
      @employees = Employee.all
    end
  end 
end

class EmployeesController5，：page=>params[：page]）
其他的
@employees=employeen.all
结束
结束
结束

现在你不会超越你的变量了

@xdazz谢谢你，伙计！看起来您在控制器@employees 3中超越了变量times@MZarogaza啊，我明白了。我只是新来的罗：D最终目标是什么？你想做什么？谢谢@Mzaragoza！我不知道我们可以把条件语句放在控制器中：D谢谢@我很乐意帮忙：）

class EmployeesController < ApplicationController
  before_action :set_employee, only: [:show, :edit, :update, :destroy]
  # GET /employees
  # GET /employees.json
  helper_method :sort_column, :sort_direction

  def index
    if params[:employee_type].present?
      @employees = Employee.search(params[:employee_type])
    elsif params[:search].present?
      @employees = Employee.search(params[:search]).order(sort_column + " " + sort_direction).paginate(:per_page => 5, :page => params[:page])
    else
      @employees = Employee.all
    end
  end 
end
