如何解決在rails 4中整個佈局渲染問題

Question

我在渲染整個佈局時遇到問題。在Controller新行動中，如果工資單已經創建，意味着它將顯示消息，如已創建的工資單。否則它不會顯示任何東西。但它呈現整個佈局。爲老師創建第一個工資單時會發生這種情況。

控制器

def new 
     @teacher_payslip = TeacherPayslip.new 
     @teacher = Teacher.find(params[:teacher_id]) 
    if params[:date] and TeacherPayslip.find_by_teacher_id(params[:teacher_id]).present? 
     @old_salary_date = TeacherPayslip.where(:teacher_id => params[:teacher_id]) 
     @new_salary_date = params[:date].to_date 
     @b = @new_salary_date.strftime("%b%Y") 
     @payslip = Array.new 
     @old_salary_date.each do |i| 
     a = i.salary_date.strftime("%b%Y") 
     @payslip << a 
     end 
     if @payslip.include?(@b) 
     @payslip_detail = TeacherPayslip.where("MONTH(salary_date) = ? and YEAR(salary_date) = ? and teacher_id = ? ",@new_salary_date.month, @new_salary_date.year,params[:teacher_id]).first 
     flash[:err] = "Payslip already Created" 
     respond_to do |format|

雖然我不明白爲什麼你.js.erb文件將呈現佈局，您應該嘗試使用:layout => false來電，如下所示：

def new 
      @teacher_payslip = TeacherPayslip.new 
      @teacher = Teacher.find(params[:teacher_id]) 
     if params[:date] and TeacherPayslip.find_by_teacher_id(params[:teacher_id]).present? 
      @old_salary_date = TeacherPayslip.where(:teacher_id => params[:teacher_id]) 
      @new_salary_date = params[:date].to_date 
      @b = @new_salary_date.strftime("%b%Y") 
      @payslip = Array.new 
      @old_salary_date.each do |i| 
      a = i.salary_date.strftime("%b%Y") 
      @payslip << a 
      end 
      if @payslip.include?(@b) 
      @payslip_detail = TeacherPayslip.where("MONTH(salary_date) = ? and YEAR(salary_date) = ? and teacher_id = ? ",@new_salary_date.month, @new_salary_date.year,params[:teacher_id]).first 
      flash[:err] = "Payslip already Created" 
      respond_to do |format| 
      format.js { render :layout => false } 
      end 
      else 
      render nothing: true 
      end 
     end 
     end 

你想要注意的是thin controller, fat model的原理。控制器是完全可以很容易地放入模型

我建議尋找到class functions條件邏輯的，這樣你就可以調用這些函數，而不是依靠碼這麼多的線路中的控制器動作的
