我有一个非常奇怪的错误,当我提交表单以创建新管理员时,我收到此错误:
NoMethodError in AdminsController#create
undefined method `admin?' for #<Admin:0x6c7f098>
排队:
if @admin.save
这个错误是如何产生的?我主要使用脚手架代码,我只删除了控制器的视图!这是我的控制器:感谢大家的帮助!
class AdminsController < ApplicationController
before_action :set_admin, only: [ :edit, :update, :destroy]
# GET /admins/new
def new
@admin = Admin.new
end
# GET /admins/1/edit
def edit
end
# POST /admins
# POST /admins.json
def create
@admin = Admin.new(admin_params)
respond_to do |format|
if @admin.save
format.html { redirect_to adminpage_index_path, notice: 'Admin was successfully created.' }
else
redirect_to adminpage_index_path
end
end
end
# PATCH/PUT /admins/1
# PATCH/PUT /admins/1.json
def update
respond_to do |format|
if @admin.update(admin_params)
format.html { redirect_to adminpage_index_path , notice: 'Admin was successfully updated.' }
format.json { head :no_content }
else
redirect_to adminpage_index_path
end
end
end
# DELETE /admins/1
# DELETE /admins/1.json
def destroy
@admin.destroy
respond_to do |format|
format.html { redirect_to adminpage_index_path }
end
end
