Answer 1

错误是因为您的create.html.erb文件夹中没有名为views/admin/citizens的文件。

在Rails中，如果您没有告诉它在Controller方法的末尾重定向或呈现特定模板，它会推断出要渲染的模板，因此：

class UsersController < ApplicationController
  def create
    @user = User.create(name: params[:name])
  end
end

如果在此处运行create方法，则将创建一个用户，然后Rails将尝试呈现模板views/users/create.html.erb。通常情况下，您将没有具有该名称的模板 - 您可能会执行以下操作：

class UsersController < ApplicationController
  def create
    @user = User.create(name: params[:name])
    redirect_to user_path(@user)
  end
end

或者：

class UsersController < ApplicationController
  def create
    @user = User.create(name: params[:name])
    render :awesome_template
end

我认为您需要在未保存用户时添加其他部分来处理

def create
  @user = User.new(new_params) 
  if @user.save 
    redirect_to admin_home_user_panel_path
  else
    #do render or redirect_to
  end 
end

创建新用户时出现“丢失模板”错误
