Ruby on rails Rails会阻止类似的控制器动作

我有两个独立的控制器，它们继承自

Admin:：UserBaseController

，显示可搜索、可排序的用户表，并使用相同的局部视图

• Admin:：UsersController

  -显示给定组织上下文中的用户

• Admin:：OrganizationsController

  -显示系统的所有用户

以下是Admin:：UsersController的索引方法：

  def index
    q = "%#{params[:search]}%"
    @users = User.where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])

    respond_to do |format|
      format.html # index.html.erb
      format.json { render :json => @users }
    end
  end

def edit
    @organization = Organization.find(params[:id])
    q = "%#{params[:search]}%"
    @users = @organization.users.where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])
end

q = "%#{params[:search]}%"
@users = @organization.users.search_identity( q ).user_order( sort_column, sort_direction).paginate(:page => params[:page])

以下是Admin:：OrganizationsController的编辑方法：

  def index
    q = "%#{params[:search]}%"
    @users = User.where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])

    respond_to do |format|
      format.html # index.html.erb
      format.json { render :json => @users }
    end
  end

def edit
    @organization = Organization.find(params[:id])
    q = "%#{params[:search]}%"
    @users = @organization.users.where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])
end

q = "%#{params[:search]}%"
@users = @organization.users.search_identity( q ).user_order( sort_column, sort_direction).paginate(:page => params[:page])

这两种方法在分配

@users

变量的方式上有很多相似之处。这是

用户

和

@组织的区别。用户

就是这样。我该如何擦干它？

移动

where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])

在用户界面中创建一个方法

例如：

def self.method_name(q,params)
  where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])
end

然后用这个方法来代替where，所以这里要强调的是范围。这将删除模型中单个位置的重复查询，并使您能够将作用域链接到类和关联上

class User < ActiveRecord::Base
  scope :search_identity, lambda { |identity| where("first_name like ? or last_name like ? or username like ?", identity, identity, identity) }
  scope :user_order, lambda { |column,direction| order("#{column} #{direction}") }
end

在Admin:：OrganizationsController中：

  def index
    q = "%#{params[:search]}%"
    @users = User.where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])

    respond_to do |format|
      format.html # index.html.erb
      format.json { render :json => @users }
    end
  end

def edit
    @organization = Organization.find(params[:id])
    q = "%#{params[:search]}%"
    @users = @organization.users.where("first_name like ? or last_name like ? or username like ?", q, q, q).order(sort_column + ' ' + sort_direction).paginate(:page => params[:page])
end

q = "%#{params[:search]}%"
@users = @organization.users.search_identity( q ).user_order( sort_column, sort_direction).paginate(:page => params[:page])

使每件事都简洁明了

望远镜正在改变我的生活。也找到其他地方使用它们。谢谢你的提示。
