Deprecation warning: #apply_finder_options

问题

I get DEPRECATION WARNING: #apply_finder_options is deprecated. when trying this in my user.rb:

def User.search(search, page)
  paginate page: page,
           per_page: 10,
           conditions: ['name LIKE ?', "%#{search}%"],
           order: 'name'
end

Called through UsersController:

def index
  @users = User.search(params[:search], params[:page])
end

The pagination is done with the will_paginate gem.

What is triggering the warning and how can I fix it? Been trying some googling, but I find the docs not too comprehensive!

回答1:

I'm pretty sure you just need to pull the order and conditions options out of the paginate method and use Active Record for that instead:

def User.search(search, page)
  order('name').where('name LIKE ?', "%#{search}%").paginate(page: page, per_page: 10)
end
