在生产服务器上使用 will_paginate 时出现此错误:
I, [2013-10-24T20:17:40.386696 #18564] INFO -- : Started GET "/meals" for 190.273.432.55 at 2013-10-24 20:17:40 +0000

NoMethodError (undefined method `paginate' for #<ActiveRecord::Relation::ActiveRecord_Relation_Meal:0x00000005080598>):
app/controllers/meals_controller.rb:5:in `index'
这就是我在控制器中使用它的方式:
@meals = current_user.meals.order("created_at DESC").paginate(:page => params[:page], :per_page => 6)
我的看法是:
<%= will_paginate @meals %>
我已经尝试过“生产中的 will_paginate 错误 NoMethodError (undefined method `page' for []:ActiveRecord::Relation) ”中建议的解决方案以及GitHub 上的相同问题,但它没有用。我还检查了服务器和本地是否具有相同的 Ruby 安装。
这在开发中有效。服务器设置为:Ubuntu 12.10、Nginx、Unicorn、Capistrano、Ruby 2.0.0p247、Rails 4.0.0。有什么建议么?
我的宝石文件是:

部署.rb 是:

require "rvm/capistrano"

set :repository, "git@github.com:xxxx/#{application}.git"
set :branch, "master"
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
after "deploy", "deploy:cleanup" # keep only the last 5 releases
namespace :deploy do
%w[start stop restart].each do |command|
desc "#{command} unicorn server"
task command, roles: :app, except: {no_release: true} do
run "/etc/init.d/unicorn_#{application} #{command}"
end
end
task :setup_config, roles: :app do
sudo "ln -nfs #{current_path}/config/nginx.conf /etc/nginx/sites-enabled/#{application}"
sudo "ln -nfs #{current_path}/config/unicorn_init.sh /etc/init.d/unicorn_#{application}"
run "mkdir -p #{shared_path}/config"
put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml"
puts "Now edit the config files in #{shared_path}."
end
after "deploy:setup", "deploy:setup_config"
task :symlink_config, roles: :app do
run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end
after "deploy:finalize_update", "deploy:symlink_config"
desc "Make sure local git is in sync with remote."
task :check_revision, roles: :web do
unless `git rev-parse HEAD` == `git rev-parse origin/master`
puts "WARNING: HEAD is not the same as origin/master"
puts "Run `git push` to sync changes."
exit
end
end
before "deploy", "deploy:check_revision"
end
更新:我重新安装了服务器,现在它可以工作了。不知道为什么...
