「未初始化的恆定用戶」當設置狂歡和煉油廠時

Question

我一直在試圖設置狂熱和煉油廠以下目的： 使用相同的認證系統爲。

根據一個github上的項目和後續的拉進大禮包主分支......這應該順利（在第一個答案的評論可用鏈路）

我給了一個艱難的嘗試，但我無法擺脫的「未初始化的常量用戶「錯誤。我將嘗試描述能夠複製錯誤的所有必要步驟。

Firstofall，該環境在：

gem install rails 
rails new spreefinery 
cd spreefinery 

# resolve a dependency on which bundler fails 
sed "s/'jquery-rails'/'jquery-rails', '~>2.0.0'/g" -i Gemfile 

echo "# adding custom gems for both spree and refinery 
gem 'spree', :git => 'git://github.com/spree/spree.git', :branch => '1-2-stable' 
gem 'spree_usa_epay' 
gem 'spree_skrill' 
gem 'refinerycms', :git => 'git://github.com/refinery/refinerycms.git', :branch => '2-0-stable'" >> Gemfile 

bundle install 

其次，作爲與補丁在guide

rails generate refinery:cms --fresh-installation 

指示用於分頁

echo "#Refinery uses the will_paginate gem for pagination, 
# while Spree uses Kaminari.... This fix makes both happy 

if defined?(WillPaginate) 
    module WillPaginate 
    module ActiveRecord 
     module RelationMethods 
     alias_method :per, :per_page 
     alias_method :num_pages, :total_pages 
     end 
    end 
    end 
end" > config/initializers/spreefinery.rb 

最終安裝煉油廠，安裝禮包（無認證）

個

bundle exec spree install --git=git://github.com/spree/spree.git --branch=1-2-stable 

# use default config except for authentification : 
    Would you like to install the default gateways? (yes/no) [yes] 
    Would you like to install the default authentication system? (yes/no) [yes] no 
    What is the name of the class representing users within your application? [User] 
    Would you like to run the migrations? (yes/no) [yes] 
    Would you like to load the seed data? (yes/no) [yes] 
    Would you like to load the sample data? (yes/no) [yes] 

這最後一個命令運行爲：

gemfile spree 
gemfile spree_usa_epay 
gemfile spree_skrill 
    run bundle install from "." 
    create config/initializers/spree.rb 
    create config/spree.yml 
    remove public/index.html 
    append public/robots.txt

    create app/assets/stylesheets/store/all.css 
    create app/assets/stylesheets/admin/all.css 
    create app/overrides 
    append config/environment.rb 
    append db/seeds.rb 
copying migrations 
creating database

Enjoy! 

你可以看到在DB的錯誤：種子一步。

同樣的錯誤再次出現在rails server或rake db上：migrate。這裏是完整的回溯：

我需要一些幫助在這一點上。我發現了一些關於這個錯誤的帖子，說明的模型用戶可能不存在......但煉油廠明確宣佈User class ......所以我有點困惑。

感謝您的幫助！ Manu

Answer 1

終於得到它，它看起來像那麼容易.... mmmfff

所以我不得不指定「煉油廠::用戶」（不是簡單的「用戶」），以對用戶的問題。

Would you like to install the default gateways? (yes/no) [yes] 
Would you like to install the default authentication system? (yes/no) [yes] no 
What is the name of the class representing users ...? [User] **Refinery::User** 
Would you like to run the migrations? (yes/no) [yes] 
Would you like to load the seed data? (yes/no) [yes] 
Would you like to load the sample data? (yes/no) [yes] 

所以邏輯:)

Answer 2

您正在嘗試安裝spree並運行標準遷移，但是我可以從您的條目中看到，您已明確聲明不安裝默認授權系統（它與精煉廠基於devise一樣）。因此，在用戶模型上運行的一些遷移失敗。

    > [User] Would you like to run the migrations? (yes/no) [yes] 
    > Would you like to load the seed data? (yes/no) [yes] Would you like 
    > to load the sample data? (yes/no) [yes] 

如果試圖重新安裝，但這次說是「你想安裝默認的認證系統？」那麼它應該工作。本週我一直在研究類似的系統，並且工作正常。你將在你的數據庫中得到兩個名字空間的用戶數據庫表，但是如果你想讓這兩個系統共享一個單獨的認證系統，那麼我認爲你需要做一些工作，而標準的安裝程序不會適用。
