我正在使用Rails 5.0.2運行counter_culture gem,v1.6.2(對於我當前不能升級到1.7)。我有一個ContactContactGroupGroup模型,就像這樣:ArgumentError:方法.group()必須包含參數

class Contact < ApplicationRecord 
    has_many :contact_groups 
    has_many :groups, through: :contact_groups 

    counter_culture [:contact_groups, :group], touch: true 
    counter_culture [:contact_groups, :group], 
     column_name: :confirmed_count, 
     column_names: { ["contacts.confirmed_at IS NOT NULL"] => 'confirmed_count' }, 
     touch: true 
end 

class ContactGroup < ApplicationRecord 
    belongs_to :contact 
    belongs_to :group 
    validates_uniqueness_of :contact_id, scope: :group_id 
end 

class Group < ApplicationRecord 
    has_many :contact_groups 
    has_many :contacts, through: :contact_groups 
end 

從我從閱讀的文檔明白,這種設置是正確的。如果我運行Contact.counter_culture_fix_counts,一切工作正常。如果我嘗試創建新聯繫人,如下所示,我收到以下錯誤消息。

c = Contact.new(attrs) 
[9] pry(main)> #<Contact id: nil, first_name: "Billy", last_name: "The Kid", email: "[email protected]" ...> 
c.valid?

c.save

我一直在努力弄清楚是什麼導致這一段時間,至今我唯一的工作原理是,有一個名稱衝突與我的模型Group和ActiveRecord的的.group()方法。我正在考慮將Group重命名爲其他內容,但這顯然是很多工作,所以我想首先查明我的理論是否正確,如果可能的話。思考?

問題是你已經使用了保存字group定義關係

belongs_to :group創建了的ActiveRecord的group方法http://guides.rubyonrails.org/active_record_querying.html#group衝突。

唯一的解決辦法是爲關係使用不同的名稱

這是我懷疑不幸的。我建立了一個新的分支,並將我的'Group'模型改爲'Team',這足以解決這個問題。謝謝! – ACIDSTEALTH
