我一直在寻找答案,但我处于停滞状态。一切都适用于我的本地开发环境,但一切都在生产(Heroku)上爆炸。使用相同的数据库(postgres)。即使我不相信我曾经发送过该方法,Heroku 也会炸毁 NoMethodError。

我有主要的 3 个模型(附加连接模型),一个嵌套表单具有 has_many :through 提交给所有三个模型,以及 Static_Pages#signup (充当新操作)和 Subscriptions_Controller#create 问题发生的地方。

楷模

class Location < ActiveRecord::Base
  attr_accessible :address_line_2, :city, :lat, :long, :name, :state, :street_address, :website, :zip, :phone_number, :user_id
  has_many :relationships
  has_many :users, :through => :relationships
end

class User < ActiveRecord::Base
  has_one :subscription
  has_one :plan, :through => :subscription
  has_many :relationships
  has_many :locations, :through => :relationships
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
  attr_accessible :first_name, :last_name, :email, :password, 
              :password_confirmation, :remember_me, :stripe_token,
              :phone_number,:location
end

class Subscription < ActiveRecord::Base
  attr_accessor :stripe_card_token
  attr_accessible :card_expiration, :card_type, :card_zip, 
                 :current_period_end, :current_period_start, :last_four, 
                 :next_bill_on, :plan_id, :status, :stripe_customer_token, 
                 :trial_end, :trial_start, :user_id
  belongs_to :plan
  belongs_to :user
end

class Relationship < ActiveRecord::Base
  belongs_to :user
  belongs_to :location
end

控制器

class StaticPagesController < ApplicationController
 def home
 end

 def signup
    @user           = User.new
    @plan           = Plan.find_by_identifier("basic_monthly")
    @location       = @user.locations.build
    @subscription   = Subscription.new
 end

 def thankyou
 end
end

class SubscriptionsController < ApplicationController
 def create
   @subscription        = Subscription.new params[:subscription]
   @user                = User.create! params[:user]
   @subscription.user      = @user
   @user.locations << Location.create!(params[:location])
   @plan = Plan.find params[:subscription][:plan_id]
    if @subscription.save
      redirect_to thankyou_path
    else
      render template: 'static_pages#signup'
    end
  end
end

注册表单

<%= form_for @user, :url => subscriptions_path(@user) do |user_form| %>
  First name            : <%= user_form.text_field :first_name %><br />
  Last name             : <%= user_form.text_field :last_name %><br />
  Email                 : <%= user_form.email_field :email %><br />
  Phone Number          : <%= user_form.phone_field :phone_number %><br />
  Password              : <%= user_form.password_field :password %><br />
  Password Confirmation : <%= user_form.password_field :password_confirmation %><br />

  <%= fields_for @location do |location_fields| %>
    Business Name       : <%= location_fields.text_field :name %><br />
    Street Address      : <%= location_fields.text_field :street_address %><br />
    Address Line 2      : <%= location_fields.text_field :address_line_2 %><br />
    City                : <%= location_fields.text_field :city %><br />
    State               : <%= location_fields.text_field :state %><br />
    Zip                 : <%= location_fields.text_field :zip %><br />
    Website             : <%= location_fields.url_field :website %><br /><br />
  <% end %>

  <%= fields_for @subscription do |subscription_field| %>
    <%= subscription_field.hidden_field :plan_id, value: @plan.id  %>
  <% end %>

  <%= user_form.submit "Sign up", :class => 'btn primary large' %>
<% end %>

最后... Heroku 日志抛出的错误(同样,这在我的本地机器上运行良好) Heroku 错误 - 已更新

如果需要,我可以上传架构,但本质上如下: 架构的迷你版

subscriptions
 user_id
 plan_id
 ...
relationships
 user_id
 location_id
locations (all :null => false)
 name
 street_address
 city
 state
 zip
 ...

heroku run rake db:migrate 也不起作用 它会引发“数据库配置未指定适配器”异常,但 Heroku 会覆盖 database.yml 文件,为什么会发生这种情况?

我犯了一个愚蠢的错误(在 Ruby 和一般编程中仍然是新手)。我有一个以前的模型old_user.rb,它与其他错误class User < ActiveRecord::Base发生冲突user.rb并产生了其他错误。出于某种原因,我猜我的开发机器上的加载顺序与 Heroku 的加载顺序不同,以及为什么我从未意识到这一点。
