Question

我试图在heroku中第一次部署我的应用程序，而且我遇到了一个奇怪的错误。当我尝试运行heroku rake db：migrate时，我看到了这个错误：

耙子流产了！ StandardError：发生错误，此错误以及稍后发生迁移已取消：

PG::UndefinedTable: ERROR:  relation "companies" does not exist
: CREATE TABLE "users" ("id" bigserial primary key, "admin" boolean DEFAULT 'f', "admin_c" boolean DEFAULT 'f', "color" character varying, "initial" character varying, "name" character varying, "surname" character varying, "pseudo" character varying, "step" integer, "company_id" bigint, "email" character varying DEFAULT '' NOT NULL, "encrypted_password" character varying DEFAULT '' NOT NULL, "reset_password_token" character varying, "reset_password_sent_at" timestamp, "remember_created_at" timestamp, "sign_in_count" integer DEFAULT 0 NOT NULL, "current_sign_in_at" timestamp, "last_sign_in_at" timestamp, "current_sign_in_ip" character varying, "last_sign_in_ip" character varying, "created_at" timestamp NOT NULL, "updated_at" timestamp NOT NULL, CONSTRAINT "fk_rails_7682a3bdfe"
FOREIGN KEY ("company_id")
  REFERENCES "companies" ("id")
)

我已经验证了我的迁移文件的一千倍用户＆amp;公司但似乎没有什么不好。所以我真的不知道该怎么做。我也尝试了所有的数据库重置等。就像在这个answer中一样。但没有什么对我有用。有没有人见过这个？我现在非常绝望。

PS：我也删除了pg和sql3的更改。

所以如果发现问题有用，我会给你我的代码

Company_model：

class Company < ApplicationRecord
  has_many :users, dependent: :destroy
  has_many :groups, dependent: :destroy
end

User_model：

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  belongs_to :company, optional: true

  has_many :users_group, dependent: :destroy
  has_many :groups, through: :users_group
  has_many :users_post, dependent: :destroy
  has_many :posts, through: :users_post
  has_many :tasks_users, dependent: :destroy
  has_many :tasks, through: :tasks_users

  has_many :requests, dependent: :destroy
  has_many :groupes_admin, dependent: :destroy
  has_many :posts, dependent: :destroy
  has_many :comments, dependent: :destroy
  has_many :tasks, dependent: :destroy

end

公司迁移：

class CreateCompanies < ActiveRecord::Migration[5.1]
  def change
    create_table :companies do |t|
      t.string :name
      t.string :ref

      t.timestamps
    end
  end
end

设计迁移：

class DeviseCreateUsers < ActiveRecord::Migration[5.1]
  def change
    create_table :users do |t|
      ## Database authenticatable
      t.boolean :admin, default: false
      t.boolean :admin_c, default: false
      t.string :color
      t.string :initial
      t.string :name
      t.string :surname
      t.string :pseudo
      t.integer :step

      t.references :company, index: true, foreign_key: true
      t.boolean :admin, default: false
      t.string :email,              null: false, default: ""
      t.string :encrypted_password, null: false, default: ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      t.integer  :sign_in_count, default: 0, null: false
      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.string   :current_sign_in_ip
      t.string   :last_sign_in_ip

      t.timestamps null: false
    end

    add_index :users, :email,                unique: true
    add_index :users, :reset_password_token, unique: true
  end
end

Answer 1

错误消息表明您尝试在companies表上创建对users的引用，但companies表尚未存在。请确保您的迁移顺序是companies之前创建的users。您也可以尝试一次性加载架构，而不是一次只使用heroku run rake db:schema:load迁移一个架构。

免责声明：rake db:schema:load将清除您的所有数据。它最适合用于设置新数据库。切勿针对已包含关键数据的生产数据库运行它。获得数据后，您需要进行增量迁移。

Answer 2

首先使用rake db:create创建数据库。
