Question

我正在使用Nginx，Capistrano，Rails运行服务器

我在本地计算机上进行了一些db：migrations，然后想要将这些更改推送到我的服务器。但是，我无法弄清楚如何在服务器上迁移我的数据库。我该怎么做？

我试过

1）

cap production deploy
cap production deploy:migrate

2）

[On server - in current]
rake db:migrate

但这些似乎都不起作用。如何进行此迁移？

Capistrano档案

lock '3.4.0'
 require 'capistrano/sidekiq'
 set :whenever_command, "bundle exec whenever"
 require "whenever/capistrano"
set :application, 'myApp'
set :repo_url, 'git...'
set :keep_releases, 5
set :scm, :git
set :repository, "git..."
set :scm_passphrase, "..."
set :user, "..."
set :use_sudo, false
set :deploy_to, "/.../.../apps/appName"
namespace :deploy do
  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
    end
  end
end

Answer 1

1）如果您使用的是capistrano-rails，则应设置

set :migration_role, 'migrator'            # Defaults to 'db'

2）在服务器上，您正在开发环境中进行迁移，请尝试

RAILS_ENV=production bundle exec rails db:migrate

要使用capistrano运行迁移，在保留在HorzScrollBox内的object GridViewForm: TGridViewForm Left = 0 Top = 0 Caption = 'Grid Form' ClientHeight = 946 ClientWidth = 2600 StyleBook = StyleBook2 FormFactor.Width = 1280 FormFactor.Height = 1024 FormFactor.Devices = [dkDesktop] FormFamily = 'Main' FullScreen = True OnMouseUp = FormMouseUp Touch.InteractiveGestures = [igPan] OnGesture = FormGesture DesignerMobile = False DesignerWidth = 0 DesignerHeight = 0 DesignerDeviceName = '' DesignerOrientation = 0 DesignerOSVersion = '' object MainLayout: TLayout Align = alContents Height = 921.000000000000000000 Margins.Top = 25.000000000000000000 Width = 2600.000000000000000000 object HorzScrollBox1: THorzScrollBox Align = alClient Height = 921.000000000000000000 TabOrder = 0 Width = 2600.000000000000000000 object GroupLayout1: TLayout Align = alLeft Anchors = [akLeft, akTop] Height = 905.000000000000000000 Margins.Left = 110.000000000000000000 Position.X = 110.000000000000000000 Width = 540.000000000000000000 object ListBox4: TListBox Align = alClient Height = 905.000000000000000000 StyleLookup = 'collectionlistbox' TabOrder = 0 Width = 540.000000000000000000 DefaultItemStyles.ItemStyle = '' DefaultItemStyles.GroupHeaderStyle = '' DefaultItemStyles.GroupFooterStyle = '' end end object GroupLayout2: TLayout Align = alLeft Anchors = [akLeft, akTop] Height = 905.000000000000000000 Margins.Left = 40.000000000000000000 Position.X = 690.000000000000000000 Width = 1225.000000000000000000 end object Layout1: TLayout Align = alLeft Anchors = [akLeft, akTop] Height = 905.000000000000000000 Margins.Left = 40.000000000000000000 Margins.Right = 100.000000000000000000 Position.X = 1955.000000000000000000 Width = 660.000000000000000000 object Label1: TLabel Align = alTop AutoSize = True Height = 40.000000000000000000 Margins.Left = 10.000000000000000000 Margins.Bottom = 5.000000000000000000 Position.X = 10.000000000000000000 StyleLookup = 'pagesubheaderlabel' Text = 'Group Title: 4' Width = 165.000000000000000000 WordWrap = False end object ListBox1: TListBox Align = alClient Height = 855.000000000000000000 StyleLookup = 'collectionlistbox' TabOrder = 1 Width = 660.000000000000000000 DefaultItemStyles.ItemStyle = '' DefaultItemStyles.GroupHeaderStyle = '' DefaultItemStyles.GroupFooterStyle = '' end end end end object StyleBook2: TStyleBook Left = 632 Top = 544 ResourcesBin = {...} end object PrototypeBindSource1: TPrototypeBindSource AutoActivate = True AutoPost = False FieldDefs = < item Name = 'ContactBitmapL1' FieldType = ftBitmap Generator = 'ContactBitmapsL' ReadOnly = False end item Name = 'ContactName1' Generator = 'ContactNames' ReadOnly = False end item Name = 'IntField1' FieldType = ftInteger Generator = 'Integers' ReadOnly = False end> ScopeMappings = <> Left = 1288 Top = 456 end object BindingsList1: TBindingsList Methods = <> OutputConverters = <> Left = 20 Top = 5 object LinkFillControlToField1: TLinkFillControlToField Category = 'Quick Bindings' Control = ListBox4 Track = True FillDataSource = PrototypeBindSource1 FillDisplayFieldName = 'ContactName1' AutoFill = True BufferCount = -1 AutoBufferCount = False ListItemStyle = 'MetropolisUI' FillExpressions = < item SourceMemberName = 'ContactBitmapL1' ControlMemberName = 'Icon' end item SourceMemberName = 'IntField1' ControlMemberName = 'SubTitle' end> FillHeaderExpressions = <> FillBreakGroups = <> end object LinkFillControlToField2: TLinkFillControlToField Category = 'Quick Bindings' Control = ListBox1 Track = True FillDataSource = PrototypeBindSource2 FillDisplayFieldName = 'ContactName1' AutoFill = True BufferCount = -1 AutoBufferCount = False ListItemStyle = 'MetropolisUI' FillExpressions = < item SourceMemberName = 'FloatField1' ControlMemberName = 'SubTitle' end item SourceMemberName = 'ContactBitmap1' ControlMemberName = 'Icon' end> FillHeaderExpressions = <> FillBreakGroups = <> end end object PrototypeBindSource2: TPrototypeBindSource AutoActivate = True AutoPost = False FieldDefs = < item Name = 'ContactBitmap1' FieldType = ftBitmap Generator = 'ContactBitmaps' ReadOnly = False end item Name = 'ContactName1' Generator = 'ContactNames' ReadOnly = False end item Name = 'FloatField1' FieldType = ftSingle Generator = 'Floats' ReadOnly = False end> ScopeMappings = <> Left = 1232 Top = 448 end end文件上添加“db”角色 e.g。

production.rb

如果/config/deploy和roles: %w{web app db}迁移之间存在差异，也可以使用capistrano迁移任务。您可以做的是从current_path内部删除迁移，然后部署然后迁移。
