Question

如何强制Orchard重新运行Migrations.Create方法来重新创建模块的数据？我见过的所有教程都使用Migrations.UpdateFrom方法让Orchard识别模块数据更改，但这意味着每次在开发过程中进行更改时我都必须创建一个新方法。这些方法对于实际版本更新有意义，但不适用于初始开发。

我尝试过禁用和重新启用模块，没有骰子。我还尝试卸载并重新安装模块，但运行uninstall命令会永久删除计算机中的模块，绕过回收站。

我对你的问题感到有点困惑，但我会尝试回答

迁移更新数据库和数据库中的数据。如果要对仪表板中显示的视图进行更改，则不应重新运行迁移。

但是，如果要更改模型和数据，则需要运行更多迁移或重置数据库并运行create migration。

当我重建我正在处理的模块时，它将运行任何未完成的迁移，而不必在我的本地版本上禁用/启用该模块，

也就是说，如果当前迁移版本为1并且存在UpdateFrom1方法，则在迁移中，这将在构建项目时运行。

您可以查看下表中的当前版本号Orchard_Framework_DataMigrationRecord

如果要强制重新运行迁移，可以重置数据库中表的值。或者，您可以备份数据库，并在运行整个迁移套件之前进行恢复。

在开发过程中，我使用简短的迁移，每次需要添加数据时创建一个方法，我会尽量保持这些小，以便在开发过程中轻松识别任何问题。

然后在完成模块之前，将迁移合并到2或3个逻辑代码块

以下是自定义类型的迁移

public int Create()
        {
            // Define the project type 
            ContentDefinitionManager.AlterTypeDefinition("Project", cfg => cfg
                .WithSetting("Stereotype", "Content")
                .CommomPart()
                .AutoroutePart("our-work")
                .BodyPart()
                .WithPart("TitlePart")
                .WithPart("PublishLaterPart")
                .WithPart("MenuPart", builder => builder
                    .WithSetting("MenuPart.OnMenu", "true")
                    .WithSetting("MenuPart.CurrentMenu", "Project Menu"))
                .WithPart("Project")
                .Creatable()
                .Draftable());

            return 1;

        }

        public int UpdateFrom1()
        {
            // Define project part - having a part with the same name will create fields in the project type
            ContentDefinitionManager.AlterPartDefinition("Project", builder => builder
               .MediaPickerField("MainImage")
               .MediaPickerField("MediumImage")
               .MediaPickerField("SmallImage")
               .MediaPickerField("Logo")
               .TextField("ShortDescription", Flavour.TextArea)
               .TextField("Features", Flavour.Markdown)
               .TextField("ClientTitle", Flavour.DefaultFlavour)
               .TextField("ClientName", Flavour.DefaultFlavour)
               .TextField("ClientQuote", Flavour.Textarea)
               .BooleanField("MainProjectOnHomePage", false)
               .Attachable());

            return 2;
        }

我添加了一些扩展方法，以减少冗长。

这里是

 public static class MigrationExtentionHelpers
    {
        // part definitions 

        public static ContentPartDefinitionBuilder MediaPickerField(this ContentPartDefinitionBuilder builder, 
                                                                    string name, bool required = true, string hint = "")
        {
            var displayName = SplitCamel(name);

            // default implementation of Media picker field - create overloads for more options
            return  builder.WithField(name, fieldBuilder => fieldBuilder
                        .OfType("MediaPickerField")
                        .WithDisplayName(displayName)
                        .WithSetting("MediaPickerFieldSettings.Required", required.ToString(CultureInfo.InvariantCulture))
                        .WithSetting("MediaPickerFieldSettings.AllowedExtensions", "jpg png gif")
                        .WithSetting("MediaPickerFieldSettings.Hint", hint));

        }

        public static ContentPartDefinitionBuilder TextField(this ContentPartDefinitionBuilder builder, 
                                                             string name, Flavour flavor, bool required = true, string hint = "")
        {
            var strFlavor = SplitCamel(flavor.ToString());

            // default implementation of Media picker field - create overloads for more options
            return builder.WithField(name, fieldBuilder => fieldBuilder
                        .OfType("TextField")
                        .WithSetting("TextFieldSettings.Required", required.ToString(CultureInfo.InvariantCulture))
                        .WithSetting("TextFieldSettings.Flavor", strFlavor)
                        .WithSetting("TextFieldSettings.Hint", hint));

        }

        public static ContentPartDefinitionBuilder BooleanField(this ContentPartDefinitionBuilder builder,
                                                                string name, bool defalut, string hint = "")
        {
            // default implementation of Media picker field - create overloads for more options
            return builder.WithField(name, fieldBuilder => fieldBuilder
                        .OfType("BooleanField")
                        .WithSetting("BooleanFieldSettings.Hint", hint)
                        .WithSetting("BooleanFieldSettings.DefaultValue", defalut.ToString(CultureInfo.InvariantCulture)));

        }

        // type definitions 

        public static ContentTypeDefinitionBuilder AutoroutePart(this ContentTypeDefinitionBuilder builder, string pathPrefix = "")
        {
            var pattern = string.Format("[{{Name:'{0}/Title', Pattern: '{0}/{{Content.Slug}}', Description: 'my-page'}}]", pathPrefix);

            return builder.WithPart("AutoroutePart", partBuilder => partBuilder
                        .WithSetting("AutorouteSettings.PatternDefinitions", pattern)); 
        }


        public static ContentTypeDefinitionBuilder BodyPart(this ContentTypeDefinitionBuilder builder, 
            Flavour defaultFlavour = Flavour.Markdown)
        {
            return builder.WithPart("BodyPart", partBuilder => partBuilder
                        .WithSetting("BodyTypePartSettings.Flavor", defaultFlavour.ToString()));            
        }

        public static ContentTypeDefinitionBuilder CommomPart(this ContentTypeDefinitionBuilder builder)
        {
            return builder.WithPart("CommonPart")
                        .WithSetting("OwnerEditorSettings.ShowOwnerEditor", false.ToString(CultureInfo.InvariantCulture).ToLower());

        }

        private static string SplitCamel(string enumString)
        {

            StringBuilder sb = new StringBuilder();

            char last = char.MinValue;
            foreach (char c in enumString)
            {
                if (char.IsLower(last) && char.IsUpper(c))
                {
                    sb.Append(' ');
                    sb.Append(c.ToString(CultureInfo.InvariantCulture).ToLower());
                }
                else
                {
                    sb.Append(c);
                }
                last = c;
            }
            return sb.ToString();

        }
    }

Answer 2

除非您从之前创建的备份中恢复数据库或直接调整数据，否则基本上无法运行两次迁移。至于我，这不是问题，因为在我的团队开发过程中，我们使用dbs的本地实例，并将所有迁移组合成初始迁移并部署到测试/暂存环境。
