我正在尝试开发一个CodeFluent方面,将实体的属性设置为全文索引。
我找到了这个链接,它做了一些类似于我的目标。http://blog.codefluententities.com/2012/11/27/using-the-sql-server-template-producer-to-generate-clustered-indexes/
但是,这使用了SQL模板生成器。是否存在将属性完全设置为方面本身的全文索引,因此我不必为所有项目安装/维护模板生成器和方面?
下面是我到目前为止拥有的C#方面代码:
public class FullTextIndexing : IProjectTemplate
{
public static readonly XmlDocument Descriptor;
public const string Namespace = "http://www.softfluent.com/aspects/samples/FullTextIndexing";
static FullTextIndexing()
{
Descriptor = new XmlDocument();
Descriptor.LoadXml(
@"<cf:project xmlns:cf='http://www.softfluent.com/codefluent/2005/1' defaultNamespace='FullTextIndexing'>
<cf:pattern name='Full Text Indexing' namespaceUri='" + Namespace + @"' preferredPrefix='fti' step='Tables'>
<cf:message class='_doc'>CodeFluent Full Text Indexing Aspect</cf:message>
<cf:descriptor name='fullTextIndexing'
typeName='boolean'
category='Full Text Indexing'
targets='Property'
defaultValue='false'
displayName='Full-Text Index'
description='Determines if property should be full text indexed.' />
</cf:pattern>
</cf:project>");
}
public Project Project { get; set; }
public XmlDocument Run(IDictionary context)
{
if (context == null || !context.Contains("Project"))
{
// we are probably called for meta data inspection, so we send back the descriptor xml
return Descriptor;
}
// the dictionary contains at least these two entries
Project = (Project)context["Project"];
// the dictionary contains at least these two entries
XmlElement element = (XmlElement)context["Element"];
Project project = (Project)context["Project"];
foreach (Entity entity in project.Entities)
{
Console.WriteLine(">>PROPERTY LOGGING FOR ENTITY "+entity.Name.ToUpper()+":<<");
foreach (Property property in entity.Properties)
{
Log(property);
if(MustFullTextIndex(property))
{
Console.WriteLine("CHANGING PROPERTY");
property.TypeName = "bool";
Log(property);
}
}
}
// we have no specific Xml to send back, but aspect description
return Descriptor;
}
private static bool MustFullTextIndex(Property property)
{
return property != null && property.IsPersistent && property.GetAttributeValue("fullTextIndexing", Namespace, false);
}
private static void Log(Property property)
{
Console.WriteLine(property.Trace());
}
}编辑一:
按照Meziantou的回答,我试图创建一个模板生成器,但是当我试图将新的模板生成器添加到项目生成器列表时,它会给我带来编译错误,所以我可能做错了。
错误说:
Cannot convert type 'CodeFluent.Model.Producer' to 'CodeFluent.Producers.SqlServer.TemplateProducer'下面是我到目前为止所掌握的代码:
public XmlDocument Run(IDictionary context)
{
if (context == null || !context.Contains("Project"))
{
// we are probably called for meta data inspection, so we send back the descriptor xml
return Descriptor;
}
// the dictionary contains at least these two entries
XmlElement element = (XmlElement)context["Element"];
Project project = (Project)context["Project"];
CodeFluent.Producers.SqlServer.TemplateProducer producer = new CodeFluent.Producers.SqlServer.TemplateProducer();
producer.AddNamespace("CodeFluent.Model");
producer.AddNamespace("CodeFluent.Model.Persistence");
producer.AddNamespace("CodeFluent.Producers.SqlServer");
Console.WriteLine(producer.Element);
//TODO: Need to figure out how to modify the actual template's contents
project.Producers.Add(producer); //Error happens here
// we have no specific Xml to send back, but aspect description
return Descriptor;

在示例代码中,使用方面只是因为它有一个描述符。CodeFluent实体使用描述符填充属性网格:
<cf:descriptor name="IsClusteredIndex" typeName="boolean" targets="Property" defaultValue="false" displayName="IsClusteredIndex" />

因此,当将此属性的值设置为true或false时,将从xml文件中添加或删除xml属性ns:IsClusteredIndex。
然后,SQL模板读取属性值以生成预期的SQL文件:
property.GetAttributeValue("sa:IsClusteredIndex", false)因此,这个方面不是强制性的,而是提供了一种图形界面友好的方式来添加/删除属性。如果不需要集成到图形界面中,则可以安全地删除该方面。
如果您的目标是集成到图形界面,您需要一个方面(XML或DLL)或生产者。如果您不想创建一个生成器,可以将模板嵌入到您的方面中。在构建过程中,您可以提取SQL模板并将SQL模板生成器添加到项目中,这样,所有内容都位于方面中。
