我正在尝试开发 CodeFluent 方面来将实体的属性设置为全文索引。
我找到了这个链接,它的作用类似于我的目标。 http://blog.codefluententities.com/2012/11/27/using-the-sql-server-template-producer-to-generate-clustered-indexes/
但是,这使用 SQL 模板生成器。无论如何都可以将属性设置为完全在方面本身中的全文索引,因此我不必为所有项目安装/维护模板生成器和方面?
这是我到目前为止的 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,我正在尝试创建一个模板生产者,但是当我尝试将新的模板生产者添加到项目生产者列表时,它给了我编译错误,所以我可能做错了。
错误说:
Cannot convert type 'CodeFluent.Model.Producer' to 'CodeFluent.Producers.SqlServer.TemplateProducer'
这是我到目前为止的代码:
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;
}
