为Webservice客户端实现ActiveRecord

Question

I'm writing a webservice client with C#/MVC 4 that communicates with a REST-Webservice, using JSON.net on the client side. Everything is working fine so far, but I want to improve the architecture to make the handling more fluid.

I wrote a connector class and initialize it like this:

var conn = new MyConnector("admin", "admin", "http://localhost:9000");

Then I have a POCO class like this:

public class MyRecord
{
    [JsonProperty("record_id")]
    public string RecordId;
    ...

I'm saving changes by performing a PUT request to the Webservice. It looks like:

var updated = conn.UpdateRecord("MyRecordId", new  NameValueCollection{{"title","new_title"}});

What I want to do is to implement it more like ActiveRecord:

var myRecord = conn.GetRecord("myRecordId);
myRecord.title = "Foo";
myRecord.save();

That means that the MyRecord-class must be aware of the connection handler. That seems bad design to me, because MyRecord is basically a plain object. Another choice would be to pass the connection handler to the save-method, but that smells, too.

Any suggestions for improving it?

Answer 1

If you want a "plain record" you should not implement the activerecord pattern. That is a contradiction. It sounds to me like you are more interested in the repository pattern.

As references have a look at: Is Repository pattern as same as Active Record pattern?

or for a broader perspective of your options:
