MapInstantApis fails when key is not named id when using fluent interface [Bug]

[Wayne-Mather]

When using the fluent interface and not marking your keys with the [Key] annotation and those keys are not named "id" then the _IdLookup dictionary will not be filled with the keys for the entity.

This is due to MapApiExtensions having id hard coded into it. I wonder if it would be easy to add a configuration option to define how the property is matched? For example {ClassName}Id or {ClassName}_Id

I did a quick proof of concept by adding the following code in line 26 of MapApiExtensions:

var theType = typeof(C);
var keyName = $"{theType.Name}Id";
var idProp = theType.GetProperty("id", BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance) ??
           theType.GetProperty(keyName, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance) ??
       theType.GetProperties().FirstOrDefault(p => p.CustomAttributes.Any(a => a.AttributeType == typeof(KeyAttribute)));

Interesting idea.. let’s get a OR together and add it to the mix

Hi,

Can you confirm you have an off by 1 error in your message? O => P 😁

Doh… yea. iPhone autocorrect isn’t a fan of PR.

I am doing something like the following:

app.MapInstantAPIs<MyContext>(config =>
{
    config.IncludeTable(db => db.Contacts, ApiMethodsToGenerate.All, "addressBook");
    config.PrimaryKeyMappingConvention(new List<string>() { "{ClassName}Id", "{ClassName}_Id", });
});

But it means changing Configuration from private to internal so that MapApiExtensions has access to it. Is this going to be a problem?
