@kakone kakone commented Jan 12, 2022

Adds a EnableDependencyInjection(Action<IServiceCollection> configureServices) method in ODataOptions to be able to add services (StringAsEnumResolver for example) in non-model scenario.

Fixes #422

Usage :

builder.Services
    .AddControllers()
    .AddOData(opt =>
    {
        opt.EnableQueryFeatures();
        opt.EnableDependencyInjection(services =>
        {
            services.AddSingleton<ODataUriResolver>(sp => new StringAsEnumResolver() { EnableCaseInsensitive = true });
        });
    });

  1. I don't like the method name
  2. Where will you use 'StringAsEnumResolver'?

  1. I don't like the method name

I agree, I don't like it too. I chose it because it was the method name I used with v7. A suggestion for another name ?

  1. Where will you use 'StringAsEnumResolver'?

I have a simple webservice with [EnableQuery] attribute and a non-edm model. The registered StringAsEnumResolver will be retrieved automatically in the ODataQueryOptions object and transmitted to the ODataQueryOptionParser.
Then, I can use an OData filter like State eq '2' instead of State eq 'Completed'.

I really like this change, but I think it is very important to add a test case

I left a couple of small comments, but I really like this change, thanks for adding the test case.

@xuzhg, since you are more familiar with this repo can you take a look to make sure it fits?

@kakone @corranrogue9 @xuzhg Could we get some traction on this? We've encountered this issue as well. In our case, we're using the AddODataQueryFilter extension method to enable OData queries on non-OData controllers. We end up with basically the same problem, i.e., there's no way to inject a StringAsEnumResolver so that our OData query filters are case-insensitive.

@kakone It looks ok to me but would you please take a look for my comments.
Besides, do you think we should make this available directly calling AddOData();

For example:

services.AddOData(); // this can inject the odata serivces into the global level service provider??
