AutoMapper.Extensions.OData

Creates LINQ expressions from ODataQueryOptions and executes the query.

NuGet Package Downloads

Usage

To use:

Configure object maps with explicit expansion.
Call the GetAsync or GetQueryAsync extension method from your OData controller. IMapper is an AutoMapper interface.

    public class CoreBuildingMappings : AutoMapper.Profile
    {
        public CoreBuildingMappings()
        {
            CreateMap<TBuilding, CoreBuilding>()
                .ForMember(d => d.Name, o => o.MapFrom(s => s.LongName))
                .ForMember(d => d.Tenant, o => o.MapFrom(s => s.Mandator))
                .ForAllMembers(o => o.ExplicitExpansion());

            CreateMap<TBuilder, OpsBuilder>()
                .ForAllMembers(o => o.ExplicitExpansion());
            CreateMap<TCity, OpsCity>()
                .ForAllMembers(o => o.ExplicitExpansion());
        }
    }

public static async Task<ICollection<TModel>> GetAsync<TModel, TData>(this IQueryable<TData> query, IMapper mapper, ODataQueryOptions<TModel> options, HandleNullPropagationOption handleNullPropagation = HandleNullPropagationOption.Default);
public static async Task<IQueryable<TModel>> GetQueryAsync<TModel, TData>(this IQueryable<TData> query, IMapper mapper, ODataQueryOptions<TModel> options, HandleNullPropagationOption handleNullPropagation = HandleNullPropagationOption.Default);

    public class CoreBuildingController : ODataController
    {

	private readonly IMapper _mapper;
        public CoreBuildingController(MyDbContext context, IMapper mapper)
        {
            Context = context;
            _mapper = mapper;
        }

        MyDbContext Context { get; set; }

        [HttpGet]
        public async Task<IActionResult> Get(ODataQueryOptions<CoreBuilding> options)
        {
            return Ok(await Context.BuildingSet.GetQueryAsync(_mapper, options));
        }
    }

Do not use the EnableQuery Attribute

Using EnableQuery with AutoMapper.Extensions.OData will result in some operations being applied more than once e.g. in the tests, if TMandator has a total of two records then without EnableQuery applied to the controller action, the OData query http://localhost:16324/opstenant?$skip=1&$top=1&$orderby=Name will return one record as expected. However with EnableQuery applied no records will be returned because the skip operation has been applied twice.

OData query examples:

	http://localhost:<port>/opstenant?$top=5&$expand=Buildings&$filter=Name eq 'One'&$orderby=Name desc
	http://localhost:<port>/opstenant?$top=5&$expand=Buildings&$filter=Name ne 'One'&$orderby=Name desc
	http://localhost:<port>/opstenant?$filter=Name eq 'One'
	http://localhost:<port>/opstenant?$top=5&$expand=Buildings&$orderby=Name desc
	http://localhost:<port>/opstenant?$orderby=Name desc
	http://localhost:<port>/opstenant?$orderby=Name desc&$count=true
	http://localhost:<port>/opstenant?$top=5&$filter=Name eq 'One'&$orderby=Name desc&$count=true
	http://localhost:<port>/opstenant?$top=5&$select=Name, Identity
	http://localhost:<port>/opstenant?$top=5&$expand=Buildings&$filter=Name ne 'One'&$orderby=Name desc
	http://localhost:<port>/opstenant?$top=5&$expand=Buildings($expand=Builder($expand=City))&$filter=Name ne 'One'&$orderby=Name desc
	http://localhost:<port>/opstenant?$top=5&$select=Buildings,Name&$expand=Buildings($select=Name,Builder;$expand=Builder($select=Name,City;$expand=City))&$filter=Name ne 'One'&$orderby=Name desc

	http://localhost:<port>/corebuilding?$top=5&$expand=Builder,Tenant&$filter=name ne 'One L1'&$orderby=Name desc
	http://localhost:<port>/corebuilding?$top=5&$expand=Builder($expand=City),Tenant&$filter=name ne 'One L2'&$orderby=Name desc
