Veri kümemi nasıl yönlendiririm?Veri kümemi oda tabanını kullanarak doğru şekilde nasıl filtreleyebilirim?
Bir OData bitiş noktası teşhir ve URL'ye çalışıyorum:?
http://localhost:5001/mystuf/api/v2/AccountSet $ filtresi = accountid% 20eq% 20guid% 2703a0a47b-e3a2-e311-9402-00155d104c22% 27
benim OData son nokta bu guid üzerinde veri kümesini filtrelemek çalıştığında, ben alıyorum:

An entity member is invoking an invalid property or method.", "type": "System.NotSupportedException" { "odata.error": { "code": "", "message": { "lang": "en-US", "value": "An error has occurred." }, "innererror": { "message": "Invalid 'where' condition.

CSDL dosya tuvaletten başlangıç Böyle ks şey:
public IHttpActionResult Get(ODataQueryOptions<Account> options)
{
var retval = options.ApplyTo(_accountService.GetAccountSet());
return Ok(retval);
}
ve yukarıdaki Get yöntemi süzgeci uygular:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Schema Namespace="Xrm" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm">
<EntityType Name="Account">
<Key>
<PropertyRef Name="AccountId" />
</Key>
<Property Name="TerritoryCode" Type="Microsoft.Crm.Sdk.Data.Services.OptionSetValue" Nullable="false" />
<Property Name="LastUsedInCampaign" Type="Edm.DateTime" Nullable="true" />
...
kontrolör tetiklenir oluyor ise eğer doğru nasıl filtre
public IQueryable<Account> GetAccountSet()
{
return _xrmServiceContext.AccountSet;
}
veri kümemi rehbere göre mi?
yerine bu döndüğünüzde lütfen unutmayın: Sonra veri istemciye doğru döndürülür
return _xrmServiceContext.AccountSet.Take(2);
(seri/seri kaldırma düzgün çalışır); Bununla birlikte, filtre hiç uygulanmamaktadır.
Kişisel OData sorgu yanlıştır görmek için her iki url test edebilirsiniz. Bir filtre için sorgu yapısı şöyledir: $ filter = property eq 'value', $ filter = property eq property 'value'. $ Filter = AccountId eq 'guid value' öğesini deneyin. –
"URI'de belirtilen sorgu geçerli değil. Uyumsuz türlere sahip bir ikili işleci algılandı." Edm.Guid "ve" Edm.String "işlenen türleri için" Equal "operatörü türü bulundu." }, –
/api/v2/AccountSet? $ Filtre = AccountId eq '03a0a47b-e3a2-e311-9402-00155d104c22' –
