We should retire the read-only version of TripPin as it doesn't add any value beyond the read/write version of TripPin. Also, while we will presumably implement over a stack, I am not convinced that services.odata.org is the right place to host multiple variants of TripPin so we should build the sample service on the stack that allows us to implement the most important/requested features and not worry about hosting the same service multiple times. This means we only need one TripPin service, not a read TripPin service over ODL, a read/write TripPin service over ODL, and a read/write TripPin service over Web API OData.

So:

1. Retire the read-only service, and
2. Choose between ODL and Web API OData and only host one version of TripPin

Note: the stack supporting the reference service can change over time, but there's just not a compelling case to support the same reference service over multiple stacks.

Sorry ... The filter has to be implemented (as mentioned in the code)

I'm having trouble using the example approach provided for composite primary keys.

To be as brief as possible, the problem is apparently in this line of code.

RouteValues.ContainsKey (ODataRouteConstants.Key)

The above line works correctly while the url is for a resource that does not have a compound key, because in this Array / Collection there is an entry like "key", but when the resource to be searched has a composite key, The "key" is separated into two or more entries in the array, which of course are not called "key", instead they are called "key {FiledKeyName}".

Am I doing something wrong? Or was there any update that the Example is not up to date?

If further details are needed, please let me know.

I have a service in OdataV4 and *_$count *_property is not working as described in the specifications, returns this mesage -. "The query specified in the URI is not valid 'with' expected at position 46 in 'groupby ((Medico / Pk_distrito) , aggregate ($count the NumReceitas)) '. "

The original issue is here: OData/odataorg.github.io#66

Quoting the author:

And thus can not be used from a web browser for testing JS, for instance.

Workaround

None that I know. I'd tipically just uso JSONP, but $metadata can not be requested by JSONP.

The reporter was able to reproduce this problem against V2, V3 and V4 Northwind services. He hasn't tested TripPin services yet, but they may have the same problem.

[From Vlad Filyakov]
Looking at the data represented by the Trip objects, I wonder if StartsAt and EndsAt properties should have a new Date type instead of DateTimeOffset (all the time zone values have zero time)? It would also help to showcase new features of OData v4. Right now the TripPin service has an example of Duration, but nothing for Date and TimeOfDay.

NOTES:
Date, TimeOfDay not supported in Web API OData yet but now supported in ODL
Modify the data behind ODL to add time zone values to StartsAt and EndsAt

Move the code of v4, v3, v2 sample services to GitHub.
http://www.odata.org/odata-services/

Steps to duplicate:

1. Download the AdventureWorksLTSample
2. Build. Build works.
3. Remove all previous NuGet packages
   get-package | uninstall-package -force
4. Install updated NuGet packages
   install-package Microsoft.Restier
5. Build. Build fails.

It looks like the issues are in the WebApiConfig.cs as some objects no longer exist.

I cannot get the IEEE754Compatible=true header or query string parameter to work in any code. It works in your live sample but not in this version available. What do you have configured for that? Is this the latest source?

https://github.com/OData/ODataSamples/tree/master/Scenarios/TripPin
Either the ODataLib one, or the Web API one to support capability vocabulary done in ODataLib 6.13 and OData Web API 5.7.
Refer an existing sample: https://github.com/OData/ODataSamples/tree/master/WebApi/v4/ODataCapabilitiesVocabularySample

There is no EntitySet corresponding to the EntityType 'Trip'. So I believe in order to add a trip for a person, we need to send to POST request to the Trips's url through person. e.g.

POST /People('russellwhyte')/Trips

This is how we add a record for containment navigation property.
According to OData v4 spec (http://docs.oasis-open.org/odata/odata/v4.0/errata03/os/complete/part3-csdl/odata-v4.0-errata03-os-part3-csdl-complete.html#_Toc453752542), ContainsTarget should be true for a containment navigation property. ContainsTarget also isn't set for Trips navigation property.

Is it a containment navigation property ?

You can delete unnecessary PropertyValue elements like

<PropertyValue Property="NonInsertableNavigationProperties">
                                  <Collection/>
</PropertyValue>

in several places. We wrote in the specifications “For collection-valued properties the absence of an edm:PropertyValue child element is equivalent to specifying a child element with an empty collection as its value.”, see http://docs.oasis-open.org/odata/odata/v4.0/errata01/os/complete/part3-csdl/odata-v4.0-errata01-os-part3-csdl-complete.html#_Toc395268278

Hi

This works fine:

http://services.odata.org/V4/TripPinService/People('russellwhyte')/Trips(0)/PlanItems?$filter=contains(ConfirmationCode,%27JH%27)

and this one generates an exception:

http://services.odata.org/V4/TripPinService/People('russellwhyte')/Trips(1003)/PlanItems?$filter=contains(ConfirmationCode,%27JH%27)

{

The only difference is that filter is applied to Trips(0) in the first case and to Trips(1003) in the second.

HI,

I Have an Odata V4 Controller setup and i am using TransientAction to express if i an action can be eecuted in the current state so i dont have to have duplicated code in client and server.

This works fine with angular and js in general.

i can do:

var actionLink= item['#Action'];;
if (!actionLink) {
return;
}
$http.post(actionLink.target, {});
....

I didnt find a way to do that with odata client as the proxy generator does not map functions in the objects.

i found OperationDescriptions on the EntityDescription but they are always present.

can anyone help me with this issue?

btw. its a little ugly to only be able to call actions with an extension on DataServiceQuerySingle.

why isnt the selflink and all the other selfdocumentation ( editlink etc. )only available via entityDescriptor and not part of each object?

Update ODataLib and OData Web API of samples to a latest version.

Hi
I have a requirement of retrieving data from database dynamically based on API methods. For which i got the sample code from stack overflow for the same code mentioned in Github.

https://stackoverflow.com/questions/29981931/dynamic-odata-service-in-c-sharp-from-runtime-data-layer

But it doesn't show or suggest how to apply the Filter options.Sample code mentioned below

public EdmEntityObjectCollection Get()
{
// get Edm type from request
ODataPath path = Request.ODataProperties().Path; // ODataProperties() needs using System.Web.OData.Extensions
IEdmType edmType = path.EdmType;

    IEdmCollectionType collectionType = (IEdmCollectionType)edmType;
    IEdmEntityType entityType = (IEdmEntityType)collectionType.ElementType.Definition;
    IEdmModel model = Request.ODataProperties().Model;

    ODataQueryContext queryContext = new ODataQueryContext(model, entityType, path);
    ODataQueryOptions queryOptions = new ODataQueryOptions(queryContext, Request);

    // TODO: apply the query option on the IQueryable here.
    // read all rows from table (could be optimized using query context)

    var table = (DatabaseTable)ControllerContext.ControllerDescriptor.Properties["table"];
    var cnx = (string)ControllerContext.ControllerDescriptor.Properties["connectionString"];
    var data = ReadData(entityType, table, cnx);

    var a = queryOptions.ApplyTo(data.AsQueryable());


    return new EdmEntityObjectCollection(new EdmCollectionTypeReference(collectionType), data);
}

Any help on this will be much appreciated

        }
    }
}

Is there any working multilevel expand example out there, or am I just getting $expand wrong?

According to OData documentation "The $count system query option ignores any $top, $skip, or $expand query options", but in TripPin those query options are taken into account when returning "@odata.count". E.g.

http://services.odata.org/V4/TripPinService/People?$top=2&$count=true => returns "@odata.count": 2
http://services.odata.org/V4/TripPinService/People?$skip=2&$count=true => returns "@odata.count":22 (in the "skip" example it is returning the total elements in the list minus the skip value ~ 24 - 2)

I am trying one of the samples and getting following error
Severity Code Description Project File Line Suppression State
Error CS1061 'HttpConfiguration' does not contain a definition for 'Filter' and no extension method 'Filter' accepting a first argument of type 'HttpConfiguration' could be found (are you missing a using directive or an assembly reference?)

Had a key as segment sample, need add it to the ODataSamples/WebApi

Related page: http://odata.github.io/WebApi/version-constraint-relax-flag/

The corrected NavigationPropertyBindings are (if TripPin is defined as an alias fro the schema namespace):

         <NavigationPropertyBinding Path="Friends" Target="People"/>
          <NavigationPropertyBinding Path="Trips/PlanItems/TripPin.Flight/Airline" Target="Airlines"/>
          <NavigationPropertyBinding Path="Trips/PlanItems/TripPin.Flight/From" Target="Airports"/>
          <NavigationPropertyBinding Path="Trips/PlanItems/TripPin.Flight/To" Target="Airports"/>
          <NavigationPropertyBinding Path="Trips/Photos" Target="Photos"/>
          <NavigationPropertyBinding Path="Photo" Target="Photos"/>

Thanks

OData V4 $entity does not work.
According to the specs,

http://services.odata.org/V4/TripPinServiceRW/$entity?$id=People%28%27russellwhyte%27%29

How did you generate swagger trippin.json for OData?

We need a tool for this, like OData swagger generator, so any WebAPI OData project can easily be used in Azure AppService.

Trippin service is launched last year. Since then, many features added into Web API OData. For example:

1. Complex Inheritance,
2. Function/action enhancement
3. Reference constraint.
   ...

Please find time to add these features into Trippin service. Thanks.

For the references and for the schema itself please introduced aliases and used them in all places (get rid of the lengthy namespaces for qualified names), this makes the metadata document much more readable.

Unfortunately I can't upload a sample file here.

I looked at OData function/action examples ODataActionsSample & ODataFunctionSample from https://github.com/OData/ODataSamples to learn how to add functions eg.

- we prefix functions with [HttpGet] in a ODataController class,
- in WebApiConfig::Register(), declare the function and add to the model

then calling functions via web URLs magically work!

However, the DynamicEdmModelCreation sample uses extremely different approach to adding controllers/datasources since it uses one controller called HandleAllController. and makes sure of helper classes:

CustomODataRoute
DynamicModelHelper

so I can't figure out how to add functions/actions to this project.

I've studied/debug and think there's something I need to do with MatchAllRoutingConvention::SelectAction()

if (odataPath.PathTemplate == "~/unboundfunction")
return "FunctionName";

But it says function not found.
Is there a proper way to add functions to DynamicEdmModelCreation sample project?

`http://services.odata.org/V4/Northwind/Northwind.svc/Employees/?$filter=contains(toupper(FirstName),%27C%27)

http://services.odata.org/V4/Northwind/Northwind.svc/Employees/?$filter=contains(tolower(FirstName),%27C%27)`

this is query string but it always return both lower and uppercase

I wondering if anyone has sucessfully mananged to build & run DynamicEdmModelCreation project in V6/6.1 beta?

Hi
for the lateset version is there any example on how to develop a serialization formatter ?
the examples in the repository seems to be outdated
thanks

It looks like there has been some divergence between the sample code in https://github.com/OData/ODataSamples/tree/master/Scenarios/TripPin and the deployment of the sample service at http://services.odata.org/V4/TripPinServiceRW.

This is made more clear by comparing the metadata document obtained from a local deployment of master and the metadata document on the deployed example. The deployed document contains annotations which are not defined in the current sample code.

Keeping these in sync will help make this a better resource for people learning to use and implement OData services. The simplest fix is to push changes to this repository.

I am trying to add child record in ODataUntypedSample project. How can I do that?
Detailed question.

I just tried to make a few requests with Postman to the live TripPin service with OData-MaxVersion header set to different values... But the service seems to completely ignore it. Yet, this is a requirement of the Minimal Conformance Level:

In order to conform to the OData Minimal Conformance Level, a service MUST conform to the semantics the following headers, or fail the request

• 5.1. Accept (section 8.2.1)
• 5.2. OData-MaxVersion (section 8.2.7)

Using elements from namespaces not inlcued in the document requires the use auf edmx:reference.
You need to add as children of edmx:Edmx

<edmx:Reference Uri="http://docs.oasis-open.org/odata/odata/v4.0/os/vocabularies/Org.OData.Core.V1.xml">
    <edmx:Include Alias="Core" Namespace="Org.OData.Core.V1"/>

Any idea? Cheers.
