WebApi Odata: remove metadata from response - odata

I'm developing an WebApi Odata service for internal usage. I want to remove from response at server all additional data except serialized data.
I want to remove all this stuff:
{
"#odata.context":"http://192.168.150.86:9933/odata/$metadata#Terminal","value":[
]
}
and leave here only array of "Terminal"
is there any way to do this?

Add the following option to your query string:
$format=application/json;odata.metadata=none
This will remove the odata metadata from your results.

This is how it can be accomplished.
var ODataJSON = JsonConvert.DeserializeObject<JObject>(json);
ODataJSON.Property("#odata.context").Remove();
ODataJSON.Add("Terminal", ODataJSON["value"]); //adding Terminal attribute
ODataJSON.Property("value").Remove(); // removing default value attribute.

You can also set the Accept header
Accept: application/json;odata.metadata=none

Let's assume that you are writing a new function that returns IHttpActionResult. To return the data you can use the Json method. It removes the metadata

Fetching data from a microservice to rest in grails

I have a rest and a microservice.In microservice i have a table and i want that table data to be fetched to rest and i have written the below way in a rest demoController.
def result = restBuilder().post("http://localhost:2222/api/microservice/fetchData"){
header 'authorization', 'fdgtertddfgfdgfffffff'
accept("application/json")
contentType("application/json")
json "{'empId':1,'ename':'test1'}"
}
But it throws an error "No signature of method: demoController.restBuilder() is applicable for argument types: () values: []".How should i fetch data from a microservice to rest?
You are calling a method named restBuilder() and that method does not exist. If you want that to work, you will need to implement that method and have it return something that can deal with a call to post(String, Closure).
You probably are intending to use the RestBuilder class. The particulars will depend on which version of Grails you are using but you probably want is something like this...
RestBuilder restBuilder = new RestBuilder()
restBuilder.post('http://localhost:2222/api/microservice/fetchData'){
header 'authorization', 'fdgtertddfgfdgfffffff'
accept 'application/json'
json {
empId = 1
name = 'test1'
}
}
You may need to add a dependency on grails-datastore-rest-client in your build.gradle.
compile "org.grails:grails-datastore-rest-client"
I hope that helps.

OData : Why am I getting HTTP 428 (Precondition Required) error while performing an update

So here's my code
sap.ui.getCore().getModel("myModel").update("/ZSystemNameSet(mandt='001')", data, null, function(datay, responsey){
sap.ui.getCore().getModel().refresh();
MessageToast.show("It worked...!! Data: "+datay+"Response: "+responsey);
}, function(datax,responsex){
MessageToast.show("Sorry! Data: "+datax+"Response: "+responsex);
});
Also how do I add the header attributes to the update() call?
Obviously your service uses optimistic locking and expects an If-Match header, containing the ETag of the entity, in the request. You can pass this ETag as parameter to the update method. For further details you should check your service definition and the documentation.
Regarding the update of header attributes: It is hard do answer as there is no information regarding your entity orchestration. Normally you should be able to add a property containing the update information for you header to the data structure you send to the server, e.g. if the header is reachable from your entity ZSystemName via association "Header" you do the following:
data.Header = { "attribute1" : value1, "attribute2" : value2 }

SAPUI5 ODataModel metadata $format=xml

i am trying to connect sapui5/openui5 ODataModel to an odata-server. I want to use a nodejs server with package simple-odata-server. Unfortunately this odata server provides metadata only in xml-format. But sapui5 tries to load metadata in json-format.
Before i switch to another odata server, i want to check, wether sapui5 can load metadata in xml-format. I tried to create the model with several parameters, but ODataModel still tries to load metadata as json.
var oModel = new ODataModel("/odata", {
"metadataUrlParams": "$format=xml",
"json": false
});
Does anybody know, wether i can switch to $format=xml
Thanks in advance,
Torsten
As far as I know the OData protocol metadata is always provided as XML, never seen metadata in JSON format. Also my n-odata-server Qualiture mentioned in the comment above does it. But I never had problems with SAPUI5. It requests the metadata, gets the xml stream and works with it.
Since the metadataUrlParams parameter is of type map I'd suppose it would at least do what you intend like this:
var oModel = new ODataModel("/odata", {
"metadataUrlParams": {
"$format": "xml"
}
});

get 'undefined' saveResult.entities after saveChanges [breezejs]

I tried to update one entity in my angularjs client using breezejs library. After calling saveChanges(), it can actually save back in the server and fetched on the client. However, the server did not return the response back. The saveResult.entities is undefined and pop up an error for me. When I took a look at the docs, it mentions 'Some service APIs do not return information about every saved entity. If your server doesn't return such information, you should add the pre-save, cached entity to saveResult.entities yourself'. Could anyone provide an example of how to do this?
This is the code when i am trying to do an update.
manager.saveChanges(entitiesToSave, null, (saveResult) => {
const savedRes = saveResult;
savedRes.entities = entitiesToSave;
return savedRes;
}).then(saveSucceeded);
On the server, you would need to construct the response for an update similar to the way it is for a create:
response.setContent(...); // entities
response.setStatusCode(HttpStatusCode.OK.getStatusCode());
response.setHeader(HttpHeader.CONTENT_TYPE, responseFormat.toContentTypeString());

Jersey POST operation with PathParam and JSON Object

By design, GET operation should be used only for read Only operation. Howeevre,i am looking for a plausible way of implementaion of following.Implement a POST operation that can be called as it is mentioned below
POST /my-store/order/D : where D is the day the customer place an order
Request: POST /my-store/order/14
{
"customer" : "XYZ",
"order" : {
"item1" : 2
}
}
I tried implementing using below function
#Path("/D")
#POST
#Consumes({ MediaType.TEXT_PLAIN, MediaType.APPLICATION_JSON })
#Produces({ MediaType.APPLICATION_JSON })
public Response submitOrder(#PathParam("D") int elapsedDays, #Context UriInfo uriInfo, Order orderInfo){
..........
}
But the above implementation does not seem to working. When I try to test the implementation using MyEclipse REST explorer ,it does not offer option to pass in Order object but allow 'D' parameter only. However, if #PathParam and #Path is removed then it works perfectly fine i.e. allows to consume JSON Order object.
But,the requirement is to pass the days as Path parameter and Order object as JSON input in POST request.
Looking for suggestion on implementation approach and design approach.
Thanks in advance
For one thing, your path should be configured like this:
#Path("/{D}")
I assume your extended ellipses means you have some method parameter that represents the deserialization of your order.
