Inserting new records(entities) in OData 2.0 using Olingo



Hi all ,

 I need to insert new record in database using existing OData
service. I came across ODataSingleProcessor.createEntity(PostUriInfo uriInfo, InputStream
content, String requestContentType, String contentType) API
which shows me how to write entity.  Please guide me how to call this
API. 
Suppose I have product service deployed on server
then,





1) While filtering it sends parameters in $filter
argument similarly for insert operation what is the format of URI
required so that createEntity method will  be invoked ?
2)
Similarly I need to implement UPDATE and DELETE operations too.
3)
Is this the correct way to achieve my goal ? If yes then any link to it
will be appreciated.

 
4) From browser side I am using basic HTML
and JS to call OData service. I dont see any JS API support from olingo
for V2.0. Guide me to client side consumption as well for
V2.0.

Thank you.

		Hi Joshi,
	
		 
	
		Yes, you do a POST request with the data (e.g. as JSON) as body
(payload) to the according EntitySet URL.
	
		Olingo then dispatches this request to the â&euro;žODataResponse
createEntity(â&euro;¦)â&euro;&oelig; method of your
â&euro;žEntitySetProcessorâ&euro;&oelig; implementation for
processing by the service developer.
	
		Now the service developer has to handle by itself the creation of the
data in e.g. a database.
	
		However Olingo provides methods to parse/deserialize the body via the
EntityProvider (e.g.
â&euro;žreadEntry(â&euro;¦):ODataEntryâ&euro;&oelig;).
	
		Afterwards you have to send back the according response via an
â&euro;žODataResponseâ&euro;&oelig; object which contains
the HTTP status code (e.g. 201 created) and the new created entity (e.g.
as JSON) as response body payload.

		From the the OData specification it seems that we have to send data in
body of POST request with corresponding content - type.

		And further this data can be extracted in createEntity() method.

Hi Joshi,


Yes, you do a POST request with the data (e.g. as JSON) as body (payload) to the according EntitySet URL.
Olingo then dispatches this request to the „ODataResponse createEntity(…)“ method of your „EntitySetProcessor“ implementation for processing by the service developer.
Now the service developer has to handle by itself the creation of the data in e.g. a database.
However Olingo provides methods to parse/deserialize the body via the EntityProvider (e.g. „readEntry(…):ODataEntry“).
Afterwards you have to send back the according response via an „ODataResponse“ object which contains the HTTP status code (e.g. 201 created) and the new created entity (e.g. as JSON) as response body payload.


Best Regards,
Michael
