I am looking to writing to an existing OData service from an Android device.
Our existing .Net client is currently using this service and I am having
trouble with addLink/setLink methods on the ext.OData library from restlet.org.
I have created my classes from our OData service as recommended on the
restlet.org site and reading the data works fine. When I try to write I have
issues if I try to write more than a single entity; for instance if I try to
add a link. I have a customer object that contains orders so I am attempting to
use the following code:
private static List<Customer> customers = new Vector<Customer>();
private static DbAdapter helper = null;
private static DataService ds = new DataService();
public static processOutboundData(Context ctx) {
helper=new DbAdapter(mCtx);
helper.open();
// Get the outbound customers from SQLite DB
customers = helper.readCustomers(WhereExtra, null);
helper.close();
for (Customer myCustomer : customers{
if (myCustomer.getCustomerId()==0) {
try {
// add the customer details
ds.addLink(myCustomer, "Detail", myCustomer.getDetail());
// Add this customers orders
for (Order thisOrder : myCustomer.getOrder()) {
ds.addLink(myCustomer, "Order", thisOrder);
ds.setLink(thisOrder, "Customer", myCustomer);
}
ds.addEntity(myCustomer);
} catch (Exception addEx) {
Log.w(TAG, "The Add Entity Failed Due To " + addEx.toString());
}
} else {
try {
ds.updateEntity(myCustomer);
} catch (Exception updEx) {
Log.w(TAG, "The Update entity Failed Due To " + updEx.toString());
}
}
}
}
When this code executes I get a error (405) Method Not Allowed Can’t add entity
to this set Message. What am I doing wrong here? I thought I would need to
set/add the link before I did an add or update on the entity (I did not
complete the update code because I wanted to finish create first).
The other part of my questions is on the parameters of addLink/setLink
Parameters:
source The source entity to update. (I understand this one)
sourceProperty The name of the property of the source entity. (What exactly is
this)
target The entity to add to the source entity. (I understand this one)
Being that there are no examples that I could find and the documentation is
ambiguous I thought I would ask directly. What is the sourceProperty? Is it the
Table/Entity name or the foreign key column name? or something else entirely?
