New Post: VS2010 WCF Data Service metadata namespace not supported

juanar — Mon, 22 Feb 2010 23:08:06 GMT

Hi team,

We are working on some HOL samples using the PHP ADO.NET Data services toolkit with the latest VS2010 RC bits and we found a problem related to the EDM namespace used in the generated WCF (formerly ADO.NET) Data Service $metadata response.

Below you can find a sample $metadata response. Notice the bolded edm namespace:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?> 
- <edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx">
- <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0">
+ <Schema Namespace="AdventureWorksShoppingModel" 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/2008/09/edm">

This namespace is not supported in the ADODotNETDataServices2PHPProxy.xsl file. We've workaround the issue by hacking the file to support this new version of the namepspace:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"
    xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices"
    xmlns:schema_1_0="http://schemas.microsoft.com/ado/2006/04/edm"
    xmlns:schema_1_1="http://schemas.microsoft.com/ado/2008/09/edm"
xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
  <!--Removed Entity Data Model schema-->
  <!--xmlns:schema_1_1="http://schemas.microsoft.com/ado/2007/05/edm"-->

The approach above worked for us in this specific scenario, but we are pretty sure hacking the xsl file is not the best approach. You might have another solution in mind.

We hope you can find this info useful for your next release.

Thanks in advance,

Juan Arguello

New Post: How do you encode spaces in a query with a filter?

vpedroza — Fri, 23 Oct 2009 19:22:36 GMT

The following query with a filter works when issued from a browser

Customer(customerId='VE1')/orders?$filter=orderDate ge datetime'2009-10-16T00:00:00' and orderDate le datetime'2009-10-20T23:59:59.99'

When I attempt to execute it programatically, it fails.

$rangeResult = $proxy->ExecuteQuery("Customer(customerId='$customerId')/orders?\$filter=orderDate ge datetime'$lowDate' and orderDate le datetime'$hiDate'");

The spaces were turned into + signs.

Customer(customerId='VE1')/orders?$filter=orderDate+ge+datetime%272009-10-17T%3A00%3A00%3A00%27+and+orderDate+le+datetime%272009-10-21T%3A23%3A59%3A99%27

When I try substituting the spaces with %20 it also fails, the %20 gets turned into %2520

$rangeResult = $proxy->ExecuteQuery"Customer(customerId='$customerId')/orders?\$filter=orderDate%20ge%20datetime'$lowDate'%20and%20orderDate%20le%20datetime'$hiDate'");

Customer(customerId='VE1')/orders?$filter=orderDate%2520ge%2520datetime%272009-10-17T%3A00%3A00%3A00%27%2520and%2520orderDate%2520le%2520datetime%272009-10-21T%3A23%3A59%3A99%27

New Post: Unable to load propery order "orderDetails"

vpedroza — Mon, 19 Oct 2009 19:30:49 GMT

Looking at the original Northwinds Data Service I see that the OrderID was Type="Edm.Int32".
In the service I am using I see that it is Type="Edm.Int64". Peeking at
adodotnetservcesphp\Contect\ObjectContext.php LoadProperty() function I see that it is
really generating a query. I have been able to workaround the support issue of int vs long
by generating my own query and working with the result. Is this something that will be
supported in the future?

//$proxy->LoadProperty($order, "orderDetails");
$orderDetailResult = $proxy->ExecuteQuery("Order(customerId='".$customerId."',orderId=".$order->orderId."L)/orderDetails");

New Post: Unable to load propery order "orderDetails"

vpedroza — Mon, 19 Oct 2009 18:13:52 GMT

Attempting to load orderDetails for an order fails. The generated query
with orderId=1 fails but works when manually issued with orderId=1L.

I would apprecate any suggestions, Thanks, Vince...

--> The following line works and generates the request : GET /vvvvRestSVT2/vvvNorthwindSVTDataService.svc/Customer(customerId='VP1')/orders HTTP/1.1
    $proxy->LoadProperty($customer, "orders")
    foreach($customer->orders as $order) {
------> The following line generates the follwing request which fails : GET /vvvRestSVT2/vvvNorthwindSVTDataService.svc/Order(customerId='VP1',orderId=1)/orderDetails HTTP/1.1

New Post: How do you set a link? (SetLink vs AddLink)

vpedroza — Wed, 14 Oct 2009 18:50:40 GMT

How do you SetLink?

WHen running the Northwithnds simple sample7, the following code
adds to the $cust collection of links a link to the new order
$newO.

$proxy->AddLink($cust, "Orders", $newO);

I want to add a link to the $newO back to the $cust.

   $proxy->AddLink($cust, "Orders", $newO);
    proxy->AddLink($newO, "Customers", $cust)

This fails as follows

   Error: Th   e URI 'http://mulder.rchland.ibm.com:1325/NorthwindWeb/NorthwindData
   Service.svc/$2/$links/Customers' is not valid for POST operation. For POST opera
   tions, the URI must refer to a service operation or an entity set.<br>Detailed E
   rror:

Since it is not a collection of links I tried SetLink but that is
not defined.

$proxy->AddLink($cust, "Orders", $newO);
$proxy->SetLink($newO, "Customers", $cust);

PHP Fatal error: Call to undefined method NorthwindEntities::SetLink() in C:\Hmm
m\Sample7.php on line 51

How do I go about adding a link from the order back to the
customer?

New Post: Config Issue - adodotnetservicesphp_path

anu_chandy — Tue, 29 Sep 2009 05:16:58 GMT

Hi Nickknyc,

Did you restart IIS after changing PHP.INI ? if not can you try it?

For adding php_xsl.dll, Please follow the below steps:

1. Download the PHP zip package in a temporary folder from http://www.php.net/downloads.php corresponding to your PHP version

2. Extract the zip, from %Temporary Folder%\PHP version\ext\ copy php_xsl.dll to ext directory of your PHP installation directory.

3. Restart IIS

Thanks

Anu

Any thoughts?

New Post: What type of data should I be creating/using for the date fields?

anu_chandy — Fri, 18 Sep 2009 03:29:04 GMT

Hi Rob,

In our client application we can use string to represent date. For example:

$order = $proxy->ExecuteQuery("Orders(OrderID=10248)");
$order[0]->OrderDate = '2008/05/07';
$proxy->UpdateObject($order[0]);
$proxy->SaveChanges();

The above code will fetch the first Order record from Orders table of NorthWind database and update the OrderDate column to 2008/05/07. We can represent date in yyyy/mm/dd format.

Thanks & Regards,

Anu

RobWisniewski — Tue, 15 Sep 2009 05:38:33 GMT

Forgive me I haven't seen any information in any of the docs on this, and I believe I may have read them back to front a few times by now. =) What type of data should I be using for a field which the proxy identifies as 'Edm.datetime'?

This is obviously a date or timestamp in the data model. I've tried a few things but can't figure out what data type in php it's expecting.

RobWisniewski — Tue, 15 Sep 2009 05:36:16 GMT

You're absolutely right.. that works (as does using the ->AddToCustomers() method which I didn't see before)..

What's interesting is the that the user's guide is wrong. copies from the user's guide:

require_once 'MyProxyClass.php';

$proxy = new NorthwindEntities();

/* Create a Customers php Object */

$customer = Customers::CreateCustomers("CHAN9", "channel9");

/* inserting Customers object context tracking system */

$proxy->AddObject($customer, ‘Customers’);

/*SaveChange insert the object into data service*/

$proxy->SaveChanges();

anu_chandy — Tue, 15 Sep 2009 05:12:12 GMT

Hi Rob,

The way you are invoking the AddObject function is wrong, Instead of

$proxy->AddObject($newCustomer, 'Customers');

you should invoke it as:

$proxy->AddObject('Customers', $newCustomer);

The first argument of AddObject is the EntityType and second is the entity instance.

Thanks & Regards,

Anu

New Post: Getting an exceptioni with no message when adding object

RobWisniewski — Mon, 14 Sep 2009 08:23:41 GMT

I'm trying to get up to speed with the libraries here and write a couple samples against a previous northwind data service which I used to learn some Silverlight development with. Everything worked find creating the proxies from the command line and even with my first php cases doing some fairly complex queries. I can't do a simple customer insert, however, despite using almost the exact same code as described in the user guide.

Here's my php:

require_once 'northwinddb.php';
require_once 'svt_functions.php';
define("NORTHWIND_SERVICE_URL", "http://localhost:999/Northwind.svc");

$proxy = new NorthwindEntities(NORTHWIND_SERVICE_URL);

$newcid = rand_str(5);
$newCustomer = Customers::CreateCustomers($newcid, "company_".$newcid);
// $newCustomer->ContactName = "cont_".$newcid;
// $newCustomer->Address = "add_".$newcid;
// $newCustomer->City = "cty_".$newcid;
// $newCustomer->Region = "reg_".$newcid;
// $newCustomer->PostalCode = rand_str(5, "0123456789");
// $newCustomer->Phone = rand_str(7, "0123456789");
// $newCustomer->Fax = rand_str(7, "0123456789");

echo "<p>Adding Customer: ".$newCustomer->CustomerID."</p>\n";

try
{
  $proxy->AddObject($newCustomer, 'Customers');
  $proxy->SaveChanges();
} 
catch (Exception $e) 
{
    echo 'Caught exception: ',  $e->getMessage(), "\n";
    var_dump($e->getTrace());
}

And here's the output:

Adding Customer: vwbv6

      string(9) "Customers"
    }
  }
}

Any ideas? I looked at the ObjectContext.php file at line 123, and I just can't find a way that an exception would be thrown without a message. Thanks for the help

Hi Phani,

There is no specific need for .BAK file. We will include MDF file in our next release. If user already have Northwind sample database, he can just modify settings in web.config file, as you did.

New Post: Generated create object method takes in readonly properties

mcm_ham — Tue, 08 Sep 2009 23:38:12 GMT

| Astoria doesn't yet have a concept of read-only properties.

Strange, because this is working perfectly fine for me on dotnet and php clients. On the dotnet client the property only has a getter causing a compilation error if you try to set it. That said the main discussion in the thread was the ability to add your own propeties if you are exposing the Entity Data Model through the Data Service and indeed the custom properties do not come through.

New Post: /Data folder in samples contains Northwind.BAK , why not the MDF file ?

Phanatic — Tue, 08 Sep 2009 06:51:24 GMT

Hi ,

I downloaded the sample and was trying to install it when I saw that the sample databases for the ADODotNetDataServices project have a .BAK file for northwind.
Will this work against the sample northwind schema ?I tried this against a local install of northwind and get an error message about the .BAK file being
incompatible for my database schemas. Admittedly , pointing the dataservice to my local install of northwind by changing the connection string in web.config worked.
I am just curious as to why we needed to include the .BAK file and not the MDF file.
