MongoDB documentation talks about how a document validator could be defined on a collection which could be triggered during insert or update.
For example, a collection with email field could be validated using a regex and the insert may succeed or fail depending upon how the collection has been configured at the time of creation.
I have not been able to find similar capability for C# driver for MongoDB.
Is this not supported yet?
This ship may have sailed, but if others stumble across this question. This has been implemented.
The mainline C# driver as well as the legacy C# driver support document validation. As you see in the documentation, you set a validator when you create a collection (or by using collMod to add a validator to an existing collection, but I won't discuss this further). The driver includes properties inside the CreateCollectionOptions class for the Validator document, the ValidationAction, and ValidationLevel. CreateCollectionOptions is the second argument you pass to the CreateCollection function. Here is the source code and a test that creates a collection with a simple validator and another.

I have embedded Teiid 12.3 in a Spring Boot application. I want to get into the metadata of my VDB in order to generate a diagram using graphviz-java. I assume that if I have a org.teiid.metadata.Table object, I can call getIncomingObjects() to get references to tables that table depends on. I just can't figure out how to navigate from the EmbeddedServer to the Table objects.
I looked into using the administration API available via EmbeddedServer.getAdmin(). From there, I can call getVDBs(), and from there I can navigate down to getModels(), but below that level there is only the model source via getSourceMetadataText(). I also tried subclassing EmbeddedServer to make getVDBRepository() public. I can call getVDBRepository()*.getModels(), but it returns the same Model objects only get me access to the source definition of the models, not the runtime metadata model.
I tried getVDBRepository().getSystemStore() and VDBRepository.getODBCStore(), but those MetadataStores are not for the VDB I have deployed.
I haven't found any examples by Google, Teeid JIRA, Teiid forum, or StackOverflow to help me.
Take look at [1] the getSchema method on Admin API, this method returns the string form of the metadata, however you can grab Schema object for object form. If you do not want that way, Teiid also exposes system catalog using many SYS tables, you can issue SQL queries to grab the metadata of schemas and schema items in a VDB. One for internal access, another is from external access.
BTW one of users created a dependency diagram tool that may be useful if you are trying to do something similar. See [2]. Let me know if you interested in pushing that further.

I have some plugin's which are basically input and output type definitions. I have a generic controller which i can add to the mvc pipeline. All works fine.
but I'm having trouble setting the api version on this generic controller. I know you can set this based upon an attribute on top of the controller class. But since you can't have this dynamic (attribute) don't allow it, i have no way to set the version for each instance of the generic controller.
Currently i just compile the controller for each instance on runtime and register i using the roslyn compiler.
is there a way to set the api-version somewhere in the pipeline of registering controllers in the mvc pipeline and endup with different api versions endpoints.
This can be achieved by using the Conventions API. It was designed to support this exact type of scenario:
https://github.com/microsoft/aspnet-api-versioning/wiki/API-Version-Conventions
This will only work on closed-generics, but it shouldn't be too much work to make that happen. Here's a couple of basic examples:
// typed, closed generic
options.Conventions.Controller<GenericController<PlugIn1>>().HasApiVersion(1,0);
// untyped, closed generic
var controllerType = typeof(GenericController<>).MakeGenericType(new []{typeof(PlugIn1)});
options.Conventions.Controller(controllerType).HasApiVersion(1,0);
You can also author your own custom conventions a la IControllerConvention. This approach could be used to version all controllers that inherit from GenericController<>. Then you just need to add it to the conventions like this:
options.Conventions.Add(new PlugInControllerConvention());
Hopefully that's enough to get you started. Feel free to ask more questions.
How do I run/call/kickoff an external program (custom code) whenever certain attributes or objects are added or modified in OpenDJ’s database?
Here is my real world need. (Feel free to change my thought direction entirely).
Whenever a new email address gets created or changed in the OpenDJ database I want to initiate some java code that does some email verification/validation (send the “click here” link with a token to prove the user owns the email they just signed up with).
I know, I could use OpenIDM/AM to accomplish this but to take this a step further I need to validate other information and other credentials (custom) which users supply that are not supported by OpenIDM/AM suites.
Initiating/calling custom code upon ADD or MODIFY of specific objects and attributes is what I want and would like to know how to accomplish this. Preferably without having to scrape logs.
Please Help.

OpenDJ has a plugin interface where you can plug Java calls on Add or Modify. A sample of this kind of plugin is the attribute uniqueness which verifies that some attributes have a unique value in the directory.
The plugin interface javadoc can be found here : http://docs.forgerock.org/en/opendj/2.6.0/javadoc/org/opends/server/api/plugin/DirectoryServerPlugin.html
I have a classic asp app that uses XML data binding. With the IE9 emulation setting it works fine up through version IE10. But in IE11, the recordset is always null. The values, however, are bound correctly to the input fields using #DATASRC and DATAFLD. It's just when I attempt to access a particular record via recordset.absolutePosition, it bombs.
Since data binding seems to be functioning, surely there must be a way to specify a particular row of the data.
The datasrc and datafld APIs have been removed in IE11 partly for security reasons:
Example: The following use of data binding will result in the execution of script within IE:
<xml id=cdcat><note><to>%26lt;span style=x:exp<![CDATA[r]]>ession(alert(3))%26gt;hello%26lt;/span%26gt;</to></note></xml><table border=%221%22 datasrc=%22%23cdcat%22><tr><td><span datafld=%22to%22 DATAFORMATAS=html></span></td></tr></table>
Note there is no SCRIPT tag present. There are many similar obscure script execution techniques present in all browsers.

I am writing an MVC 3 application and I am trying to implement my own custom membership provider (following the sample in Apress' Pro ASP.NET MVC 3 Framework).
I created my custom class, inherited from MembershipProvider and (using ReSharper) implemented all 27 of the methods with NotImplementedExceptions.
Now, I have overridden the ValidateUser method as the book states and it works fine, but I would like to make my provider more robust and implement the other methods (e.g. set MinRequiredPasswordLength and GetNumberOfUsersOnline).
Is there some sample code that I can use to start populating these methods that I can tweak to fit my own DB/Model schema?
I can certainly use trial and error to figure it out, but a base code sample would greatly help.
EDIT:
This question was just downvoted twice. If you are going to downvote, please post a comment as to why so that I can work on improving my questions.
EDIT 2:
For example, for the following method:
public override int GetNumberOfUsersOnline()
{
throw new System.NotImplementedException();
}
I can try to write code from scratch to look at some web log, determine the users login time and approximate if they are still on, but that will take a large amount of time for me to figure out. Since all this code is from the same interface that Microsoft wrote for the standard SqlMembershipProvider, isn't there code out there (even from MS) that contains this method? If so, I want take it, modify it so it uses my DB schema instead of the aspnetdb default schema. I would prefer to have some sort of base code to work from. I thought this would be a simple and fairly standard request, but perhaps not.
You can't use the default provider's code for your custom provider, that is why you are implementing a custom one, to tweak it according to your requirements, use your own db tables etc.
Take a look at my blog posts about custom membership, custom role providers and custom membership user. There is an example there of how you can use your own database to get/set membership information.
Here's a of sample implementation of custom MembershipProvider on MSDN.
