I need to execute a command that is part of my migration scripts (mongock java library) conditionally based on Mongo version
In case Mongo version is lower then 4.2 I need to execute this command. For Mongo 4.2 and higher it should not be executed.
db.getSiblingDB('admin').runCommand( { setParameter: 1, failIndexKeyTooLong: false } )
Is there a way how to do it?
Thank you,
Lukas
don't know if you already found a solution for this.
The idea is to figure out the Mongo's version inside the changeSet and then perform the required actions.
I will assume you are using the last Mongock's release for version 3.x.x, which is 3.3.2 or 4.0.x.alpha, so you should use MongockTemplate, instead of MongoTemplate. Don't worry, it's just a wrapper/decorator, you won't miss anything from the original API.
So you can do something like this:
#ChangeSet(id = "changeset-1", order = "001", author = "mongock")
public void changeSet(MongockTemplate mongockTemplate, ClientRepository clientRepository) {
String version = mongockTemplate.executeCommand(new Document("buildinfo", new BsonString("")))
.get("version")
.toString();
if(getNumericalVersion(version) < 42) {
//do your actions
} else {
//do you other actions
}
}
NOTE 1: We don't recommend using executeCommand. In this case, for taking the version it's fine, but in general we recommend not using it, specially for writes.
NOTE 2: Currently we are working on version 4, which will allow to scan multiple packages and even isolated ChangeLog classes. So another approach would be to take the version in the bean creation and inject the change or not depending on the MongoDB's version
I want to ask why the query builder class does not included NOT BETWEEN. The hack i try was this
->where('"mytable.date" not between '." $min_date ".' AND '. "$max_date").
It built this query AND "mytable"."date" "not" between "2017-5-18" AND 2017-6-7.
How can i effectively used this with the codeigniter query builder class or active records.
I am using postgresql driver.
I'm confused about your quotations may you try using this code below instead.
$this->db->where("mytable.date NOT BETWEEN '$min_date' AND '$max_date'");
UPDATE
I tried NOT BETWEEN and really doesn't work. another alternative is
$this->db->where('mytable.date <=', $min_date);
$this->db->where('mytable.date >=', $max_date);
Please try the code below that will work fine in my code:
$this->db->where("'mytable.date' NOT BETWEEN '".$min_date."' AND '".$max_date."'");
How do I "tell" EF to log queries globally? I was reading this blog post: EF logging which tells in general how to log sql queries. But I still have a few questions regarding this logger.
Where would I need to place this line context.Database.Log = s =>
logger.Log("EFApp", s);?
Can it be globally set? Or do I have to place it everywhere I do DB
operations?
In the "Failed execution" section, the blogger wrote that, and I
quote:
For commands that fail by throwing an exception, the output contains the message from the exception.
Will this be logged too if I don't use the context.Database.Log?
Whenever you want the context to start logging.
It appears to be done on the context object so it should be done every time you create a new context. You could add this line of code in your constructor though to ensure that it is always enabled.
It will not log if you do not enable the logging.
I don't recommend to use that's functionality, because, it hasn't reason to exists in the real case.
Thats it use a lot of to debug code only. But, wether you wanna know more than details ... access link... https://cmatskas.com/logging-and-tracing-with-entity-framework-6/
In this case you can put code like this
public void Mylog()
{
//Thats a delegate where you can set this property to log using
//delegate type Action, see the code below
context.Database.Log = k=>Console.Write("Any query SQL")
//Or
context.Database.Log = k=>Test("Any query SQL")
}
public void Test(string x){
Console.Write(x)
}
I hope thats useufull
I am using factory_girl and rspec2 for my testing. I have an issue with the following code:
let(:book) { build(:book, id: 1) }
book_path(book)
book_path statement is generating /books url instead of /books/1. I can use create, but any suggestions on how to fix this using build strategy?
I am using
rspec-rails (2.11.0)
factory_girl (3.5.0)
Try book.to_param (that's actually what book_path(book) is doing under the hood) and see what it returns. By default to_param returns id, but your book is not saved yet, so it can return nil.
I'm looking specifically for a way to automatically hyphenate CamelCase actions and views. That is, I'm hoping I don't have to actually rename my views or add decorators to every ActionResult in the site.
So far, I've been using routes.MapRouteLowercase, as shown here. That works pretty well for the lowercase aspect of URL structure, but not hyphens. So I recently started playing with Canonicalize (install via NuGet), but it also doesn't have anything for hyphens yet.
I was trying...
routes.Canonicalize().NoWww().Pattern("([a-z0-9])([A-Z])", "$1-$2").Lowercase().NoTrailingSlash();
My regular expression definitely works the way I want it to as far as restructuring the URL properly, but those URLs aren't identified, of course. The file is still ChangePassword.cshtml, for example, so /account/change-password isn't going to point to that.
BTW, I'm still a bit rusty with .NET MVC. I haven't used it for a couple years and not since v2.0.
This might be a tad bit messy, but if you created a custom HttpHandler and RouteHandler then that should prevent you from having to rename all of your views and actions. Your handler could strip the hyphen from the requested action, which would change "change-password" to changepassword, rendering the ChangePassword action.
The code is shortened for brevity, but the important bits are there.
public void ProcessRequest(HttpContext context)
{
string controllerId = this.requestContext.RouteData.GetRequiredString("controller");
string view = this.requestContext.RouteData.GetRequiredString("action");
view = view.Replace("-", "");
this.requestContext.RouteData.Values["action"] = view;
IController controller = null;
IControllerFactory factory = null;
try
{
factory = ControllerBuilder.Current.GetControllerFactory();
controller = factory.CreateController(this.requestContext, controllerId);
if (controller != null)
{
controller.Execute(this.requestContext);
}
}
finally
{
factory.ReleaseController(controller);
}
}
I don't know if I implemented it the best way or not, that's just more or less taken from the first sample I came across. I tested the code myself so this does render the correct action/view and should do the trick.
I've developed an open source NuGet library for this problem which implicitly converts EveryMvc/Url to every-mvc/url.
Uppercase urls are problematic because cookie paths are case-sensitive, most of the internet is actually case-sensitive while Microsoft technologies treats urls as case-insensitive. (More on my blog post)
NuGet Package: https://www.nuget.org/packages/LowercaseDashedRoute/
To install it, simply open the NuGet window in the Visual Studio by right clicking the Project and selecting NuGet Package Manager, and on the "Online" tab type "Lowercase Dashed Route", and it should pop up.
Alternatively, you can run this code in the Package Manager Console:
Install-Package LowercaseDashedRoute
After that you should open App_Start/RouteConfig.cs and comment out existing route.MapRoute(...) call and add this instead:
routes.Add(new LowercaseDashedRoute("{controller}/{action}/{id}",
new RouteValueDictionary(
new { controller = "Home", action = "Index", id = UrlParameter.Optional }),
new DashedRouteHandler()
)
);
That's it. All the urls are lowercase, dashed, and converted implicitly without you doing anything more.

Have you tried working with the URL Rewrite package? I think it pretty much what you are looking for.
http://www.iis.net/download/urlrewrite
Hanselman has a great example herE:
http://www.hanselman.com/blog/ASPNETMVCAndTheNewIIS7RewriteModule.aspx
Also, why don't you download something like ReSharper or CodeRush, and use it to refactor the Action and Route names? It's REALLY easy, and very safe.
It would time well spent, and much less time overall to fix your routing/action naming conventions with an hour of refactoring than all the hours you've already spent trying to alter the routing conventions to your needs.
Just a thought.
I tried the solution in the accepted answer above: Using the Canonicalize Pattern url strategy, and then also adding a custom IRouteHandler which then returns a custom IHttpHandler. It mostly worked. Here's one caveat I found:
With the typical {controller}/{action}/{id} default route, a controller named CatalogController, and an action method inside it as follows:
ActionResult QuickSelect(string id){ /*do some things, access the 'id' parameter*/ }
I noticed that requests to "/catalog/quick-select/1234" worked perfectly, but requests to /catalog/quick-select?id=1234 were 500'ing because once the action method was called as a result of controller.Execute(), the id parameter was null inside of the action method.
I do not know exactly why this is, but the behavior was as if MVC was not looking at the query string for values during model binding. So something about the ProcessRequest implementation in the accepted answer was screwing up the normal model binding process, or at least the query string value provider.
This is a deal breaker, so I took a look at default MVC IHttpHandler (yay open source!): http://aspnetwebstack.codeplex.com/SourceControl/latest#src/System.Web.Mvc/MvcHandler.cs
I will not pretend that I grok'ed it in its entirety, but clearly, it's doing ALOT more in its implementation of ProcessRequest than what is going on in the accepted answer.
So, if all we really need to do is strip dashes from our incoming route data so that MVC can find our controllers/actions, why do we need to implement a whole stinking IHttpHandler? We don't! Simply rip out the dashes in the GetHttpHandler method of DashedRouteHandler and pass the requestContext along to the out of the box MvcHandler so it can do its 252 lines of magic, and your route handler doesn't have to return a second rate IHttpHandler.
tl:dr; - Here's what I did:
public class DashedRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
requestContext.RouteData.Values["action"] = requestContext.RouteData.GetRequiredString("action").Replace("-", "");
requestContext.RouteData.Values["controller"] = requestContext.RouteData.GetRequiredString("controller").Replace("-", "");
return new MvcHandler(requestContext);
}
}
