This is the part 3 of 5 of my implementing of a MVC Browser history

MVC browser history – idea

Browser history –2 – implementing, small bugs

Browser history 3–trying to Nuget – modifications in order to can be transformed from an application to a component

Browser history 4–NuGet again – finally Nuget deployment

Browser history–part 5–conclusions – conclusions

TL;DR : Trying to add a feature (NuGET ) will conduce you to other features – apparently easy to implement – but took 2 hours…

Content:

First, source control is more important – http://www.joelonsoftware.com/articles/fog0000000043.html .I choose github  – deploy is a breeze with GitHub for windows . More, appharbor integration with github is awesome – you can see the application live at http://browserhistory.apphb.com/ .

Now , for generating Nuget package, I should be moving the classes on their own assembly / dll. Also , added this blog to the info. Ensure it works the same. Uploaded to GitHub

And appharbor just deployed

Now, it will be good if I let user switch implementation between memory saving  and database saving… in order to developers( that have installed the dll with  NuGet  ) switch easily to their database.

Created

BrowserUserHistoryRepositorySqlServer

and , after some implementing of IBrowserUserHistoryRepository , the method

public IBrowserUserHistoryRepository FilterByUser(string UserName)

put some problems – but solved with a private variable.

Now must decide the best way to switch between MemoryRepository and SqlServerRepository in

public static T AddOrRetrieveFromApplication<T>(HttpApplicationStateBase app)

where T:new()

First, we must retrieve at runtime the instance of the interface – so structuremap to the rescure.

Second, if we need to retrieve a class – must have at least a default constructor.

So the constraint of the T was gone away   – and the code is

T result;

if (typeof(T).IsInterface) {

result =(T) ObjectFactory.GetInstance(type) ;

}

else

{

result = (T)Activator.CreateInstance(type);

}

Also, in global.asax the following lines were added:

//ObjectFactory.Configure(ce => ce.For<IBrowserUserHistoryRepository>().Use<BrowserUserHistoryRepositoryMemory>());             //uncomment those for sql server ce             ObjectFactory.Configure(ce => ce.For<IBrowserUserHistoryRepository>().Use<BrowserUserHistoryRepositorySqlServer>());

Now, when deploy , AppHarbor will NOT found EntityFramework dll.

Added HintPath to csproj to find EF

<HintPath>..\packages\EntityFramework.5.0.0\lib\net40\EntityFramework.dll</HintPath>

as seen at

http://blog.appharbor.com/2012/04/24/automatic-migrations-with-entity-framework-4-3

and it works!

More, it works with sql server AppHarbor addon  and transformation of web.config.

It took 2 hours to do this thing, apparently simple.

Now you can find the code source on github at https://github.com/ignatandrei/MVCbrowserHistory

You can browse the application at http://browserhistory.apphb.com/

Next time: (maybe some tests and ) NuGET!

This is the part 2 of 5 of my implementing of a MVC Browser history

MVC browser history – idea

Browser history 3–trying to Nuget – modifications in order to can be transformed from an application to a component

Browser history 4–NuGet again – finally Nuget deployment

Browser history–part 5–conclusions – conclusions

Now we repair the important issues and make some GUI adjustements to be nicer to the user GUI.

1. Why the history does not display?
   • Because OnResultExecuted  is executed AFTER the View that display the results  is executed
   • Fix: do not display the ones that have no title. Modified ViewModel to take an IEnumerable.
2. Why the count does not display after 2 clicks?
   • Because it was not saved in BrowserUserHistoryRepositoryMemory – only after SaveToRepositoryInterval links number
   • Fix: In the action save again to have latest clicks. Also modified interface Save to take an IEnumerable – and not a class.
3. Modified GUI interface to have links where the URL displays – add ViewUrl shared VIew in MVC.
4. Add numbering to the table ( 1,2,…)
5. Add texts ( instead of My MVC application – My Browser History application)
6. Add Filter By User – to be easier for the programmers that will use the program.
7. Maybe will be useful to add sorting and filtering   – but only if someone asks.
