jquery template - jumate de MVC

Nu odata am scris ceva asemanator cu aceste cond in jQuery:

var sablon = "<b> ${nume} </b>";
Problema la acest template este modul in care se poate manipula . In cazul in care dorim sa facem o modificare, suntem nevoiti sa cautam in cod unde avem definit template-ul si sa facem modificari pe el. In cazul in care un nou dezvoltator trebuie sa faca modificari, el o sa fie nevoit sa cauta in cod.

O solutie este sa folosim un template pentru acest lucru. Primul pas este sa definim template-ul in forma urmatoare:

<script id="numeTemplate" type="text/html">
<b> ${nume} </b>
Prin acest mod, o sa ne putem referi template-ul nostru in orice loc din cod pe baza unui ID, totodata o sa fie foarte usor de grupat toate template-urile.

Urmatorul pas este sa referim pe langa libraria de jquery si libraria pentru template-uri. Numele ei este: jquery.tmpl.js.

Template-ul pe care l-am definit mai sus trebuie putin modificat, forma sa trebuie sa fie:

<script id="numeTemplate" type="text/html">
<b> ${nume} </b>
JSON va scoate automat valoarea pentru nume prin ${}. Putem sa avem orice fel de conditii logice, in exemplul dat mai sus, avem un IF care afiseaza imagini diferite pentru barbati si femei. Prin acest mecanism putem sa cream template-uri complexe, in care logica care defineste modul in care se face randarea la anumite elemente din template sa fie in interiorul la template.
Datele pentru care facem randarea sunt:
var persoane = [
{ Nume = "Stefan", IsMan = 1},
{ Nume = "Oana", IsMan = 0},
{ Nume = "Mihai", IsMan = 1}
Pentru a putea folosi template-ul definit, putem sa folosim functiile
  • tmpl([data],[options])
  • $.tmpl(template,[data,[options])
Pentru exemplul dat mai sus ar trebuii sa scriem:
Unde listaPersoaneDiv reprezinta id la divul care afiseaza template-ul.
Si gata, in acest moment avem un template pe care il putem folosi in orice locatie. Putem sa privim totul ca o jumatate din MVC, doar partea de Model-View.
Pentru mai multe informatii:


  1. buna ziua

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

Run native .NET application in Docker (.NET Framework 4.6.2)

The main scope of this post is to see how we can run a legacy application written in .NET Framework in Docker.

First of all, let’s define what is a legacy application in our context. By a legacy application we understand an application that runs .NET Framework 3.5 or higher in a production environment where we don’t have any more the people or documentation that would help us to understand what is happening behind the scene.
In this scenarios, you might want to migrate the current solution from a standard environment to Docker. There are many advantages for such a migration, like:

Continuous DeploymentTestingIsolationSecurity at container levelVersioning ControlEnvironment Standardization
Until now, we didn’t had the possibility to run a .NET application in Docker. With .NET Core, there was support for .NET Core in Docker, but migration from a full .NET framework to .NET Core can be costly and even impossible. Not only because of lack of features, but also because once you…
