Build MVC Applications with Connectivity to Sage 50 UK Data

This article shows how to use only the Entity Framework and the CData ADO.NET provider to access Sage 50 UK from an ASP.NET MVC application.

This article shows how to use wizards in Visual Studio to drop the CData ADO.NET Provider for Sage 50 UK into a simple MVC (model, view, controller) project.

Create the Entity Framework Model

Follow the steps below to save connection properties and map tables to entities in the data model.

  1. Create a new MVC project in Visual Studio. In this example, the project name is MvcSage50UKApp.
  2. If you are using Entity Framework 6, you will need to take the preliminary step of registering the Sage 50 UK Entity Framework provider for your project. See the "LINQ and Entity Framework" chapter in the help documentation for a guide.

    Note that MVC 3 scaffolding and MVC 4 scaffolding do not support Entity Framework 6. You can use your scaffolding with Entity Framework 6 by upgrading to the latest version of MVC.

  3. To add the .edmx file from the designer, right-click your Models folder and click Add New Item. Select ADO.NET Entity Data Model, name the model, and click Add. In this example, the name of the model is Sage50UKModel.
  4. In the Entity Data Model wizard, select the option 'EF Designer from database'. The Entity Data Model wizard is displayed.
  5. Click New Connection. Select CData Sage 50 UK Data Source in the dialog that is displayed.
  6. Specify the required connection string properties.

    Note: Only Sage 50 UK 2012 and above are supported.

    The User and Password properties, under the Connection section, must be set to valid Sage 50 UK user credentials. These values will be the same used to log in to the Sage 50 UK software.

    Additionally, the URL property, under the Connection section, will need to be set to the address of the company dataset desired. To obtain the address, do the following:

    1. If you have not already done so, open the Sage 50 UK software.
    2. Click Tools -> Internet Options.
    3. Select the SData Settings tab.
    4. Click the Details button next to Sage 50 Accounts. A window is displayed containing a list of company names along with the address to their corresponding datasets.
    5. Set the URL property to the value in the address field next to the company desired.

    A typical connection string is below:

    URL=http://your-server:5493/sdata/accounts50/GCRM/your-address;User=Manager;
  7. Name the connection and select whether to include sensitive information, such as connection credentials, in the connection string. For simplicity, this example saves sensitive information in Web.config. The connection settings are saved as Sage50UKEntities.

  8. Select the tables and views you need. In this example, TradingAccounts is imported. Also, the option to pluralize object names is deselected in this example. Click Finish to create the .edmx file.
  9. Build your project to complete this step.

Scaffold the Controller and Views

After creating the model and building the project, you can use ASP.NET Scaffolding wizards to create the controller and the views.

  1. In Solution Explorer, right-click the controllers folder and click Add -> Controller. Select MVC 5 Controller with views, using Entity Framework.
  2. In the Add Controller dialog that is then displayed, select the following options:

    • Model class: Select a table you imported; for example, TradingAccounts.
    • Data context class: Select your context class.
  3. Leave the default values for the other fields.

You can now access the list of TradingAccounts records at http://MySite/TradingAccounts. Next to each record are links to edit, delete, and see more information. You can also create new TradingAccounts records. With every state change the site picks up any data changes.
