Home CMS Documentation Home Cartella Developing Cartella Custom Objects Adding Fields to Custom Objects

Adding Fields to Custom Objects

You can modify custom objects after implementation by completing each of the following procedures:

Add fields to the new object within the Cartella UI.
Edit form definition fields within Microsoft SQL Server Management Studio (SSMS).
Update [Site_Root]\App_Code\[Custom_Object_Name].cs.

Warning

Do not edit the SQL scripts that were generated by Object Builder, as this may render your Cartella site inoperable.

Adding Fields in UI

To add fields to the new object in the Cartella UI:

Log in to Cartella.
Navigate to Settings > Customize > Manage Fields.
Select the custom object from the Field Management drop-down list.
Click Add Fields.
At the bottom of the Fields list, enter values for Name, Unique ID, and Field Type.
If the new field is required, enable the Required option.
Click Save.

Editing Form Definition Fields in SSMS

To edit form definition fields:

Open the Cartella database in Microsoft SQL Server Management Studio (SSMS).
In SSMS, navigate to the dbo.Table_EditFormDefinition_Fields table within your Cartella database.
Right click the dbo.Table_EditFormDefinition_Fields table, then select Edit Top 200 Rows.
Scroll to the end of the table and provide values for the new field, manually.
Close SSMS.

Updating Custom Object Controller in App_Code

To update the object's controller:

Navigate to [Site_Root]\App_Code.
Open [Custom_Object_Name].cs in Visual Studio or other ASP.NET editor.

In the custom object's controller, update the code to include the new property.

In CustomModule1.cs, each code block needing an update is called out in a comment, where Field2 is the new property.
