As Joe states there is no 'current' portal when installing a module - but if you 'just' need a valid portal id you can fetch the first available. Fill in the rest of the fields as needed - and remember to take the database scheme into consideration (the curly brackets part).

INSERT INTO {YourDatabase}.{dbo}.[PortalSettings]

           ([PortalID]

           ,[SettingName]

           ,[SettingValue]

           ,[CreatedByUserID]

           ,[CreatedOnDate]

           ,[LastModifiedByUserID]

           ,[LastModifiedOnDate]

           ,[CultureCode]

           ,[IsSecure])

     VALUES

           ((SELECT TOP (1) [PortalID] FROM {YourDatabase}.{dbo}.[Portals] ORDER BY [PortalID])

           ,@SettingName, nvarchar(50),

           ,@SettingValue, nvarchar(max),

           ,@CreatedByUserID, int,

           ,@CreatedOnDate, datetime,

           ,@LastModifiedByUserID, int,

           ,@LastModifiedOnDate, datetime,

           ,@CultureCode, nvarchar(10),

           ,@IsSecure, bit,)
 

Hi Joe,

thanks for the answer. I wanted to give an initialize value to a portalsettings for my module, but, if I have no references to the current Portal, I can do what DnnBro suggested.

Thanks.

I would just do something like

// This is pseudocode, not c#!
protected string DefaultValueForMyModule {
   get {
      object o = PortalController.GetPortalSetting(PortalId, "DefaultValueForMyModule");
      if (o == null) {
         return "DefaultValue";
      }
      return o.ToString();
   }
}

Happy DNNing!
Michael

You can use a technique like this:

You should just be aware that DNN instances that contain thousands of portals exist.  Anytime this is the case, such a technique might not be the best way to do this.
