A "Device Template" is what defines a device, whereas a "Device" is a particular instance of a device installed in the home. So "Device Template" is the master record that everyone shares. For example, there will only be 1 Device Template for the "Sony XYZ-123" Television. You, and several others users may have this TV, and each of you will have your own "Device" that you give your own name, and which may have some settings of it's own. However, there is only 1 "Device Template" for that device.
Most users will never need to use the "Device Template" page unless they want to do development and make their own devices. If you do want to poke around in the Device Templates, be careful not to change anything unless you know what you are doing, since changing something here could cause your device to not function properly. All the settings for your device which you can change are set using the Wizard, or in the "My Devices" page.
Making Changes to Templates
If you make changes to the Device Template, this will affect your local system only. However, if you have fixed some errors, added functionality to an existing Device Template or created your own Device Template, you can use sqlCVS to merge those changes back into the master database so everyone can benefit from them. The same is true with everything in your local database--the user interface, even the online documentation you are reading now is editable. When you check-in changes using sqlCVS, sqlCVS will isolate those changes and notify the developer who is responsible for quality assurance for that section. Once the developer has confirmed the changes, he can have the changes merged back into LinuxMCE's main development database, which will eventually get propagated to the testing and release databases if the changes pass the tests.
Merging Template Changes
We recommend that you do merge any changes you make locally to the Device Templates because if you do not, then sqlCVS will not update that Device Template with any changes that may have been made to the master database. Your local copy will then likely become out of date. Note that sqlCVS will notify you when it does an update if you have changed a Device Template that was also changed in the master database. You will have the option of over-writing your local Device Template with the master one, or keeping your modified local copy.
Using Device Template Page
- Select the manufacturer and the device category and click "Apply filter" to restrict the device templates list to those from the device category and manufacturer selected.
- Click "Autofilter" to make this operation to be performed automatically every time the device category or manufacturer is changed.
- If you know the device template number, just type it in "device template" box.
