Module Installer Script not working

Question

Trying to create a custom module with an installer script, I followed this tutorial (with a few edits): http://inchoo.net/magento/magento-install-install-upgrade-data-and-data-upgrade-scripts/

I've tried running the code and it doesn't work :(

here's my config.xml:

Answer 1

I think you missed a folder inside sql.

You have to create a folder named namepsace_module_setup and then place all your script inside this folder.

So your sql folder structure will be:

   sql
     |_ namepsace_module_setup
            |_ your script files

Also, if you find namespace_module_setup in your core_resource table then you will have to remove this, so that your code runs again.

Hope this helps.
