magento install script 1.8.1 - magento

Question

I'm trying to create a symply module for import country region and more in database.It's very simple but the data wasn't import.I can't figure why:
config.xml
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<Province_Italian>
<version>1.0.50</version>
</Province_Italian>
</modules>
<global>
<resources>
<province_italian_setup>
<setup>
<module>Province_Italian</module>
<class>Province_Italian_Model_Resource_Setup</class>
</setup>
<connection>
<use>core_setup</use>
</connection>
</province_italian_setup>
<province_italian_write>
<connection>
<use>core_write</use>
</connection>
</province_italian_write>
<province_italian_read>
<connection>
<use>core_read</use>
</connection>
</province_italian_read>
</resources>
</global>
</config>
basic configuration file
and i had this folder structure with install script
Province/Italian/Model/Resource/Setup.php
data/province_italian_setup/data-install-x.x.x.php
and usually file in etc folder for configurazion config.xml
It' very simple ,the module is added because i've seen this reference in core_resource table, but seem that can't read installation file from data folder.
Where's mistake?
I'm going mad!
Thanks

Answer 1

"because i've seen this reference in core_resource"
Dalete that reference record from core_resource, delete cache, and try again

Answer 2

A couple of suggestions:
Make sure that have your module enabled, by having a file in app/etc/modules/Province_Italian.xml stating the following information:
<?xml version="1.0"?>
<config>
<modules>
<Province_Italian>
<active>true</active>
<codePool>local</codePool>
<depends><!-- Put your Module dependencies here --></depends>
</Province_Italian>
</modules>
</config>
The code of the module can be found in app/code/local/Province_Italian
The first install file matches the version number of the module. In this case that would be 1.0.50. So the filename must be
app/code/local/Province_Italian/data/province_italian_setup/data-install-10.0.50.php
Once the install script has ran, it cannot run again. Make sure that the code province_italian_setup is absent in the database table core_resource. This will trigger Magento to run the setup script.
Have logging (Mage::log(...)) in your datat install script to see it the script runs.
When you have no custom setup functionality, then the Province_Italian_Model_Resource_Setup.
I also noticed that the models is missing in your XML. Probably your need to add it. Based upon your description, you probably need (1) a model to to manipulate a datastore purely through PHP code, and (2) need a resource model to import the data into a custom database table.
<config>
<modules>
<Province_Italian>
<version>1.0.50</version>
</Province_Italian>
</modules>
<global>
<models>
<province_italian>
<class>Province_Italian_Model</class>
<resourceModel>province_italian_resource</resourceModel>
</province_italian>
<province_italian_resource>
<class>Province_Italian_Model_Resource</class>
<entities>
<!-- Put your entities here -->
</entities>
</province_italian_resource>
</models>
<resources>
<province_italian_setup>
<setup>
<module>Province_Italian</module>
<!-- <class>Province_Italian_Model_Resource_Setup</class> -->
</setup>
</province_italian_setup>
<province_italian_write>
<connection>
<use>core_write</use>
</connection>
</province_italian_write>
<province_italian_read>
<connection>
<use>core_read</use>
</connection>
</province_italian_read>
</resources>
</global>
I hope the above will help.
