deims-ntl-custom

Customizations for the NTL DEIMS migration

This is a set of custom Drupal 7.x modules. The ntl module extends the Drupal contributed migrate module and the DEIMS custom module D6 Migrate module, which in itself is an extension of the Drupal contrib. migrate. The ntl module addresses special customizations of the North Temperate Lakes LTER information management system

Instructions

Clone

• git clone --branch 7.x-1.x [email protected]:lter/deims-ntl-custom.git into a place of your choice (current directory, Desktop, etc)

Or download this module from:

• https://github.com/lter/deims-ntl-custom/archive/7.x-1.x.zip Extract the contents in a local directory, you will copy the parts inside to different places in your DEIMS install, as we explain now.

Once you have the repository locally, create a folder named modules under your DEIMS root sites/default (unless you have already made it)

Under the sites/default/modules, create another folder named ntl

Copy the ntl.* files you downloaded from github locally, into the ntl folder you just created. Also, copy the migration subfolder you downloaded from github into the same ntl folder. One more thing: To complete the migration-related toolkit, we will need to overwrite the parent DeimsContentDataSet Migration class. Please take the file migration-core/DeimsContentDataSet.php, and use it to replace the file with the same nane in profile/deims/modules/custom/deims_d6_migration/migration. This will ensure the parent class calls the correct Person class and a proper migration.

Also, we need new content types, views and DEIMS content type extensions for the NTL. You will find those, featurized, in the local github download subfolder named features . Inside, you will see some features that start with the word deims and some that begin with the word ntl. THe deims are overrides of existing features, and are located in /profiles/deims/modules/features, just place the content accordingly, overwrite the existing ones with the new - DEIMS will enact the changes. THe custom, ntl specific need to be moved too, for example, copy them in the modules folder, like this:

• cp -r deims-ntl-custom/features/ntl_* DEIMSROOT/sites/default/modules/

One more thing -- NTL uses the "content profile" in the Source D6 instance, which invalidates the default Person migration due to a messy database. To overcome that, we have to overwrite the parent DeimsContentPerson class. PLease copy the file at migration-core into the custom deims migration. Like this:

• `cp deims-ntl-custom/migration-core/DeimsContentDataSet.php --

• DEIMSROOT/profiles/deims/modules/custom/deims_d6_migration/migration`
  

Now visit the "migrate dashboard", if needed (like, nothing seems to change), Flush the Class Registry cache, (use the admin toolbar, or use "drush cc") and then, re-register the migration classes using the Migrate->Configuration page (admin toolbar, or from Migrate Dashboard). You should be ready to try the migration!
