How to change enum type column in laravel migration?

Question

I am using Laravel 5.1 and I have a table called packages with this structure:

id              int(11)
weight          decimal(10,2)           
weight_unit     e         


        

Answer 1

In case you dont want to lose your data and update it with the new values I came up with this solution:

// Include old and new enum values
DB::statement("ALTER TABLE packages MODIFY COLUMN weight_unit ENUM('Kg.', 'Gm.', 'Grams', 'Kgs', 'Pounds')");
// Replace Kg. with Kgs
Packages::where('weight_unit', 'Kg.')->update(['weight_unit' => 'Kgs']);
// Replace Gm. with Grams
Packages::where('weight_unit', 'Gm.')->update(['weight_unit' => 'Grams']);
// Delete old values
DB::statement("ALTER TABLE packages MODIFY COLUMN weight_unit ENUM('Grams', 'Kgs', 'Pounds')");

This way you can replace your old values with the new ones.
