Make database changes | |
The first step in creating a migration is to make any schema changes to the database. If the changes are to the data only you can skip this step. | |
Create migration file | |
Next we create a migration file with the differences between the current app/Config/Schema/schema.php file and the database. To do this execute the Console/cake Migrations.migration generate command with the following options: | |
Do you want compare the schema.php file to the database? - y | |
Do you want to preview the file before generation? - n | |
Please enter the descriptive name of the migration to generate: - Name of migration | |
Do you want update the schema.php file? - y | |
Schema file exists. Would you like to do? (o/s/q) - o | |
Now we have a migration file to update our database schema and an up to date schema.php file. Open the new migration file and add a description of the migration to the $description variable. |
