_DB Migrate

When CT has been updated to a never version then there may also been an update in the Mysql database. You then have the option to migare the DB structure changes with the terminal commands bellow.

Can be used for DB creation and migration. Version stepping is being implemented.

Migrate using:

• Control Tower
• Terminal

Control Tower: Migrate

Migrations

Open the migration window under you profile image at the top right side. You need to have Super Admin permissions to have access.

You can either migrate a table in the database or just create a backup. If you choose to migrate then a backup will also automatically be created. If you check the checkbox "Läsa" then te migration will generate as SQL code but will not try to migrate.

Backups

Here you can load or remove backups

Terminal: Migrate

If you for some reason can not access the migrations within Control Tower then you also have the option to migrate with with ssh/terminal. You also have some more options here.

CD

cd ct-admin/includes/

You an also be create migrations or just manage the database with PHP

// USAGE:

// Init class
// Arg1: Table name
$mig = new \query\create("test");

// Rename: IF table name is "test" or "test1" then it will be renamed to "test2".
// Has to be the first method to be called
//$mig->rename(["test1", "test2"]);

// Will create new stuff and alter current stuff
$mig->auto();

// Only create table
//$mig->alter();

// Only alter table
//$mig->alter();

// Only drop table
//$mig->drop();

// Add/alter columns
$result = $mig->column("id", [
    "type" => "int",
    "length" => 11,
    "attr" => "unsigned",
    "index" => "primary",
    "ai" => true

])->column("testKey", [
    // Drop: Will drop the column
    "drop" => true,
    "type" => "int",
    "length" => 11,
    "index" => "index",
    "attr" => "unsigned",
    "default" => "0"

])->column("name", [
    "type" => "varchar",
    "length" => 200,
    "collate" => true,
    "default" => ""

])->column("loremname_1", [
    // Rename: IF old column name is "loremname_1 (se one row above)" or "loremname_2" then it will be renamed to "permalink"
    "rename" => ["loremname_2", "permalink"],
    "type" => "varchar",
    "index" => "index",
    "length" => 200,
    "collate" => true

]);

// Will execute migration
$mig->execute();

// Get executed rows as SQL string that can be used manually 
// Can be called before execute has even been triggered
print_r($mig->build());
