I would do this to make my email field unique
in the table.
$table->unique('email');
I've tried
public function up()
{
Schema::table('contacts', function(Blueprint $table)
{
$table->dropUnique('email');
});
}
Then, when I run php artisan migrate, I got this
It tell me that it's not there, but I'm 100% sure that it's there.
How do write a migration to undo that ?
You have to do $table->dropUnique('users_email_unique');
To drop an index you must specify the index's name. Laravel assigns a reasonable name to the indexes by default. Simply concatenate the table name, the names of the column in the index, and the index type.
This the better way to drop unique. You can use the real column name here.
$table->dropUnique(['email']);
