laravel 8 迁移删除 worldcities 表

Question

I have a table called worldcities that has all the cities on this pl.net, but everytime I migrate:fresh --seed then all tables are deleted including this one. Also, it takes forever to put the cities back since it's about 1gb.

What would be the best way to use php artisan migrate:fresh --seed without also deleting the worldcities table? I have tried many options, but none is working yet.

I read something about --ignore=worldcities, but that doesn't work with fresh. So it's not taking me anywhere this far.

Answer 1

Instead of using migrate:fresh you can use migrate:refresh , which uses down() method of the migration.

So in down method comment dropping table: Schema::dropIfExists() ,

Then in up method, check that table is already exists or not:

if (Schema::hasTable('table_name')) {
    return;
}

For seeding simply check that record exists or not, for preventing duplication. Or for fewer query, just create if table doesn't have any records.
