This means that when you are migrating, you are creating a foreign key constraint and those constraints are not meeting their conditions. To get around this, make sure the table you're making a relationship with exists when the foreign key is made, or make all your foreign keys last, after all other migrations.

If this is a live data migration, you need to first create the column that the foreign key will be on, then fix the data to fall within those constraints, then make the foreign key.

Ok will check if the order is appropriate in my migrations and seeds files.

I still get the error. Here are my seeds files: http://laravel.io/bin/R6KGM . Is there something wrong?
