sqlstate 42s02 base table or view not found 1146 table code example
Example 1: SQLSTATE[42S02]: Base table or view not found: 1146 Tabl
It seems Laravel is trying to use category_posts table (because of many-to-many relationship). But you don't have this table, because you've created category_post table. Change name of the table to category_posts.
Example 2: Base table or view not found: 1146 Table
class Cotizacion extends Model{
public $table = "cotizacion";
