创建具有多个地区和行业之间关系的记录

Question

im having a error with my app, it looks averything fine, but is creating a wrong query, but i have my tables and models right, basically i have a registration of a user that can select more than one regions and industry/area. My error is:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'hjobs.region_user' doesn't exist (SQL: select `region_id` from `region_user` where `user_id` is null)

Model User:

public function regionsToWork(){

        return $this->belongsToMany(Region::class);
    }

    public function industriesToWork(){
        return $this->belongsToMany(Industry::class);
    }

AuthController:

 $user = new User();
 $user->name = $data['name'];
   ...

 $user->regionsToWork()->sync($data['region'], false);
 $user->industriesToWork()->sync($data['industry'], false);
 $user->save();

Tables DB: USER: 

    -id; 
    -email 
    ...

user_industry:

id;
user_id;
industry_id;
user_region:

id;
user_id;
region_id;

Answer 1

It looks like the pivot table name is different than what it's expecting, region_user as opposed to user_region.

You can manually specify the pivot table name in your belongsToMany method like this:

return $this->belongsToMany(Region::class, 'user_region');
