One to Many Relationship. Implementing --associate

''' Hi, I have, Tables: businesses briefcases So, a briefcase can have many business. Business Model:

  public function briefcase(): belongsTo
  {
      return $this->belongsTo(Briefcase::class);
  }

  public function briefcase(): belongsTo
  {
      return $this->belongsTo(Briefcase::class);
  }

Briefcase Model:

  public function businesses(): hasMany
  {
      return $this->hasMany(Business::class);
  }

  public function businesses(): hasMany
  {
      return $this->hasMany(Business::class);
  }

Relation Manager --associate:

php artisan make:filament-relation-manager BriefcaseResource businesses name --view --associate

php artisan make:filament-relation-manager BriefcaseResource businesses name --view --associate

When trying to associate a business I get:

Call to undefined method App\Models\Business::briefcases()

Call to undefined method App\Models\Business::briefcases()

Any suggestions? Thank you.

I think you need to define $inverseRelationship = 'business'; in this case

Hi Dennis, Thank you for time and advice. Your suggestion doesn't appear to solve my issue... Following Laravel naming conventions I named the inverse of the relationship:

public function businesses(): hasMany
  {
      return $this->hasMany(Business::class);
  }

public function businesses(): hasMany
  {
      return $this->hasMany(Business::class);
  }

I have renamed it to:

public function business(): hasMany
  {
      return $this->hasMany(Business::class);
  }

public function business(): hasMany
  {
      return $this->hasMany(Business::class);
  }

I have also regenerated...

php artisan make:filament-relation-manager BriefcaseResource business name --view --associate

php artisan make:filament-relation-manager BriefcaseResource business name --view --associate

No luck...

I am sorry. I meant briefcase and it belongs on the relation manager class

Hi, I think I don't get what you mean... You suggest I have to generate my BrifcaseResource relation manager as follows:

sail artisan make:filament-relation-manager BriefcaseResource briefcase name --associate

sail artisan make:filament-relation-manager BriefcaseResource briefcase name --associate

Thanks.

No, no need to generate something new. Just edit the relation manager file and add the property

Hey, Thank you! For the record... on my BriefcaseResource, RelationManagers, BusinessesRelationManager I added:

protected static ?string $inverseRelationship = 'briefcase';

protected static ?string $inverseRelationship = 'briefcase';

In the docs I found that $inverseRelationship should be used when "relationships with unconventional naming conventions". I don't see this is my case... If you have a minute, is briefcase/briefcases somehow not supported?

Dennis Koch•2y ago

And that still doesn’t work?

Pablo TorresOP•2y ago

Now It is works...! I should say thank you, now it works.

Nice. The default for RM is a belongsToMany/hasMany in both directions. That's why you need to add the inverseRelationship. Filament doesn't know about it from your models
