You have to make the relation in your database. You can do it by adding this to your image migration:

$table->foreign('product_id')->references('id')->on('product');

laravel eloquent relation one to many returns null, In order to match up the eager loaded Product s with the Incoming_good s, Laravel needs the foreign key to be selected. Since you did not� One To Many. A one-to-many relationship is used to define relationships where a single model owns any amount of other models. For example, a blog post may have an infinite number of comments. Like all other Eloquent relationships, one-to-many relationships are defined by placing a function on your Eloquent model:

I assume your model names are Product and Image.

Please check whether below change will give you what you want...

return $this->hasMany('App\Image');

note that model name starts with uppercase letter and,

return $this->belongsTo('App\Product');

and database constraint as @steve-trap mentioned is not necessary. Anyway it will introduce a constraint so that you cannot add image for non-existing product.

Then in controller:

foreach (App\Product::find($product->id)->images as $image) {
    $arr[] = $image->image;
}

[Solved] HasMany relationship returns null, [Solved] HasMany relationship returns null. Posted 2 years ago by rsm23. I've a relationship between two tables : chapters and modules and here they are : One to Many Relationship Returning NULL When Queried Posted 4 years ago by cbuchert I'm working on my first project in Laravel and am having trouble getting a one to many relationship to pull data.

I solved this problem by:

  1. Changed the model names to uppercase.
  2. Changed the product table column name images to cover.
  3. Changed the method images() to pictures in Product Model

Conclusion: If you use the column name then don't use that column name for building relationship. and always write model name that starts with uppercase.

hasMany returning null and the query is wrong, I wouldn't be surprised if it's because you're using underscores in relationship names. I bet Eloquent doesn't expect that. It's best practice to use camelCase.
