Laravel BelongsToMany Error - Base table or view not found - laravel

Question

I hope this thread find everyone healthy.
What is wrong with the following code? I am getting an error on my many to many relationship. For the past 4 hours i am stuck with this problem. I would be very thankful if you find the bug or source of problem.
Here is my code and tables:
Schema::create('products', function(Blueprint $table)
{
$table->increments('id');
$table->integer('category');
$table->string('thumbnail');
$table->string('images');
$table->string('logo');
$table->string('main_photo');
$table->timestamps();
});
//categories table
Schema::create('product_categories', function(Blueprint $table)
{
$table->increments('id');
$table->string('category');
});
//relationship table
Schema::create('product_productcategory', function(Blueprint $table)
{
$table->increments('id');
$table->integer('product_id'); // the id of the bear
$table->integer('productcategories_id'); // the id of the picnic that this bear is at
});
products model:
class Product extends Model
{
protected $table = 'products';
public function product_category() {
return $this->belongsToMany('App\product_category', 'App\product_productcategory', 'product_id', 'productcategories_id');
}
}
And pivot model
class product_category extends Model
{
protected $table = 'product_categories';
public function product() {
return $this->belongsToMany('App\Product', 'App\product_productcategory', 'productcategories_id', 'product_id');
}
}
Thanks in advance!
Updates: The problem is solved thanks to #mimo.
But now i want to translate the categories in different languages so i created a table like this:
Schema::create('category_translations', function(Blueprint $table)
{
$table->increments('id');
$table->string('name');
$table->integer('category_id')->unsigned();
$table->foreign('category_id')->references('id')->on('product_categories')->onDelete('cascade');
$table->integer('locale_id')->unsigned();
$table->foreign('locale_id')->references('id')->on('locales')->onDelete('cascade');
$table->unique(['category_id', 'locale_id']);
});
And my product categories with new relationship to the translations
class product_category extends Model
{
protected $table = 'product_categories';
public function product() {
//return $this->belongsToMany('App\Product', 'App\product_productcategory', 'productcategories_id', 'product_id');
return $this->belongsToMany('App\Product', 'product_productcategory');
}
public function translation($lang) {
return $this->hasMany('App\Category_Translation')->where('locale_id', '=', $lang);
}
}
And in category translation:
class Category_Translation extends Model
{
protected $table = 'category_translations';
public function product_category() {
return $this->belongsTo('App\product_category');
}
}
And finally my Product:
class Product extends Model
{
protected $table = 'products';
public function translation($lang) {
return $this->hasMany('App\Product_Translation')->where('locale_id', '=', $lang);
}
public function product_category() {
//return $this->belongsToMany('App\product_category', 'App\product_productcategory', 'product_id', 'productcategories_id');
//return $this->belongsToMany('App\product_category', 'product_productcategory');
return $this->belongsToMany('App\product_category', 'product_productcategory')->translation(1);
}
}
Now when i run:
$product = App\Product::find(1)->first();
echo $product->product_category;
I get error:
Call to undefined method Illuminate\Database\Query\Builder::translation()

Your migration file is wrong:
//relationship table
Schema::create('product_productcategory', function(Blueprint $table)
{
$table->integer('product_id')->unsigned()->index(); // the id of the bear
$table->foreign('product_id')->references('id')->on('products');
$table->integer('productcategories_id')->unsigned()->index(); // the id of the picnic that this bear is at
$table->foreign('productcategories_id')->references('id')->on('product_categories');
});
This code will made the relationship on the database level.
When you have 12 min free time you can check out this tutorial about many to many relationships in laravel:
https://laracasts.com/series/laravel-5-fundamentals/episodes/21
Update:
you need to update your relationships too:
class Product extends Model
{
protected $table = 'products';
public function product_category() {
return $this->belongsToMany('App\product_category', 'product_productcategory');
}
}
and:
class product_category extends Model
{
protected $table = 'product_categories';
public function product() {
return $this->belongsToMany('App\Product', 'product_productcategory');
}
}
