I have an employer_profiles table, a job_posts table and an employer_profile_job_post table. I'm trying to make a relationship and add the foreign keys but I keep getting this error and I'm not sure why.

When I migrate my DB, I got this error. Below is my coding:

$table->foreign('category_id')->references('id')->on('categories');
});
}

I am using Laravel 5.8 and package "goldspecdigital/laravel-eloquent-uuid" because I need to use UUID4 and here is my migration file:
public function up()
{
Schema::create('images', function (Blueprint $table) {
$table->bigIncrements('id');
// $table->timestamps();
$table->string('path');
$table->uuid('visit_id');
$table->foreign('visit_id')->references('id')->on('visits');
});
}
I get the following error:
SQLSTATE[HY000]: General error: 1005 Can't create table doctors
_pharmacy.images (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: alter table images
add constraint images_visit_id_foreign foreign key (visit_id) references visits (id))
How do I solve this?
Update the schema for visits and images as follows.
Then run php artisan migrate cmd.
visits table schema
public function up()
{
Schema::create('visits', function (Blueprint $table) {
$table->uuid('id')->primary();
// your column will be here
......
......
$table->timestamps();
});
}
images table schema
public function up()
{
Schema::create('images', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('path');
$table->uuid('visit_id');
$table->foreign('visit_id')->references('id')->on('visits');
});
}
am trying to do laravel migration but am getting this error
[Illuminate\Database\QueryException]

public function down(){

When you are creating a foreign key, the categories.id and posts.category_id must have the same type.
Swap the ->bigInteger() with ->integer()should solve your problem:
Your categories migration:
public function up(){
Schema::create('categories', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->timestamps();
});
}
public function down(){
Schema::drop('categories');
}
In your posts migration:
public function up(){
Schema::create('posts', function (Blueprint $table) {
$table->increments('id');
$table->integer('category_id', false, true);
//Or $table->unsignedInteger('category_id');
$table->foreign('category_id')
->references('id')
->on('categories');
$table->timestamps();
});
}
public function down(){
Schema::drop('posts');
}
Hope it helps.
Foreign key should always be of same type in both child and parent table.
In your case, categories.id is of type ٰINTEGER while posts.category_id is defined as BIGINT. Replacing your posts migration with below should work.
public function up() {
Schema::create('posts', function (Blueprint $table) {
$table->increments('id');
$table->integer('category_id')->unsigned();
$table->foreign('category_id')->references('id')->on('categories');
$table->timestamps();
});
}
I got this error when I change I to bigIncrements:
.`products` (errno: 150 "Foreign key constraint is incorrectly formed")
my code:
public function up()
{
Schema::create('products', function (Blueprint $table) {
$table->bigIncrements('id')->unsigned();
$table->string('title');
$table->integer('current_buy');
$table->integer('count');
$table->text('short_description');
$table->text('long_description');
$table->tinyInteger('status')->default(0);
$table->string('series');
$table->integer('max_buy');
$table->integer('parent_product_id')->nullable()->unsigned();
$table->foreign('parent_product_id')->references('id')->on('products')->onDelete('cascade');
$table->tinyInteger('admin_seen')->default(0);
$table->timestamps();
});
DB::update("ALTER TABLE products AUTO_INCREMENT = 1000;");
}
but below code works fine;
public function up()
{
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->integer('current_buy');
$table->integer('count');
$table->text('short_description');
$table->text('long_description');
$table->tinyInteger('status')->default(0);
$table->string('series');
$table->integer('max_buy');
$table->integer('parent_product_id')->nullable()->unsigned();
$table->foreign('parent_product_id')->references('id')->on('products')->onDelete('cascade');
$table->tinyInteger('admin_seen')->default(0);
$table->timestamps();
});
// DB::update("ALTER TABLE products AUTO_INCREMENT = 1000;");
}
Since you're using bigIncrements() for id, to make it work change this:
$table->integer('parent_product_id')->nullable()->unsigned();
to this:
$table->bigInteger('parent_product_id')->nullable()->unsigned();
