3 Table Laravel Migration need advice - laravel

I think I am doing this correctly. I have a users, profile, and application table. Below are the migrations. I think I am linking them correctly in the migration but need advice to make sure. 1 user can have 1 profile but many applications.
User Table
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
Profile Table
public function up()
{
Schema::create('profile', function (Blueprint $table) {
$table->id();
$table->integer('user_id')->unsigned();
$table->string('address')->nullable();
$table->string('apt')->nullable();
$table->string('city')->nullable();
$table->string('state')->nullable();
$table->string('zipcode')->nullable();
$table->string('homephone')->nullable();
$table->string('mobile')->nullable();
$table->string('occupation')->nullable();
$table->boolean('over18')->nullable();
$table->string('homechurch')->nullable();
$table->string('homechurchcity')->nullable();
$table->string('pastor')->nullable();
$table->string('howoftenattend')->nullable();
$table->timestamps();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
});
Application
public function up()
{
Schema::create('pilgrim_application', function (Blueprint $table) {
$table->id();
$table->string('besttimetocall');
$table->string('nickname');
$table->foreignId('user_id')->constrained('users')->onDelete('cascade');
$table->foreignId('profile_id')->constrained('profile')->onDelete('cascade');
$table->timestamps();
});

Does your migration work at the moment?
First check your migration file order, for example
0000_user
0001_profile
1000_ pilgrim_application
1001_app_two
in case of multiple applications you could begin the migration with a different number for grouping files in a list, this can be handy if you want to create multiple applications.
Also, is it necessary to specify the relations user and profile in the pilgrim_application migration?
Through relationships in your models you can also access the pilgrim_application from the user model and vice versa.
$user->profile->pilgrim_application

Laravel Nova 2 models in 1 resource

In my case i have a User
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('address_id')->nullable();
$table->foreign('address_id')->references('id')->on('addresses');
$table->string('first_name');
$table->string('insertion')->nullable();
$table->string('last_name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->string('phone_number');
$table->string('avatar')->nullable();
$table->rememberToken();
$table->timestamps();
$table->softDeletes();
});
And i have a Address
Schema::create('addresses', function (Blueprint $table) {
$table->increments('id');
$table->string('city');
$table->string('street');
$table->string('zip_code');
$table->string('state');
$table->string('house_number');
$table->timestamps();
});
Is it possible to create a new user and add a address to it in the same Nova User Resource?
What can we add in the fields function of the Resource?
Do i need to overwrite the default create method? Or can this be fixed with a belongsTo ?
Currently i got it to work with using
morhpOne
method but this is not what i want. I first have to create a User and after that i can add an Address.
This should be simple, in your Nova User model add
BelongsTo::make('Address');
The Address field should represent the function in your User model that returns the Address relation
So in your user there should be
public function address()
{
return $this->belongsTo(Address::class);
}
I hope that that is what you are looking for, I will be happy to update my answer if given more information.

Laravel combine multiple collections into one query

I'm wondering if this is possible. I have 3 models.
Users
TenantPreferances
PropertyAdverts
I'm trying to find out if I can do a query like so.
Find all tenants, whose preferences, match the currently signed in users properties.
The 3 databases are like so
User Model
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('userType');
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
PropertyAdverts
Schema::create('property_adverts', function (Blueprint $table) {
$table->increments('id');
$table->string("photo");
$table->string('address');
$table->string('county');
$table->string('town');
$table->string('type');
$table->string('rent');
$table->string('date');
$table->string('bedrooms');
$table->string('bathrooms');
$table->string('furnished');
$table->longText('description');
$table->integer('user_id'); //Landlord ID
$table->timestamps();
});
Tenant Preferances
Schema::create('tenant_preferances', function (Blueprint $table) {
$table->increments('id');
$table->string('county');
$table->string('type');
$table->string('rent');
$table->string('bedrooms');
$table->string('bathrooms');
$table->boolean('status')->default('0');
$table->integer('user_id'); //Tenant ID
$table->timestamps();
});
Yes, that is possible. You need to dig in on relations. You can then create a function to define the relation on you model:
function propertyAdverts() {
return $this->hasMany(PropertyAdverts::class);
}
You can access the relation from the user model by using $user->propertyAdverts. If you want to eager load them you can do so:
User::with('propertyAdverts')->find(3);
But notice that Laravel does not do a regular join by default. It first fetches all users, and then fetches all propertyAdverts using a single query using a in statement.

Has Many Through where the middle table has both forain keys in laravel 5.6

I need to make a HasManyThough relation where the middle Model holds the foreign keys of both Models.
Here is detail:
Migrations:
Schema::create('carriers', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
});
Schema::create('shipping_zones', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
});
Schema::create('shipping_rates', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->integer('shipping_zone_id')->unsigned()->index();
$table->integer('carrier_id')->unsigned()->index();
$table->decimal('rate', 20, 6);
});
Now I need something like
$carrier->shippingZone()
Is there any easy way to get this?
As per your migrations you need Many To Many relation rather than the HasManyThough relation.
Carrier.php
public function shippingZones()
{
return $this->belongsToMany('App\ShippingZone', 'shipping_rates);
}
You can access all shipping zones related to the carrier using, $carrier->shippingZones.
If you need to chain the query you can use $shippingZones = $carrier->shippingZones()->orderBy('id')->get(); here
If you need to use HasManyThough you would have to change the migrations. here

Additional fields on polymorphic many to many table map to Eloquent model

I'm trying to create a ploymorphic many-to-many relationship that also includes an additional relationship. I can't seem to figure out how to get Eloquent to map the additional field to a model.
I have projects, users on those projects, and project roles that dictate permissions for that user on the project.
My tables:
Schema::create('projects', function(Blueprint $table){
$table->increments('id');
$table->timestamps();
$table->softDeletes();
$table->string('name');
$table->integer('possessor_id');
$table->string('possessor_type');
});
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->softDeletes();
$table->string('email');
$table->string('name');
$table->string('username');
});
Schema::create('project_accessors', function(Blueprint $table){
$table->increments('id');
$table->timestamps();
$table->integer('project_id')->unsigned();
$table->foreign('project_id')->references('id')->on('projects');
$table->integer('project_role_id')->unsigned();
$table->foreign('project_role_id')->references('id')->on('project_roles');
$table->integer('entity_id')->unsigned();
$table->string('entity_type');
});
Schema::create('project_roles', function(Blueprint $table){
$table->increments('id');
$table->timestamps();
$table->softDeletes();
$table->string('name');
$table->string('permissions');
$table->integer('project_id')->unsigned();
$table->foreign('project_id')->references('id')->on('projects')->onDelete('cascade');
});
I define projects on users like this:
public function projects()
{
return $this->morphToMany('App\Project', 'entity', 'project_accessors')->withTimestamps()->withPivot('project_role_id');
}
I define users and roles on projects like this:
public function roles()
{
return $this->hasMany('App\ProjectRole');
}
public function users()
{
return $this->morphedByMany('App\User', 'entity', 'project_accessors')->withTimestamps()->withPivot('project_role_id');
}
Is there a way to map project_role_id to an actual instance of my Project Role model?

Review Schedule Task Code In Laravel 5.1

I am writing a code to be scheduled to run occasionally. I want to remove records of users who have their details on the users table but does not have their records in the profiles table as well. I am thinking about removing the by their id, but I am not sure how I can make the match. profiles migration:
public function up()
{
Schema::create('profiles', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->string('gender',5);
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade'); // When a profile is deleted- his corresponding associated id details are deleted as well.
$table->tinyInteger('age')->unsigned()->nullable();
$table->string('goals')->nullable();;
$table->string('activityType')->nullable();
$table->rememberToken(); // for remember me feature.
});
}
Users migration:
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('username',20)->unique();
$table->string('email')->unique();
$table->string('password', 60);
$table->rememberToken();
$table->timestamps();
});
I have started to write the query, yet I am not sure how to proceed.
public function handle()
{
// type the query to get users that have no data in their profiles.
$empty_profile=App\Profile:::where('id','')->get;
$user_id=App\User::where('id')
}
Appreciate your help. Thanks.
Although your example is not exactly clear to me (and I wonder why there would be users without profiles in the first place?) I think this is what you need:
public function handle()
{
$empty_profiles = App\User::doesntHave('profile')->delete();
}
This will work if the models are correctly connected see also:
