Undefined table: 7 ERROR: relation "expenses" does not exist - php

Question

Since i am a spanish speaker, i wrote the controllers and models of income and expense in spanish; while all the rest were on english..
I renamed and changed manually Routes, Controllers, Migrations and even Models.
And when i run php artisan migrate:reset this is my error.
Undefined table: 7 ERROR: relation "expenses" does not exist (SQL: alter table "expenses" drop column "location_id")**
I use psgql and laravel 5.3
This is my code:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Expense extends Model
{
protected $fillable = ['id', 'description', 'quantity'];
public function locations()
{
return $this->hasMany('App\Location');
}
public function icons()
{
return $this->hasMany('App\Icon');
}
public function types()
{
return $this->hasMany('App\Type');
}
public function stores()
{
return $this->hasMany('App\Store');
}
}
Migration:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateExpensesTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('expenses', function (Blueprint $table) {
$table->increments('id');
$table->float('quantity');
$table->string('description');
$table->integer('location_id')->unsigned();
$table->integer('icon_id')->unsigned();
$table->integer('type_id')->unsigned();
$table->integer('store_id')->unsigned();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('expenses');
}
}
Location Migration:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateLocationsTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('locations', function (Blueprint $table) {
$table->increments('id');
$table->string('address');
$table->float('lat');
$table->float('long');
$table->integer('store_id')->unsigned();
$table->timestamps();
$table->foreign('store_id')->references('id')->on('stores')->onDelete('cascade');
});
Schema::table('expenses', function (Blueprint $table) {
$table->foreign('location_id')->references('id')->on('locations')->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::table('expenses', function (Blueprint $table) {
$table->dropColumn('location_id');
});
Schema::dropIfExists('locations');
}
}
Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Location extends Model
{
protected $fillable = ['id', 'address', 'lat', 'long'];
public function expenses()
{
return $this->belongsTo('App\Expense');
}
public function stores()
{
return $this->hasOne('App\Store');
}
}
Hope you can help me.

Answer 1

When it says
relation "expenses" does not exist
It usually happens when your expenses table must have been dropped before migration:reset rolled back CreateLocationsTable.
Check the order of execution of your migrations.
As you were trying to reset, to fix it now, open your database, drop all tables manually and execute migrate again.

Answer 2

Schema::table('expenses', function (Blueprint $table) {
$table->foreign('location_id')->references('id')->on('locations')->onDelete('cascade');
});
change this to
Schema::alter('expenses', function (Blueprint $table) {
$table->foreign('location_id')->references('id')->on('locations')->onDelete('cascade');
});

I had this error. I had to resolve it by adding the prefix of the database to my model. There is a way to change this in the database, and it is supposed to be changed. it's something, like $user, public. It's the schema profile. Mine is changed when I login, but for some reason the model is not binding to schema. So I had to specify it in the model. Instead of
protected $table = 'table_name';
I had to do
protected $table = 'schema_name.table_name';
Note: By schema_name or table_name, I'm not referring for you to put schema_ then the name. That is just so it's easier to read.
The model is located in the model folder under the App/Models folder depending on which version of Laravel you using and how your Models are organized. If your model name is not the same as the table name, then you will need to put the protected $table. But if the schema is not there, then you will need to add that.
I do have this set in my DB_DATABASE_SECOND= in .env file. But it somehow still doesn't pick up the prefix.
But yeah. Pretty much I couldn't find the answer anywhere, but I

Solution found in:
Laravel assumes the database table is the plural form of the model name
https://laravel.com/docs/8.x/eloquent#table-names
you need to declare the singularity name of your table.
add this line
protected $table = 'expense'
at the end of your model file
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Expense extends Model
{
protected $fillable = ['id', 'description', 'quantity'];
public function locations()
{
return $this->hasMany('App\Location');
}
public function icons()
{
return $this->hasMany('App\Icon');
}
public function types()
{
return $this->hasMany('App\Type');
}
public function stores()
{
return $this->hasMany('App\Store');
}
protected $table = 'expense';
}
