我为什么不能在Laravel迁移

Question

Migration files in laravel is used to create the tables in the database, right? But when ever I try to migrate it gives me this error:

C:\\xampp\\htdocs\\app>php artisan migrate

[Illuminate\\Database\\QueryException] SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' already exists (SQL: create table users ( id int unsigned not null auto_increment primary key, name varchar(255) not null, email varchar(255) not null, password varchar(255) not null, remember_token varchar(100) null, created_at timestamp null, updated_at tim estamp null) default character set utf8mb4 collate utf8mb4_unicode_ci)

[PDOException] SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' already exists

---

and I created a new migration file and it's called test. I know users already exist but I want create the new table I created which is called test.

here is the migration file i am going to use to create my table but wont create:

    <?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateTestsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('tests', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('tests');
    }
}

here is the users migration file that tells me it exist:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

here is the password migration file:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreatePasswordResetsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('password_resets', function (Blueprint $table) {
            $table->string('email')->index();
            $table->string('token');
            $table->timestamp('created_at')->nullable();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('password_resets');
    }
}

here is the dummies migration file i have that i didn't talk about because i thought it is not the problem:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateDummiesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('dummies', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->text('body');
            $table->timestamp('date'); //if you dont put name for the timestamp it will create: create_at and update_at fields.
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('dummies');
    }
}

and sorry for keeping you guys waiting it took me long to find the edit button and fix the spacing of my code. It is my first time using stack over flow.

Answer 1

The migrations table in your database is out of sync with the rest of your database. Laravel is trying to re-run a migration to create the users table and failing.

If this is an entirely new project, you could delete all tables from your database and re-run all migrations. Alternatively, fix your migration table so that it accurately reflects the state of your database.

Answer 2

In your laravel/app/providers/AppServiceProvider.php add the following code inside boot

Schema::defaultStringLength(191);

Then try php artisan migrate:refresh

or best

drop all tables and run php artisan migrate again

Answer 3

Add following code in the start of your up function() of all tables

public function up()
{
        // Add this line
        Schema::dropIfExists('users');
        // from you down method
        Schema::create('users', function (Blueprint $table) {
            ...........
        });
}

Answer 4

Try this...

*// AppServiceProvider.php

use Illuminate\Support\Facades\Schema;

function boot()
{
    Schema::defaultStringLength(191);
}
