Laravel Migration table not created - php

I am a new learner of Laravel.And I follow the tutorial to create a articles table.Here's part of my code in /database/migrations/2017_02_13_145946_create_article_table.php
public function up()
{
//
Schema::create('articles', function(Blueprint $table)
{
$table->increments('id');
$table->string('title');
$table->text('body')->nullable();
$table->integer('user_id');
$table->timestamps();
});
}
When I run php artisan migrate the table was not created.I googled the problem and ran php artisan migrate:reset command to delete all the tables.When I ran php artisan migate command again.It shows
Migrated: 2014_10_12_000000_create_users_table
Migrated: 2014_10_12_100000_create_password_resets_table
Migrated: 2017_02_13_145946_create_article_table
But nothing was created but only updated the record of migrations table.The table user and password_resets was also not created.
Any ideas what I might be doing wrong?

It is because of Table column(values) length is by default 1071 which not accept by mysql
To clear this problem go to mysql and delete all the tables.
Go to your application(project) folder => app => Providers
write this on top of your AppServiceProvider.php file.
//edit:yrs:- Needed for edit
use Illuminate\Support\Facades\Schema;
write this inside the boot method
//edit:yrs:-we can edit column sizefor tables here
Schema::defaultStringLength(150);
then come to console and execute the
*command />php artisan migrate:status and see the run status is y or n if it is n then execute
*command />`php artisan migrate`
*command />`php artisan migrate:status` and then
*command />`php artisan migrate:refresh` and then
*command />`php artisan migrate:status`
that's all your done with createing with tables in mysql

I normally try several things:
In the console do rollbacks till you get 'nothing to rollback':
php artisan migrate:rollback
Then, check your article migration file and look for down function (if you haven't one you need to add it)
public function down()
{
// Drop articles table
Schema::drop('articles');
}
Save your migration article file(I know it sounds dumb, but it happened to me before). I would recommend to change the name of the file also, from:
2017_02_13_145946_create_article_table.php, to:
2017_02_13_145946_create_articles_table.php
Use:
composer dump-autoload
Go to your database(laravel_db in this case) and check if there are any table(Mysql Console):
show databases;
use laravel_database:
show tables;
If there are not any table but migrations, delete it using:
drop table migrations;
Once you have the database empty, run the migrations from console:
php artisan migrate
Finally, if not errors being trowed, check the tables created(Mysql Console):
show tables;

How to migrate specific migration file in PHP laravel - Nothing to migrate message

I have a migration file that I want to run, (only this file not all the migrations file).
I run this command:
php artisan migrate --path=/database/migrations/2019_08_21_225302_delete_encode_crids_ssp.php
In vscode I open the terminal and get this message:
How I can make it to run this specific file, (not want all the files just this file)
Project tree:
this is the code:
public function up()
{
Schema::table('ssp', function (Blueprint $table) {
$table->dropColumn('encode_crids');
});
}
try to do again and get this:
and again:
If you want to re-run the migration with force, use migrate:refresh
php artisan migrate:refresh --path=/database/migrations/2019_08_21_225302_delete_encode_crids_ssp.php
With using refresh() command
With using fresh() command

"php artisan migrate" shows "nothing to migrate"

I am new to laravel.
I am working on laravel version 6.
I have created migration.
It works nicely the first time, but if i change something in the migration file and then i run php artisan migrate it shows nothing to migrate.
I tried php artisan migrate --path as well but it does not work.
To make it work i have to delete the migration file and create it again.
I don't want to use php artisan migrate:fresh.
what should i do to run only one migrations file which has been changed?
When you run php artisan migrate it'll check migration table if there is no new file in the migration folder it'll show you nothing to migrate.
If you want to rollback last migration.
To rollback the latest migration operation, you may use the rollback command. This command rolls back the last "batch" of migrations, which may include multiple migration files:
php artisan migrate:rollback
It'll delete the last created table.
The migrate:reset command will roll back all of your application's migrations:
php artisan migrate:reset
The migrate:fresh command will drop all tables.
php artisan migrate:fresh
php artisan migrate:fresh --seed
more info : document
Sadly impossible. The best workaround is to use seeders and use php artisan db:seed after you use php artisan migrate:fresh. Why don't you want to use that?
there is two things to do you that you can use
1. In your database there is a table called migrations. Delete the rows from there which one is you want to migrate. That should be there.
2.create a folder inside of database/migrations/folder. And put the migrations file inside the folder then in your command prompt run this below command:
php artisan migrate:refresh --path=database/migrations/folder
option 2 is better than the option 1. I always use this. So i recommend option 2. This should be work
If you have seeder data then you simply do: php artisan migrate: fresh -- seed . It help to re-migrate your migration with seeder data
You didn't understand well migrations mechanics.
but if i change something in the migration file and then i run php artisan migrate it shows nothing to migrate
You write migration to make some changes in database and run it once. If you want to do next updates to database you need next migration.
During development process you can rerun migrations by php artisan migrate:fresh, but on production make sure your migration makes everything you want.
Laravel stores informations about migrations in database in table 'migrations'. If you want to reset some migrations files you can try deleting or edit some records in that table.
Have you checked that the migration has already run or not in the migration table.
If its run then there will be a row respective to your migration.
If you do changes to an old migration than nothing will be reflected when you run command php artisan migrate, as it has already been migrated.
For every modification on existing (already migrated tables) you will have to make a new migration with modifications only. If you have "users" table migration 2014_10_12_000000_create_users_table like:
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
and you need to split "name" column, will have to php artisan make:migration alter_table_users --table="users" and add what you want to change:
Schema::table('users', function (Blueprint $table) {
$table->renameColumn('name', 'first_name'); // rename column
$table->string('last_name'); // add new column });
Reverse
public function down()
{
Schema::table('users', function (Blueprint $table) {
$table->renameColumn('first_name', 'name');
$table->dropColumn('last_name');
});
}
Nou you can use php artisan migrate
Documentation: https://laravel.com/docs/6.x/migrations#modifying-columns
No one replied question "Akshay Rathod" but "Militaru" replied exactly what he need php artisan make:migration alter_table_users --table="users" and copy you new fields inside the up() function as under
public function up()
{
Schema::table('users', function (Blueprint $table) {
$table->string('userimage')->nullable();
$table->string('contact_no')->nullable();
$table->string('website')->nullable();
$table->string('country_id')->nullable();
$table->string('timezone')->nullable();
$table->string('currency')->nullable();
$table->string('communication_email')->default(1);
$table->string('communication_phone')->default(0);
$table->string('allow_marketing')->default(0);
});
}

php artisan migrate not working properly

i am new to laravel and i ran the auth file to make a register and login etc...
i have 3 migrations file inside the migrations folder: user table reset_password table and user_profile table: the problem is when i ran: php artisan migrate it only create the user table without the 2 other table so i tried these commands:php artisan migrate:rollback, php artisan migrate:refresh, php artisan config:cache php artisan config cache:clear and then i ran :php artisan migrate and only user table was created... any idea? thank you
I am also facing the same issue, while you are running php artisan migrate, the command starts migrating the table and while migrating users table it is throwing some error like:
[Illuminate\Database\QueryException]
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key
was too long; max key length is 767 bytes (SQL: alter table
users add unique users_email_unique(email))
so, only user table is migrated and the process stops with the above error. If this is the issue, then you have to solve it and after that delete the users table and again migrate, every thing will be fine.
To fix the above issue, all you have to do is to edit your app/Providers/AppServiceProvider.php file and add to the boot method a default string length like:
use Illuminate\Support\Facades\Schema;
function boot()
{
Schema::defaultStringLength(191);
}
and again migrate, everything will be fine.
I Found the solution for this
First set this in App/Providers/AppServiceProvider.php
use Illuminate\Support\Facades\Schema;
public function boot()
{
Schema::defaultStringLength(191);
}
Then Migrate Cmd And at Last
php artisan migrate:fresh
after that migration works

Laravel won't let me migrate a table because it already exists

I am trying to use Laravel Migration to create SQL tables but it won't let me.
Here is the error:
SQLSTATE[42S01]: Base table or view already exists: 1050 Table
'mytable' already exists
Here is my code:
Schema::create('mytable', function (Blueprint $table) {
$table->increments('id');
$table->foreign('othertable_id')
->references('id')->on('othertable')
->onDelete('cascade');
$table->string('variable');
$table->timestamps();
});
}
{
Schema::drop('mytable');
}
I have also checked if other migrations are called "mytable" but they are not, so I am not sure where this come from.
I tried the following:
First
php artisan migrate:refresh
Which gave me an error
And then I deleted the entire database altogheter and used:
php artisan migrate
And still got the error
In laravel 5.5 and > you can use:
$ php artisan migrate:fresh
// ( not migrate:refresh wich is a different command)
This command first drops all tables and then reruns all migrations
If you have the table in DB and dont want migrate create it, you can ignore it by check Schema::hasTable before create
public function up()
{
if(Schema::hasTable('products')) return; //add this line to migration file
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
});
}
I had neither removed the migration entry nor dropped the table manually from the database
In my case, the solution is open up the tinker from the composer
$ php artisan tinker
>>> Schema::drop('users')
>>> Schema::drop('password_resets')
>>> Schema::drop('orders')
>>> exit
php artisan migrate
Here is the result of the above commands executed

Also define the method down(), if it doesn't exist.
Otherwise, it'll show
SQLSTATE[42S02]: Base table or view not found: 1051 Unknown table 'XYZ.ABC' (SQL: drop table ABC)
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('ABC');
}
Try this,
Add following line :Schema::dropIfExists('mytable'); inside the Up() function at the very beggining exactly before creating schema for the mytable. i.e. before following code. Schema::create('mytable', function (Blueprint $table)
do composer dump, remove the table manually from the database and also remove the migration entry for the the table you want to remove from the migration table and rerun the migration again to see what happens.
The error says that the table mytable does already exist in the DB. You should rollback the migration:
php artisan migrate:rollback
And migrate again:
php artisan migrate
in my case, I need to dump the SQL schema,
run this command:
php artisan schema:dump
then run PHP artisan migrate command again
go to app>Providers>AppServiceProvider.php and copy paste this at the top:
use Illuminate\Support\Facades\Schema;
then go to function inside of it named 'Boot()' and copy paste this one:
Schema::defaultStringLength(191);
now go to your your database and delete your database completely, then go to console:
php artisan cache:clear
php artisan config:cache
then create a new database with same name and go back to consol and write :
php artisan migrate (congrats your database now shows em all)

How can I modify a migration in Laravel?

I'm trying to modify a existing migration. Here is my current migration class:
class CreateLogForUserTable extends Migration
{
public function up()
{
Schema::create('log_for_user', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id');
$table->string('table_name');
$table->string('error_message');
$table->unsignedTinyInteger('error_code');
$table->timestamps();
});
}
public function down()
{
Schema::drop('log_for_user');
}
}
I've executed the php artisan migrate command once. Now I need to add ->nullable() method to the error_message column. So I edited my migration, something like this:
.
.
$table->string('error_message')->nullable();
.
.
But when I execute php artisan migrate again, it says:
Nothing to migrate.
How can I apply the new version of the migration?
You should create a new migration using command:
php artisan make:migration update_error_message_in_log_for_user_table
Then, in that created migration class, add this line, using the change method like this:
class UpdateLogForUserTable extends Migration
{
public function up()
{
Schema::table('log_for_user', function (Blueprint $table) {
$table->string('error_message')->nullable()->change();
});
}
public function down()
{
Schema::table('log_for_user', function (Blueprint $table) {
$table->string('error_message')->change();
});
}
}
To make these changes and run the migration, use the command:
php artisan migrate
and to rollback the changes, use the command:
php artisan migrate:rollback
You may rollback a limited number of migrations by providing the step option to the rollback command. For example, the following command will rollback the last five migrations:
php artisan migrate:rollback --step=5
See more about Modifying columns with Migration
If your app is not in production and you seed your data, the best you can do is to run:
php artisan migrate:refresh --seed
This command will drop all tables and recreate them. Then it will seed the data.
If you will create additional migrations for each change during development, you'll end up with hundreds of migrations classes.
You can use the change method, it allows you to modify some existing column types to a new type or modify the column's attributes.
For example modify a column to be nullable:
Schema::table('log_for_user', function ($table) {
$table->string('error_message')->nullable()->change();
});
But first of all you'll need the doctrine/dbal package
composer require doctrine/dbal
There is one more option. Roll back the migration, edit the file, and run it again.
This is a fairly common thing to do on a local development server while you're working out the bugs in a new piece of code. Using the method from the accepted answer, you might end up with 17 migrations for creating a single table!
php artisan migrate
# realize you've made an error
php artisan migrate:rollback
# edit your migration file
php artisan migrate
The number of steps back to take can be specified on the command line if needed.
# undo the last 3 migrations
php artisan migrate:rollback --step=3
Or you can specify a particular migration that needs undoing.
# undo one specific migration
php artisan migrate:rollback --path=./database/migrations/2014_10_12_100000_create_users_table.php
There are 2 ways to do this:
Run php artisan migrate:refresh. This will rollback all your
migrations and migrate all your migrations. If you run this command,
all the data inserted in your database will be lost.
Run php artisan make:migration enter_your_migration_name_here.
Then insert this in your migration:
$table->string('error_message')->nullable()->change();
Then run php artisan migrate to make your table changes. (Take note that when you do this, you have require composer require doctrine/dbal in your composer)
