I had glass_posts table in database like that
Schema::create('glass_posts', function (Blueprint $table) {
$table->increments('id')->unsigned();
$table->integer('category_id')->unsigned();
$table->string('title', 255);
$table->string('slug', 255)->unique();
$table->text('fulltext')->nullable();
$table->string('image', 255)->nullable();
$table->timestamps();
$table->softDeletes();
$table->foreign('category_id')
->references('id')
->on('glass_categories')
->onDelete('RESTRICT');
$table->index('published');
});
then I decided to insert one more field gallery
Schema::create('glass_posts', function (Blueprint $table) {
$table->increments('id')->unsigned();
$table->integer('category_id')->unsigned();
$table->string('title', 255);
$table->string('slug', 255)->unique();
$table->text('fulltext')->nullable();
$table->string('image', 255)->nullable();
$table->string('gallery', 255)->nullable();
$table->timestamps();
$table->softDeletes();
$table->foreign('category_id')
->references('id')
->on('glass_categories')
->onDelete('RESTRICT');
$table->index('published');
});
So I delete glass_posts table from DB, then delete value 2020_03_29_104428_create_glass_tables from migrations database and then I run php artisan migrate
Now when I go to DB I see table with new field, but when I output value from database dd($item) I see all fields, except gallery.
It is not clear for me why it is so.
I tried to clear cache, but no help.
php artisan route:clear
php artisan view:clear
php artisan cache:clear

As our project scaled we decided that every single data should belong to companies that created them. Therefore I'm to add a column "data_owner_company_id" that points to the company that owns given record. Yes it's possible to generate migration to add this column to each model but that is not really feasible since there is 120+ tables & models. How can i tackle this with minimum effort ?
For the model part i figured i can easily apply it to all models by inheritance, but not sure about migration.
TL;DR
How to add int column to all tables by migration ?
Database: MySQL v8
Framework: Laravel 8, PHP 7.3
It's simple if you find all the tables' names in your database, you have to loop and create columns for each and every table.
Try creating columns using queues as it will be a heavy job for 120 tables.
Check the following code:
class CreateDataOwnerCompanyIdtoEachTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up ()
{
$columns = 'Tables_in_' . env('DB_DATABASE');//This is just to read the object by its key, DB_DATABASE is database name.
$tables = DB::select('SHOW TABLES');
foreach ( $tables as $table ) {
//todo add it to laravel jobs, process it will queue as it will take time.
Schema::table($table->$columns, function (Blueprint $table) {
$table->unsignedInteger('data_owner_company_id');
});
}
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down ()
{
$columns = 'Tables_in_' . env('DB_DATABASE');//This is just to read the object by its key, DB_DATABASE is database name.
$tables = DB::select('SHOW TABLES');
foreach ( $tables as $table ) {
//todo add it to laravel jobs, process it will queue as it will take time.
Schema::table($table->$columns, function (Blueprint $table) {
$table->dropColumn('data_owner_company_id');
});
}
}
}
I'm not 100% sure that it's going to work, but here it goes:
Create class that extends Illuminate\Database\Schema\Blueprint;
In constructor call parent construntor and then
$this->unsignedBigInteger('data_owner_company_id')->nullable();
Use your new class in migrations instead of default Blueprint
I made a mistake when i was building database, so as you will see in codes, my "order_id" column in "baskets" table is referenced from "customers" table but it should have been from "orders" table,
public function up()
{
Schema::create('baskets', function (Blueprint $table) {
$table->id();
$table->unsignedBigInteger('firm_id');
$table->foreign('firm_id')
->references('id')->on('firms')
->onDelete('cascade');
$table->unsignedBigInteger('customer_id');
$table->foreign('customer_id')
->references('id')->on('customers')
->onDelete('cascade');
$table->unsignedBigInteger('order_id');
$table->foreign('order_id')
->references('id')->on('customers')
->onDelete('cascade');
$table->unsignedBigInteger('service_id');
$table->foreign('service_id')
->references('id')->on('services')
->onDelete('cascade');
$table->decimal('price', 11, 2);
$table->integer('quantity')->default(1);
$table->string('note')->nullable();
$table->timestamps();
});
}
So how can i change its reference table from "customers" to "orders" table.
Thank you all in advance.
You should be looking at the dropForeign method (scroll down a little).
This method accepts an $index argument. The documentation already shows how to write this $index. Looking at the source code you can also see how this index is being generated. At some point the createIndexName method is being called during the foreign call.
Looking at your code and the createIndexName method, we could guess the index name that is being created:
baskets_order_id_foreign
To round it up you might be able remove the foreign key by executing the following:
public function up()
{
Schema::table('baskets', function (Blueprint $table) {
$table->dropForeign('baskets_order_id_foreign');
// Add your new foreign key
});
}
In laravel 5.6, when I am trying to migrate table 'todos' it shows this error:
And this is table code:
Table code image
Edit appServiceProvider to this:
use Illuminate\Support\Facades\Schema;
public function boot()
{
Schema::defaultStringLength(191);
}
This is because Laravel changed their default databse character set to utf8mb4 (supporting emojis i.e).
See the soutiuon in Laravel documentation here (under the heading: Index Lengths & MySQL / MariaDB): https://laravel.com/docs/master/migrations#creating-indexes
I have two schemas in my postgres
public // default schema
first_user
Now I have same tables in both schemas
I changed the table structure, so I want to run the sync now,
I sync the tables using:
const db = new Sequelize(postgres_db, postgres_user, postgres_pwd, {
host: postgres_host,
port: 5432,
dialect: 'postgres',
logging: false,
});
db.sync().then(() => {
console.log('Table Synced');
}, (err) => {
console.log(err);
});
After running this my table structure inside the public schema changed successfully, but my first_user schema's table structure remains same.
How to solve this?
NOTE: I don't want to lose my data inside my table.
Finally implemented this using sequelize migrations
http://docs.sequelizejs.com/manual/tutorial/migrations.html
If you can't use Sequelize migration because of lack of Typescript support you can fall back to Migra which is easy to use.
https://djrobstep.com/docs/migra
You Can Try CREATE TABLE AS TABLE Query.
create table first_user.tableName as table public.tableName;
It will create the table with updated table structure as well as with the data.
Thanks..
I'm usinq Laravel 5 with MS Sql Server 2014.
I want to create a unique constraint but it should allow multiple null values.
Here is code I'm using. Where 'passport_no' has to be unique if not null.
Schema::create('UserProfile', function(Blueprint $table){
$table->increments('userprofile_id');
$table->integer('user_id')->unsigned();
$table->string('passport_no', 50)->unique()->nullable();
$table->foreign('user_id')->references('id')->on('users')
->onUpdate('cascade')->onDelete('cascade');
});
This is an ancient question, but sill needs answering. As stated above, SQL Server from 2008, including Azure SQL, supports a special index that will work around it. In your database migration you can check the driver used and substitute the database builder standard SQL with an MSSQL-specific statement.
This migration example is for Laravel 5+, and creates a users table with a unique, but nullable, api_token column:
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->timestamps();
$table->string('name', 100)->nullable()->default(null);
// etc.
$table->string('api_token', 80)->nullable()->default(null);
if (DB::getDriverName() !== 'sqlsrv') {
$table->unique('api_token', 'users_api_token_unique');
}
});
if (DB::getDriverName() === 'sqlsrv') {
DB::statement('CREATE UNIQUE INDEX users_api_token_unique'
. ' ON users (api_token)'
. ' WHERE api_token IS NOT NULL');
}
}
you can use a unique Index and in its filter set your condition like
passport_no is not null
in this way you can solve your problem
