Laravel Documentation for Migration
If you want to run the migration without saving any data in database you can :
php artisan migrate:fresh
// Refresh the database and run all database seeds...
php artisan migrate:fresh --seed

Maybe someone has faced such a situation. Unfortunately, none of Stackoverflow's tips solve this. A clean project (I managed to register the routes only). With the php artisan migrate command, the migrations table is created and immediately dropped.
Error.
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'main.migrations' doesn't exist...
When I use php artisan migrate:install it creates a migration table (it is visible in migrate:status, it also appears in the database). But php artisan migrate ruins it again, same error.
Neither migrate:fresh, migrate:rollback, nor composer dumpautoload helped. I've been fighting all evening, nothing helps.
I am new to Laravel and learning myself. I have confusion between Laravel commands "php artisan make:model" and "php artisan make:migration". What I understand is that both of these commands are used for creating table.
php artisan make:model is used to create a Model-Class, referring to the MVC Pattern.
php artisan make:migration is used to create a Migration-Class. A Migration is used to define a database-table schema. The Migrations will be executed when you run php artisan migrate, which will create the tables in your database of choice.
You can even combine these two tasks:
php artisan make:model Flight --migration
Will create a Model-Class called Flight and a migration with the filename 2022_08_01_162322_create_flights_table.
Those are two different commands.
php artisan make:model
This command will generate a Model. For exemple, you could generate a Listitem model if you build a to-do app.
php artisan make:migration
This command will generate a migration file. You will use this file to create your database table structure.
In everyday life, I prefer using the first command like this:
php artisan make:model -mc
The -mc option will ask Laravel to create a migration file and a controller file in addition to the model file. I recommend using this command to save time.
To be more clear in a simple word :
1️⃣ Model is a logic which transfers data between database and UI.
2️⃣ Database is is a collection of organised data and information. These databases contain many tables with multiple fields containing information on a company's clients or employees.
3️⃣ Migration is a logic which you can make your tables and columns programmatically and also you can have a type of version control on your database tables.
➡️ So :
While running
php artisan make:model
You have created a file to write logic to transfer data between database and UI
While running
php artisan make:migration
You have created a file which you can defining your table fields.
And after that you should run :
pho artisan migrate
Which will run your migrations and creates your tables.
🎁 Quick tip : there is also a command for creating Model, Controller and it’s migration with one command which I have mentioned below 👇
php artisan make:model -mcr
You need to first know the difference between Model and Migration:
Migration: represents the structure of an entity in your database schema.
That means that this migration when executed php artisan migrate will represent and create the table with that defined structure
Model: represents the domain logic. This logic is used to handle the data passed between the database and the user interface (View in MVC).
So, php artisan make:model Example will create a new model of Example and php artisan make:migration example_table will create a migration that refers a model.
First Do You Know What's Model And Migration
Model:Is Refer To Your Table Inside Your Database But If You Want To Refer to your table you should Make the name of the model like your Table name in database but : 1- The first letter is cabital 2-Remove 's' from the last
You Can Craete model using php artisan make:model YourModelName
Migration:is used to make rows inside your table like name,email,password
You Can Craete Migration using php artisan make:migration YourMigrationName
Is there a command/package for laravel that simplifies or automates simple Laravel migrations ?
Example : "php artisan migration:addfield --table: Posts --field: date_birth etc/parameters ..."
The goal is to simplify and automate simple actions like making small changes to tables, for example.
There is ?
You can use this package, which is created by Jeffrey Way (owner of Laracasts)
https://github.com/laracasts/Laravel-5-Generators-Extended
Are you looking a for a field to add in existing table ??Then use this
php artisan make:migration add_date_of_birth_to_posts_table --table=posts
You can directly mention the table without --table tag
php artisan make:migration add_date_of_birth_to_posts
php artisan make:migration create_users_table
This code does not generate a table on phpmyadmin.
What code should I use?
I am installing Backpack package in my project, I followed the documentation steps but when I do migrate it says "Nothing to migrate".
I've already tried to publish the migrations but nothing works.
From their documentation, the only thing that you need to migrate is the default users and password reset table that comes with laravel.
php artisan migrate #generates users table (using Laravel's default migrations)
So in case if you've already migrated those, then you can skip that part. But if you haven't then make sure you have the default migrations in database/migrations and then run php artisan migrate:refresh
