I am using symfony and in that I am trying to generate new migration version with the following command:
app/console doctrine:migration:diff
it is genrating new migration file but there is a table in Entity directory called transaction for this particular table i am not able to generate migration or can say the table is not being created in database. Please help me generating migration / table by script only. I don't want to generate it manually.
Thanks
Use this command to generate a migration file which will be get created in migration\ folder
php app/console make:migration
Then hit this command to reflect your entity into the database
php app/console doctrine:migration:migrate
To check you current migration status and track hit this command
php app/console doctrine:migration:status
Install symfony CLI for ease from
https://symfony.com/download
I just had the same problem: migration wasn't getting generated for a specific entity.
After a while I found out it was because of my Doctrine Cache.
I cleared the cache pool and could generate my migration properly.

I have an issue with laravel.
I have created a database named billing and connection is working fine for all tables. Now I created a new table named as masters. When I'm using this table then it is showing error base table or view masters not found
How can I resolve this issue?
This is usual for beginners. I have a few hints:
You might want to manually check the database, outside of Laravel, to
be sure the table has not been add.
Sometimes, you might just have misspelt the table name.
Did you forget to run the migration? If so, you need to run the
migration to add the table to the database. You can simple use php
artisan migrate on the command line.
If all these don't resolve it, dump you autoload files with composer and rerun your migration. You can use composer dumpautoload and then php artisan migrate:refresh
To create a migration, use the make:migration Artisan command:
php artisan make:migration create_masters_table
The new migration will be placed in your database/migrations directory.
You can use Laravel schema builder to expressively create and modify tables.
To run all of your outstanding migrations, execute the migrate Artisan command: php artisan migrate
Is there a differences between the Symfony console command make:migration and doctrine:migrations:diff?
There is no difference between these two commands.
make:migration is simply a Symfony provided wrapper for the Doctrine command.
You can run either to the exact same effect. But the symfony one requires that you have the Symfony Maker bundle, which otherwise it not required.
make:migration will create empty file for you so you can write your custom migration
doctrine:migrations:diff will compare your current database schema with entities mappings and if there is difference then it will create migration so you can update you database schema to reflect your entities mappings
Just a quick one really
I have an existing Laravel app
I want to use a migration to add some columns to an existing table
So i do the following:
php artisan make:migration add_columns_to_table
Which creates a file in my migrations folder called:
2017_10_25_124938_add_column_to_table.php
And also creates an entry in my migrations table in the database. All good.
I can edit the migration file (adding the columns etc) and run
php artisan migrate
And everything works great
Now - my question is this:
When i come to deploy to live i am presuming I would log onto the live box and run the create migration command again:
php artisan make:migration add_columns_to_table
But this will create a migration with a different name to the one i created / tested locally?
So - do i then need to manually copy the code from my local 2017_10_25_124938_add_column_to_table.php migration file to the one created on the live box?
That seems a bit backwards and fiddly
What is the best way of creating and testing a migration locally and then deploying it to live when the create migration command creates a different named migration file (and DB entry) on the live box?
Or have i got the wrong end of the stick?
The best practice is to keep migration files with the repo. While deploying the application on any environment you have to execute all migrations.
php artisan migrate
This command will run all the migrations which are not already executed in the current environment. Laravel use a table called 'migrations' to keep track of all the migrations it has run.
Is
php artisan make:model Test -m
equivalent to
php artisan make:migration create_tests_table --create=tests
?
Does make:model -m create a tests table?
In php artisan make:model Test -m, The -m flag will create a migration file for that model.
In php artisan make:migration create_tests_table --create=tests, the --create flag is the name of the table that will be created.
So yes, the -m option will create a migration file with a name like TIMESTAMP_create_tests_table.php
Update
If you find yourself in a situation when you doubt about commands, you can always run a command like this form your terminal: php artisan help make:model. You'll see an overview with some explenation about the extra options of that specific command.
No they are not equivalent; they are very different. One is creating a model AND also creating a migration while the other is just creating a migration (both migrations include a table called tests). Bear in mind that creating a model and creating a table are not the same thing. From the docs: "The Eloquent ORM included with Laravel provides a beautiful, simple ActiveRecord implementation for working with your database. Each database table has a corresponding "Model" which is used to interact with that table. Models allow you to query for data in your tables, as well as insert new records into the table."

For a fresh start,
I've deleted all my migration files, dropped all tables in MySQL and deleted all the table migrations columns in MySQL.
But when i'm running php artisan make:model Article Laravel responds by
Model created successfully.
Created Migration: 2015_04_28_181243_create_articles_table
Which is a migration file i've deleted previously! Why does it keep returning this way? and how can i get rid of it completely?
Well the make:model command generates a migration by default.
To opt-out of this add the no-migration option:
php artisan make:model Article --no-migration
