i have created my database , then i have created a table with
php artisan migrate: make create_users_table
a file has created so i modified up and down function and i typed
php artisan migrate
until now everything is ok the problem started when i tried to add
another lignes to my database , i added another information about
users and when i type
php artisan migrate
the response was Nothing to migrate and there is no change into my databse ?
3 possibilities:
Create a new migration
Rollback the last migration operation and rerun it :
php artisan migrate:rollback
php artisan migrate
Rollback all migrations and run them all again
php artisan migrate:refresh
More info here: http://laravel.com/docs/migrations
You have to create another migration, or you can refresh your previous migrations
php artisan migrate:refresh
http://laravel.com/docs/migrations
If you just added more records in a table that already exists using e.g. phpmyadmin, there is no need to run again php artisan migrate, because no extra migration is created. That's why you get the "Nothing to migrate" message.
But, if you want for example to add a new column or delete an existing one, the ideal way to do it is by creating a new migration and name it something like add_columnname_on_users_table, edit properly the new migration file, then run php artisan migrate.

In role_has_permissions table have 3 column, I want to add one more column. The column name is company id
$table->unsignedBigInteger('permission_id');
$table->string('model_type');
$table->unsignedBigInteger($columnNames['model_morph_key']);
Any way to add this
#MDMasum If I understand what you are asking right, then I believe you could add another column by generating another migration on the existing table. I am not familiar with Spatie, but I knowing Laravel, I don't see why this would not work.
You could do so with the following artisan command in CLI:
php artisan make:migration add_company_id_to_role_has_permissions_table --table=role_has_permissions
You will get a generated migration file that is named something similar to this:
2020_09_03_012345_add_company_id_to_role_has_permissions_table.php
Then modify the up function in that generated migration file accordingly.
Finally, run the following artisan command in CLI:
php artisan migrate
I have seeded my DB using php artisan db::seed. Is there a way to rollback what I have seeded into my DB?
I cannot seem to find any command like php artisan db::seed rollback.
use Undo Seeder for Laravel.
When you install UndoSeeder, the following artisan commands are made available:
db:seed-undo Undo seeds in the seeds directory.
db:seed-refresh Undo seeds run seeds again.
more Undo-Seeder
You may also seed your database using the migrate:refresh command, which will also rollback and re-run all of your migrations. This command is useful for completely re-building your database:
php artisan migrate:refresh --seed
Running Seeders
If you want to wipe out certain table, then just TRUNCATE that table, and seed it again:
php artisan db:seed --class=UsersTableSeeder
No need for additional packages for such a simple task.
The easiest method is to go into your
database/seeders
folder and manually delete the files you want to remove then run php artisan migrate:fresh.
Open the database table with whichever platform you are using (phpMyAdmin / mySql-Workbench / a DB-editor plug-in etc.) and manually delete the seeded contents. Then you will be able to reseed the table using php artisan db:seed
I was looking for something else like i have ran php artisan db:seed and after that I wanted to change something in UserSeeder, like changing an email address.
So if you want to change something in Seeder class and you have already run db:seed command.
Then first of all you have to add truncate function before any other code like if you have UserSeeder class then add below code in run function before seeding all User model:
User::truncate();
Then all you have to do is re-run the command.
php artisan db:seed
It will seed again all the classes as per your change and delete already seeded Users in Database, You can use this method for any model you want to truncate the table and re insert the records.
I deleted a table directly in my phpMyAdmin and how when i run the command php artsan migrate:rollback , i get the following error:
Failed to open:stream: No such file or directory.
I already deleted the migration file from the migrations folder , so why am i getting this error ??
I was just going through the laravel migrations documentation HERE, and i saw the below command:
php artisan migrate:rollback --step=5
So i tried the below in my command line:
php artisan migrate:rollback --step=1
To rollback my last migration , but it does't seem to work. Thats the reason i deleted the table directly in the phpMyAdmin.
Below is the error i get now , when i run the php artsan migrate:rollback:
Please try the following commands, it will be fine.
To clear cache
php artisan cache:clear
To composer autoload
composer dump-autoload
Now restart your Laravel server and it will be fine.
It will be working by now. However, it is never recommended to delete a table and a migration file directly. If that's the case, Laravel wouldn't have used migration at all. Please take care next time.
Since you removed the file before rolling back, I would suggest to delete the entry manually from your migrations table.
Search for the full name and delete just the 1 entry.
DELETE FROM `migrations` where `name` = '[2017_01_09_xxx]';
However, if your migration was already committed and pushed to remote and other people are working on the same codebase, I would suggest restoring the table on your local env and also restore the migration file with that name and remove the table by adding a new migration.
This flow will make sure that when other people work with your changes or that when you deploy and run migrations, you are able to do so without issues.
I am new to laravel and while working I created a new migration. After running the command php artisan migrate, the migration was successful. I then went back to the previous created migration and added some new fields. When I run back the command php artisan migrate, I was receiving the message Nothing to migrate. I was then supposed to run the command php artisan migrate:refresh for the changes to be applied but I did not want to rollback some migrations so I went to those migrations and I modified the last method as following
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
// The line below has been commented to prevent rollback
// Schema::drop('table-name');
}
Since then when I run php artisan migrate I get the following error:
[Symfony\Component\Debug\Exception\FatalErrorException] Class 'Carbon' not found
I have run composer update, composer dump-autoload, composer clear-cache, php artisan migrate:refresh, php artisan migrate:rollback, php artisan migrate:reset
Kindly help me solve this problem.
In your migration classes or scripts, you have used Carbon class, but forgot to import/include.
Add
use Carbon/Carbon;
in your migration scripts where you have used Carbon class and run migrations.
ref link: http://laravel.io/forum/03-12-2014-class-carbon-not-found
I would not recommend to comment some lines in the migration's down method.
Generally the down() method should always undo the operations made in the up() method.
If you want to add some fields to an existing table and don't want to loose some data by doing a refresh, then just create another migration and specify the table you want to modify. For example:
php artisan make:migration add_some_fields_to_users --table=users
You could also consider using Database Seeds so you can refresh your migrations and then seeding the database with data again. This is very powerful during development stage.
For you Carbon issue most likely the answer from #Sanrekula is what your are looking for.
I clone my project from gitlab and I make it on my new computer.
But I get nothing ouput after I run php artisan migrate and the corresponding table is not created.
Output of php artisan migrate:status below.
What the meaning of "Ran?" and why status my migration file are all "N". php artisan migrate will create these tables successfully only when the "Ran?"s are "Y"?
An Y in the Ran column means the migration has been done.
Check your .ENV file , make sure your database settings are correct, also make sure you actually created the database beforehand.
clear the entire laravel cache to stay up to date with current .env settings, it might help.
try using php artisan migrate:refresh sometime it happens with me and i find out it's already migrated
