Us of different migrations dirs about ruckusing-migrations HOT 19 CLOSED

Currently this is not available. It does raise the question: during the generation process where it write the file to? The first entry in the array of directories?

from ruckusing-migrations.

Maybe an optional option in the config with an array of path to read from (and use the existing option to read from and write the files during the generation process)

from ruckusing-migrations.

Is that "optional option" must belongs to each database or you want just array declaration for 'migrations_dir' option?

from ruckusing-migrations.

I prefer an array declaration for the migrations_dir option.

from ruckusing-migrations.

Check it. What if it will be a key-array like this one: array ("main" => %ordinary_path%, "foo" => %another_path% ... )?
And for convenience and reverse compatibility this option still should accept ordinary string with path without any array declaration.
Is it suitable?

from ruckusing-migrations.

Oh, forget second part. And you could generate migrations in selected dir by corresponding param in CLI like, for instance, 'path=foo'.

from ruckusing-migrations.

That key array sounds like a good solution.

from ruckusing-migrations.

After reading the comment I still could not get what the end result of this would be. Some real command use cases with examples could be appreciated. What are the keys of the array ?
Thanks

from ruckusing-migrations.

No problem.
Keys of the array - just some name for specify pathes. Now I'm use it in error message by migration similarity.
User can specify 'migrations_dir' as well as ordinary string (default state).

Known use-cases:

1. Creating migration
   1.1 User with default state - just will get processing for the only folder. If user sets 'dir' param - just pass it without error.
   1.2 User with array in 'migrations_dir':
   1.2.1 User specified 'dir' param at script running - I use this param as destination, but will check all folders for unique migration name. If there is no path in 'migrations_dir' with such param as name - config error
   1.2.2 User doesn't specified 'dir' param at script running - I use the first key from 'migrations_dir' as destination, but will check all folders for unique migration name. If there is no path in 'migrations_dir' with such param as name - config error
2. Migrate - will form common list of tasks from all dirs from 'migrations_dir' and migrate by this list.

Feel free to correct me if i made mistake.

Real command at this moment: php ruckus.php db:create [env=production] [dir=foo]
db:migrate command without changes.

from ruckusing-migrations.

Ok guys, i did it. But there is some points.

1. Review my code as critical as you can
2. I. Just. Can't. Create. Any. Test. It's my weakest part.

Will answer any questions through 12 hours.

The thing I don't understand is why do you want multiple directories for migrations. A migration directory is related to a database. if you have multiple databases, then you need multiple environment. As of now migrations are structured based on the database. So different databases migrations are placed in different directories named according to the database name.

With this change the migrations of a particular database would be scattered over multiples folders. Does rake works like this ? It's like this will add complexity with no obvious benefit.

Thanks

This question need to address to tvbeek. I'm just implement it.
Аlternatively - you will decline my pull request and tvbeek could use my branch for this feature.
BTW, agree with you about "complexity with no obvious benefit".

from ruckusing-migrations.

When you use modules in a project you want to have the database changes in a module and not in the project. Because you can reuse the module and don't want to need to copy the migration files.

Like a simple project structure

/www
/modules
    /base
        /migations
    /auth
        /migrations
    /cms
        /migrations
/ruckusing-migrations

You have one directory with ruckusing-migrations. And multiple directories with migrations for the same database.

@tvbeek I think I now understand a little bit your problem. I think a good solution would have to be carefully thought so as to not break so many things. @tonkonogov pr is a good start but I'm pretty sure it's breaking something somewhere still not tested. I will think about it carefully and push some codes around the end of this week basing off #76 . And this will badly need some good test cases.
Thanks

from ruckusing-migrations.

I tested locally migrating and generating migrations with old config file as well as config file with 2 dirs. Still doesn't tested any other tasks.
I'll try to create unit tests for this feature at nearest weekend.

from ruckusing-migrations.

@tvbeek please checkout the new branch module-migration-dir to see if it solves your problem without any error.

```git clone -b module-migration-dir https://github.com/ruckus/ruckusing-migrations.git ruckusing-migrations-test/`

from ruckusing-migrations.

I forgot to mention the new command:

php ruckus.php db:generate create_users_table module=cms
php ruckus.php db:migrate

of course your migration_dir would be like 'migration_dir' => array('default' => '/default/path/migrations', 'cms' => '/path/to/cms/migrations')

I'm working on an update for the test cases that will gives us more test coverage. So if @tonkonogov sends a pr for the unit tests, I will just merge them. If not, when I'm done with that "tests-branch", it will cover this change

from ruckusing-migrations.

After 5 months of bad things I have finally returned to my promise about tests. I didn't forget %)

from ruckusing-migrations.

@tonkonogov I've merged your changes. Thanks a lot
