* [ci skip] remove guide section on models in migrationsLuke Steensen2014-02-261-153/+0
| | | | | | Both examples given are incorrect, and no one can seem to come up with a realistic situation where this is an actual problem. For now, it seems like the best thing to do is just scrap the section altogether.

* [ci skip] Describe precision + scale in migrationsTaryn East2013-12-201-4/+4
| | | | | | | Telling somebody that "precision sets the precision" is not very helpful. Newbies want to know what precision is *for*, likewise with scale. So I've added a very brief description for each.
* Revert "`remove_column` does not take a type argument. [ci skip]. Closes #12864"Yves Senn2013-11-131-1/+1
| | | | | | | As of Rails 4.0 `remove_column` is no longer an alias for `remove_columns`. The type is actually valid and used when issuing a rollback (new `change` method). This reverts commit 9c9d4948e428a226a19aa92c17fa6ac5833c2fb8.

* transactions can be turned off per Migration.Yves Senn2013-03-051-1/+5
| | | | | | | | | | | Closes #9483. There are SQL Queries that can't run inside a transaction. Since the Migrator used to wrap all Migrations inside a transaction there was no way to run these queries within a migration. This patch adds `self.disable_ddl_transaction!` to the migration to turn transactions off when necessary.
* Support creating a table migration generatorSammy Larbi2013-03-011-0/+21
| | | | | | | | | | | | | | | | Sometimes you want to create a table without an associated model and test, which is also not a join table. With this commit, you can now do that. Example: rails g migration create_posts title:string or rails g migration CreatePosts title:string This commit also moves the template the model generator uses for the migration to the migration templates folder, as it seems a more sensible place for it now that it is shared code.

* | Migration Guide: General fix-upSteve Klabnik2012-12-011-365/+217
|/ | | | | | | | | This introduces a bunch of editing/re-writing to the migrations guide. There were a bunch of small changes, and a few larger ones: * mysql does support transactions. * Add a section about db/seeds.rb * Largely re-wrote the first few sections
* Normalize on 'After reading this guide, you will know:'Steve Klabnik2012-11-291-1/+1
| | | | | We have three or four different introduction sentences to the guides. After this commit, we use the same one everywhere.
* Migrations: add 'Active Record' to titleSteve Klabnik2012-11-291-2/+2
| | | | | Other guides that talk about Active Record specific features include the name of the library in the title, this one should too for consistency.
* Add periods to the bullet points in guides.Steve Klabnik2012-11-291-4/+4
| | | | Talked with @fxn about this. Bullet points should have periods at the ends.
* Migrations: Fix opening bullets.Steve Klabnik2012-11-291-2/+2
| | | | The wording of these was a bit off, so I fixed them.
* Migrations: move massive paragraph out of intro.Steve Klabnik2012-11-291-10/+19
| | | | | | | Most of the guides have a few simple sentences describing what they will show you at the top. This one had a few big paragraphs. I've moved those paragraphs down to an introductory one, and written a new smaller one for the introduction. This makes this guide more consistent with the others.
