Removing table from schema.rb
ruby-on-rails, ruby-on-rails-4
Solution
If you want to really really remove it you should prepare a migration to drop the table.
If you just remove the model ActiveRecord will still find the table in db (and that's probably why you're seeing it in `schema.rb` - if I am right that you mean file and not db schema)
EDIT:
So I tried to reproduce this, and as a result I ended up with following order of commands.
- first drop the table (make a new migration with `drop_table :locations` and run it)
- then run `rails destroy model location` (you will get an error if you destroy model first)
- run `rails c` so Rails picks up the db change and updates `schema.rb`
Problem
I had a Location model in my app, but then I went a step back with Git, when I didn't create the model yet, then after quite a while working on another branch I realized that the model had gone nowhere, and it is still in my schema. I tried to get rid of it but it still pops out of nowhere, although there are no add location migration files in my app. What is the best way to get rid of it and clean up my schema.rb? UPDATE 1 Running rails destroy model location Gives me ``` invoke active_record remove /Users/denis/Desktop/migration/templates/create_table_migration.rb remove app/models/location.rb invoke test_unit remove test/models/location_test.rb remove test/fixtures/locations.yml ``` And I can run it for the indefinite amounts, it will always give the same result Running this migration: ``` class DropLocationsTable < ActiveRecord::Migration def self.up drop_table :locations end end ``` Gives 0 result, after rake db:migrate the Locations appear in my schema.rb again UPDATE 2 ``` rails db SQLite version 3.7.12 2012-04-03 19:43:07 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> SELECT * FROM locations; sqlite> ```
