rails db:reset # Drops and recreates all databases from their schema for the current environment and loads the seeds. rails db:setup # Creates all databases, loads all . When working on a Rails app, you might sometimes need to drop the local database and start fresh with data loaded from db/seeds.rb, what do you do? Short answer: .The rails commands that manipulate migrations and your schema. How migrations relate to schema.rb. 1 Migration Overview. Migrations are a convenient way to alter your database . By default, every Rails app has three environments: development, test, and production, and there is a database for each of them. They are configured in .
The built-in test/unit based testing is not the only way to test Rails applications. Rails developers have come up with a wide variety of other approaches and aids for testing, including: NullDB, .For rails 3.2.12: I just checked the source and the dependencies are like this now: db:create creates the database for the current env. db:create:all creates the databases for all envs. db:drop drops the database for the current env. db:drop:all drops the databases for all envs. db:migrate runs migrations for the current env that have not run yet. db:migrate:up runs one specific .
If you want to delete only the data without touching the tables while using it inside your application or rails console : Rails.application.eager_load! ActiveRecord::Base.connection.disable_referential_integrity do ApplicationRecord.descendants.each do |model| model.delete_all end end config.before(:each, :altering_database => true) do DatabaseCleaner.strategy = :truncation end And add this config to your test context: context "when you alter the DB", :altering_database => true do. Note: this will slow down your tests, so be careful not to abuse it.
I also tried rails db:reset rails_env=development (I understand the default is development anyway..) and I tried rails db:reset rails_env=test as mentioned here Errno::EACCES: Permission denied @ unlink_internal when . rake db:drop RAILS_ENV=development It also drops my test db. rake db:drop RAILS_ENV=development Dropped database 'my_app_development' Dropped database 'my_app_test' I only want to drop my dev db. Is there a way to do this?Let's add a second database called "animals" and replicas for both databases as well. To do this, we need to change our config/database.yml from a 2-tier to a 3-tier config.. If a primary configuration key is provided, it will be used as the "default" configuration. If there is no configuration named primary, Rails will use the first configuration as default for each . It's hard to provide an answer for your case given the information you provided. In my case it failed to "maintain the schema" (spec/rails_helper.rb, ActiveRecord::Migration.maintain_test_schema!Because I used the postgres database (running in a docker container). In this case there are 2 solutions:
If you are using System Tests, bin/rails test will not run them, since they can be slow. To also run them, add an another CI step that runs bin/rails test:system, or change your first step to bin/rails test:all, which runs all tests including system tests. 3 Parallel Testing. Parallel testing allows you to parallelize your test suite. You should run rails db:migrate RAILS_ENV=test to update your test DB first. What this does is that, rather than just raising when the test schema has pending migrations, Rails will try to load the schema. An exception will now only be raised if there are pending migrations afterwards the schema has been loaded.
I tried to drop the test and development databases from one rake task like this: task :regenerate do Rails.env = "test" Rake::Task["db:drop"].invoke Rails.env = "development" Rake::Task["db:drop"].invoke end The test database was dropped successfully. But the development database was not dropped. Any ideas on how to make this work?
I have a strange issue on a rails app running on a docker container. I run RAILS_ENV=development db:drop db:create and it tries to create/drop only the test database. Rails 5.0.0. my config/database.yml is
Edit: as reported by MCAU, as of Rails 5.2 (and maybe some earlier versions), this is not actual anymore. Default values set in the active record migrations will apply not only to the database columns, but also when instantiating with Model.new(). The hereunder recommendation can still apply in the case you would want to have some computed .4.2 Setup the Database. The rails db:setup task will create the database, load the schema and initialize it with the seed data. 4.3 Resetting the Database. The rails db:reset task will drop the database and set it up again. This is functionally equivalent to rails db:drop db:setup.To recreate your database, follow these steps: Step 1: Drop the existing database by running the following command: rails db: drop. 💡 Note: Dropping the database will delete all data and cannot be undone, so proceed with caution. Step 2: Create a new database and run migrations: rails db: create rails db: migrate. Voilà!For Rails 5.2 this behaviour can be modified setting maintain_test_schema to false in test/test_helper.rb before importing rails/test_help: ActiveRecord::Base.maintain_test_schema = false require "rails/test_help" rails/test_help will check the value of maintain_test_schema to decide if it has to drop/create/migrate the test database or not.
I am updating an existing rails app to add tests. I notice that the database gets dropped prior to the test run. I tried to follow the steps outlined in this question, How to stop rspec from dropping the test database before tests, but had no luck. Is there any RSpec documentation about this database drop functionality. I have two Rails apps that use the same database. One app is managing the database through migrations but the other is just accessing it. . Task["test:prepare"].invoke, which simply runs the migrations, and then only if that task is declared - meaning pre Rails 4.1.0. For Rails 4.1.0 and above that invocation doesn't even occur anyway . Since rails generate migration has command-line options for generating migration code for creating tables, adding or changing columns, etc., it would be nice if it also had an option for dropping a table -- but it doesn't. Sure, writing the up part is simple -- just call drop_table-- but the down part, generating the table again, might not always be so simple, especially if the .
Usually there are 2 types of seed data required. Basic data upon which the core of your application may rely. I call this the common seeds. Environmental data, for example to develop the app it is useful to have a bunch of data in a known state that us can use for working on the app locally (the Factory Girl answer above covers this kind of data).; In my experience I . But, I prefer to create your database in test environment before scenario, as example: describe "specific name for this scenario" do before do @object = create(:object) # using factory girl as example end end so, this data'll be generate for each time you run your test-case, read more about creating data for rspec-test.
I am new to Stack Overflow and Ruby on Rails. My problem is, when I run the command rake db:create or rake db:migrate, the test database is affected, but the development database is not. rails (3.2.2) my database.yml: # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake".Calling rake spec or just rake will prepare your test database. Behind the scene, it calls `db:test:prepare`. To see what happens under the hood, add the trace option: rake spec --trace. The actual steps rake spec takes are; Drop the existing database: '$ rake db:drop RAILS_ENV=test' Create a new database: '$ rake db:create RAILS_ENV=test'
This will make the test database the same schema as dev. rake db:test:prepare Now, understand that db:test:prepare makes test have the same schema as dev, but with no records. To populate records in test, implement fixtures or factories (see the factory-girl gem). Factories are generally called in your test to create records for that test.rake db:drop # Drops the database from DATABASE_URL or # config/database.yml for the current RAILS_ENV # (use db:drop:all to drop all databases) By default, RAILS_ENV is not set. If you called rake db:drop during this state, all databases associated with this app will be dropped. In order to drop, say, only development: export RAILS_ENV .
4.2 Setup the Database. The bin/rails db:setup command will create the database, load the schema, and initialize it with the seed data. 4.3 Resetting the Database. The bin/rails db:reset command will drop the database and set it up again. This is functionally equivalent to bin/rails db:drop db:setup.
test_data does what it says on the tin: it provides a fast & reliable system for managing your Rails application's test data.. The gem serves as both an alternative to fixtures & factory_bot, as well a broader workflow for building test suites that will scale gracefully as your application grows in size and complexity. What it does: Establishes a fourth Rails environment (you can define custom .Active Record MigrationsMigrations are a feature of Active Record that allows you to evolve your database schema over time.
