The <code>db:seed</code> rake task primarily just loads the <code>db/seeds.rb</code> script. Therefore just execute that file to load the data.

<pre><code>load "#{Rails.root}/db/seeds.rb"

# or

Rails.application.load_seed
</code></pre>

Where to place that depends on what testing framework you are using and whether you want it to be loaded before every test or just once at the beginning. You could put it in a <code>setup</code> call or in a <code>test_helper.rb</code> file.

We're invoking db:seed as a part of db:test:prepare, with:

<code>Rake::Task["db:seed"].invoke</code>

That way, the seed data is loaded once for the entire test run, and not once per test class.

blocks|key|1214974|text|将如下内容放入lib/+task+/test_seed.rake应该会在db:test:load之后调用种子任务：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1214975|namespace+:db+do

Putting something like this in lib/tasks/test_seed.rake should invoke the seed task after db:test:load:

<pre><code>namespace :db do
 namespace :test do
 task :load =&gt; :environment do
 Rake::Task["db:seed"].invoke

I'd say it should be 

<pre><code>namespace :db do
 namespace :test do
 task :prepare =&gt; :environment do

Because db:test:load is not executed if you have config.active_record.schema_format = :sql (db:test:clone_structure is)

Adding <code>Rake::Task["db:seed"].invoke</code> to the <code>db:test:prepare</code> rake task did not work for me. If I prepared the database with <code>rake db:test:prepare</code>, and then entered the console within the test environment, all my seeds were there. However, the seeds did not persist between my tests.

Adding <code>load "#{Rails.root}/db/seeds.rb"</code> to my setup method worked fine, though.

I would love to get these seeds to load automatically and persist, but I haven't found a way to do that yet!

blocks|key|1430039|text|对于那些使用seedbank的人来说，它改变了种子加载的方式，所以你可能不能/不想使用这里提供的load+...解决方案。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1430040|仅仅是将Rake::Task['db:seed'].invoke放入test_helper中，就会产生：|1430041|Don't+know+how+to+build+task+'db:seed'+(RuntimeError)|code-block|syntax|javascript|1430042|但当我们在此之前添加load_tasks时，它起作用了：|1430043|MyApp::Application.load_tasks

For those using seedbank, it changes how seeds are loaded, so you probably can't/don't want to use the <code>load ...</code> solution provided here.

And just putting <code>Rake::Task['db:seed'].invoke</code> into test_helper resulted in:

<pre><code>Don't know how to build task 'db:seed' (RuntimeError)
</code></pre>

But when we added load_tasks before that, it worked:

<pre><code>MyApp::Application.load_tasks
Rake::Task['db:seed'].invoke
</code></pre>

blocks|key|1215249|text|我相信上面的Steve's+comment应该是正确的答案。您可以使用Rails.application.load_seed将种子数据加载到您的测试环境中。但是，加载此数据的时间和频率取决于以下几点：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1215250|使用Minitest|1215251|没有一种方便的方法可以在所有测试之前运行一次此文件(请参阅this+Github+issue)。您需要在每次测试之前加载一次数据，很可能是在测试文件的设置方法中：|1215252|#+test/models/my_model_test.rb

I believe <a href="https://stackoverflow.com/questions/1574797/how-to-load-dbseed-data-into-test-database-automatically#comment25538690_1574848">Steve's comment</a> above should be the correct answer. You can use <code>Rails.application.load_seed</code> to load seed data into your test envoironment. However, when and how often this data is loaded depends on a few things:

<h1>Using Minitest</h1>

There is no convenient way to run this file once before all tests (see <a href="https://github.com/seattlerb/minitest/issues/61" rel="noreferrer">this Github issue</a>). You'll need to load the data once before each test, likely in the setup method of your test files: 

<pre><code># test/models/my_model_test.rb
class LevelTest &lt; ActiveSupport::TestCase

 def setup
 Rails.application.load_seed
 end

 # tests here...

end
</code></pre>

<h1>Using RSpec</h1>

Use RSpec's <code>before(:all)</code> method to load seed data for all test for this model: 

<pre><code>describe MyModel do
 before(:all) do
 Rails.application.load_seed
end

describe "my model..." do
 # your tests here
end
</code></pre>

Hope this helps.

blocks|key|1215321|text|根据Matt的回答，如果采用这种方法，我建议在rspec_helper.rb的before(:suite)块中调用Rails.application.load_seed，而不是在任何文件的before(:all)块中调用。这样，对于整个测试套件，种子代码只调用一次，而不是为每组测试调用一次。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1215322|rspec_helper.rb：|1215323|RSpec.configure+do+%7Cconfig%7C

Building on Matt's answer, if taking that sort of route, I recommend calling <code>Rails.application.load_seed</code> in a <code>before(:suite)</code> block in <code>rspec_helper.rb</code> rather than in a <code>before(:all)</code> block in any file. That way the seeding code is invoked only once for the entire test suite rather than once for each group of tests.

rspec_helper.rb:

<pre><code>RSpec.configure do |config|
 ...
 config.before(:suite) do
 Rails.application.load_seed
 end
 ...
end

</code></pre>

I'm attempting to use the new standard way of loading seed data in Rails 2.3.4+, the <code>db:seed</code> rake task.

I'm loading constant data, which is required for my application to really function correctly.

What's the best way to get the <code>db:seed</code> task to run before the tests, so the data is pre-populated?

How to load db:seed data into test database automatically?

数据库

我正在尝试使用在Rails 2.3.4+中加载种子数据的新标准方法，即db:seed rake任务。我正在加载常量数据，这是我的应用程序真正正常工作所必需的。在测试之前运行db:seed任务以便预先填充数据的最佳方法是什么？
