    <p>I'm pretty confused about an error I get trying to unit test a model (User) I have. I have a fixture for the model in test/fixtures/users.yml</p> <pre><code>new_user_in_unavailable_country: first_name: John last_name: Lennon email: john.lennon@pop.co.uk password: YokoOn0 country: UNITED KINGDOM </code></pre> <p>Now in test/unit/user_test.rb I have</p> <pre><code>require 'test_helper' class UserTest &lt; ActiveSupport::TestCase test "status_auto_fill_for_unavailable_country" do users(:new_user_in_unavailable_country).valid? assert users(:new_user_in_unavailable_country).status == "SUBSCRIBED" end end </code></pre> <p>So far so good. Now, here is what that generates upon rake:test:units :</p> <pre><code> Error: test_status_auto_fill_for_available_country(UserTest): ActiveRecord::StatementInvalid: Mysql2::Error: Field 'name' doesn't have a default value: INSERT INTO `countries` (`id`) VALUES (980190962) </code></pre> <p>Okay, if there is an hidden insert somewhere into table countries (which I never asked for!), I should be able to see that upon running the same code in a rails console. So I tried:</p> <pre><code>&gt; usr = User.new(:first_name =&gt; "John", :last_name =&gt; "Lennon", :email =&gt; "john.lennon@pop.co.uk", :password =&gt; "YokoOn0", :country =&gt; "UNITED KINGDOM") #&lt;User id: nil, first_name: "John", last_name: "Lennon", email: "john.lennon@pop.co.uk", hashed_password: nil, password_salt: nil, created_at: nil, updated_at: nil, organization_id: nil, country: "UNITED KINGDOM", status: nil&gt; &gt;&gt; usr.valid? (1.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (1.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (0.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (1.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (0.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (0.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (0.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (0.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' (0.0ms) SELECT COUNT(*) FROM `countries` WHERE `countries`.`available` = 1 AND `countries`.`name` = 'UNITED KINGDOM' User Exists (1.0ms) SELECT 1 FROM `users` WHERE `users`.`email` = BINARY 'john.lennon@pop.co.uk' LIMIT 1 true &gt;&gt; usr.status "SUBSCRIBED" </code></pre> <p>Okay, no insertion into countries table.</p> <p>Anyidea of what happens behind the scene that I am missing and that generates this error?</p> <pre><code>Create Country migration: class CreateCountries &lt; ActiveRecord::Migration def change create_table :countries do |t| t.string :name , :null =&gt; false t.string :iso_2_letters_code , :null =&gt; false t.string :iso_3_letters_code , :null =&gt; false t.integer :phone_code end add_index :countries , :iso_2_letters_code , :unique =&gt; true add_index :countries , :iso_3_letters_code , :unique =&gt; true end end </code></pre>

    1. COCan you share your migration file for `Country`? Looks like you have a `NOT NULL` constraint on the `name` column in `countries` table.

    2. COJust added it. Now, where in the world do I create an entry in the countries db while that does not happen when running code from rails console?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
