    <p>I am new to ruby. I am simply attempting to set up Devise. I am following the instructions at <a href="https://github.com/plataformatec/devise" rel="nofollow">https://github.com/plataformatec/devise</a> and when I get to the <code>rake db:migrate</code> command, it tells me the rake is aborted and there is "no implicit conversion of nil into String". It's frustrating since I am doing exactly what the guide/videos are doing and I get an error. </p> <p>See error below.</p> <pre><code>User$ rake db:migrate rake aborted! no implicit conversion of nil into String /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/sqlite3_adapter.rb:24:in `initialize' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/sqlite3_adapter.rb:24:in `new' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/sqlite3_adapter.rb:24:in `sqlite3_connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:440:in `new_connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:450:in `checkout_new_connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:421:in `acquire_connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:356:in `block in checkout' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:355:in `checkout' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:265:in `block in connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:264:in `connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:546:in `retrieve_connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_handling.rb:79:in `retrieve_connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/connection_handling.rb:53:in `connection' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/migration.rb:863:in `initialize' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/migration.rb:764:in `new' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/migration.rb:764:in `up' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/migration.rb:742:in `migrate' /usr/local/rvm/gems/ruby-1.9.3-p392/gems/activerecord-4.0.0/lib/active_record/railties/databases.rake:42:in `block (2 levels) in &lt;top (required)&gt;' Tasks: TOP =&gt; db:migrate (See full trace by running task with --trace) </code></pre> <p>Thank you.</p>

    1. COI'm not certain, so I don't want to suggest this as an answer, but it seems like it could be that you haven't created the database or the connection information in `config/database.yml` isn't present/accurate.

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).
