Is there a way in the Rails Console to print a table of database contents?

I think you should first use the hirb gem which provides a very pleasant way to print your tables columns.

1. Install hirb gem: gem install hirb
2. Add this gem to your project's Gemfile: gem 'hirb'
3. Go to your project's root folder and run Rails console: rails c

4. Enable hirb in the console:

   require 'hirb'Hirb.enable

If you want to limit the number of rows to display, you can do:

Model.limit(n)

For instance:

User.limit(5)

You can also specify the fields that you want to display using select:

User.select("name, email").limit(5)

You can also checkout table_print, it'll work something like this:

$ gem install table_print$ rails c> require 'table_print'> tp Book.allAUTHOR            | SUMMARY                         | TITLE-----------------------------------------------------------------------Michael Connelly  | Another book by Michael Con...  | The Fifth WitnessManning Mardale   | From acclaimed historian Ma...  | Malcolm XTina Fey          | Worth it. -Trees                | Bossypants

With hirb:

require 'hirb'puts Hirb::Helpers::Table.render(ARRAY_OF_OBJECT_OR_HASHES)# Examples:puts Hirb::Helpers::Table.render([[1, "Terminator I"], [2, "Terminator II"]])+---+---------------+| 0 | 1             |+---+---------------+| 1 | Terminator I  || 2 | Terminator II |+---+---------------+puts Hirb::Helpers::Table.render([{ id: 1, name: "Terminator I" }, { id: 2, name: "Terminator II" }])+----+---------------+| id | name          |+----+---------------+| 1  | Terminator I  || 2  | Terminator II |+----+---------------+# specifying the order of the fieldsputs Hirb::Helpers::Table.render([{ id: 1, name: "Terminator I" }, { id: 2, name: "Terminator II" }], fields: [:name, :id])+---------------+----+| name          | id |+---------------+----+| Terminator I  | 1  || Terminator II | 2  |+---------------+----+
