When to Apply

Apply these rules when developing and maintaining Rails code.

Rules for Rails Usage

• •

  Try to keep things alphabetical within a section, such as all of the has_many statements.

• •

  Put a blank line after all associations are defined.

• •

  Put a blank line after all validations are defined.

• •

  Delegations should go after modules are included.

• •

  Associations should appear after delegations and before validations.

• •

  accepts_nested_attributes_for should appear after validations.

• •

  Scopes should appear after accepts_nested_attributes_for.

• •

  When organizing Rails model files, follow this order:

  1. •Schema comment (annotate gem).
  2. •Module includes.
  3. •Constants.
  4. •Delegates.
  5. •Gems/Plugins (has_paper_trail, has_secure_token, etc.).
  6. •Callbacks (alphabetized: after_, before_, around_*).
  7. •Associations.
  • •belongs_to (alphabetized).
  • •has_one.
  • •has_many.
  • •has_and_belongs_to_many.
  1. •Validations.
  • •validates (alphabetized by attribute).
  • •validate (alphabetized by method name).
  1. •Scopes (alphabetized).
  2. •Class methods (self.) - alphabetized.
  3. •Instance methods - alphabetized.
  4. •Ransackable methods (ransackable_associations, ransackable_attributes).
  5. •Private methods - alphabetized.

Resources

See the skills file for Ruby Coding Preferences.

JavaScript/Vue

• •Order computed properties alphabetically.
• •Order imports alphabetically within groups.
• •Use arrow functions for callbacks.

Vue

• •Try to add whitespace between elements that make up sections to make things easier to read.
• •Order the const assignment statements alphabetically when possible.

Testing

• •Use :aggregate_failures for multiple expectations in RSpec.
• •Prefer let! over before blocks for creating test data.
• •When possible, set a subject with a variable name to reduce repetition in expect statements.
• •Align the left brace of multiple, contiguous (no blank line between) let and let! statements.
• •Separate a multiline let or let! statement with a blank line.
