Do not prefix reader method names with get_.

  def get_name
Severity: Minor
Found in app/models/folder_node.rb by rubocop

This cop makes sure that accessor methods are named properly.

Example:

# bad
def set_attribute(value)
end

# good
def attribute=(value)
end

# bad
def get_attribute
end

# good
def attribute
end

Use snake_case for variable names.

    dropDate = AssignmentDueDate.where(parent_id: assignment.id, deadline_type_id: '6').first
Severity: Minor
Found in app/models/sign_up_topic.rb by rubocop

This cop makes sure that all variables use the configured style, snake_case or camelCase, for their names.

Example: EnforcedStyle: snake_case (default)

# bad
fooBar = 1

# good
foo_bar = 1

Example: EnforcedStyle: camelCase

# bad
foo_bar = 1

# good
fooBar = 1

  has_many :review_response_maps, foreign_key: 'reviewee_id'
Severity: Minor
Found in app/models/assignment_team.rb by rubocop

This cop looks for has_many or has_one associations that don't specify a :dependent option. It doesn't register an offense if :through option was specified.

Example:

# bad
class User < ActiveRecord::Base
  has_many :comments
  has_one :avatar
end

# good
class User < ActiveRecord::Base
  has_many :comments, dependent: :restrict_with_exception

This cop checks for duplicated instance (or singleton) method definitions.

Tagging a string as html safe may be a security risk.
Open

    html.html_safe
Severity: Minor
Found in app/models/text_field.rb by rubocop

This cop checks for the use of output safety calls like htmlsafe, raw, and safeconcat. These methods do not escape content. They simply return a SafeBuffer containing the content as is. Instead, use safe_join to join content and escape it and concat to concatenate content and escape it, ensuring its safety.

Example:

user_content = "hi"

# bad
"
#{user_content}
".html_safe
# => ActiveSupport::SafeBuffer "
hi
"

# good
content_tag(:p, user_content)
# => ActiveSupport::SafeBuffer "
<b>hi</b>
"

# bad
out = ""
out << "
  • #{user_content}
    • "
out << "
  • #{user_content}
    • "
out.html_safe
# => ActiveSupport::SafeBuffer "
  • hi
    • 

  • hi
    • "

# good
out = []
out << content_tag(:li, user_content)
out << content_tag(:li, user_content)
safe_join(out)
# => ActiveSupport::SafeBuffer
#    "
  • <b>hi</b>
    • 

  • <b>hi</b>
    • "

# bad
out = "
    trusted content
    ".html_safe
out.safe_concat(user_content)
# => ActiveSupport::SafeBuffer "
    trusted_content
    
hi"

# good
out = "
    trusted content
    ".html_safe
out.concat(user_content)
# => ActiveSupport::SafeBuffer
#    "
    trusted_content
    <b>hi</b>"

# safe, though maybe not good style
out = "trusted content"
result = out.concat(user_content)
# => String "trusted contenthi"
# because when rendered in ERB the String will be escaped:
# <%= result %>
# => trusted content<b>hi</b>

# bad
(user_content + " " + content_tag(:span, user_content)).html_safe
# => ActiveSupport::SafeBuffer "hi <span><b>hi</b></span>"

# good
safe_join([user_content, " ", content_tag(:span, user_content)])
# => ActiveSupport::SafeBuffer
#    "<b>hi</b> <span>&lt;b&gt;hi&lt;/b&gt;</span>"

    Convert if nested inside else to elsif.
    Open

                       if User.find(user_id).role.name != "Teaching Assistant"
    Severity: Minor
    Found in app/models/questionnaire_node.rb by rubocop

    If the else branch of a conditional consists solely of an if node, it can be combined with the else to become an elsif. This helps to keep the nesting level from getting too deep.

    Example:

    # bad
if condition_a
  action_a
else
  if condition_b
    action_b
  else
    action_c
  end
end

# good
if condition_a
  action_a
elsif condition_b
  action_b
else
  action_c
end

    Specify an :inverse_of option.
    Open

      belongs_to :assignment, class_name: 'Assignment', foreign_key: 'reviewed_object_id'
    Severity: Minor
    Found in app/models/assignment_survey_response_map.rb by rubocop

    This cop looks for has(one|many) and belongsto associations where ActiveRecord can't automatically determine the inverse association because of a scope or the options used. This can result in unnecessary queries in some circumstances. :inverse_of must be manually specified for associations to work in both ways, or set to false to opt-out.

    Example:

    # good
class Blog < ApplicationRecord
  has_many :posts
end

class Post < ApplicationRecord
  belongs_to :blog
end

    Example:

    # bad
class Blog < ApplicationRecord
  has_many :posts, -> { order(published_at: :desc) }
end

class Post < ApplicationRecord
  belongs_to :blog
end

# good
class Blog < ApplicationRecord
  has_many(:posts,
    -> { order(published_at: :desc) },
    inverse_of: :blog
  )
end

class Post < ApplicationRecord
  belongs_to :blog
end

# good
class Blog < ApplicationRecord
  with_options inverse_of: :blog do
    has_many :posts, -> { order(published_at: :desc) }
  end
end

class Post < ApplicationRecord
  belongs_to :blog
end

    Example:

    # bad
class Picture < ApplicationRecord
  belongs_to :imageable, polymorphic: true
end

class Employee < ApplicationRecord
  has_many :pictures, as: :imageable
end

class Product < ApplicationRecord
  has_many :pictures, as: :imageable
end

# good
class Picture < ApplicationRecord
  belongs_to :imageable, polymorphic: true
end

class Employee < ApplicationRecord
  has_many :pictures, as: :imageable, inverse_of: :imageable
end

class Product < ApplicationRecord
  has_many :pictures, as: :imageable, inverse_of: :imageable
end

    Example:

    # bad
# However, RuboCop can not detect this pattern...
class Physician < ApplicationRecord
  has_many :appointments
  has_many :patients, through: :appointments
end

class Appointment < ApplicationRecord
  belongs_to :physician
