Prefer before_action over before_filter.
Open

  before_filter :authorize, :except => [:update]
Severity: Minor
Found in app/controllers/user_reports_controller.rb by rubocop

This cop enforces the consistent use of action filter methods.

The cop is configurable and can enforce the use of the older somethingfilter methods or the newer somethingaction methods.

If the TargetRailsVersion is set to less than 4.0, the cop will enforce the use of filter methods.

Example: EnforcedStyle: action (default)

# bad
after_filter :do_stuff
append_around_filter :do_stuff
skip_after_filter :do_stuff

# good
after_action :do_stuff
append_around_action :do_stuff
skip_after_action :do_stuff

Example: EnforcedStyle: filter

# bad
after_action :do_stuff
append_around_action :do_stuff
skip_after_action :do_stuff

# good
after_filter :do_stuff
append_around_filter :do_stuff
skip_after_filter :do_stuff

Severity: Minor
Found in app/controllers/organisations_controller.rb by rubocop

end

# good
foo.save && return

# good
if foo && bar
end

Example: EnforcedStyle: conditionals

# bad
if foo and bar
end

# good
foo.save && return

# good
foo.save and return

# good
if foo && bar

Use the new Ruby 1.9 hash syntax. (https://github.com/bbatsov/ruby-style-guide#hash-literals)
Open

    CSV.parse(csv_text, :headers => true).each do |row|
Severity: Minor
Found in app/models/category.rb by rubocop

This cop checks hash literal syntax.

It can enforce either the use of the class hash rocket syntax or the use of the newer Ruby 1.9 syntax (when applicable).

A separate offense is registered for each problematic pair.

The supported styles are:

  • ruby19 - forces use of the 1.9 syntax (e.g. {a: 1}) when hashes have all symbols for keys
  • hash_rockets - forces use of hash rockets for all hashes
  • nomixedkeys - simply checks for hashes with mixed syntaxes
  • ruby19nomixed_keys - forces use of ruby 1.9 syntax and forbids mixed syntax hashes

Example: EnforcedStyle: ruby19 (default)

# bad
{:a => 2}
{b: 1, :c => 2}

# good
{a: 2, b: 1}
{:c => 2, 'd' => 2} # acceptable since 'd' isn't a symbol
{d: 1, 'e' => 2} # technically not forbidden

Example: EnforcedStyle: hash_rockets

# bad
{a: 1, b: 2}
{c: 1, 'd' => 5}

# good
{:a => 1, :b => 2}

Example: EnforcedStyle: nomixedkeys

# bad
{:a => 1, b: 2}
{c: 1, 'd' => 2}

# good
{:a => 1, :b => 2}
{c: 1, d: 2}

Example: EnforcedStyle: ruby19nomixed_keys

# bad
{:a => 1, :b => 2}
{c: 2, 'd' => 3} # should just use hash rockets

# good
{a: 1, b: 2}
{:c => 3, 'd' => 4}

Unused block argument - validation. If it's necessary, use _ or _validation as an argument name to indicate that it won't be used. (https://github.com/bbatsov/ruby-style-guide#underscore-unused-vars)
Open

    import(filename, limit, false) do |row, validation|
Severity: Minor
