BrowserCmsTables#self.up calls 't.integer "lock_version", :default => 0' 6 times

Duplication occurs when two fragments of code look nearly identical, or when two fragments of code have nearly identical effects at some conceptual level.

Reek implements a check for Duplicate Method Call.

Example

Here's a very much simplified and contrived example. The following method will report a warning:

def double_thing()
  @other.thing + @other.thing
end

One quick approach to silence Reek would be to refactor the code thus:

def double_thing()
  thing = @other.thing
  thing + thing
end

A slightly different approach would be to replace all calls of double_thing by calls to @other.double_thing:

class Other
  def double_thing()
    thing + thing
  end
end

The approach you take will depend on balancing other factors in your code.

ThreeScale::Swagger::Autocomplete#self.fix! manually dispatches method call
Open

Severity: Minor
Found in app/lib/three_scale/swagger/autocomplete.rb by reek

Reek reports a Manual Dispatch smell if it finds source code that manually checks whether an object responds to a method before that method is called. Manual dispatch is a type of Simulated Polymorphism which leads to code that is harder to reason about, debug, and refactor.

Example

class MyManualDispatcher
  attr_reader :foo

  def initialize(foo)
    @foo = foo
  end

  def call
    foo.bar if foo.respond_to?(:bar)
  end
end

Reek would emit the following warning:

test.rb -- 1 warning:
  [9]: MyManualDispatcher manually dispatches method call (ManualDispatch)

Severity: Minor
Found in app/lib/three_scale/xml/builder.rb by reek

Class variables form part of the global runtime state, and as such make it easy for one part of the system to accidentally or inadvertently depend on another part of the system. So the system becomes more prone to problems where changing something over here breaks something over there. In particular, class variables can make it hard to set up tests (because the context of the test includes all global state).

For a detailed explanation, check out this article

Example

Given

class Dummy
  @@class_variable = :whatever
end

Reek would emit the following warning:

reek test.rb

test.rb -- 1 warning:
  [2]:Dummy declares the class variable @@class_variable (ClassVariable)

Getting rid of the smell

You can use class-instance variable to mitigate the problem (as also suggested in the linked article above):

class Dummy
  @class_variable = :whatever
end
