DeadlinesController#create has approx 11 statements

  def create
Severity: Minor
Found in app/controllers/deadlines_controller.rb by reek

A method with Too Many Statements is any method that has a large number of lines.

Too Many Statements warns about any method that has more than 5 statements. Reek's smell detector for Too Many Statements counts +1 for every simple statement in a method and +1 for every statement within a control structure (if, else, case, when, for, while, until, begin, rescue) but it doesn't count the control structure itself.

So the following method would score +6 in Reek's statement-counting algorithm:

def parse(arg, argv, &error)
  if !(val = arg) and (argv.empty? or /\A-/ =~ (val = argv[0]))
    return nil, block, nil                                         # +1
  end
  opt = (val = parse_arg(val, &error))[1]                          # +2
  val = conv_arg(*val)                                             # +3
  if opt and !arg
    argv.shift                                                     # +4
  else
    val[0] = nil                                                   # +5

end

(You might argue that the two assigments within the first @if@ should count as statements, and that perhaps the nested assignment should count as +2.)

JobsController#create_or_update_mutation has boolean parameter 'update'
Open

    def create_or_update_mutation(update = false)
Severity: Minor
Found in app/controllers/jobs_controller.rb by reek

Boolean Parameter is a special case of Control Couple, where a method parameter is defaulted to true or false. A Boolean Parameter effectively permits a method's caller to decide which execution path to take. This is a case of bad cohesion. You're creating a dependency between methods that is not really necessary, thus increasing coupling.

Example

Given

class Dummy
  def hit_the_switch(switch = true)
    if switch
      puts 'Hitting the switch'
      # do other things...
    else
      puts 'Not hitting the switch'
      # do other things...
    end
  end
end

Reek would emit the following warning:

test.rb -- 3 warnings:
  [1]:Dummy#hit_the_switch has boolean parameter 'switch' (BooleanParameter)
  [2]:Dummy#hit_the_switch is controlled by argument switch (ControlParameter)

Note that both smells are reported, Boolean Parameter and Control Parameter.

Getting rid of the smell

This is highly dependent on your exact architecture, but looking at the example above what you could do is:

  • Move everything in the if branch into a separate method
  • Move everything in the else branch into a separate method
  • Get rid of the hit_the_switch method alltogether
  • Make the decision what method to call in the initial caller of hit_the_switch

Feature Envy occurs when a code fragment references another object more often than it references itself, or when several clients do the same series of manipulations on a particular type of object.

Feature Envy reduces the code's ability to communicate intent: code that "belongs" on one class but which is located in another can be hard to find, and may upset the "System of Names" in the host class.

Feature Envy also affects the design's flexibility: A code fragment that is in the wrong class creates couplings that may not be natural within the application's domain, and creates a loss of cohesion in the unwilling host class.

Feature Envy often arises because it must manipulate other objects (usually its arguments) to get them into a useful form, and one force preventing them (the arguments) doing this themselves is that the common knowledge lives outside the arguments, or the arguments are of too basic a type to justify extending that type. Therefore there must be something which 'knows' about the contents or purposes of the arguments. That thing would have to be more than just a basic type, because the basic types are either containers which don't know about their contents, or they are single objects which can't capture their relationship with their fellows of the same type. So, this thing with the extra knowledge should be reified into a class, and the utility method will most likely belong there.

Example

Running Reek on:

class Warehouse
  def sale_price(item)
    (item.price - item.rebate) * @vat
  end
end

would report:

Warehouse#total_price refers to item more than self (FeatureEnvy)

since this:

(item.price - item.rebate)

belongs to the Item class, not the Warehouse.

Reek would emit the following warning:

test.rb -- 3 warnings:
  [1]:Dummy#hit_the_switch has boolean parameter 'switch' (BooleanParameter)
  [2]:Dummy#hit_the_switch is controlled by argument switch (ControlParameter)

Note that both smells are reported, Boolean Parameter and Control Parameter.

Getting rid of the smell

This is highly dependent on your exact architecture, but looking at the example above what you could do is:

  • Move everything in the if branch into a separate method
  • Move everything in the else branch into a separate method
  • Get rid of the hit_the_switch method alltogether
  • Make the decision what method to call in the initial caller of hit_the_switch

Feature Envy occurs when a code fragment references another object more often than it references itself, or when several clients do the same series of manipulations on a particular type of object.

Feature Envy reduces the code's ability to communicate intent: code that "belongs" on one class but which is located in another can be hard to find, and may upset the "System of Names" in the host class.

Feature Envy also affects the design's flexibility: A code fragment that is in the wrong class creates couplings that may not be natural within the application's domain, and creates a loss of cohesion in the unwilling host class.

Feature Envy often arises because it must manipulate other objects (usually its arguments) to get them into a useful form, and one force preventing them (the arguments) doing this themselves is that the common knowledge lives outside the arguments, or the arguments are of too basic a type to justify extending that type. Therefore there must be something which 'knows' about the contents or purposes of the arguments. That thing would have to be more than just a basic type, because the basic types are either containers which don't know about their contents, or they are single objects which can't capture their relationship with their fellows of the same type. So, this thing with the extra knowledge should be reified into a class, and the utility method will most likely belong there.

Example

Running Reek on:

class Warehouse
  def sale_price(item)
    (item.price - item.rebate) * @vat
  end
end

would report:

Warehouse#total_price refers to item more than self (FeatureEnvy)

since this:

(item.price - item.rebate)

belongs to the Item class, not the Warehouse.

OffersController#update has approx 6 statements

A method with Too Many Statements is any method that has a large number of lines.

Too Many Statements warns about any method that has more than 5 statements. Reek's smell detector for Too Many Statements counts +1 for every simple statement in a method and +1 for every statement within a control structure (if, else, case, when, for, while, until, begin, rescue) but it doesn't count the control structure itself.

So the following method would score +6 in Reek's statement-counting algorithm:

def parse(arg, argv, &error)
  if !(val = arg) and (argv.empty? or /\A-/ =~ (val = argv[0]))
    return nil, block, nil                                         # +1
  end
  opt = (val = parse_arg(val, &error))[1]                          # +2
  val = conv_arg(*val)                                             # +3
  if opt and !arg
    argv.shift                                                     # +4
  else
    val[0] = nil                                                   # +5
  end
  val                                                              # +6
end

(You might argue that the two assigments within the first @if@ should count as statements, and that perhaps the nested assignment should count as +2.)

Boolean Parameter is a special case of Control Couple, where a method parameter is defaulted to true or false. A Boolean Parameter effectively permits a method's caller to decide which execution path to take. This is a case of bad cohesion. You're creating a dependency between methods that is not really necessary, thus increasing coupling.

Example

Given

class Dummy
  def hit_the_switch(switch = true)
    if switch
      puts 'Hitting the switch'
      # do other things...
    else
      puts 'Not hitting the switch'
      # do other things...
    end
  end
end

Reek would emit the following warning:

test.rb -- 3 warnings:
  [1]:Dummy#hit_the_switch has boolean parameter 'switch' (BooleanParameter)
  [2]:Dummy#hit_the_switch is controlled by argument switch (ControlParameter)
