refactoring 2 controllers into a log controller

CigaretteLogController.js

    this.CURRENTLY_SMOKING = 'currently_smoking';
    this.SMOKING_REASON = 'smoking_reason';
    this.URGE_STRENGTH = 'urge_strength';
    this.SMOKING_REASONS = ['Reduce craving',
                            'Soon going where I can’t smoke',
                            'Cope with negative emotion',
                            'Enhance positive emotion',
                            'Habit/automatic',
                            'Opportunity to socialize',
                            'Break from work/studying',
                            'Boredom/to kill time',
                            'other'];

    this.STATE_TIMING = 'timing';
    this.STATE_REASON = 'reason';
    this.STATE_URGE = 'urge';
    this.STATE_FINAL = 'final';

    // Initizalization state
    this.state = this.STATE_TIMING;
    this.cigaretteLog = {};

    this.getCurrentlySmoking = function() {
      return this.cigaretteLog[this.CURRENTLY_SMOKING];
    };

    this.saveCigaretteLog = function() {
      cigaretteLogService.saveCigaretteLog(this.cigaretteLog);
      this.cigaretteLog = {};
      $location.url(Routes.HOME);
    };

    this.setTiming = function(currentlySmoking) {
      this.cigaretteLog[this.CURRENTLY_SMOKING] = currentlySmoking;
      this.state = this.STATE_REASON;
    };

    this.setState = function(newState) {
      this.state = newState;
    }
  }

// becomes...
    this.CURRENTLY_SMOKING = 'currently_smoking';
    this.SMOKING_REASON = 'smoking_reason';
    this.STATE_INITIAL = 'timing';

    this.getCurrentlySmoking = function() {
      return this._getLog([this.CURRENTLY_SMOKING]);
    };

    this.saveLog = function() {
      cigaretteLogService.saveCigaretteLog(this._getLog());
    };

    this.setTiming = function(currentlySmoking) {
      this._setLog([this.CURRENTLY_SMOKING], currentlySmoking);
      this.state = this.STATE_REASON;
    };
  }

LogController.js

  // prototype methods on abstract LogController
    this.STATE_FINAL = 'final';
    this.STATE_REASON = 'reason';
    this.URGE_STRENGTH = 'urge_strength';
    this.STATE_URGE = 'urge';
    this.REASONS = ['Reduce craving',
      'Soon going where I can’t smoke',
      'Cope with negative emotion',
      'Enhance positive emotion',
      'Habit/automatic',
      'Opportunity to socialize',
      'Break from work/studying',
      'Boredom/to kill time',
      'other'];

    this.initialize = function() {
      this.state = this._getInitialState();
      this._resetLog();
    }

    this.saveLog = function() {
      throw Error(message: 'saveLog must be defined');
    };
    this.save = function() {
      this.saveLog();
      resetLog();
      $location.url(Routes.HOME);
    };

    this.setState = function(nextState) {
      this.state = nextState;
    };
    
    function _getInitialState() {
      if (this.INITIAL_STATE) {
        return this.INITIAL_STATE;
      } else {
        throw Error(message: "INTIAL_STATE constant must be defined"); // this.STATE_TIMING or this.STATE_REASON
      }
    };
    
    function _getLog(key) {
      return this.log[key];
    };
  
    function _resetLog() {
      this.log = {}
    };
  
    function _setLog(key, value) {
      this.log[key] = 'value'
    };

    this.initialize();

TemptationLogController.js

    this.TEMPTATION_REASON = 'temptation_reason';
    this.URGE_STRENGTH = 'urge_strength';
    this.TEMPTATION_REASONS = ['Reduce craving',
      'Soon going where I can’t smoke',
      'Cope with negative emotion',
      'Enhance positive emotion',
      'Habit/automatic',
      'Opportunity to socialize',
      'Break from work/studying',
      'Boredom/to kill time',
      'other'];
    this.STATE_REASON = 'reason';
    this.STATE_URGE = 'urge';
    this.STATE_FINAL = 'final';

    // Initizalization state
    this.state = this.STATE_REASON;
    this.temptationLog = {};

    this.saveTemptationLog = function() {
      temptationLogService.saveTemptationLog(this.temptationLog);
      this.temptationLog = {};
      $location.url(Routes.HOME);
    };

    this.setState = function(nextState) {
      this.state = nextState;
    };
// becomes...
    this.STATE_INITIAL = 'timing'; 
    this.TEMPTATION_REASON = 'temptation_reason';

    this.saveLog = function() {
      temptationLogService.saveTemptationLog(this.temptationLog);
    };

Then instead of saveCigaretteLog you call save
