What is the best way to do this?

I have this in a view `<%= badges(challenge) %>` or `<%= challenge.badges %>` depending on if I put `badges` in a helper or the model.

I was told to put it in a helper. I put it in so like this:

```
module ChallengesHelper
  def badges(challenge)
    if challenge.name == "Read 20 Min"
      ActionController::Base.helpers.image_tag("read.png", class: "gold-star")
    elsif challenge.name == "Exercise 20 Min"
      ActionController::Base.helpers.image_tag("exercise.png", class: "gold-star")
    elsif challenge.name == "Meditate 10 Min"
      ActionController::Base.helpers.image_tag("meditate.png", class: "gold-star")
    elsif challenge.name == "Stretch 5 Min"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Write 500 Words"
      ActionController::Base.helpers.image_tag("write.png", class: "gold-star")
    elsif challenge.name == "Walk 5,000 Steps"
      ActionController::Base.helpers.image_tag("walk.png", class: "gold-star")
    elsif challenge.name == "Eat Fruit & Veg"
      ActionController::Base.helpers.image_tag("fruit-and-vegetable.png", class: "gold-star")
    elsif challenge.name == "Plan Day"
      ActionController::Base.helpers.image_tag("plan.png", class: "gold-star")
    elsif challenge.name == "After Waking, Guzzle Water"
      ActionController::Base.helpers.image_tag("water.png", class: "gold-star")
    elsif challenge.name == "Track Food Consumption"
      ActionController::Base.helpers.image_tag("track-food.png", class: "gold-star")
    elsif challenge.name == "Random Act of Kindness"
      ActionController::Base.helpers.image_tag("random-kindness.png", class: "gold-star")
    elsif challenge.name == "Write 3 Gratitudes"
      ActionController::Base.helpers.image_tag("gratitude.png", class: "gold-star")
    elsif challenge.name == "Juice Fast"
      ActionController::Base.helpers.image_tag("juice.png", class: "gold-star")
    elsif challenge.name == "Not Smoke"
      ActionController::Base.helpers.image_tag("not-smoke.png", class: "gold-star")
    elsif challenge.name == "Not Drink Alcohol"
      ActionController::Base.helpers.image_tag("not-drink.png", class: "gold-star")
    # GOAL CHALLENGES
    elsif challenge.name == "Live Abroad"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Long Road Trip"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Tour Capital Building"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Karaoke"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "See New York Skyline"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Run 5K"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Write Memoir"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Lose 10 Pounds"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Join Club"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Skydive"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Start a Blog"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Donate $100 to Charity"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Create Independent Income Stream"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Paint a Picture"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif challenge.name == "Give a Public Speech"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    else
      ActionController::Base.helpers.image_tag("gold-star-maze.png", class: "gold-star")
    end
  end
end

```

I'm only concerned because it seems more "wordy" in the helper than the model.

```
  def badges
    if name == "Read 20 Min"
      ActionController::Base.helpers.image_tag("read.png", class: "gold-star")
    elsif name == "Exercise 20 Min"
      ActionController::Base.helpers.image_tag("exercise.png", class: "gold-star")
    elsif name == "Meditate 10 Min"
      ActionController::Base.helpers.image_tag("meditate.png", class: "gold-star")
    elsif name == "Stretch 5 Min"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Write 500 Words"
      ActionController::Base.helpers.image_tag("write.png", class: "gold-star")
    elsif name == "Walk 5,000 Steps"
      ActionController::Base.helpers.image_tag("walk.png", class: "gold-star")
    elsif name == "Eat Fruit & Veg"
      ActionController::Base.helpers.image_tag("fruit-and-vegetable.png", class: "gold-star")
    elsif name == "Plan Day"
      ActionController::Base.helpers.image_tag("plan.png", class: "gold-star")
    elsif name == "After Waking, Guzzle Water"
      ActionController::Base.helpers.image_tag("water.png", class: "gold-star")
    elsif name == "Track Food Consumption"
      ActionController::Base.helpers.image_tag("track-food.png", class: "gold-star")

    elsif name == "Write 3 Gratitudes"
      ActionController::Base.helpers.image_tag("gratitude.png", class: "gold-star")
    elsif name == "Juice Fast"
      ActionController::Base.helpers.image_tag("juice.png", class: "gold-star")
    elsif name == "Not Smoke"
      ActionController::Base.helpers.image_tag("not-smoke.png", class: "gold-star")
    elsif name == "Not Drink Alcohol"
      ActionController::Base.helpers.image_tag("not-drink.png", class: "gold-star")
    # GOAL CHALLENGES

    elsif name == "See New York Skyline"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Run 5K"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Write Memoir"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Lose 10 Pounds"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Join Club"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Skydive"

    elsif name == "Start a Blog"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Donate $100 to Charity"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Create Independent Income Stream"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Paint a Picture"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    elsif name == "Give a Public Speech"
      ActionController::Base.helpers.image_tag("stretch.png", class: "gold-star")
    else
      ActionController::Base.helpers.image_tag("gold-star-maze.png", class: "gold-star")
    end
  end

```

Why is one spot better than the other? And what is the best practice for something like this where their are a lot of string conditions?
