Question

What is the best approach to do this?

@user = UserFinder.find(first_name: "Dave")
if !@user
  return render :text => '// No user named Dave found'
end

if @user.last_name != "Edwards"
  # This is not the guy we want
  @user.destroy

  # Now we want to re-execute the search again forever until we find Dave Edwards
end

Keep in mind this is an incredibly simplistic example of the real code I have, so I know that I can just filter the query in the first place, but I want it this way.

I’m not sure how to do this with begin and while blocks because destroying an unwanted user is required if we run into one.

My Attempts:

---

begin
  @user = UserFinder.find(first_name: "Dave")
  return render :text => '// No user named Dave found'
end while @user.destroy if @user.last_name != "Edwards"

This doesn’t work because the while block gets the result of destroy not the comparison of last_name

P.S. Just if this is impossible this way, How to reload the Rails controller action with the same params?

Try this:

begin
  @user = UserFinder.find_by_first_name("Dave")
  render :text => '// No user named Dave found' if @user.nil?
  return if @user.nil?
end while @user.last_name != "Edwards" && @user.destroy
