Question

I am doing

if params[:type] = "Type A"
   # do something
end
if params[:type] = "Type B"
   # do something
end

But I think that is wrong. I should be using ==

However that gives me error:

You have nil object when you didn’t expect it

What is the best way to do this in rails?

All I am doing is getting a radio button variable from a form and doing logic based on its value (either Type A or Type B)

Answer 1

Preamble

class Hash
  def try(arg)
    self[arg] rescue nil
  end
end

Your way

if params.try(:type) == "Type A"
    # do
elsif params.try(:type) == "Type B"
    # do
end

DRY

case params.try(:type)
when "Type A"
    # do
when "Type B"
    # do
else
    # default do
end
