Render multilpe times - Double render in rails

Question

How to avoid this double render issue, i have been trying to replicate but couldn't. So is there any issue with this below code?

def check_count
  assign_values_from_params
  if count >= failed_count
    render partial: params[:view_name], layout: false and return
  else
    render text: 'works' and return
  end
end


def assign_values_from_params
  # code
  # code
  # code
  if @date.blank?
    redirect_to main_index_path and return
  end

  if @counted_obj != 5
    # call one function
  end
end

Also should i try something this way Double render error rails ?

Answer 1

Call performed? to check if render or redirect has already been called.

You might want to change your to code to something like this:

def check_count
  assign_values_from_params
  
  return if performed?

  if count >= failed_count
    render(partial: params[:view_name], layout: false)
  else
    render(text: 'works')
  end
end

def assign_values_from_params
  # code

  if @date.blank?
    redirect_to(main_index_path) and return
  end

  # code
end
