Render multilpe times - Double render in rails

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

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

Remove the return statement from render partial: params[:view_name], layout: false and return as after render it will lead to return nil. Remove the return statement from both lines and it should be fixed.

It should look something like this render text: 'works'.

According to me first, check whether any render is being called. As going through your code it is not showing but maybe internally it is being called. So You can call performed? in your controller to check if render was already called:

performed?               # => false
render partial: params[:view_name], layout: false
performed?               # => true 

If calling performed? says true for the first time then you have to check your code.

Using return after render will return nil so i suggest you to remove return from both render , which should look like this. if tmp_count >= failed_count render partial: params[:view_name], layout: false else render text: 'works' end

Hope this works for you.

Try this and see if it works for you.

def check_count
  assign_values_from_params

end


def assign_values_from_params
  # code
  # code
  # code
  if @date.blank?
    redirect_to main_index_path and return
  else
    if @counted_obj != 5
      # call one function
    end

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

end
