Rails create form submitting multiple times

I have a rails form calling upon the create function in my controller, and I've noticed if i press the submit button multiple times while the page loads, I am able to submit the form multiple times. Is there a way to prevent this from happening? My button is:

<%= button_to edit_production_path(id: current_user.default_working_production_id), class: "btn btn-default navbar-btn", :method => :get do %><span class="glyphicon glyphicon-film"></span>&nbsp; Production Settings<% end %>

And my controller is:

def create
    @production = Production.new(production_params)
    @production.user = current_user
    @production.user_name = current_user.name

    if @production.save
        redirect_to productions_path
    else
        render 'new'
    end
end`
