如何将旧url重定向到rails app中新的friendly_id生成的url？
我使用friendy_id来friendy_id我的url。 我使用的旧url如下所示：
localhost:3000/search?category_id=208
现在它看起来像这样：
localhost:3000/search?category_id=metal-processing-and-machine-tool
我的控制器是这样的：
def search_equipments begin if (params.keys & ['category_id', 'sub_category', 'manufacturer', 'country', 'state', 'keyword']).present? if params[:category_id].present? @category = Category.active.friendly.find_by_friendly_id params[:category_id] else @category = Category.active.friendly.find_by_friendly_id params[:sub_category] if params[:sub_category].present? end @root_categories = Category.active.roots @sub_categories = @category.children.active if params[:category_id].present? @sub_categories ||= {} @countries = Country.active.all @manufacturers = Manufacturer.active.all @states = State.active.where("country_id = ?", params[:country]) if params[:country].present? @states ||= {} unless params[:category_id].present? && params[:sub_category].present? params[:category_id] = @category.id if params[:category_id].present? params[:sub_category] = @category.id if params[:sub_category].present? end @equipments = Equipment.active.filter(params.slice(:manufacturer, :country, :state, :category_id, :sub_category, :keyword)).order("#{sort_column} #{sort_direction}, created_at desc").page(params[:page]).per(per_page_items) else redirect_to root_path end rescue Exception => e render :file=>"#{Rails.root}/public/404.html",:status=>404 end end
现在我正在将旧url重定向到404页面。 但相反，我希望旧url重定向到新url。 我怎样才能做到这一点？ 我经历了一些解决方案。 但我的大控制器方法使其足够复杂以遵循这些解决方案。
你可以试试这个：
if params[:category_id].present? and params[:category_id].to_s !~ /\D/ category = Category.find_by_id(params[:category_id]) return redirect_to search_equipments_path(request.query_parameters.merge(category_id: category.name.parameterize)) if category.present?
如果您有子类别，则可以使用相同的条件只将params category更改为sub-category 。
将此添加到您的方法search_equipments开头
if params[:category_id].present? and params[:category_id].to_s !~ /\D/ category = Category.find_by_id(params[:category_id]) return redirect_to search_equipments_path(category_id: category.name.parameterize) if category.present? end
