Rails - 重定向到显示传递参数的页面

Question

我想从我的currencies控制器重定向到我的markets控制器，将当前货币作为参数（市场has_many种货币）传递。我想做这样的事情：

  redirect_to markets_show_url(id: @currency.market.id, currency: @currency)

如何正确完成？

Answer 1

在config / routes.rb中定义路由

例如

get "markets/:id" => "markets#show", as: :markets_show

在您的控制器中调用 redirect_to markets_show_url(id: @currency.market.id, currency: @currency.currency_name)

网址将

http://example.com/markets/your_id?currency=YOUR_CURRENCY

Answer 2

redirect_to market_url(@currency.market, currency_id: @currency.id)

在markets的控制器中： -

def show
  @market = Market.find(params[:id])
  @currency = Currency.find(params[:currency_id])
end

作为市场has_many货币，当前currency currency_id应作为参数传递，以便在market控制器show操作中获取当前货币
