レールのチュートリアルに続いて、method: :delete
アクションを試行したときにこのエラーが発生します。レールがSQLite localhostをHerokuに移植しないPGSQL
ActiveRecord::StatementInvalid (PG::DatatypeMismatch: ERROR: argument of WHERE must be type boolean, not type integer
これは私の破壊方法です。
def destroy
@user_stock = current_user.user_stocks.where(stock_id: params[:id]).first
@user_stock.destroy
respond_to do |format|
format.html { redirect_to my_portfolio_path, notice: "#{@user_stock.stock.ticker} was removed from portfolio." }
format.json { head :no_content }
end
end
私は右に使用する必要がhereについてfind
とfind_by
上の質問を読んで、それはちょうど私を混乱。
