Ruby on Rails：实现查询大量数据的最佳方法

Question

I'm creating an application that is very heavy in data, almost like an inventory system. In index, I had to query/load a big amount of data, and inside my controller, I have this code.

@vehicles = Vehicle.all

@vehicles will all be listed in the corresponding view.

At first, this was not a problem because the number of vehicles was just around hundreds. But as the vehicle's number increases, the application becomes very slow.

What is the best way to implement this kind of scenario in RoR?

Answer 1

Have you considered pagination? Because even if the DB is fast and instandly returns your data, the view/html will be so long, that rendering will take very long
