如何将will_paginate方法添加到rails中的条件

This is the controller where I want the paginate method to be applied.

这是我希望应用paginate方法的控制器。

I need the paginate method next to `@products = Product.where(value: @type.value).paginate(page: params[:page]) #But this is not working.

我需要`@products = Product.where（value：@ type.value）.paginate（页面：params [：page]）旁边的paginate方法#But这不起作用。

Is there any way I can add the method without changing a lot of things.

有没有什么办法可以在不改变很多东西的情况下添加方法。

This is the Error I'm getting

The @product_types variable appears to be empty. Did you forget to pass the collection object for will_paginate?

@product_types变量似乎为空。你忘记了为will_paginate传递集合对象吗？

#will_paginate expects a collection as argument.

#will_paginate期望一个集合作为参数。

<%= will_paginate @products %>
