I am creating Rails API and when I do get request to mywebsite.com/posts/all it shows me all the post data. I am trying to do mywebsite.com/posts/all?limit=20 to show 20 results or some other number. What is the way to achieve it with rails?

Easy way for this is

@posts = Post.limit(params[:limit])

But you could also use will_paginate gem

Limit will not work, each time if u call this method it will return only last 20 records, Best way to achieve this result using pagination, here you can limit number record passing when each request is hitting

You can use gem will_paginate

In controller

@posts = Post.paginate(:page => params[:page], :per_page => 20)

In the view

<%= will_paginate @posts %>

For info about will_paginate https://github.com/mislav/will_paginate/blob/master/README.md

If u r using API pass params ass below

GET /v1/posts?page=1&per_page=10

Change value in controller

@posts = Post.paginate(page: params[:page], per_page: params[:per_page])
