Rails / Kaminari - How to order a paginated array?

由 守給你的承諾、 提交于 2019-12-11 09:16:16
问题 I'm having a problem ordering an array that I've successfully paginated with Kaminari. In my controller I have: @things = @friend_things + @user_things @results = Kaminari.paginate_array(@things).page(params[:page]).per(20) I want to have the final @results array ordered by :created_at , but have had no luck getting ordering to work with the generic array wrapper that Kaminari provides. Is there a way to set the order in the Kaminari wrapper? Otherwise what would be the best way? Thanks. 回答1:

问题 I've tried to use this tutorial Kaminari endless page and also watched Ryan Bates episode #114 Endless Page (revised) and tried to implement an infinite scrolling functionality to my online store. I don't know for sure how to apply the products rendering in my index.js.erb file because it's quite different implemented in the Spree. I've also forgot to mention that I'm quite new to the Spree platform. All I've been doing so far was changing these files: views/spree/products/index.html <%

Kaminari generates string instead of html

由 若如初见. 提交于 2019-12-10 10:54:15
问题 There was question like this in november, but no anwers was given. Kaminari generates string instead of html in production And no feedback from author, lack of reputation does not give me the opportunity to ask question there, also my problem a little bit different too. I'm using Rails 4.2.4, Kaminari 0.16.3 and slim as my template language. The pagination navigation is generated correctly, but = paginate @articles generates ALMOST a string instead of html. So it's escape tags and show them

How to set different page size for the first page in Kaminari?

由 只谈情不闲聊 提交于 2019-12-10 09:25:03
问题 I have a number of objects I would like to paginate using Kaminari. However, on the first page I would also like to show a notification allowing the viewer to create his own object, reducing the number of objects that can be displayed on that page. However, the indicated number of pages should also take into account that this first page contains less elements. Let's say the objects are the letters a through z. The first page should only 4 display letters: {a,b,c,d} , while all other pages

Kaminari & Rails pagination - undefined method `current_page'

问题 I searched and searched, but nothing solved my problem. Here's my controller: def show @topic = Topic.find(params[:id]) @topic.posts = @topic.posts.page(params[:page]).per(2) # 2 for debugging end That functions just fine, because the topic view is reduced to two posts. However, when I add this to show.html.erb: <%= paginate @topic.posts %> I'm given this error: undefined method `current_page' for #<ActiveRecord::Relation:0x69041c9b2d58> 回答1: Try with: def show @topic = Topic.find(params[:id]
