问题 I'm having difficulty customizing the default kaminari template. I've used the generator to create kaminari template files. In kaminari/paginator.html.haml: = paginator.render do %nav.pagination All I want to do is access the actionview helpers within this, like link_to, or render. I've searched the source code and I can't find any incline of the helper being passed to this render method. Essentially, being able to do this: = paginator.render do %nav.pagination = render :partial => 'custom

问题 I need to implement some logic for to show 3 elements on the first page and by 1 element on all the next. For the first page there is no problems: items = @model.limit(@first_page_items) and for all the next ones i tried: @model.offset(@first_page_items).page(@current_page - 1).per(@per) #makes no offset at all - all the items going from the beginning @model.page(@current_page - 1).per(@per).offset(@first_page_items) #produces 4-th element on the second page and stays on it for ever What am I

问题 This question already has answers here : How do I speed up counting rows in a PostgreSQL table? (6 answers) Closed 5 years ago . I'm using the Kaminari gem to paginate a query on a large table (~1.5MM rows). While fetching the actual results pages is quite quick (~20ms), kaminari's added SELECT COUNT(*) WHERE .... is excruciatingly slow, and adds several extra seconds to the execution time. Is there a way to approximate the number of results instead? 回答1: Quick estimate for whole table For a

问题 While using kaminari, I got an error. Gemfile: # gem 'will_paginate', '~> 3.0.6' # gem 'will_paginate-bootstrap' gem 'kaminari' lists_controller.rb def index if params[:tag] @lists = List.tagged_with(params[:tag]).order(created_at: :desc).paginate(page:params[:page], per_page: 3 ) else @lists = List.all.order(created_at: :desc) end end I also user .page params[:page].per(2) follow .order(created_at: :desc) but not work views/lists/index.html.erb <%= paginate @lists %> the error is here

问题 I updated my Rails 3.0.7 application to use kaminari 0.12.4 (up from 0.10.4) for pagination and jquery-rails 1.0.9 and it seemed to break pagination. I've regenerated the kaminari views since they are different but for some reason ajax isn't working. <%= javascript_include_tag :defaults %> is included. Which produces this in the browser: <script src="/javascripts/jquery.js?1306353646" type="text/javascript"></script> <script src="/javascripts/jquery-ui.js?1306368501" type="text/javascript"><

问题 I've set up action caching (with sweepers, but I guess that's irrelevant here) in my app, and so far it works great except for one thing: I use Kaminari for pagination, and thus when I execute expire_action on my action it only expires the first page. As I know caching won't work when using the query string for specifying the page, I've set up a route so the pages are appended to the end of the url (for example /people/123/page/2). I'll add more info to this post if necessary, but I'm

问题 I'm not sure what I did, but kaminari has started acting weird in my app. In my controller: @producers = Producer.order(:name).page(params[:page]) view: <%= paginate @producers %> results in: undefined method `num_pages' for #<ActiveRecord::Relation:0x000001026e6308> If I add .per in my controller: @producers = Producer.order(:name).page(params[:page]).per(25) I get undefined local variable or method `per' for #<ActiveRecord::Relation:0x0000010928ef60> Finally, strangely, if I move my .order(

问题 I was implementing a chat system to my app, in which only the list of comments will be reloaded with ajax submit. Kaminari pagination is used in there, but it gets weird string in its url like this after new comment was submit. example-website.com/users/mike/refresh_part?_=1356906069855&page=2 and it gets more strange argument parameters in its url when comment was submit in the other controller. Only when it was macthed with spamming error Generated url: example-website.com/shop/walmart
