will-paginate

问题 I am following the "Pagination with ajax" railscast for my rails 3 application. Everything seems to work great, except the fact that Previous and next links don't work at all. Basically, It appears that the previous link is stuck even if I click on other pages, (when I am on the user/show page1) The "next link" works one time till the page 2 (I can't use it after) Numbers didn't update when I come to "..." I would be pleased to know if someone experience the same problem (a bug?) or if my

问题 I have 8 controllers using will_paginate to paginate their index pages. I'd like to override the defaults for "Previous" and "Next" on each without having to specify the same options 8 times. Is there a way to override the defaults only once (perhaps by subclassing will_paginate). 回答1: will_paginate uses I18n so you can just use that. Given you use English as the default locale the following line should be present in application.rb : config.i18n.default_locale = :en you can then change the

问题 I get DEPRECATION WARNING: #apply_finder_options is deprecated. when trying this in my user.rb : def User.search(search, page) paginate page: page, per_page: 10, conditions: ['name LIKE ?', "%#{search}%"], order: 'name' end Called through UsersController : def index @users = User.search(params[:search], params[:page]) end The pagination is done with the will_paginate gem. What is triggering the warning and how can I fix it? Been trying some googling, but I find the docs not too comprehensive!

问题 I've got a custom will_paginate renderer that overrides WillPaginate::ViewHelpers::LinkRenderer's link method like so: def link(text, target, attributes = {}) "<a href='/users/95/friends_widget?page=#{target}' rel='next' data-remote='true'>#{text}</a>" end ...and that works great, except you can see the hard-coded 95 in that link. How would I pass a parameter (e.g. user or user's ID) into the custom renderer via the Rails view? <%= will_paginate(@user_friends, :remote => true, :renderer =>

问题 Newly installed will_paginate 3.0.0 gem 'will_paginate', '~> 3.0.0', :require=>'will_paginate/data_mapper' Running a controller query: @tickets = Ticket.paginate(:page => params[:page], :per_page => 5,:username => @ticket.username) Which works, pulls up all the tickets for a user and paginates in 5's if I put ?page=X where x is a page number in the url. =will_paginate(@tickets) in the view does not work, this results in undefined method `will_paginate' for #<#<Class:0x000000053674c8>

问题 I have some photos that are split on successive pages through will_paginate plugin. When you open a photo and then return to all photos using a link, you always return to the first page (e.g. the photo is displayed on page 5, you open the photo, click a link to show all photos and expect that you are on page 5 again, but you are on page 1). Now, is there any method to get the page number to which a photo belongs to? I tried to pass a GET parameter, but this only works if the user doesn't

问题 I am following this railscast in trying to implement an infinite scroll page on my rails app. When a user scrolls down to the bottom of the page an new set of items is appended and the page extends, however it is appended to the page multiple times and the event triggers again on scrolldown even when all the items in the array have been loaded, appending the same set of items again multiple times. What I would like is to append the 'next page' of items each time a user scrolls to the bottom,
