Thanks. 回答1: I fixed this problem by specifying gem version

Rails 2 to Rails 3 : using link_to instead of link_to_remote (including remote and update)

由 99封情书 提交于 2019-12-28 06:23:45
问题 A quick and easy answer I'm sure. I'm upgrading a Rails project from version 2 to version 3 and replacing a load of the link_to_remote with link_to's as per the Rails 3 update. Even something as simple as : <%= link_to "Check Time", {:action=>:get_time}, :remote=>true, :update=>'current_time' %> <div id='current_time'></div> doesn't seem to work. The request (using get method) is going through ok and the rendered html is : <a href="/monitoring/get_time" data-remote="true" update="current_time

问题 I am using Ruby 1.9.2, Rails 3.0.4/3.0.5 and Phusion Passenger 3.0.3/3.0.4. My templates are written in HAML and I am using the MySQL2 gem. I have a controller action that when passed a parameter that has a special character, like an umlaut, gives me the following error: ActionView::Template::Error (incompatible character encodings: UTF-8 and ASCII-8BIT) The error points to the first line of my HAML template, which has the following code on it: <!DOCTYPE html> My understanding is that this is

:as in rails routes.rb

问题 In config/routes.rb , I tried both: root :to => 'things#index', :as => 'things' and root :to => 'things#index' When I hit http://localhost:3000/ , both approaches work, and nothing seems to be different. What is the :as option used for? 回答1: The :as option forms a named route. Usually it's used in a non-root route. For example: match '/search' => 'search#search', :as => 'search' # SearchController#search You could then do something like: <%= link_to search_path, 'Click Here to Search!' %>

Rails: how can I get unique values from column

问题 How can I get unique values from column in the table? For example, I have this Products table: ID NAME CATEGORY 1 name1 1st_cat 2 name2 2nd_cat 3 name3 1st_cat Here I want to get only 2 values - 1st_cat and 2nd_cat: <%Products.each do |p|%> <%=p.category%> <%end%> 回答1: Two more ways: Product.select(:category).map(&:category).uniq Product.uniq.pluck(:category) For Rails >= 5.1 use: Product.distinct.pluck(:category) 回答2: I think you can do this: <% Products.select("DISTINCT(CATEGORY)").each do
