I have been trying a lot for the last two days to implement a history feature for my basic wiki rails app. I am using papertrails for that. But according to my below code, whenever i click undo. it reverts back to the first edit instead of the last edit. does that means its not storing the last edit ? Any help please ?
pages_helper
module PagesHelper
def undo_link
link_to("undo", revert_version_path(@page.versions.last.reify ), :method => :post) end end
pages_controller
def revert @version = Version.find(params[:id]) if @version.reify @version.reify.save! else @version.item.destroy end
link_name = params[:redo] == "true" ? "undo" : "redo" link = view_context.link_to(link_name, revert_version_path(@version.next, :redo => !params[:redo]), :method => :post) redirect_to :back, :notice => "Undid #{@version.event}. #{link}" end
pages show.html.erb
<tbody> <% @page.versions.reverse.each do | version> %> <tr class="odd"> <td><input type="checkbox" /></td> <td><%= %></td> <td><%= version.created_at%></td> <td><%= undo_link %></td> <td><%= version.update_attributes :summary => 'version' %></td> </tr>
</div> <% end %>
routes
match "wikis/:wiki_id/pages/:id/revert" => 'pages#revert', :as => "revert_version"
Also, the route generated with this breaks when a new page is created under a wiki.
if there is some other tool. then i would like to know that which
would make this task easy
