Hi, sorry to bother you with such question but how do you render a tree with a custom title field.... Let's says I want my Model field "name" to be the title of the nodes.

I tried many variations of:

%ol.sortable_tree.expandable{ data: {rebuild_url: rebuild_type_articles_url, expand_node_url: expand_node_type_articles_url } }
= expandable_tree @type_article, :title => :name

but each time I end up with a "undefined method `title' for #TypeArticle:0x000000058abce0" error.
Any help would be welcomed.
Thanks by advance.

For a project it would be great to have the sortable tree be closed and opened.

We implemented it with a little hack but now we need to change the jquery UI nested sortable file. You know this is not good, so I am wondering if the functionality could be added to the_sortable_tree

If you use a nested set make use of the possibility to fetch the whole tree in one query.
I saw you used the #children method to recursively fetch the whole tree, but fetching it using one #each_with_level call is much faster :)

hi,

wouldn't it be better to go with an ajax-capable js plugin?
http://www.jstree.com/
and implement it as ajax only (incremental)
i m not so sure if it s a good idea to load the complete tree.
we got performance problems for a big customer which had a lot of nodes.

when we by droping a node under another node in a tree, rebuild action gets called which save the position and render nothing and status ok.
This works fine as by droping of node it shown correcty on client and in rebuild it save the tree structure in database.
But if something breaks in rebuild action that is not notified to end user or drop is reverted.

So the tree structure on client and on server are not in sync

e.g. f.input as: the_sortable_tree

I think the 'klass =' line does not work properly here:
module TheSortableTreeController
...
module DefineVariablesMethod
public
def the_define_common_variables
...
--->> klass = self.respond_to?(:sortable_model) ? self.sortable_model : variable.classify.constantize # Recipe <<---

I have the 'Swxtodo::Todo' model class in my engine and this gives me only Todo. However I need Swxtodo::Todo. Changing to klass = self.class.to_s.sub(/Controller/,'').classify.constantize works for me, but I don't understand the respond_to part. Can you please fix the original code to work with engine's models as Swxtodo::Todo?
Thank you!

When I add sortable tree v1.5.0 to my Gemfile I get the following error:

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    the_sortable_tree (~> 1.5.0) ruby depends on
      rails (~> 3.1.0) ruby

    rails (3.2.1)

It depends on Rails 3.1.0.

When I add sortable tree without a specific version number to the Gemfile I get v1.4.8, which does work properly.

I want to do something after user drag/drop , is there any hooks I can use ?

thanks

My code looks like this:

%ol.sortable_tree{ data: { max_levels: 3, rebuild_url: rebuild_articles_url } }
  = sortable_tree @articles

Then I have a nice list with li elements with id="31_article" (31 as example).

When I sort it seems to work, but when I refresh it doesn't. It appears that the parameters [:next_id, :prev_id] are empty:

Started POST "/articles/rebuild" for 127.0.0.1 at 2013-09-11 16:34:45 +0200
Processing by ArticlesController#rebuild as JS

Any idea why?

I'm not sure my issue is with bootstrap, however, I can't seem to get the tree to render correctly or provide the drag and dropping capabilities in my rails app. Are there any known issues using Boostrap 3, Rails 4, and the latest sortable tree?

Here's what it currently looks like: https://www.evernote.com/shard/s24/sh/0d8083dd-4659-48c6-a711-d8e0e2300211/940049002148fb6bc8ac297c6e3d2822/res/6fa6413e-947f-4fe7-8987-bf9b6554d565/skitch.png

Thanks.

Hi,

Great gem but any chance to get html.erb versions for the partials ?

When I call the rebuild or move* methods the updated_at field is unchanged. It is not good because I watch the updated_at field to expire my cache.

Hello,

I'm using ERB but I can't really figure out how to convert the HAML code to something in ERB. I tried some stuff but it seems my rebuild path is used incorrectly. When I'm using the HAML code (the tree is a HAML partial, ugly as hell) it works.

So what is the erb alternative? (Maybe this should be added to the documentation)

Thanks!

Is there easy way to upgrade my sortable_tree from 1.9 ?
I have my /sortable/base/_link.html _node.html _controls.html etc in all my resources views where i use it. Now when i updated the_sortable_tree i have to remove all of them and use https://github.com/the-teacher/the_sortable_tree/blob/master/docs/How_to_create_new_tree_Render_Helper.md this approach ?

Hello,

I followed the read me, but i have this error :
SQLite3::SQLException: no such column: lft: SELECT id, nom, parent_id FROM "menus" ORDER BY lft ASC

I use rails 3.2, did i miss something ?

Thanks for your help.

I'm beginner with js so I want to show confirm dialog after drop item, if confirm ok => update tree else do nothing.
Please help me, thanks so much!

Hello.
Thanks for this good gem.

So lets go to the answer.
I have tree over than 5000 elements with many levels.
By default this gem renders all tree. Its not good in this case, 'cause slow.
And I did rendering by ajax next level when click on node.

I think it can be good if rendering by ajax will be part of gem.
Like

 sortable_tree ..., :ajax => true

If you interested I try to make pull request with this feature.

I do have a sortable tree set with in Admin namespace:

  def manage
    @pages = Admin::Page.nested_set.select('id, title, text, parent_id').all
  end

%ol.sortable_tree{ data: { max_levels: 5, rebuild_url: rebuild_admin_pages_url } }
  = build_server_tree @pages, :type => :sortable, :namespace => :admin

trace:

undefined method `admin_admin_page_path' for #<#<Class:0x007f8dc90e3068>:0x007f8dc90dff08>
Extracted source (around line #2):

1: %ol.sortable_tree{ data: { max_levels: 5, rebuild_url: rebuild_admin_pages_url } }
2:   = build_server_tree @pages, :type => :sortable, :namespace => :admin

It looks like it adds namespace to path twice.
Or is it just my error? I've tried your test app but this thing in admin namespace is not working either.

Found strange bug. My menu editing interface has address /admin/menus, it contains both editing form and 2 level sortable tree list. The editing form ends with Cancel/Save buttons like so:

<a class="btn btn-default" href="/admin/menus">Cancel</a> or <input class="btn btn-primary" name="commit" type="submit" value="Save" />

First time I visit this page, everythig looks fine, sortable tree drag&drop works like charm. But after I press Cancel, which leads me to the same URL where I just came from, nothing happens -- drag&drop is now broken until I press refresh or POST with Save.

After I installed https://github.com/kossnocorp/jquery.turbolinks the issue was gone, so I guess there's something related to the turbolink's javascript innitialization code.

Hi,

I forked your test app and added some HTML to _controls partial which breaks drag & drop functionality, please see following commit:
http://goo.gl/YciyB

Iit is causing an exception in jquery-ui.js:3856. The exeption message:
Uncaught TypeError: Cannot read property 'left' of null

Thanks,
Marek

Since Ruby 2.0, Object#respond_to? returns false for protected methods.
This will cause self.respond_to?(:sortable_collection) and self.respond_to?(:sortable_model) to return false, when true was expected. This case will happen when a namespaced controller overrides both methods sortable_model and sortable_collection.
The code can be replaced with self.methods.include?(:your_method). Let me know if you want me to send a pull request with the fixes.

the_sortable_tree looks really nice. What would it take to adapt it to ancestry (https://github.com/stefankroes/ancestry)?

Regards
Michael

I dont believe this is ready for rails 4. It looks like its generating non-digest assets within the CSS so the sort images are not rendering.

Do you know of a fix for this?

У меня есть mountable engine в котором используется the_sortable_tree.
В engine название модели содержит неймспейс, например MenuWithPages::MenuItem.
Похоже, поэтому и возникает ошибка при использовании в engine.

can the plugin support the feature ?

if it can't , can you tell me how to do it , I can make my branch .

There is typo in the_sortable_tree_controller.rb in expand_node function. There is

"return render(nothing: :true)" instead of "return render(nothing: true)"

Hello, in the README there is no info about using the expandable tree formatter.

Is this the only format that supports having a new_url, which I assume is for adding new entries on the sorting page?

Thanks in advance

drag node in unexpanded node
drops correctly
but target node doesnt expand anymore
only a refresh of the page helps

Здравствуйте. Хотелось бы использовать Ваш gem для управления категориями публикаций в блоге.

Возможно но ли ограничить создания детей не более третьего уровня?

То есть запретить перетягивание, например элемента первого уровня с дочерним элементом на третий(так как в итоге будет глубина 4)?

Hello,

I came across an issue and I thought I should report it. If you have a two-word model model (say ArticleCategory) the ajax rebuild url that will be generated will be 'articlecategories' when it should be 'article_categories' in order to work with the controller. The way to fix this is in the sortable tree helper and change

def define_class_of_elements_of tree
case
when tree.is_a?(ActiveRecord::Relation) then tree.name.to_s.downcase
when tree.empty? then nil
else tree.first.class.to_s.downcase
end
end

with

def define_class_of_elements_of tree
case
when tree.is_a?(ActiveRecord::Relation) then tree.name.to_s.underscore.downcase
when tree.empty? then nil
else tree.first.class.to_s.underscore.downcase
end
end


does it work already?

The tree renders fine. Adding new pages, deleting pages and moving pages to subtrees also works. However, sorting doesn't update anything. The output:

When I execute the above query in the console I get nil as result.

I don't know what could be the cause of this? I have attr_accessible :parent_id and attr_protected :lft, :rgt in Page.

Hi I'm writing a rails engine and added the_sortable_tree as a dependency.

My controller looks like this

However this throws error "uninitialized constant TheSortableTreeController"

Hi,

What a great gem...

It seems the depth column is ignored when the models are updated.
In the DB, depth stay NULL.

Hi,

very handy gem, works great for me - thanks!

In my application every user has a main page, which is the root for all pages for that particular user.
At the moment when I sort the tree I'm able to drag a child page of the root so it becomes sibling for the root - it's parent_id becomes nil.

I would like to prevent that. Any simple way to do it?

Thanks,
Marek

hi,

i always get 15 nodes only
but i want to show the complete tree.

i havnt set any limits?

is this a bug?

Drag & Drop in the "sortable tree" doesn't works with the suggested options:

%ol.sortable_tree{ data: { max_levels: 5, rebuild_url: rebuild_pages_url } }
  = sortable_tree @pages

The problem is that HAML copiles

%ol.sortable_tree{ data: { max_levels: 3, rebuild_url: "something" } }

to

<ol class='sortable_tree' data-max-levels='3' data-rebuild-url='something'></ol>

Based on this HTML the next 2 lines in the javascript

    rebuild_url   = sortable_tree.data('rebuild_url')
    max_levels    = sortable_tree.data('max_levels')

don't get anything, because the in the DOM the dataset contains always the camelCase version of the attributes, i.e. 'rebuildUrl' and 'maxLevels'. So I changed the 2 line to

    rebuild_url   = sortable_tree.data('rebuildUrl')
    max_levels    = sortable_tree.data('maxLevels')

and IT WORKS!!!

Please, tell me, if I'm wrong. You should update the gem.

BTW: Thanks for this gem, great work.

Tibor

Thanks in advance!

When I try to move an element I get this error:
Uncaught TypeError: Object # has no method 'rebuild'

The error is coming from this line:

https://github.com/the-teacher/the_sortable_tree/blob/master/app/assets/javascripts/sortable/base.js.coffee#L28

I'm don't have a lot of time to dig in now. I do know that window.sortable.rebuild() exists, but it doesn't seem like rebuild is getting on the object that the above line is expecting. It may be a coffeescript scoping issue with -> vs => ?

We have multiple companies that have a sortable tree. However, when we sort the tree inside one company, it doesn't take into account the scope of the company, thus mixing every page and messing everything up :(

I've had a problem with my controller tests beeing extremely slow. Only two simple tests had an average run time of 200s. I managed to track the issue to the just_tree method, which I use to render my main menu. When I removed the call to just_tree, the run time of the tests dropped from 200s to 0.4s.

The weird thing is that browsing the site isn't particularly slow, just the tests.
I'm using Test::Unit by the way.
