Message-ID: <45e5e9bc0801141442y4b667efco2a256ba6a5e1b39a@mail.gmail.com>

Hi All,

I'm having trouble configuring a table to be able to accommodate multiple
trees.
I have a feeling that this is a common question but a few creative searches
came up empty.
I tried using http://wiki.rubyonrails.org/rails/pages/BetterNestedSet as a
guide and created
a tree_id column in my table and used  acts_as_nested_set, :scope =>
:tree_id in my model.

My rspec tests began failing and reporting the MYSQL error below:

*Mysql::Error: #42000You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near '? ? "tree_id IS NULL" : "tree_id = #{tree_id}" AND
(parent_id IS NULL))  ORDER B' at line 1: SELECT * FROM studies WHERE
(tree_id.nil? ? "tree_id IS NULL" : "tree_id = #{tree_id}" AND
(parent_id IS NULL))  ORDER BY lft
*
Any insight is greatly appreciated.  I guess I'm a bit hazy on what :scope
is used for and how to use it.
I've also played around with making multiple trees without :scope in my
directive and it most of my method calls
ended up looking like I'd expect.  (.root? and .root got weird on me)

-Thanks!
Stephen

Hi Stephen,

You need to populate the tree_id column for every record. Then things
should be fine-- let us know if they aren't.

Hi Krishna,

Thanks for the quick reply!  I still get a MySQL error.
My class looks like:

class Study < ActiveRecord::Base
  acts_as_nested_set :scope => :tree_id
  ...
end

Here's a snippit from a (typically frustrating) script/console session using
an empty table:

>> s1 = Study.new(:name=>'Grandpa', :oid=>123,:tree_id=>1)
=> #<Study:0x23f7814 @new_record=true, @attributes={"name"=>"Grandpa",
"updated_at"=>nil, "lock_version"=>0, "lft"=>nil, "tree_id"=>1,
"parent_id"=>nil, "rgt"=>nil, "oid"=>123, "created_at"=>nil}>

>> s1.valid?
=> true

>> s1.save
ActiveRecord::StatementInvalid: Mysql::Error: #42000You have an error in
your SQL syntax; check the manual that corresponds to your MySQL server
version for the right syntax to use near '? ? "tree_id IS NULL" : "tree_id =
#{tree_id}")' at line 1: SELECT max(rgt) AS max_rgt FROM studies WHERE
(tree_id.nil? ? "tree_id IS NULL" : "tree_id = #{tree_id}")

-Thanks again,
Stephen

Sorry for the double-email but I was looking line 79 of
better_nested_set.rb:
 options[:scope] = %(#{options[:scope].to_s}.nil? ? "#{options[:scope].to_s}
IS NULL" :
 "#{options[:scope].to_s} = \#{#{options[:scope].to_s}}")

This sets options[:scope] to be a string of ruby code, rather than SQL.
For instance, if options[:scope] was :tree_id, the above would evaluate
to:

'tree_id.nil? ? "tree_id IS NULL" : "tree_id = #{tree_id}"'

And this string is then put into acts_as_nested_set_options on line 88.

UPDATE:

Thanks for the help on this Krishna.  I think my project was using an old or
self-hacked version of the plugin.
I've reinstalled it and all seems well.

hmmm, I am having this exact problem with the latest BNS on Rails 2.02.

Should this work on 2.02? It appears as though AR isn't interpolating
strings the way it used to.

Subject: [Betternestedset-talk] move_to_child_of() on existing records.
Message-ID: <45e5e9bc0801301444n377d57e0vac75e3615e74ca40@mail.gmail.com>

Hey all,

I have a quick question about some weirdo behavior I'm seeing in my tables.
I have a table that looks like:

ID     NAME     LFT     RGT     PARENT_ID     TREE_ID
18     dogs        1         2          null                  18
19     cats         1         4          null                  19
20     smalldogs 2        3          19                    19

and say to myself 'oops' - smalldogs is really a child of 'dogs.' - not cats
opening up a script/console session I play around with the records...

>> t = Team.find(20)
=> #<Team id: 20, name: "Small Dogs", lft: 2, rgt: 3, parent_id: 19,
tree_id: 19>
>> t.tree_id = 18
=> 18
>> t.save
=> true
>> t.move_to_child_of(Team.find(18))
=> nil

My table ends up looking like
ID     NAME     LFT     RGT     PARENT_ID     TREE_ID
18     dogs        1         2          null                  18
19     cats         1         4          null                  19
20     smalldogs 2        3          19                    18

So it's a little weird that smalldog.parent_id and dogs.lft/rgt weren't
adjusted after calling move_to_child_of.
So - is there a common pattern for moving existing nodes into other trees
when using the scope option?

Thanks!
-Stephen

Hi Stephen,

Currently the API does not support moving nodes between trees.

You may want to make sure you are using the trunk version of the code
since I vaguely recall putting a check in there that would raise if
you tried to move nodes between trees. Or maybe I just imagined it.

Hi Krishna,

Thanks so much for the quick response - I really appreciate it.
I'll take double check that I've got the latest and greatest.
(I may be using a version from /tags/stable).

-Stephen
