Project columns 'lft' and 'rgt' empty after migration 104
Added by Andreas Hartmann over 15 years ago
Hi everybody,
I just upgraded my Redmine installation. Migration 104 (104_add_projects_lft_and_rgt.rb) created new project columns 'lft' and 'rgt', but since they are empty, various exceptions are thrown when I try to access the Redmine application.
Do I have to insert values into these columns manually? What do they mean?
Thanks a lot for any hints!

I assume the values should have been set in migration 105, but apparently this has not happened. Here's the output of the migration:
105 BuildProjectsTree: migrating =========================================105 BuildProjectsTree: migrated (0.2385s) ================================
None of the column values for 'lrt' and 'rgt' of my projects table has been set.

Apparently migration 105 failed, probably because a PATH problem in my setup. I invoked Projects.rebuild! from the Ruby CLI, it worked and inserted the missing values.
Sorry for the noise.

I just replayed the migration back and forth, but Projects.rebuild! just isn't executed – it works only from the CLI. Could there be anything wrong with my setup?

I too have this problem. The projects is broken because of this. By the way how do you invoke Projects.rebuild! from Ruby CLI?

I just start the CLI for the production environment and type "Projects.rebuild!" (autocomplete finds it). Then the missing entries are added to the DB.

Thanks! Its working now. I confirm that there is some problem with 105.

Hey, i seem to have the same issue with the lft/rgt not being populated, but when i tried the Project.rebuild! command in the CLI i instead got this message:
ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: parent.rgt: SELECT count(*) AS count_all FROM "projects" LEFT OUTER JOIN "projects" AS parent ON "projects"."parent_id" = parent.id WHERE ("projects"."lft" IS NULL OR "projects"."rgt" IS NULL OR "projects"."lft" >= "projects"."rgt" OR ("projects"."parent_id" IS NOT NULL AND ("projects"."lft" <= parent."lft" OR "projects"."rgt" >= parent."rgt")))
Not sure what to do to fix this though.

I have the exact same error.
Have you had any luck fixing it?

No, sorry. But invoking Projects.rebuild! from the CLI seems to be a decent workaround (at least for me), up to now I didn't face any problems.

I can´t find Projects.rebuild!.
The CLI in this case means the bash console, the irb interpreter, something else?
And how exactly do you do the invocation?
On another note, I installed rails-2.2.2 from source and added symlinks in .../vendor/rails to /usr/lib/ruby/gems/1.8/gems/...
Is this the right procedure?
Thanks!

Oh, and by the way, that installation didn´t have an ActiveModel folder to link to, maybe that was the problem.
Can anyone shed some light on this?
Thanks!

I have the same problem as Alejandro. I have no Idea how to launch this command "Projects:rebuild!". I tried to do this using the redmine console (ruby script/console production) but I got the following error after I had typed "Projects:rebuild!" from this running console.
Loading production environment (Rails 2.3.5) >> Projects:rebuild! NoMethodError: undefined method `Projects' for #<Object:0xb756194c> from (irb):1
What are you guys talking about speeking of "CLI"? I have a problem with the project overview in redmine. The nesting hierarchy of projects and subprojects just sucks although the parent-relations in the table "projects" are correct.
I suspect it can have something to do with those fields 'lft' and 'rgt'. What are those fields responsible for? Looks like some kind of pointers to me.
Did anybody else face this nesting problem to?
Thanks!

Projects.rebuild! of course but still problems
Loading production environment (Rails 2.3.5) >> Projects.rebuild! NameError: uninitialized constant Projects from /usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:443:in `load_missing_constant' from /usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:80:in `const_missing' from /usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:92:in `const_missing' from (irb):1
The question remains the same. Can those fields 'lft' and 'rgt' be responsible for the wrong nesting displaing the project overview?
