NoMethodError in Todo#list

I've installed Tracks 1.04 sucessfully (at least I thought so). After playing around a little bit, setting up a few contexts, projects and actions, I am now getting a NoMethodError in Todo#list on the start page (http://localhost:3000/). I can access other pages, like e.g. http://localhost:3000/projects, but get the same error on accessing http://localhost:3000/todo/list.
The full message is the following:

NoMethodError in Todo#list

undefined method `hide?' for nil:NilClass
RAILS_ROOT: .

Application Trace | Framework Trace | Full Trace
#{RAILS_ROOT}/app/controllers/todo_controller.rb:36:in `list'
#{RAILS_ROOT}/app/controllers/todo_controller.rb:36:in `list'
Request

Parameters: None

Headers: {"cookie"=>[], "Cache-Control"=>"no-cache"}


As I really like the application so far, I would appreciate any help.
My config: ruby 1.8.4 on Mac OS X 10.4

Hmm, that's odd. What database are you using? From the error I'd suggest that you might have an action which has somehow not got a context_id set, or else the hide column of the context is somehow set wrongly. Can you check your database and see whether all your actions have a context_id set, and that the hide property of contexts is set properly (should be either 0 or 1 for MySql databases or 't' or 'f' for SQLite).

I'll set this as help because I don't think that it's a bug with Tracks itself.

Hi, thanks for your help.
After examining the database (sqlite3), I found an entry in the todos table with an invalid context_id (and a project_id of NULL).

I recall that I deleted the first context after playing a little bit. Apparently a todo remained with a context_id which no longer exists. This causes the above mentioned error message. After deleting that todo-record from the table everything works again fine.


So it seems to be an error/defect that when a context is deleted, the todos which belonged to this context now have invalid context ids, thus leading to the 'NoMethodError in ToDo#List'.

Update: I just reproduced this behaviour. Reset severity to critical.

You're absolutely right -- sorry that I closed it prematurely. The reason that I thought it couldn't be down to 'orphaned' next actions is because we had a :dependent => true option in the context model, which deletes next actions belonging to deleted contexts. However, when nic merged his multi-user stuff into the trunk, this somehow got lost and I didn't notice.

It's reinstated now, and deleting a context also deletes any next actions within that context. Fixed in [206].

Applied your fix http://dev.rousette.org.uk/changeset/206 and now it works as it should.

Thanks again for your quick support.
