Crear datos aleatorios con restriciones
Hola,
0. La falta de 'elegancia' hace que sea mas dificil hacer cambios al
codigo. Por ejemplo cambiar n.classrooms <- 4 a n.classrooms <- 20
1. Cuando tengo solo 4 puedo hacer esto:
schoolGrade$A <- Teachers$Teacher.ID[1:cuttoff1]
schoolGrade$B <- Teachers$Teacher.ID[1:cuttoff1]

Converting observe_field to UJS in Rails 3
I am trying to rewrite my website in Rails 3 and Ruby 1.9.2.
Can some one help me convert my observe_field which is working under
Rails 2.3.5 to Rails 3. I would like to avoid using JQuery as over the
last year everything I have tried in JQuery has failed, including this
one. Perhaps due to my lack of knowledge. I would not like to install
the legacy upgrade.
What I have in my website is several

Crear datos aleatorios con restriciones
Perdon por no se lo suficientemente claro :(
Tu codigo produce `validPairs` que tiene 7 variables y 360 observaciones.
Donde
> validPairs[1,] V1 V2 V3 V4 V5 V6 valid
60 e1 g1 c1 e1 g1 c2 Valid
indica que un maestro tiene asignado c1 y c2 en la escuela e1 y el grado
g1. Correcto? Si es asi, esto es casi lo que queira producir y creo que
puedo llegar a donde quiero usando tu codigo de base.

Nuby: HABTM and drag-and-drop views
I have two tables that have a HABTM relationship: Teacher

Strange permissions problems
I had this problem some last year and never got it figured out. Now it
is bugging me. It seems that sometimes when a student writes his/her
file to a directory, it will not keep the correct group. It puts
his/her main group as the group owner and that fouls things up. Here is
what I have.

More than one has_many :through association between the same 2 models
I wonder if you can have more than one has_many :through association between
2 models.
For example...
I have a model Teacher and a model Class
Now, 1 Teacher works in many Classes, right?. So I need a join model like
class Work < ActiveRecord::Base
belongs_to :teacher
belongs_to :class
end
But I also would like to know if a teacher CAN teach a class before I

has_and_belongs_to_many on legacy DB
I am working with mapping ActiveRecord onto a legacy database. All is going
well (using set_table_name, set_primary_key, etc), but I can''t get my

My contrived example of the situation:
Student has_and_belongs_to_many Teachers. This is mapped via table

Vista and Samba
I was just setting a Windows Vista machine up on my network and have the
following problems.
If the user logs into the domain, then there are no network drives
showing. It is as if the script is not executing.
If I logon locally with an administrator and then run '\\server-name' to
get a list of drives, I can see them but nothing shows up in any of them

I want to ensure that a teacher is not assigned the same course more
than once. In other words, if I''m in the courses_teachers table as
teaching Spanish 101, if someone tries to add that same teacher/course
combination to the table again, it will not be allowed.
