Im having an issue that seems to only happen when trying to use a transaction. Ive used transactions many times in the past and Im at a loss as to why im getting the stack level too deep problem. SystemStackError - stack level too deep: actionpack (3.2.13) lib/action_dispatch/middleware/reloader.rb:70:in `'' I have a StackOveflow with more detail -

I am trying to clean up unnecessary lines (even as I hack my way forward adding more garbage) I have two questions on lines I have trying to keep the database and session info reflecting changes: def associate_pupil_to_teacher @teacher = session[:teacher] @pupil = Pupil.find(params[:id]) @teacher.pupils << @pupil @teacher.save #Q1 session[:teacher] = @teacher #Q2 end #Q1 do i

I still want to get this into Rails for all connection adaptors, but for now I''ve hacked my own addition on for just PostgreSQL. The following code extends every Column object returned by MyModel.columns to support a new #required? method, which indicates if the column may or may not be null. The following is a huge hack - suggestions on a cleaner way to add this functionality

Previously, I posed the question pasted down below to the list and received some very helpful responses. While the code suggestions provided in response indeed work, they seem to only work with *very* small data sets and so I wanted to follow up and see if anyone had ideas for better efficiency. I was quite embarrased on this as our SAS programmers cranked out programs that did this in the blink

Hi all I''m in the process of trying to make my first project on Rails after doing the tutorial in AWDR. I picked a project which I thought would be easy as I already have the PHP/MySQL implementation. Unfortunately I''ve now hit a snag and was wondering if you could help? I have a table called "races" and a table called "courses". The relationship is:

Greetings, I recently upgraded Samba on an Ubuntu 14.04.2 server from version 4.1.9 to 4.2.3. Upon rebooting Samba process goes into a running state then after a short time it will go into an uninterruptible state. If I check the log.samba, it appears that it is attempting to start, then hangs at the following: [2016/06/23 15:16:00.329503, 3] ../source4/param/share.c:124(share_register)

I''m currently doing all of this just to have a drop-down list of Courses for a particular student: ===== edit template ===== <%= f.select :course, @courses, :selected => @student.course.id %> =================== ===== students controller ===== def edit @student = Student.find(params[:id]) @page_title = "Edit #{@student.full_name}" @courses =

Greetings, I am having a problem with one of my DCs (DC3) replicating DomainDnsZones. On DC3 replication is successful on both Inbound and Outbound with both of my other DCs. On both of my other DCs (DC1 & DC2) I only get a failure with Inbound replication for DomainDnsZones from DC3 with a result 8442 (WERR_DS_DRA_INTERNAL_ERROR). If I try to force replication to DC3 from DC1 using

Hi. I get some strange results when using rename_column on a primary key in a migration. It seems like the migration script removes the auto-increment property if you rename a column. This is a minimal example. create_table :foo, :primary_key => :foo_id do |t| t.column "name", :string end # renaming the primary key makes auto-increment disappear. rename_column

Hi all. Got a stupid-simple question about associations. I have two models - school and course. There are a fixed number of schools (set up in the migration). Each course is assigned a school and a school will be associated with multiple courses... How do I set up the associations? Do (can) I have School :has_one :course and Course :has_many :schools? Does the schools table then get a course_id

Greetings, I'm currently experiencing an issue with two of my three Samba servers where one Samba process is pegging the CPU usage and eating up a lot of virtual and resident memory. While this is happening I get a "ERROR(runtime): DsReplicaGetInfo of type 0 failed - (-1073610723, 'NT_STATUS_RPC_PROTOCOL_ERROR')" error when I try to run the samba-tool drs showrepl command.

Here's my edited smb.conf and the output of the testparm. As you can see I'm not setting that in my smb.conf and it appears to be turned on by default in Samba 4.4.4. I was going to update Samba on DC1 to 4.4.4 as well, but haven't done that yet. It's currently on 4.2.3. Should I upgrade that as well before changing anything else? Thanks!

Hi, I''m calling a helper I''ve written - format_time() that is called from my views with a given time that was selected from my database and was returned to the view via an instance variable. When I call format_time from a partial, I see that I get some kind of String error and the partial won''t render. Basically, the object being passed in to format_time is already a

Greetings, A little while ago I started receiving an error any time I tried to run a samba-tool command on my pdc. My bdc is showing inbound and outbound working just fine with the pdc. The error I am receiving is ldb: unable to stat module /usr/lib/x86_64-linux-gnu/samba/ldb : No such file or directory. Is this just as simple as creating a soft link to /usr/local/samba/lib/ldb? Any advice

Hola, Esta pregunta la hice en stackoverflow <http://stackoverflow.com/questions/31137940/randomly-assign-teachers-to-classrooms-imposing-restrictions/31143808#31143808>pero nadie pudo contestarla. 1.

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] schoolGrade$C <- Teachers$Teacher.ID[(cuttoff1+1):n.teachers] schoolGrade$D <-

Gracias Carlos, Tu codigo es un gran paso en el sentido correcto pero no produce exactamente lo que estoy buscando. Mi "solucion" en stackoverflow <http://stackoverflow.com/questions/31137940/randomly-assign-teachers-to-classrooms-imposing-restrictions/31143808#31143808> produce un data frame `schoolGrade` con 240 observaciones y 7 variables.
