Hi .. A conceptual question this time. I have the relation: member (m)---(1) member_type The schema looks something like this (simplified + PGSQL) create table member_types ( id serial, info varchar( 20 ) not null, primary key( id ) ); create table members ( id serial, first_name varchar( 100 ) not null,

I''m trying to wrap my caffeine soaked brain around has_many :through following along at: http://rails.techno-weenie.net/tip/2005/12/23/teaching_your_blog_model_new_tricks_with_has_many_through I think my models are a little more complex than what fits this narrative. I have a directory of members, each member can belong to multiple categories. The category table references itself

Hi .. I am new to Rails and it is not clear to me why I am getting the following error. Any help appreciated. -m. $cat app/views/admin/new.rhtml <% @page_title = "New member..." -%> <%= start_form_tag( :action => ''create'' ) %> <table> <tr> <td> First Name: </td> <td> <%= text_field(

I created the well known group Domain Admins pointing to a local group, but I am not able to add users to the group -- it claims I can only add users to local or global groups... But I only see local, domain ,well-known, builtin. There are no global groups unless one would include all groups that are not local (i.e. domain, well-known, and builtin).... So why doesn't it want to let me add

Hi .. I am getting started with RoR and having fun :-) So, my problem is how to integrate the static and dynamic sides of the site I am making. I have a standard look-and-feel, the usual stuff, graphic header, left sidebar with menu, content in the centre. Some pages are static -- main page, contact, that kind of thing -- and some are dynamic, such as the admin pages. My problem is I

Hi all, A couple quick select helper questions. First, how do I set the initial selection value? Second, how do I create an "empty" element in the list? Or should I just unshift nil onto the list? I looked over the docs, but didn''t find anything specifically about this. If this is covered, just point me to the appropriate link and I''ll be on my way. :) Thanks,

Hi all, I have 2 tables and a standard one-to-many association. How do I substitute the following sql with ActiveRecord calls so that it uses just one sql statement: update geo_entities set terminal_id = 3 where id = 10 or id = 23 or id = 87; Thank you!

I''m looking for a way to select a default value from a select box, like this: select("user", "role_id", Role.find_all.collect {|r| [ r.name, r.id ] }, { :default_value => ''5'' } (of course, there is no ":default_value") If the form is being used on a ''create'' page, it should display a default in the select box. If

Hello all, The itanium demangler in libcxxabi (and also, llvm/lib/Demangle) is really slow. This is largely because the textual representation of the symbol that is being demangled is held in a std::string, and manipulations done during parsing are done on that string. The demangler is always concatenating strings and inserting into the middle of strings, which is terrible. The fact that the

I just booted Xen unstable (2.6.16 kernel) and Domain0 is running fine, all on Debian 3.1 Sarge unstable on amd64. I can''t do much else: Error: Error connecting to xend: Connection refused. Is xend running? What''s wrong and how do I fix it? -- Neal Probert (nealzilla@probestar.com) aka Niall Lundkvist

Hi, We want to display on a small LCD screen next to our meeting rooms and optionally let people book the room from the panel. We looked at different providers and those solutions either works with Exchange or Lotus Notes... Since I already have code to fetch events from any CalDAV/WebDSV servers, I'm looking at building the system myself. So I'm wondering if any of you can recommend

I'm trying to fix a CentOS (5.5 x86_64) VM that we have where it become unstable due to swapping. But I did notice something: I have 10 httpd processes, and 5 of them are using 13 MB of resident memory, the other are using between 91 and 96 MB of RAM. I find it quite strange to see such differences in RAM usage. I ran a "lsof -P -p" on the processes, and I didn't see any major

Hello, We are planning to moving most of our servers to ESX but before buying our SAN, we want to do some I/O stats to see if iSCSI is enough or if we have to go with FC. So I found a plugin for Nagios that can log I/O stats with iostat. So far it's fine with single disk/one partition servers, but on our Oracle Database 10g server, we have two drives in RAID 1 (/dev/sda) and 4 other

We have to rebuild our kernel to add support for a Mainpine fax board on a CentOS 5.5 board: http://www.hylafax.org/content/Handbook:Basic_Server_Configuration:Modem-specific_Guidance#Mainpine_IQ_Express We followed all steps, but when calling rpmbuild, we are getting: [root at hylafax SPECS]# rpmbuild -ba --target x86_64 kernel-2.6.spec Construction pour plate-formes cibles: x86_64

Yesterday I got the beta version of ROR recipes book and the recipes are great. For those of you still thinking about it, I highly recommend the book. The only thing I wish is that if there were some more recipes (greedy me), especially AJAX related and installing an application within your current application. For instance, it will be great to see how one can implement the typo blog

Greetings all, I''m forwarding a copy of an email I sent reporting attempted break-ins on my main server, earth.terran.org. I am forwarding this because I think it is relevant that folks watch for this kind of activity in their logs to catch people who "try doorknobs" in the middle of the night. After sending this email, I sent a talk request to the user, who was still logged

When I explain RoR to someone I don''t have a convincing argument that explains why everything is so automatic and transparent, but relationships have to be encoded by hand in models. That shows I don''t understand well that part of AR. There''s the argument that says that not all databases offer metadata about foreign keys, but the natural question then is that,

Someone I was speaking with this evening claimed they have installed the latest named rpms yet they are still getting exploited daily and being hacked. Do the latest rpm''s for the named 4.9.x stuff fix all the root exploits or is this person just an idiot who probably has holes elsewhere in the system?

I''m in the process of locking down as much of my systems here as possible as to available ports. I am down to only a handful but am not sure how much of a security risk they pose and was wondering if anyone here might be able to comment, or suggest secure versions to run: 21/FTP (WU-ftpd v2.4.2 BETA 14) 22/SSH (1.22) 23/TELNET (Netkit 0.09) 25/SMTP (Sendmail

I am working on starting Virtural Servers at my office and have questions regarding disk partitioning recommendations. I am using SLES 10 SP2..... RAID 5.... 280G available... no external storage... 1 - Should the DOM be on primary partition and then place the VM''s in LVM? 2 - Should I create partitions in the LVM for each of my VM''s separately or can they all reside on the
