Hello, I have 2 models (category with id(auto_increment), name and item with id(auto_increment), category_id, name). But I want to store the data with only one form that creates a new category and the corresponding items at the same time.

Greetings railsers - I''m trying to add to a collection through HABTM, but the sql insert is trying to insert a PK rather than letting mysql produce the auto_increment''ed PK. ## @medication_dose holds a validated, saved model @medication_dose.medication_frequencies << MedicationFrequency.find (:all) The above bails with, Mysql::Error: #23000Duplicate

Hi, I have good this cool challenge from my boss on developing a very simple cms-like system to publish articles within. The caveat is that he wants to have multi-lingual content. At first I thought RoR would be perfect for the assignment but right now I''m not so sure. My first attempt involved creating a table for each model/languagde like this: articles_en articles_dk articles_de

Hi all, Im slowly moving forward, but there''s something a miss. I can save some relational records to tables, but only once. For an unknown reason, the primary key (id) of the child table is not automatically increased. (I can only perform one save, (the first records id field holds the value ''0'') and during the next save it says: Mysql::Error: Duplicate entry

Alrighty folks, I''m really trying here, and want to succeed with Ruby on Rails.

Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:imagePath notation does not work for me, although this

Hi All, I want to test REMUS over XEN, I would like to know the basic steps to be followed . I have installed xen4.1 on debian and i didn''t find any command related to remus, is there any steps which i have to carry out? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Dear List, i''m experimenting with remus with the following setup. dom0: - Debian Squeeze - Jeremy''s 2.6.38.48 kernel - xen 4.1.2 recompiled from sid - DRBD for block device backend domU - Debian Squeeze Remus is working fine unless i try to give more than 1 core to the domU. Here''s the error from remus when i''m trying to enable it for an SMP domU:

Hi, i already tried to ask this and did not obtain any answer. Is remus is supported in Opensuse Linux actually ? Regards _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I noticed recently that there is no real easy way to get the kernel driver for blktap working in mainline. I''ve pulled down the source from Daniel Stodden''s linux git tree on xensource, but it looks like it''s for debian and I''m running Fedora 14, so I''m trying to sort it out. I run the 3.1.x kernel and don''t want to go back to the 2.6.32 that

Hi, I''m doing my master research and I need to adapt remus code. Now... I wanna get the checkpoint size (memory + disk) on each period. Does someone know what function does this? I think some *fd *object''s function in remus code could just get the memory size. Does someone help me? Thanks _______________________________________________ Xen-devel mailing list

I have a schema for ~15 tables in MySQL. I need to migrate it to Oracle though I''ve never used Oracle before. I see that Oracle doesn''t have an auto_increment built in. One must create a trigger table for each auto_incrementing id. I''m contemplating translating my MySQL schema into a Ruby migration script. Do you know if Ruby migrations will generate enough SQL to

Hello, we are using debian, xen 3.x and a iscsi-storage with ext4 as filesystem. Heartbeat is used for xen-ha. Now we like to change to xen 4 and remus. The iscsi SAN is available on active-Dom0 and backup-Dom0. I don´t have to use the disk buffering, as I understand remus right, because the file system on both machines is the same. With ext4 we don´t had problems at the xen3-Cluster on

Hello everyone, I''ve managed to configure and start Remus. However, it works only while the protected server is not loaded. As soon as I start a memory-intensive server application, the stream of Remus messages stops, leaving me with an error message. I think the message is not always the same, but here is what I''ve got from the last run: PROF: suspending at

Hi all, in mysql, you can set the following environment variables: set @@auto_increment_offset = 4; set @@auto_increment_increment =10; such that: create table people (id int auto_increment primary key, name char(100)); insert into people set name=''Giuseppe''; insert into people set name=''Laura''; select * from people; +----+----------+ | id | name |
