I want to change parts of this form in order to use default values (with a disabled input). The problem is if I change it from text_field to text_field_tag that part of the form stops functioning.

I side with David when it comes to databases. They suck! Just my own opinion. So what about the people who don''t want to define validations and stuff in the database, but still want to be DRY. I really hate how the schema is separate from my models. I kind of like how Django defines the table attributes in the model. I was think about trying something like that in Rails. You could

Hi, I've been foolish enough to let Partition-Magic move/resize/etc. my partitions without a prior backup. My ext3 /dev/hda7 (was RH 9) is no longer recognised by fsck. I tried fsck -b 8139, 32768 and 65536 - but am not quite sure about if these are the right ones to try. So far I created another partition with same number of blocks and did a backup with dd if=/dev/hda7 of=/dev/hda8

Hi all. I am currently thinking about how to do the following: I have the following models. Team Person Team has various positions (manager, programmer etc.) I would like each one of those positions to reference one or more Person records.

Hi there I have an habtm association between 2 Models. I regularly have to truncate the table on one side of the relationship and repopulate the table with a fresh csv file. I notice that f I do Model.delete_all, none of the records in my habtm join table get deleted, whereas if I use destroy_all they do. However, the overhead of using destroy_all is too great. For the amount of records I have
