Granted, I''m still very much a newbie, but after reading an article on AJAX that basically states at one point that just because you can use AJAX doesn''t always mean you should, I have to ask: Why bother contacting the server (even if it is an insignificant amount of bandwidth) to validate the sanity of form data (unless you''re actually validating against something in

I''ve been reading the tutorial and I have problems with the TinyInt(1) for the attribute "item.done". I thought this thread would be the best to post it. I''m using Rails 1.1.14. When in the partial template _list_stripes appears: <%= list_stripes["done"] == 1 ? show_image("done_ico.gif") : "&nbsp;" %> it always returns the

Hey all -- I''ve been using enumerable char(1)''s with ''y'' and ''n'' values for my Boolean columns in Rails, but it strikes me there should be a better way. How do you setup columns that represent true/false-ness in your schemas on Rails? Wondering what kind of standard approaches there are other than me writing something like class MyEntity

Hi, I am a RoR newbie and I''ve been experimenting with different databases (mySQL, PostgreSQL, etc.) and different table types (MyISAM vs. InnoDB). Is there a preferred database/table type for RoR development. I like how MySQL''s InnoDB tables enforce referential integrity, but these tables require a lot more storage space then MyISAM tables. For everyone with a lot of RoR

Hello, there is a table that has a column TINYINT(1) called status. Through mysql console I see its value as 1 (when is true) but if I do this in Rails console: Mytable.status => true give me "true" rather "1". How could I change 1 to true using some method? Or true to 1? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are

Hi, Correct me if I am wrong but there doesn''t seem to be an easy way to add validation outside the pre-built ones (validates_presence_of, validates_lenght_of, etc.). Ideally there should be something like: Class Person < ActiveRecord::Base validates :my_method, :on => create, :message => ''was not valid'' def my_method(param) false unless

I''d like to be able to run both development and production as follows: www.mysite.com will be running production dev.mysite.com will be running development It should run the same code base. The server is RedHat Enterprise 3, Apache, FastCgi. My problem is I don''t know where to set the environment so the application bootstraps depending on the virtual host (www/dev).

I have 2.2 installation on Centos 7, and, I'm trying to setup a new server, and, 'clone' existing setup: Dovecot/Postfix/Mysql on new Centos 7 installed from RPM 2.3.4.1 (3c0b8769e) I then copied/overwrote from old to new /etc/dovecot/*.conf (but not conf.d files), created self certs in place of old server certs and, started Dovecot is that totally dumb, and, how should I do this,

this may seem silly but i just noticed that if in mysql the column which is a tinyint(1) happens 2 or greater, by a chance of glitch or corruption in the database(i did it manually ofcourse but i am speaking hypothetically), rails would see it as false. but i find that really wrong seeing how in mysql it sees any non-zeroes as true. i really think if it does happen to be any number other than 1

Hi, I''m trying to get through the popular "Four Days with Rails" tutorial and am experiencing some problem with the "Priority" of the item. Right from the start, RoR seems to want to consider it as a value that must be boolean. The scaffolded code asks for "True/ False" as the input. PHPMyAdmin shows that the database thinks it should be an unsigned
