I have a case where the user must select items from a basket and use them with different forms.
Example:
I will show you how to use the checked boxes from the first form with the submit action in the second form
It would be easy if the form could be one – less support.
I am starting with those two forms
- Helper form – Form with checkboxes
- Action form – the form that will do the real action based on the selected items in the helper form
Here is how it looks the helper form. All the checkboxes are tagged with the class=”selectable”. Here is rails example but you can implement it pure html.
<%= check_box_tag('selected[]', true, image.selected?, :class=>"selectable") %>
Then we can select all the checkboxes with this javascript.
var make_to_hidden = $$('input.selectable');
Put on your action form an id so we can access it easy in this case:
Lets add those checkboxes from the first form to the real action form with this javascript function
function import_selected_basket() {
var make_to_hidden = $$('input.selectable');
make_to_hidden.each(function(item) {
if (item.checked) {
var new_item = new Element('input', { 'type': 'hidden', name: item.name, value: item.value })
$('mail_form').appendChild(new_item)
}
});
Its aways nice to know whats going on in rails field

От известно време си имаме на http://www.cenite.com чисто нова търсачка.
Преди беше просто досадно да се търси в сайта и макар, сайта върши работа.
Резултатите с новата търсачка са налице, вижте разликата:
- Преди за един резултат се чакаше приблизително от 2 до 4 (олеле) секунди.
- Търсеше се само в името на продукта
Сега:
- Търсенето става мигновенно – повече време отнема да се изобрази страницата от броузера :)
- Търсенето е едновременно в заглавието на продукта, както и в описанието му, като се дава превес в резултатите съдържащи ключовите думи в името на продукта.
- Може да се избира по кой полета да се търси, макар че не ми е останало време да публикувам HELP към търсачката.
- Сортиране по точност на намерите резултати.
- Отпаднаха притесненията за Иванчо ;drop table students;
Изглежда и посетителите също оценяват предимствата на новото търсене, от 1000 посетителя на ден в момента са над 2500 като всеки ден се увеличават.
I got this error when I have to upgrade one old project from rails 1.2.5 to rails 2.1 (the problem is not in rails)
ActionController::MethodNotAllowed Only get, head, post, put, and delete requests are allowed.
The exception:
ActionController::MethodNotAllowed (Only get, head, post, put, and delete requests are allowed.):
/usr/lib/ruby/gems/1.8/gems/actionpack-2.1.0/lib/action_controller/routing/recognition_optimisation.rb:65:in `recognize_path'
/usr/lib/ruby/gems/1.8/gems/actionpack-2.1.0/lib/action_controller/routing/route_set.rb:384:in `recognize'
I got this error only when I access URL’s with param like
http://127.0.0.1:3000/dod/images/show_big_image/1639
I found that the problem was in the :id because without the :id the method was called correctly
This means that there is something with the routes.
Not working routes.rb: ….
map.connect '', :controller => 'auth' # Install the default route as the lowest priority. map.connect ':controller/:action/:id' map.connect ':controller/:action/:sort_key/:sort_order'
it will work if you swap the last two lines….
map.connect '', :controller => 'auth' # Install the default route as the lowest priority. map.connect ':controller/:action/:sort_key/:sort_order' map.connect ':controller/:action/:id'
It seems that it does reading the comments in the routes.rb is usefull. There is written:
# Install the default route as the lowest priority. This error also occurs if you haven't restart your webserver. I know that there is no need to restart it but its true, try restarting and check.
Here is nice tutorial how to move your project from rails 1.2.x to 2.0
- upgrade the gems: http://wiki.rubyonrails.org/rails/pages/HowtoUpgrade
-
gem update --system

- nice task to find the deprecated elements: “rake -T deprecated”, 10x!
Java install
ls /usr/portage/dev-java/sun-jdk/
emerge -av =dev-java/sun-jdk-1.5.0.13
java-config -L
java-config -S 1
/usr/sbin/env-update && source /etc/profile
Emerge and Equery
Taken from here
emerge brings in new packages. equery looks at the package database.
- update repository:
- emerge –sync
- install package with query
- emrge -av sun-jdk
- start with this software
- emerge links wget htop
- emerge …
- manipulate package database
- emerge -NDtu world
- –update packages and packages that depend on updated packages (–deep) in the world list. Give output in –tree format. Consider packages changed if their USE flags have changed (–newuse, -N) Add –pretend (-p) to just see what it will do first.
- emerge –skipfirst …
- skip first pkg on a rebuild; very useful if something doesn’t work
- equery …
- query package database
- equary belongs
- who owns these files?
- equery list
- list packages on system
Maintenance
Taken from here
Do this whenever you want a steaming pile of fresh packages.
# emerge --sync
# emerge --update system
# etc-update if necessary
# emerge --update world
I have seen Meddle to do it this way
emerge –newuse –deep –update world
emerge –ask –verbose coreutils
emerge –resume
Fix the mktemp / coreutils block in Gentoo
Looks like mktemp is now provided by coreutils. No wonder. This block has been bugging me (read: I’ve been ignoring it) for months.
To fix just unmerge mktemp and update coreutils.
Update: Same for the setarch / util-linux block should you come across it. Unmerge setarch.
.clearfix
<div style=”clear: both”> – do you remember this? I hate it.
The people has found a solution for this.
http://www.positioniseverything.net/easyclearing.html
.clearfix:after {
content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
.clearfix {display: inline-block;}
/* Hides from IE-mac \*/
* html .clearfix {height: 1%;}
.clearfix {display: block;}
/* End hide from IE-mac */

PNG Patch for IE
Since IE6 doesn’t render PNG-24 properly, the following hack is required in order to display the transparent PNG (add anywhere in between the <head> tag):
<!--[if lt IE 7]>
<style>
h1 span {
background: none;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='gradient.png', sizingMethod='scale');
}
</style>
<![endif]-->

All my spiders were taking all content from a website on a single visit starting from the begining.
It seems that the idea of remembering which urls “produce” links with content is not so very bad.
Here is what I found for diri.bg – a local Bulgarian SE.
I see that diri.bg hasn’t remove from their page
show_categories.php
Even I have no links to this page. Check the result here
Ops. Google do it the same way: here
Then how to get rid of old pages without leaving “bad” links in internet?
I will try to put show_categories.php in robots.txt to see what will happen with this page.
