[Rails] Serving a PDF document

[Simon Macneall]

Hi all,

Been banging my head against this for a little while so figured I see if  
anyone here could light the way.

Our site receives input from fillable pdfs as XML (XFDF to be precise) and  
processes the information. We also need to be able to re-export the filled  
PDF. To do this you send the xfdf file with an href to the original pdf  
document.

If I point the href to a static PDF (so, put it in the public folder)  
adobe opens and fills the pdf correctly. However, if I point to the pdf  
using a dynamic URL to rails then Adobe just doesn't fill the pdf.

So my question, what is the difference between
http://localhost:3000/pdfs/TACServiceReport0908.pdf - where pdfs is a  
folder in the public folder of the app
and
http://localhost:3000/forms/show/4.pdf - this renders the exact same file  
using one of the following (I have tried them all)

send_file(@form.pdf_filename, :type => 'application/pdf', :dispoisition =>  
'attachment')
send_file(@form.pdf_filename, :type => 'application/pdf', :dispoisition =>  
'inline')
send_data(content, :filename => filename, :type => "application/pdf",  
:disposition => "inline")
send_data(content, :filename => filename, :type => "application/pdf",  
:disposition => "attachment")

and how can I make the second method behave like the first.


Thanks
Simon

Yes, that's what it looks like from my end.  I ultimately decided to
leave in the date + time concatenation in my named scopes to handle
databases with & without time columns.

[Rails] No Method Error when using a plugin

[dangerp]

I'm at kind of a weird roadblock right now.  I'm fairly new at rails,
but what I am trying to do right now seems too simple to not work.  I
installed the "spawn" plugin using the following:

 ruby script/plugin install http://spawn.rubyforge.org/svn/spawn

I verified that the plugin was properly installed into vendor/plugins/
spawn.  I tried using the code snippets that the author provided:

spawn do
logger.info("I feel sleepy...")
sleep 11
logger.info("Time to wake up!")
  end

and I get the error: undefined method "spawn".  From what I
understand, since it is in the plugins directory, I do not need to
require or otherwise initialize this plugin (although I did try
requiring it).  I am getting the same error in my application and when
using 'ruby script/console'

I don't see what I am doing wrong.  Does anyone have any ideas?

Okay, I've been taking a look at this, and I'm facing a problem. When 
I've scanned a string I want to actually replace all the {some_partial 
foo:bar}'s with partial renderings.

I've been looking through the StringScanner documentation 
(http://www.ruby-doc.org/core/classes/StringScanner.html), but it 
doesn't seem to cover the topic of replacing matches instead of just 
extracting it, if you know what I mean.

How can I replace a {some_partial foo:bar} match with a partial 
rendering?

[Rails] Re: passenger dedicated server

[fRAnKEnSTEin]

Hi,

>Maybe you should define /exactly/ what you mean by "dedicated server"

Well i mean that i have full root access to all accounts on the
server. And that i can install, delete, update etc in any way i want
to. Only my apps are installed and running , i have all the power over
the server, this is what i mean with "dedicated server"

>I was installing on my OS X system -- just another *nix box. A server is a
server is a server. Because you installed server software on it :-)

I already installed passenger on my MAC, and it works, but that is
obius, because my MAC:

1- Is a local eviroment, that means that all the installations are
donde like root, and more important with a very low security
configuration(my mac is a testing eviroment not a production one)

2- As a local machine, is a testing eviroment, so it does not have any
high securiity, firewalls, special users and all that stuff that a
real production server has and that usually make things harder to
install and configure, for a simple example i connect in my local
machine to mysql using user root with no password, but in a real
producction eviroment this can not be done, so i have not to deal with
this stuff when installing something in my *nix local machine :),
thats why passenger was easy to install :-)

>Maybe you should do a test install on another system where you aren't 

>wrestling with "cpanel" to validate the basic process.

the cpanel stuff was just an example, i am not sure if it is the
cpanel who causes the problem, i was just giving an example that in a
production eviroment exists a lot of "extra" thing that are
configurated different and that may cause tha passenger install not so
easy to do, maybe cpanel, maybe some chmod problems, maybe some lost
symbolic links problems etc

>What company did you get your dedicated server from

www.jaguarpc.com

>Most dedicated
servers has the ability to be installed without a control panel and
most of the time it is easier to do custom installs like pasanger/
mongrel or other without a control panel like cpanel

of course, as i said before i have installed passenger already, the
problem i got is that i can not configure it properly using just the
instructions that passenger installing process gives

>did you install wget on the server (yum install wget) and/or links 
(yum 
>install links) this will let you "test" from the local server to

i have installed many software using yum, and wget was already
installed when i buyed the dedicaded server, and both work just fine

>AND THE BIG QUESTION! IS THE CPANEL FIREWALL OPEN

I am not sure, but is this important for passenger to work properly?

Thanks for your support,

that's basically going above rails, using mysql where clause
but with rails:

  def tagging=(tagging)
self.tags.each do |tag|
  tag.destroy unless tagging.include? (tag[:technology_id].to_s)
end
tagging.each do |tag|
  tags.build(:technology_id => tag) unless tags.any?{|t|
t.technology_id.to_i == tag.to_i}
end

[Rails] Re: passenger dedicated server

[Freddy Andersen]

What company did you get your dedicated server from? Most dedicated
servers has the ability to be installed without a control panel and
most of the time it is easier to do custom installs like pasanger/
mongrel or other without a control panel like cpanel. cpanel is a
great tool if all you want is a few static pages (that is MY take
btw.)

When you got your domain you set that up in DNS to point to your
dedicated servers ip.

www.your-domain.com -> A record -> 1.1.1.1 (dedicated server ip)

Then you have to configure Apache to listen for www.your-domain.com if
you have virtualhosts setup. (If you only have one that will be the
default host and should work anywho... )

You should be able to see entries in the apache logs if you hit the ip
address.

Btw did you install wget on the server (yum install wget) and/or links
(yum install links) this will let you "test" from the local server to
see if everything is working fine there before testing outside...

AND THE BIG QUESTION! IS THE CPANEL FIREWALL OPEN

Maybe you should do a test install on another system where you aren't

[Rails] redirecting to uploaded files directory

All,

I'm running into a bit of a newb issue here. I've created an app with
attachment_fu which by default created a directory within public as
"public/#{tablename}". But now when I try and browse to my default
action for that resource which is the same actionname as my tablename
I get redirected to a file listing of that public/tablename
directory... within my index view of that action I want to display the
file I've uploaded but I cannot figure out why it's redirectiing to
the files directory attachment_fu has uploaded the file to. not sure
if this is a webserver (apache/passenger) or a rails routing issue...

hope that makes sense

[Rails] How to use Rails' exception handling mechanism in a background thread?

[Myron Marston]

I have some simple asynchronous processing that my app needs to do,
and I wanted something a bit lighter weight than any of the gems or
plugins I've run across that handle background processing.  I decided
to roll my own, with the added benefit that I get to use native
threads rather than green threads since I'm using JRuby.

I'm unsure how to handle exceptions in the background thread. I'd like
to pass it to Rails' exception handling mechanism so that it is dealt
with in the same way as exceptions that occur during the normal
request-response cycle (except for rendering the 500 page, of
course).  Since I've got the exception notifier plugin installed, this
would email me, as well as log the exception to the log file.

Is there a way to let Rails handle the exception, where whatever
exception handling I have in my rails app would get used for
exceptions in the background thread?

In case it helps, I've included the code for my background thread
below.

Thanks,
Myron


class UserSubmissionProcessor
  SLEEP_TIME = 30 unless defined? SLEEP_TIME
  @@semaphore = Mutex.new
  @@singleton_thread = nil unless defined? @@singleton_thread

  def self.start_processor_if_necessary
@@semaphore.synchronize do
  if @@singleton_thread.nil?
@@singleton_thread = Thread.new
{UserSubmissionProcessor.process}
  end
end
  end

  private

  def self.process
while true
  begin
user_submission = UserSubmission.find(:first, :conditions =>
{:processing_completed => nil}, :order => 'created_at')

if user_submission
  user_submission.process
else
  sleep SLEEP_TIME
end
  rescue Exception => ex
#TODO: how to I propagate exceptions to rails' exception-
handling mechanism?
  end
end
  end
end

This system that you have installed passenger, was a dedicated server?
if yes, dou you just follow the passenger installation
instructions(i.e copy-paste the lines into http.conf), and just with
that it works properly for you? did not configure any etc/hosts file
or anything else? how do you access the rails app, something like
"http://www.mydomain.com"; where "www.mydomain.com" is the name of the
virtual host you put in in the htp.conf? the name of the virtualhost
must be the same as the domain name that i buyed?

I think the reason is because you need to build the data in memory
because in the moment "def tagging=(tagging)" method setter is run the
blog has not been created and that's why it should go in memory.

The previous code fails when creating new blog this works

def tagging=(tagging)
Tag.delete_all "technology_id not in (" + tagging.to_s + ") and
blog_id = " +self.id.to_s unless self.new_record?
tagging.each do |tag|
  tags.build(:technology_id => tag) unless tags.any?{|t|
t.technology_id.to_i == tag.to_i}
end
  #  Tag.delete_all "technology_id not in (" + tagging.to_s + ") and
blog_id = " +self.id.to_s unless self.new_record?
  #  tagging.each do |tag|
  #self.tags.create(:technology_id => tag) unless tags.any?{|t|
t.technology_id.to_i == tag.to_i}
  #  end
end

It seems php but it works

I'm trying to find out why?? but I don't think I can. Until now what 
I've found is that the Firefox showing errors in its error console is 
from the default javascripts files of which prototype.js I tried to 
trace the problem as it was saying ')' is missing on some number line. 
So, i went there but found everything is fine. ')' is there. Also, the 
line giving error from my code is:

new Form.Element.EventObserver('great_walks', function(element, value)
{new Ajax.Updater('campsites_list', '/user/update_campsites',
{asynchronous:true, evalScripts:true, parameters:'id=' + value +
'&authenticity_token=' +
encodeURIComponent('596f343332f1b5ff9a9bcd36fe9545a71a293677')})})

but according to api docs, observe_field generates similar line only. 
Firefox says 'form is not defined' and highlights this line. I don't 
know what to do.. please suggest... thanks..

If it's a "dedicated server", you should be able to configure it any
way you want -- so why don't you turn off this "cpanel" thing, which
sounds like total crap, and edit your conf files as needed?

I just installed passenger/mod_rails on a system yesterday for the
first time, and it took about 5 minutes. It sounds like your problem
is with cpanel, not passenger.

Just sayin' ... :-)

[Rails] Re: Polymorphic Associations in Rails 2 not configurable

[Aryk Grosz]

Thanks for the input,

I wouldnt say this is exactly a complicated example. Its basically where 
you could infer the polymorphic class from STI type sort of thing. Im 
pretty sure many other people run into it.

The bottom line is that there is no customizablility.

The problem is that the code has sql strings generated with 
"#{variable}_type = X which makes it very hard to replace with a 
function to control the outputted polymorphic sql condition.

I wonder if there is anybody else that has run into the same problems.

Yeah that is was. Simple calling

'read_attribute(:status)' instead of 'status' did the trick. thanks

[Rails] Re: updating attribute in model

[Maurício Linhares]

Hi Allen,

I'm not sure, but this seems to be a before or after save filter, if
it's before_save, instead of update_attribute, just call
write_attribute, when the model is saved it will automatically save
this new value, if it's an after filter, make it a before one.

You're calling status from within status so it's recursing forever.

Replace that last status with read_attribute(:status) after perhaps  
reloading the object to ensure you've got the latest.

[Rails] updating attribute in model

[Allen Walker]

I'm trying to make a change to a field in the model whenever someone
accesses it and it's incorrect. So I have the following in my
ActiveRecord class:

def status
  prev_status = read_attribute(:status)
  if end_date < Date.today
update_attribute(:status, "Expired")
  end
  status
end

I'm getting a "stack level too deep error". Any suggestions on how to
fix and the correct approach to this.

[Rails] Re: Polymorphic Associations in Rails 2 not configurable

Well, that's definitely a "complicated" example :)

I guess you should try to figure out with the core rails guys where
you could hack the code to do just that (what would be infer the name
of the real association from something else), i haven't looked at the
code myself, but it shouldn't be that hard with the right guidance.

Also, if you want to roll your own solution, it isn't that hard and
there's also plenty of work already written about the matter, one of
the best options is Martin Fowler's "Patterns of Enterprise

What you want is a collection, not a member:

[Rails] Re: :find conditions using hour value of saved DateTime object

[Maurício Linhares]

Ideally, you should save this in separate columns, as this query is
definitely going to kill your database (there's no way to make an
index for it, the database will have to go through all rows), but you
could do it like this if you're using MySQL:

find(:all, :conditions => ["HOUR( date ) >= ? AND HOUR( date ) <= ?", 2, 4])

[Rails] :find conditions using hour value of saved DateTime object

[David]

I am wondering if it is possible to use a find condition to find
objects according to the hour, ignoring the date.  For example, i have
a date field storing DateTime objects in the database and I want to
find all objects where the hour is between the times 2:00PM and 4:00PM
regardless of their date.  It seems that to do this, ActiveRecord
would have to perform an operation on each DateTime to find the hour,
such as:

find(:all, :conditions => ["date.hour >= ? AND date.hour <= ?",
2:00PM, 4:00PM])

I know this does not work, but it helps to convey my goal.  Maybe I
have to write a raw SQL condition?  Maybe it is easier to just save
the time values in a separate field for each object in the database in
the firstplace?  I know saves are expensive and was trying to avoid
them.

[Rails] passenger dedicated server

[fRAnKEnSTEin]

Hi,
I am trying to install/configure Passenger on a dedicated centos
server. I have installed passenger successfully, but i am having to
much troubles trying to configure it with my dedicated server, I have
read/saw your screencasts, documentation, buyed peepcode.com
screencasts about this issue etc, but still can not get the thing
working, hope you give me some help.
After passenger installation i pasted all the lines into my
httpd.conf
file as the installation indicates, but well i have some problems
here:
First of all, my dedicated server uses cpanel, this means that i can
not just open directly the http.donf file to make changes because
cPanel rebuilds the file on every update or account creation by
compiling from its userdata files. So any VirtualHost created will be
lost(in fcat any change that i have made will be lost). To create a
custom VirtualHost, in my case i need to create a new domain account
from my WebHostManager and then edit the cPanel files for this
account
located in /var/cpanel/userdata/username folder, not just, copy-paste
the lines that passenger installation gaves to me, at this point i
dont know how to configure this virtualhost thing? besides this,
the screencast of phusion site, tells that i have to configure de
etc/
hosts file but in my case i am not configuring a local passenger
install, so the /ect/hosts could not be configured equal as the
screencast does...or yes?
So where/how i have to paste/configure my passenger installation in
order to work with a dedicated server??? i have tryed a lot of
variations, none of them works, even i have talked with some irc, and
they told me that i have just to follow the passenger installation
instructions(it means copy-pasted the lines in http.conf) but this
this is not working, am i doing something wrong, any idea/advice?
Regards,
Shirkavand

[Rails] Re: gem 1.3.0, netbeans 6.1 "Missing the Rails gem"

[Rick]

Pablo,

I've noticed a similar problem with 6.5M and 6.5Beta.  My problem
turned out to be a NetBeans call to Rake that was failing.  I've filed
with Sun-NetBeansDev, issue 149201.

My problem was in NetBeans source ruby2/rake_tasks_info.rb.  On line 9
of that file is a call to "do_option" method on rake.  This method
appears to exist in rake v0.7.? but not in v0.8.? and rake v0.8.3 is
the one that's currently shipping.

I just commented out line 9 in the NB file and all (appears to) work
fine.

You might want to turn on your IDE logging and check that you're
having the same (rake failure) problem as without the log the info
reported leads you to believe you have a different (bigger) problem.

Rick

Bloody brilliant David!
 The ThinkingSphinx quickstart had the EXACT example i needed. After 
re-reading sphinx install instructions (forgot the --with-pgsq option), 
setup was a breeze and it works perfectly!

[Rails] Finding out how many assets each user has

[AtsoK]

I'm sure this is a dumb question, but how could I find out how many
assets (or anything that belongs to a user) each user has? I can only
think of looping through each user and adding the asset size to an
array, but when you have thousands of users, that can take a lot of
time and memory. Thanks for the help.

[Rails] Why find_by_sql works and find(args) doesn't

[Jay Pangmi]

I'm trying to use Campsite.find(:all, :condition => ['walk_id =
?',params[:walks][:id]]) but fails and instead, if I use
Campsite.find_by_sql("select * from campsites where walk_id =
"+params[:walks][:id]), it works fine. So, I'm wondering why..
I've created combo box as:
<%form_tag do%>
 <%=select :walks, :id, @great_walks%>
<%end%>

thanks.

This might be a php solution but it works:

I guess the places of bugs:

   1.the uploaded file name will be sanitized before move to 
"app/public/object/image/development/id/", so, you can print the file 
name when debuging the file_column, try to find the bugs.
   2.the destination's permission.
   3.get the latest version of file_column.


Good luck.

[Rails] Re: Managing Plugins/Gems for a specific app

[DavidPaquet]

If you are using a recent version of (Rails 2.0+ I think) you can use
the config.gem directive in environnment.rb like this :

config.gem "hpricot", :version => '0.6', :source => "http://
code.whytheluckystiff.net"

After that, you can do a rake gems:install on new installations.

Hi,

I know that it's not your question, but alot of people seem to have

As for your question, I don't know enough about Ferret to help you,
I'm sorry.

[Rails] ActiveRecord adding quotes where it should not using JDBC Oracle Driver

[DavidPaquet]

Hi everyone,

So here is my problem :

I'm using the Oracle JDBC Driver (with JRuby) to talk to a legacy
database.  I also use set_table_name directive since my model doesn't
have the same name as my table.

class Person < ActiveRecord::Base
set_table_name 'BOTS.USERS'


In the console, if I try Person.find(1) I get an error saying that the
table doesn't exit.  The query generated is  : SELECT * FROM
"BOTS.USERS" WHERE ("BOTS.USERS".id = 1)

The thing is that this is not valid, it should be :

SELECT * FROM BOTS.USERS WHERE (BOTS.USERS.id = 1)

How could I fix this ?

[Rails] IE issues (go figure)

[Jeremy]

So, I have this issue with IE.  The code below is from my view and
makes an ajax call to return a list of subcategories.  The form works
just dandy in Chrome/Safari, and Firefox, but IE the Submit button
does absolutely nothing.  Click it--nothing--no error, no nothing.

Anybody have an ideas?



# My view

New Listing

<%= error_messages_for :listing %>

<% form_for(@listing) do |f| %>

  <%= render :partial => "form", :locals => {:f => f} %>

  
<%= f.submit "Create", :disable_with => "Saving..." %>
<%= link_to 'Back', show_my_listings_url(current_user.id) %>
  
<% end %>



# Form partial

<%= f.hidden_field :user_id, :value => current_user.id %>


  Name
  <%= f.text_field :name %>




  Category:
  <% form_tag "", :id=>"categories" do %>
  <% for category in @categories %>
<% if @listing.category %>
  <% if @listing.category.parent == category %>
<%= radio_button "category", :category_id, 
category.id, :checked
=> true %> <%= category.name %>
  <% else %>
<%= radio_button "category", :category_id, 
category.id %> <%=
category.name %>
  <% end %>
<% else %>
<%= radio_button "category", :category_id, 
category.id %> <%=
category.name %>
<% end %>
  <% end %>
  <% end %>





Subcategory:

<%= render :partial => "categories/subcategories", :locals =>
{:subcategories => @subcategories} %>



<%= observe_form :categories,
 :frequency => 0.5,
 :url => { :controller => "categories", :action 
=>
"ajax_subcategories" } %>


  Gender:
  <%= f.radio_button :gender, "Male" %> Male
  <%= f.radio_button :gender, "Female" %> Female



Location:
<%= f.text_field :location, :value => current_user.location %>



  Price
  <%= f.text_field :price %>



  Description
  <%= f.text_area :description %>

[Rails] new controller actions and url_for

[amrita]

Hi,

I just defined a new controller action "list" for one of my
controllers, let's call it "species". To routes.rb, I added the
following entry:

map.resource :species, :member => { :list => :get }

I have a helper method in which I use url_for as follows:

url_for(:controller => 'species', :action => 'list', :params =>
params.merge({:sort => key, :page => nil}))

When I call this helper method from the view, it completely bypasses
the action in the generated URL. I get a URL as follows:

http://myserver.mydomain.org:8080/species?sort=sortparam

What I expect to get is a URL as follows:

http://myserver.mydomain.org:8080/species/list?sort=sortparam

I did a `rake routes | grep list` and I do get the following two
lines:

list_species GET/species/
list
{:controller=>"species", :action=>"list"}
formatted_list_species GET/species/
list.:format
{:controller=>"species", :action=>"list"}

Could someone please point out what needs to be corrected for url_for
to work properly? Is url_for not finding a route for
controller=species and action=list or is there some other problem?


Many thanks!
Amrita

[Rails] rake db:migrate hanging w/ oracle

[Frank Kim]

When I run rake db:migrate w/ oracle it hangs on the db:schema:dump
part and I am not sure why.

E:\work\sandbox\codeReview>rake db:migrate --trace
(in E:/work/sandbox/codeReview)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
** Invoke db:schema:dump (first_time)
** Invoke environment
** Execute db:schema:dump

I think I configured my database.yml correctly.

development:
  adapter: oracle
  host: sid
  #database: sid
  username: foo
  password: 12345
  timeout: 5000

Note that it doesn't seem to matter whether I use host or database.

Also I was able to connect directly to my Oracle DB using Ruby and the
OCI8 driver.

E:\>ruby -r oci8 -e "OCI8.new('foo','12345','sid').exec('SELECT * from
users') do |r| puts r.join(' | ') ; end"

And I did install the activerecord-oracle-adapter.

Anyone know what I'm doing wrong?

[Rails] Re: How to install rubygem-cobbler

[amrita]

Try running a `gem help commands`. You will get an overview of all
things you can do with gem.

Then you can do a `gem help sources` which gives the following :-)

Usage: gem sources [options]

  Options:
-a, --add SOURCE_URI Add source
-l, --list   List sources
-r, --remove SOURCE_URI  Remove source
-c, --clear-all  Remove all sources (clear the
cache)
-u, --update Update source cache

  Common Options:
-h, --help   Get help on this command
-V, --[no-]verbose   Set the verbose level of output
-q, --quiet  Silence commands
--config-file FILE   Use this config file instead of
default
--backtrace  Show stack backtrace on errors
--debug  Turn on Ruby debugging


  Summary:
Manage the sources and cache file RubyGems uses to search for gems

  Defaults:
--list

Now you can add/remove any repositories from your gem sources.

[Rails] Plugins and the test environment

[Nick]

Hi guys. I'm writing a plugin for use in the test environment.
However, when I run ``rake test'' or ``rake spec'', RAILS_ENV is set

How do you configure a plugin to load require a file in the test
environment?

Uh, that would be the 'value' attribute. :-)

I'd suggest re-reading the relevant HTML recommendation. For one
thing,  all radio buttons of a set must share the same name.

See: 

Also, slashes aren't legal characters for an id or name:

That was it. Thank you. I wasted a whole day trying to figure it out but

Yes.  Look at link_to_remote.  You tell it what action to hit and can  
then tell it what div to update or some other custom "sucess" action.   
In your case, I'd replace the "i agree" link with a "thanks" text or  
something.

You're storing too much data. You should generally avoid storing
'real' objects in the session. Instead, just store the ID:

  session[:user_id] = @user.id

...and revivify the actual user object when you need it.

[Rails] CookieStore::CookieOverflow

[Shandy Nantz]

I have recently upgraded to rails 2.1.0. and since I have, the parts of
my app that deal with CookieStore (sessions) has failed to work any
longer. In Crome and most other browsers my code simply fails, IE7 is a
little more forgiving since I can get logged in and then I can only see
certain pages. My session code is pretty simple, a session is created by
saying:

session[:user] = @user

@user being the info collected from the users table, yada, yada, yada.
Here is the error I get when I run my app in IE7:

Thanks Fred,

I realize it was only a deprecation warning but I was hoping it was
what was causing mongrel_service to not work.  Back to the drawing
board I guess.

Setting 'config.active_record.schema_format = :sql' in environment.rb 
appears to have turned dump off altogether.  Was that the expected 
result?

That's all well and good but I'm not sure what is responsible.  Line
455 in inilializer.rb doesn't actually call that it calls a value

The bit about http://www.rubyonrails.org/deprecation is  a generic
message and possibly not relevant. Other than that it should be pretty
clear: that setting no longer has any effect so you might as well just
remove it.

[Rails] Javascript help

[DanC]

I have a blog on my site and would like readers to be able to
recommend comments.

I added an integer column to my comments table called 'agree' and have
a link to a controller which increments the entry in that column by
one on each click.

I just use @comment.increment!("agree") and then redirect back to the
blog.

However, I am paginating the comments and if you recommend a comment
on page 2, for example, the redirect goes back to the default page 1.

Is there a way to increment the table entry using some ajax in the
controller?

I am quite unfamiliar with Ajax and haven't been able to get it to
work.

Thanks

I looked over you XPath article.  Thanks.

But given the table structure noted above, will XPath actually work to 
take the variables that I need in each of the columns and insert those 
into database fields?  I need to locate 3 separate columns and grab each 
of those by row and insert those into a table.  So the html and the 
database table will end up looking the same.

Thanks.

[Rails] gem 1.3.0, netbeans 6.1 "Missing the Rails gem"

[Pablo Q.]

I'm on ubuntu 8.04 and I'm using  netbeans 6.1 with native ruby option.

[EMAIL PROTECTED]:/home/castor# gem --version
1.3.0
[EMAIL PROTECTED]:/home/castor# ruby --version
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]

I'm able to run scripts/console from command:

[EMAIL PROTECTED]:/home/castor/projects/Aflus# script/console
Loading development environment (Rails 2.1.1)
>>

but when I try to run the same from netbeans rails console I get this:

Missing the Rails  gem. Please `gem install -v= rails`, update your
RAILS_GEM_VERSION setting in config/environment.rb for the Rails version
you do have installed, or comment out RAILS_GEM_VERSION to use the
latest version installed.

I checked the configuration of the ruby platform and it looks fine

Any idea?

[Rails] Re: No such file or directory, file_column problem

[Lars-göran Andersson]

I've tried that but no success.
I tried to debug and found that it want to move the temporary directory 
to a new that not exist and then it bailouts. The image column is never 
updated so it is allways nil.

ex:
mv app/public/object/image/tmp/unique_dir_name/ to 
app/public/object/image/development/id/

The destination does not exist. I don't know what rails do in the 
background but normally you can't move a dir to a dir that do not exist. 
Maybe it tries to rename it but I'm sure there are restrictions also 
there...?

I have worked with this for a couple of weeks now.. I never had such a 
problem in my whole programming life (about 30 years).

I'm sure it's a bug - How can I make it work

Who needs loops when you have XPath? You can grab an entire column in
one fell swoop.

  require 'xml'
  doc = XML::Parser.string(html).parse
  column1 = doc.find('/table/tr[position()>1]/td[1]/text()')
  puts column1.to_a

You'll need libxml for that (gem install libxml-ruby). Hpricot is not
XPath compliant enough.

See my XPath article here:
http://markthomas.org/2008/08/22/improve-your-XML-parsing-with-XPath/

[Rails] Re: swfupload with active_record_store? Or any other 'mass'-uploader?

[JWB]

We applied the patch as Peter described and had good results.
Recently, the uploads started failing for a significant number of our
users - they are told to login even though they already
authenticated.  We upgraded to Rails 2.1.1, so I'm looking for a cause
there (though tests succeed).  I'm also looking for browser-specific
behavior, since some users seem to be able to upload successfully.

Please let me know if you've seen any new issues crop up with Rails
2.1.1.

If you are using stuff the ruby schema dumper does not understand you
may just have to switch the schema dumper format to :sql (in
environment.rb), although this does tend to kill cross database
compatibility.

[Rails] schema.dump chokes on RAW type

[Rob Sargent]

I haven't seen anyone mention this yet.

The tail end of the migration process is a call to schema.dump.  Our
primary keys are uuids and these choke schema.dump on both oracle and
postgres.  The latter fails silently (skips three tables) while the
former complains about the RAW(16) in each of the three tables.

Anyone had a similar experience?

Thanks, but I've actually been able to move past the point of parsing

Any thoughts on that would be very much appreciated.

that's the point - with stringscanner you don't need to come up with  
one giant regular expression that gets everything right

as a quick example, this

require 'strscan'
s = StringScanner.new('blah {some_partial arg1:foo arg2:bar} other  
stuff here {otherpartial arg1:baz}')

while s.scan_until /\{/
   puts "start of call"
   puts s.scan /\w+/
   s.skip /\s+/
   while  output=s.scan( /\w+:\w+/)
 puts output
 s.skip /\s+/
   end
   s.skip_until /\}/
   puts "end of call"
end

outputs

start of call
some_partial
arg1:foo
arg2:bar
end of call
start of call
otherpartial
arg1:baz
end of call

A lot of activerecord generates sql fragments - it would be non  
trivial to get around that.
There are a number of ActiveModel (which would abstract out some of  
the relevant bits) efforts going on that may be of interest.

IIRC ruby 1.9 is a bit special - threads are mapped to native threads,  
but there's some giant mutex (IIRC to help compatibility with C- 
extensions that could previously assume that everything was single  
threaded from a native thread point of view) that limits the  
effectiveness of this.

[Rails] Re: ActiveRecord filesystem based backend

[Maurício Linhares]

If you write something that "looks like" active record, the view/form
methods woudn't change, but the association methods (has_one, has_many
and belongs_to) are something deeply rooted into active record and
SQL, they can't be reused in another context.

And, unfortunately (or maybe fortunately), ActiveRecord was built with
the expectation that there is a relational database that understands
SQL at the other side, so it isn't really a "possibility" to do what
you're looking for unless you start to build your own relational
database. Also, Merb is just a web framework, it doesn't have anything
like that.

Hi Maurício,

Thanks for the suggestion.  The problem with using something aside from
ActiveRecord is that you lose all of the view/form helpers, and (i
think) you also lose the has_many helper methods as well, so you'd
ultimately lose a large portion of the utility of the Rails framework.
It seems that IMO all of these helpers should be tied to a Module say
RailsModel or something which ActiveRecord, ActiveResource, etc... would
include.  I don't know how if this would introduce too much indirection
into the Rails framework, but it would make it much easier to introduce
alternative storage mechanisms.  I don't know much about Merb, but maybe
it already contains something similar?

It probably depends on what hosts rails. For example mongrel is most

Actually rails 2.2 will be threaded (rc out real soon now).  
Activerecord itself can be used in a threadsafe way (but not in a  
rails app; i've got a few multithreaded daemons using active record).  
Of course to see the most benefit you'll need a ruby implementation  
with native threads, like jruby.

I don't know if hpricot's result set supports slice, but you could do  
something like this:

doc.search('table td').slice(1,).each do |td_ele|
   .
end

I'm cheating by picking 99 but it's easier than figuring out how  
many results there are.  I'm sure there's a method to simply remove  
that first element in a chain, but I can't think of it.

And you'd want to change that 'search' to match your table specifically.

That's exactly what I've been thinking of, but the real challenge is to

I did change it and it seems to get me a little further. It now 
recongizes that there is a session variable. The issue is that when I 
set the session[:user] = @user, I print out the value when the session 
gets set and it print ths correct value for an id, but when I try and 
reprint it in a before_filter that I have it prints a completely 
different value - not the same id. So I am not sure what is going on 
now? I think the session issue has been taken care off, but something 
else is definetly going on. Thanks again,

[Rails] Re: the performance debate

[Michael Sofaer]

Ruby in general is one of the easiest languages to code in that I've
ever seen.  It also makes it easy to use lambdas in a much more
natural fashion than I've seen before.

Rails is the simplest and easiest framework I've seen for building web
applications.

No one chooses Ruby (or Rails) because it's fast (that would be silly,
since it's not), we choose it because it helps us be more productive,
and spending more on server power to run slow code is cheaper than
spending more on developer time.  If you can find, hire and retain a
group of coders who can work efficiently and elegantly writing website
in C++, that would be a pretty fast website.  I wouldn't try it,
though.

[Rails] Re: display a form with selected values from URL

[Freddy Andersen]

Two ways the good and the bad :

Good:

url:
/author/1/book/new

BookController
new
@author = Author.find(params[:author_id])
@book = @author.books.new


or (not so good)

BookController

@author = Author.find(params[:author])
@book = Book.new
@book.author = @author


Should work too...

[Rails] Managing Plugins/Gems for a specific app

[CPerry]

I am curious to know what the best way (or most ideal way) is to
handle keeping gems/plugins updated for a Rails app that gets updated
quite frequently.

I am currently building an app that will be using like 8 plugins,
along with 9-10 gem packages. I would like to keep these updated as
well as possible while making it easy on myself to do so. Also, I want
to be sure that when deployment time comes, I make that process as
easy as possible as well.

For the plugin side of things, I have been checking out the new
"git_plugins" plugin and it looks promising.
http://www.railslodge.com/plugins/1208-git-plugins

For those of you using a lot of gems/plugins, how do you keep them
maintained and up to date easily?

[Rails] Re: a small doublt

[Michael Sofaer]

Yes, mongrel_cluster is the way to go if you want to handle multiple
concurrent requests.  I recommend nginx over Apache for load balancing
them, if you have the choice.

Threading is indeed hard, but it helps immensely with scaling
problems.   That being said, Ruby threading is not very good at all
and ActiveRecord is not threadsafe, so Rails won't be threaded any
time soon.

Check out Joe Domato's blog for an example of how poorly implemented
and debugged Ruby threading is:  
http://timetobleed.com/ruby-threading-bugfix-small-fix-goes-a-long-way/

Robert is right about how Rails handles concurrent requests (many
instances of application) and correct that Mongrel doesn't spawn Ruby
green threads (a good thing if you looked at the blog post above).
However, most other web frameworks I know of don't do it that way.
PHP and J2EE will have a master process that spawns child threads to
handle requests, as does nginx.  This lets the OS handle load
balancing, and switch out threads that are blocked (usually waiting
for DB calls to return).

It would be better if Rails could do that but it can't.  It's not a
huge deal, unless you are running a very high-traffic site; just put
up a Mongrel cluster and you will be fine.

I don't know if the session_key needs to match your app name. You could

[Rails] How to let a user render a partial?

[David Trasbo]

Hi all,

I'm currently doing a little CMS system in Rails and I would like the
user/administrator of a site to be able to render partials on pages. I
have a Page model with a content attribute. Inside that attribute I
would like the admin to be able to put something like this:

{contact_form submit:"Submit now!" reset:"Reset form"}

This is just an example, but this should then render a partial like
this:

render :partial => "widgets/contact_form", :locals => {:submit =>
"Submit now!", :reset => "Reset form"}

I have been trying to make up a regular expression to approach this, but
I'm not very good at it. It looks like this:

/\{(\w+) (\w+):(.+)*\}/

But it is hard to make it respect multiple arguments, if you know what I
mean. Now, if any of you have an idea of how to finish this regular
expression, or maybe know a different solution of how to let the admin
render partials "dynamically", I would appreciate if you'd let me know.

[Rails] Re: Problem with DateTime in query

[Bosco So]

Ryan Bates' screencast on this topic - http://railscasts.com/episodes/108
- has more details about delaying evaluation of the condition with a
lambda (including optional argument).

How weird, I literally just watched his screencast before reading this
question.

Sorry I meant to say a separate form on the same page.

[Rails] Re: Update only selected columns

[Robert Walker]

This is a common issue, and not with just Rails applications. You best 
bet is to design your user profile update page to not send the password. 
Either provide a change password page, or a separate for used 
specifically to change the password.

Others may have other ideas on how to deal with that. I suggest looking 
around at other profile update pages and see how they handle it.
