[Rails] Re: Spree on Windows

[MaD]

you got a problem with slashes / backslashes as directory separators.
unix uses a slash (and that is what rake expects) while windows uses
backslashes (which are interpreted as escape-characters).
i'm not on windows, so i can't really tell you what to do to fix it,
but i hope i could point you into the right direction to google a
solution.

[Rails] general iplementation question Do I need polymorphic here

[Sijo Kg]

Hi
I have to create a request for an organization and also to create a
request for many Contacts..Now what I do is treating all these in a
single table say request and it has all the fields like
organization_name, contact_name etc Here company_name is at atime one
for a request but contacts are more than one say primary_contacts,other
contacts etc..what my question I tried here a polymorphic relation here
like
class request true
end
class Organization :request
end
class Contact :request
end

But I think this not correct since it makes sense like
orgnization.request  and
contact.requests

  But what I need is the reverse way..(Am I right?)..Please help
to properly arrange this

Thanks in advance
Sijo

You should explore will_paginate plugin which is what I intend to do in a
few days when I get to my problem.

[Rails] Write checkbox values in database

[Swarna Priya]

Hi,

I am new to rails. Any support from your side would be very helpful.

I have a model called child and another model called childcategory. I
have given the code in app/views/children/show.html.erb of child.

<% remote_form_for [...@child, Childcategory.new] do |f| %>

<%= f.label :body, " Allowed Categories " %> 
<% for category in @cat do %>
   <%= check_box 'checkbox', category.categoryname %> <%=
category.categoryname %>
<% end %>
  
 <%= f.submit "Update Settings" %> 
<% end %>


NOw the check boxes are displayed from another model called
Filtercategory. When the user checks a check box in the above view, i
want the check box value to be inserted in a model called Childcategory.
The controller code is as follows.

app/controllers/childcategories_controller.rb

class ChildcategoriesController < ApplicationController

def create
 @child = Child.find(params[:child_id])
 @catlist = @child.childcategories.create!(params[:childcategory])

 respond_to do |format|
   format.html { redirect_to @child }
   format.js
end
   end

end

But  when i submit the "Update Settings" button, a new record is created
with childid but the category name in the check box is not saved in the
table.


Can you say whats the issue. I couldnt solve this.


Any suggestion would be really supportive.

[Rails] Re: HowTo install plugins from github?

[Sandeep Sagar]

The http counterpart  is what I was searching for but could not find.

I will try to document my travails as a noob to RoR on WinXP and put it on
the wiki.

 

Since I installed the git client and installed my keys, I have been able to
get the plugins I needed.

 

Next up - I will go for will-paginate and see how my "new found" wisdom
helps me :-)

 

Thanks all, as I have been able to move at such a fast pace with all these
plugins as compared to any other stack I know of and I have worked on both
the Java and the .net stacks...

You don't need svn to use rails but then you wouldn't be able to
install plugins hosted via svn.
To say rails requires you to install git is back to front: people
started using git to host the plugins they developed and so some nice
person extended script/plugin to be able to install plugins hosted in
such a manner. If it's anyone's "fault" it's the plugin authors for
using git to host their plugins :-)

[Rails] Re: How to install Rails on CentOS 5.2

[Paryank]

Thanks phil,

But I still have the same error.

I have removed my existing ruby package by:

yum remove ruby

And then followed the steps you have mentioned. But when I run command
to install rails first it try to update rubygems. It was taking very
long time. So I have updated rubygems by the following command:

gem update --system

After gem is successfully updated, I tried again to install rails. But
it was giving the same error again:

ERROR:  While executing gem ... (Zlib::DataError)

[Rails] Using same partial with diff ajax requests.

[David]

Im wondering what the best design implementation with DRY in mind in
the following situation.  I have a number of situations where I am
rendering the same partial with different ajax requests.  For example,
I have an inbox table and I have to link_to_remotes.  One links to
viewing all messages and another links to show a single message.  Im
wondering, does it make sense to use the same partial and create a
variable in the controller which could be used in an if else statement
within the view.  like:

def show
@type = "show"
page.replace_html "inbox_message", :partial => 'message', :locals =>
{:type => @type}
end

def index
@type = "show_all"
page.replace_html "inbox_message", :partial => 'message', :locals =>
{:type => @type}
end

then in the _message partial i could have somehting like:
if @type == "show"
  only show one message
else
  show all messages
end

Is there a better way to do this?  Would just creating two different
partials be any better?  What about any performance issues?

Thanks, Dave

[Rails] GlassFish Portfolio Announcement

What does the new GlassFish Portfolio
(http://www.sun.com/software/products/glassfish_portfolio/index.jsp?cid=e8021my),
especially the web stack mean for Ruby and Rails ? It would be nice to
have a standard up to date stack to deploy on.

Also, they mention mod_ruby - don't they mean mod_rails ? Maybe they
really want us to use JRuby on the "Enterprise Server" component.

I was able to figure this out...If the record was not successfully 
audated because of a validation error, I needed to render :action => 
:edit.

It now shows the errors nicely.

[Rails] update + validation error

looks like this

[Rails] Re: RJS alert with a prototype div

[Chris Habgood]

Ok, thanks.  What I am really trying to do is this which I have been banging
my head against:
How do I get the dom id to come in?
The 2nd line prints properly in firebug and shows the value but the first
line just has "#...@next" in it not the value.
Same idea as the alert but an IF condition I think.

page << 'if ($("#...@next}").value == "APS") {'
page[:"#...@next}"].replace_html 'moo'
page << '}'

to work it out and play with it but it most certainly seems to be a
help. Again thanks for the effort.

@Randy,
Thank you for the direction you gave me. I def appreciate that you
took time out to go back and forth with me enough to get my whole
thought out. It was a huge help.

Now i think im going to try my hand at making a stripped down doc-
database implementation in ruby... couchdb looks awesome but waaay too
heavy for my needs.

thanks for the pointers guys

[Rails] Re: RJS alert with a prototype div

[André l . Leal]

Guess you are right... I thought that it might work...

anyway.. you could just stay with raw javascript:

page << "alert($('test_alert').value);"

But I'll try to find a better solution...

[Rails] Re: sparse tables seems to be an impossible term to search on google

[Pardee, Roy]

I suspect something like this could work--may be worth a shot.

# Models
class Table < AR:Base
  has_many :column_groups, :order => 'cg_num'
  has_many :rows, :order => 'rownum'
  def columns
self.column_groups.map {|cg| cg.columns}
  end
end 

class ColumnGroup < AR:Base
  belongs_to :table
  has_many :columns, :order => 'col_num'
end

class Column < AR:Base
  belongs_to :column_group
  has_many :cells, :order => 'col_num'
end

class Row < AR:Base
  belongs_to :table
  has_many :cells, :order = 'col_num'

  def get_cell(col)
# there's almost certainly a faster 
# way to do this, but this is all that 
# comes to mind.
cells.each do |cell|
  return cell if cell.column == col
end
return " "
  end

end

class Cell < AR:Base
  belongs_to :row
  belongs_to :column
end

# Controller
class TableController < ApplicationController
  def show
# :include may be useful here if perf is an issue
@table = Table.find_by_name(params[:name])
  end
end

# View

  
<% @table.column_groups.each do |colgroup| %>
  ><%= h colgroup.name %>
<% end # colgroup %>
  
  
<% @table.columns.each do |col| %>

<% end # col %>
  
  <% @table.rows.each do |row| %>

my bottleneck at the moment is "how do i properly merge all this quasi- normal 
data into an array FROM a rails find"... i can find all the sheets.. i can 
"find" all the sheets columns, i can find all the columns data... but i cant 
merge them into one cohesive structure which can then be easily iterated over 
ie:

please take this for the psudocode that it is.

--table--
  --thead--
--tr--
  columngroups.each do |columngroup|
  --th colspan=columngroup.column_count--
columngroup.name
  --/th--
  end
--/tr--
--tr--
  columns.each do |column|
  --th--
column.name
  --/th--
  end
--/tr--
  --/thead--
etc...

my main problem is that the find returns the columns, columngroups etc... are 
all in random order... i think i need them returned as a key/value so i can 
align everything properly.. but i dont know.

a sheet is just a way of giving all the columns/rows something to say "hey, 
this is my parent object"...

You don't need svn to use rails but then you wouldn't be able to
install plugins hosted via svn.
To say rails requires you to install git is back to front: people
started using git to host the plugins they developed and so some nice
person extended script/plugin to be able to install plugins hosted in
such a manner. If it's anyone's "fault" it's the plugin authors for
using git to host their plugins :-)

Hi
I am a noob on RoR and I will agree that this git dependency came in from
the left field for me too!:confused:

All the documentation I saw about plugins blithely says use the following
command to install plugin -

rubby script/plugin install acts_as_tree
and it works

But when I went to try to install acts_as_authenticated and used -
  ruby script/plugin install
git://github.com/gundestrup/acts_as_authenticated.git
  ruby script/generate authenticated user account

I got the error authenticated not found!

working back I found that nothing had been installed in the plug-ins
directory. AND there was no error message  during the install either.

After a lot of hunting on forums, I found this post which says that I need
to install this git client! That is not consistent.

:thinking:A gem (git-gem?)dependency I could understand.  but a whole new
client to keep track off?  Rails doesnt need you to install svn or Perforce
or anything right?  You should need these only if you are going to make
changes to the plug-in

So thanks for posting this as now I am off to install git  but want to share
my thoughts.

[Rails] Mapping a directory into a database table

[elioncho]

Guys I am trying to display a series of directories located on the
server in a tree view. I have seen some solutions for displaying a
tree view based on data on a database but I need to first map my
directory into the database. How can I do this? Also, I want to take
the opportunity to ask if what component to use to display the tree?
(YUI treeview component?)

Thanks,

[Rails] what does config.threadsafe! actually do?

[Jonathan Rochkind]

Does anyone know what config.threadsafe! actually does, what effect(s)
it has?  I'm even sure where to go looking in the source code for
effects of a config variable like that, but if someone has source to
recommend, I'll give it a shot (although I sometimes have trouble
comprehending AR source, I must admit).

I know it tells Rails to do concurrency request handling. Okay, so far
so good. But I suspect it does other things to to them make Rails behave
differently to support concurrent request handling, rather than simply
remove a mutex around the event loop or whatever.

I ask this because, while I'm not actually interested in concurrent
request handling (don't need it), I _do_ use threads in my Rails app for
other purposes. (Dealing with long-running processes, dealing with
talking to slow external web services).  I'm actually surprised that
nobody else seems to have a use case for this, but in my app it's pretty
crucial.  So I'm trying to figure out what Rails 2.2 can do for me, and
how I'll have to change my Rails 2.1 code to deal with it, etc..  The
changes around supporting threading more intentionally are potentially
good, but the only documentation or writing I can find on it (and very
little of that) assumes you are interested in concurrent request
handling.

Since I'm not, I don't neccesarily want to call config.threadsafe!. But
I'm wondering if there are side effects of config.threadsafe! that I
might want to trigger myself, to make Rails happier about handling
multiple threads (possibly with AR) even without concurrent request
handling.

Anyone have any info to point me to?

[Rails] Mongrel problem

[Miquel Oliete]

Hi there

I have installed mongrel using rubygems and I have filled the mongrel
configuration file in my rails config directory, which is:

cwd: /var/www/my_http_dir/
log_file: log/mongrel.log
port: "8100"
environment: production
address: 127.0.0.1
pid_file: tmp/pids/mongrel.pid
servers: 2

The problem is that when I try to start mongrel using the command line
order 'mongrel_rails mongrel::start -C config/mongrel_cluster.yml'
appears this error message

** Ruby version is not up-to-date; loading cgi_multipart_eof_fix
** Loading settings
from 
/var/www/ktala/mob1970.org/cheatsheetsandrecipes/config/mongrel_cluster.yml 
(they override command line).
!!! Unknown configuration setting: servers
mongrel::start reported an error. Use mongrel_rails mongrel::start -h
to get help.


Can anybody tell me what is happening? Why servers params is not ok?


Thanks in advance

Regards


Miquel

[Rails] Re: Ultrasphinx - field is invalid - can't get :filters to work

[Mrknife]

I was able to get a 'filter' to work...

basically I used the :concatenate option

is_indexed :fields => ['title','description','created_at'],
  :concatenate => [ {:fields => ['topic_id'], :as
=> 'video_topic_id'} ],
  :delta => {:field => 'created_at'}

Then I was able to run this.

Ultrasphinx::Search.new(:query => "london video_topic_id:
17", :class_names => "Video")

This is in no way ideal...
But I did manage to return the result set I wanted.

[Rails] Re: Constants not visible in controllers or models

[Peter Hickman]

Sorry, disregard everything I said. I'm having a blond moment. My  
initialiser scripts were actually .yml files rather than .rb files. So  
the line

AVATARS_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/avatars.yml")

didn't actually do anything. Didn't error either but it's all my fault.

Sorry to waste your time

[Rails] What's the pattern for modularizing / sharing your code?

[Duane Morin]

Ok, this is the first time I've run across this, but I think they're
good problems to have :).

I've got a web app out in production.  I've also got a tool for internal
use that manages the reporting on that application.

Problem #1:  What's the best practice out there for sharing the model?
They are entirely separate web apps with entirely different users,
environments, and purpose - but they both manipulate the same business
model.  Surely there is a way to avoid repeating myself?


Problem #2:  With the success of the first production webapp, the boss
said "Ok, now tell us what it would take to do the exact same thing for
our other, differently-branded web site."  Ummmshort of "clone all
the source code" I was a bit stuck for an answer.  Here it seems like
there'd be even more overlap, but I'm not sure about the reality - it
would be all new views, but also at the very least some new
configuration to differentiate it from its twin in the database.  Is
there a better answer there?

Random guesses: assuming that the page contains more than just this:
- are all dom ids unique
- have you got nested forms ?

[Rails] ActiveSupport::Cache vs. others?

[Marc Byrd]

Hi,

We are building and using a new caching gem.  We would like to figure out
how to make this most friendly and easy for both existing projects and new
projects to use.  I'm guessing the best way to get used in new projects
would be via subclassing the ActiveSupport::Cache::Store class?  Is this
expected to be the primary way to use a cache going forward?

What about gems that may be widely used in existing projects like cached_fu,
memcached, etc. ?   Are these expected to be rolled in through
ActiveSupport::Cache over time?

If you had to chose one cache interface to speak (e.g. drop-in replacement,
small constructor diff only, or config diff only), which one would you
suggest?  And if only two, which two?

Thanks,


Marc

[Rails] form_remote_for NOT passing param: I want put and I get post

[Raimon Fs]

Hello,

I'm struggling my brain with this ajax issue ...

Basically I have a form for creating records, and I want to submit it
using Ajax.

On previous versions of RoR (2.0.2) it was working, but the same methods
doesn't work on 2.2.2, and I started to make changes and changes and
read forums and the api, but no way ...

<% form_remote_for (:expedient, :url => {:action => 'create_ajax'},
:update =>'div_listd') do |f| %>



  Referencia
  <%= f.text_field :reference %>
  <%= submit_tag "Añadir" %>



<% end %>

In the development.log I only see the token param:
  Parameters:
{"authenticity_token"=>"c5fb066b9a3370e15f94154cc2140759d40f079c"}


the html source code is this:






  Referencia
  
  





I see that the method is post, I think it should be 'PUT' to pass the
variables in the params ... or I'm wrong in this assumption ?

I tried to add the :method => :put but no way . sure I put it in the
wrong place :-)

thanks again!

[Rails] restful authentication: integration testing

[itsastickup]

Hi,

Anyone know how to do integration testing with the "Restful

sess.extend(AuthenticatedTestHelper); #

[Rails] Re: sparse tables seems to be an impossible term to search on google

[Matt Jones]

To me, there are two possibilities: either switching to a less-
normalized design (serialized columns) or
a different database idea entirely (CouchDB, for instance).

I haven't used CouchDB personally, but check it out:

http://couchdb.apache.org/ (the main project)
http://github.com/arunthampi/activecouch/tree/master (an ActiveRecord-
like wrapper)

It's a "document database", which can store arbitrary key-value pairs
for each "document".
Sounds like it might be a better match for what you're trying to do.
--

Staying within Rails, if you don't have a need to search by specific
column values (which you haven't
mentioned), you could just store the data in a single serialized
field:

Sheets
- id (int)
- name (string)
Columns
- id (int)
- sheet_id (int)
- column_group_id (int)
- name (string)
ColumnGroups
- id (int)
- name (string)
Data
- id (int)
- sheet_id (int)
- tool_number (string)
- row_data (text, serialized)

Then keep the data in Data#row_data, as a Hash of (column_name =>
value) [or column_id => value] pairs.
That would keep all of the ToolNumber stuff grouped together.

BTW, if you need columns in a particular order, take a look at
acts_as_list - it should work great for what
you're doing here.

In conclusion (this has gotten rather long), I'd recommend first that
you take a look at CouchDB. It seems
like a much better match to the idea you're looking for. The
serialized-column approach is a little more of a
hack, but should work if nothing else is possible.

[Rails] Re: sparse tables seems to be an impossible term to search on google

[frankjmat...@gmail.com]

ive considered it but i still come back to the fundamental problem of
sucking out all the information contained in one "sheet" and
organizing it into a manageable hash or array or whatever would work
best. i think thats where my greatest problem lies.. taking the info
and turning it into one meaningful structure i can loop through.
having everything "sparse" (im using the term to mean.. not every
column of every row will be filled in) seems to make it hard for me to
just merge arrays...

i think...

its getting harder and harder to describe hehehe.

[Rails] Re: test if an external url is valid before redirecting to it?

[Max Williams]

That's perfect, thanks Andrew.

You're probably right about testing the validity at the point of adding 
it rather than (or as well as) the redirect.  I think i'll put a remote 
test button next to the input field, and maybe call it automatically on 
change of the field.

Anyway, thanks again.

I am not an expert by any means on this, I am just trying to offer a

That code *may* work, but it will probably confuse the gem loader a
little. The
problem you're having is that the 2.2 vendor gem handling stuff isn't
loaded
until the environment is; if your rake task looks like this:

task "do_something" => :environment do

end

Then move the require line *inside* the task, which should pick up the
unpacked gem.

Hope this helps!

Watch the validity of the url - www.google.com is not valid
http://www.google.com also won't work, http://www.google.com/ will

I wouldn't do this at the point of redirection, I would do it at the point
of saving the redirection url

[Rails] Re: Anyone familiar with Bort? How is it supposed to be used?

[Freddy Andersen]

You are right Bort is not a noob app, but its very easy to setup.



* Download and unzip Bort
* Edit the database.yml and the settings.yml files
* Changed the default password in the bort migration
* Edit the REST_AUTH_SITE_KEY in each of the environment files
* Rake db:migrate
* Have a brew and celebrate

That's from the Bort site. Is there something in particular that is
breaking? I have used Bort and other apps like it many times as the
base for my applications just to get a jump start on the basic
functions...

Thanx Fred. But the thing is that database is created in DB using the 
same database.yml and the same database.yml is not working for scaffold.

I have seen, there is no issue with spaces.

Did you solved your problem ?

I'm having the same trouble, but in my source html page I can see the

No matter wich action I I call, it never fires. I suppose Rails is

any ideas ?

[Rails] config.default_timezone vs. config.time_zone

[James Byrne]

In config/environment.rb are these statements equivalent?

config.default_timezone = :utc
config.time_zone = "UTC"

If not, then how do they differ in effect?

[Rails] Re: executing a generator on the browser

[Rey9999]

My advice stands.
You'll need to call the generator using system
e.g.: system(script/generate blah blah parameters here)
selecting a target directory could be another story, if this generator
does not accept a target as a parameter. how about moving the
generated files after you've run the command?

Regards,
Rey

[Rails] test if an external url is valid before redirecting to it?

[Max Williams]

In our site, users can have a url associated with their account to which
they are redirected when their login expires.  This can differ from user
to user, and is prone to being mis-copied, or the sites in question not
being there any more etc.  I'd like to test if the url is valid before
sending the user on to it.

So, i want, in the controller, to do something like this -

if external_url_is_valid?(user.expiry_url)
  redirect_to user.expiry_url
else
  redirect_to "our_default_expiry_page"
end

Can anyone tell me a nice, simple and efficient way of doing the
"external_url_is_valid?" bit?

[Rails] Re: Active Record Associations

[Rey9999]

If I understand correctly what you need, a computer may belong to many
users and one user can have many computer, right? same for phones, I
assume.

In this case, the relationship is :has_and_belongs_to_many, but you do
not need the classes OwnComputer and the other one. you just need two
tables (without id) which will contain, for each record, a couple of
id identifying one coupling (user-computer for one table, user-phone
for the other).
have a look at:
http://wiki.rubyonrails.org/rails/pages/has_and_belongs_to_many
for naming conventions.

Regards,

Rey

[Rails] How to achieve STI has_many :through referencing to the same STI

[satynos]

I have the base Content model from which all the types of the contents
such as page, post, asset descend as follows:

class Content < ActiveRecord::Base
end

class Page < Content
end

class Post < Content
end

class Asset < Content
end

Now I am trying to accomplish relationships between all these contents
using a relationship table as follows:

class Relationship < ActiveRecord::Base
  belongs_to :content, :polymorphic => true
  belongs_to :target, :polymorphic => true
end

Accordingly I updated the base models to reflect the relationships as
follows:

class Page < Content
 has_many :relationships, :as => :content
 has_many :posts, :through => :relationships, :source
=> :target, :source_type => "Post"
 has_many :assets, :through => :relationships, :source
=> :target, :source_type => "Asset"
end

class Post < Content
 has_many :relationships, :as => :content
 has_many :pages, :through => :relationships, :source
=> :target, :source_type => "Page"
 has_many :assets, :through => :relationships, :source
=> :target, :source_type => "Asset"
end

class Asset < Content
 has_many :relationships, :as => :content
 has_many :pages, :through => :relationships, :source
=> :target, :source_type => "Page"
 has_many :posts, :through => :relationships, :source
=> :target, :source_type => "Post"
end

But when I try to access @page.assets, I am getting empty array. In
looking at the log file, I see the reason being the following query:

SELECT `contents`.* FROM `contents`
INNER JOIN relationships ON contents.id = relationships.target_id
AND relationships.target_type = 'Asset'
WHERE (`relationships`.content_id = #{id} ) AND (`contents`.`type` =
'Asset')

The problem is due to the highlighted portion of the query. When the
active record saves a relationship, it is saving the content_type and
target_type as "Content" (the base model class) instead of the actual
content type "Page" or "Post" or "Asset".

Is there any way possible to achieve what I am trying without any
plugins? How can I tell ActiveRecord to save the content_type and
target_type of the relationship with the actual class name instead of
the base class name?

BTW: I looked into has_many_polymorphs, but it doesn't quite solve my
problem.

Thanks in advance.

Because ActionController::NoMethodError doesn't exist. It's just plain  
NoMethodError (possibly ::NoMethodError but I don't think that's  
needed here)

[Rails] Re: sparse tables seems to be an impossible term to search on google

[frankjmat...@gmail.com]

my bottleneck at the moment is "how do i properly merge all this quasi-
normal data into an array FROM a rails find"... i can find all the
sheets.. i can "find" all the sheets columns, i can find all the
columns data... but i cant merge them into one cohesive structure
which can then be easily iterated over ie:

please take this for the psudocode that it is.

--table--
  --thead--
--tr--
  columngroups.each do |columngroup|
  --th colspan=columngroup.column_count--
columngroup.name
  --/th--
  end
--/tr--
--tr--
  columns.each do |column|
  --th--
column.name
  --/th--
  end
--/tr--
  --/thead--
etc...

my main problem is that the find returns the columns, columngroups
etc... are all in random order... i think i need them returned as a
key/value so i can align everything properly.. but i dont know.

a sheet is just a way of giving all the columns/rows something to say
"hey, this is my parent object"...

[Rails] Anyone familiar with Bort? How is it supposed to be used?

[Ralph Wood]

Noob here, obviously.

I checked Bort out and was left a bit confused. It seems everything I
try to do either breaks or interferes with some of its default
configurations and plugins.

I realize Bort is intended for people who already know their way around
an app, and what they are doing, and not as a shortcut for noobs, but I
am really intrigued, and would like to have a better idea of how to even
begin playing with it.

So if someone could provide a quick sort of "checklist" of how to get
things rolling properly with it, I would appreciate.

[Rails] Re: sparse tables seems to be an impossible term to search on google

[Randy Kramer]

(top posting and not snipping very much so that somebody else can pick 
up the thread)--I think I'm out of my depth trying to deal with the 
best (i.e., fastest) way to deal with your data in Ruby/Rails.  (If I 
was to hazard a guess, I might try dealing with each table as an array, 
just for the sake of speed.)

OTOH, if this is a rails application, presumably there is a client and a 
server (and TCP/IP communication between them)--is the database 
processing on the server really the bottleneck?

At least one more comment interspersed below.

Without a lot more thinking, I don't fully follow the above description.  
I guess "sheet" is the first thing that puzzles me--is a sheet a table, 
or is there a table containing up to 5000 sheets?  (Maybe the "schema" 
you list below would answer that and my other questions, but it would 
probably take me a while to puzzle it out--more time than I have atm.)

If I really wanted to understand it, I'd ask for an example using "real" 
data--sheets, columns, and rows just confuse me (would that be 
metadata?).

[Rails] Re: executing a generator on the browser

[bbtosurf]

Hello Rey and thanks for your answer. This generator belongs to a gem.
So the idea is that when a user is browing my website and click on a
specific button this generator should be executed and directory of
files is created on his personal folder on the server (this folder is
created when a user signs up)

Thanks,

Elías

[Rails] Re: sparse tables seems to be an impossible term to search on google

[frankjmat...@gmail.com]

ive toyed around with just using txt files but my limited
understanding of "proper technique" in dealing with them makes them
just as cumbersome...

im very familiar with normalization and if it was practical (and the
cost didnt outweigh the benefit) id make sure everything was
absolutely 6NF and then some... but coulda, woulda, shoulda... its not
practical.. the best im shooting for is 3NF or 4NF but its not a
stringent requirement...

i guess you could say i know my way around databases, im just lost
with trying to implement this in a ruby way. my database breakdown
will probably look as follows (i think, unless someone can point me in
a better direction)...

over time there may be 5000 sheets... each sheet may have up to 20
columns. each column will eventually belong to exactly one group. each
group may have up to 400 "rows"... .. so if a sheet has 4 columns and
2 groups like my prev. example and is filled to capacity... theres
going to be 400 rows for each set of groups... 800 rows... they need
to then be translated into one cohesive unit for display. the final
display will have all 4 columns separated into groups and "merged" so
all the "toolnumbers" line up in rows.. displaying only 400 rows.

i **think** i understand the database side.. im lost on the ruby
implementation (or any implementation).. is there a "most effective"
way to construct my relationships?

Sheets
- id (int)
- name (string)

Columns
- id (int)
- sheet_id (int)
- column_group_id (int)
- name (string)

ColumnGroups
- id (int)
- name (string)

Data
- id (int)
- sheet_id (int)
- column_id (int)
- tool_number (string)
- value (int)

then i'll have a possible array as such for a query like:
select tool_number, value from data where sheet_id = x

whats an effective way to iterate over the returned dataset and sort
it out into its corresponding columns column groups and rows... im
seeing a join in my head but i dont know on what.

:(

hopefully my problem is becoming a little more clear... but the deeper
i dig the more i suspect theres an elegent solution im not advanced

[Rails] Active Record Associations

[James Bond]

I have tables:

users (id, name)
computers (id, name)
mobiltelefons (id, name)

OwnComputers (id, user_id, computer_id)
OwnMobiltelefons (id, user_id, mobiltelefon_id)

So is it  has_many :through or has_and_belongs_to_many or what?

I only need to search one "own" table at time:
All computers that user "xx" owns OR
All Mobiltelefons that user "xx" owns OR
who owns mobilitefon "zz" OR
who owns computer "yy"

So...

class Computers < ActiveRecord::Base
  has_many :OwnComputer
  has_many :user, :through => :OwnComputer
end

class OwnComputers < ActiveRecord::Base
  belongs_to :Computer
  belongs_to :User
end

class Users < ActiveRecord::Base
  ???
end

class Mobiltelefons < ActiveRecord::Base
  ???
end

class OwnMobiltelefons < ActiveRecord::Base
  ???
end

i once had a similar problem. in my case i wanted to skip some code

Create your own class that inherits ActiveRecord::Migration and use

Well, I sort of stand by my original response then.  I mean, when you 
have an unnormalized relational database and responses are too slow, 
the typical recommendation (I think) is to normalize the database.  I 
won't try to explain that here, you need to look it up.  (Maybe someone 
can explain it (and how to do it) simply, but I can't, at least not at 
this time.)

Normalizing the database is not the only way forward however, and I'd 
ask how much data you have.  For my only (in progress) application, a 
relational database is just not the right fit, and in general slows 
everything down (in comparison to plain text files and "ordinary" (and 
indexed) searches).  (My application has plain text files with 
(currently) up to 5000 variable length records per file, totalling on 
the order of 10,000,000 characters per file.  At them moment I have 
about 12 such files, although only two are that big.  I plan to scale 
to files as big as 100,000,000 characters without switching to a 
relational data base (which I'm sure would slow down my application).

How much data will you have in this(these) table(s)?  For a low quantity 
of data, maybe even a spreadsheet "technology" would do the job?

Other solutions, like a separate machine (server) to handle the database 
could help as well.  I guess someone would need more information, 
specifically about the quantity of data involved (now and in the 
future).

Hey guys, i've not tested it, but:

1. you are able to set environment variable when runing rake from 
commandline

2. you are able to test against ENV[:variable] in your code.

3. problem solved? :)

here is the inspiration:

[Rails] Re: sparse tables seems to be an impossible term to search on google

[frankjmat...@gmail.com]

Once again I hit send a little premature.

What I'm really looking for is a technical explaination of the correct/
incorrect way to acheive this... I'm sure it's a problem that someone,
somewhere had to solve once before and I've been trying to reinvent
it, as i said - with separate tables for the columns, column groups,
rows, tables... but in the end - merging all the tables together and
iterating over everything just seems to take forever... not in the
least bit efficient or reliable.

[Rails] Re: sparse tables seems to be an impossible term to search on google

[frankjmat...@gmail.com]

ah, thank you. any response - even yours - feels good. i realize this
isnt the most thoroughly explained post so here goes.

i have a need allow my program to create and store variable column
data much like the sense of a spreadsheet where at any given time,
only a handful of columns will be accessed - but over the lifetime of
the "spreadsheet" (table seems too broad a term for me), all the
columns and all the rows will slowly become filled. if you would
imagine this scenario:

UserA defines/"creates" TableOne.
TableOne has ColumnOne, ColumnTwo, ColumnThree, ColumnFour.
UserB needs access to ColumnOne and ColumnTwo recognized as
ColumnGroupOne.
UserC needs access to ColumnThree and ColumnFour recognized as
ColumnGroupTwo.

now the row count is generally fixed (not truely fixed but not
sporatic) but isnt known in advance. rows are not identified by their
primary key but by another column called "ToolNumber" which is
specified in the ColumnGroup.

UserA and UserB may be modifying a record that names the same
ToolNumber and ultimately, upon the table/spreadsheets completion -
will all be consolidated into one master sheet which contains all Rows
and ColumnGroups merged into one table displayed for the user or print
or whatever.

Hopefully that gives you a better idea of what im asking for.

Sparse tables may be a meaningful term but I am most certainly
stretching the definition so that may be a point of confusion and I
understand that.

Many thanks,
- FJM

[Rails] Re: executing a generator on the browser

[Rey9999]

I'm not sure of what you're asking, but if this 'generator' is an
application residing on the server running your web application, you
can call it using the ruby command system('executable_name').

[Rails] Scaling Rails Screencasts

[Gregg Pollack]

Hey guys,

   If you're interested in learning more about how to properly Scale a Rails
app, I just released 7 free Scaling Rails Screencasts which you can view
here:

[Rails] Re: sparse tables seems to be an impossible term to search on google

[Randy Kramer]

On Tuesday 10 February 2009 12:05 am, frankjmat...@gmail.com wrote:
> ive asked this question a half a dozen different ways and none have

(Just an aside--is everybody switching to top posting--where's the 
context, what's the question--must I read the rest of the post to find 
the question?  (Sorry, I'm in a funky mood, on another list I read, 
some guy quoted a long post, and somewhere in the middle of it posted a 
short phrase response (less than a line).  What a pain.)

Anyway, after skimming the rest of the post, I'm not entirely sure of 
your question:

   * do you want pointers on how to search for "sparse tables" on 
google, or
   * do you want help on storing "variable column sparse tables"--ahh, I 
didn't see the variable column part the first time I skimmed

Anyway, before I saw that, I was going to say that a relational data 
base (which is what Rails uses (iiuc, something like MySQL, Postgresql 
(??), or whatever, is something like a sparse table because tables 
don't have to be "complete"--for example, if the key field is some 
numerical index, you can have records 001, 006, and 046--you don't have 
to have a line for every record from 001 thru 046.

But I guess that's not what you mean by "variable column sparse tables".  
So what do you mean?  You mean where (starting with my sparse example 
above ;-), some records (lines) do not have a value for every column?  
Maybe something like this:

View in fixed font:
keylastname   firstname   height  weight   hatsize   shoesize
001  Mattia   Frank 5'11" 7 1/4   10 
006  Doe  John   5'6"  165
046  Jane   5'5"

If that's what you're looking for, as far as I know, tables like this 
can exist in a relational data base and not really cause any problem.  
A pedant would (I think) make some comment about the data not being 
fully normalized, and maybe some slightly less efficiency that would be 
experienced if you had many (i.e., thousands, millions) of such 
records.

OTOH, normalizing the database (typically) takes effort both by the 
programmer / database administrator and in the database itself (running 
queries or whatever to actually accomplish the normalization, so for 
small quantities of data (I would argue that) it is not efficient to 
normalize the data.  

> > afaik i need a table for my rows

I haven't thought through what the above is about, but at a quick skim 
it sounds like the kind of tables and effort that would be needed to 
normalize the database.  Like I said, for some definitions of small, 
this is counterproductive for small quantities of data (imho).

If your question is something else, maybe you can clarify.

[shahroon ali]

Hi everyone,
I was just trying to catch some exceptions in my app,

  rescue_from ActionController::NoMethodError, :with => :show_error

private

  def record_not_found
render :text => "404 Not Found", :status => 404
  end
  def show_error(exception)
render :text => exception.message;
  end


and was quite successful but for "NoMethodError" I am trying the same but It
isn't working at all. Can anybody help me?

[Rails] Constants not visible in controllers or models

[Peter Hickman]

Hi,

I might be being a bit thick today but I have a problem that I can't  
seem to shake.

I have some configuration data in a yaml file that I load with an  
initializer.

AVATARS_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/avatars.yml")

The information includes where to save upload files and other stuff so  
it is needed in several places. One of the controllers can reference  
AVATARS_CONFIG, but the model, avatars.rb cannot. So I have to have  
the same line in any controller or model that needs it. Which looks to  
be very messy not to mention inconsistent - some places need it, other  
don't.

I've tried to make them global, ie $AVATARS_CONFIG, but it doesn't  
seem to work.

Anyone have any idea how I might get this and other constants I  
require to be available globally?

Thanks

[Rails] Suppressing log messages for an action

[Adam]

Hi all,

I have a rails app that regularly pings the server to check for
changes. The problem I'm having is that my "ping" action is printing
so much output to the log that it's swamping any useful data. Is there
a way to turn off the log for a specific action? Ideally I'd like it
to print to the log only if there's an error, but I'd be quite happy
to just turn off the log altogether for the ping action. I'm using the
default Rails logger.

Many thanks,
Adam

[Rails] Re: "reaper" is not picking up new changes to my application???

[Greg Hauptmann]

Still stuck on this.  I made sure I wasn't in the "current" directory when I
did the call to "reaper" and I still get the same result, i.e. whilst the
process restarts it does not restart with the latest application updates
(made available via the new application being put in a new "releases"
directory, and then capistrano change the sym link for "current" to this new
directory).

Question - Is a "reaper" restart action supposed to update an application?
That is, is the out-of-the box Capistrano command
"/u/apps/equity/current/script/process/reaper" really supposed to update any
changes to an application (via a "cap deploy")?

[Rails] weird behaviour of a Web Service

[Rey9999]

Hello everyone,

I'm currently writing a Rails application which should expose some web
methods, which need to be called by a windows mobile application.
I've been able to successfully call some webmethods from the mobile
application, but only the methods returning simple types as strings,
numbers, arrays etc.

Now I need to expose a method which receives an ActiveRecord object.
In this case, I've witnessed a strange behaviour.
If I write my method this way:

def get_role(role_id)
 a = Role.find(role_id)
 return a
end

I get a "Cannot map Role to SOAP/OM" exception from the mobile
application. Googling this error has lead me to this page:
http://benrobb.com/2007/02/06/cannot-map-objtype-to-soapom/

so I rewrote the method as:

def get_role(role_id)
a = Role.find(role_id)
return Role.new(:description => "#{a.description}", ..[all the
attributes here])
end

but in this case, the mobile application gives me a "FormatException"
error.
I cannot understand why, even if I'm returning a Role object in both
cases, I get two different error messages!
Where or what am I doing wrong?

Thanks in advance!
