You should be able to generate them yourself - run rake doc:guides
from a rails app (it should put the output in doc/guides) or clone the
rails source and run the doc task from there (if you want the most up
to date ones)

Downloading Ruby on Rails guides for offline use?

Hi!

The guides on http://guides.rubyonrails.org/ are masterpieces. Is
there a convenient way to download all of them for off-line use?

Oh yes, it possible to use Postgresql with the BitNami package. But
the downside is that you still end up having MySQL around. :-/
First you install the BitNami Rubystack with MySQL, then you use
Postgresql add-on.

Re: setting response.headers is non-effective?

2009-12-07T06:52:43Z

Both Ruby and C use the == operator to test that the rvalue equals the
lvalue, as in: this_email_message == pedantic

Ruby uses both = and => as assignment operators, depending on the
situation. Of course this prompts the student to ask, are two
assignment operators enough?

Re: Business logic against model records

2009-12-07T06:41:20Z

I had be contemplating a STI solution but it still involved account
types in the database.

I can see a number of problems being solved with your suggestion,
hadn't thought of it this way. My initial thought though is that
potentially there are around 10-15 account types, would this start to
look ugly with so many models extending this single feature?

I've also got to check how STI influences AR performance. Potentially
I've got around a million records in the accounts table as each
product will have multiple accounts based on batches. Each time a
delivery arrives it creates a new batch for that product which in turn
creates a new account(s).

Every product has around 10 accounts, and every product creates a new
set when a new batch of stock arrives, approx. 24 times a year. So you
can see each product may spawn around 240 accounts a year at worst
case scenario. It's a little heavy but storage is cheap and it allows
a fantastic level of visibility of inventory progress and history.
Just got to watch performance. Indexes and caching will likely be
first ports of call.

Once an account reaches zero it is essentially dead and no longer
used, however I need to keep it on hand for audit trail purposes. I
will likely implement an accounting period function which archives
older accounts out of the live accounts table.

view to pdf with pdf::writer

2009-12-07T06:27:44Z

Hello,

I would like to send a view to a pdf file.
To do that I have choosen the tool "pdf::writer", I have tested it and
I found a problem when I do:

pdf.text render :layout => "my_layout"

it sends the whole html code to the pdf file.

How could I send the result of the html file to the pdf file?

Thanks and let me know if you do not understand it.

ArEventComment.ignore_ar_events(:before_create)

or with a block of code:

ArEventComment.ignore_ar_events(:before_create) do

Business logic against model records

2009-12-07T05:49:36Z

Hi,

I have a small architectural decision to make.

I'm modeling double entry accounts to handle product inventory. An
account is a combination of a product, storage location. Accounts also
have sub-types such as "Available" and "Reserved".

Therefore it is possible to have more than one account for the
combination of ProductA and LocationA, one account with type
"Available" and another with type "Reserved". Accounts contain entries
which add or subtract against the account balance. Entries then belong
to transactions which ensure every addition to one account has a
subtraction from another, essentially that product inventory is
preserved.

class InventoryAccount < AR::Base
belongs_to :inventory_account_type
belongs_to :product
belongs_to :storage_location
has_many :inventory_account_entries
end

My issue is with InventoryAccountType, currently this is a AR model
and a simple database table holding around 10 rows with a column for
the type name (Available, Reserved etc). I populate this as seed data
at application setup.

InventoryAccountTypes don't necessarily need to be in the database
although each account will need to be identified as one or the other
some how (currently via foreign key to the types table). They are also
fairly static and may only change with application feature updates.

I now need to define posting rules which are basically business logic
for whenever a particular entry is made to an account of a certain
type. Each account type has it's own set of posting rules.

I have considered creating an AR model for the posting rules and
associating them with the account type. However I'm not sure about
leverage the database layer to hold so much hardcoded business logic
and relationships?

I also don't like relying on seed data to put business logic
relationships in place.

I feel like I should place the business logic and available account
types firmly in ruby code. What do people think? Has anyone tackled
anything similar?

Thanks, Andrew.

Re: Secure receipt generation

2009-12-07T05:15:33Z

Why not just scope the find to the user?

class User
has_many :receipts
end

Then in your controller you can do something like

def show
file_ref = current_user.receipts.find(params[:id])

#Read file code
end

Secure receipt generation

2009-12-07T04:43:44Z

Has anyone got any ideas on how to approach the following:

I generate a pdf receipt and store it in a directory "outside" of
public since I do not want users to be able to just mess about with
URLs and look at other users receipts. However, I do want users to be
able to download and see their own receipt. I am struggling to come
up with a way of the browser showing the pdf but denying access to
other pdf's.

I had thought of using some sort of md5 generated id on a resource
called "receipt" to do a show but in the end there is always some
URL. Is there a way of creating some sort of "one-time-use" URL by
forming the headers accordingly and then simply using a file-read to
serve up the file. To me this seems a bit weird as the whole point of
webservers is doing precisely this.

I must be thinking along the wrong lines.

Thanks.

Could you not just test @posts directly, presumably it will be nil or
empty or something, or am I missing something? I am a bit confused as
I would expect a variable called @posts to be an array of Post objects
but since you are using :id => posts that suggests it is just one.

Re: Why do so many Ruby/Rails developers use Macs?

admin.clients_index 'clients', :controller => 'clients', :action => 'index'
admin.clients_edit 'clients/:id/edit', :controller => 'clients',

Re: Where do I set Custom Headers as default?

Could someone tell me where it is that I specify this?

Assuming that you are on Rails 2.3 or higher, I would use a rack middleware for that. You have an example at http://www.hokstad.com/rewriting-content-types-with-rack.html

Keep in mind that the Rack config file in Rails is replaced by adding the rack middleware to environment.rb instead with:

config.middleware.use NameOfMiddleWareClass

Cucumber and general Ruby question

2009-12-07T01:52:11Z

Hello,

I have this cucumber step definition:

Given /^the site has pages "(.+)" and "(.+)"$/ do | page_1, page_2 |
    Page.create :title => page_1 if Page.find_by_title(page_1).nil?
    Page.create :title => page_2 if Page.find_by_title(page_2).nil?
end

This works, but obviously I would like to DRY it up. I was thinking along the lines.

Given /^the site has pages "(.+)" and "(.+)"$/ do | *args |
    args.each { |page| Page.create :title => page if Page.find_by_title(page).nil? }
end

The code is not syntactically correct that is what my question is about: how to implement this concept right?

Thanks.

Re: Problem installing RoR Ubuntu 9.04

2009-12-07T01:34:32Z

Hi, Luiz!

I had the same problem as you. Namely, I struggled with installing RoR
development environment on my Ubuntu box.
I found a nice and EASY solution: use BitNami RubyStack, which is
available at http://bitnami.org/stack/rubystack. Everything
is included, and it works out of the box. I highly recommend it.

It has a very clear user guide as well, at
http://bitnami.org/files/stacks/rubystack/2.0-0/rubystack.pdf.

HTH.

Ubuntu + RoR + Firebird OR Ubuntu + RoR + PostgreSQL ?

2009-12-07T01:34:29Z

Dear friends,
I am starting to build a system for an university using RoR. I would
like to use Firebird because I worked with it for a long time and I
love it! In this new project I will use a lot of stored procedures,
data referential integrity and so on. But when I looked for the
Firebird adapter for Ruby and the activerecord for Firebird adapter,
it seems to have so few support and so few users, that I am afraid
about its future.
This is one of the most important e-mails I've sent on my life....! If
I have to start using Postgre the time is now. But with a great pain
on my heart for the Firebird.
Could someone give me a good advice?
Thank you very much!

Re: Problem installing RoR Ubuntu 9.04

2009-12-07T01:22:05Z

Usually when you export the path it should work. Check again that the
path corresponds to the gems path where you have the Rails gem. You
can use this command:

gem env

to gather more info about the gem environment and you should be able
to see the GEM_PATH, so check if in that path you have the Rails gem.
It is a boring problem but it is usually a path issue.

Have you installed another version of Ruby? Reply with you gem env
output to get more help.

Tim, the most recent version of hpricot is 0.8.2. Thus, if you're reinstalling

things, you might want to begin by making gemcutter.org your primary gem

repository by doing the following:

sudo gem install gemcutter

gem tumble

sudo gem install hpricot

Next, let's poke around your environment a bit by executing the following

commands:

which gem

gem environment

which ruby

Please give that a try and report back.

Good luck,

Re: Problem installing RoR Ubuntu 9.04

OK but... I forgot to ask... before any try to solve my problem, I
think I have to uninstall RoR and then reinstall. How to do that? I
found something but as I'm a novice, it's difficult to choose a path.
Thank you for all that gently replied!

Because this is Ruby, not C?

Re: setting response.headers is non-effective?

2009-12-06T22:13:39Z

your way is correct.

http://guides.rubyonrails.org/action_controller_overview.html#other-ways-to-use-filters

9.2.1 Setting Custom Headers

If you want to set custom headers for a response then response.headers is the place to do it. The headers attribute is a hash which maps header names to their values, and Rails will set some of them automatically. If you want to add or change a header, just assign it to response.headers this way:


response.headers["Content-Type"] = "application/pdf"

2009/12/7 CoolAJ86 <coolaj86@...>

As far as I know, this should append these headers to the response
from Rails no matter what, right?

I've checked in Fierbug in Fierfox 3.5.5 and I only see my usual
headers. What might be getting in the way?

#app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
after_filter :cors

def cors
response.headers['Access-Control-Allow-Origin'] == '*'
response.headers['Access-Control-Allow-Methods'] == 'POST, GET,
PUT, DELETE, OPTIONS, HEAD'
response.headers['Access-Control-Allow-Credentials'] == 'true'
response.headers['Access-Control-Allow-Headers'] == 'X-
PINGOTHER'
response.headers['Access-Control-Max-Age'] == '86400' # 24 hours
end
end

Re: how do I manually create POST parameters that are nested? (e.g. I'm creating the request in .Net to contact a Rails backend)

2009-12-06T21:54:58Z

got it - it was actually as simple as creating the name for the key/value pairs in .net client to look like: "webfile[path]" :)

2009/12/7 Greg Hauptmann <greg.hauptmann.ruby@...>

Hi,

How do I manually create nested POST parameters for a http web request? I have a .NET C# client for which I'm creating a HTTP request to a Rails page. Everything is fine so far, however I've noted that the parameters I'm creating for the request (key/value pairs) are expected to be nested. I'm actually also having a hard time trying to work out in a controller before_filter how to do a "puts" on the raw request content to see how a successful request formats it.

RAILS BACKEND EXPECTATION (a successful login file, when I called from browser (not .net))
action_controller.request.request_parameters: !map:HashWithIndifferentAccess
commit: Save
webfile: !map:HashWithIndifferentAccess
path: winter
file: &id005 !ruby/object:File
content_type: image/jpeg
original_path: Winter.jpg

C# Parameter Creation:
            var form = new NameValueCollection();
            form["path"] = "winter"; ==> THIS DOESN'T WORK BECAUSE I THINK IT MAY HAVE TO BE NESTED WITHIN THE "webfile" HASH

C# Routine:

        public static HttpWebResponse Upload(HttpWebRequest req, UploadFile[] files, NameValueCollection form)
        {
            List<MimePart> mimeParts = new List<MimePart>();

            try
            {
                foreach (string key in form.AllKeys)
                {
                    StringMimePart part = new StringMimePart();

                    part.Headers["Content-Disposition"] = "form-data; name=\"" + key + "\"";
                    part.StringData = form[key];

                    mimeParts.Add(part);
                }

                int nameIndex = 0;

                foreach (UploadFile file in files)
                {
                    StreamMimePart part = new StreamMimePart();

                    if (string.IsNullOrEmpty(file.FieldName))
                        file.FieldName = "file" + nameIndex++;

                    part.Headers["Content-Disposition"] = "form-data; name=\"" + file.FieldName + "\"; filename=\"" + file.FileName + "\"";
                    part.Headers["Content-Type"] = file.ContentType;

                    part.SetStream(file.Data);

                    mimeParts.Add(part);
                }

                string boundary = "----------" + DateTime.Now.Ticks.ToString("x");

                req.ContentType = "multipart/form-data; boundary=" + boundary;
                req.Method = "POST";

                long contentLength = 0;

                byte[] _footer = Encoding.UTF8.GetBytes("--" + boundary + "--\r\n");

                foreach (MimePart part in mimeParts)
                {
                    contentLength += part.GenerateHeaderFooterData(boundary);
                }

                req.ContentLength = contentLength + _footer.Length;

                byte[] buffer = new byte[8192];
                byte[] afterFile = Encoding.UTF8.GetBytes("\r\n");
                int read;

                using (Stream s = req.GetRequestStream())
                {
                    foreach (MimePart part in mimeParts)
                    {
                        s.Write(part.Header, 0, part.Header.Length);

                        while ((read = part.Data.Read(buffer, 0, buffer.Length)) > 0)
                            s.Write(buffer, 0, read);

                        part.Data.Dispose();

                        s.Write(afterFile, 0, afterFile.Length);
                    }

                    s.Write(_footer, 0, _footer.Length);
                }

                return (HttpWebResponse)req.GetResponse();
            }
            catch
            {
                foreach (MimePart part in mimeParts)
                    if (part.Data != null)
