Re: [Rails] rubyzip install error

2010-12-21 Thread Dhruva Sagar

Hi,

May I ask you why you are not installing the rubyzip gem directly from
rubygems as it suggests ?
Is there a specific reason why you are trying to install from source ? If
not, then I would suggest you to take the approach recommended by the gem
itself, and install it from rubygems using a command like gem install
rubyzip. If for some reason you wish to install the latest from source, I
would suggest you to contact the developer or check the source directly...

 You use grails too?
 I'd like to have some opinions about grails and RoR.
 I use both, but lately I prefer grails to develop my applications.
 With RoR you have to think about tables, create foreign key, and so
 on, with you have to create your domain classes and that's all.

Yes, I do use Grails as well, and at this precise moment I am working
on a project that required me to use it.

Before jumping into Rails as my primary development framework, I used
to use mainly Grails, and J2EE before that. Groovy is so much like
Java that I just picked it quickly. I also learned Ruby quickly as it
is pretty similar in syntax to Python, which I have and still use it
quite a lot for System Administration.

I think both frameworks are pretty similar and pretty good, and Grails
has the advantage of allowing you to make use of existing Java
frameworks and tons of libraries available. Specially when you need a
reporting solution or support for a certain RDBMS, which does not
happen with Active Record. I haven't really tried DataMapper or
another ORM framework.

I often decide on what framework to use based on the target platform,
RDBMS and reporting solution. For instance, if the target platform is
Windows, there is no doubt that I will use Grails, since Rails is not
very Windows friendly. If I don't need any special RDBMS, advanced
reporting capabilities, or Windows, then I go for Rails. In fact I
only develop with Grails on the Windows platform. Other than that, I
use Rails.

In the beginning I used Rails only for websites, but now we are using
it even for developing financial and accounting software.

Now with regards to thinking in tables terms, I prefer it over letting
a framework do everything for me. Contrary to what many people can
say, Object-Oriented programming and the Relational model are
compatible to a certain extent. There are certain OO concepts that are
hard to implement in a Relational model. Take inheritance for
instance. How many approaches do you have for that? They all have
their pros and cons, but none is a perfect match for the real concept.
So, to a certain degree you need to think in terms of tables or use an
ORDBMS, which is easier to map.

The relational model is here to stay for a very long time.

All the best,

Fidel.

Rails is always my first choice when I begin a new project. I only
resort to Grails when I face situations that require me to use it.
Such as the ones I have described in my previous post. As for Windows,
I only use it if it is one of the client's requirements. Otherwise, a
use a Unix-based system.

 I develop only web applications for now, I'm using both grails and
 rails with jruby because I prefer to deploy under a servlet container
 like tomcat.
 I love both, I cannot decide which one prefer.

I also don't have a favourite framework, but I do favour Ruby over
Groovy, and that is what leads me to go for Rails. I think that either
framework can do the job, and in the end it comes down to language
preference, at least for me.

Fidel.

[Rails] associations / json and doing things right

2010-12-21 Thread bingo bob

I'm doing stuff with Apps in the App Store. Apps belong to a price tier.
Such that.

App
  belongs_to :tier

Tier
  has_many :apps

All good so far.

I want to monitor when an app changes tier amongst other thing, don't
need a history, but need to record the previous tier.

My plan was to store attributes on the App for tier_code and
previous_tier_code, but this strikes me as wrong because an App belongs
to a Tier at a point in time so I don't need to store the tier code
twice (and I shouldn't).

The main reason I've stuck the tier_code attribute on the App is I wish
to serve up JSON from the AppController's index action. With all the
attributes I need on the App directly I can just format.json { render
:json = @apps } or the like.

What could/should I do, ideally I'd like to remove the tier_code
attribute on the App, and incorporate it in the json via the association
- looked into this and it made my head spin.

They're almost completely unrelated. attr_accessor is part of ruby
itself and is equivalent to calling attr_writer and attr_reader for
the same argument(s), ie it creates accessor methods for you

attr_accessible is a rails thing and is part of rails' mass assignment
protection (along with attr_protected). It allows you to setup a
whitelist of attributes that can be mass-assigned (as opposed to
attr_protected, which sets up a blacklist) so that users can't set
important attributes they're not supposed to be able to set just by
manipulating the form data that is posted

[Rails] Problem with validates uniqueness and accented characters

2010-12-21 Thread Victor Cisneiros

I have a table 'client' with a unique index on column 'nome'
I have also set validates :uniqueness = true on column 'nome'

There is a record 'João Victor Santos' on my clients table. When I try
to insert another 'João Victor Santos' Rails executes the following
command to check if a record with this name already exists:

SELECT `clients`.`id` FROM `clients` WHERE (`clients`.`nome` = BINARY
'JoÃ£o Victor Santos') LIMIT 1

Unfortunately this query returns 0 rows and validation passes and I
receive this stack trace

Mysql::Error: Duplicate entry 'João Victor Santos' for key 2

If I execute this query in phpMyAdmin it correctly returns 1 result

SELECT `clients`.`id` FROM `clients` WHERE (`clients`.`nome` = 'João
Victor Santos') LIMIT 1

I'm using Rails 3.0.3, Ruby 1.8.7 and the mysql gem. I can't switch to
mysql2 gem because I'm running on Windows and this application will also
run on Windows in production

Has anyone faced this problem?
