[Rails] Rails 3.2.6 hates dbi gem ?

[Satish S.]

I have a  bad problem

I have a small rails app .. was running fine with ruby 1.8x and rails
2.x
In my extreme stupidity I decided to move to ruby 1.9.x and rails 3 ..
and it's a glorious pain.

My ruby app uses mysql .. and I use active record for that.
However there is an earlier pgm I had written to fill in the database
before I did rails (2x) which is part of the complete  application now.
( I can test/run the standalone pgm outside rails and there is no
problem .. it works)

This standalone program in using mysql and dbi gems
  I call this program as such from a model

 system("ruby standalonepgm.ruby -args ")

In  rails 2.0 this  worked without any issue.
In 3.0 the program exits without any way to capture the error.


Running under console I see that the program dies because it can't find
dbi gem!

If I put dbi gem in the Gemfile and do bundle date  but then there is
real trouble.
Rails refuse to start  -  "rails server" dies with all kind of issues ..
I can put in the screendump ..
but that's unimportant  I think.

There seem to be 2 issues
1. DBI is surely incompatible with the  gods of rails
2. Rails creates a sandbox .. and all programs called must live in that
sandbox (that's why just a require statement doesn't suffice).

My question is .. is it fixable or I am one of those who got bitten by
the hidden black magic of rails .. and my past 8+ weeks of effort is
down the tubes  ?

[Rails] Re: formats in action view base

[John Merlino]

Let's say I call LookupContext with a details hash consisitng of a
format. Here's the sequence as I understand it:

1) First lookup_context.rb is loaded, which means the macros are
called immediately. The register_detail macro, accepts a symbol and
block. We pass it a symbol :formats and a block whose return value is
an array of symbols representing a variety of formats:

    register_detail(:formats) { ActionView::Base.default_formats ||
[:html, :text, :js, :css,  :xml, :json] }

2) We declare a getter/setter registered_details at module level
(which will make it available at class and module level (e.g.
LookupContext.registered_details or Accessors.class.registered_details
- where class refers to Module)). We initialize it as an array in
LookupContext class context. When register_detail class method is
invoked, we append the :formats symbol to that array. We overwrite the
assignment of initialize by iterating through that class array and
indexing strings that we will later evaluate. The strings substitute n
for :formats. In other words, when the string is evaluated in ruby, it
will check if a user passed a :formats key in the details hash passed
to the initialize method, and if not, then it will default to the
implementation of default_formats. Then the result is assigned to the
@details instance variable hash. That default implementation is
defined using :define_method and sending the message to the Accessors
module, which is included in LookupContext, and, thus, default_formats
is available to LookupContext objects as public instance methods. We
declare a setter/getter formats method via the Accessors module. And
then we declare an initialize_details method, which will be evaluated
when the constructor is invoked during the instantiation of
LookupContext. At this point, we just did some dynamic definitions via
declarative macro-level class methods.

    mattr_accessor :registered_details
    self.registered_details = []

    def self.register_detail(name, options = {}, &block)
      self.registered_details << name
      initialize = registered_details.map { |n| "@details[:#{n}] =
details[:#{n}] || default_#{n}" }

      Accessors.send :define_method, :"default_#{name}", &block
      Accessors.module_eval <<-METHOD, __FILE__, __LINE__ + 1
        def #{name}
          @details.fetch(:#{name}, [])
        end

        def #{name}=(value)
          value = value.present? ? Array(value) : default_#{name}
          _set_detail(:#{name}, value) if value != @details[:#{name}]
        end

        remove_possible_method :initialize_details
        def initialize_details(details)
          #{initialize.join("\n")}
        end
      METHOD
    end

    include Accessors


3) Now that our LookupContext class has a template we can use, we
instantiate a LookupContext object, passing in a hash with a formats
key:

    LookupContext.new('app/views', {:formats => :abc})


4) The constructor method is called. We pass in our hash as a local
variable called details. We initialize our LookupContext @details
instance variable to be an empty hash. Hence, now we have a @details
instance variable available to the instance methods of the
LookupContext object instances. We then call initialize_details
method, passing in our details hash, which comprises of the hash we
passed as the second argument during initialization of the object.
Remember our initialize local variable is an array of strings. In this
case, it's an array of three strings, since we call register_detail
three times, passing each time a symbol and block. Now the array of
strings get evaluated and we add a nonbreaking space so the ruby
interpreter doesn't raise any kind of syntax exception during the
evaluation. We check if the details parameter contains a :formats key
and in our case, since we passed a :formats hash to the constructor it
does, so we assign the return value (:abc) to the :formats key of the
instance variable @details hash. Note if we did not pass an argument
to the constructor, then default_formats would be invoked, and
remember we used define_method on Accessors module to build the
defaults_formats method and assign it a default block, which returns
an array of defaults for formats. So now we have our @details instance
variable that we initialized with the constructor, we then assigned it
a key/value pair value (e.g. :formats => :abc). So by invoking the
getter formats method we dynamically created, @details.fetch(:formats)
will return :abc.


    class LookupContext
    def initialize(view_paths, details = {}, prefixes = [])
      @details, @details_key = {}, nil
      @skip_default_locale = false
      @cache = true
      @prefixes = prefixes
      @rendered_format = nil

      self.view_paths = view_paths
      initialize_details(details)
    end


5) Then we decide to set a format, for example, when we instantiate
ActionView::Base, passing a format as the fourth parameter to it:

    lookup_context.formats  = formats if formats

[Rails] formats in action view base

[John Merlino]

When you invoke ActionView::Base, it in turn invokes a LookupContext
object. The LookupContext class object has some class level macros
that builds some instance methods corresponding to a format:




register_detail(:formats) { ActionView::Base.default_formats ||
[:html, :text, :js, :css,  :xml, :json] }
 def self.register_detail(name, options = {}, &block)
  self.registered_details << name
  initialize = registered_details.map { |n| "@details[:#{n}] =
details[:#{n}] || default_#{n}" }

  Accessors.send :define_method, :"default_#{name}", &block
  Accessors.module_eval <<-METHOD, __FILE__, __LINE__ + 1
def #{name}
  @details.fetch(:#{name}, [])
end

def #{name}=(value)
  value = value.present? ? Array(value) : default_#{name}
  _set_detail(:#{name}, value) if value != @details[:#{name}]
end

remove_possible_method :initialize_details
def initialize_details(details)
  #{initialize.join("\n")}
end
  METHOD
end


So these methods are included as instance methods via the Accessors
module. Later the LookupContext class override the formats method with
its own definition:

def formats=(values)
  if values
values.concat(default_formats) if values.delete "*/*"
if values == [:js]
  values << :html
  @html_fallback_for_js = true
end
  end
  super(values)
end

1) So what was the purpose of adding a formats method to the Accessors
module and then include it into LookupContext, if it will always be
overriden by LookupContext's own implementation?

2) What is meant by expand ["*/*"] values in the comment "# Override
formats= to expand ["*/*"] values " which is directly above the
formats implementation on LookupContext?

Re: [Rails] [RSpec Testing] Methods take two arguments

[Mirri Kim]

P.S. But still, this will probably fail because you're not actually doing
anything (at least that's obvious) to trigger PdfHelper.create_pdf. "user"
has no knowledge of "file" assuming you have a callback to create a pdf
when a user is created. The first test is also weird, it's like saying a =
1; a.should == 1.

No one is going to be able to even confirm your suspicions without

What "texts"? What "examples"? What versions of Rails, gem, etc.
are you trying to use? What problems are you having? Saying that

Try this:

@users = User.where("id NOT IN (?)", @issues.map(&:id))

Are you using Rails 2.3 or 3 or 3+? I think the find(:all) is deprecated after 
2.3.

[Rails] ROR books seem to be out of date

[brian brian]

i am trying to get started on ROR but the texts all seem to be out of date 
as regards samples that wont run on later IDEs such as aptana studio 
,rubymine and so on.github examples are also out of date and wont run.
beginning Rails3 samples appear to also not able to run ,even using github 
examples .
ruby on rails for dummies is unusable as the IDE radrails is a later 
version without the helpfull tabs , also the less is more interface on 
aptana studio makes it difficult.
the only progress i can make is using the command line but again samples 
wont run when i use them from the ROR books .
i suspect the problem is later versions of the rails and gems s/w.

Re: [Rails] Array value to get except first two values

[Yong Gu]

If you are using Rails, 

%w( a b c d ).from(0)  # => %w( a b c d )
%w( a b c d ).from(2)  # => %w( c d )
%w( a b c d ).from(10) # => %w()
%w().from(0)   # => %w()

[Rails] Re: New to Ruby

[fuzzy]

Hello Samir,

I am a newbie as well, and not even a programmer ... I have built up
this list of potential help. Some are free and others you pay for.
Just check each one out and use there free services until you get more
proficient.

I used Michael Hartl' screencasts to learn the basics. Here is the
url:
http://ruby.railstutorial.org/ruby-on-rails-tutorial-book

There is many other tutorials, Rob Connery has some introductory
screen casts:
http://tekpub.com/

Ryan Bates has a whole lot of railscasts that address specific issues
in rails:
http://railscasts.com/?view=list

Kevin Wang and Chris Lee are offering a course in rails:
http://www.railstutors.com/

Then you have railsmentors.org where you can sign up and request a
mentor to help you through a sticky spot.

Another great resource is Rails Guide.

Peepcode has a series on rails:
http://www.rubyinside.com/peepcode-releases-the-meet-rails-3-screencast-series-4039.html

Rails Zombies is a fun introduction:
http://railsforzombies.org/

Another great service is Rails hotline ... this one you phone up and
you get a rails programmer on the phone who will talk you through your
problem ... if you find he has really helped you, then you can buy the
group some more phone minutes ... this is all explained at the web
site:
http://rails.pockethotline.com/

Another site, just for reference, is a real expensive site but for
folks who are already proficient in rails but want some more power ...
owningrails:
http://owningrails.com/

I guess that is it for me ... I think there are even more resources
but maybe some of the other members could fill you in on those.

Keep on riding the rails.

Re: [Rails] (JOB) Looking for RoR Engineer

[Panayotis Matsinopoulos]

@Gintautas I agree with you that all the details of a job posting should be
there from the beginning. But, please, exactly as you say that "this
mailing list is not a place to defend claims about Greece being a step from
bankrupt"
you need to know that *this mailing list is not for you to tell anybody
that Greece is a step from bankrupt in the first place. NO IT IS NOT A
FACT* that
has to do anything with this list.
*
*
Is that clear?

I believe that we need to start talking seriously here. Ask for job
postings to be fully detailed - and I am all with you, but stop telling
whether Greece is a step before or after anything. It is the person who
will read the post that will make his
own research/search about it.

Re: [Rails] How to read Microsoft document file in ruby on rails ?

[Paul]

The docx format is actually pretty simple: it is a zipped set of
files. If you upload it to the server and unzip it, you'll see a set
of xml files. You can poke around and figure out the format, or you
can find a spec on line.

Re: [Rails] (JOB) Looking for RoR Engineer

[Gintautas Šimkus]

Well if a country requests billions in euros of help, it indicates that
they are not 'well' nation wide. I meant that the country of work is
important and should be mentioned in a job proposal. That's it.

Yeah I must've missed the joke on this one. It looked like a Greek tried to
defend the proposition that working next to a sea is more important than
the longer term guarantees for an applicant.

If you take the fact that Greece is a step from bankrupt, then this mailing
list is not a place to defend such claim. Just let people know and they'll
decide by themselves.

No problem. I deduce you are Greek. And that you tried to advocate working

I mean people should decide by themselves where to work. And working in

Re: [Rails] (JOB) Looking for RoR Engineer

[Gintautas Šimkus]

No problem. I deduce you are Greek. And that you tried to advocate working
in Greece is similar to working in DE or US, which is not that case at this
point.

I mean people should decide by themselves where to work. And working in
Greece (or any other country) is OK with me. I was just pointing out that
the same job proposal could be crap under certain circumstances.

I am simply for telling people where they'd be working for right off. You
tried to defend Greece as a viable option. It might be, I don't know, but
relocating there would pose serious questions for an informed applicant.

You know where there is high risk, there is also an opportunity. So Greece
is OK, again, in my book, but letting people know whether they'd be working
in Beirut or NY could be a page turner for most.

P.S. I am working for a Greek company that has 200% sales growth every year

If reinstalling the gems in a clean gemset doesn't work then It's usually 
an environmental thing, for example if you use macports its sometimes 
possible for one version of a library to be picked up while compiling ruby 
(or a gem) but a different version is used when ruby actually runs. 
Unfortunately working out exactly what is wrong is a bit hit and miss

Not sure if you aware of it or not but Greece has a high chance of going
bankrupt. So that maybe where the concerns come from. Blue sea is nice when
you can live in the country w/o a good chance for your company to be
nationalized, drop in value, or start paying you in some bogus currency
which they've been printing 24/7 for 3 months (= little real value).

Re: [Rails] Re: "belongs_to" aliases

[Panayotis Matsinopoulos]

You may be right, but I have found a lot of other posts on Internet that
they complain about "belongs_to". It does not bear the correct meaning for
all cases. For example:

class Product

belongs_to :status

end

.Awful. No, the Product does not "belong" to a Status. It "has_a"
status.

Also, "belongs" usually means that a "composition" relationship, such that
if Status were to be removed, the corresponding Product would have to be
removed too.

Another example:

class Product

belongs_to :type

end

Awful again. The product Types preexist the Products and a Product does
not belong to a type. "is of" a type.

Certainly, the "belongs_to" as a DSL does not describe the domain on the
particular cases.

Thanks for letting me know that my workaround will work. I will have the
second thoughts on whether to use or not. I have read the article by Dave.
Thanks for that reference too.

Peter ... you are absolutely right.

BTW1, Greece is very-very-very cheap and has fantastic weather and
beautiful sea and beaches.
:-)

BTW2. I am certain that this job cannot come from a Greek company. Greek
companies rarely use Ruby on Rails. Most of them use java technologies and
.NET

Can any body please help me to solve this?

be a set of number from 0 to n random number every time. 
If the given number matches the random array[0] number by the program, show 
a message you won the loterry.
If the given number matches the random array[1] number by the program, show 
a message you are second.
