[Rails] Re: find a string in a file

[AGoofin]

Should be able to do something like to separate the tasks:

u = open( "myfile" )
  while line = u.gets
if line.include?( "taske :" )
  anArray = line.split(' ')
  puts anArray[1] if anArray.length > 0
end
  end

You could even combine the split function with the index function
line,split(' ')[1] if you are sure where the target info will be.

Note: Don't be afraid to try different things. This solution is only
one of many and others here could do a lot better. You could do better
with a little practice and research.

However, your code will be much more testable if you do the filtering
on @notes in the controller, or even better, by writing a method in
your model that only returns records with type of class String.

[Rails] Filters

[Fernando Aureliano]

Hi,

How I do a filter in a block of code?

example:

I have a block:

<% @notes[(0..3)].each do |note| %>
  
<%= notes.note %>
<%= notes.type %>
  
<% end %>

Type is a string, I would like to do a block filtering by a value on type.




Thanks!

I've been using it ever since reading dire warnings in the first
edition of Agile Web Development with Rails:

"[To represent true or false, some databases] use integer columns,
where 0 is false and 1 is true... The problem is that in Ruby the
number 0 and the string "f" are both interpreted as true values in
conditions... To query a column as a boolean value in a condition, you
must append a question mark to the column's name"

I must confess I was surprised to learn (prompted by this thread) that
Active Record has a feature that emulates boolean columns for
databases that don't support them natively, so you do get a literal
true or false value out of the attribute, instead of a 1 or 0. And was
even more surprised to learn that this feature was added quite a long
time ago (version 1-ish, AFAICT).

But warnings like the above are still passed on (and in fact are still
present in the current edition of AWDWR). I and others clearly missed
the memo.

> Is that syntax documented somewhere?

It's currently implemented in ActiveRecord::AttributeMethods::Query,
and mentioned in the preamble doc for ActiveRecord::Base (but only as
a way of checking for the presence of attributes, not as a way to
typecast fake boolean columns).

The MySQL connection adaptor's boolean emulation behaviour is
configurable via
ActiveRecord::ConnectionAdapters::MysqlAdapter.emulate_booleans, which
is documented.

[Rails] Re: Different user sessions with different domain name?

[tashfeen.ekram]

This has been great advice. I am using nginx. (I know this is now not
a rails questions, but I figured to complete the post here so as not
to cross post). The way to to do this on nginx is as follows:

server {
  listen  80;
  server_name domain.com *.domain.com;
  rewrite ^   http://www.domain.com$request_uri? permanent;
 }

server {
  listen  80;
  server_name www.domain.com;

  index   index.html;
  root/home/domain.com
}

Re: [Rails] Power Point / Keynote presentation in website

[Chad Eubanks]

Hi,

I actually use keynote to prototype all my applications with the exception of 
mobile apps.  I use dashboard for mobile apps.  The front end technology my 
team uses is SproutCore and the animation framework is awesome.  

SproutCore provides good cross browser support and would highly recommend it.  
Check out the following demos and git account for sample code:

animate.strobeapp.com
animatedemo.strobeapp.com
http://guidesdev.sproutcore.com/animate.html
github.com/thecodeboutique

Furthermore, we will be releasing training material for SproutCore on the front 
end and rails on the backend shortly at sproutcoreonrails.com.  I will keep the 
community up to date when I can provide more information.

Kind Regards,
Chad Eubanks
The Code Boutique

Re: [Rails] Power Point / Keynote presentation in website

[Peter De Berdt]

Most of the effects can either be achieved with CSS3 (animations) or  
Javascript, Rails is all about the serverside, these kinds of  
animations are clientside and thus need clientside scripting. Keep in  
mind that CSS3 animation support is very limited at this time in most  
of the current browsers (Safari seems to be way ahead of everyone else  
on the animation front). Also, it's not going to be a trivial task to  
achieve that kind of animation.


For what it's worth, I myself and quite a few people I know (even non- 
developers) hate this kind of site where you have to wait for about 15  
seconds before the actual content appears. It doesn't add anything  
useful to the site itself, except for a delay in getting to the  
information you want. Animation should be an added value, not a means  
of being fancy and dandy.


However, looking back at your original question (and the title of this  
thread), you are looking for Powerpoint/Keynote-like transitions. As I  
originally responded, both of these can be achieved with CSS3 (most  
performant on mobile devices) or Javascript (works cross-browser).

That is not really a Rails question, but the effect is done using
Flash.  Please don't do it, it is horrible to have a site that relies

Re: [Rails] ActiveRecord array/collection manage

[Valery Kvon]

Pagination obviously doesn't works on Array, but ActiveRecord::Relation set.

You have to rewrite your color selector using 'standard de facto' approach:

class Car < ActiveRecord::Base
  scope :colored, lambda { |color| where(:color => color) }
end

Then just call:

Car.colored(%w{red blue}).page ... etc

Install either
  rails-footnotes  -- http://rubygems.org/gems/rails-footnotes
or
  new relic rpm -- http://newrelic.com/

to collect real data on where the time is being taken. It could be DB,
it could be rendering, it could be a combination of things.

[Rails] RoR/Ruby slowness

[Tom Meinlschmidt]

Hi all,

still fighting with incredible ruby slowness with RoR development. Not only 
tests, but whole development takes
a lot of time, getting eg. 2000ms to complete page render (with mysql5). Trying 
various versions of ruby (1.8.7, 1.9.1, 1.9.2), but
still the same. Using mbp late 2009, 4gb ram, osx 10.6.7 

anyone experiencing the same?

That is not really a Rails question, but the effect is done using
Flash.  Please don't do it, it is horrible to have a site that relies
on flash.  Think of those with limited bandwidth.  Also it will not

[Rails] ActiveRecord array/collection manage

[danimashu]

Hello, I have a model like this:

class Car < ActiveRecord::Base
  def color(c)
where("color = ?",c)
  end
end

Suppose that I want to show the red and blue cars. I could do
something like this:
@cars = Car.color('blue') + Car.color('red')

The problem I'm finding is that now, @cars is an array and I could not
do something like that:
@cars.page(params[:page]).per(10)
@cars.order( . )
or any method ActiveRecord implements. The question is: ¿How can I
manage ActiveRecord array/collection for do: + - | &?

Thanks very much.

[Rails] Re: Cancan redirect back at AccessDenied

[koulikoff]

If your request does not have the HTTP_REFERER defined,
redirect_to :back does not know where to redirect.
Ususally in this case root_url is used.
I hope, it will not be too difficult for you to combine

[Rails] Cancan redirect back at AccessDenied

[Yiannis]

Hello

I have a rails 3 app and I am trying to implement the redirect back
action at access denied for cancan.

If I try this in my application_controller:
  rescue_from CanCan::AccessDenied do |exception|
redirect_to :back
  end

It gives the following error:
No HTTP_REFERER was set in the request to this action, so
redirect_to :back could not be called successfully. If this is a test,
make sure to specify request.env["HTTP_REFERER"].


I can't really understand why there is no http_referer, how is back
button working on views? Is it possible to implement a general back
action for the cancan access denied exception?


I like the devise approach of "back" method after sign in:
def after_sign_in_path_for(resource)
stored_location_for(resource)
end

It would be perfect if I could combine them.


Thank you!

Re: [Rails] Built in (boolean)? method

[Chris Kottom]

Sorry, I misunderstood the original message.  Ran similar tests in my local
environment with same Ruby / Rails, and wasn't able to get a similar
outcome.  Is there anything in your model that could be overriding the
dynamically created accessor?

It works ok for me using mysql, could you post the section of
schema.rb for that table?

I have never used the for_charity? syntax though.  There does not seem
much point when it is a boolean.  Is that syntax documented somewhere?

Re: [Rails] Built in (boolean)? method

[Ants Pants]

i know about the storage issue (or at least I thought I did) but what I am
saying is that the returned values are different between the attribute
for_charity and for_charity?

Surely that has nothing to do with how the values are stored? I sent the
output form console in my original email to show that.

The result of Model.where( some_condition ), for example, is an
ActiveRecord::Relation object rather than an array.  You can for
example apply further .where operations on it to refine the search
further.
