Basically, this gives me a list of 500 random decimal numbers that are
rounded to 3 places. However, I also want to make sure that all are
unique.
This is a classic how do I achieve my solution?, rather than a
here's my problem... how can I solve it post...
Can we back up a second please?
What are you trying to achieve with this list of 500 numbers? And what
do you want to do if the list you have generated does contain
duplicates?
As already said, you can use the .uniq method to remove dupes - but
that might leave you with an array of 496 elements... would that be a
problem? Are you really asking how do I generate an array of 500
random numbers?
What do you want to do with these 500 random numbers? Considering that
one user could make a request and get their 500 randoms, and another
user could do the same - there could be duplicates across users. Is
this going to be a problem?
Please try to ask clearer questions, as the way it stands, I could
spend ages of my time coming up with solutions to what I *think* is
your problem, just to have you say nope... that's not what I was
after. Multiply that across the subscribers to this list, and you've
wasted a hell of a lot of peoples' time around the world :-/
PS BTW Why are you multiplying by 1 in your example code? (and does
that line even work if you paste it into your console, as it explodes
for me with a LocalJumpError... but that may just be Ruby versions...)

The more numbers you ask this to generate the more rounds it will take to produce the result. Generating 500 unique numbers is averaging about 700 rounds. The closer to 1000 you get the more rounds it will take. Over 1000 and it will never finish. Another caveat is that the Array contains Float objects, while the original question was 500 unique decimals. Two issues here: 1) if decimals are asked in the problem statement, why then do we serve Floats in the result? 2) The problem is that for uniqueness, we need the '==' operator and on Floats that represent fractional numbers in the decimal system, equality is not a stable function (as was discussed many times before ...). So, in all proposed solutions, I would exchange this line: value = Integer((rand * 1) * 1000) / Float(1000) with this one: value = rand(1000) / BigDecimal.new(1000) HTH, Peter -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Therefore there is the error that the method 'current' is not defined for the number 6. Now if your question is 'why is @book_pages the number 6' then you must look at the code where you setup @book_pages. I think you would be better to work through some tutorials first however. I suggest that you forget what you are doing for a few days and work right through something like railstutorial.org, which is free to use online.

[Rails] Deploying to a DMZ

If I understand correctly, the root problem of the OP is not being able to use standard capistrano recipes since the production server (in the DMZ) cannot reach the git repo that is inside the company firewall? What I have done in such a scenario (where my production server is at a hosting company) is to use standard capistrano practice, but have a production branch of the git repo on the production server. So the `git checkout` on the production server is pulling from a local repo. The top of my deploy.rb then becomes something like: set :user, 'vandenabeele' # username on the production server set :application, 'flamjobs' # app name set :repository, 'vandenabe...@xxx.yyy.zz:git/flamjobs.git' set :branch, 'production' For that, I has set-up a bare repository in the directory /home/vandenabeele/git/flamjobs.git and I push into that from my dev machine before running cap deploy (I could probably automate that too ...).

[Rails] Passing params to :delete
Hi, I'm new to Rails, and I'd like to be able to redirect from methods in my Controller, based on the page I've come from. I know I can do: %= link_to 'Show', event_path(@event, :from = 'page1') % and :from will be passed to params, and I can redirect based on this on my Controller. I have a few quesetions. Firstly, is this a good idea? Is there a better way of doing it? Secondly, how can I achieve this with the :delete method? It uses slightly different syntax, as far as I'm aware. %= link_to 'Delete', @event, :method = :delete % Thirdly, how can I achieve this with the edit action? My edit currently looks like this: def edit @event = Event.find(params[:id]) end And it renders a form, which I assume goes to the update action. So how can I get the param[:form] from 'edit' through the form into 'update'?

I think my suggestion was better. If you can put something in the
model it is generally better than in a helper.
But to use Walter's method, did you change the code in the view to use
the helper method?

IF you created the helper method I posted earlier, you would want to replace
your entire image tag code in your index.html with
%= avatar(user) %
But I like Colin's idea even better, since it separates concerns more neatly.
#models/user.rb
...
def user_photo
(photo.url?) ? photo.url : 'default.png'
end
And then in index.html.erb:
%= image_tag user.user_photo %
Much cleaner that way, since you don't have to look in the helper for the HTML
or the accessor logic, rather you look for HTML in the view and logic in the
model, as Rails intends.

[Rails] Re: JIRA anyone?

Re: [Rails] JIRA anyone?
Greenhopper is a Jira plugin for Scrum teams - Pivotal Tracker, Rally and others get better reviews from users I have heard from. Where I work we do a lot of Jira automation using the SOAP listener, both with ruby and java - I have used jira4r (I posted a gemspec for it on the Atlassian site if I am remembering correctly) - I think the error you are getting means you do not have a supported XML processor installed ... All the gem does is if I remember correctly is store the session key returned from login in an instance variable and then add that parameter to every outgoing request that is made - it is pretty tiny code-wise.

[Rails] Re: routes issues with rails3
You should define it as
:on = :collection
Problem is you defined it as :member, so it expects an id to be
passed, so the expected url would look like /home/:id/login
Hope this helps!

You might be better to use datetime column types rather than a separate date and time. Then you will just need to check the uniqueness of the datetime values. You can easily then extract the date and time separately for display purposes. Colin -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

SELECT pi.number, p.name \pname\, u.name, a.result, a.exec_time,
a.used_memory, a.time - c.start_time \time\
FROM attempts a
INNER JOIN problem_infos pi ON (pi.id = a.problem_info_id)
INNER JOIN problems p ON (p.id = pi.problem_id)
INNER JOIN users u ON (u.id = a.user_id)
INNER JOIN contests c ON (c.id = pi.contest_id)
WHERE (pi.contest_id = 1)
ORDER BY a.time DESC;)
---
The first query is better and it is write easy, but it makes several
small requery to database. If i am right, i use resources of Ruby on
Rails.
The seond query make one requery to database.
I want to use the first query, but it works longer than the second. How
to right query, using join, but it mustn't make several requery.

[Rails] Accessing raw cookie values?
Hi there, I realized today that rails does some automatic (url?) decoding of cookie values. I assume it is because if you set a cookie, the value is also url encoded. The problem is that the cookie specification does not seem to specify the need of encoding. Thus, if an external application sets a cookie (e.g. a domain cookie where apps are on multiple subdomains) it can happen that it is decoded although it was not encoded. A simple example is that a non-encoded cookie containing a+b results in the ruby string a b when accessed in Rails. I wanted to ask if anyone knows any details about this behavior or if it is possible to access the raw string? Thanks a lot, Christoph -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group. To post to this group, send email to rubyonrails-talk@googlegroups.com.

[Rails] customise the color of link_to text
I have a section of link to button's in my index that have associated
CSS which has a black background. Despite me in the css specifying the
text to be the color white it is staying just plain black.

table width=1160

th%= link_to 'Playstation 3', games_path(:console =
'Playstation 3')%/th
.
/thead
/table

font-weight: normal;
color: #FF;
line-height: 40px;
margin-bottom: 10px;

[Rails] Re: customise the color of link_to text
Well a link_to creates a regular link in HTML so you need to style the a
tag.
#table-3 th a {
color: .
}
Or if you want to style both regular text and links in that part:
#table-3 th,
#table-3 th a {
color: ...
}

[Rails] OpenSSL on rails 2
Hi list, It's been a while since I looked at rails and I am a but rusty. I'm looking for a nudge in the right direction if anyone would be so kind to help me. I'm looking at something I did a few years back that I need to review and upgrade. The last time I looked at this we were on Rails 2.0.2 so that's what this code is for. So I am trying to get it running on that environment to start off. I have a RVM environment running rails 2.0.2 on ruby 1.8.7.

[Rails] link_to alphabetical search
Hi all,
I have a link_to method in rails for each letter of the alphabet (early
days yet, will put it in a loop later). I have the same for a console on
another page and that one works fine but the one on my page for the
letters does not.
I have the following in my model:
def index
user_relation = case params[:username].present?
when true then User.where(:username = params[:username])
else User
end
@users = user_relation.paginate :page=params[:page], :order =
'created_at desc', :per_page = 10
end
and this is an example in my index:
%= link_to 'A', users_path(:username = 'A'), {:style='color:#FF',
:class = tabel-3}%
Now if I click on A it does not return any results despite there being
many users with the letter A but if I was to for example put in the
brackets the name AdrianShaw (one of the users in my database) and click
A it would return that exact user. What it seems to be doing is search
but only for exact match results, anything less than the full word and
it does not return.
How would I go about doing this so that it gets all users with the first
letter A and so on?
Thanks
Christopher Jones

[Rails] setting up a vps for rails: looking for advice, tutorials, etc.
i am trying to learn how to setup and maintain a vps for some rails apps. i have used shared and managed hosting but now i am looking for the freedom and flexibility a vps offers. i signed up with linode to give me something to play around with until i feel comfortable to deploy my live apps to a vps. i want to learn best practices and how to do things right. initially i plan on hosting only a few smaller rails apps, but hopefully more in the future. i have searched google and read quite a bit, but was wondering if any of the rails professionals could point me in the direction of some good resources or give their input directly? i have also read through many of the stackscripts and some seem good, others don't even setup a firewall. here are some of the questions that have been going through my head that i have been trying to figure out. security -all rails apps under one user or separate user for each app? -is it necessary to change the ssh port? -how insecure is keeping ssh passwords enabled? -fail2ban? keeping the software up to date -apt will help keep the os and some apps up to date -how to easily keep compiled software updated like nginx? -how about ruby, gems, rails,... which of the following is better for rails apps which linux distro? 32bit vs 64bit? iptables vs ufw? apache vs nginx? mysql vs postgresql? passenger vs unicorn? is it a good or bad idea to use rvm on a server? rvm per user or system wide? what are some good strategies for backing up the server in case of failure? how do you monitor the resource usage to see if more ram or cpu is needed? how much of what do you log and how do you monitor the logs? thank you, scott -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] why does self.included work but not include/extend
I have interesting situation. a.rb #file class A include M end b.rb #file module M include X extend Y end module X def instance_method end end module Y def class_method end end A.class_method = undefined method class_method Thats strange because what I expect to happen is module M extends Y so those class methods of Y are copied into A, and hence the A object can access those class methods. But thats not what happened. Ruby couldnt find the class methods. Yet when I change to this it worked: a.rb #file class A include M end module M def self.included(base) base.send :include, X base.send :extend, Y end module X def instance_method end end module Y def class_method end end end A.class_method = nil So this works, and the only difference is that X and Y modules are declared in M. Also I use the included hook which gets called when M is included in class A, and then passes A into argument list. Then we dynamically send methods (since include is a private method of A) of A, particuarly the inclue and extend methods passing our modules as arguments. And now it works. But why didnt the first example work? thanks for response -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Bundler could not find compatible versions for gem railties:
I have the same problem. Here is an attempt to recreate the steps that caused it for me: Platform Windows 7 x64 - installed latest git (1.7.8.msysgit.0) - installed RailsInstaller (ruby 1.9.3) - installed DevKit - installed Heroku tools w/o Git I also have cygwin installed (not sure that is relevant but there have been issues with mingw32 apps). After installing all of the above I did the following: - Ran gems update - Followed Rails Tutorial exactly The tutorial process failed at the step for pushing to Heroku with error shown in the original question. I tried to work around the problem: * Tried changing Gemfile back to ~ versions * Deleted extra local versions of installed railsties and sass-rails, reinstalled only the specified versions * Tried using sass-rails 3.2.4 in Gemfile in hopes the dependency would correct itself Nothing worked. Sometimes a local bundle update/bundle install would work, sometimes it would fail. It seemed to always work from a git bash window and cmd.exe failed most of the time. But no matter what the outcome locally, when I tried to push to Heroku it always gave the error message above. Rubygems.org clearly shows that the sass-rails dependency on railties should be on 3.2.0.beta so something funky is going on. Just wish I knew what it is. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Re: [Rails] Do I need WEBrick?
I agree with Adrian, it seems that the error is complaining about mySQL not being installed. Are you sure you have the mySQL server installed on your system? if yes Then make sure to add the 'mysql2' gem to your gemfile. Cheers!! 2012/2/29 Adrian Caceres cacere...@gmail.com Sure the problem is WEBrick? Error message seems to be complaining about mysql. Did you install mysql?

[Rails] Re: Are there any clean alternatives to Unicorn for HTTP streaming?
Unicorn is clean. What I should have wrote is In addition to Unicorn, are there any other HTTP Servers, for Ruby on Rails, that cleanly support HTTP streaming? Thank you!

[Rails] Re: rails and javascript
There are a few ways to do this. If you are looking for an ajax
response you can do the following:
(this is an example with a new action)
%= form_for Model.new, :remote = true do |f| %
divYour Label/div
div
%= f.collection_select(:some_id, Model.all, :id, :name, :class =
'yourclass' %
/div
% end %
Then in your javascript do something similar to:
$('select#model_some_id').bind({
click:function () {
// do something when it's clicked
},
keydown:function () {
// do something when a key is pressed down in the select
},
keyup:function () {
// do something when a key is pressed up in the select
}
});
This handles most of the browser events you'll find in Mozilla, IE,
Safari, etc. as far as handling events. Some change events are not
noticed by Mozilla (for instance if someone is using drop down arrows
while in a select field).
There are quite a few ajax tutorials out there.

[Rails] Testing selector order in RSpec
Could someone point me to a reference that explains how I would test the order of elements on an HTML page? For example, in RSpec I would like to verify that the content of one p element appears before the content of another. response.should have_selector(p, :content = Should appear first) response.should have_selector(p, :content = Should appear second) The two lines above test that the 2 contents appear, but I don't know how to test that the first content appears before the second.

[Rails] Re: how to pre-select a collection_select inside a form_for?
I'm curious what you have as far as relationships in your FriendType
model? Does it belong_to :user?
If so,
%= f.collection_select(:user_id, FriendType.all, :id, :name, options=
{:prompt = false}, {:class = 'yourCustomClass'}) %
Hope that helps you out.
