  • Liquid templates - accessing members by name

    - by egarcia
    I'm using Jekyll to create a new blog. It uses Liquid underneath. Jekyll defines certain "variables": site, content, page, post and paginator. These "variables" have several "members". For instance, post.date will return the date of a post, while post.url will return its url. My question is: can I access a variable's member using another variable as the member name? See the following example: {% if my_condition %} {% assign name = 'date' %} {% else %} {% assign name = 'url' %} {% endif %} I have a variable called name which is either 'date' or 'url'. How can I make the liquid equivalent of post[name] in ruby? The only way I've found is using a for loop to iterate over all the pairs (key-value) of post. Beware! It is quite horrible: {% for property in post %} {% if property[0] == name %} {{ property[1] }} {% endif %} {% endfor %} Argh! I hope there is a better way. Thanks.

  • Include FileUtils raises an error

    - by Bilal Aslam
    I am trying to install CruiseControl.rb on an Amazon EC2 instance. I get this error in the mongrel log: /data/cruisecontrol/releases/20100313003145/vendor/rails/activesupport/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant ProjectsMigration::FileUtils (NameError) This error is raised in a file called projects_migration.rb: http://gist.github.com/331025. Check out line 3, which I have commented out. If you remove the comment-out, you will get this error as well. The weird part: from ruby script/console I can include FileUtils just fine!

  • Wrapper around bash, control STDIN and STDOUT

    - by blinry
    I would like to talk to a interactive bash process. Here is an example, so you know what I want to archieve: Program starts a new bash process. User types "ls" into my program. Program sends this command to the bash process. Program reads all available output of the bash (including the prompt) and displays it back to the user. GOTO 1 As you can guess, there is much room for nifty manipulations here and there... ;-) It would be wonderful if this also worked for subprocesses (started by the bash process) and curses-based programs. I would like to implement this functionality in Ruby, and already have experimented with IO.popen, but strange things happen. You are also welcome to do this in other languages.

  • github url style

    - by Alex Le
    Hi all, I wanted to have users within my website to have their own URL like http://mysite.com/username (similar to GitHub, e.g. my account is http:// github. com/sr3d). This would help with SEO since every profile is under the same domain, as apposed to the sub-domain approach. My site is running on Rails and Nginx/Passenger. Currently I have a solution using a bunch of rewrite in the nginx.conf file, and hard-coded controller names (with namespace support as well). I can share include the nginx.conf here if you guys want to take a look. I wanted to know if there's a better way of making the URL pretty like that. (If you suggest a better place to post this question then please let me know) Cheers, Alex

  • How to handle HTTPStatus Response 201 with AS3 / Flash / SWFUpload

    - by Praveen Sharma
    Hey all. I'm using SWFUpload on a Rails site to allow for MP3 Uploads direct to Sound Cloud. To avoid having to first upload a large file to my server and push to Sound Cloud, I'm hitting their API directly via SWFUpload, passing necessary OAuth token data. Everything works - EXCEPT - Flash can't handle the HTTP response code that Sound Cloud's API returns (201). This ALWAYS triggers an unhandled IO Error with Flash. Even though SWFUpload allows me to override that in the JS, it breaks any response data (the URI to the uploaded file). Does anyone know how I could somehow intercept the 201 code so that I can make it a 200 code for flash? I'm at a loss at how I can avoid this IO Error. I've tried try/catch statements around everything and have even recompiled SWFUpload to try new things to no avail. Any help would be greatly appreciated.

  • Rub, regex, sentences

    - by Perello
    I'm currently building a code generator, which aim to generate boiler plate for me once i wrote the templates and/or translations, whatever the language i have to work with, and it has an educationnal part :p. So i have a problem with a regex in ruby. The regex aim to select whatever is between {{{ and }}}, so i can generae functions according to my needs. My regex is currently : /\{\{\{(([a-zA-Z]|\s)+)\}\}\}/m My test data set {{{Demande aaa}}} = {{{tagadatsouintsouin tutu}}} The results are : [["Demande aaa", "a"], ["tagadatsouintsouin tutu", "u"]] So the regex pick each time the last character twice. But, that's not exactly what i want, my need is more about this : /\{\{\{((\w|\W)+)\}\}\}/m But this as a flaw too, the results : [["Demande aaa}}} = {{{tagadatsouintsouin tutu", "u"]] Whereas, i wish to get [["Demande aaa"],["tagadatsouintsouin tutu"]] Any ideas to correct theses regex ? I could use 2 sets of delimiters, but it won't learn me anything.

  • Parsing atom/rss feed containing multiple <link> tags with Haml on RoR

    - by fenderplayer
    So, firstly, heres an atom feed snippet which i am trying to parse: // http://somelink.com/atom <feed xmlns="http://www.w3.org/2005/Atom"> <entry> <title>Title Here</title> <link href="http://somelink.com/link1&amp;amp;ref=rss" rel="alternate" /> <link href="http://somelink.com/link2&amp;amp;ref=rss" rel="tag:somelink.com/apply_url"/> ... </entry> i pull the atom feed like so, // In controller index method @rss = SimpleRSS.parse open('http://somelink.com/atom') Then i output the response in the view, which i am writing using haml, as follows: - @rss.entries.each do |item| .title-div = item.title .title-link = item.link //outputs the first link I could run a second loop for the links but is there a way to get the second link without it? Like reading the "rel" attribute and outputting the correct link? How do i do this in haml/rails?

  • Mysql out of disk space

    - by Paddy
    I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

  • Technology stack for very frequent gps data collection

    - by gvaswani
    I am working on a project that involves gps data collection from many users (say 1000) every second (while they move). I am planning on using a dedicated database instance on EC2 with the mysql persistent block storage and run a ruby on rails application with nginx frontend. I haven't worked on such data collection application before. Am I missing something here? I will have a another instance which will act as application server and use the data from the same EBS. If anybody has dealt with such a system before, Any advise would be much appreciated?

  • Shell Script Sequencing with Rake

    - by Haseeb Khan
    Hi All, I am working on a rake utility and want to implement something mentioned below: There are some shell commands in a sequence in my Rake file. What I want is that the sequence should wait for the previous command to finish processing before it moves to the next one. sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end sh "git push heroku master" So, in the above example what I want is that sh "git push heroku master" shouldn't be executed until the processing in the sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end is completed. Also another nice to have would be that if I can store the output of the shell command in a Ruby variable so it can be used in further manipulation if required. Looking forward to a reply from the fellow community member shortly. Thanks in advance.

  • Running tasks in the background with lower CPU priority

    - by Brendon Muir
    I have a feature in my CMS that allows a user to upload a zip file full of images and the server will extract them and insert each one into an image gallery. I've noticed that this grinds up the CPU quite severely and causes other requests to slow down. I'm thinking of using the delayed_job plugin to delegate each image addition into the background, but I also want to give that process a lower CPU priority so that it doesn't bog down the server. I'm pretty confident in the delaying part of the exercise, but the throttling part is where I'm stuck. Is there a ruby way of lowering the priority of a method call? It's the image resizing that causes the CPU chew. Any ideas welcome :)

  • Overriding as_json has no effect?

    - by Ola Tuvesson
    I'm trying to override as_json in one of my models, partly to include data from another model, partly to strip out some unnecessary fields. From what I've read this is the preferred approach in Rails 3. To keep it simple, let's say I've got something like: class Country < ActiveRecord::Base def as_json(options={}) super( :only => [:id,:name] ) end end and in my controller simply def show respond_to do |format| format.json { render :json => @country } end end Yet whatever i try, the output always contains the full data, the fields are not filtered by the ":only" clause. Basically, my override doesn't seem to kick in, though if I change it to, say... class Country < ActiveRecord::Base def as_json(options={}) {foo: "bar"} end end ...I do indeed get the expected JSON output. Have I simply got the syntax wrong?

  • How do I change JAVASCRIPT_DEFAULT_SOURCES for my application?

    - by Adam Lassek
    When you call javascript_include_tag :defaults you usually get: prototype.js, effects.js, dragdrop.js, and controls.js. These are stored in a constant in ActionView::Helpers::AssetTagHelper called 'JAVASCRIPT_DEFAULT_SOURCES`. My application uses jQuery, so I want to replace the Prototype references with something more useful. I added an initializer with these lines, based on the source code from jRails: ActionView::Helpers::AssetTagHelper::JAVASCRIPT_DEFAULT_SOURCES = %w{ jquery-1.4.min jquery-ui jquery.cookie } ActionView::Helpers::AssetTagHelper::reset_javascript_include_default But when I do this, I get: warning: already initialized constant JAVASCRIPT_DEFAULT_SOURCES during startup. What's the correct way of changing this value? In the source code it checks for the constant before setting it, but apparently that happens before it runs the initializer scripts. The Rails 3.0 release will provide much greater flexibility with choice of JS libraries, so I guess this is a problem with an expiration date.

  • the rmagick manual is quite vague. can you help me by changing a pictures filetype and size?

    - by Joern Akkermann
    Hi, it's about RMagick with Ruby On Rails. I do the following: image = params[:image] # params[:image] is the image from the file-form. name = image.original_filename.scan(/[^\/\\]+/).last name = dir + t.day.to_s + t.month.to_s + t.year.to_s + t.hour.to_s + t.min.to_s + t.sec.to_s + name f = File.new(name, "wb") f.write image f.close image = Magick::Image.read(name) image = image.resize_to_fit(200, 250) f = File.new(name, "wb") f.write image.to_blob f.close Do I really need to first save and then change it? And how about changing not only the size, changing also the Filetype? I want a JPG with 60% quality. Please help me. Yours, Joern.

  • Database on the fly with scripting languages

    - by afilatun
    I have a set of .csv files that I want to process. It would be far easier to process it with SQL queries. I wonder if there is some way to load a .csv file and use SQL language to look into it with a scripting language like python or ruby. Loading it with something similar to ActiveRecord would be awesome. The problem is that I don't want to have to run a database somewhere prior to running my script. I souldn't have additionnal installations needed outside of the scripting language and some modules. My question is which language and what modules should I use for this task. I looked around and can't find anything that suits my need. Is it even possible?

  • Sqs vs SqsGen2 using RightScale right_aws GEM

    - by Fitter Man
    I'm trying to use the right_aws (1.10.0) GEM with Rails, and I've reduced my problem to a 3-line irb session. The following works require 'rubygems' require 'right_aws' sqs = RightAws::Sqs.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") while this fails require 'rubygems' require 'right_aws' sqs = RightAws::SqsGen2.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") with NameError: uninitialized constant RightAws::SqsGen2. I see the class definition in the GEM source, the documentation is old but seems accurate, but I can't figure out what I'm doing wrong. And while you're at it, is there any reason if I'm building something new, I'd want to use the older interface?

  • Should I stop redirecting after successful POST or PUT requests?

    - by Andres Jaan Tack
    It seems common in the Rails community, at least, to respond to successful POST, PUT or DELETE requests by redirecting instead of returning success. For instance, if I PUT a legal change to my user profile, the idiomatic response would be a 302 Redirect to the profile page. Isn't this wrong? Shouldn't we be returning 200 OK from the request? Or a 201 Created, in the case of a POST request? Either of those, in the HTTP/1.1 Status Definitions are allowed to (or required to) include a response, anyway. I guess I'm wondering, before I go and "fix" my application, whether there is there a darn good reason why the community has gone the way of redirects instead of successful responses.

  • How to encrypt the mobile configuration profiles in iOS (in OTA deployments)?

    - by user1353477
    I am trying to sign and encrypt .mobileconfig profiles for iOS devices. Signing works perfectly using openssl::pkcs7 sign function in ruby, however using encrypt function, I get an encrypted data but Safari fails to install the profile saying "Invalid Profile". There are two questions in this regard: Which data from the .mobileconfig profile is actually encrypted that goes into the .. section of the EncryptedPayloadContent ? Is the data in binary format (.der) or base64 encoded? Any help in this regard would be helpful as APPLE severly lacks any documentation in encrypting the profiles.
