jQuery-Facebox - Popup is not working after repaint from AJAX

- by Bragaadeesh

Hi I am having a set of Links in my page and I have attached the facebox jQuery functionality so that whenever a link is pressed, it will get a nice popup <a href="coach_selector_popup?day=<%= day %>&hour=<%= hour %>" rel="facebox"> Below is the script that I use for 'facebox'ing. <script type="text/javascript"> jQuery(document).ready(function($) { jQuery('a[rel*=facebox]').facebox() }) </script> The above is working fine. But when I render it again on response to some AJAX call, the functionality is getting lost, meaning when I click on the link I am redirected to a page instead of a facebox popup. I know that I need to do something when I repaint, can someone point me to the right direction?

sqlite database, RoR and VCS

- by ryanprayogo

What is the common way of dealing with the development.sqlite3 files with VCS (in particular, git)? If I commit this file to the VCS, will it be merged with another developer's copy? Or should each developer run the db:migrate task each time a new migration file is created?

Passenger: RailsBaseURI case sensitive?

- by Bryan Roth

I used Passenger to deploy a RoR app to a sub URI on my domain. The problem I'm facing is that the sub URI seems to be case sensitive. Navigating to http://mydomain.com/RailsApp resolves fine. However, if I go to http://mydomain.com/railsapp, http://mydomain.com/railsApp, or any other variation, I get a 404 error. How can these requests using different casings get resolved correctly? Here is my Apache configuration file: <VirtualHost *:80> ServerName mydomain.com ServerAlias www.mydomain.com DocumentRoot /www/mydomain/public <Directory "/www/mydomain/public"> RailsEnv "production" Order allow,deny Allow from all </Directory> RailsBaseURI /RailsApp <Directory "/www/RailsApp/public"> RailsEnv "development" Options -MultiViews </Directory> </VirtualHost> Any help is much appreciated. Thanks!

How can I quote strings in SASS?

- by Stavros Korokithakis

I'm using SASS to generate a @font-face mixin, however this: =remotefont(!name, !url) @font-face font-family = !name src = url(!url + ".eot") src = local(!name), url(!url + ".ttf") format("truetype") +remotefont("My font", "/myfont.ttf") becomes this: @font-face { font-family: My font; src: url(/myfont.ttf.eot); src: local(My font), url(/myfont.ttf.ttf) format(truetype); } No matter how much I try, I can't have it quote either "My font" (with "!name") or "truetype" (it removes the quotes). Any ideas on how I can do this?

cloned project from github. heroku does not work

- by ratan

I cloned a project from github over to my desktop. I used to work on it form my laptop. However, on laptop heroku does not seem to work for this app eventhough i have it installed. First problem: heroku open >No app specified. >Run this command from app folder or set it adding --app <app name> I did not have to specify the --app on my laptop. Because I guess I did command heroku create initially on the lapop. Second Probelm: git push heroku master gives errors fatal: 'heroku' does not appear to be a git repository fatal: The remote end hung up unexpectedly and heroku list says ! This version of the heroku gem has been deprecated. ! Please update it by running: gem update heroku

How do I.. get a value for time at 9:00am local, regardless of the timezone?

- by ander163

In my app, I need to set a variable for a start time to be 9:00 a.m. local, wherever the user is located. I have a timezone variable for each user and the save and retrieve are all working. But I need to set a variable when I create a new event to be 9:00 am in the user's local time zone. My current method uses the local time of the server, then makes the adjustments for the individual user's time zone. I don't know what I don't know - is there a command to create the value for "Today's date at 9:00 am where you are"? My current code is: t = Time.now.to_date.beginning_of_day + 11.hours (forcing the 2 hour offset between my primary user and the server in a different timezone).

Thin, Sinatra, and intercepting static file request to do CAS authentication

- by Kenny Peng

I'm using the casrack-the-authenticator gem for CAS authentication. My server is running Thin on top of Sinatra. I've gotten the CAS authentication bit working, but I'm not sure how to tell Rack to intercept "/index.html" requests to confirm the CAS login, and if the user is not allowed to view the page, return a HTTP 403 response instead of serving the actual page. Does anyone have experience with this? Thanks. My app: class Foo < Sinatra::Base enable :sessions set :public, "public" use CasrackTheAuthenticator::Simple, :cas_server => "https://my.cas_server.com" use CasrackTheAuthenticator::RequireCAS end My rackup file: require 'foo' use Rack::CommonLogger use Rack::Lint run Foo

heroku time zone problem, logging local server time

- by Ole Morten Amundsen

UPDATE: Ok, I didn't formulate a good Q to be answered. I still struggle with heroku being on -07:00 UTC and I at +02:200 UTC. Q: How do I get the log written in the correct Time.zone ? The 9 hours difference, heroku (us west) - norway, is distracting to work with. I get this in my production.log (using heroku logs): Processing ProductionController#create to xml (for 81.26.51.35 at 2010-04-28 23:00:12) [POST] How do I get it to write 2010-04-29 08:00:12 +02:00 GMT ? Note that I'm running at heroku and cannot set the server time myself, as one could do at your amazon EC2 servers. Below is my previous question, I'll leave it be as it holds some interesting information about time and zones. Why does Time.now yield the server local time when I have set the another time zone in my environment.rb config.time_zone = 'Copenhagen' I've put this in a view <p> Time.zone <%= Time.zone %> </p> <p> Time.now <%= Time.now %> </p> <p> Time.now.utc <%= Time.now.utc %> </p> <p> Time.zone.now <%= Time.zone.now %> </p> <p> Time.zone.today <%= Time.zone.today %> </p> rendering this result on my app at heroku Time.zone (GMT+01:00) Copenhagen Time.now Mon Apr 26 08:28:21 -0700 2010 Time.now.utc Mon Apr 26 15:28:21 UTC 2010 Time.zone.now 2010-04-26 17:28:21 +0200 Time.zone.today 2010-04-26 Time.zone.now yields the correct result. Do I have to switch from Time.now to Time.zone.now, everywhere? Seems cumbersome. I truly don't care what the local time of the server is, it's giving me loads of trouble due to extensive use of Time.now. Am I misunderstanding anything fundamental here?

Building simple Reddit scraper

- by Bazant Fundator

Let's say that I would like to make a collection of images from reddit for my own amusement. I have ran the code on my development env and It haven't gone past the first page of posts (anything beyond requries the after string from the JSON. Additionally, When I turn on the validation, the whole loop breaks if the item doesn't pass it, not just the current iteration. I would be glad If you helped me understand mistakes I made. class Link include Mongoid::Document include Mongoid::Timestamps field :author, type: String field :url, type: String validates_uniqueness_of :url, # no duplicates validates :url, uniqueness :true end def fetch (count, after) count_s = count.to_s # convert count to string link = "http://reddit.com/r/aww/.json?count="+count_s+"&after="+after #so it can be used there res = HTTParty.get(link) # GET req. to the reddit server json = JSON.parse(res.body) # Parse the response if json['kind'] == "Listing" then # check if the retrieved item is a Listing for i in 1...(count) do # for each list item datum = json['data']['children'][i]['data'] #i-th element properties if datum['domain'].in?(["imgur.com", "i.imgur.com"]) then # fetch only imgur links Link.create!(author: datum['author'], url: datum['url']) # save to db end end count += 25 fetch(count, json['data']['after']) # if it retrieved the right kind of object, move on to the next page end end fetch(25," ") # run it

What does this code do?

- by Senthil

I found this in Ryan Bates' railscast site, but not sure how it works. #models/comment.rb def req=(request) self.user_ip = request.remote_ip self.user_agent = request.env['HTTP_USER_AGENT'] self.referrer = request.env['HTTP_REFERER'] end #blogs_controller.rb def create @blog = Blog.new(params[:blog]) @blog.req = request if @blog.save ... I can sort of understand what he is doing. But am confused with the req=(request) line. Any help is appreciated. Thanks

Why are my basic Heroku Apps Taking 2 seconds to load?

- by viatropos

I have created two very simple heroku apps to test out the service, but it's often taking several seconds to load the page when I first visit them: Cropify - Basic Sinatra App (on github) Textile2HTML - Even more basic Sinatra App (on github) All I did was create a simple sinatra app and deploy it. I haven't done anything to mess with or test the heroku servers. What can I do to improve response time? It's very slow right now and I'm not sure where to start. The code for the projects are on github if that helps. Thanks so much.

How do I silence the following RightAWS messages when running tests

- by Laurie Young

I'm using the RighAWS gem, and mocking at the http level so that the RightAWS code is being executed as part of my tests. When this happens I get the following output ....New RightAws::S3Interface using per_request-connection mode Opening new HTTP connection to s3.amazonaws.com:80 .New RightAws::S3Interface using per_request-connection mode . Even though all the tests pass, when I do have errors its harder to scan them because of this output. is there a nice way to silence it?

How to upload a file with watir and IE?

- by karlthorwald

I am writing a watir script to test an upload form. But the script does not automatically choose the file that is to be uploaded from my harddrive. Instead IE stops with the file chooser dialog open. As soon as I manually select the to be uploaded file in the dialog and click ok, watir continues as desired. I wonder why it stops. This is from my watir script: ie.file_field(:name, 'upload').set("s:\\localwatir\\Test_Pdf.pdf") ie.button(:name, 'submit').click I got the code from this page: http://wiki.openqa.org/display/WTR/File+Uploads This is the form: <form name="form1" enctype="multipart/form-data" method="post" action="uploadlegacy.php"> <input type="file" name="upload" size="30"> <input type="submit" name="submit" value="upload"> </form> I have found this manual http://svn.openqa.org/svn/watir/trunk/watir/unittests/filefield_test.rb also, but as I do not know what $htmlRoot stands for, I cannot really follow it. Does that mean, I have to put some "file///" into the parameter for set()? If so, how exactly? I am using IE 6 for the testing.

if_attribute on declarative authorization. STUCK FOR DAYS!!!

- by Victor Martins

I can't seem to find a solution for this problem :s I have a many to many relationship like this: A user has_many organizations through affiliations and vice versa. I'm using declarative organizations and I only want a user to edit a particular organization if he is affiliated and the affiliationtype attribute of affiliation is a particular value. So affiliations has 3 columns , user_id, organization_id and affiliationtype_id I can do: o = Organization.find(:first) o.affiliatons[0].user and get the user now I wish to do this: has_permission_on [:organizations], :to => :edit do if_attribute (...) end That if_attribute should see if the current user is the organization.affiliation[?].user and if the organization.affiliation[?].affiliationtype_id = "3" I hope this is syntax issue ... I really need to get this working. Thanks in advance.

I need to modify the code of a third-party gem, where and how to do?

- by Freewind

I'm building a website based on RoR, and using a third-party gem "devise". I have used rake gems:unpack to unpack the "devise" to my "vendor/gems" directory. Now, I found the method "SessionsController.create" provided by "devise" is not fit my requirement, and I want to modify it. But I don't know what it is best way: just modify the method SessionsController.create" directly? create another SessionsController and override the "create" method?

Validate a belongs to association in a build situation.

- by Victor Martins

I have a Mission model that has_many Task, and the Task belongs_to Mission For security I've made this validation on the Task Model: validates_presence_of :mission_id validates_numericality_of :mission_id But the problem is that when create a Mission and add tasks like this: @mission.tasks.build The validation returns error, because the mission id on the task is null ( the mission wasn't yet created ) If I delete the validation, the Mission and Task is created successfuly, but how can I keep the validation and still have this work? I could do a callback after the save, but I don't think that's right, because I don't want to save Tasks without a mission_id. P.S. I'm hidding my mission field on the form. If I have it visible, it will show the currect mission and everything is ok. But if I hidde it the error happens. <%= f.hidden_field :mission, :label => "Missão" %> Is the form reseting the attributes given by the controller on the new action?

How do I add a condition to all ActiveRecords Queries for a particular model?

- by Kyle West

I am using the sentient_user gem to have access to the current_user object in my application. I want to override the default ActiveRecordBase queries to scope them to the current user. For instance, I don't want my users looking at, deleting, modifying other user's orders. I feel like I should be able to override a single (or couple) ActiveRecordBase methods to accomplish this, but I don't know which or how. Thanks in advance.

vlad the deployer: why do I need a scm folder?

- by egarcia

I'm learning to use vlad the deployer and I've got a question. Since I'm still learning I don't know what is pertinent to the question and what isn't, so please bear with me if I'm a little verbose. I've got 2 environments for a new application (test and production) besides my development machine. I've figured out this way to do the initial setup in my vlad.rake: namespace :test task :set set :domain, 'test.myserver.com' end end namespace :production task :set set :domain, 'www.myserver.com' end end This way I can have environment-specific stuff inside the namespaces, and still have shared tasks. For example, this would be the initial setup for test: rake vlad:test:set vlad:setup vlad:update This creates the following folders on my test server: releases/ scm/ shared/ current -> symlink to last release (inside the releases folder) My question is: what's the point of the scm folder? Every time I do vlad:update, the following happens: svn checkout on the scm/ folder above svn export on the /releases/{date} folder update current symlink So scm is a copy of my repository... but then there's an "export" copy of the repository on /releases/{date}. And that is the one used by the application... scm doesn't seem to be used by anyone? Wouldn't I be just fine without the scm folder?

Mechanize Javascript ...

- by Horace Ho

I try to submit a form by Mechanize, however, I am not sure how to add necessary form valuables which are done by some Javascript. Since Mechanize does not support Javascript yet, and so I try to add the variables manually. The form source: <form name="aspnetForm" method="post" action="list.aspx" language="javascript" onkeypress="javascript:return WebForm_FireDefaultButton(event, '_ctl0_ContentPlaceHolder1_cmdSearch')" id="aspnetForm"> <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__LASTFOCUS" id="__LASTFOCUS" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/..." /> <script type="text/javascript">  </script> <script language="javascript">  </script> ... <a href="JavaScript:_linkedClicked('123456','_ctl0:ContentPlaceHolder1:Link', '',0,1);">123456</a> ... </form> I tried to add the 2 variables: page.forms.first['__EVENTTARGET'] = '_ctl0:ContentPlaceHolder1:Link' page.forms.first['__EVENTARUGMENT'] = '123456' and submit the form: page.forms.first.click_button(page.forms.first.buttons.first) The result returned only (re)show the current list of links as if I have not clicked on any of the links. Any help will be appreciated. Thanks!

Heroku taps push weirdness...

- by holden

I have the strangest experience using taps to move data between my machine and heroku. It works fine except that it seems to loose 0s directly behind the decimal place for my geo coordinates. Ie 50.0519322 for some reason gets set to 50.519322... no idea why. When I pull the data from the remote location ie. heroku db:pull... it works fine, all decimal places intact on my machine, however, when i push it back to the remote server it loses these zeros. Especially directly behind the decimal place, though I haven't noticed it elsewhere yet. At first I was storing the lat and lng as simply numeric but refined it to: change_column :places, :lat, :numeric, :precision => 15, :scale => 10 change_column :places, :lng, :numeric, :precision => 15, :scale => 10 With no result, any ideas what's going on? From the console on the remote server i get the lat as being: #<BigDecimal:2aebcc5967c0,'0.50519322E2',18(18)> and my machine as: #<BigDecimal:10232f7c8,'0.50519322E2',12(16)> which is also odd, the second one because it shows up as 50.0519322 when i edit it thru my view but when i do to_f via console it gives me 50.519322
