  • How do I set a time in a time_select view helper?

    - by brad
    I have a time_select in which I am trying to set a time value as follows; <%= f.time_select :start_time, :value => (@invoice.start_time ? @invoice.start_time : Time.now) %> This always produces a time selector with the current time rather than the value for @invoice.start_time. @invoice.start_time is in fact a datetime object but this is passed to the time selector just fine if I use <%= f.time_select :start_time %> I guess what I'm really asking is how to use the :value option with the time_select helper. Attempts like the following don't seem to produce the desired result; <%= f.time_select :start_time, :value => (Time.now + 2.hours) %> <%= f.time_select :start_time, :value => "14:30" %>

  • What is causing Apache2 to display PHP as plain text in this config file?

    - by rxgx
    I am trying to run PHP and Rails in the same virtual host, however, PHP is being displayed as plain/text. When I create a test host without all the rewrites and proxy-ing, Apache2 will process the PHP as desired. Where in my config file have I gone wrong? <VirtualHost *:80> #ServerName staging.domain.com #ServerAlias www.domain.com DocumentRoot /home/demo/vhosts/domain/public <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/demo/vhosts/domain/public> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> RewriteEngine On <Proxy balancer://thinservers> BalancerMember http://127.0.0.1:5000 BalancerMember http://127.0.0.1:5001 BalancerMember http://127.0.0.1:5002 </Proxy> # Redirect all non-static requests to thin RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://thinservers%{REQUEST_URI} [P,QSA,L] ProxyPass / balancer://thinservers/ ProxyPassReverse / balancer://thinservers/ ProxyPreserveHost on <Proxy *> Order deny,allow Allow from all </Proxy> # Custom log file locations ErrorLog /home/demo/vhosts/domain/log/error.log CustomLog /home/demo/vhosts/domain/log/access.log combined </VirtualHost>

  • Rails 1.0 - Using composed_of gives me a wrong number of arguments (1 for 5) error

  • Logging with log4j on tomcat jruby-rack for a Rails 3 application

    - by John
    I just spent the better part of 3 hours trying to get my Rails application logging with Log4j. I've finally got it working, but I'm not sure if what I did is correct. I tried various methods to no avail until my various last attempt. So I'm really looking for some validation here, perhaps some pointers and tips as well -- anything would be appreciated to be honest. I've summarized all my feeble methods into three attempts below. I'm hoping for some enlightenment on where I went wrong with each attempt -- even if it means I get ripped up. Thanks for the help in advance! System Specs Rails 3.0 Windows Server 2008 Log4j 1.2 Tomact 6.0.29 Java 6 Attempt 1 - Configured Tomcat to Use Log4J I basically followed the guide on the Apache Tomcat website here. The steps are: Create a log4j.properties file in $CATALINA_HOME/lib Download and copy the log4j-x.y.z.jar into $CATALINA_HOME/lib Replace $CATALINA_HOME/bin/tomcat-juli.jar with the tomcat-juli.jar from the Apache Tomcat Extras folder Copy tomcat-juli-adapters.jar from the Apache Tomcat Extras folder into $CATALINA_HOME/lib Delete $CATALINA_BASE/conf/logging.properties Start Tomcat (as a service) Expected Results According to the Guide I should have seen a tomcat.log file in my $CATALINA_BASE/logs folder. Actual Results No tomcat.log Saw three of the standard logs instead jakarta_service_20101231.log stderr_20101231.log stdout_20101231.log Question Shouldn't I have at least seen a tomcat.log file? Attempt 2 - Use default Tomcat logging (commons-logging) Reverted all the changes from the previous setup Modified $CATALINA_BASE/conf/logging.properties by doing the following: Adding a setting for my application in the handlers line: 5rails3.org.apache.juli.FileHandler Adding Handler specific properties 5rails3.org.apache.juli.FileHandler.level = FINE 5rails3.org.apache.juli.FileHandler.directory = ${catalina.base}/logs 5rails3.org.apache.juli.FileHandler.prefix = rails3. Adding Facility specific properties org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/rails3].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/rails3].handlers = 4host-manager.org.apache.juli.FileHandler Modified my web.xml by adding the following context parameter as per the Logging section of the jruby-rack readme (I also modified my warbler.rb accordingly, but I did opted to change the web.xml directly to test things faster). <context-param> <param-name>jruby.rack.logging</param-name> <param-value>commons_logging</param-value> </context-param> Restarted Tomcat Results A log file was created (rails3.log), however there was no log information in the file. Attempt 2A - Use Log4j with existing set up I decided to go Log4j another whirl with this new web.xml setting. Copied the log4j.jar into my WEB-INF/lib folder Created a log4j.properties file and put it into WEB-INF/classes log4j.rootLogger=INFO, R log4j.logger.javax.servlet=DEBUG log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=${catalina.base}/logs/rails3.log log4j.appender.R.MaxFileSize=5036KB log4j.appender.R.MaxBackupIndex=4 log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} [%t] %-5p %c %x - %m%n Restarted Tomcat Results Same as Attempt 2 NOTE: I used log4j.logger.javax.servlet=DEBUG because I read in the jruby-rack README that all logging output is automatically redirected to the javax.servlet.ServletContext#log method. So I though this would capture it. I was obviously wrong. Question Why didn't this work? Isn't Log4J using the commons_logging API? Attempt 3 - Tried out slf4j (WORKED) A bit uncertain as to why Attempt 2A didn't work, I thought to myself, maybe I can't use commons_logging for the jruby.rack.logging parameter because it's probably not using commons_logging API... (but I was still not sure). I saw slf4j as an option. I have never heard of it and by stroke of luck, I decided to look up what it is. After reading briefly about what it does, I thought it was good of a shot as any and decided to try it out following the instructions here. Continuing from the setup of Attempt 2A: Copied slf4j-api-1.6.1.jar and slf4j-simple-1.6.1.jar into my WEB-INF/lib folder I also copied slf4j-log4j12-1.6.1.jar into my WEB-INF/lib folder Restarted Tomcat And VIOLA! I now have logging information going into my rails3.log file. So the big question is: WTF? Even though logging seems to be working now, I'm really not sure if I did this right. So like I said earlier, I'm really looking for some validation more or less. I'd also appreciate any pointers/tips/advice if you have any. Thanks!

  • Search implementation dilemma: full text vs. plain SQL

    - by Ethan
    I have a MySQL/Rails app that needs search. Here's some info about the data: Users search within their own data only, so searches are narrowed down by user_id to begin with. Each user will have up to about five thousand records (they accumulate over time). I wrote out a typical user's records to a text file. The file size is 2.9 MB. Search has to cover two columns: title and body. title is a varchar(255) column. body is column type text. This will be lightly used. If I average a few searches per second that would be surprising. It's running an a 500 MB CentOS 5 VPS machine. I don't want relevance ranking or any kind of fuzziness. Searches should be for exact strings and reliably return all records containing the string. Simple date order -- newest to oldest. I'm using the InnoDB table type. I'm looking at plain SQL search (through the searchlogic gem) or full text search using Sphinx and the Thinking Sphinx gem. Sphinx is very fast and Thinking Sphinx is cool, but it adds complexity, a daemon to maintain, cron jobs to maintain the index. Can I get away with plain SQL search for a small scale app?

  • How to safely let users submit custom themes/plugins for a Rails app

    - by Brian Armstrong
    In my rails app I'd like to let users submit custom "themes" to display data in various ways. I think they can get the data in the view using API calls and I can create an authentication mechanism for this. Also an authenticated API to save data. So this is probably safe. But i'm struggling with the best way to let users upload/submit their own code for the theme. I want this to work sort of like Wordpress themes/plugins where people can upload the thing. But there are some security risks. For example, if I take the uploaded "theme" a user submits and put it in it's own directory somewhere inside the rails app, what are the risks of this? If the user inserts any rails executable code in their theme, even though it's the view they have full access at that point to all the models, everyone's data, etc. Even from other users. So that is not good. I need some way to let the uploaded themes exist in a sandbox of the rails app, but I haven't seen a good way to do this. Any ideas?

  • Rails: translations for table's column.

    - by Andrew
    In rails application I have two models: Food and Drink. Both food and drink have a name, which has to be stored in two languages. How do I better realize translations for theese tables? First solution I realized was to replace name column with name_en and name_ru. Another solution is to encode with YAML hash like { :en => 'eng', :ru => 'rus' } and store yaml as a name. What would you recommend, assuming content is not static? Maybe there's good article?

  • Rails - why would a model inside RAILS_ROOT/lib not be available in production mode?

    - by sa125
    Hi - I have a class located inside RAILS_ROOT/lib folder, which I use in one of my helpers, and it works great in development. When I switch to production, the application throws a NameError (uninitialized constant SomeHelper::SomeClass), and I have to load it manually in the helper: load "#{Rails.root}/lib/some_class.rb" module SomeHelper def some_method sc = SomeClass.new # blah end end I was under the impression that everything inside RAILS_ROOT/lib/* should be available all to the app - is there anything I need to configure to make this happen in prod mode? thanks.

  • Rails : fighting long http response times with ajax. Is it a good idea? Please, help with implementa

    - by baranov
    Hi, everybody! I've googled some tutorials, browsed some SO answers, and was unable to find a recipe for my problem. I'm writing a web site which is supposed to display almost realtime stock chart. Data is stored in constantly updating MySQL database, I wrote a find_by_sql query code which fetches all the data I need to get my chart drawn. Everything is ok, except performance - it takes from one second to one minute for different queries to fetch all the data from the database, this time includes necessary (My)SQL-server side calculations. This is simply unacceptable. I got the following idea: if the data is queried from the MySQL server one point a time instead of entire dataset, it takes only about 1-100ms to get an individual point. I imagine the data fetch process might be browser-driven. After the user presses the button in order to get a chart drawn, controller makes one request to the database and renders, say, a progress bar, say 1% ready. When the browser gets the response, it immediately makes an (ajax) request, and the server fetches the next piece of data and renders "2%". And so on, until all the data is ready and the server displays the requested chart. Could this be implemented in rails+js, is there a tutorial for solving a similar problem on the Web? I suppose if the thing is feasible at all, somebody should have already done this before. I have read several articles about ajax, I believe I do understand general principles, but never did nontrivial ajax programming myself. Thanks for your time!

  • How to make a small engine like Wolfram|Alpha?

    - by Koning WWWWWWWWWWWWWWWWWWWWWWW
    Lets say I have three models/tables: operating_systems, words, and programming_languages: # operating_systems name:string created_by:string family:string Windows Microsoft MS-DOS Mac OS X Apple UNIX Linux Linus Torvalds UNIX UNIX AT&T UNIX # words word:string defenitions:string window (serialized hash of defenitions) hello (serialized hash of defenitions) UNIX (serialized hash of defenitions) # programming_languages name:string created_by:string example_code:text C++ Bjarne Stroustrup #include <iostream> etc... HelloWorld Jeff Skeet h AnotherOne Jon Atwood imports 'SORULEZ.cs' etc... When a user searches hello, the system shows the defenitions of 'hello'. This is relatively easy to implement. However, when a user searches UNIX, the engine must choose: word or operating_system. Also, when a user searches windows (small letter 'w'), the engine chooses word, but should also show Assuming 'windows' is a word. Use as an <a href="etc..">operating system</a> instead. Can anyone point me in the right direction with parsing and choosing the topic of the search query? Thanks. Note: it doesn't need to be able to perform calculations as WA can do.

  • How to call a Thor task multiple times?

    - by deepak
    Thor like Rake (and Make) has task management. If I call a task multiple times, it will effectively call the task only once. How can I call a task multiple times? I tried modifying the @_invocations hash, but that did not work: require 'csv' require './config/environment' class MisReport < Thor desc "all", "generate mysql and postgres mis" def all generate("pg_mis_report", "pg") generate("mysql_mis_report", "mysql") end desc "generate", "generate mis report" def generate(file_name = "mis_report_#{Time.now.to_s(:number)}", connection = "postgres") if connection == "pg" puts "== postgres database" ActiveRecord::Base.establish_connection :development_mysql else puts "== mysql database" ActiveRecord::Base.establish_connection :development end # generate MIS puts puts "mis file is at: #{file_path}" end end

In the Fruit model I have: set_inheritance_column :taste_type In my migration to add STI I have: class AddSTI < ActiveRecord::Migration def self.up add_column :fruits, :taste_type, :string, :limit => 100, :null => false Fruit.reset_column_information Fruit.find_by_id(1).update_attributes({:taste_type => 'Sour'}) end def self.down remove_column :fruits, :taste_type end end When I run the migration, I get the following error: Mysql::Error: Column 'taste_type' cannot be null: ... Any idea what's going? I can get the migration to run if I comment the set_inheritance_column in the Fruit model, then uncomment it after I run the migration. Obviously, I don't want to do this, however.

  • How do I programmatically convert mp3 to an itunes-playable aac/m4a file?

    - by kwork
    I've been looking for a way to convert an mp3 to aac programmatically or via the command line with no luck. Ideally, I'd have a snippet of code that I could call from my rails app that converts an mp3 to an aac. I installed ffmpeg and libfaac and was able to create an aac file with the following command: ffmpeg -i test.mp3 -acodec libfaac -ab 163840 dest.aac When i change the output file's name to dest.m4a, it doesn't play in iTunes. Thanks!

  • Saving a record in Authlogic table

    - by denniss
    I am using authlogic to do my authentication. The current model that serves as the authentication model is the user model. I want to add a "belongs to" relationship to user which means that I need a foreign key in the user table. Say the foreign key is called car_id in the user's model. However, for some reason, when I do u = User.find(1) u.car_id = 1 u.save! I get ActiveRecord::RecordInvalid: Validation failed: Password can't be blank My guess is that this has something to do with authlogic. I do not have validation on password on the user's model. This is the migration for the user's table. def self.up create_table :users do |t| t.string :email t.string :first_name t.string :last_name t.string :crypted_password t.string :password_salt t.string :persistence_token t.string :single_access_token t.string :perishable_token t.integer :login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.integer :failed_login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.datetime :last_request_at # optional, see Authlogic::Session::MagicColumns t.datetime :current_login_at # optional, see Authlogic::Session::MagicColumns t.datetime :last_login_at # optional, see Authlogic::Session::MagicColumns t.string :current_login_ip # optional, see Authlogic::Session::MagicColumns t.string :last_login_ip # optional, see Authlogic::Session::MagicColumns t.timestamps end end And later I added the car_id column to it. def self.up add_column :users, :user_id, :integer end Is there anyway for me to turn off this validation?

  • How to recursive rake? -- or suitable alternatives

    - by TerryP
    I want my projects top level Rakefile to build things using rakefiles deeper in the tree; i.e. the top level rakefile says how to build the project (big picture) and the lower level ones build a specific module (local picture). There is of course a shared set of configuration for the minute details of doing that whenever it can be shared between tasks: so it is mostly about keeping the descriptions of what needs building, as close to the sources being built. E.g. /Source/Module/code.foo and cie should be built using the instructions in /Source/Module/Rakefile; and /Rakefile understands the dependencies between modules. I don't care if it uses multiple rake processes (ala recursive make), or just creates separate build environments. Either way it should be self-containable enough to be processed by a queue: so that non-dependent modules could be built simultaneously. The problem is, how the heck do you actually do something like that with Rake!? I haven't been able to find anything meaningful on the Internet, nor in the documentation. I tried creating a new Rake::Application object and setting it up, but whatever methods I try invoking, only exceptions or "Don't know how to build task ':default'" errors get thrown. (Yes, all rakefiles have a :default). Obviously one could just execute 'rake' in a sub directory for a :modulename task, but that would ditch the options given to the top level; e.g. think of $(MAKE) and $(MAKEFLAGS). Anyone have a clue on how to properly do something like a recursive rake?

  • Avoiding Duplicate Data in DB (for use with Rails)

    - by ants
    I have five tables that I am trying to get to work nicely together but may need some help. I have three main tables: accounts members and roles. With two join tables account_members and account_member_roles. The accounts and members table are joined by account_members (fk account_id and member_id) table. The other 2 tables are the problem (roles and account_member_roles). A member of an account can have more than one role and I have the account_member_roles (fk account_member_id and role_id) table joining the account_members join table and the roles table. That seems logical but can you have a relationship with a join table? What I'd like to be able to do is when creaeting an account, for instance, I would like @account.save to include the roles and update the account_member_roles table neatly ..... but through the account_members join table. I've tried ..... accept_nested_attributes_for :members, :account_member_roles in the account.rb but I get ..... ActiveRecord::HasManyThroughCantAssociateThroughHasManyReflection (Cannot modify association 'Account#account_member_roles' because the source reflection class 'AccountMemberRole' is associated to 'AccountMember' via :has_many.) upon trying to save a record. Any advice on how I should approach this? CIA -ants
