  • tinymce in ajax call - how to get contents

    - by haries
    this is what I have in my view: <% form_remote_tag :url => { :controller => 'comments', :action => "create", :post_id => "#{@post.id}"}, :html => {:id => 'comment_form' }, :before => "tinyMCE.triggerSave(true,true);" do %> <%= label_tag 'Comment' %><br/> <%= text_area_tag :comment_body, nil,:rows => 10, :cols => 100 %><br/> <p style="margin-top: 10px;"> <%= submit_tag 'Add',:id => 'btnCommentSave' %> </p> <% end %> Tinymce editor is displayed properly. In my controller: how to get the contents of the text area? I am expecting the contents in params[:comment_body] and I am not seeing it? I tried doing this also, $('#btnCommentSave').click( function(){ tinyMCE.triggerSave(true,true); $('#comment_form').submit(); }); What am I missing? Thanks

  • Schema for storing "binary" values, such as Male/Female, in a database

    - by latentflip
    Intro I am trying to decide how best to set up my database schema for a (Rails) model. I have a model related to money which indicates whether the value is an income (positive cash value) or an expense (negative cash value). I would like separate column(s) to indicate whether it is an income or an expense, rather than relying on whether the value stored is positive or negative. Question: How would you store these values, and why? Have a single column, say Income, and store 1 if it's an income, 0 if it's an expense, null if not known. Have two columns, Income and Expense, setting their values to 1 or 0 as appropriate. Something else? I figure the question is similar to storing a person's gender in a database (ignoring aliens/transgender/etc) hence my title. My thoughts so far Lookup might be easier with a single column, but there is a risk of mistaking 0 (false, expense) for null (unknown). Having seperate columns might be more difficult to maintain (what happens if we end up with a 1 in both columns? Maybe it's not that big a deal which way I go, but it would be great to have any concerns/thoughts raised before I get too far down the line and have to change my code-base because I missed something that should have been obvious! Thanks, Philip

    - by Jiang
    Hi all, I tried to use Devise 1.0.6 over Rails 2.3. I followed the installation instructions and the user can successfully sign up. However, when I use the registered user account to sign in, the password field is cleared up and nothing happened. Could anyone give me some ideas? Thanks in advance.

    - by ramonrails
    I am trying to achieve this. Any hints? A project has many users through join model A user has many projects through join model Admin class inherits User class. It also has some Admin specific stuff. Admin like inheritance for Supervisor and Operator Project has one Admin, One supervisor and many operators.

  • uninitialized constant MysqlCompat::MysqlRes (using mms2r gem)

    - by William
    Hi, moved a rails app of mine onto a new server and had to install a few gem dependencies. However, after installing the mysql gem I get the error, uninitialized constant MysqlCompat::MysqlRes, whenever I try to run a rake command that involves the mysql database. It seems I only get this error when I require the mms2r gem. Has anyone ever heard of this? I'm running mysql 2.8.1 gem.

  • gsub! Is modifying unspecified strings

    - by user335729
    I'm extracting some information from an XML file, and I want to perform some modifications on the data while keeping a copy of the original in a variable "origFile". This is what I have: require "rexml/document" include REXML doc = Document.new File.new(thePath) root = doc.root array = [] root.elements.each("dict/string") {|element| array << element} origFile = [] root.elements.each("dict"){|i| origFile << i} theBody = array[6][0].to_s theBody.gsub!(/\&lt;!-- more --\&gt;/, "----------Read More----------") The problem is that after I perform gsub! on theBody, origFile also has the modification. I don't understand why this would be or how to fix it. I would really appreciate your help.

  • Need a push in the right direction, to write my first functional test in Rails

    - by Jason
    I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword true is simply returned, otherwise the keyword false is returned - its in only value returned & not contained in any <div>, <span> or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful!

  • Database locking: ActiveRecord + Heroku

    - by JP
    I'm building a Sinatra based app for deployment on Heroku. You can imagine it like a standard URL shortener but where old shortcodes expire and become available for new URLs (I realise this is a silly concept but its easier to explain this way). I'm representing the shortcode in my database as an integer and redefining its reader to give a nice short and unique string from the integer. As some rows will be deleted, I've written code that goes thru all the shortcode integers and picks the first free one to use just before_save. Unfortunately I can make my code create two rows with identical shortcode integers if I run two instances very quickly one after another, which is obviously no good! How should I implement a locking system so that I can quickly save my record with a unique shortcode integer? Here's what I have so far: Chars = ('a'..'z').to_a + ('A'..'Z').to_a + ('0'..'9').to_a CharLength = Chars.length class Shorts < ActiveRecord::Base before_save :gen_shortcode after_save :done_shortcode def shortcode i = read_attribute(:shortcode).to_i return '0' if i == 0 s = '' while i > 0 s << Chars[i.modulo(CharLength)] i /= 62 end s end private def gen_shortcode shortcode = 0 self.class.find(:all,:order=>"shortcode ASC").each do |s| if s.read_attribute(:shortcode).to_i != shortcode # Begin locking? break end shortcode += 1 end write_attribute(:shortcode,shortcode) end def done_shortcode # End Locking? end end

  • jruby/activerecord-jdbc/tomcat/DB2 ready for enterprise?

    - by arkadiy
    I am trying to introduce RoR to my company and I have two ways of doing so in my mind: (1) rails/ibm_db2/passenger/DB2 - which is my preferable way but it is not really supported by company's infrastructure. (2) jruby/activerecord-jdbc/tomcat/DB2 - probably easier way to migrate relying on current infrastructure and java libs IF I have a proof this is an enterprise ready technology. Does anyone know if there is any prof that jruby/aciverecord-jdbc-adapter/DB2/tomcat is mature enough for production? Are there any problems I should know about during Development/Deployment/Runtime? My webapp is for a company intranet, around 200~400 active users.

  • ActiveRecord Validations for Models with has_many, belongs_to associations and STI

    - by keruilin
    I have four models: User Award Badge GameWeek The associations are as follows: User has many awards. Award belongs to user. Badge has many awards. Award belongs to badge. User has many game_weeks. GameWeek belongs to user. GameWeek has many awards. Award belongs to game_week. Thus, user_id, badge_id and game_week_id are foreign keys in awards table. Badge implements an STI model. Let's just say it has the following subclasses: BadgeA and BadgeB. Some rules to note: The game_week_id fk can be nil for BadgeA, but can't be nil for BadgeB. Here are my questions: For BadgeA, how do I write a validation that it can only be awarded one time? That is, the user can't have more than one -- ever. For BadgeB, how do I write a validation that it can only be awarded one time per game week?

  • globalize2 with xml/json support

    - by Philipp Bolliger
    I'm implementing a distributed application, server with rails and mobile clients in objective c (iPhone). To enable internationalization, I use the rails plugin 'globalize2' by joshmh. However, it turned out that this plugin does not translate attributes when calling to_xml or to_json on an ActiveRecord. Does anyone know of a workaround / patch? Do you have any ideas how to fix this, where to alter globalize2? Using: Rails 2.3.5 globalize2: commit from 2010-01-11

  • Rails authorization plugins

    - by jacklin
    We are evaluating plugins for Authorization in Rails. The two at the top of our list are cancan and declarative_authorization. I would like to get some feedback from anyone currently using either of these plugins. The problem we are going to face with any authorization plugin is that we have a database per customer model and will need to modify the plugin to work within that model. Because of this fact I'm interested in hearing from anyone who has had to tweak the plugins at all as well. I'm just starting to look around at the code. It seems like cancan might be a little easier to customize. Any thoughts?

  • Is there something similar to 'rake routes' in django?

    - by The MYYN
    In rails, on can show the active routes with rake (http://guides.rubyonrails.org/routing.html): $ rake routes users GET /users {:controller=>"users", :action=>"index"} formatted_users GET /users.:format {:controller=>"users", :action=>"index"} POST /users {:controller=>"users", :action=>"create"} POST /users.:format {:controller=>"users", :action=>"create"} Is there a similar tool/command for django showing the e.g. the URL pattern, the name of the pattern (if any) and the associated function in the views?

  • Using ActiveRecord caching library in Heroku

    - by zetarun
    Hi all, I'm studying how to use caching in Heroku for my Rails app. HTTP cache powered by Varnish is superb and I'll use it in all pages without user info but I also want to use a kind of ActiveRecord caching with Memcached using "high livel" plugins such as cache_fu or cache-money...but it seems that Heroku supports only the memcached gem (http://docs.heroku.com/memcache) and it's a very low level Memcachad API... Do you have any other solutions? Thx.

  • Rails is not passing the "commit" button parameter

    - by Wayne M
    Reinstalling a Rails app on a new server. Part of the app can fork in one of two directions based on the button the user selects. This part isn't working, and when I look at the log I see the values that I gave the form, execept for the commit portion of the params hash. This seems to be why the app isn't working as expected (since there's nothing in params[:commit], but I have no idea why commit would not be passed in; the request is definitely a POST request, and all of the other parameters are there.

  • Online job-searching is tedious. Help me automate it.

    - by ehsanul
    Many job sites have broken searches that don't let you narrow down jobs by experience level. Even when they do, it's usually wrong. This requires you to wade through hundreds of postings that you can't apply for before finding a relevant one, quite tedious. Since I'd rather focus on writing cover letters etc., I want to write a program to look through a large number of postings, and save the URLs of just those jobs that don't require years of experience. I don't require help writing the scraper to get the html bodies of possibly relevant job posts. The issue is accurately detecting the level of experience required for the job. This should not be too difficult as job posts are usually very explicit about this ("must have 5 years experience in..."), but there may be some issues with overly simple solutions. In my case, I'm looking for entry-level positions. Often they don't say "entry-level", but inclusion of the words probably means the job should be saved. Next, I can safely exclude a job the says it requires "5 years" of experience in whatever, so a regex like /\d\syears/ seems reasonable to exclude jobs. But then, I realized some jobs say they'll take 0-2 years of experience, matches the exclusion regex but is clearly a job I want to take a look at. Hmmm, I can handle that with another regex. But some say "less than 2 years" or "fewer than 2 years". Can handle that too, but it makes me wonder what other patterns I'm not thinking of, and possibly excluding many jobs. That's what brings me here, to find a better way to do this than regexes, if there is one. I'd like to minimize the false negative rate and save all the jobs that seem like they might not require many years of experience. Does excluding anything that matches /[3-9]\syears|1\d\syears/ seem reasonable? Or is there a better way? Training a bayesian filter maybe?

  • How do I do a count on that meet a specific condition, dependent on several has_many relationships i

    - by Angela
    I have a Model Campaign. A Campaign has many Events. Each Event has an attribute :days. A Campaign also has_many Contacts. Each Contact as a :date_entered attribute. The from_today(contact,event) method returns a number, which is the number of days from the contact's :date_entered till today minus the event's :days. In other words, a positive number shows the number of days from today till the :days of the event is elapsed. If it is negative, if means that the number of days that has elapsed since the :date_entered is greater than the :days attribute of an event. In other words, the event is overdue. What I would like to be able to do is do campaign.overdue and this would result in a total number of contacts that have an overdue event. It shouldn't count multiple events for a single contact, just one contact. How do I do that? It seems like I would need to cycle through all the events for every contact and keep a counter but I'm assuming that there is a better way.

  • Refactoring multiple if statements for user authentication with subdomains

    - by go minimal
    I'm building a typical web app where once a user signs up they access the app through their own subdomain (company.myapp.com). The "checking what kind of user if any is logged in" piece is starting to get very hairy and it obviously needs to be well-written because its run so often so I was wondering how you guys would re-factor this stuff. Here are the different states: A user must be logged in, the user must not have a company name, and the sub-domain must be blank A user must be logged in, the user must have a company name, that company name must match the current sub-domain A user must be logged in, the user must have a company name, that company name must match the current sub-domain, and the user's is_admin boolean is true if !session[:user_id].nil? @user = User.find(session[:user_id]) if @user.company.nil? && request.subdomains.first.nil? return "state1" elsif [email protected]? if @user.company.downcase == request.subdomains.first.downcase && [email protected]_admin return "state2" elsif @user.company.downcase == request.subdomains.first.downcase && @user.is_admin return "state3" end end end

  • 1-st level routes for multiple resources in Rails

    - by Leonid Shevtsov
    I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).

    How rails applications actually work? Let's say we have nginx + passenger + Ubuntu, so my questions are: What is nginx actually doing? How does it transfer requests to the rails app? what is passenger responsible for? And what is rack? How actually rails app can work just on webrick without apache? Please dont give me answers like "nginx processes the requests"; I need something more, or may be you know the source where I can read about this.
