• Rails architecture questions

  - by justinbach

  I'm building a Rails site that, among other things, allows users to build their own recipe repository. Recipes are entered either manually or via a link to another site (think epicurious, cooks.com, etc). I'm writing scripts that will scrape a recipe from these sites given a link from a user, and so far (legal issues notwithstanding) that part isn't giving me any trouble. However, I'm not sure where to put the code that I'm writing for these scraper scripts. My first thought was to put it in the recipes model, but it seems a bit too involved to go there; would a library or a helper be more appropriate? Also, as I mentioned, I'm building several different scrapers for different food websites. It seems to me that the elegant way to do this would be to define an interface (or abstract base class) that determines a set of methods for constructing a recipe object given a link, but I'm not sure what the best approach would be here, either. How might I build out these OO relationships, and where should the code go?

• Does a rails production.log store indefinitely?

  - by Trip

  If it doesn't, what's the half-life of it? It it does, where can find that information? On my server I found a few logs for each of my releases. But they only date back a few days. Specifically, I am looking for emails that were sent while my mail server was down two weeks ago.

• rails controller defaults to respond with application/xml in production

  - by Dave Paroulek

  I have a standard contacts_controller.rb with index action that responds as follows: respond_to do |format| format.html format.xml { render :xml => @contacts } end In development, it works as intended: when I browse to http://localhost:3000/contacts, I get an html response. But, when I start the app using capistrano on a remote Ubuntu server and browse to the same url, I get an xml response. If I go to http://remote_host:8000/contacts.html, then I see the html response. If I comment out the format.xml { render :xml => @contacts }, then I see the desired html response. Pretty sure I'm missing something subtle about difference between Rails development and production modes. Any ideas about what I'm overlooking? Thanks, - Dave

• can rails send data to browser chunk by chunk?

  - by Nik

  Hello all, I have a very large dataset (100,000) to be display, but any browser I tried that on including chrome 5 dev, it make them choke for dozens of seconds (win7 64bit, 4gb, 256gb ssd, c2duo 2.4ghertz). I did a little experiment by some_controller.rb def show @data = (1..100000).to_a end show.html.erb <% @data.each do |d| % <%= d.to_s % <% end% as simple as that it chokes the browsers. I know browsers were never built for this, so I thought to let the data come in chunk by chunk, I guess 2000 per chunk is reasonable, but I wouldn't want to make 50 requests each time this view is called, any ideas? It doesn't have to be chunk by chunk if it can be sent all at once. Best,

• Rack URL Mapping

  - by Puru puru rin..

  Hi, I am trying to write two kind of Rack routes. Rack allow us to write such routes like so: app = Rack::URLMap.new('/test' => SimpleAdapter.new, '/files' => Rack::File.new('.')) In my case, I would like to handle those routes: "/" or "index" "/*" in order to match any other routes So I had trying this: app = Rack::URLMap.new('/index' => SimpleAdapter.new, '/' => Rack::File.new('./public')) This works well, but... I don't know how to add '/' path (as alternative of '/index' path). The path '/*' is not interpreted as a wildcard, according to my tests. Do you know how I could do? Thanks

• Searching pgadmin db and grabbing information?

  - by Bootstrotter

  I'm currently trying to write a script in RoR to go into my PGAdmin database and look at a list of users, THEN ignore users that have an image path but look at users who don't have one and then upload a link of a generic photo into their row. My database looks Something like this: id integer | name | email | image path | 12 Bob [email protected] www.faces.org 81 Sally [email protected] 114 Mark [email protected] www.faces.org How would I start grabbing those users, I only have 103 users right now, but I also need to think about scaling for the future. Here is a starting point. I know this is kind of vague but really all I need is just a starting point. to get into it. Thanks for the information. require 'sqlite3' db = SQlite3 users = users.find([1, 103]) Any help would be great.

• load search results into a div jquery and rails

  - by odpogn

  In my rails app I have a search bar where users can search other users. Currently when a User submits the search from, they're redirected to a "results" page. I want to load those results in a div on the same page.. I was able to do this with my websites navigation links, but I'm pretty new to jQuery and rails and can't figure this one out... my jQuery corresponding to my navigation links: $(function() { $('#links a').live('click', function() { $('#pages').load(this.href).fadeIn('slow'); return false; }); }); my attempt to do the same with my search function... $(function() { $('#search').submit(function() { $('#pages').load(this.href).fadeIn('slow'); }); }); any help would be much appreciated~ along with some useful jQuery tutorials for a newbie!!

• Is there a better acts_as_commentable for Rails?

  - by levi rosol

  Here's what I'm looking to do. I have a site where I want the user to be able to leave comments on various Models. acts_as_commentable is the obvious starting point for this, but I'm curious if there is a gem / plug-in with a more robust feature-set. For example: Pre-built partial(s) (w/ or w/o Twitter / FB buttons) Partial(s) that utilize jQuery Twitter and / or FB tunnels (push to the users twitter / FB when they comment) Pre-built mechanism for pushing other users comments to users viewing that Model I can see how some of this functionality could be app specific, however, a generic implementation seems like it would be useful. I'm curious if something like this exists or not.

• What is the best way to do scoped finds based on access control rules in Rails?

  - by Rafael Szuminski

  Hi I need to find an elegant solution to scoped finds based on access control rules. Essentially I have the following setup: Users Customers AccessControl - Defines which user has access to another users data Users need to be able to access not just their own customers but also shared customers of other users. Obviously something like a simple association will not work: has_many :customers and neither will this: has_many :customers, :conditions => 'user_id in (1,2,3,4,5)' because the association uses with_scope and the added condition is an AND condition not an OR condition. I also tried overriding the find and method_missing methods with the association extension like this: has_many :customers do def find(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end def method_missing(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end end but the issue is that I don't have access to the user object / parent object inside the extension methods and it just does not work as planned. I also tried default_scope but as posted here before you can't pass a block to a default scope. Anyhow, I know that data segmentation and data access controls have been done before using rails and am wondering if somebody found an elegant way to do it. UPDATE: The AccessControl table has the following layout user_id shared_user_id The customer table has this structure: id account_id user_id first_name last_name Assuming the the following data would be in the AccessControl table: 1 1 1 3 1 4 2 2 2 13 and so on... And the account_id for user 1 is 13 I need to be able to retrieve customers that can be best described with the following sql statement: select * from customers where (account_id = 13 and user_id = null) or (user_id in (1,3,4))

• How to create a user customizable database (like Zoho creator) in Rails?

  - by martjno

  I'm learning Rails, and the target of my experiments is to realize something similar to Zoho Creator, Flexlist or Mytaskhelper, i.e. an app where the user can create his own database schema and views. What's the best strategy to pursue this? I saw something about the Entity-Attribute-Value but I'm not sure whether it's the best strategy or if there is some support in Rails for it. If there was any tutorial in Rails about a similar project it would be great. Probably it's not the easiest star for learning a new language and framework, but it would be something I really plan to do since a long time.

• Is there a variable in Rails that equates to the template that is being rendered?

  - by Sean Ahrens

  I can do request.path_parameters['controller'] and request.path_parameters['action'], but is there anything like request.path_parameters['template'] so I can discern which template file (such as index.html.erb) is being rendered? I'm writing a method that automatically sets the body id to the template being rendered, for easy css manipulation: class ApplicationController < ActionController::Base ... after_filter :define_body_selector ... def define_body_selector # sets @body_id to the name of the template that will be rendered # ie. if users/index.html.erb was just rendered, @body_id gets set to "index" @body_id = ??? end ...

• Rails: getting logic to run at end of request, regardless of filter chain aborts?

  - by JSW

  Is there a reliable mechanism discussed in rails documentation for calling a function at the end of the request, regardless of filter chain aborts? It's not after filters, because after filters don't get called if any prior filter redirected or rendered. For context, I'm trying to put some structured profiling/reporting information into the app log at the end of every request. This information is collected throughought the request lifetime via instance variables wrapped in custom controller accessors, and dumped at the end in a JSON blob for use by a post-processing script. My end goal is to generate reports about my application's logical query distribution (things that depend on controller logic, not just request URIs and parameters), performance profile (time spent in specific DB queries or blocked on webservices), failure rates (including invalid incoming requests that get rejected by before_filter validation rules), and a slew of other things that cannot really be parsed from the basic information in the application and apache logs. At a higher level, is there a different "rails way" that solves my app profiling goal?

• Rails time zones

  - by Bob

  I'm calling an external web service API that returns a timezone as listed in the Olson timezones database (e.g. "America/New_York"). However some of the values the API returned are "US/Pacific", "US/Eastern" and apparently don't match any of the Olson timezones in Rails 2.3.2. Can anyone shed some light on this? Thanks in advance for your help.

• How does 37signals job preview functionality work?

  - by slythic

  Hi all, I'm interested in getting a preview functionality working similar to how the 37signals job site does: http://jobs.37signals.com. Below are some screen shots of how it works. Step 1. Create your ad http://cl.ly/dfc4761b015c7f43c8ab (URL /jobs/new) Step 2. Preview your ad http://cl.ly/9c4b4041cfea83d8569e (URL /jobs/new/preview) Step 3. Publish your ad http://cl.ly/a58284d90fd380d2c26b (URL /listings/new/purchase?token=5198) So assuming you have Post model where Step 1 usually takes place in the new/create view/actions, how should one continue to Step 2 Preview and then after previewing, proceeding to the Step 3 publishing the post/ad? Do they actually save the ad/post in the database before continuing to Step 2 (Preview) but set a flag (like a boolean field called preview set to true)? It looks like they set a token paramater but I'm not sure what it's used for) I'm interested in this because it seems to go against the CRUD/REST and I thought it would be good to know how it worked. Thanks!
