  • how to change locale in URL using Routing Filter gem Rails I18n application?

    - by Zack Xu
    I installed and set up routing-filter as described on the gem documentation page. https://github.com/svenfuchs/routing-filter It works for the default locale. For example, if I set up my default locale as :en,the site is in English, and if I set my default locale as :zh, the site is in Chinese. www.site.com/zh/home (the default locale path /en is automatically added to the URL) But how can I make my site support BOTH languages? when the default locale is :zh, I tried to change the URL by substituting the "zh" with "en" but the page is still in Chinese, not English. Is this something not supported by the routing-filter gem? If not, is there some other gem I can use? Or have I not set up the routing-filter gem properly? Thanks!

  • Suggestions on how to track tag count for a particular object

    - by Robin Fisher
    Hi, I'm looking for suggestions on how to track the number of tags associated with a particular object in Rails. I'm using acts_as_taggable_on and it's working fine. What I would like to be able to do is search for all objects that have no tags, preferably through a scope i.e. Object.untagged.all My first thought was to use an after_save callback to update an attribute called "taggings_count" in my model: def update_taggings_count self.taggings_count = self.tag_list.size self.save end Unfortunately, this does the obvious thing of putting me in an infinite loop. I need to use an after_save callback because the tag_list is not updated until the main object is saved. Would appreciate any suggestions as I'm on the verge of rolling my own tagging system. Regards Robin

  • How to use form_tag to update params

    - by Tryskele
    I have been struggling with a problem in Rails for a couple of days and still could not find the solution. Could you help me with that? Problem: I have a search box that puts a :search_string entry in the params structure. I use a form_tag for that and it works fine. <% form_tag :controller=> 'items', :action => 'find' do %> <%= text_field_tag :search_string, params[:search_string] %> <% end %> The problem is when I want to add and update other params key-value (in another view), for instance :start_date, to filter the search_string result. Here is the code snipped that I use in the view: <% form_tag :controller=> "items", :action => "find", :params => params do %> <%= hidden_field_tag :date_start, '2010-04-01' %> <%= submit_tag 'April' %> <% end %> <% form_tag :controller=> "items", :action => "find", :params => params do %> <%= hidden_field_tag :date_start, '2010-03-01' %> <%= submit_tag 'March' %> <% end %> When I first click on "April" submit button, then the params is correctly passed to the controller (i.e. there is a params[:start_date]='April'). However when I try to click "March" button afterwards, the params[:start_date] is not updated. I definitely think this is a stupid newbie mistake, but I cannot figure out how to properly use the form_tag. Could you tell me if I am doing something work? Otherwise, could you advise me which is the best way to update the params using form_tag's ? Thank you very much in advance. Miquel

  • how do i set up a load balanced Rails web server using mongrel, lighttpd and iis on windows 2003

    - by user91519
    I understand that this is not the perfect environment for doing this but please stick with me and help if you can... The set up I want to achieve is to have my rails application running on a windows 2003 server, using a pack of mongrels with lighttpd acting as the load balancer and IIS in front of it all passing client requests to lighttpd. first of all i've followed these instructions: deploying to iis on windows And I've managed to get the application to run, BUT if the client clicks on a link button the app bombs out with a 500 server error. If I just run against one of the mongrel servers, the the app behaves ok, so I think its lightpd. Its almost as if the lighttpd gets confused with multiple GET requests (i.e. multiple clicks) and bombs out. Any help on why i'm getting 500 errors would be helpful, thanks.

  • Incorrect error

    - by jspooner
    If you assign an invalid date (like December 39th) to a datetime column ActiveRecord returns a "can't be blank" error when is should probably return an error like "Not a valid date" My question. Is this expected rails behavior, a bug or, something that I could patch? class ExerciseLog < ActiveRecord::Base validates_presence_of :scheduled_datetime end Fire up the console. e = Log.new # lets set a date for Dec 39th which obviously doesn't exist e.scheduled_datetime = "2010-12-39" e.save => false # this is the confusing message since our form did post a valid date e.errors.on(:scheduled_datetime) => "can't be blank" e.scheduled_datetime = "2010-12-30" e.save => true I discovered this issue when I accidentally transposed the month and day values. btw This is in Rails 2.3.5

  • Getting the first of a GROUP BY clause in SQL

    - by Michael Bleigh
    I'm trying to implement single-column regionalization for a Rails application and I'm running into some major headaches with a complex SQL need. For this system, a region can be represented by a country code (e.g. us) a continent code that is uppercase (e.g. NA) or it can be NULL indicating the "default" information. I need to group these items by some relevant information such as a foreign key (we'll call it external_id). Given a country and its continent, I need to be able to select only the most specific region available. So if records exist with the country code, I select them. If, not I want a records with the continent code. If not that, I want records with a NULL code so I can receive the default values. So far I've figured that I may be able to use a generated CASE statement to get an arbitrary sort order. Something like this: SELECT *, CASE region WHEN 'us' THEN 1 WHEN 'NA' THEN 2 ELSE 3 END AS region_sort FROM my_table WHERE region IN ('us','NA') OR region IS NULL GROUP BY external_id ORDER BY region_sort The problem is that without an aggregate function the actual data returned by the GROUP BY for a given row seems to be untameable. How can I massage this query to make it return only the first record of the region_sort ordered groups?

  • Get pixel color with Rails or anything else

    - by ulf
    I'd like to build a webapp in Rails in which I'd like to determine every pixel's color of a given image (JPEG). Is there any possibility to do that with Rails or JavaScript? The goal is to write an algorithm which determines the "middle color" of the image and uses it for background color of the site. Any suggestion would be appreciated.

  • Nginx: check content-length before file upload takes place

    - by robw
    I'm trying to prevent users from uploading (accidentally or maliciously) very large files to my website. I have nginx max_client_body_size set to 4M, but if a file larger than this is uploaded, then it uploads the entire file before returning 413 (entity too large). I want to make nginx check the Content-Length header, so that it rejects the request before it's uploaded. Alternatively, a Rails solution would also be acceptable. Any help appreciated.

  • Rails 3: habtm migration, primary key issue

    - by Brian Wigginton
    I'm trying to setup a migration file for a habtm relationship, however when I run the migration I'm getting the following error: Primary key is not allowed in a has_and_belongs_to_many join table (parts_vehicles). Here is my migration file (20110111035950_create_parts_vehicles.rb): class CreatePartsVehiclesJoinTable < ActiveRecord::Migration def self.up create_table :parts_vehicles, :id => false do |t| t.integer :part_id t.integer :vehicle_id end end def self.down drop_table :parts_vehicles end end The documentation example states to use :id => false to disable a primary key from being generated, but I'm still getting the error.

  • PostgreSQL + Rails citext

    - by glebm
    I am trying to move to heroku which uses PostgreSQL 8.4 which has a citext column type which is nice since the app was written for MySQL. Is there any way to use :citext with rails (so that if the migrations are run on MySQL the citext would just use string/text? I found this ticket, but it seems like it isn't going to be a part of rails for a while: https://rails.lighthouseapp.com/projects/8994/tickets/3174-add-support-for-postgresql-citext-column-type

  • Rails has_and_belongs_to_many join across 3 tables

    - by Birdman
    I have a three models: listing, category, and site. There is a many to many relationship between listing and site and there is a many to many relationship between listing and category. A listing thus belongs to one or more sites and one or more categories (a listing can appear on multiple sites and multiple categories). Given a site id and a category id, I want a set of all the listings. I understand how to get the listings from a site id (listings = site.listings) and how to get the listings from a category id (listings = category.listings), but how do I get the triple join of the set of listings from both a site id and category id? The sql would look something like (sit_id and cat_id are input): select l.name from listings l, categories_listings cl, listings_sites, ls where cl.category_id = cat_id and ls.site_id = sit_id and cl.listing_id = l.id and ls.listing_id = l.id Thanks in advance

  • I want to use the fleximage gem and s3 for storage, but don't want dev/qa/test env's to use s3

    - by Kevin Bedell
    I have a rails app that I'm going to host on engineyard and want to store image files on s3. But I don't know if I want all developer machines to beusing s3 for storage of all our test and dev images. Maybe it's not an issue -- but it seems like a waste to have everyone storing all our images in s3. I've heard of some ppl who store images on s3 'hacking' dev environments to store images locally on the file system -- and then using s3 in prod only. What are other people doing?

  • Hashes or tokens for "remember me" cookies?

    - by Emanuil Rusev
    When it comes to remember me cookies, there are 2 distinct approaches: Hashes The remember me cookie stores a string that can identify the user (i.e. user ID) and a string that can prove that the identified user is the one it pretends to be - usually a hash based on the user password. Tokens The remember me cookie stores a random (meaningless), yet unique string that corresponds with with a record in a tokens table, that stores a user ID. Which approach is more secure and what are its disadvantages?

  • Rails3 and safe nl2br !

    - by arkannia
    Hi, I have a system for the users to be able to post comments. The comments are grasped into a textarea. My problem is to format the comments with br tag to replace \n In fact, i could do something like that s.gsub(/\n/, '<br />') But the xss protection including in rails escapes br tags. So i could do this s.gsub(/\n/, '<br />').html_safe But then, all the tags are accepted even script.... causing a big security problem So my question is : how to format text with br safely ? Thanks EDIT: For now, i have add this def sanitaze self.gsub(/(<.*?>)/, '') end def nl2br self.sanitaze.gsub(/\n/, '<br />').html_safe end
