  • Rails view - user enters minutes, we save seconds?

    - by sscirrus
    Hi everyone, I have a simple text_field in my form where a user enters a time in minutes, i.e. 60. How can I multiply that number by 60 before saving the form, such that the database stores the number in seconds? Then, how do I reverse that and show the field in minutes on another view? Thank you!

  • Is there a way to have three way habtm associations in rails / activerecord?

    - by txwikinger
    Often three (or more) way associations are needed for habtm associations. For instance a permission model with roles. A particular area of functionality has many users which can access many areas. The permissions on the area are setup via roles (habtm) The user/roles association is also habtm The permissions (read, write, delete, etc) are habtm towards roles. How would that be best done with rails/activerecord?

  • MIgrations and Rspec

    - by pablorc
    Hi, I'm developing a Rails application with Rspec for unit testing. Weeks ago, Rspec used to migrate the database to the last version automatically when executing 'rake spec', but now it doesn't do it automatically, I have to implement everything for myself. This happens in test environment, because my development data doesn't desappear. Is my fault? I didn't change anything, I think :) Thanks in advance.

  • Generating the input id with an ActiveRecord model

    - by swilliams
    How do you generate an input's id attribute, given a model? For example, if I have a model of Person with a first_name attribute, the form helper prints out a textbox with this html: <input type="text" id="person_first_name" /> How can I generate that person_first_name from some other place in the code (like in a controller or some place)?

    What's the beste way to show a list with 20 images in rows of 5? Or, in other words, how do I clean up this ugly snippet? <div class="row"> <% @images.each_with_index do |image, index| %> <%= image_tag image.url %> <% if index != 0 && index % 5 == 0 %> </div><div class="row"> <% end %> <% end %> </div>

  • Rails - how to serialize a tree not in a form

    - by tiny_clanger
    I started with the standard scriptaculous drag and drop tree, and that all works fine. Then started implementing this: http://www.artweb-design.de/2008/5/30/scriptaculous-sortabletree which gives a good drag and drop tree Where I am stuck is how to get serialize the tree (unordered list)? It's not in a form, and I can't find a way to serialize it to move onto setting up the AJAX update.

  • [Rails] Accessing error_messages on form_tag

    - by aaronrussell
    I have built a custom form for creating a joining model on a has_many :through relationship. The models look roughly like this: class Team has_many :team_members has_many :members, :through => :team_members end class Member has_many :team_members has_many :teams, :through => :team_members end class TeamMember belongs_to :team belongs_to :member # and this model has some validations too end The form I have built is for selecting which members should be in a team. I won't paste the form, but it uses the form_tag method and basically sends an array of hashes which contain a member_id and a squad_number. I then update the database with an action that looks roughly like this (simplified a bit, but you get the jist): @team.transaction do @team.team_members = params[:team_members].collect{|tm| @team.team_members.new(tm)} if @team.save redirect_to ... else render :action => :members end end Everything works great but I am validating the squad_number for uniqueness and numerically. So, when any of those validations fail, how do I get access to them in my view, and how do I ascertain which of the many members it has failed on?

  • About presenter pattern in rails. is a better way to do it?

    - by Totty
    I have in my model: def presenter @presenter ||= ProfilePresenter.new(self) @presenter end The ProfilePresenter is a class that has methods like, get_link(), get_img_url(size), get_sex(), get_relationship_status() and other methods that have not to do with the model, not even with the controller but is used multiple times in the view. So now i use them by doing this: Profile.presenter.get_link # or Profile.presenter.get_img_url('thumb') # returns the path of the image. is not used to make a db query

  • Should I denormalize a has_many has_many?

    - by Cameron
    I have this: class User < ActiveRecord::Base has_many :serials has_many :sites, :through => :series end class Serial < ActiveRecord::Base belongs_to :user belongs_to :site has_many :episodes end class Site < ActiveRecord::Base has_many :serials has_many :users, :through => :serials end class Episode < ActiveRecord::Base belongs_to :serial end I would like to do some operations on User.serials.episodes but I know this would mean all sorts of clever tricks. I could in theory just put all the episode data into serial (denormalize) and then group_by Site when needed. If I have a lot of episodes that I need to query on would this be a bad idea? thanks

I know I got it working the first time, but now I get this error: undefined method `rename_table' for ActiveRecord::ConnectionAdapters::SchemaStatements:Module Was there something I need to set? Or am I going blind here.. Thanks!

  • Set a session hash outside of RoR program?

    - by Sindri Guðmundsson
    Hi, I have had my new rails program up for a few days now. I'm running it on Ubuntu 10.4 with apache2 in another location than the website it's made for (it's a standalone database application for physiotherapists). The people I made it for now want me to deploy it to the public part of their website, only with one change. Those who open it via the link in the public-part should not be able to click one button! I was thinking of doing something like this in my view: <% if session[:inside]%> <%=button_to 'Sækja mælitæki', @link_to_mt%> <%end%> How could I set session[:inside] only to true if the program was started from within the private part of the webpage? I thought of creating two new actions, the other would set session[:inside] to true and the other to false, but that seems to me like a security risk, is it not? BR, Sindri

  • Skipping authorization for certain methods

    - by mathee
    Per the Agile Development book, I have an Admin MVC that controls how users log in. In ApplicationController, I have a before_filter that checks for authorization. So, this will check that the user has logged in for every page. The problem is that I want everyone to be able to access the new method, for example, in Users (that is, anyone should be able to create a new user -- naturally! Only admin users should have access to the other methods in UsersController such as edit, etc.). What's the best way to do that?

  • session fixation

    - by markiv
    Hi All, I am new to web development, and trying to get a hold on security issues. I went through this article on http://guides.rubyonrails.org/security.html these are some of the steps the author has mentioned how an attacker fixes session. 1. The attacker creates a valid session id: He loads the login page of the web application where he wants to fix the session, and takes the session id in the cookie from the response (see number 1 and 2 in the image). 2. He possibly maintains the session. Expiring sessions, for example every 20 minutes, greatly reduces the time-frame for attack. Therefore he accesses the web application from time to time in order to keep the session alive. 3. Now the attacker will force the user’s browser into using this session id (see number 3 in the image). As you may not change a cookie of another domain (because of the same origin policy), the attacker has to run a JavaScript from the domain of the target web application. Injecting the JavaScript code into the application by XSS accomplishes this attack. Here is an example: <script>?document.cookie="_session_id=16d5b78abb28e3d6206b60f22a03c8d9";?</script>. Read more about XSS and injection later on. 4. The attacker lures the victim to the infected page with the JavaScript code. By viewing the page, the victim’s browser will change the session id to the trap session id. 5. As the new trap session is unused, the web application will require the user to authenticate. 6. From now on, the victim and the attacker will co-use the web application with the same session: The session became valid and the victim didn’t notice the attack. I dont understand couple of points. i) why is user made to login in step5, since session is sent through. ii) I saw possible solutions on wiki, like user properties check and others why cant we just reset the session for the user whoever is login in when they enter username and password in step5? Thanks in advance Markiv

  • rails 3.1 partial_updates doesn't seem to work with password

    - by user1306769
    i have a user model with a password attribute, which gets saved as password_digest. What i want to do is have the edit user page and the edit password page separated, so that the admin doesn't need to input the password everytime he needs to change something else. For this i have made an extra action / view. My problem is that when i update the user info, i get password validation errors even though i have no password field in the form. Which leads me to the conclusion that partial_updates isn't working with the password attribute (as i have already tested in the console that it is enabled, and it is) Is this me doing something wrong, or should i approach this differently?

  • Rails Routes Mappings

    - by rdasxy
    I'm a rails newbie, and I have a controller called resource_links that I've mapped to resources: resources :resources, :as => :resource_links, :controller => :resource_links And this works (basically /resources works as /resource_links). However, trying to go to /resources/tags does not work. To get around this, I added more mappings as: match 'resource_links/tag/:tag(.:format)' => 'resource_links#tag', :via => :get, :as => 'resource_links_tagged', :constraints => {:tag => /.*/} match 'resource_links/tags' => 'resource_links#tags', :via => :get, :as => 'resource_links_tags' Is there any way I can get /resources/tags to be mapped to /resource_links/tag?
