  • Rails 2.3.5: How to handle this type of validation

    - by randombits
    The use case is simple. I allow users to enter in an expiration field which needs to be between 1 and 15 into a form. The model takes that number and converts it into a datetime (such as adding 15 days from today) and stores it in the database. What's the correct way to actually validate that though? Do I validate against the datetime format that gets persisted in the database or the select box (1..15) that the user gets to pick through the form? I want to be able to validate that the user is putting in 1..15.. How is this done with ActiveRecord validation in Rails 2.3.5?

  • Rails Form Submission, User can't be blank

    - by pmanning
    I'm trying to create an event through an event form and I keep getting a form error that says "User can't be blank". The event needs a user_id to post a feed_item showing who created the event.

    I am using form_for to create a form that has 1 input field and 1 button. I'd like the submit button to be beside the input field rather than underneath it. Relevant code is: .input{border: 1px solid #666666; width:400px; height:22px;font-size:16px;} <td width="900" height="50" align="left" valign="middle"> <% form_for @contact, :url => {:action => "create"}, :html => {:class => "input"} do |f| %> <%= f.text_field :email, :size=> 74 %> <%= image_submit_tag '2009-12-06-Landing1.gif' %> <% end %> </td>

  • Respond_with not working Rails 3

    - by MDM
    As no one can help me with my UJS ajax problem I am trying "respond_with", but I am getting this error: RuntimeError (In order to use respond_with, first you need to declare the formats your controller responds to in the class level) Yet I have declared it in my controller: class HomepagesController < ApplicationController respond_to :html, :xml, :js def index @homepages = Homepage.search(params[:search]) respond_with(@homepages) end Anyone has any ideas why.

  • Optional mix of filter parameters in a search the Rails way.

    - by GSP
    I've got a simple list page with a couple of search filters status which is a simple enumeration and a test query which I want to compare against both the title and description field of my model. In my controller, I want to do something like this: def index conditions = {} conditions[:status] = params[:status] if params[:status] and !params[:status].empty? conditions[???] = ["(descr = ? or title = ?)", params[:q], params[:q]] if params[:q] and !params[:q].empty? @items = Item.find(:all, :conditions => conditions) end Unfortunately, it doesn't look like I can mix the two types of conditions (the hash and the paramatized version). Is there a "Rails Way" of doing this or do I simply have to do something awful like this: has_status = params[:status] and !params[:status].empty? has_text = params[:q] and !params[:q].empty? if has_status and !has_text # build paramatized condition with just the status elsif has_text and !has_status # build paramatized condition with just the text query elsif has_text and has_status # build paramatized condition with both else # build paramatized condition with neither end I'm migrating from Hibernate and Criteria so forgive me if I'm not thinking of this correctly... Environment: Rails 2.3.4

  • Rails: Modeling an optional relation in ActiveRecord

    - by Hassinus
    I would like to map a relation between two Rails models, where one side can be optionnal. Let's me be more precise... I have two models: Profile that stores user profile information (name, age,...) and User model that stores user access to the application (email, password,...). To give you more information, User model is handled by Devise gem for signup/signin. Here is the scenario of my app: 1/ When a user register, a new row is created in User table and there is an equivalent in Profile table. This leads to the following script: class User < ActiveRecord::Base belongs_to :profile end 2/ A user can create it's profile without registering (kind of public profile with public information), so a row in Profile doesn't have necessarily a User row equivalent (here is the optional relation, the 0..1 relation in UML). Question: What is the corresponding script to put in class Profile < AR::Base to map optionally with User? Thanks in advance.

  • Rendering HTML in rails without actually displaying it

    - by Kevin Whitaker
    Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

  • Update paths of already-created Paperclip attachments

    - by Horace Loeb
    I used to have this buggy Paperclip config: class Photo < ActiveRecord::Base has_attached_file :image, :storage => :s3, :styles => { :medium => "600x600>", :small => "320x320>", :thumb => "100x100#" }, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => "/:style/:filename" end This is buggy because two images cannot have the same size and filename. To fix this, I changed the config to: class Photo < ActiveRecord::Base has_attached_file :image, :storage => :s3, :styles => { :medium => "600x600>", :small => "320x320>", :thumb => "100x100#" }, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => "/:style/:id_:filename" end Unfortunately this breaks all URLs to attachments I've already created. How can I update those file paths or otherwise get the URLs to work?

  • To use an api or store a large dataset in a rails app?

    - by Dave
    Hi all- I am working on a site that has the potential to need a LOT of space. Basically we hope to have every video game every created stored in a database along with an image of the cover. There are some api's out there that might be able to help, like GiantBomb's (www.giantbomb.com). We are trying to decide whether to store the data locally and if so where to find that comprehensive a list, or make calls to the api on demand. The problem with the latter is likely latency and also downtime problems. Assuming we want to store it locally here are the questions: 1) Where can we find this kind of data (yes, I looked on google, and no I couldnt find anything:)) 2) What is the most efficient way to encode and store the images? Thanks!

  • Why is rails called a dsl?

    - by b_ayan
    Recently, when I tried to explain why Rails is a DSL to an intern at my organisation, I was not able to articulate my reasonings to the effect I would like to. Maybe I do not understand the space well enough to teach the nuances. Redirecting him to Martin Fowler' article or the google ranked one InfoQ or other material has not helped much either. Can some explain why Rails is a DSL with an example / parallel situation which is not voodoo stuff for someone who is fairly new to the world of code? Understanding the ideology might also help in elaborating the intricacies of the rails ecosystem?

  • Rails active record association problem

    - by Harm de Wit
    Hello, I'm new at active record association in rails so i don't know how to solve the following problem: I have a tables called 'meetings' and 'users'. I have correctly associated these two together by making a table 'participants' and set the following association statements: class Meeting < ActiveRecord::Base has_many :participants, :dependent => :destroy has_many :users, :through => :participants and class Participant < ActiveRecord::Base belongs_to :meeting belongs_to :user and the last model class User < ActiveRecord::Base has_many :participants, :dependent => :destroy At this point all is going well and i can access the user values of attending participants of a specific meeting by calling @meeting.users in the normal meetingshow.html.erb view. Now i want to make connections between these participants. Therefore i made a model called 'connections' and created the columns of 'meeting_id', 'user_id' and 'connected_user_id'. So these connections are kinda like friendships within a certain meeting. My question is: How can i set the model associations so i can easily control these connections? I would like to see a solution where i could use @meeting.users.each do |user| user.connections.each do |c| <do something> end end I tried this by changing the model of meetings to this: class Meeting < ActiveRecord::Base has_many :participants, :dependent => :destroy has_many :users, :through => :participants has_many :connections, :dependent => :destroy has_many :participating_user_connections, :through => :connections, :source => :user Please, does anyone have a solution/tip how to solve this the rails way?

    - by VP
    Hi, I would like to know if it is possible in rails to run some test cases through my application. I mean, i want show the test results to users. So i was thinking to be able to call my tests through a controller and put the tests output in a dialog. Imagine that i'm doing an application where before to apply a rule, i want to run some validation tests. I could write methods in my rule model to do it, but i would like to use something like shoulda or any other kind of DSL where the "fixture" would be a record itself. Any tip or idea?

  • link_to_remote and jquery accordion

    - by badnaam
    I have a standard jquery ui accordion and I load content into it using a link_to_remote tag (in the accordion header). All this works fine. The problem is, once the content is loaded, I dont want a ajax call, I just want the accordion to fold, like it should normally do. I tried doing this using the following jquery but clicking the header hence the link still makes a request. #lbs_list is the div inside the accordion. $j('#lnk_show_benefit').bind('click', function(e) { if ($j('#lbs_list').is(':visible')) { e.preventDefault(); return false; } else { return true; } });

  • How Would you Mimic an Arbitrary Directory Structure with Rails Routes?

    I want to be able to map Google Docs' folder system to urls in my application and am just wondering how I can say "route, I want you to match an arbitrary set of nodes, and the last one is the file (or possibly a directory, I can check in the controller)". So I could do things like: www.mysite.com/documents/folder1/childfolderA/document www.mysite.com/documents/root-level-doc Can the routes.rb file do something like this?
