  • How to create a session in PHP when there is a session on the same domain in Rails?

    - by Tony
    I have a Rails app on a subdomain - xyz.domain.com, and a PHP app on another subdomain - abc.domain.com When a user is logged into the Rails app, I would like to give them a session so that I can log certain events about that user in the PHP app but in the same database of the Rails app. I would essentially just expose an API that requires authentication. What is the best way to go about this? I am not storing the session in a database

  • Rails paginate existing array of ActiveRecord results

    - by SaoiseK
    Hello, I generally use will_paginate for the pagination in my app, but have hit a stumbler on my search feature. I'm using Thinking Sphinx for doing my full-text search, which returns results paginated. The problem I'm having is that after I've received the results from Thinking Sphinx, I need to merge them with some other results and re-order them. Once I've finished processing them I have an Array of results that is very different from the original from TS. As there could be 1000+ results in this Array Pagination is a necessity. The problem is that I can't figure out how to get will_paginate to play with an existing array. I've done some research and it seems the only solutions to this problem are from several years ago and are based around the old built-in Paginator class. The most recent one I could find that makes use of will_paginate was from devchix from mid-2007: http://www.devchix.com/2007/07/23/will_paginate-array/comment-page-1/ - I've given this a go but it doesn't seem to do anything for me. Are there any current methods for applying pagination (preferably via will_paginate) for existing arrays of AR results?

  • .save puts NULL in id field in Rails

    - by mathee
    Here's the model file: class ProfileTag < ActiveRecord::Base def self.create_or_update(options = {}) id = options.delete(:id) record = find_by_id(id) || new record.id = id record.attributes = options puts "record.profile_id is" puts record.profile_id record.save! record end end This gives me the correct print out in my log. But it also says that there's a call to UPDATE that sets profile_id to NULL. Here's some of the output in the log file: Processing ProfilesController#update (for 127.0.0.1 at 2010-05-28 18:20:54) [PUT] Parameter: {"commit"=>"Save", ...} ?[4;36;1mProfileTag Create (0.0ms)?[0m ?[0;1mINSERT INTO `profile_tags` (`reputation_value`, `updated_at`, `tag_id`, `id`, `profile_id`, `created_at`) VALUES(0, '2010-05-29 01:20:54', 1, NULL, 4, '2010-05-29 01:20:54')?[0m ?[4;35;1mSQL (2.0ms)?[0m ?[0mCOMMIT?[0m ?[4;36;1mSQL (0.0ms)?[0m ?[0;1mBEGIN?[0m ?[4;35;1mSQL (0.0ms)?[0m ?[0mCOMMIT?[0m ?[4;36;1mProfileTag Load (0.0ms)?[0m ?[0;1mSELECT * FROM `profile_tags` WHERE (`profile_tags`.profile_id = 4) ?[0m ?[4;35;1mSQL (1.0ms)?[0m ?[0mBEGIN?[0m ?[4;36;1mProfileTag Update (0.0ms)?[0m ?[0;1mUPDATE `profile_tags` SET profile_id = NULL WHERE (profile_id = 4 AND id IN (35)) ?[0m I'm not sure I understand why the INSERT puts the value into profile_id properly, but then it sets it to NULL on an UPDATE. If you need more specifics, please let me know. I'm thinking that the save functionality does many things other than INSERTs into the database, but I don't know what I need to specify so that it will properly set profile_id.

  • rails delete_all exception

    - by Sergei
    Hello, guys! I have some User model, Role model and Assignment model to manage role-based user system. Just like here . So, here some kind of code, to include roles into users form: <% for role in Role.all %> <%= check_box_tag "user[role_ids][]", role.id, @user.roles.include?(role) %> <%=h role.name %><br /> <% end %> And all's working fine for new records and for editing records. But I just want to make possible to restrict deleting Assigment with id=1, cause this Assignment for default root user from migration, who must be admin anyway. Otherwise, I can lose my last admin. So I've tryed to add before_destroy to Assignment.rb model, but it doesn't work. I've noticed, that when I'm editing user and trying to remove his admin role(assignment), the server makes a delete_all method, not destroy method. So, does anybody know how to catch the deleting of Assignment with id=1 through this kind of code? Thanks in advance!

    I feel like this might be really simple but I'm just not getting it right, so I have like a settings page in my app and I want each setting to be like a key value store, for example: +-------------------+--------------------------------+ | setting | value | +-------------------+--------------------------------+ | twitter_username | something | +-------------------+--------------------------------+ | facebook_url | http://facebook.com/someguy | +-------------------+--------------------------------+ My form looks something like this: <% form_tag set_admin_settings_path, :method => :put do %> <ol> <% for setting in @settings %> <li class="field"> <label><%= setting.setting_name.humanize %></label> <%= text_field_tag "[setting_value][]", setting.setting_value %> </li> <% end %> <li class="submit"> <%= submit_tag "Update settings" %> </li> </ol> <% end %> Everything renders fine but when I try to save the form, nothing is saved :(

  • Rails, Edit page update in a window

    - by Mike
    I have my code working so that I have a table of businesses. There's a pencil icon you can click on the edit the business information. The edit information comes up in a partial inside of a modal pop up box. The only problem is that once they make the changes they want and click update, it sends them to the 'show' page for that business. What I want to happen is have the pop up box close and have it update the information. This is my update function in my controller. def update @business = Business.find(params[:id]) respond_to do |format| if @business.update_attributes(params[:business]) flash[:notice] = 'Business was successfully updated.' format.html { redirect_to(business_url(@business)) } format.js else format.html { render :action => "edit" } format.xml { render :xml => @business.errors, :status => :unprocessable_entity } end end end I tried following railscast 43 and i created an .rjs file but I couldn't get that to work at all. My update was still taking me to the show page. Any help would be appreciated. EDIT: Added some more code. <% form_for(@business) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> ... <%= f.label :business_category %><br /> <%= f.select :business_category_id, @business_categories_map, :selected => @business.business_category_id %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> This is my form inside of my edit page which is being called through the index in a pop up by: <div id="popupEdit<%=h business.id %>" class="popupContact"> <a class="popupClose<%=h business.id %>" id="popupClose">x</a> <% if business.business_category_id %> <% @business = business %> <%= render "business/edit" %> <% end %> </div>

  • Group and sort blog posts by date in Rails

    - by Senthil
    I've searched all over web and have not found the answer. I'm trying to have a very standard archive option for my blog based on date. A request to url blog.com/archive/2009 shows all posts in 2009, blog.com/archive/2009/11 shows all posts in November 2009 etc. I found two different of code but not very helpful to me. def display_by_date year = params[:year] month = params[:month] day = params[:day] day = '0'+day if day && day.size == 1 @day = day if (year && month && day) render(:template => "blog/#{year}/#{month}/#{date}") elsif year render(:template => "blog/#{year}/list") end end def archive year = params[:year] month = params[:month] day = params[:day] day = '0'+day if day && day.size == 1 if (year && month && day) @posts_by_month = Blog.find(:all, :conditions => ["year is?", year]) else @posts_by_month = Blog.find(:all).group_by { |post| post.created_at.strftime("%B") } end end Any help is appreciated.

  • Rails: RESTful Find, Initialize, or Create

    - by Andrew
    I have an app that has Cities in it. I'm looking for some suggestions on how to RESTfully structure a controller so that I can lookup, initialize, and create city records via AJAX requests. For instance: Given a text field city_name A user enters the name of a City, like "Paris, France" The app checks this location to see if there is such a city in the database already If there is, it returns the city object If there is not, it returns a new record initialized with the name "Paris" and the country "France", and prompts the user to confirm they want to add this city to the database If the user says "Yes" the record is saved. If not the record is discarded and the form is cleared. Now, my first approach was to change the Create action to use find_or_create, so that an AJAX post to cities_path would result in either returning the existing city or creating it and returning it. That works ok... However, it would be better to setup controller actions that would take a string input, find , or else initialize and return, then only create if the user confirms the generated record is correct. The ideal scenario would put this all in one action so AJAX request can go to that url, the server responds with JSON objects, and javascript can handle things from there. I'd like to keep all the user-interaction logic client side, and also minimize the number of requests it takes to achieve this. Any suggestions on the cleanest, most RESTful way to accomplish this?

  • Rails 3 Join Question for Votes Table

    - by Dex
    I have a table posts and a polymorphic table votes. The votes table looks like this: create_table :votes do |t| t.references :user # user_id t.vote # the vote value t.references :votable # votable_type and votable_id end I want to list all posts that the user has not yet voted on. Right now I'm basically taking all the posts they've already voted on and subtracting that from the entire set of posts. It works but it's not very convenient as I currently have it. def self.where_not_voted_on_by(user) sql = "SELECT P.* FROM posts P LEFT OUTER JOIN (" sql << where_voted_on_by(user).to_sql sql << ") ALREADY_VOTED_FOR ON P.id = ALREADY_VOTED_FOR.id WHERE (user_id is null)" puts sql resultset = connection.select_all(sql) results = [] resultset.each do |r| results << Post.new(r) end results end def self.where_voted_on_by(user) joins(:votes.outer).where("user_id = #{user.id}").select("posts.*, votes.user_id") end

  • Rails callback for the equivalent of "after_new"

    - by Joe Cairns
    Right now I cant find a way to generate a callback between lines 1 and 2 here: f = Foo.new f.some_call f.save! Is there any way to simulate what would be effectively an after_new callback? Right now I'm using after_initialize but there are potential performance problems with using that since it fires for a lot of different events.

  • Is it possible to send an automated email with dynamic content in Rails

    - by Danny McClelland
    Hi Everyone, I am looking into the best way of doing the following: I have a model called Kase, and when a user creates a new case then are taken to the show view as you would expect. I am trying to work out what the best way of sending an automated email between those two events is. I would need to include in the email the content of a couple of the fields, ideally I am looking for a way of just typing out the email and adding the same snippets that are in the show view for each of the fields I need. I am using the Base App from Github so the email sending is already setup for the user authentication and registration, but I'm not sure where to begin. The reason I want to send the email is to create a new Case in our Highrise account, and I don't have a clue how to use the API. So I think the email sending is the easier way. Thanks, Danny
