Hi all, I can''t figure out why my radio_buttons won''t reflect the values stored in my database. I read through some of the previous posts -- is it true that they don''t work with integers? This is the code I''m using: <% for question in @survey.questions %> <%= debug question %> <%= radio_button ( "question", :question_id,

Hi, I am thinking about how to best design a quiz site in RoR. I think it should be fairly easy, but have run into a wall. In the simplest form, the view would grab all of the questions for a particular quiz and display them (e.g. multiple choice, so 4 option buttons per question). However, I can''t figure out how to "mark" the quiz. The form is submitted to the

Hi hi i have a problem trying to connect to the mysql database when I do a rake it says: Access denied for user: ''@localhost'' to database '''' My database.yml file is fine Any ideas why this is happening -- Posted via http://www.ruby-forum.com/.

Hey all, This example of working code: @a = @b.where(:a_group_id.ne => nil).collect { |b| b.a_group } doesn''t make too much sense to me. For one, I am not sure what that "ne" is doing there. Is this a postgresql thing? Second, it looks like we are collecting active record objects where the a_group_id is null, collecting them in an array and then invoking the a_group

Maybe I misunderstand the parameterization of find(), I am getting this syntax error for <% @choices = Choic e.find(:all, :conditions => "question_id" = question.id, :order => "order") %> ---- ERROR LOG ---- ActionView::TemplateError (compile error ../config/../app/views/admin/test/show.rhtml:37: syntax error _erbout.concat " "; @choices =

I''ve been reading my Agile Dev book over and over again, but I can''t wrap my head around how to do this. There''s a question and answer portion site of my site. You begin the process by adding a question to the database. After that, the program should redirect you straight to adding an answer for that question. The problem is, I don''t know how to keep

Please could someone suggest what might be wrong here. In my view I''m displaying a series of check boxes and when the form is submitted I want the controller to iterate over the values and contatenate them all into a string "1" if the box was checked and "0" if it wasn''t. I''m new to Ruby and Rails and I can''t seem to get any values out of

Hi list, My tag_question_user join table is not currently a full-blown model. It doesn''t have a primary key - just tag_id, question_id, and user_id. I now want to add a primary key to this model (because I want to add a "description" column as well so users can describe the tag. I''m not sure how to add this using migrations. Here is what I have: class AddNotesToTags

I am having problems updating a div defined in a partial using both Element.update and page.replace_html in an rjs. I can put a link_to_remote in the partial using an :update, and the div updates fine. Does anyone have any idea why this might be happening? In the partial: <div><div> . . <div id="question_<%=question.id%>_error"></div> . (if a

I''m having problems unit testing my model- I have a kind of quiz functionality user table and a question table and a user_question_response table that contains the id for the user, the id for the question and the user''s response. The user_question_response has it''s own model belongs_to/has_many with users and questions and it works fine in the actual application but

Hello all, I found this dialog on the zfs-devel at zfsonlinux.org list, and I''d like someone to confirm-or-reject the discussed statement. Paraphrasing in my words and understanding: "Labels, including Uberblock rings, are fixed 256KB in size each, of which 128KB is the UB ring. Normally there is 1KB of data in one UB, which gives 128 TXGs to rollback to. When ashift=12 is

Hi Working through the tut material in teh PP book (agile dev with rails) on a laptop running winxp. Creating the "admin" application, things generally work great. Except: at teh end of chapter 6, when we update teh css to improve the look of the page - I copy the new scaffold.css into my working directory, but webrick keeps serving the old css, even after a restart. Very odd. The

Hi, I have a Question model where the answer to the question can have multiple db type (integer, string, boolean, ...). I would like to know if you have a better solution than this one: Question: question:string answer_type:string AnsweredQuestion: question_id:integer answer:text answer_type:string Ex: AnsweredQuestion.create(:question => 1, :answer => ''5'',

I am using SER as a proxy, and using Asterisk as a PBX. A user calls in to a 1-800 number. They listen to the IVR on one Asterisk PBX, and then are transferred to the call center at the other Asterisk PBX. Calls are being brought into the system via SIP. I need to transfer users from one Asterisk box to the other. Functionally this works fine, practically it doesn't as Asterisk forces the

Hi folks, Just after a ''best-practise'' recommendation here really, I am deploying a series of applications to EY and for each one, need to setup the database with some default settings / user account etc etc. What is the best way to write a few initial rows to a vanilla database? I''ve looked into using the deploy hooks on EY but it doesn''t seem to cover DB

I have the test posted at http://rafb.net/paste/results/YjWkIh45.html... when I run it, the test fails, but the db table is never restored & it seems that the fixtures file was never loaded... Any ideas as to what I''m doing wrong? Thanks! -- Posted via http://www.ruby-forum.com/.

CVS HEAD/Asterisk 1.2: Is there a way to have the entire extensions.conffile coming from the realtime? It appears that RealTime for the extensions.conf file is on a context by context basis, but you have to create each new context in the extensions.conf file then add a "switch => Realtime" line (then reload). I want to be able to add phones without having to edit any files.

Hi all Am i doing this right? Is this the right list to post to? If not, a quick lesson in ettiquette for me would not hurt.
