I''m trying to get the id of the previous row prior to what would be input and then rename an uploaded image to that row number. So say the previous row was 19 and the image in that row was named 19.jpg, I''m wanting to name the next uploaded image as 20.jpg since the row that would be added then would be 20. Right now I''ve just got: @new_tutorial =

Hi, I seem to remember seeing the equivalent of saving only if all attributes are different. I can''t seem to find that now in the API or the agile book. I''m using the acts_as_versioned and only want to save if the input is different. Thanks, Steve http://www.smarkets.net -------------- next part -------------- An HTML attachment was scrubbed...

I''m trying now to do "sudo fixrbconfig" in the terminal, and I get this: /usr/lib/ruby/1.8/powerpc-darwin8.0/ruby.h does not exist. This probably means you haven''t yet installed Xcode from the Tiger DVD. You won''t be able to compile Ruby extensions without it. Please install it then rerun this program. I''m on an intel mac.

I think I am missing something terribly obvious. Is it possible to have an :expects parameter for a webservice that is an array of objects? I want to have a single webservice that expects all my line items (for an order). Is this something that is possible? -- Posted via http://www.ruby-forum.com/.

Dear experts, I am in the process of switching servers for my application. Before the move everything was working properly. After the move <%= stylesheet_link_tag ''/stylesheets/styles.css'' %> generates <link href="//stylesheets/styles.css" media="screen" rel="Stylesheet" type="text/css" />

Hi, I have a strange problem with testing classes which have a HABTM relation. It seems that while running my tests with rake the fixture for the association table is not loaded - as a result I get a failure on a test which simply checks the number of associated elements - it says it''s 0 although there should be one. The weird thing is that when I run the tests with rcov

Hi, I have a standard type authentication technique direct from AWDWR, so there is a before_filter :authorize_employee, :except => :login in my employees_controller.rb the authorize_employee is in application.rb def authorize_employee unless session[:employee_id] flash[:notice] = "Please log in" # save the URL the user requested so we can hop

I have a database with a couple of tables. One table called spares has foreign keys in another called equipment. When I create a new record, it is added to the spares table however the list action does not show all the columns in the table. It only shows those columns that are not foreign keys. I am using the default action generated by scaffold for list. Why is that so? Do i need to re-write my

Ok, I''m hoping this won''t be a forehead slapper, but take a look at this code: physician.name.sub(/''/, "\\''") I''m trying to substitute a single quote with a backslash and a single quote. This seems pretty simple right? Well, someone kick me and tell me why it''s not :) Here''s what I''m getting if the

Hello, this is a typical "how do you do it in Rails" question :) I would like to incorporate fit testing into a RoR app and I''d like to hear your recommendations on how to do it. In the ideal world I would like all the table test definitions and implementations stored in svn together with the app, ability to run the tests with a rake task + a hook to FitNesse, so that

I''m returning some rows from a tags database that look like this: ID WORDS 1. apple banana pear 2. banana melon 3. apple peach lime What I want to do with that data is use the .split method to divide them into separate values in an array, then use the .uniq method to return a unique list of the words like so: apple, banana, pear, melon, peach, lime So in my controller I

Hi, I''m trying to include a partial in an email template but it throws me this: undefined method `controller_path'' for SupportMailer:Class Extracted source (around line #12): 11: 12: <%= render :partial => ''footer'' %> I guess email views are a little different from normal ones as they don''t seem to have a access to a proper controller (?)

I have the model that acts as list acts_as_list :scope => ''featured=1'' As you can see, I only need to order the records that are featured. However, from time to time I switch some featured items off and mark others as featured. When this is done, I start getting dublicate numbers on the list and ordering starts getting problem...

I am using the ACL System that is described on the Rails wiki and I have a quick question. I want to set the "role" as a session variable so that I can display certain navigation schemes and I was doing it like this: @session[:user][:role] = @user.roles When I print out this variable I get: #<Role:0x3262d80> How can I turn this into a readable value?

Hello, I''m a novice to ferret, so far only used it via acts_as_ferret. My question is about a recommended pattern for an ''advanced search'', which would be searching by all fields of a model and some fields from related models, with range search, expression search and wildcards. The kind of search in which a user is presented with a huge form that allows them to set

I looked everywhere but couldn''t find it. I don''t want a submit_tag or image_submit_tag but a normal link that submits my form. Normally I would do this with a javascript like function sendForm () { document.forms[0].submit(); } but this doesn''t work with form_remote_tag link_to_function( ''Send'' , "sendform();") So the question is:

I tried to use a before_save and use simple_format, it returns and undefined method error. Can I even use these methods within a model? I tried to use auto_link and it failed too. What am I doing wrong? Furthermore, would it be recommended I format text before saving it to the database? Advantages or disadvantages? -- Posted via http://www.ruby-forum.com/.
