Hi! I''m looking for a good tutorial that explains the main points of performing queries with Rails. I do have AWDWR and have read the section on ''find'' but I''m looking for something that goes into more detail on how to perform queries across tables. Abstracted from my current application, this is an example: * person has_many sites * site has_one room *

In an *.rhtml, why do I need to add <% for product in @products %> in order that I may call an <img class="list-image" src="<%= product.img_url %>"/>. Is there not another way to skip the "for product" line? I really dont want to include it. I tried @products = product but it does not work. Can anyone help shed light on this matter? -- Posted via

Hi, Quick question (which means that I think there should be an easy answer)... When I am in the "show" view, I''d like to add 2 links, one for previous and one for next record so that the user can go on to the next "result" without having to go back to the ''list'' of results. However, I can''t find my way about this problem :-S

I''ve been experimenting with Rails over the past couple of days and have come across something that seems harder than it should be. In previous frameworks I have used (WebObjects, php) a full search page (which leads into a list view populated with search results) was part of the CRUD that was either dynamically or statically created after specifying table/object schema. In

Again, I find that I''m stumped trying to concisely attach a subject to my query... Sorry about that :-S Also, I apologize if the query is a bit off-topic, but I hope that it is relevant!

I''ve been reading the tutorial and I have problems with the TinyInt(1) for the attribute "item.done". I thought this thread would be the best to post it. I''m using Rails 1.1.14. When in the partial template _list_stripes appears: <%= list_stripes["done"] == 1 ? show_image("done_ico.gif") : "&nbsp;" %> it always returns the

How''s the experience with using ActiveRBAC? For my "next 4 days with rails" :P I''d like to consider adding Role-based access to the To-Do List application in the original "four days w/ rails" tutorial. Just wondering if ActiveRBAC would be a good place to start? Thanks! For those who are wondering: https://activerbac.turingstudio.com/trac Cheers Mohit.

I have a text field that I use for logging in users. Due to the design of my site, I don''t have room to put the word "username" in front of the text field so I''d like to actually display it inside the field and then have the word clear when the user clicks on it. How could I modify something like this <%= text_field "user", "login", :size

Hi Guys, I am trying to paginate the results from a search. When I use actual constants in the search conditions, it works fine: def query @k2_result_pages, @k2_results = paginate (:k2_results, :conditions => [''e_date >= ? AND e_date <= ?'', ''2006-07-12'', ''2006-08-12''],

Hi all, I need to write an application that gets data from a database and plots it on a graph. I am familiar with java and know that I could do it with jfreechart - however I am excited by RoR and would like to write the application with RoR instead. Is it possible to write it in RoR?

Just wondering if anyone knows of a site where one could review a number of website layouts (which use CSS concepts) where you could then select the one you want and then just download the template HTML and CSS to import directly in your application. i.e. Gives you a decent overall look and feel straight away and then you can concentrate on your actually dynamic application aspects. Cheers

Is there an addition to the Rails Recipe or the method in AWDWR to allow a user to change his/ her password? I have put something together that does all the work again - mostly because I''m not sure how to leverage on methods like ''password='' that are defined in the model. Has anyone got a ready sample that I could learn from? Right now, I''m basically

The Textile Editor Helper (TEH) is a Javascript-based text formatting toolbar that will be added to all of your text areas that utilize the TEH feature.

I''m sorry - just couldn''t come up with a subject that describes the problem :( Anyway, this is my problem. I have a long list of fields that need to be displayed when a ''show'' is requested on the controller. I''m now doing the list.rhtml and looking for a DRY way to do the following.

Hi, I have a Windows program that collects data and would like to store this data in a database that is usually accessed through Rails. It was recommended that I try to "POST" the data to the Rails application. I''m running into some problems trying to format my POST string for the application. I''m trying to learn by interfacing to the TODO application (Four Days

Hi there, This is what I would like to do: the user selects data that they would like from the database. The app gets the data and saves it to a .txt file (or preferably a .csv file so they can look at it in a spreadsheet such as Excel) The file is saved to the users computer or the user downloads it. Is this possible with RoR? Chris. -- Posted via http://www.ruby-forum.com/.
