What I'd ideally like to do is offer user profile URLs like this: http://example.com/joeschmoe So, what sort of route and controller magic needs to happen to pull that off? ...
Some functionality within my rails application looks better as if it was a separate "module", that should be accessed via require. For example, assume it's a function to calculate Fibonacci numbers. The functionality is independent on rails application and can be reused in other projects, so it should not be stored near application co...
I have a problem, trying to render partials in ruby on rails with the short notation for resoures. Somehow, RoR displays simply nothing that has to do with the partial, but i get no errors as well. I mean, the resulting HTML looks like the call for the partial simply wouldn't be there. I'm also confused, because i can see in the log, tha...
Trying to use my active record translations in config/locales/de.yml also in my views. I thought I am clever using this: de: activerecord: attributes: user: login: "Benutzerkennung" comment: "Bemerkungen" And in my view this: <%= label_tag :login, t('activerecord.attributes.user.login') %> But instead o...
I'm using paperclip for attachments in my application. I'm writing an import script for a bunch of old data, but I don't know how to create paperclip objects from files on disk. My first guess is to create mock CGI multipart objects, but that seems like a bit of a crude solution, and my initial attempt failed, I think because I didn't ge...

I began writing an app using declarative_authorization (http://github.com/stffn/declarative%5Fauthorization) but I'm now wondering if it's the correct approach. In my app, I was giving some Users a "customer" role, some an "administrator" role, and some a "superadmin" role. That was working fine, but I now realise that I need some field...
Lets say you had a simple form to create a new article object in your application. <% form_for @article do |f| %> <p> name:<br /> <%= f.text_field :name %> </p> <p> link:<br /> <%= f.text_field :link %> </p> <p> <%= submit_tag %> </p> I'm using the RSS feed parser Feedtools to get the article names but I can't seem to auto...
So I have a url like the following localhost/users/:id/posts which gives the posts of that particular user. Now this id can be either his login (which is a string) or the id (user.id) which is technically an Integer but params[:id] is always a string. So how do I implement this an action. @user = params[:id].is_a?(String) ? User.find...
Hi all I have the following code: @profile.update_attributes(params[:xxxx_profile]) where xxxx stands for either male or female.

I'm trying to use mechanize to perform a simple search on my college's class schedule db. The following code returns nil, however it works logging into facebook and searching google (with diff url/params). What am I doing wrong? I'm following the latest (great) railscast here. Mechanize documentation has been useful but I'm still puzzle...
I'm having the most peculiar problem, and I was hoping I someone could point me in the right direction on how to address it (or even locate it...). I'm working on a rails site, and the pages display in most browsers without any issues. In others (AOL, IE 6 - 7, and some of the other lesser used ones) the page will load, with all of the...
First let me say I cannot do gem install, I don't know why. Probably because I live in China and the firewall random things. So I have to locally install gems. For example, i want to install this gem riddle. But this gem downloads as a tar or zip and when i open it it is a folder not a .gem file. So what to do? ...

As a result, all of my CRUD pages are currently automatically generated, and I even have ability to inject additional HTML code whenever I want to to further customize the content of those pages.
