Hi! Is there a (simple) way to use alternative field names in validation messages? For example, if I have a validator like this one: validates_presence_of :email how can I make it print a message like "E-Mail Address can''t be blank" instead of "Email can''t be blank"? I can override the "can''t be blank" part by using the :message

Hi, how can I get the current URL withing a controller? There seems to be no appropriate method in ActionController::Base. I''m creating a site, which requires a login for some pages. I''m using before_filter for authentication. My idea was to store the currect URL in a session before redirecting to the login page and then redirect to this URL after successful authenfication.

Hi, when I generate a new rails project with a simple scaffolded controller, I get a strange error message, whenever it tries to call the url_for method, for example: ,---- | undefined method `rewrite'' for #<Url:0xb7675e64> | | Extracted source (around line #7): | | 4: </p> | 5: <% end %> | 6: | 7: <%= link_to ''Edit'', :action =>

Ahoy, I was able to follow the tutorials and build a simple to-do list program with Items and Categories and have the related tables link up w/ the default "scaffold :Items" command plus custom defenitions. Then I erased all of that and tried rebuilding the program using the ruby script/generate scaffold Item (and category) command. Now the templates look like " <% for

If you installed your copy of ruby via DarwinPorts, the hashbang lines at the top of your dispatch.* scripts says "#!/opt/local/bin/ruby". This is a problem, if you''re deployin via Capistrano to a host with a different path to ruby (which would be practially all of them:-) Here''s a fix.

I have a rails app that is accessed through Apache 2 (just using cgi now; will add fastcgi later when everything is working).

Hi all, In the code below I don''t understand: 1. Why I have to prepend overriden method content_columns with "self." to get it working? 2. Why column_for_attribute method is not working (no such method?) even if SomeTable is subclass of ActiveRecord::Base which have public column_for_attribute method? > class SomeTable < ActiveRecord::Base > > def

My code executes fully: <% for column in ModelName.content_columns %> <th><%= column.human_name %></th> <% end %> but it does not pick up any columns in my model''s table that end in "_id". Is this by design? Is there a helper method that will reference the related tables? Or will I need to code the column titles and detail records by

It appears that "smbclient -p <portnumber>" doesn't work as advertised in Samba 2.x? On both Linux 6.2 and Solaris 2.6, independent of firewalls and the like, it works with old Samba (e.g. 1.9.18p10) , but not with new Samba (e.g. 2.0.7). The new version seems to *IGNORE* the port specification and attempt to connect to port 139. Here's the result when I try to send a

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

All, I have ordered AWDWR and am anxiously awaiting its arrival. In the meantime I still am playing with ROR using radrails. I have a few questions ...

I''ve gone once through the Agile book and am now attempting my own rails app. I''ve created a table named ''volunteers'' with over 15 columns. The problem is the default list.rhtml that is created with the scaffold, shows all the columns. I only want to show 4 of them with the list view. Where would I start to only return a handfull of columns to the

I posted this problem as a question to this list a while ago and got no reply. I submitted it as a bug, but found that "samba-bugs@samba.org", no longer accepts bug reports, even though the web page says to send them to that address. Wondering if the option had been intentionally discontinuted without updating the man page, I made a quick check of the source and found that the "-p

Is there a way to call a method if I only have a string that contains the method name. For example: @methods = [''method1'', ''method2'', ''method3''] @step = 1 # I want to call method2 which has a definition in this class -- Posted via http://www.ruby-forum.com/.

Does anybody know how to turn a floating-point number (i.e. 60.345) into an integer by cutting off or rounding the decimal portion? Either method, or both, would be quite welcome. Thanks! This forum rocks! -- Posted via http://www.ruby-forum.com/.

All, I did a scaffold for a model and I ended up with this code in list.rhtml: <% for column in TargetList.content_columns %> <td><%=h target_list.send(column.name) %></td> <% end %> Where is the "send" method and what does it do? I can''t find it on ActiveRecord::Base? I assume that it returns a value based on the column id but I

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
