similar to: Altering the accessor of an association collection

How : <a href="/show/all">All</a> Could become : <a href="/show/all" title="Show All" >All</a> This is possible with the standdard link_to function ?

When a column in a database table is actual data, rather than an fkey to another table, I can override the automatic accessor by just doing the following: def field_name # do something here read_attribute(field_name) end This does not seem to work for me if the field is an fkey, say user_id, linking to another table. I''ve made this work by aliasing the accessor like this: alias

I have consulted the intro and nabble but have not found an answer to what should be a simple question, here goes: I am doing a crosscheck of a data frame and pulling out a single value based on an inputted value ie based on x i will select y, or if x =2 then my code returns 7. x y 1 4 2 7 3 10 4 2 My code currently iterates through for as many times as the length of the x

Hi, Haven''t been able to find this raised before but I''m sure it must have been. When assigning an object to a belongs_to association I would like it to call the *association*_id= method instead of directly updating the attributes array. This is because I want to modify the behaviour when assigning a particular object without writing separate methods for whether it''s

Hi, I am trying to overwrite the accessor of a has_many association. Basically my class looks like this: class Person has_many :emails has_one :link, :class_name => ''PersonProxy'' def emails_with_link link.emails + emails_without_link end alias_method_chain :emails, :link end Now that works fine if I only access the collection like >>

Hey all, this is a pretty simple question but I can''t seem to find anything on the wikki or google... Is there a Ruby/Rails equivilent to PHP''s nl2br function? -- Posted via http://www.ruby-forum.com/.

Hi there, I''d like to choose between an "static" and "dynamic" access of a reference class field, say ''a''. myObj <- getRefClass("Blabla")$new() Static: myObj$a Dynamic: myObj$a.get() where the function retrieves the data from a database (or some other location), stores it to a buffer and

Hi All Does any one know how to specify a different reverteffect on a draggable if its successfully dropped on a given droppable? What I need to do is when an image is dragged onto a droppable image I want the drop image to be replaced with the drag image, the drag image to fade out and then reappear where it was at the start of the drag, as opposed to the draggable scrolling across the page

Hi all, With webrick (i.e. "ruby script/server") is there a way to alter the starting URL? In other words, instead of "http://foo.bar.com", I''d like it to start at "http://foo.bar.com/myapp"? And, still be on port 3000? If it''s not possible, that''s fine. Just thought I''d ask. Thanks, Dan

I'm having a hard time modifying the legend that is emitted by default when calling plot(density(...)) and then legend(). I've looked at the docs and I'm not sure what I'm doing wrong, if anything. Any advice appreciated. Thanks, Brian

I have a model "Collection" which has a constant PATH. When in development or production mode, I want PATH == "data/images". When in test mode, I want PATH == "data/test/images". Here is my partial solution: The Collection class defines PATH so that it points the default (non-test) location. In my test file "collection_test.rb", I overrid that assignment

I have a set of PCs running WinXP and an Ubuntu Machine running Samba 3.0.28a. I am trying to achieve that each user that sits @ a PC be able to loging with their credentials and have their homes directory without login-logoff of each user at the station via the WinXP loging-logout screen. Any ideas?? C.

This may seem rather obvious, but how do I alter the window decorations, such as making the titlebar opaque, and changing it's colour? In CCSM -> Window Decoration -> Command I have set emerald, as I use KDE (on Ubuntu). The CCSM- > Window Decoration screen does not have an option for changing titlebar opacity or colour. The Emerald Theme Manager doesn't seem to be able to change

Does the error function *have* to be auto-generated in your pass? Perhaps the original code should use invokes, and your pass insert the error check with a jne to the "unwind" block.

Can't I do that during a Pass in llc? If you just have a magic block of instructions you want to

I'm working on a program that loads several large data files. I'm using ddply (plyr is really awesome) but I want to minimize the amount of times a large data file is read in. One solution is to keep track of which data file is open with a global variable and then change the currently open data file globally as needed. However, I'm unclear on how to alter a global variable
