Problem processing text file after uploading
I''ve got a web-app currently partially working. The user uploads a .txt,
.docx or .doc file to the server.

a txt file.
My problem is I want to copy the plain text contents of

Freezing one gem in Rails 3
Hi,
I''m working on an app for a colleague.
He has written his own pagination class, but it is buggy and not
very DRY. Therefore I replaced it with the well-known "will_paginate"
gem, and that works just great.
The only problem is, that although this works on my machine, my
colleague (for whatever reason) refuses to install any additional gems
on his machine (I guess this is

Help displaying text
Apologies in advance ...this may be a really dumb question but here
goes.
@formatted_question[:a] contains text with HTML markup. I want to
display it in a field so I can control its vertical and horizontal size
on the page. When it is displayed on the page now, rather than
interpreting the HTML, it is output into the text field as a string with
all HTML tags showing. What am I doing wrong??

db/migrate/*. After that, the ORM makes the mapping with de Database.
