I have a text file that has data in it which is perfectly formatted the
way I want it.
I have the following code in my controller to open the file and read
each line into an array which I then call from my view. The problem is,
I completely loose the formatting the way I'm doing it:
<%= ... %> basically just calls to_s on whatever the expression in
there evaluates to, and to_s on an Array is just the concatenation of
to_s called on everything in it. If you just want to display data from
the file, why not use @my_data = File.read(...) ?
Here is the data, if you put it in a file and then tell Rails to read
it, please see if you can get it to display in the exact same format in
Rails. When I do it, all my columns don't line up:
Mod Ports Card Type Model
Serial No.

...hehe....I know, I'm sorry that wasn't much of a help
Are you trying to display this in PRE tags or equivalent CSS with a
monospace font?
..good call on this one though, I added PRE tags on my index.rhtml and
the data is looking the way I want it...which is great news.
I am still a bit baffled as to why I have to write the data to a file
first, then open the file and put it in PRE tags as opposed to using
PUTS statements in my original script and assigning that to a variable
which gets called by my index page which still causes the format to be
skewed.

my_data.rb code:
data.each do |line|
a.write(line) #--this writes to my_data.dat
puts line #--this puts the same data to STDOUT
end
---
controller code:
def index
@my_data = `/usr/bin/my_data.rb` #this causes data to be skewed
#@my_data = File.open("/usr/bin/my_data.dat").read #this works
end
---
index.rthml code:
<pre><%= simple_format @my_data %></pre>
puts always appends a carriage return whereas write doesn't. if you
changed it to STDOUT.write(line) it should be the same
