Rails - Sep 2006 - Using a C program inside of Rails

Hi,

I have a compiled c program I use to do text processing.

It operates as a pipe:

cat sometext.txt | /usr/local/bin/my_c_program > othertext.txt

I want to use it to process text which is typed into
a textarea field in an HTML form.

What are some options I have to make use of this
executable so I could use it as a text filter inside
of Rails?

Try Kernel#popen [http://corelib.rubyonrails.org/classes/IO.html#M001289].

I''m writing tests and want to move my development data into my test  
db. I do a "rake db:data:dump MODEL=My_modelname" and get a fixtures  
file that looks like this:

--
- !ruby/object:My_modelname
   attributes:
     name: nil
     notes:
     id: "1"
     state:
- !ruby/object:My_modelname
   attributes:
     name: rdfadd
     notes:
     id: "2"
     state:
.
.
.
etc

This format is rejected by the fixtures() method. To get it to work I  
have to take four (!) manual steps:

- erase the leading "--" line
- erase the "- !ruby/object:My_modelname" lines
- erase the leading double-space before "attributes"
- give each fixture record a unique name

So when I''m done it looks like this:

rec_1:
     name: nil
     notes:
     id: "1"
     state:
rec_2:
     name: rdfadd
     notes:
     id: "2"
     state:


I thought the whole point was the the dump makes YML files that can  
go straight into testing? Am I doing something wrong?

Thanks!
