[Zope] Reading File Contents

[Brokken, Allen P.]

I am working on a very simple "feedback" type form for my site.  I
realize this can be achieved with the collector or other intermediately
complex means, but for this site I need something very light weight and
simple.  All I need is a table of "Subject","Email address" to be read
from a file rather than hiding the values in the form.  Basically the
method that renders the form reads the file and picks up the subjects to
make a drop down, then when submitted it matches the subject to the
appropriate email address.  If it's not a valid subject it drops the
request, and only sends email to the right person.  If this were perl on
a traditional web server I would have done this in like 60 seconds.  As
it is I can't figure out how to read in the data from the text file so
it goes into an array properly.  I was hoping it might be as simple as
doing

 

file_name

subject1,email1 at host.com

subject2,email2 at host.com

subject3,email3 at host2.com

 

method

 

... Form header and fields

<select>

 

<dtml-call file_name>

<dtml-in file_name>

    <dtml-let keytosplit=sequence-item

         feedback_name="_.string.split(keytosplit, ',')[0]"

         email_address="_.string.split(keytosplit, ',')[1]">

         <option value="<dtml-var feedback_name>"><dtml-var
feedback_name></select>

  </dtml-let>

</dtml-in>

 

However it treats file_name as a string and won't let me <dtml-in> over
that.  Is there a way to easily convert the contents of the file to a
line by line input for a <dtml-in >statement, or some other quick and
dirty way to do this?  I've come up with some more complex ways with
adding a header character to each line to split on, with some form of
loop through it all, but turning the other file into a set for
<dtml-let> seems to be the most straight forward way to do it.

 

I've come up with half a dozen other ways to handle this that include
MySQL, or other products, but I really would like it to be as simple as
possible with as few external dependencies as possible.
