Not sure if I'm doing to much work here and something in ActiveLDAP would be more efficient, but I need to have an indexed list of LDAP objects once they have been retrieved as I will eventually be dealing with several thousand entries.  So I am putting the data into a Hash.



def course_list_search(course_filter)
  puts "Course Search:"
  Course.search(
    :base => 'ou=courses,dc=wiu,dc=edu', :filter => course_filter,
    :scope => :sub,
    :attributes => ['cn','wiuCourseDays','wiuCourseEndDate','wiuCourseInstructor','wiuCourseLocation','wiuCourseNumber','wiuCourseSection','wiuCourseStartDate','wiuCourseTime','wiuCourseTitle','wiuStarNumber']
  )
end


courses = course_list_search('wiuStarNumber=3167*')
  course_hash = Hash.new
  courses.each do |course|
    course_hash[course[0]] = course[1]
  end
  puts course_hash.size

course_hash.each do |val|
    puts val.inspect
    puts val[1]["cn"]
    exit
  end



So I'm getting a Hash now with the object DN as the index and all the attribute values I am returning as a Hash of attributes => values.


>>>OUTPUT OF ABOVE
Course Search:
7
["wiuStarNumber=31673,ou=Courses,dc=wiu,dc=edu", {"cn"=>["ELED470"], "wiuCourseNumber"=>["470"], "wiuCourseStartDate"=>["20080825"], "wiuCourseTime"=>["08-00-12-00"], "wiuCourseLocation"=>["ARR"], "wiuCourseEndDate"=>["20081031"], "wiuCourseTitle"=>["SENIOR FIELD"], "wiuCourseSection"=>["003"], "wiuStarNumber"=>["31673"], "wiuCourseDays"=>["' MTWTF '"]}]
ELED470
<<<<

But maybe I'm doing too much work and the data I get back from LDAP in the "courses" object is already an indexed Hash?  I've compared the output of courses[0].inspect with the output in the loop where I do the 'puts val.inspect' and it looks identical.  However...when I get the output of courses.class and then course_hash.class, the first is type Array, not Hash as the second one is.  So am I doing too much work...or is this what I should be doing?

Thanks,
Matt

I'm sorry but I can't understand what you want to expect.
What is your expected result?
Should courses be a Hash?

I'm needing the LDAP query which returns a list of objects....that query is returned to "courses"...I need that to be a Hash with the indexes being the object DNs and the values being arrays of object attributes.

The way I have it in my code, converting the "courses" object to "course_hash" seems to be working.  I just didn't know if ActiveLdap already did that and whether I was overcomplicating it.

Unless you suggest a better solution, what I have seems to be working.

Thanks,
Matt

Did you try ActiveLdap::Base.find?

 courses = Course.find(:all,
   :base => 'ou=courses,dc=wiu,dc=edu',
   :filter => course_filter,
   :scope => :sub,
 )
 courses.each do |course|
   p course.dn
   p course.cn
   p course.wiu_course_days

I have no problems iterating through the list of objects....but I need to be able to reach into the list with the specific DN that I am looking for...


find_dn = 'cn=111111,ou=courses,dc=wiu,dc=edu'
course_I_want = courses.fetch(find_dn) #fetch this indexed item from the Hash


So 'courses' has to be a Hash.  So if ActiveLdap won't naturally return a Hash I have to convert what it is returning to a Hash (which I have been able to do).

If I'm doing it wrong let me know, but what I've coded seems to be working.

Thanks,
Matt

What about this?

course_you_want = Course.find(find_dn,
    :base => 'ou=courses,dc=wiu,dc=edu',
    :filter => course_filter,
    :scope => :sub,
 )

Do you need a course list too?

I thought about doing it that way except that when this application goes live I'll be searching multiple times for each course (once for every student who is enrolled) and there's 6000+ courses.  So I could be slamming the LDAP server with 10s or 100s of thousands of these single object queries.  That's why I thought I'd just run one big query

>>>pseudocode
Course.find(ALL_COURSES_FOR_FALL_2008)

....grab all the courses with their attributes and put the data into a Hash....then I just have to fetch from the Hash each time I need to retrieve info for a course.  Except for the initial query for ALL the courses and then putting that data into a Hash...I'm thinking this will be much faster plus the load on the LDAP server will only be for a short period of time while it finishes that one big query(in my testing it takes about 10 minutes).  The program will run early in the morning so impact on the users should be negligent....I just am trying to go easy on the LDAP server.  :)

Thanks,
matt

Subject: [Ruby-activeldap-discuss] Integer attribute where nil should be
	valid
Message-ID: <48B88E10.5050509@verizon.net>

First of all thanks for all the hard work on this gem.  I'm in the final 
stages of converting my rails sqlite based app over to open ldap (75+ 
models) and the activeldap gem has been working great!  I'll probably be 
shooting off a few emails with questions on some challenges I'm having 
and some work around that I've done.  Here's the first one:

One item that I have run in to is validation on integer fields.  I have 
a number of integer attributes in my schema where nil is a valid 
condition, for example a user could set x=5 and then go back and un-set 
it.  When these attributes are submitted through the rails app to 
active-ldap they fail the validation for valid integer.

To get around this issue I've modified the validate_normalized_value 
method in the Integer class found in syntaxes.rb to treat blank as 
valid.  This seems to be working as expected - when nil is sent to 
openldap for an integer attribute the attribute is removed from the 
entry, which is perfect for me.  I'd appreciate any feedback on this 
approach and also like to know what others are doing for cases like this?

NOTE: I haven't checked all other types, but char and DN seem to work 
fine with nil

thanks,
ted

I couldn't reproduce the problem. (I used sambaPwdLastSet
attribute in samba.schema.)

It seems that nil value is not validated by classes in
lib/active_ldap/schema/syntaxes.rb because
ActiveLdap::Validations#validate_ldap_values in
lib/active_ldap/validations.rb skips nil value.
