Your not thinking object oriented enough. Encapsulate, encapsulate,
encapsulate. :-)
Make objects of everything instead, and thank me later. :-)

Then you index the objects in a ZCatalog so you can do searches.

[Zope-dev] Trouble populating a dictionary of dictionaries

2002-09-05 Thread Anton Hughes 

Hi All,

I'm trying to implement a computer booking system for staff members here. At
the moment I have a table with date, timeslot (eg 8:00 - 9:00), resource
(eg. PC 1) and person. I want to draw a table showing the bookings for the
day looking something like this:

|Time| PC 1 | PC 2 | PC 3 |
++--+--+--+
|8:00|  AH  |  |  |
++--+--+--+
|9:00|  |  BC  |  MD  |
++--+--+--+  etc...

I thought the best way to do it would be use the table to populate a
dictionary of dictionaries like:

booking['8:00']['PC 1'] = 'AH'

Then when I'm rendering the table using ZPT I can use a nested loop to look
through the timeslots and resources and fill table cells with the
booking[slot][resource] value if it exists.

After playing around for too long on it, I can't seem to get it to work. I
even tried pre-filling the d-o-d with empty strings. I just don't understand
what I am doing wrong.

Thanks,

Anton

Code:
=

#parameters: booking_date
# Import a standard function, and get the HTML request and response objects.
from Products.PythonScripts.standard import html_quote
request = container.REQUEST
RESPONSE =  request.RESPONSE

bookings = {}   # declare the bookings dictionary
resource_hash = {} #declare the resource dictionary

#populate bookings dictionary with timeslot keys
for row in context.resources():
  resource = row['name']
  resource_hash[resource] = ''

#populate bookings dictionary with timeslot keys
for row in context.timeslots():
  slot = row['slot_name']
  bookings[slot] = resource_hash

#fill the bookings dictionary of arrays with actual bookings
for row in context.getBookings(on_date=booking_date):
 slot = row['timeslot']
 resource = row['resource'] - 1
 person = ['person']
 bookings[slot][resource] = person

return bookings

Hmmm. I posted code on the end of that message. I don't know what
happened to it. Anyway, I'll post the code here:

#parameters: booking_date
# Import a standard function, and get the HTML request and response objects.
from Products.PythonScripts.standard import html_quote
request = container.REQUEST
RESPONSE =  request.RESPONSE

bookings = {}   # declare the bookings dictionary
resource_hash = {} #declare the resource dictionary

#populate bookings dictionary with timeslot keys
for row in context.resources():
  resource = row['name']
  resource_hash[resource] = ''

#populate bookings dictionary with timeslot keys
for row in context.timeslots():
  slot = row['slot_name']
  bookings[slot] = resource_hash

#fill the bookings dictionary of arrays with actual bookings
for row in context.getBookings(on_date=booking_date):
 slot = row['timeslot']
 resource = row['resource'] - 1
 person = ['person']
 bookings[slot][resource] = person

return bookings

 Error Type: TypeError
 Error Value: unsupported operand type(s) for -

  resource = row['resource'] - 1

You should check that row['resource'] is a data type that supports
subtraction. If for example row['resource'] is a string, this will raise the
error. Try: resource = int(row['resource']) - 1

Thanks Andy,

 Error Type: TypeError
 Error Value: unsupported operand type(s) for -

  resource = row['resource'] - 1
  ^^^
That was pretty stupid of me. A hangover from my earlier attempt at a 2D
array :(
