solution to environment variable DJANGO_SETTINGS_MODULE is undefined
If you're playng with Django directly from Python, and not from Django's own manage.py shell, then you need to set the DJANGO_SETTINGS_MODULE variable before launching Python.
For example, if you have a Django project named "myproject", then run the following before launching Python:
export DJANGO_SETTINGS_MODULE=myproject.settings
For Apache to pick up that variable, you need to set it in httpd.conf as follows:
SetEnv DJANGO_SETTINGS_MODULE myproject.settings
Example:
saju@saju-pardus ~ $ export DJANGO_SETTINGS_MODULE=myproject.settings
saju@saju-pardus ~ $ echo $DJANGO_SETTINGS_MODULE
myproject.settings

AttributeError: 'NoneType' object has no attribute 'column'
Solution:
http://code.google.com/p/django-fts/issues/detail?id=5#c2
As a short-term fix, I removed `objects = fts.SearchManager()` from backends.SearchableModel, then added the
appropriate objects definition directly on my model, in the same way the docs tell you to if you want to define
which fields should be indexed.

How add 'read more...' link using django template filter truncatewords
How add 'read more...' link using django template filter truncatewords
I want to add a read more link if description contain more than 20 words
I am using filter truncatewords:20
I also want to hide read more... link , if words less than 20
solution:
{% ifnotequal foo foo|truncatewords:20 %}
<a href="...">Read more</a>
{% endifnoteuqal %}
The advantage this solution has is it works with truncatewords_html as well.
Example:
<p>
{{ note.description|linebreaks|safe|truncatewords:20 }}
{% ifnotequal note.description note.description|truncatewords:20 %}
<a class="readmore" href="{% url note_detail project.id note.id %}">read more...</a>
{%endifnotequal%}
</p>
------------
You can use the wordcount filter instead

introduction to psycopg
Python-PostgreSQL Database Adapter
psycopg is a PostgreSQL database adapter for the Python programming language. It was written from scratch with the aim of being very small and fast, and stable as a rock. The main advantages of psycopg are that it supports the full Python DBAPI-2.0, being thread safe at level 2 and providing some very usefull extensions like the user-defined type casters.
psycopg is different from the other database adapter because it was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a conspicuous number of concurrent INSERTs or UPDATEs. Every open Python connection keeps a pool of real (UNIX or TCP/IP) connections to the database. Every time a new cursor is created, a new connection does not need to be opened; instead one of the unused connections from the pool is used. That makes psycopg very fast in typical client-server applications that create a servicing thread every time a client request arrives.

import psycopg
dbh = psycopg.connect('dbname=dbname user=username')
print "Connection successful."
cur = dbh.cursor()
cur.execute("SELECT * FROM myTable")
rows = cur.fetchall()

python django datetime guide
Introduction
#-----------------------------
#introduction
# There are three common ways of manipulating dates in Python
# mxDateTime - a popular third-party module (not discussed here)
# time - a fairly low-level standard library module
# datetime - a new library module for Python 2.3 and used for most of these samples
# (I will use full names to show which module they are in, but you can also use
# from datetime import datetime, timedelta and so on for convenience)
import time
import datetime
print "Today is day", time.localtime()[7], "of the current year"
# Today is day 218 of the current year
today = datetime.date.today()
print "Today is day", today.timetuple()[7], "of ", today.year
# Today is day 218 of 2003
print "Today is day", today.strftime("%j"), "of the current year"
# Today is day 218 of the current year
Finding Today's Date
#-----------------------------
# Finding todays date
today = datetime.date.today()
print "The date is", today
#=> The date is 2003-08-06
# the function strftime() (string-format time) produces nice formatting
# All codes are detailed at http://www.python.org/doc/current/lib/module-time.html
print t.strftime("four-digit year: %Y, two-digit year: %y, month: %m, day: %d")
#=> four-digit year: 2003, two-digit year: 03, month: 08, day: 06
Converting DMYHMS to Epoch Seconds
#-----------------------------
# Converting DMYHMS to Epoch Seconds
# To work with Epoch Seconds, you need to use the time module
# For the local timezone
t = datetime.datetime.now()
print "Epoch Seconds:", time.mktime(t.timetuple())
#=> Epoch Seconds: 1060199000.0
# For UTC
t = datetime.datetime.utcnow()
print "Epoch Seconds:", time.mktime(t.timetuple())
#=> Epoch Seconds: 1060195503.0
Converting Epoch Seconds to DMYHMS
#-----------------------------
# Converting Epoch Seconds to DMYHMS
now = datetime.datetime.fromtimestamp(EpochSeconds)
#or use datetime.datetime.utcfromtimestamp()
print now
#=> datetime.datetime(2003, 8, 6, 20, 43, 20)
print now.ctime()
#=> Wed Aug 6 20:43:20 2003
# or with the time module
oldtimetuple = time.localtime(EpochSeconds)
# oldtimetuple contains (year, month, day, hour, minute, second, weekday, yearday, daylightSavingAdjustment)
print oldtimetuple
#=> (2003, 8, 6, 20, 43, 20, 2, 218, 1)
Adding to or Subtracting from a Date
#-----------------------------
# Adding to or Subtracting from a Date
# Use the rather nice datetime.timedelta objects
now = datetime.date(2003, 8, 6)
difference1 = datetime.timedelta(days=1)
difference2 = datetime.timedelta(weeks=-2)
print "One day in the future is:", now + difference1
#=> One day in the future is: 2003-08-07
print "Two weeks in the past is:", now + difference2
#=> Two weeks in the past is: 2003-07-23
print datetime.date(2003, 8, 6) - datetime.date(2000, 8, 6)
#=> 1095 days, 0:00:00
#-----------------------------
birthtime = datetime.datetime(1973, 01, 18, 3, 45, 50) # 1973-01-18 03:45:50
interval = datetime.timedelta(seconds=5, minutes=17, hours=2, days=55)
then = birthtime + interval
print "Then is", then.ctime()
#=> Then is Wed Mar 14 06:02:55 1973
print "Then is", then.strftime("%A %B %d %I:%M:%S %p %Y")
#=> Then is Wednesday March 14 06:02:55 AM 1973
#-----------------------------
when = datetime.datetime(1973, 1, 18) + datetime.timedelta(days=55)
print "Nat was 55 days old on:", when.strftime("%m/%d/%Y").lstrip("0")
#=> Nat was 55 days old on: 3/14/1973
Difference of Two Dates
#-----------------------------
# Dates produce timedeltas when subtracted.
diff = date2 - date1
diff = datetime.date(year1, month1, day1) - datetime.date(year2, month2, day2)
#-----------------------------
bree = datetime.datetime(1981, 6, 16, 4, 35, 25)
nat = datetime.datetime(1973, 1, 18, 3, 45, 50)
difference = bree - nat
print "There were", difference, "minutes between Nat and Bree"
#=> There were 3071 days, 0:49:35 between Nat and Bree
weeks, days = divmod(difference.days, 7)
minutes, seconds = divmod(difference.seconds, 60)
hours, minutes = divmod(minutes, 60)
print "%d weeks, %d days, %d:%d:%d" % (weeks, days, hours, minutes, seconds)
#=> 438 weeks, 5 days, 0:49:35
#-----------------------------
print "There were", difference.days, "days between Bree and Nat."
#=> There were 3071 days between bree and nat
Day in a Week/Month/Year or Week Number
#-----------------------------
# Day in a Week/Month/Year or Week Number
when = datetime.date(1981, 6, 16)
print "16/6/1981 was:"
print when.strftime("Day %w of the week (a %A). Day %d of the month (%B).")
print when.strftime("Day %j of the year (%Y), in week %W of the year.")
#=> 16/6/1981 was:
#=> Day 2 of the week (a Tuesday). Day 16 of the month (June).
#=> Day 167 of the year (1981), in week 24 of the year.
Parsing Dates and Times from Strings
#-----------------------------
# Parsing Dates and Times from Strings
time.strptime("Tue Jun 16 20:18:03 1981")

time.strptime("16/6/1981", "%d/%m/%Y")
# (1981, 6, 16, 0, 0, 0, 1, 167, -1)
# strptime() can use any of the formatting codes from time.strftime()
# The easiest way to convert this to a datetime seems to be;
now = datetime.datetime(*time.strptime("16/6/1981", "%d/%m/%Y")[0:5])
# the '*' operator unpacks the tuple, producing the argument list.
Printing a Date
#-----------------------------
# Printing a Date
# Use datetime.strftime() - see helpfiles in distro or at python.org
print datetime.datetime.now().strftime("The date is %A (%a) %d/%m/%Y")
#=> The date is Friday (Fri) 08/08/2003

Setting dynamic css class using filter in django
Setting dynamic css class using filter in django
=============================
How to set dynamic css class using filter in django
----------------------------- description
if you have a dict like { 'T': 'todo-type', 'ME': 'message-type' ...}
you can just use a filter like
timeline.type|timeline_type_class
which returns
timeline_type_map[timeline_type]
now
the next problem is
if you define this mapping near the filter
you know have two different places where the list of timeline types are kept
it will be easier to code if they are in a single place
so its better to place this in models.py
something like:
TYPE_MAP = [ ('M', ['Milestone', 'milestone-type']), ..... ]
then, you can generate the TYPE_CHOICES like this
[ (x[0], y[0]) for x,y in TYPE_MAP]
and you can generate the needed data for filter by doing
dict([ (x[0], y[1]) for x,y in TYPE_MAP])
we did all this code, simply for the reason that, we now have only a single place to edit, if we need to add more types
otherwise, we have to edit all over the place
------------------ in model
class Event(models.Model):
TYPE_MAP = [ ('TL', ['Todolist', 'todolist-type']),
('T', ['Todo', 'todo-type']),
('P', ['Project', 'project-type']),
('C', ['Category', 'category-type']),
('A', ['Activity', 'activity-type']),
('PM', ['Milestone', 'member-type']),
('MS', ['Mockupset', 'mockupset-type']),
('MU', ['Mockup', 'mockup-type']),
('M', ['Milestone', 'milestone-type']),
('MIC', ['Comment-Mi', 'milestone-comment-type']),
('ME', ['Message', 'message-type']),
('MEC', ['Comment-Me', 'message-comment-type']),
('TK', ['Ticket', 'ticket-type']),
('TKC', ['Comment-Tk', 'ticket-comment-type']),
]
TYPE_CHOICES = [(x, y[0]) for x,y in TYPE_MAP]
TYPE_ACTIONS = (
('A', 'Added'),
('U', 'Updated'),
('D', 'Deleted'),
('C', 'Completed'),
('R', 'Reassigned'),
('CL', 'Closed'),
)
type = models.CharField(max_length=3, choices=TYPE_CHOICES)
description = models.TextField()
created_on = models.DateTimeField()
done_by = models.ForeignKey(User)
project = models.ForeignKey(Project)
action = models.CharField(max_length=2, choices=TYPE_ACTIONS)
url = models.URLField()
objects = EventManager()
------------------ in tag file (/templatetags/filename.py)
@register.filter
def timeline_type_class(type):
#print dict(Event.TYPE_CHOICES)
type_choices = [(x, y[1]) for x,y in Event.TYPE_MAP]
for x in type_choices:
if type == x[0]:
return x[1]
------------------ in template
<ul>
{% for timeline in timelines %}
<li>
<span class="{{ timeline.type|timeline_type_class }} type">
{{ timeline.get_type_display }}
</span>
<span class="action">{{ timeline.get_action_display }} <a href="{{timeline.url}}">{{ timeline.description }}</a></span>
<span class="name">{{ timeline.get_action_display }} by {{ timeline.done_by }}</span>
</li>
{% endfor %}
</ul>
------------------ in css file
span.todo-type {
background-color: #C87800;
}
span.milestone-type {
background-color: #5F6E43;
}
span.message-type {
background-color: #334E7D;
}
span.comments-type {
background-color: #6493AC;
}
span.todolist-type {
background-color: #5493AC;
}
span.member-type {
background-color: #3493AC;
}
span.activity-type {
background-color: #8493AC;
}
span.category-type {
background-color: #6000AC;
}
span.mockup-type {
background-color: maroon;
}
span.mockupset-type {
background-color: orange;
}
span.project-type {
background-color: #AC7981;
}
span.ticket-type {
background-color: #107A81;
}
span.message-comment-type {
background-color: #BA7A81;
}
span.milestone-comment-type {
background-color: #CF7A11;
}
span.ticket-comment-type {
background-color: #CF0AA1;
}
span.type {
display: block;
float: left;
width: 70px;
text-align: right;
color: #FFFFFF;
padding: 2px 5px 2px 2px;
margin-bottom: 3px;
}
------------------ Note
1)
TYPE_CHOICES = [(x, y[0]) for x,y in TYPE_MAP] <------------
* This code create a list of touples.
* Type print TYPE_CHOICES to list of touples like below.
output look like:
[
('TL', 'Todolist'),
('T', 'Todo'),
('P', 'Project'),
('C', 'Category'),
('A', 'Activity'),
('PM', 'Milestone'),
('MS', 'Mockupset'),
('MU', 'Mockup'),
('M', 'Milestone'),
('MIC', 'Comment-Mi'),
('ME', 'Message'),
('MEC', 'Comment-Me'),
('TK', 'Ticket'),
('TKC', 'Comment-Tk')
]
2)
* Use dict() method to convert list of tuples to dictionary.
dict([(x, y[0]) for x,y in TYPE_MAP]) <------------
or
TYPE_CHOICES = [(x, y[0]) for x,y in TYPE_MAP]
dict(TYPE_CHOICES)
output look like:
{
'A': 'Activity',
'ME': 'Message',
'C': 'Category',
'TKC': 'Comment-Tk',
'MEC': 'Comment-Me',
'MIC': 'Comment-Mi',
'M': 'Milestone',
'MU': 'Mockup',
'P': 'Project',
'TL': 'Todolist',
'T': 'Todo',
'MS': 'Mockupset',
'TK': 'Ticket',
'PM': 'Milestone'

You can remove fields from templates (from html). They indeed should
be removed if you don't want them :)
Then we face a problem: some of CommentForm fields are marked as
required. The solution is to subclass CommentForm and set this flag to
False:
class NoEmailForm(CommentForm):
def __init__(self, target_object, data=None, initial=None):
super(NoEmailForm, self).__init__(target_object, data,
initial)
self.fields['email'].required = False

You can remove fields from templates (from html). They indeed should
be removed if you don't want them :)
Then we face a problem: some of CommentForm fields are marked as
required. The solution is to subclass CommentForm and set this flag to
False:
class NoEmailForm(CommentForm):
def __init__(self, target_object, data=None, initial=None):
super(NoEmailForm, self).__init__(target_object, data,
initial)
self.fields['email'].required = False
