ENOUGH TALKING

LET GET TO WORK

LADIES AND GENTLEMEN

Start your project, by using the command
django-admin startproject projectname

You should see the content in the new folder
__init__.py manage.py settings.py urls.py

CONFIGURE IT A LITTLE

The settings is in settings.py we start with the database
find the similar template in settings.py
** show settings.py
http://gist.github.com/376201

A LITTLE MORE

here find the line in settings.py
find the same similar in settings and change it accordingly
** show template_dirs

PHEW.....

Now we can start working,

after we
python manage.py startapp issues

Now we really can start working
btw you should see the following

__init__.py models.py tests.py views.py

WHILE WE AT IT

Lets get a enable admin page in urls.py
change the part in settings.py
**show settings.py


and urls.py
**show urls.py

WHO WANT TO BE A MODEL?

model.py == database table (almost)
copy into models.py
**shows issues models

SETUP A APP

now save the models.py

add application in settings.py

this is just part of settings.py
**show example

create in issue/admin.py
**show admin.py


SYNC IT!!!!

Now we can create a database,

python manage.py syncdb

python mange.py runserver

**show admin page

FIRST SUBMIT A FORM

One cool aspect of django is you can automate form generation,
free with validation!!!!

create this one in issue/forms.py
** show form.py


NOW TO VIEW THE APPS

lets create django views

add the following
**show add view
**show item view
**show list view

TEMPLATING

Django uses template to present to user, let start with a main
template, and the template for app

** show base.html
** show add.html
** show view.html
** show list.html

URL.PY

now lets create a url to point to the webapp
create this one
** show issue/urls.py

modify from the template
** show urls.py
and demo

EXTRA!!!!

NOW A REVIEW OF HAYSTACK

FINDING NEEDLE IN HAYSTACK

Haystack is a search api for django, it support several backend,
including solr, whoosh,

A LITTLE SETUP(AGAIN)

Let do a little setup

git clone http://github.com/toastdriven/django-haystack.git

**show changes in settings.py

**show search_index

TELL HAYSTACK WHICH NEEDLE

We create a search index

** show search index

** search document place on
<template dir>/search/indexes/issue/issue_text.txt

NOW TELL SOLR

Create solr index, and run index

create a schema.xml for solr
python manage.py build_solr_schema > schema.xml

create search index
python manage.py rebuild_index

NOW CREATE A SEARCH SITE

We just reuse the search view
** show urls.py
add (r'^search/',include("haystack.urls"))

and create a template
** show search/search.html

VOILA!!!

Now we have a basic search.

except haystack can do quite a lot, which is another story
altogether
