Hi!
I am going Django (liking it so far), and I seem to hit a wall with
one of the exercises. It likely because of my unfamiliarity with
Python, so bear with me, please.
At the end of Hour 6, I got two exercises to do:
1. Create an additional view for the People object that displays the
Blog contents for a specific Person.
2. Create an URL pattern in the URLConf that collects the Person's ID
from the URL request and passes it to the view function that you
created in Exercise .
So this is the code I have so far:
url.py:
from django.conf.urls.defaults import *
details1 = {'opts':('name','email')}
details2 = {'opts':('name','birthday')}
details3 = {'opts':('name','desc','favoriteURL')}
details4 = {'opts':('name','blogs')}
urlpatterns = patterns('iFriends.People.views',
(r'^$','index'),
(r'^Info/$','details'),
(r'^Info/(?P<pID>\d+)/$', 'details'),
(r'^Contact/(?P<pID>\d+)/$','details', details1),
(r'^Birthday/(?P<pID>\d+)/$','details', details2),
(r'^Details/(?P<pID>\d+)/$','details', details3),
(r'^Blog/(?P<pID>\d+)/$','blog_details', details4), # This is the one
I have problems with
)
The view that I created:
def blog_details(request, pID='0', opts=()):
response = HttpResponse()
response.write("<HTML><BODY>\n")
try:
b = Person.objects.get(id=pID)
for d in opts:
response.write("<li>%s: %s</li>" % (d,
b.__dict__[d]))
except Blog.DoesNotExist:
response.write("Blog Not Found")
response.write("</BODY></HTML>")
return response
These are the models that I am working with:
from django.db import models
from django.contrib.auth.models import User
gender_list = (('M','Male'), ('F', 'Female'))
# Create your models here.
class Blog(models.Model):
title = models.CharField('Title', maxlength=200)
text = models.TextField('Text', maxlength=2048)
class Admin:
pass
class Person(models.Model):
userID = models.ForeignKey(User, unique=True)
name = models.CharField('name', maxlength=200)
birthday = models.DateField('Birthday',blank=True,null=True)
gender = models.CharField(maxlength=1, choices=gender_list)
email = models.EmailField('Email', unique=True)
headshot = models.ImageField(upload_to='img', blank=True)
favoriteURL = models.URLField('myURL')
favoriteBooks = models.ManyToManyField('self',blank=True)
favoriteMovies = models.ManyToManyField('self',blank=True)
desc = models.TextField('Desc',maxlength=500, null=True)
friends = models.ManyToManyField('self',blank=True)
blogs = models.ManyToManyField(Blog, blank=True)
def __str__(self):
return '%s' % (self.name)
class Admin:
pass
I am able to at least pass the parameters, that I know. That said, I
kept getting this:
AttributeError at /People/Blog/1/
'QuerySet' object has no attribute 'text'
Request Method: GET
Request URL: http://giggle.org:8000/People/Blog/1/
Exception Type: AttributeError
Exception Value: 'QuerySet' object has no attribute 'text'
Exception Location: /home/rilindo/iFriends/../iFriends/People/views.py
in blog_details, line 53
It is possible that I don't have a clear understanding on how to use
the ManytoManyField, but I could be wrong. At any event, It is
probably something simple that I am missing.
Help?
