I met this problem (Django base.py: 'str' object is not callable) when I go through a Django tutorial:
photo/models.py: - from django.db import models
-
from django.contrib.auth.models import User
-
from django.contrib import admin
-
-
class Album(models.Model):
-
title = models.CharField(max_length=60)
-
public = models.BooleanField(default=False)
-
def __unicode__(self):
-
return self.title
-
-
class Tag(models.Model):
-
tag = models.CharField(max_length=50)
-
def __unicode__(self):
-
return self.tag
-
-
class Image(models.Model):
-
title = models.CharField(max_length=60, blank=True, null=True)
-
image = models.FileField(upload_to="images/")
-
tags = models.ManyToManyField(Tag, blank=True)
-
albums = models.ManyToManyField(Album, blank=True)
-
created = models.DateTimeField(auto_now_add=True)
-
rating = models.IntegerField(default=50)
-
width = models.IntegerField(blank=True, null=True)
-
height = models.IntegerField(blank=True, null=True)
-
user = models.ForeignKey(User, null=True, blank=True)
-
-
def __unicode__(self):
-
return self.image.name
-
-
class AlbumAdmin(admin.ModelAdmin):
-
search_fields = ["title"]
-
list_display = ["title"]
-
-
class TagAdmin(admin.ModelAdmin):
-
list_display = ["tag"]
-
-
class ImageAdmin(admin.ModelAdmin):
-
search_fields = ["title"]
-
list_display = ["__unicode__", "title", "user", "rating", "created"]
-
list_filter = ["tags", "albums"]
-
-
admin.site.register(Album, AlbumAdmin)
-
admin.site.register(Tag, TagAdmin)
-
admin.site.register(Image, ImageAdmin)
photo/views.py: - from django.http import HttpResponseRedirect, HttpResponse
-
from django.shortcuts import get_object_or_404, render_to_response
-
from django.contrib.auth.decorators import login_required
-
from django.core.context_processors import csrf
-
from django.core.paginator import Paginator, InvalidPage, EmptyPage
-
from django.forms import ModelForm
-
from settings import MEDIA_URL
-
-
from dbe.photo.models import *
-
-
def main(request):
-
"""Main listing."""
-
albums = Album.objects.all()
-
if not request.user.is_authenticated():
-
albums = albums.filter(public=True)
-
-
paginator = Paginator(albums, 10)
-
try: page = int(request.GET.get("page", '1'))
-
except ValueError: page = 1
-
-
try:
-
albums = paginator.page(page)
-
except (InvalidPage, EmptyPage):
-
albums = paginator.page(paginator.num_pages)
-
-
for album in albums.object_list:
-
album.images = album.image_set.all()[:4]
-
-
return render_to_response("photo/list.html", dict(albums=albums, user=request.user,
-
media_url=MEDIA_URL))
Main urls.py: - from django.conf.urls.defaults import patterns, include, url
-
-
-
-
# Uncomment the next two lines to enable the admin:
-
-
from django.contrib import admin
-
-
admin.autodiscover()
-
-
-
-
urlpatterns = patterns('',
-
-
# Examples:
-
-
# url(r'^$', 'SoEasy.views.home', name='home'),
-
-
# url(r'^SoEasy/', include('SoEasy.foo.urls')),
-
-
-
-
# Uncomment the admin/doc line below to enable admin documentation:
-
-
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
-
-
-
-
# Uncomment the next line to enable the admin:
-
-
url(r'^admin/', include(admin.site.urls)),
-
url(r"", "main"),
-
)
I really hope someone could help me solve the problem! Thanks!
