Re: How install django in windows

[Swaroop Shankar V]

Hello Anuradha,

If you do a google search there are lots of tutorials covering this
information all over net. Basically you first need to install python
version < 3. Install python pip.  Make sure that the windows environment is
properly configured.  Then from your cmd type pip install django. Django
should be installed.

The above steps are just an overview of the installation. If you require
more details i would suggest you checking out:
https://code.djangoproject.com/wiki/WindowsInstall

If you have an option to install Linux,  then I would suggest you to use
linux for django development. Its very easy to setup and configure django
on a linux than on a windows machine.

Thanks and Regards,
Swaroop Shankar V

Re: Ecommerce Solution

Hi All,
I was checking out different option and found django-oscar interesting and
it is frequently updated too. Have anyone tried it out? What is your take
on that project? Is it worth a try?

Mario, is it possible to integrate LFS with an existing django project?
Also is there any method to import the data from my existing satchmo
installation to LFS?

Re: Ecommerce Solution

[Swaroop Shankar V]

Thanks Alex for your suggestion. I went through the documents for
django-shop and i could see that they are not directly supporting some
features like variation, payment gateway etc. Even if i plan to write the
plugins for that myself, I would like to know if there is any method to
import data from my existing satchmo installation.

Re: Ecommerce Solution

Hi Alec,
Cartridge is the one you mean I guess, but after going through the document
it seems i will require to install Mezzanine too. I was looking for an app
which i can use with my existing project and also with some good
documentation.

Thanks and Regards,

Ecommerce Solution

[Swaroop Shankar V]

Hi All,
Previously I had asked similar question on this group and decided to go
with Satchmo. After the implementation it turned out to be bit difficult to
maintain since the system do not provide much plugin or customization
support. So am thinking of implementing another ecommerce solution. The
system am looking for is an app which I can use with my existing site. Also
It would be better if the system would support a mechanism to migrate the
existing data from satchmo. I checked few but almost every project lacks
proper documentation. So is there any django ecommerce project that have
good documentation and easy to integrate?

Thanks and Regards,

Swaroop Shankar V

Re: Storing Sorl-thumbnail created images in separate folder

[Swaroop Shankar V]

It looks like the latest version of solr-thumnails or the version that i
have currently installed supports THUMBNAIL_STORAGE. When i checked i could
see a file under the path solr/thumbnail called defaults.py. In this file
there are following options

DEBUG = False
BASEDIR = ''
SUBDIR = ''
PREFIX = ''
QUALITY = 85
CONVERT = '/usr/bin/convert'
WVPS = '/usr/bin/wvPS'
EXTENSION = 'jpg'
PROCESSORS = (
'sorl.thumbnail.processors.colorspace',
'sorl.thumbnail.processors.autocrop',
'sorl.thumbnail.processors.scale_and_crop',
'sorl.thumbnail.processors.filters',
)
IMAGEMAGICK_FILE_TYPES = ('eps', 'pdf', 'psd')

which i guess can be overridden from the django settings file. Here there
is BASEDIR and SUBDIR and i guess those are the settings to be used but not
sure. When i tried to override the default i could see no change. So anyone
having experience in setting the same please let me know.

Thanks and Regards,

Swaroop Shankar V

Storing Sorl-thumbnail created images in separate folder

[Swaroop Shankar V]

Hello All,
I am using sorl-thumbnail extensively in my project. It works perfectly
fine except for one issue which is regarding the storage. The default
behaviour of sorl-thumbnail is to create the images in the same folder
where the original image is stored. Is it possible to provide
a separate location for storage of generated file rather than the source
folder? I could find a setting called THUMBNAIL_STORAGE, is it the one to
be used? I am not able to figure it out from the documentation. If yes then
should i provide the absolute or relative path?

Thanks and Regards,

Swaroop Shankar V

Re: URL regex not matching

[Swaroop Shankar V]

Thanks a lot for your reply. I just found an regex from some blog which is
as follows

(r'^user/([\w\'\.\-]+\s?[\w\'\.\-]+)/$','accounts.views.userProfile'),

and this seems to be working fine. Have not tested all the use cases for
this regex, but anyway username with . (dot) is working fine now.

URL regex not matching

[Swaroop Shankar V]

Hello All,
I need some urgent help with this one. Am trying to show a user profile
when the user navigates to a url of this format

http://example.com/user/

I have provided the following expression in my urls.py file

(r'^user/(\w+)/$','accounts.views.userProfile'),

this working fine for normal usernames, but if the user add a . (dot) in
between his username the url do not match with the regex and throws Page
not found error.

Since the django username supports  Letters, digits and @/./+/-/_  i want
all these to be supported in my url. Could someone please help me to
construct the url. Am pretty weak in regex and it will take me sometime to
build a proper regex for the above url. Thanks

Regards,

Swaroop Shankar V

Re: Admin area hyperlinks to sub categories

[Swaroop Shankar V]

Hi Sandro,
Thanks for the link. It looks like you had provided the link to show
additional options in the action drop down on the list page. This is not
what am exactly looking for. I guess my question was not clear. I will try
to explain it in much better way:
1) I have 2 models called Categories and Books. The book have a foreign key
to Categories model, which means more than one book can be marked under a
category.
2) The user is presented with a Category link on the admin dashboard
3) When the user clicks on to it he is taken to a page where all the
Categories will be listed
4) The categories listed will be an hyperlinks
5) When the user clicks on to any one of the category then he is redirected
to another listing page where all books under that category will be
displayed. So if the cartegory is fiction then all the books which are
assigned under fiction will be displayed.

So how can i link a category to book listing page. I know that there is a
filter method that i can use in books listing page but i want to implement
above said approach. How can it be done? I hope i have made myself clear.

Thanks and Regards,

Swaroop Shankar V

Improving Site Performance

[Swaroop Shankar V]

Hi All,
Am developing a site using django and it is almost ready to be launched.
Right now am trying to optimize the performance of the site. I have
installed the django debug toolbar and when i checked the number of queries
being exicuted on the homepage i could see there are 74 queries
being executed. On debugging I could see that most of the queries  are
through the context_instance=RequestContext(request) that am passing to a
view. When I removed it I could see the queries where reduced to 24, which
improved the performance, but I end up in an error

Caught KeyError while rendering: 'request'

this is happening because the homepage is rendering a custom template
tag which requires the request object available (to access the
currently logged in user details). So is there any way to avoid using
context_instance=RequestContext(request) and still make the request
object accessible in the custom template tag?

Thanks and Regards,
Swaroop Shankar V

Doubt regarding endless pagination

[Swaroop Shankar V]

Hi All,
This question is regarding a django app called endless pagination. I want
to add a '|' in between the pagination numbers so that it will look like
<>

I went through the documents but could not figure out how to do this. If
anyone have already implemented something like this please tell me know the
method to implement the same. Thank You

Regards,

Swaroop Shankar V

Re: problem with admin settings

[Swaroop Shankar V]

Sophia,
I created a project, and tired your settings.py file on that project. Did a
syncdb and everything is working perfectly fine at my end. As i said before
it looks like due to some reason the django_session table is not getting
created at your end. Instead of running syncdb from pycharm environment try
to do that from the terminal and check if that table is being created or if
there are not much important code in your project just zip it and send
over. Will try at my end and will update you.

Thanks and Regards,
Swaroop Shankar V

Re: Trouble setting up website with mysql as backend

[Swaroop Shankar V]

Hello Clifford,
It was really nice of you to provide an insight into the non strict mode. I
agree to what you said regarding the length of the field. I was developing
the project using sqlite and since it was ready to go live i wanted to test
it using mysql in my local system. When i ran syncdb i was getting the
above said error and just for the sake of testing i changed the mode to non
strict. Am not planning the same for my production server. Once again
thanks a lot for your input. Cheers.

Thanks and Regards,

Swaroop Shankar V

Re: problem with admin settings

Did you run the syncdb after enabling it? While doing a syncdb did you
encounter any errors? From the error it looks like django_session table is
not created.

Please check if you have enabled the app 'django.contrib.sessions' in

Re: Trouble setting up website with mysql as backend

Sithembewena,
Its not because i have not installed mysql module for python. syncdb worked
fine for many of the apps in my project and created the tables for those
apps. This issue arise when creating the table for few apps.

As you can see its a mysql warning since i had changed mysql mode to non
strict. The error from the traceback looks to be from the
file 
"/usr/local/lib/python2.7/site-packages/django/contrib/auth/management/__init__.py"
which is django contrib application. What should i do to fix this issue. Am
using django version 1.3.1. Please help.

Re: Selecting an E-commerce Application

[Swaroop Shankar V]

Thanks all, I decided to use plata for my project, since I feel it can be
customized for my requirement much better than the other E-Commerce project
(i might be wrong but still after evaluating most of the django ecommerce
project this is what i felt). Matthias, thanks for developing Plata. Just
starting the integration of Plata in my project and I hope you would lend
some help if i get struck somewhere :) Thanks

Confused with django model Limit and Offset Implementation

[Swaroop Shankar V]

Hi,
Am trying to create a custom pagination for my project, but am seriously
struck with the django implementation of Limit and offset. I went through
the documents, instead of making me understand how it works, i ended up
more confused. So suppose I have a page limit of 3 records per page and if
i want to load the second set of records how should the following statement
be?

Data = NewsFeedStory.objects.order_by('-updated_on')[?:?]

and similarly if i want to load the 3rd set with same page limit, how
should the same statement be? I played with the django shell to figure out
how this works but am still confused. Please help.

Thanks and Regards,

Swaroop Shankar V

Selecting an E-commerce Application

[Swaroop Shankar V]

Hello All,

I need to integrate an e-commerce application into my project and i was
checking few options and I rounded of to 2 options:
1) Satchless <http://satchless.com>
2) Plata <https://github.com/matthiask/plata>

Please note that I don't wish to use a framework, instead i wanted an app
which i can integrate into my existing django project. If anyone have used
these before, please recommend which one I should use. Or is there any
better e-commerce app?

Thanks and Regards

Joining tables

[Swaroop Shankar V]

hello All,
I have a model of following structure

class ExtraInfomration():

user = models.OneToOneField(User)
total_likes = models.IntegerField(_('Total Likes'), null=True, blank=True,
default=0)
total_dislikes = models.IntegerField(_('Total Dislikes'), null=True,
blank=True, default=0)
popularity = models.FloatField(_('Popularity'), null=True, blank=True,
default=0.0)
created_on = models.DateTimeField(auto_now_add = True, null=True)
updated_on = models.DateTimeField(auto_now=True)

I have another model for profile. I need to retrieve users ordered by the
popularity from the User model. This is the code am using to retrieve the
users list
userObject = User.objects.filter(is_active=1,is_staff=0,is_superuser=0)

how can i order the data based on the popularity field in extrainformation?
Thanks

Re: Removing Save functionality from Admin

Hi All,
I guess the question was not clear and am sorry for that. I have a model by
the name Photos. I have enabled the admin section for this model.
I don't want the admin to create any entries for this models from the admin
area, so i need to remove the 'Add Photos' button on top of the Photos
listing page. How can it be done? Hope my question is much more clear now.
Thanks

Re: Joining Tables

Thanks Jonas, the statements you had provided would give me a list of users

Actually I was looking for a single statement which would join all these
tables and returns the data based on the Group ID.

Joining Tables

[Swaroop Shankar V]

Hi,
I got a models which is as follows:

class Photos(models.Model):
"""
This model will enable the users to upload photos
"""
user = models.ForeignKey(User)
title = models.CharField(_('Title'), max_length=250, null = True, blank
= True)
description = models.TextField(_('Description'), null = True, blank =
True)
image = models.ImageField(_('Image'), upload_to=get_image_path)
created_on = models.DateTimeField(auto_now_add = True)
updated_on = models.DateTimeField(auto_now = True)

The user field is a foreign key to django auth User model. Each user is
assigned to a group (django Auth Group model). I want to retrieve all the
photos which belongs to users of a specific group. How can it be done?

Thanks and Regards,

Swaroop Shankar V

Facebook like activity feed commenting using django comments framework

[Swaroop Shankar V]

hello All,
Am trying to build somewhat like an activity stream for my web application.
Since its not exactly similar to the normal activity streams found in
facebook I am not able to use any of the existing django activity stream
projects like django-activity-stream in my application. So I am building it
from scratch. I would like to make use of the django commenting system for
commenting on each post that show's up on the activity steam. Since i would
like to use ajax to post comments, I will require an API, using which I can
save the comment posted to the commenting system framework table. I looked
through the documentation but could not figure out how i can do it. If
someone have any experience in doing the same please let me know the
procedures.

Thanks and Regards,
Swaroop Shankar V

Copying and Writing EXIF information from one file to another

[Swaroop Shankar V]

Hi,
Am trying to copy the exif information to the resized image of the same
image using pyexiv2. Searching for a solution i stumbled upon a post in Stack
Overflow<http://stackoverflow.com/questions/400788/resize-image-in-python-without-losing-exif-data>.
It looks like the api's used in the function is outdated and is not
available in the latest version. Based on the latest document i created a
function like this

def write_exif(originFile, destinationFile, **kwargs):
exifInformation = get_exif(originFile)
metadata = pyexiv2.ImageMetadata(str(destinationFile))
for key, value in exifInformation.iteritems():
metadata[key] = value

metadata.write()

def get_exif(file):
"""
Retrieves EXIF information from a image
"""
ret = {}
metadata = pyexiv2.ImageMetadata(str(file))
metadata.read()
info = metadata.exif_keys
for key in info:
data = metadata[key]
ret[key] = data.raw_value
return ret

But this ends up in an error


Python argument types in
_ExifTag._setParentImage(_ExifTag, NoneType)
did not match C++ signature:
_setParentImage(exiv2wrapper::ExifTag {lvalue},
exiv2wrapper::Image {lvalue})


I am now clueless on what went wrong. Could someone please help me out?
Thanks

Referring to same model records as a parent

[Swaroop Shankar V]

Hi,
I am trying to implement a menu system for my project which would enable
the admin to create menu's that will be displayed on the webpage. So i
should be able to create sub-menus which will have a parent menu. My table
structure will be as follows

id
name
url
parent_id

Here the parent_id will be the id of the menu of the same table. So on the
admin area i want a select box for the parent_id which will display the
already entered records. How can it be done?

Re: How to do some additional process while saving a django flatpage

[Swaroop Shankar V]

Well Daniel, I tried this but i am not able to see the function being
called while saving any flatpage page. Is it possible to give me a step by
step instruction on how to achieve the same? I read through the signals
documents but i am kind of confused on where to include the signal related
statements since the document do not give much details about it. I am still
not able to completely understand the signal's system in django. So I would
request for a step by step instruction, if its possible. Thanks

Help Required with Image Upload

[Swaroop Shankar V]

Hello All,
Am pretty new to Django. I am trying to create a form which will upload an
image and then enable the user to crop visually (using JCrop plugin). Am
not completely sure on how to implement this in Django. I am thinking of
first saving the uploaded image into the disk as a jpeg file and then load
and display the image as an overlay where the user can crop the image. I am
able to create a form with the image field and then am passing over
request.FILE to a function called handle_uploaded_image. Following is
my handle_uploaded_image function

def handle_uploaded_image(self, image):
"""
This function is to handle uploaded image file
"""
imageFile = Image.open(StringIO.StringIO(image.read()))
fileName = hashlib.md5(imageFile.getvalue()).hexdigest()+'.jpg'

Now i am kind of confused on how to convert the uploaded image into jpg
using PIL, and then saving into the disk. I had defined a field in my model
to save the image file name which is as follows:

class UserProfile(models.Model):

avatar = models.ImageField(_('Avatar'),upload_to=settings.IMAGE_UPLOAD_PATH,
null=True)

I did this based on the django documentation, but it tells something about
binding the form which am not able to correctly understand. Why do we need
to bind a form with image field. Also whats the use of giving upload_to in
model image field? Thanks in advance for any help.

Regards,

Swaroop Shankar V

Image Field Issue

Hello All,

I am having a trough time with the Image Field. I am trying to upload an
image and even if i upload a valid image, the form validator throws an error
"Upload a valid image. The file you uploaded was either not an image or a
corrupted image.". I have verified that PIL is installed in my system, even
then its showing this validation error. I have not done any processing as
such. In my models.py i have the following statement:
avatar = models.ImageField(_('Avatar'),upload_to=settings.IMAGE_UPLOAD_PATH,
null=True)

where IMAGE_UPLOAD_PATH is set to 'uploads/images' which i guess should be
in my MEDIA_URL. Then in my forms.py i have the following statment:
avatar = forms.ImageField(label=_('Avatar'))

I am not sure if i have done something wrong. Please guide me. Thanks

Setting default values in a form from DB table

[Swaroop Shankar V]

Hello All,

I am trying to create a Edit form to edit user information. I would like to
display the default values in the form fields rendered and am getting the
values from the db table. I can take an approach by creating a dictionary
with the values that needs to be populated in the form fields in my view
file and then pass it to the html. Then in the html, i can manually set the
values using the django-widget_tweaks. But the problem here is that there
are few select box for which this approach wont work. So the next option is
to do it from the forms.py but there i need to get the currently logged in
user and since request object is not available i created an __init__
function with the following statements

def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
super(UserEditForm, self).__init__(*args, **kwargs)

but now i am not sure on how to set up the form values. My form's class code
can be accessed via the url http://pastebin.com/1TuRmNhH . Please help.

Thanks and Regards,
Swaroop Shankar V

Re: How to do some additional process while saving a django flatpage

[Swaroop Shankar V]

Hello Phang,

Thanks for your reply. Well the requirement is like when ever a page is
created i want to save an entry into the menu table to. This is to be an
automatic process. If i understand correctly, the method you suggested will
require a manual process or a cron running to fetch the data from the
flatpage table and then enter it into my menu table. So is there any way to
make it an automated process?

Thanks and Regards,

Swaroop Shankar V

Re: Django Registration extra fields not getting saved

[Swaroop Shankar V]

Hello Sébastien,

Thanks for your response. I just figured out the issue. Actually signals was
not getting called. The reason was that the django-registration was not
installed properly. Actually i copied the django-registration folder to my
project folder instead of the normal installation. Once i went for a normal
installation signals worked just fine.

Thanks and Regards,

Swaroop Shankar V

How to do some additional process while saving a django flatpage

[Swaroop Shankar V]

Hi,
I am trying to build a menu system which can be controlled at the admin
area. For the content management purpose i am using django flatpage. So when
a page is getting saved i need to insert the page title and url in the menu
table i have created. So i guess a flatpage signal is the best way to go,
but after searching a lot i could not find any such signals available for
flatpage. So which is the best approach to implement whatever i had
described above. Thanks
Regards,

Swaroop Shankar V
