urlpatterns = patterns('',
# Example:
# (r'^blog/', include('blog.foo.urls')),
(r"^admin/", include("django.contrib.admin.urls")),
(r"^pro/book/$", "blog.blogapp.views.bookentry"),
)

but when i am running in browser http://127.0.0.1:8000/admin its
giving me error
File "/usr/lib/python2.4/site-packages/django/core/servers/
basehttp.py", line 277, in run

Re: Admin form

[Praveen]

Hi Sadeesh,
first of all i thank you for reply me..
Sadeesh i tried your code but again i am getting module error
Traceback erro:
  File "/usr/lib/python2.4/site-packages/django/core/urlresolvers.py",
line 132, in _get_callback
raise ViewDoesNotExist, "Could not import %s. Error was: %s" %
(mod_name, str(e))

ViewDoesNotExist: Could not import admin.site. Error was: No module
named admin.site
when i manually checked again then there i get one folder named admin
within contrib and that is folder so we can import the folder itself
so i saw that file inside sites folder then i tried to import like
from django.contrib.sites import admin but again same error..
Thanks

Re: time help (again)

[Praveen]

Before getting the value you must check of its types which type is you
can not find the difference between DateObject-StrObject so you have
to have same kind of datatype
second thing open your terminal write python
>>import datetime
>>help(datetime)
which will list you all the function.
there is one function strftime() to format your date.
so you can discard nanoseconds
>>result=date1-date2

[Praveen]

Yeah you are right

depending on my DB you may or may not be allowed to do a LIKE
comparison on that, try doing an exact match

Dates don't really 'contain' or 'start with'.
that doesn't really make sense, I can do lookups against the year
month or day by doing, __year, __month, or __day respectively
Dates aren't strings, unless (cough) you're in sqlite.

Access records from two tables

[Praveen]

Models.py

class Listing(models.Model):
  name = models.CharField(max_length=20)
  description = models.TextField(max_length = 100)
  website = models.URLField()
  category = models.ForeignKey(Category)

class Category(models.Model):
  category_code = models.CharField(max_length = 50, primary_key=True,
blank=False)
  category_name = models.CharField(max_length = 50,)
  def __unicode__(self):
return self.category_code

i have cat_list.html which list all the category with name only as
link if some one wants to know more details he/she may click on that
link.

urls.py

(r'^category/category_view/$','mysite.library.views.categories'),
(r'^category/category_view/(?P\w+)/
$','mysite.library.views.category_info'),

views.py

def categories(request):
result_category = Category.objects.all()
return render_to_response("cat_list.html",
{'result_category':result_category})

def category_info(request, category_code):
result_category = get_object_or_404(Category, pk = category_code)
->result_listing = get_object_or_404(Listing, pk = id)
print result_category
return render_to_response("category_view.html",
{'result_category':result_category,'result_listing':result_listing})

see -->result_listing in category_info function. i want to display
some info of Listing tables of corresponding category_code.

when i use

1--> result_listing = get_object_or_404(Listing, pk = id) then i get
an error
id() takes exactly one argument (0 given)

2--> result_listing = get_object_or_404(Listing, pk = category_id)
then i am not getting the exact result cause Category(category_code)
is checking with Listing(id). it should check with category_id of
Listing tables.

i do not know how may i access corresponding records from two tables.

Change the url

return render_to_response("list_listing.html", {'report_list' :

{% endfor %}
  
 {% else %}
   No names found

  {% endif %}
  

I am displaying Listing_channels and Listing on same page. if some one
click on any Listing_channels the corresponding Listing must display
on same page. that is why i am also sending the Listing_channels
object to list_listing.html page. if some one click first time on
Listing_channels it shows the url http://127.0.0.1:8000/category/listing_view/1/
but second time it appends 1 at the end and the url becomes
http://127.0.0.1:8000/category/listing_view/1/1

I am trying to display like frameset left side all channels and right
side description of that channel.

Re: Change the url

[Praveen]

Hi Malcolm i am very new bie of Django. i read through
get_absolute_url but do not know how to use.
What you have given the answer i tried with that and its working fine
but my senior asked me what will happen if i change the site name then
every where you will have to change url
mysite.library.views.listing_view.

so they told me to use get_absolute_url

i wrote get_absolute_ul in models.py
def get_absolute_url(self):
return "/listing/%i/" % self.id
and i am trying to use in my html page template but i don't know how
to use

 {{n.list_channel}}

then again same problem. first time when some one click on link it
works fine but second time it appends the link like
http://127.0.0.1:8000/category/listing_view/3/3

Please give me some idea

Re: Change the url

[Praveen]

Hi Briel i am totally confused now.
My senior told me to write get_absolute_url

so i wrote get_absolute_url like this
class Listing_channels(models.Model):
list_channel = models.CharField(max_length = 20)
visibility = models.BooleanField()

def __unicode__(self):
return self.list_channel

def get_absolute_url(self):
return u'/category/listing_view/%i/' % self.id

and in html template i am calling

{%if listing_result %}
{% for n in listing_result %}
 {{n.list_channel}}
{% endfor %}
{% else %}
not available
{% endif %}


so its working fine.

so now i have two mechanism one is your as you told me to write and
second one is
get_absolute_url() function.

Now my confusion is if we have another same class event_channel and
event and many more classes like this then i will have to write
get_absolute_url() for each class
and if go with you then there i need to change only in urls.py that i
think fine.

so i should go with get_absolute_url? give me the best and solid
reason so i could make understand to senior, and you know the senior
behave..

Re: Change the url

[Praveen]

Hi Briel again my senior gave me other idea and they gave me a nice
reason why they want me to use get_absolute_url()

Given our new understanding of what the best practice is, the workflow
for a template designer, who shouldn’t need to know or understand
programming, is:

   1. Ignore the documentation’s preference for {% url %} and use what
makes sense in a given circumstance.
   2. In order to know what makes sense in a given circumstance,
figure out whether the view you want to link to is an object detail
view or not.
   3. If it’s an object detail view, use get_absolute_url.
   4. If not, dig through the Python code to find the friendly name
your programmer has given to the view you want to link to. You’ll want
to look at URL configurations for this. Please note that these URL
configurations may be strewn across many apps, including some third-
party apps that don’t reside in your project at all. Just read the
Python import statements in your base URL configuration and you should
be able to find them. Don’t know what a Python import statement or a
base URL configuration is?
   5. Once you’ve found the friendly name, read the regular
expressions in the URL configuration to figure out what arguments need
to be passed to the {% url %} tag. It may help to find and read the
associated view function. I know you probably don't know Python or
regular expressions, but sometimes life is hard.
Construct your {% url %} tag. Use filters to parse data like dates and
times into the format expected by your view function. If the filter
you're looking for doesn't exist, you may need to write it. Except you
can't, because you don't know Python. Sorry about that.
Be very careful not to make any typos in your {% url %} tag, or you
will almost certainly face a NoReverseMatch exception, which will be
nonsense to you and very difficult to debug.

If you find yourself in a situation with designers who would have
trouble fully grasping all the steps you’ve outlined above (and that’s
no knock on the designers, that shouldn’t really be their main job),
then the job falls to the developer to make it simpler.

For the rest of the cases — namely, those where you’re dealing with a
name plus arguments and you’re going to be using it over and over (and
hence it’ll be tedious to write out a {% url %} call every time), your
friendly local developer can supply you with a shortcut in the form of
a method you can hit on an object, decorated with permalink, as often
happens with get_absolute_url.

It’s also worth noting that you can often simplify repetition within a
template by using one of the newer features of the {% url %} tag: in
the form {% url some_pattern_name arg1=foo,arg2=bar as some_url %}, it
sets the variable some_url for reuse.

So basically, to me, this comes down to developers and designers
working together to share information: designers explaining what they
need in terms of backend support, and developers explaining what
support they can provide and how to use it.


I think their points are also positive and now i am going to use
get_absolute_url().

LiveSearch

[Praveen]

Hi all, how may i apply LiveSearch as Djago official sites do.

So far i have tried.
I have created full-text index for Listing_channels
l=Listing_channels.objects.filter(list_channel__search='Bowling')
its working but i do not want to search for particular table.

some one suggested me to inherit all the table from base table or
apply search query on each table and combine the result. but this is
really awkward.

is there any other alternative way.

how may i write Recursion for this

[Praveen]

class Listing_channels(models.Model):
  list_parent_id = models.IntegerField(blank = True)
  list_channel = models.CharField(max_length = 20)
  visibility = models.BooleanField()
  index = djangosearch.ModelIndex(text=['list_channel'], additional=
[])

  def __unicode__(self):
return self.list_channel

  def get_absolute_url(self):
return u'%s' % self.list_channel

these are the records of list_channel

id   list_parent_id   list_channel
1   0 Top Menu
2   1 Sight Seeing
3   1 Real Estate
4   1 Shopping
5   1 Restaurants
6   2 Activities
7   2 Amusement park 1
8   2 Art Galleries
9   2 Museums
10   2 Parks
11   2 Tour operators
12   6 Bowling
13   6 Dinner Cruises
14   6 Diving
15   3 Developers
16   3 Orientation
17   3 Real Estate Agents
18   3 Relocation

I wanted to print like this for Sight Seeing see here
http://explocity.in/Dubai/sightseeing/activites/diving-sightseeing.html

i wrote in views.py

def latest_listing(request):
  listing_result = Listing_channels.objects.all().filter
(list_channel='Sight Seeing')
  for n in listing_result:
 print "N1.id : ", n.id
   if n.list_channel:
   qset=(
   Q(list_parent_id = n.id)
   )
level2 = Listing_channels.objects.filter(qset).distinct()
for n in level2:
   print "N2.id : ", n.id
   if n.list_channel:
   qset=(
   Q(list_parent_id = n.id)
   )
print "QSET : ", qset
level3 = Listing_channels.objects.filter(qset).distinct()
for n in level3:
   print "N3.id : ", n.id
   if n.list_channel:
   qset=(
   Q(list_parent_id = n.id)
   )
level4 = Listing_channels.objects.filter(qset).distinct()
  #sight_result = Listing_channels.objects.all().filter
(list_parent_id=6)
  print "Listing Result : ", listing_result
  print "Level2 : ", level2
  print "Level3 : ", level3
  print "Level4 : ", level4
  #print "Sight Result : ", sight_result
  return render_to_response('sight_seeing.html',
{'listing_result':listing_result,'level2':level2,'level3':level3})

its printing me well up to level2
Sight Seeing
  Activities
 ---
 ---
  Amusement park
  Art Galleries
  Museums
  Parks
  Tour operators

but for Activities(Level3) it returns me blank list.
I know what is the problem in level3 iteration it goes to last id and
there is no parent_id. but for 6,7,8 there is parent id.

my output is

N1.id :  2
N2.id :  6
N2.id :  7
N2.id :  8
N2.id :  9
N2.id :  10
N2.id :  11
QSET :  (AND: ('list_parent_id', 11L))
Listing Result :  []
Level2 :  [, , , , , ]
Level3 :  []
Level4 :  []


my query is how may i get the value for Level3.

Please do not suggest me to use django-tree or mptt.

some one told me to use recursion i do not know how to do?

if you look for a while you will come to know where i hang up.

Thanks

Re: how may i write Recursion for this

[Praveen]

Hi Malcolm

Thanks for reply.

whatever you said i do agree.

I do not have huge dataset. whatevere i have given the records in table
(See earlier message of this discussion) that is fixed not going to be
expand.
as you said i wrote Level3 inside Level2

def latest_listing(request):
listing_result = Listing_channels.objects.all().filter
(list_channel='Sight Seeing')
for n in listing_result:
   print "N1.id : ", n.id
   if n.list_channel:
   qset=(
   Q(list_parent_id = n.id)
   )
level2 = Listing_channels.objects.filter(qset).distinct()
for n in level2:
   print "N2.id : ", n.id
   if n.list_channel:
   qset=(
   Q(list_parent_id = n.id)
   )
   print "QSET : ", qset
   level3 = Listing_channels.objects.filter(qset).distinct
()
   for n in level3:
print "N3.id : ", n.id
if n.list_channel:
qset=(Q(list_parent_id = n.id))

level4 = Listing_channels.objects.filter(qset).distinct()
#sight_result = Listing_channels.objects.all().filter
(list_parent_id=6)
print "Listing Result : ", listing_result
print "Level2 : ", level2
print "Level3 : ", level3
print "Level4 : ", level4
#print "Sight Result : ", sight_result
#return render_to_response('sight_seeing.html',
{'listing_result':listing_result,'level2':level2,'level3':level3})
return render_to_response('sight_seeing.html',
{'listing_result':listing_result})

But even though my 'level3' list is empty.

here is my output

N1.id :  2
N2.id :  6
QSET :  (AND: ('list_parent_id', 6L))
N3.id :  12
N3.id :  13
N3.id :  14
N2.id :  7
QSET :  (AND: ('list_parent_id', 7L))
N2.id :  8
QSET :  (AND: ('list_parent_id', 8L))
N2.id :  9
QSET :  (AND: ('list_parent_id', 9L))
N2.id :  10
QSET :  (AND: ('list_parent_id', 10L))
N2.id :  11
QSET :  (AND: ('list_parent_id', 11L))
Listing Result :  []
Level2 :  [, , , , , ]
Level3 :  []
Level4 :  []


I tried in other way too

def latest_listing(request):
channels = Listing_channels.objects.all().filter(parent_id=0)
res={}
print channels
for channel in channels:
subchannels = getsubchannels(channel.id)
if subchannels:
for subchannel in subchannels:
#res[subchannel.list_channel]=[]
categorys = getsubcategory(subchannel.id)
if categorys:
result=[]
for category in categorys:
result.append(category.list_channel)
res[subchannel.list_channel]=result
print res
return render_to_response("Restaurants.html",
{'channels':channels,'result':result,'res':res})

def getsubchannels(channel):
channels = Listing_channels.objects.all()
for n in channels:
if n.list_channel:
qset = (
  Q(parent_id = channel)
)
subchannels = Listing_channels.objects.filter(qset).distinct()
return subchannels

def getsubcategory(channel):
channels = Listing_channels.objects.all()
for n in channels:
if n.list_channel:
qset = (
  Q(parent_id = channel)
)
subchannels = Listing_channels.objects.filter(qset).distinct()
return subchannels

Custom User Profile

Hi every one
I am using django-registration application which is working fine with

Oops... yeah Brian that i forgot to make it as a foriegn key to the
user table and that might be surprised without making foriegn key i
did not get any error even though my settings.DEBUG is true. but now i
made user field in MemberProfile but the same problem my form data is
not saving to foriegn key.

Please assume the user as foriegn key to the user table on same link

Associating content with multiple sites

[Praveen]

lets assume all in lowercase

expo/expoapp/models.py


class events(models.Model):
title = models.CharField(max_length = 50)
summary = models.CharField(max_length = 100)
description = models.CharField(max_length = 300)
event_type = models.ForeignKey(event_type)
start_date = models.DateField()
end_date = models.DateField()
contact_detail = models.CharField(max_length = 100)
booking_url = models.URLField(max_length = 50)
venue = models.CharField(max_length = 100, blank = True)
address = models.CharField(max_length = 100, blank = True)

foodie/foodieapp/models.py


class events(models.Model):
title = models.CharField(max_length = 50)
summary = models.CharField(max_length = 100)
description = models.CharField(max_length = 300)
event_type = models.ForeignKey(event_type)
start_date = models.DateField()
end_date = models.DateField()
contact_detail = models.CharField(max_length = 100)
booking_url = models.URLField(max_length = 50)
venue = models.CharField(max_length = 100, blank = True)
address = models.CharField(max_length = 100, blank = True)

we have same structure events class in both sites.
Both sites use the same events database, and an events is associated
with one or more sites
It lets the site producers edit all events -- on both sites -- in a
single interface (the Django admin).
so my doubt is:
Is it necessary to write events class in both application and if it is
not then where should i keep events class in which app. if it should
be in both sites then how may i proceed ahead?
If i keep events class in both models.py then i will face this problem
No, that would mean for app a and b you will get tables: a_eventtype
and b_eventtype.

TEMPLATE_DIRS = (

so in admin interface i have 3 apps eventsapp, expoapp, and foodapp.
when i write in terminal
:~/DJANGOPRJ/myproject/exposite$/ python manage.py shell
>>from myproject.eventsapp.models import *
Traceback (most recent call last):
  File "", line 1, in ?
ImportError: No module named myproject.eventsapp.models

because i am inside the exposite. i think we can keep the eventapp on
Django python path and may call any where. but i do not know how may i
keep..

Re: blank=True on Char/TextFields

[Praveen]

Hi Toby, you have not read properly the django docs.

Note that empty string values will always get stored as empty strings,
not as NULL.

only use null=True for non-string fields such as integers, booleans
and dates.

For both types of fields, you will also need to set blank=True if you
wish to permit empty values in forms, as the null parameter only
affects database storage.

Avoid using null on string-based fields such as CharField and
TextField unless you have an excellent reason.

null is purely database-related, whereas blank is validation-related.
If a field has blank=True, validation on Django’s admin site will
allow entry of an empty value. If a field has blank=False, the field
will be required.

but in your case you want to leave the field with no string then go to
back-end and change the value NULL to 'NOT NULL' to that field.

 this
work but do not save altered value to database and i tried with this
too
 i get
errors " this field is required"


Very first time if user have not created profile then account/profile
will redirect you to profile.html and will let you to save the
profile. if the user come back or write in browser accounts/profile
then it will redirect you to accounts/editprofile(user have already
profile) with edit_profile.html and all fields display the same value
as he enetered first time while creating the profile now suppose he
change the gender Male to Female and save profile then it takes you to
view profile but in view profile i still get gender female(because
that form is GET met

Database error

Something's wrong with your database installation. Make sure the
appropriate database tables have been created, and make sure the
database is readable by the appropriate user.

registration and profile must save at a time

[Praveen]

hi all i have one very intrested question when we write /accounts/
register/ then on browser i get 5 field
username,pwd,cnfpwd,firstname,lastname
but i want to add two more fields city, age on registration form.
i know i can use django-profiles to extend User and can save to
UserProfile
but i am not worried let the city, age save to UserProfile table.
i want the user should feel he is registering with site but mechanism
is we are saving registration and profile at a time.
if i write on browser
/accounts/register

User Name : TextField
First Name : TextField
Last Name : TextField
Password   : TextField
Confirm  : TextField
City: TextField
Age: DropDown

Click on Register
last two field is saving to UserProfile table and remain are saving to
auth_user.
in settings.py AUTH_PROFILE_MODULE = app_label.UserProfile
i am very much familiar with django-registration and django-profile
but it really wiered to display extra fields on Registration Form for
that we will have to customize the from django.contrib.auth.forms.

thanks

Re: registration and profile must save at a time

[Praveen]

Thank you so much Malcolm but to display extra fields on sign up we
will have to customize the django.contric.auth.forms then that form is
generated from the user models i am so much confused whether i will
have to add extra field in user model class or not but i do not want
change the structure of auth_user table. ok in a single line i want
django-registration and django-profile to be mingle in one form. could
you please suggest me link or idea.

How the current user logging-in first while registration.. you mean to
say after successfully registration the user must login automatically.

Re: newbie question: django-registration

[Praveen]

You should change the site domain name example.com to 127.0.0.1:8000
check in your django-site table.. http://www.example.com/accounts/activate/
637cd08106eea9b1139efd34a0fa79a5d7f90494/  for instance
http://127.0.0.1:8000/accounts/activate/

Re: how to use email instead of username for user authentication?

[Praveen]

You please check the satchmo package there they are using email as
username in satchmo-registration using
user=generate_id(email,firstname)

Re: Registration

[Praveen]

Before going to answer of your question i am really sure that you have
not read the docs of django-registration and django docs any
way

if you want to make it use django-registration(default) then install
it and write in settings.py 'registration'(below of your appname)
in your site url

 (r'^accounts/', include('registration.urls')),

now you need to create registration_form.html (you go to in
registration packages and see all the views they have mentioned there
required html page)

create a folder named 'registration' and put your
'registration_form.html' inside that.

first create a simple template with only plain html
and write their User name : {{form.user}}
Password : {{form.password1}}

Re: How to disable deletion af a model instance

[Praveen]

Hi, i do not know how its going to achieve but in my case.
For each payment entry i will add delete button and will disable the
default django admin interface.
Create a separate GroupProfile class
class GroupProfile(models.Model):
name = models.CharField(_('name'), max_length=80, unique=True)
group = models.ManyToManyField(Group, verbose_name=_('group'),
blank=True)
city = models.ForeignKey(city)
user = models.ManyToManyField(User)

class Meta:
verbose_name = _('group')
verbose_name_plural = _('groups')

def __unicode__(self):
return self.name

Create a group for instance do_delete and assign the permission to
delete the entry.
Now create an entry for GroupProfile for instance do_delete_group and
assign the user and do_delete to this group.

in payment view you can write this code

tc = GroupProfile.objects.all().filter(user=use)
gd= {}
for obj in tc:
n = obj.group.all()
for o in n:
 gd[o.name]=o.name
value = gd.values()
render the value to the template and check if the value exist then
show the delete button otherwise do not delete.
Thanks

Re: Record is not saving

[Praveen]

Thanks
Actually earlier i was passing instance of Phone
phoneform = PhoneForm(request.POST,instance=Phone.objects.get
(user=request.user))
but at very first time there was no record in Phone table
that is what i was getting the sql query is not matching
so i tried with
try:
userob = Phone.objects.get(user=request.user)
except Exception,e:
userob = None
if request.method == 'POST':
phoneform = form_class(request.POST, instance=userob)

and its working fine:

[Praveen]

Hi
I have one form in forms.py

class EmailForm(forms.Form):
recipient = forms.CharField(max_length=14, min_length=12,
widget=forms.TextInput(attrs=require))
message = forms.CharField(max_length=140, min_length=1,
widget=forms.Textarea(attrs={'cols': 30, 'rows': 5}))

and my site url is
admin.autodiscover()
urlpatterns = patterns('',  (r'^admin/(.*)',
include(admin.site.urls)),)

now i want it to be shown on admin interface

I tried so far
First attempt

from myapps.forms import EmailForm
class EmailAdmin(admin.ModelAdmin):
 form = EmailForm
did not work Exception Value:
'DeclarativeFieldsMetaclass' object is not iterable

Second attempt
and now i followed 
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_urls
but could not get help

class EmailAdmin(admin.ModelAdmin):
def my_view(self,request):
return admin_my_view(request,self)

def get_urls(self):
urls = super(SmsAdmin, self).get_urls()
my_urls = patterns('',(r'^my_view/
$',self.admin_site.admin_view(self.my_view)))
return my_urls + urls

def admin_my_view(request, model_admin):
opts = model_admin.model._meta
admin_site = model_admin.admin_site
has_perm = request.user.has_perm(opts.app_label \
+ '.' + opts.get_change_permission())
context = {'admin_site': admin_site.name,
'title': "My Custom View",
'opts': opts,
'root_path': '/%s' % admin_site.root_path,
'app_label': opts.app_label,
'has_change_permission': has_perm}
template = 'admin/demo_app/admin_my_view.html'
return render_to_response(template,
context,context_instance=RequestContext(request))
admin.site.register(EmailForm,EmailAdmin)

and when i run server and type on browser http://localhost:8000/admin
and hit enter button

Exception Value:
'DeclarativeFieldsMetaclass' object is not iterable

and second time just after first time when i again enter then it show
me the admin page but i can't see my EmailAdmin in admin intercae..

Just help me or suggest me any link.

Thanks

Re: How to find the file / directory which is hidden?

[Praveen]

There is not a big deal.
If you want to find the hiddend file on windos there is one command
attrib -h
for more info look at http://commandwindows.com/command2.htm and find
for "Changing file attributes with "attrib" "
for unix http://www.faqs.org/docs/securing/chap5sec62.html
you need to write and script to run these commands.
I just give you small example

import command
command.getoutput('ls')

which will list you all the dir(s) and file(s).

Praveen

Django custom authentication

[Praveen Madhavan]

Hello All,

 I am trying custom authentication with django, I wrote a class and 
filled it with the methods authenticate and get_user, I also added this 
authentication to the AUTHENTICATION_BACKENDS in settings.py file.

I have called my custom authenticate method and followed it up with 
login in my view.

Everything seems to work fine, is_authenticated returns true for the 
user after login, but the subsequent requests have request.user as 
anonymous, unable to figure out the reason, require your help


Thanks
Praveen.M

It is getting created, could it be the django version ? I am using django 
1.5 and I found few django openid apps not working on 1.5 .

Re: Django tables with check box and delete button

[Praveen Kumar]

Currently I have a listview and a bootstrap table that displays the number
of records. I had tried to use request.method POST, to get the list of
checked boxes and feed it back to the delete action. However I get an error
stating that 'POST is not allowed 405' and when I looked on the web,
somewhere it states that POST doesn't work with django listview.

So any examples on generating a table with checkboxes which gives ability
to delete multiple records using a delete button would be helpful!

Re: Can any one help me with this question

[Praveen Chaudhary]

Yes, Django migrations can work with Oracle 11.2 using the python-oracle
database driver. However, it's important to note that the python-oracle
package is not an official Oracle-provided driver. The official driver is
called cx_Oracle, which is widely used for connecting Django to Oracle
databases.

Here's an example of how Django migrations can work with Oracle 11.2 using
cx_Oracle:

1. Install the cx_Oracle package using pip:
 pip install cx_Oracle
2.Update your Django project's settings.py file to include the Oracle
database configuration:
 DATABASES = {
'default': {
'ENGINE': 'django.db.backends.oracle',
'NAME': 'your_database_name',
'USER': 'your_username',
'PASSWORD': 'your_password',
'HOST': 'your_host',
'PORT': 'your_port',
}
}

Replace the 'your_database_name', 'your_username', 'your_password',
'your_host', and 'your_port' with the appropriate values for your Oracle
database.
3.Define your Django models in the models.py file.
4.Generate and apply the migrations using Django's makemigrations and
migrate commands:

These commands will generate the necessary SQL statements based on your
models and apply them to the Oracle database.

Please note that the example assumes you have already set up Oracle 11.2
and have the necessary Oracle client software installed on your machine.

It's also important to ensure that your version of Django is compatible
with Oracle 11.2. Refer to the Django documentation and the documentation
of the cx_Oracle package for any specific requirements or considerations
when working with Oracle databases.

Remember to replace 'your_database_name', 'your_username', 'your_password',
'your_host', and 'your_port' with the appropriate values for your Oracle
database configuration.

Re: Can any one help me with this question

[Praveen Chaudhary]

Hi Annadatha,

I'm glad to hear that upgrading to Oracle 21c worked for you. As for your
question about working without migrations in Django, it's certainly
possible but it's important to understand the implication and trade-offs.

Django migrations provide a way to manage and apply changes to your
database schema over time, allowing for version control and easy deployment
of database changes. They help maintain data integrity and make it easier
to collaborate with other developers.

However, if you prefer not to use migrations, you can disable them in
django by setting the 'MIGRATIIN_MODULES' setting to an empty dictionary in
your projects settings.py file:

 MIGRATION_MODULES = {}


By doing this, you'll essentially disable the migration framework, and
Django won't generate or apply migrations. Instead, you'll need to manually
manage your database schema changes, which can be more error-prone and less
convenient, especially in collaborative projects.

Keep in mind the following considerations if you decide to work without
migrations:

1. Database schema management: You'll need to manually create, modify, and
delete database tables, columns, and other schema elements as needed. This
requires careful coordination and communication between developers working
on the project.

2. Data integrity: Migrations help ensure data integrity during schema
changes by providing a way to define and execute data transformations.
Without migrations, you'll need to handle data migrations and
transformations manually, which can be challenging and error-prone.

3. Deployment and version control: Migrations provide a structured way to
apply schema changes to your database during deployment. Without
migrations, you'll need to find alternative approaches for managing
database changes in different environments and version controlling those
changes.

Ultimately, the decision to use or not use migrations depends on your
specific requirements, project complexity, and team collaboration. If
you're working on a small, personal project with a simple schema and
limited changes, managing the database schema manually might be feasible.
However, for larger projects or teams, migrations can provide significant
benefits in terms of maintainability, collaboration, and data integrity.

I hope this helps you make an informed decision. Let me know if you have
any further questions!

Best regards

Apscheduler is not running multiple jobs

[Praveen Chaudhary]

Hello, everyone

I am using an apscheduler to schedule my job in a django project. here is
code

def start():
"""
The `start` function creates a report using a scheduler to generate and
send reports based on
specified sources and schedules.
"""
logger.info(f" Started creating report")

executors = {
'default': ThreadPoolExecutor(1)
}

scheduler = BackgroundScheduler(executors=executors, daemon=True)

sources, idx_list, job_schedules, triggers = generate_report()

for source, idx, job_schedule, trigger in zip(sources, idx_list,
job_schedules, triggers):
job_id = f"daily_report_job_{source.name}_{job_schedule.pk}_{idx}"
logger.info(f" Adding job with ID: {job_id}")

try:
scheduler.add_job(
generate_and_send_report_by_source_name,
trigger=trigger,
id=job_id,
args=[source],
replace_existing=True,

)
except Exception as e:
logger.error(f" Failed to add job with ID {job_id}: {e}")

try:
if scheduler.state == 0:
scheduler.start()
except Exception as e:
logger.error(f" Scheduler failed to start: {e}")


def generate_report():
"""

their job schedules,

else:
trigger = CronTrigger(
hour=job_schedule.hour,
minute=job_schedule.minute
)
triggers.append(trigger)
idx_list.append(idx)
job_schedules.append(job_schedule)

return sources, idx_list, job_schedules, triggers


here is the models.py
class JobSchedule(TimeStamp):

*the problem is when i create one source with two different job schedule
instance, apscheduler is adding only one job*


*here is my my log message:*
apscheduler.schedulerAdded job "generate_and_send_report_by_source_name" to
job store "default"




*but it works if i create two source instances with two different job
schedule instances. *


*What are the mistakes I am making? I have tried many times to solve this
issue but did not recognize what I am missing.*

How to send email from django without authenticate smtp server

[Praveen Chaudhary]

Hello everyone,

Basically, I want to send the email from django using smtp server. I have
my own smtp server domain host at port 25, but don't want to pass
EMAIL_HOST_USER & EMAIL_HOST_PASSWORD. I am using EmailMultiAlernatives to
send the html and file, I am unable to send email without EMAIL_HOST_USER &
EMAIL_HOST_PASSWORD

Thank you for your help.

Re: Run an application periodically on django

[Praveen Krishna R]

*If you are on Linux machine, you can use cron jobs to schedule the jobs.*
*
*
*When I faced such a problem what I did was, I created a view to update my
site with a secret Url. I have scheduled a cron job to call this url. So
when the view gets called (with "curl" command I'm correct), the site gets
updated. **I can call this url from a browser also, anytime. **There should
be definitely  better methods of doing this, like importing django to make a
standalone app or something?! I haven't tried it yet!*
*
*
*
*
*On djcelery, I think you need to configure RabbitMQ or something to work
with!? correct me Kenneth, if I'm wrong. *
