Re: Re: Massive import in Django database

Hi, John:
I think your code is right, except "Doc.object" should be "Doc.objects";

The following pseudo code maybe fater than what you write:

doc_map = {}
for each xml:
extract from the xml data -> mydoc_code, mydoc_text, myRelated_doc_codes
doc = Doc.objects.create(doc_code=mydoc_code, doc_text=mydoc_text)
doc_map[mydoc_code] = (doc, myRelated_doc_codes)
for (doc, rcodes) in doc_map.values():
for rcode in rcodes:
doc.related_doc.add(doc_map[rcode])
doc.save()

I have checked, It's okay;
The object have be cached in doc_map, and no need re-query related_codes for 
related_doc from database,  the speed should speed up.

With Regards.

Subject: Massive import in Django database
Hello everybody, 


I've fallen in love with Django two years ago and I've been using it for my job 
projects. In the past I found very useful information in this group, so a big 
thank you guys!


I have a little doubt.
I have to import in Django db (sqlite for local development, mySql on the 
server) about 1.000.000 xml documents.


The model class is the following:


class Doc(models.Model):
doc_code =  models.CharField(max_length=20, unique=True, primary_key=True, 
db_index = True) 

doc_text = models.TextField(null=True, blank=True) 
related_doc= models.ManyToManyField('self', null=True, blank=True, db_index 
= True) 



>From what I know bulk insertion is not possibile because I have a 
>ManyToManyField relation.


So I have this simple loop (in pseudo code)


for each xml:
   extract from the xml  date-> mydoc_code, mydoc_text, myRelated_doc_codes


   myDoc = Doc.object.get_or_create(doc_code = mydoc_code)[0]
   myDoc.doc_text = mydoc_text
   
   for reldoc_code in myRelated_doc_codes:
myRelDoc =  Doc.object.get_or_create(doc_code = reldoc_code )[0]
myDoc.related_doc.add(myRelDoc )


  myDoc.save()




I'm doing it right? Do you have some suggestions, recommendation? I fear that 
since I have 1.000.000 docs to import, it will take a lt of time, 
especially during the get_or_create routines


thank you in advance everybody!


John

Re: Change settings.DEBUG in response to a request's source

[Cal Leeming [Simplicity Media Ltd]]

Although I can't comment on your individual use case, it's better to enable
remote error collection using something like Sentry or BugSnag. Both also
support integration with other languages, such as JS, which is very handy
when tracking down front end problems. There are lesser alternatives such
as New Relic error collection (which ties in with their APM) and plain ol'
email, but these are both considered obsolete these days.

To answer your original question, I'd strongly advice against selectively
enabling debug, but if you insist then you'd probably want to do it inside
middleware. Naturally any errors that occur before the middleware is loaded
won't get caught and will display the standard 500, and this could include
quite a few different problems (e.g. Db connection failure). If any
libraries/modules cache the settings.DEBUG property prior to the middleware
being called, then this may cause some weird edge cases. Another
alternative is to do is based on IP, but again this is extremely bad
practice for production.

Hope this helps.

Cal

Re: NameError at /admin/ name 'HoleImage' is not defined

Understood, got that error cleared now.

Just a last question - should my HoleImages not present their upload 
options in the Hole part of the admin?

Change settings.DEBUG in response to a request's source

[Silas Snider]

I'm writing an app where it'd be super helpful for logged-in users from my 
company to see error pages and the like as though the app was running with 
DEBUG=True, while still preventing ordinary users from seeing that output. 
I see that the docs strongly warn me against changing settings at runtime, 
so I was wondering how I could achieve the same effect?

Thanks Ilya,

I will go through that this evening - I tend to learn through hardship, 
banging my head off the wall, walking away and finding a moment of clarity, 
I'm quick to understand the logic and approach but I leant the language /

Re: NameError at /admin/ name 'HoleImage' is not defined

[Patrick C]

Should it be this:

from django.contrib import admin
from holes.models import HoleImage

class HoleImageInline(admin.TabularInline):
model = HoleImage

class HoleAdmin(admin.ModelAdmin):
fields = ['hole_number', 'hole_name', 'hole_description']
list_display = ['hole_number', 'hole_name', 'hole_description']
inlines = [ HoleImageInline, ]

admin.site.register(Hole)
admin.site.register(HoleImage)



or this:

from django.contrib import admin
from holes.models import HoleImage

class HoleImageInline(admin.TabularInline):
model = HoleImage

class HoleAdmin(admin.ModelAdmin):
fields = ['hole_number', 'hole_name', 'hole_description']
list_display = ['hole_number', 'hole_name', 'hole_description']
inlines = [ HoleImageInline, ]

admin.site.register(Hole, HoleImages)


Still have errors trying either, sorry again for noob questions.

 Hi All,

 New to Django / Python (coming from PHP).

 Trying to make a site for a golf course where there is a hole by hole 
 guide, each hole has a number, name, description then multiple images for 
 the gallery.

 I've spend the last few hours googling how I'm going wrong here because 
 I get the error in the subject line.

 My models.py is:

 from django.db import models

 *class Hole(models.Model):*
 *hole_number = models.IntegerField()*
 *hole_name = models.CharField(max_length=255)*
 *hole_description = models.CharField(max_length=500)*

 *def __str__(self):*
 *return self.hole_number*

 *class HoleImage(models.Model):*
  *hole = models.ForeignKey(Hole, related_name='images')*
 *image = models.ImageField(upload_to='hole_photos')*
 *caption = models.CharField(max_length=250)*


 and my admin.py is:

 *from django.contrib import admin*
 *from holes.models import Hole*

 *class HoleImageInline(admin.TabularInline):*
 *model = HoleImage*

 *class HoleAdmin(admin.ModelAdmin):*
 *fields = ['hole_number', 'hole_name', 'hole_description']*
 *list_display = ['hole_number', 'hole_name', 'hole_description']*
 *inlines = [ HoleImageInline, ]*

 *admin.site.register(Hole)*


 Full admin panel error is:

 NameError at /admin/

 name 'HoleImage' is not defined

 will have a lesson learned as I 

RE: NameError at /admin/ name 'HoleImage' is not defined

[Ilya Kazakevich]

Hello,

I believe you should start with Python tutorial: 
https://docs.python.org/2/tutorial/ 
After you complete it, you may go to Django tutorial.

It is generally a good idea to study basic language concepts, syntax and 
standard library before studying any framework (you've learned PHP _before_ 
zend/phpcacke/joomla or wordpress, right?:) )

Oh and in the last line, admin.site.register, use the model you want to

When you import HoleImage don't remove Hole :)

Re: NameError at /admin/ name 'HoleImage' is not defined

[Patrick C]

Hi Jorge,

Thanks for helping out - I understand that and have just tried it but still 
get the error:

NameError at /admin/

name 'Hole' is not defined

Request Method:GETRequest URL:http://127.0.0.1:8000/admin/Django Version:
1.6.5Exception Type:NameErrorException Value:

name 'Hole' is not defined

Exception Location:/Users/my_laptop/development/golfsmart/holes/admin.py in 
, line 12Python Executable:/usr/bin/pythonPython Version:2.7.5

So just to clarify my structure incase I'm missing something on 
pluralisation:

holes
- admin.py
- model.py


*models.py:*

from django.db import models

class Hole(models.Model):
hole_number = models.IntegerField()
hole_name = models.CharField(max_length=255)
hole_description = models.CharField(max_length=500)

def __str__(self):
return self.hole_number

class HoleImage(models.Model):
hole = models.ForeignKey(Hole, related_name='images')
image = models.ImageField(upload_to='hole_photos')
caption = models.CharField(max_length=250)

*admin.py:*

from django.contrib import admin
from holes.models import HoleImage

class HoleImageInline(admin.TabularInline):
model = HoleImage

class HoleAdmin(admin.ModelAdmin):
fields = ['hole_number', 'hole_name', 'hole_description']
list_display = ['hole_number', 'hole_name', 'hole_description']
inlines = [ HoleImageInline, ]

admin.site.register(Hole)

In admin.py you have

from hotels.models import Hole

Add HoleImage to that import

Re: NameError at /admin/ name 'HoleImage' is not defined

[Patrick C]

Hi Ilya,

Thanks for the swift reply, sorry for the noob question but can you 
elaborate on "but you forgot to import HoleImage" - I'm not quite 
following, I'm sure I will understand it once explained.

I'm only about 4 hours into my first workings with Python / Django, perhaps 
I'm jumping in a little too quick but so far I have read through a fair bit 
and live the prose.

RE: NameError at /admin/ name 'HoleImage' is not defined

[Ilya Kazakevich]

To use any symbol (including " HoleImage" class) you need to import it first. 
You've imported Hole (from holes.models import Hole), but you forgot to import 
HoleImage.
So, you got " name 'HoleImage' is not defined " error.

It is better to use IDE, because it helps you in such cases :)

NameError at /admin/ name 'HoleImage' is not defined

[Patrick C]

Hi All,

New to Django / Python (coming from PHP).

Trying to make a site for a golf course where there is a hole by hole 
guide, each hole has a number, name, description then multiple images for 
the gallery.

I've spend the last few hours googling how I'm going wrong here because I 
get the error in the subject line.

My models.py is:

from django.db import models

*class Hole(models.Model):*
*hole_number = models.IntegerField()*
*hole_name = models.CharField(max_length=255)*
*hole_description = models.CharField(max_length=500)*

*def __str__(self):*
*return self.hole_number*

*class HoleImage(models.Model):*
*hole = models.ForeignKey(Hole, related_name='images')*
*image = models.ImageField(upload_to='hole_photos')*
*caption = models.CharField(max_length=250)*


and my admin.py is:

*from django.contrib import admin*
*from holes.models import Hole*

*class HoleImageInline(admin.TabularInline):*
*model = HoleImage*

*class HoleAdmin(admin.ModelAdmin):*
*fields = ['hole_number', 'hole_name', 'hole_description']*
*list_display = ['hole_number', 'hole_name', 'hole_description']*
*inlines = [ HoleImageInline, ]*

*admin.site.register(Hole)*


Full admin panel error is:

NameError at /admin/

name 'HoleImage' is not defined

Request Method:GETRequest URL:http://127.0.0.1:8000/admin/Django Version:
1.6.5Exception Type:NameErrorException Value:

name 'HoleImage' is not defined

Exception Location:/Users/my_laptop/development/golfsmart/holes/admin.py in 
HoleImageInline, line 5Python Executable:/usr/bin/pythonPython Version:2.7.5


As I say, I'm new to this and have had a good trial and error stab, I'm 
sure it's something simple I am overlooking and once I have it resolved I 
will have a lesson learned as I have a few other apps to setup that will 
use this many type for images.

Thanks in advance.

implementing a ticket submission system

[Anurag Baidyanath]

i am implementing a ticket submission system whose model.py file looks loke 
this:
class Ticket(models.Model):
user_id=models.ForeignKey(User)
category_id=models.ForeignKey(Category)
subject=models.CharField(max_length=100)
message=models.TextField(help_text="enter message")

i need to take the data submitted by the user(message and subject); and 
generate the ticket_id dynamically for each ticket. Then the data has to be 
saved into the database. please suggest an approach for this.

Re: Django and Javascript

[Cal Leeming [Simplicity Media Ltd]]

This is quite an open ended question, and touches on the subject of asset
pipelines.

This also touches on the whole debate around how JS applications should be
developed, libraries such as Ansible and Backbone may impact your
style/preference.

The closest library I've seen so far is django-pipeline, but it doesn't
have support for requirejs, there was also another discussion relating to
this topic [1].

For example, the rules of decoupling still apply, if the JS is not linked
to the site HTML in anyway (e.g. REST API) then you would ideally keep this
in a separate repo and use whatever asset pipeline suited you best. However
if your JS is closely coupled to your site HTML, then this would probably
stay inside your Django static.

It really depends on how complex your JS application is, for simple
requirements django-pipeline will do just fine. The best advice I can give
would be to research all the different options, and decide which is best
for your specific use case and tastes.

Hope this helps

Cal

Re: Massive import in Django database

[moqianc...@gmail.com]

Hi, John:
I think your code is right, except "Doc.object" should be "Doc.objects";

The following pseudo code maybe fater than what you write:

doc_map = {}
for each xml:
extract from the xml data -> mydoc_code, mydoc_text, myRelated_doc_codes
doc = Doc.objects.create(doc_code=mydoc_code, doc_text=mydoc_text)
doc_map[mydoc_code] = (doc, myRelated_doc_codes)
for (doc, rcodes) in doc_map.values():
for rcode in rcodes:
doc.related_doc.add(doc_map[rcode])
doc.save()

I have checked, It's okay;
The object have be cached in doc_map, and no need re-query related_codes for 
related_doc from database,  the speed should speed up.

With Regards.

Subject: Massive import in Django database
Hello everybody,


I've fallen in love with Django two years ago and I've been using it for my job 
projects. In the past I found very useful information in this group, so a big 
thank you guys!


I have a little doubt.
I have to import in Django db (sqlite for local development, mySql on the 
server) about 1.000.000 xml documents.


The model class is the following:


class Doc(models.Model):
doc_code =  models.CharField(max_length=20, unique=True, primary_key=True, 
db_index = True) 

doc_text = models.TextField(null=True, blank=True) 
related_doc= models.ManyToManyField('self', null=True, blank=True, db_index 
= True) 



>From what I know bulk insertion is not possibile because I have a 
>ManyToManyField relation.


So I have this simple loop (in pseudo code)


for each xml:
   extract from the xml  date-> mydoc_code, mydoc_text, myRelated_doc_codes


   myDoc = Doc.object.get_or_create(doc_code = mydoc_code)[0]
   myDoc.doc_text = mydoc_text
   
   for reldoc_code in myRelated_doc_codes:
myRelDoc =  Doc.object.get_or_create(doc_code = reldoc_code )[0]
myDoc.related_doc.add(myRelDoc )


  myDoc.save()




I'm doing it right? Do you have some suggestions, recommendation? I fear that 
since I have 1.000.000 docs to import, it will take a lt of time, 
especially during the get_or_create routines


thank you in advance everybody!


John

Re: Django and Javascript

[Cal Leeming [Simplicity Media Ltd]]

Have a look at how Stripe do it [1].

Stripe.setPublishableKey('YOUR_PUBLISHABLE_KEY');

I think this is what you're asking for (if I've understood your question
correctly).

Django and Javascript

[César García Tapia]

Hi.

Probably this is an old subject, and it's been argued lots of times, but I 
guess I need some help to find the right resources.

When building a real-world django application, you need javascript. Lots of 
it. Making JS talk to django is more or less easy: $.ajax(), 
django-rest-framework, and you're done. The problem comes when you need 
Django talking to JS. You need this variable initialized with some View 
context value, or init the i18n of that plugin with the {{ LANGUAGE_CODE 
}}, or whatever. There are a thousand cases that are on everybody's mind.

The obvious way is to add a 

Re: django installation

[Bill Freeman]

Still, the OP's command should have worked.  The most likely problem is
that Django was installed to a different python than the one  he gets when
he types "python" at the shell.  He does not say how he installed Django,
so it is hard to advise.

LiveServerTestCase modifies production database when ran in python script

[yakkadesign]

When I run my tests in a python script it modifies my production database.  
If I run from the command line it doesn't.  When I say modify, it wipes out 
my existing users and replaces them with the users I create for testing.  

I followed this for the setup: 
https://docs.djangoproject.com/en/1.4/topics/testing/#django.test.LiveServerTestCase
I created a  to setup users.  

When I run this the production database isn't modified:
  python2.7 manage.py test yPayment

In my python script I have:
  from django.utils import unittest
  class yPaymentTest(LiveServerTestCase)
  ...
  suite_payment = unittest.TestLoader().loadTestsFromTestCase(yPaymentTest)
  unittest.TextTestRunner(verbosity=2).run(suite_payment)

It might be worth comparing the SQL that Django generates versus what you

simple comparison?

[MikeKJ]

if userform.is_valid():
name = userform.cleaned_data['name']
email = userform.cleaned_data['email']
username = userform.cleaned_data['username']
password = userform.cleaned_data['password']
orgs = Organisation.objects.all()

#return render_to_response("userprofile/join_form.html", 
{'orgs': orgs, 'name': name, 'controls': controls, 'userform': userform, 
},context_instance=RequestContext(request))

for x in orgs:
if x.title == name:   
return render_to_response("userprofile/join_form.html", 
{'name': name, 'controls': controls, 'userform': userform, 
},context_instance=RequestContext(request))
else:
raise NameError("Missed")

This bit ... if x.title == name:   simple huh?

if I run the same in a shell,
 
>>> from directory.models import Organisation
>>> name = "ANORG"
>>>orgs = Organisation.objects.all()
>>>for x in orgs:
>>>if x.title == name:
>>>name

that works

if I uncomment the render to response and do it in the template,
   
{% for x in orgs %}
{% ifequal x.title name %}
 {{ x.title }}
{% endifequal %}
{% endfor %}

that works

but for the life of me I cant see why in the actual view it decides that 
there is no match and goes to the else, it shouldn't, it should find a 
match!!!

for that you have to learn what the code means.  "while x !=[]:" will
always be an endless loop.  the "[]" doesn't do what you think.

Your function doesn't modify "x", so "x != []" is always true. You created an 
endless loop which appends "y" until memory is exhausted. Hence the MemoryError.

These aren't Django-specific questions anymore, so you should head over to a 
Python mailing list to get further help with basic Python programming.

Massive import in Django database

[John Carlo]

Hello everybody,

I've fallen in love with Django two years ago and I've been using it for my 
job projects. In the past I found very useful information in this group, so 
a big thank you guys!

I have a little doubt.
I have to import in Django db (sqlite for local development, mySql on the 
server) about 1.000.000 xml documents.

The model class is the following:

class Doc(models.Model):
doc_code =  models.CharField(max_length=20, unique=True, 
primary_key=True, db_index = True) 
doc_text = models.TextField(null=True, blank=True) 
related_doc= models.ManyToManyField('self', null=True, blank=True, 
db_index = True) 

>From what I know bulk insertion is not possibile because I have a 
ManyToManyField relation.

So I have this simple loop (in pseudo code)

for each xml:
   extract from the xml  date-> mydoc_code, mydoc_text, myRelated_doc_codes

   myDoc = Doc.object.get_or_create(doc_code = mydoc_code)[0]
   myDoc.doc_text = mydoc_text
   
   for reldoc_code in myRelated_doc_codes:
myRelDoc =  Doc.object.get_or_create(doc_code = reldoc_code )[0]
myDoc.related_doc.add(myRelDoc )

  myDoc.save()


I'm doing it right? Do you have some suggestions, recommendation? I fear 
that since I have 1.000.000 docs to import, it will take a lt of time, 
especially during the get_or_create routines

thank you in advance everybody!

John

Re: Re: Django Python roop

[moqianc...@gmail.com]

In your function, if x is not a empty list,  then while will be a infinite 
loop, x always not be  [];
then the inner for-loop  will append many many items into y list, Then your 
computer will say "have the Memory Error",  to tell you the memory not enought.

Hah, it's almost definitely something silly -- have you added

No worries - post your urls.py and other things that maybe relevant when
you have access and we'll try and figure it out.

RE: Django Python roop

[Ilya Kazakevich]

Hello,

What are you trying to do? Split string? Copy array? You probably need to use 
builtin functions for that.

Re: Admin site doesn't work

[Glen J]

Sanjay,
Thanks for the reply.  I've tried accessing it various ways using both 
nginx and the included devserver on :8000.  I've done both 127.0.0.1/admin 
and 127.0.0.1/admin/ with the same results.  I can post the contents of my 
urls.py later today when I have access to my machine at home.  FWIW, I 
didn't think the example.com entry was the issue, but at this point I'm 
kinda grasping at straws as I've checked my urls.py and settings.py about a 
hundred times and synced with the database many times as well and don't get 
a hard error, only the django welcome page.

Re: Admin site doesn't work

[Sanjay Bhangar]

hey Glen,

Sorry if this is a silly question - but are you sure you are visiting
/admin on your site?
If you are and still getting this error, can you please paste the
contents of your urls.py

Django creates a default site called example.com. You are expected to
change this to your correct site URL when you deploy. This should not
be the cause of your troubles though - AFAIK, this is only used when
generating full url permalinks, like in RSS feeds, etc.

HTH,
Sanjay

Re: Admin site doesn't work

[Glen J]

I've tried it both on the development server you indicate below as well as 
on a my own web server (nginx using uwsgi) and get the same results.  No 
errors are displayed, simply the welcome page for Django.  Syncdb works 
fine (using Postgresql) and shows output when I do it.  One thing I did 
spot in the database that I wasn't sure of is in my django_site table it 
has example.com.  Not sure why it is there as I never did that.

If you think there's a bug in the tutorial, you should log a ticket in the 
ticket tracker and/or make a pull request. But you're going to need to be a 
bit more specific in explaining what exactly you think is wrong and why.

While this is technically correct, it is not good advice to give to a 
newbie. Experienced developers should be encouraging best practice among 
newcomers, and to be honest there really isn't a good reason *not* to use 
virtualenv.

Poll App part 3

[divyanshi kathuria]

In Django poll application part 3, url passed in index.html is 'detail'. I 
doubt it should be 'index'.

There is no need to install virtualenv to install Django.

Start python

'1.5.8'

... in my case

"ResourceWarning: unclosed" error using mysql-connector-python

[Zemian Deng]

Hi there,

I am using mysql-connector-python (1.1.6) with Django (1.6.5) and myapp is 
working fine. But each SQL call to DB will result the following warning 
messages:

Exception ignored in: 

ResourceWarning: unclosed 


Has anyone seen this and know a way to resolve it?
Also, FYI, I am using the following in my settings file.
DATABASES = {
'default': {
   'ENGINE': 'mysql.connector.django',
   'NAME': 'mydb',
   'USER': 'test',
   'PASSWORD': 'test',
},
}

Thanks,
Zemian

So i supposedly installed Django because on the terminal, after going

Re: Anyone interested in reviewing code for a hobby project - BookMarker

[trojactory]

Hi Aseem,

> Is there some other layout?

Yes. The current version of Django uses the layout mentioned in the 
tutorial itself: https://docs.djangoproject.com/en/1.6/intro/tutorial01/

> The second part about relative imports. I have never understood how 
relative imports work. I mean the syntax. I have went through the PEP to 
understand it and did a lot of google searches but that is something that I 
never got the hang of. Is there any specific reason that I should be using 
them?

Relative imports would continue to work even if your app or project name 
changes. They are also unambiguous as mentioned in the docs 
.

> Would you like to use an app that won't autocomplete?

I think the confusion was caused by your flat-style project layout. There 
is a distinction between a Django project and an app. I was referring to 
adding too much functionality into a bookmarking *app*. It is perfectly 
fine in a project though.

Cheers,
Arun
