oauth2 issue with Django + Google Analytics API integration

[Sithembewena Lloyd Dube]

Hi all,

I am converting a site from PHP to Python and pulling stuff from the Google
Analytics API using their new Python client library and oauth2. I'm having
an issue with oauth2 authentication where the redirect URI specified in my
client_secrets.json file is not recognised. The API seems to be redirecting
to localhost:8080/ when I specified a different URI.

After digging around for a bit, I got an error stating that I should run my
python script with the parameter --noauth_local_webserver as I am
developing on a remote machine using PuTTY.

This is mostly not a Django issue, but I thought to ask if anyone here has
ever had to do the same and encountered this?

Thanks.

Re: TinyMCE config

[Aljoša Mohorović]

documentation is not completely updated so steps in previous emails are correct.
i won't be available until next week but check second snippet under:
http://django-tinymce.readthedocs.org/en/latest/usage.html#the-flatpages-link-list-view

and be sure that you have something like:
"""
admin.site.unregister(FlatPage)
admin.site.register(FlatPage, TinyMCEFlatPageAdmin)
"""

free to open a ticket against the doc, from a quick check it seems that
none of the DB backends use the documented "SQL equivalent". (I wonder if
these documented "equivalents" are more trouble than they are helpful...)

Re: Issue Deploying Django

Agreed that virtualenv will allow you to install python packages - however 
not any linux/unix packages.  I have no problems using Django on Dreamhost.

Re: presenting a manytomany relationship in a tabular way

[goabbear]

Hi,
thanks for the links, I have look at these docs but I can't figure out how 
to mix actions with a spreadsheet like presentation :-/
Is it possible to create admin forms like we can standards forms?
Another way I could try is to use filter_horizontal (I like this 
presentation), but for a m2m relation, just 1 entity can be presented with 
this widget, not the other side, or I do something wrong?

Re: Issue Deploying Django

[JJ Zolper]

Yeah I've been looking into webfaction. Any information would be great
thanks William!

Only issues I would forsee is the root control. That is unless they have
all that I need but at the same time I think I would lean to having root
over not. Also I'm on a shared hosting right now and it's pretty good but I
might be ready to get more serious with my own box and what not.

Re: Issue Deploying Django

[JJ Zolper]

Yes when I saw no root privleges I realized very soon that I either have to
get a new host that has what I need installed or get my own box and full
control.

With virtualenv I can install the packages on bluehost?

 I had a feeling I would need it but I just like to be sure before I act.

 Another thing. On Ubuntu there were additional packages I had to
 install. I believe one was called "psycopg2-python-dev" or something like
 that.

 If I install psycopg2-python at:

 http://www.initd.org/psycopg/

 Are there any additional packges that I might need?

 I apologize for not being able to remember the additional ones I added
 before on Ubuntu but I'm at work and couldn't find in my installation
 history what they might have been or in my django google group discussions.

 I feel like one was called "libpq-dev" actually.

 Thanks for the help.

Re: How to print a graph

[Frank Stüss]

what exactly is your "error"?
Is your matplotlibrc correct?

If you will be using matplotlib maybe this example from an data
application i wrote may help you:

def calculate_myPic(my_args):
fig = figure(figsize=parameter.figsize)
plotarea = fig.add_subplot(111) # for my thing
# calculate your data
plotarea.bar(...) # eg. plot bars
plotarea.plot_date(...) # or a date based graph
title("my title" ) 
xlabel("ordinate") # eg. x-axis
# write it out on a png, *depending on matplotlibrc*
out = django.http.HttpResponse(content_type='image/png')
fig.savefig(out)
close()
return out

Demise of Mr. Kenneth Gonsalves

[Anoop Thomas Mathew]

With my heartfelt condolence, I'd like to inform you all the unfortunate
demise of Mr.Kenneth Gonsalves (KG - law...@thenilgiris.com), who was a
strong advocate of Python, Django and Free Software in India.
He had served as the President of IPSS(Indian Python Software Society),
which initiated the PyCon India, done a lot of workshops on Python and was
an active member in the Django user group.

Re: Issue Deploying Django

[Kurtis Mullins]

With Cloud Servers, yes -- you do get Root access. It's basically the
equivelant of a VPS that you can easily spawn, scale, and replicate as
needed.

Without root access on servers, virtual environments only get you so far.
What happens when you need to install Python imaging library but they don't
have a specific library? What happens when you decide you want to plugin to
some other library and the version of GCC they have is too ancient to
support its make system? etc These are just some examples of headaches
that may crop up without a good "open" system (such as a VPS, Cloud Server)
or a web host who explicitly supports Django.

DRYing up my forms.py

[Lee Hinde]

I have a lot of this throughout my forms.py files:


self.fields['verification_date'].widget.attrs["class"] = 'date-field
input-small'
self.fields['verification_date'].widget.format = '%m-%d-%Y'

self.fields['mail_response'].widget.attrs["class"] = 'date-field input-small'
self.fields['mail_response'].widget.format = '%m-%d-%Y'

self.fields['photo_response'].widget.attrs["class"] = 'date-field input-small'
self.fields['photo_response'].widget.format = '%m-%d-%Y'


is there a way to consolidate this sort of thing, such that if a field
is a date field, it always gets these settings without me having to
explicitly set them?

Well, you almost answered your own question. Subclass the DateField.

object.create speed, creating 3 objects takes 1 sec in sqlite

[Anton]

Hi I am new to Django.

I worked through the tutorial.

I created a small test app on:
 - Win7 64bit
 - python 2.7.3 (32bit)
 - Django 1.4.1
 - using the development server
 

Now I wanted to populate the (sqlite backend) database
with a python script.

My Problem:

I Insert 3 Object (like MyModel.objects.create(name="..", comment="..") ).

They consts only of 2 strings.

Inserting these 3 items take roughly 1 sec.

In settings.py I set DEBUG = False, but this doesnt help much
(I readed something about this on the net).

I retried with the mysql backend:
 -  mysql 5.5.27 (64bit)
 - using sockets (named pipe on windows)

Now the time varies between 0.2 sec and 0.8 sec every time
I insert suche a 3 object tripplet.


My Problem: I will populate it with 5 items.

Has Django really such a bad performance for data insertion?

I can't believe it, so ... can somebody give me a hint?
Is there a doc page dedicated to speed/performance issues??

Otherwise I have to look for an other system.

Thanks 

Anton

Re: TinyMCE config

[Jonathan Baker]

Success! Thanks for all the help. After integrating your app with the
FlatPage app I was able to integrate it with FlatBlock as well.

If you're up for it, I'd love to help update the documentation to save
future users (and yourself) some time with the issues I ran in to.

Thanks, that got me looking in the right place. I think I need to sublcass the 
widget, since I'm concerned with the display of the data, not how it's 
saved/stored?

Kenneth Gonsalvas (KG / lawgon) passed away on 3rd Aug 2012. He was leading
light, mentor, evangelist and practitioner of Free and Open Source
Software. He was a geek up to his last moments. His demise is a great loss
to FOSS Community in India. May his soul rest in peace.

A short bio of Kenneth Gonsalvas (Prepared by KG only)

"Although he has no formal training in the IT field, Kenneth Gonsalves has
been programming since 1986, starting with Turbo Pascal, then moving to
Perl and finally to Python in 2003. Since then he has focused on Python in
general and the Django web frame work in particular. He is an open source
enthusiast and has spoken and written on open source right from 1995 when
he was first introduced to it. He has conducted over 50 seminars and
workshops in python and Django. He was the founder president of the Indian
Python Software Society and a member of the team that has organised the
highly successful Indian python conferences from 2009 to 2011. He is now
based in Ooty where he writes and consults on open source. He also conducts
a job oriented course in python and django. His other main interest is golf
and he holds an international certification as a golf referee and has
refereed several national level golf tournaments. He writes a regular
column called 'Foss is fun' for the LFY monthly. Most of his code
contributions are here: http://bitbucket.org/lawgon/";

He was a good mentor and friend to many of us.

Thanks for the reply Melvyn. But after all this work and research
they've decided now that they want the popup displayed before the user
logs in. This greatly simplifies things, as I can do it all from the
login template. Thanks all for the help.

Sample Django template scrolling table

[Charles Norton]

I would like to create a simple table in a Django template that can scroll. 
I am interested in finding a sample from which I can learn. If someone 
would point me to a sample, I would appreciate it. 

The application would be having a 10 line table, 55 water meter information 
rows, and being able to scroll though the table back and forth.

Thanks.

Re: Sample Django template scrolling table

[Kurtis Mullins]

Can you clarify by what you mean when you say "scroll through the table
back and forth"?

This is pretty easy to implement using CSS/HTML and isn't relevant to
Django in particular -- but maybe I'm simply misunderstanding your question
:)

.filter(Q(childobj__attr1="something", childobj__attr2__gte=100)) and .filter(~Q(childobj__attr1="something", childobj__attr2__gte=100)) Don't Produce Opposite Results

[Matthew Kremer]

Having trouble figuring this one out.

class ParentObj:
id = UUIDField(primary_key=True)

class ChildObj:
id = UUIDField(primary_key=True)
parent = models.ForeignKey(ParentObj)
attr1 = models.CharField(max_length=128)
attr2 = models.IntegerField()

If you filter one table based on it's children tables parameters like so:

models.ParentObj.objects.filter(Q(childobj__attr1="something", 
childobj__attr2__gte=100)).count()

Let's say you get 1 and there are 10 total tables. Assuming that,

models.ParentTable.objects.filter(~Q(childtable__attr1="something", 
childtable__attr2__gte=100)).count()

Should return 9, however, it instead returns all ParentObjects that have AT 
LEAST ONE child where attr1 is not "something" and ALL children have attr2 
less than 100. It seems that the ~Q() does two seperate lookups on 
childtable for attr1 and attr2 instead of comparing both with one lookup.

Am I missing something?

Thanks,
Matt

can validate an email with .org address can register. I was wondering if 
someone could point me in the right direction in terms of how exactly I should 
modify the plugin. I am reading the docs and I see some forms for the default 
strategy. For example, there is one form disallowing the hotmail, gmail, etc. 
addresses. My strategy would be similar to that. However, since I am new to 
Django and Python, I don't know how I should modify the app. For ex., should I 
download a copy and put it in the main project folder? Any best practices and 
tips would be greatly appreciated.

Resubmit on error middleware

[Paul Pietkiewicz]

Hello All,

Is it possible to have a process_exception on handling an exception resubmit 
the request, instead of either returning a HttpResponse or None back to the 
user? Is there a clean way to redirect the response back to the view?

Thanks,
Paul

Re: object.create speed, creating 3 objects takes 1 sec in sqlite

[Kurtis Mullins]

If you plan to create a batch of objects, I wouldn't recommend going that
route. Instead, check this out:

https://docs.djangoproject.com/en/dev/howto/initial-data/

Has Django really such a bad performance for data insertion?


The Object Relational Mapper does quite a bit more than simply write SQL
insertion queries. I won't go into the details simply because I don't want
to run you in the wrong direction but if you're interested in that topic,
I'm sure someone else can fill you in on the details.

However, the main bottleneck that I see is in the structure. If you expect
5,000 queries at once on a regular basis then you may want to structure
your application around that. Or, at least the part that performs this
batch insertion. Even a relational database management system will most
likely have issues with performing that type of duty directly (without the
Django layer) unless it's optimized and tuned correctly, sitting on
extremely fast IO hardware, etc...

Judging from your times with SQLite, I would guess that part of your
problem is the IO performance (Hard Drive), since SQLite stores its data
directly into a file.

Not sure if this answers your question but hopefully it might lead you in
the right direction :) Good luck!

RE: [] Resubmit on error middleware

you could return a HttpResponseRedirect and handle your error on a different

Re: Registering only folks with .org email

[Kurtis Mullins]

Hey Steve,

There's a number of ways you could go about tackling this task. I,
typically, would read the original's application code and first determine
how it worked. In some cases, I would write my code to subclass (or re-use)
theirs and just make the modifications required. Other times, depending on
the complexity of the particular function/feature, I would simply roll my
own out based on what I've learned.

Another great way to go about this, since your effort could potentially be
something useful to others, is to see if the "registration plugin" is
available on github with the proper licensing and then "fork" it. You could
make all of your changes there on github and use "pip" to install your copy
(the fork you made) instead of the original author's. This would be great
because you get to share with others, have a manageable way of monitoring
your changes, and may even get some help from others.

Anyways, those are just some ideas... I'm sure others will have more!

Good luck!
- Kurtis

Re: .filter(Q(childobj__attr1="something", childobj__attr2__gte=100)) and .filter(~Q(childobj__attr1="something", childobj__attr2__gte=100)) Don't Produce Opposite Results

[Kurtis Mullins]

Let's write this in logical notation

models.ParentObj.objects.filter(Q(childobj__attr1="something",
> childobj__attr2__gte=100)).count()


A AND B

This query should give you all objects where both attr1="something" is true
AND attr2_gte=100 is true. Does this sound right from the data you have at
hand?


> models.ParentTable.objects.filter(~Q(childtable__attr1="something",
> childtable__attr2__gte=100)).count()
>

~ ( A AND B ) = ~A OR ~B

This query should (at least according to logic, I'm not sure according to
Django's ORM) give you all objects where EITHER attr1="something" is false
OR attr2 >= 100 is false.

Again, does your data set show this is true?

I believe ... just from reading what you've posted, that you actually want
the Complement of the set of objects. Maybe something along these lines
would help you?

showing a second level of indirection in an admin change_form page

[Tomas Neme]

Anyone knows of any trick that will let me show a second-level
indirection inline

via a one2one, so ModelA <-FK- ModelB <-one2one- ModelC, and show A,
B-C-B-C-B-C kind of thing?

Maybe I can override the get_formsets in the admin?

Really? What is the use case requiring a version 2.0.0? Seems that the 
previous 1.x version works as advertised.


And typically folks don't jump on a x.0.0 of anything, expecting to see 
it settle down after release with some minor fixes and additional 
releases. That may be the case with the GeoDjango folks though I don't 
know for sure.

PostGIS 2.0 has a lot of stuff in it, including things like KNN indexes; those 
alone are worth upgrading for.

Well, 2.0 has been out for four months so far, so it's not exactly a brand-new 
release.

Re: [] Resubmit on error middleware

[Paul Pietkiewicz]

I've written my own middleware class with a process_exception method to 
capture the exception, and remedy the underlining condition which caused 
the exception. The point is to transparently resubmit the request without 
actually returning anything to the client. Basically to retry the entire 
request and return the result to the user without notifying the user of the 
retry. Is that possible?

Paul

favourite reusable apps

[jondykeman]

Hi Everyone, 

I have found when getting into Django that at least once a month I find 
a reusable app that replaces the need for what I had spent the last ~2 
weeks figuring out how to write myself. 

As such, I thought it might be nice to start a thread of everyone's 
favourite / most useful apps that they find themselves re-using over and 
over again.

If I were to start it off I would go with django-extensions 
(https://github.com/django-extensions/django-extensions/) for some very 
useful additional commands via ./manage.py that come in handy with almost 
every project.

It's a community site specifically aimed at cataloging Django apps
according to what they do, and how popular they are.

Form Wizard usable with branching?

[mtnhiker]

I think I must be missing something. To me a wizard should provide 
questions and branch according to the answers (otherwise why not just put 
it all in one form?).  I've searched the docs and web and source, but I 
don't find anything that lets me branch.  I thought the "condition_dict" of 
the wizard view would do the trick.  Seems not.

Using the condition_dict can say when a step should be skipped.  But this 
isn't the same as jumping to a specific step.

What I really want is to (somewhere!) check the values of a form right 
after the user hit "submit". Based on those values, jump to the next 
appropriate form.

What is broken in my thinking about this?  Are people actually writing 
wizards with 1.4 that use the form wizard and do branching?

Re: Form Wizard usable with branching?

[mtnhiker]

Answering my own question...

I debugged my brain a bit and got something working with branching.  Here's 
my interpretation of my brain bug.

First a "step" is not something attached to a particular form.  Its the 
index in a sequence.  The same form might be step 2 with one branching 
structure but step 3 for another.

Second, the "condition_dict" keyword to wizard.as_view() should be thought 
only as "use or don't use" a form. For me, this mean I had to stop thinking 
of how to make the wizard go from one node to another in a flow chart.  Its 
as if all nodes in a flow chart are possible and the condition_dict is used 
to look up-stream in the flow-chart to decide if a particular node (form) 
should be used.

I still would like to be able to design a wizard as a flow chart wtih 
branches that switch based upon field values. I'd like to do this very 
directly.  Perhaps I will write a django contrib that effectively tales 
input as a directed-graph that represents the flow chart, and generates the 
right condition_dict to make it happen.  (but first I have an app to build)

Re: PostGIS 2.0.0 problems

[Will Tuladhar-Douglas]

Folks,

I just checked and I'm running Postgres 9.1 and Postgis 2.0SVN with GeoDjango 
(on Mac OSX 10.7.4) . I'm not doing anything very exciting with GeoDjango so 
far, so perhaps there are problems I haven't encountered, but it does run, and 
it is possible to encode locations using the GeoDjango ORM features. I didn't 
do anything special for Django (1.4.1) or GeoDjango, but setting up PostGis 
does need to be done right, and the special version of psycopgsl is required - 
all of that is well documented, though.
