Re: [django-users] Error when registering a new user - Django 1.5

[Russell Keith-Magee]

Variations on this problem report have been made a couple of times

UserCreateForm is a ModelForm. That means the line in your Meta clause for
model=get_user_model() is invoked at the time the module is loaded.
However, there's no guarantee at the time that module is loaded that the
user model has been defined yet -- so you can end up with errors.

There are two options here.

Option 1: We try to define a truly dynamic UserCreateForm that can adapt to
the changing requirements of a User model (and remember, this means
adapting to the REQUIRED_FIELDS as well). This code would be complex and
potentially fragile, since it needs to work with *any* User model, with
*any* collection of required fields.

Option 2: We provide a UserCreateForm that works with the default User
model, and with any AbstractUser descendent that isn't too significantly
modified, and we leave the UserCreateForm for any other User model an an
activity for the developer.

We've chosen Option 2, and documented as such:

https://docs.djangoproject.com/en/1.5/topics/auth/customizing/#custom-users-and-the-built-in-auth-forms

Re: Python inside Django

[Shawn Milochik]

You can completely eliminate Django from your thinking about the
problem. This is a pure Python question.

A Python file being within a Django project changes nothing about how
Python imports code. Either you're importing something on your Python
path or you're doing a relative import. If your import is failing,
then just import it using its full location on the PYTHONPATH.

The only other consideration is if your code isn't anywhere on your
PYTHONPATH, in which case all you need to do is add it. You can add it
to sys.path in your code, but my preference is to use virtualenv for
every project and put my project path in my PYTHONPATH that way.

You can easily do it from the command line manually first just to make
sure it works. Something like:

export PYTHONPATH=$PYTHONPATH:/path/to/my/code

Then run your code and make sure it works. When you have it working,
do something more permanent. I recommend the virtualenv method.

Re: Create Django web apps with drag and drop interface builder

Thanks for the checking the project out and for the advice! I am hoping to 
add more and more documentation over the next few weeks, in addition to 
possibly some screen casts. I will look into how to best support bootstrap 
(and foundation) within the framework, as your right a lot of people are 
using these now.

Thanks again,

Create Django web apps with drag and drop interface builder

[timothy crosley]

Hi, 

For the last few years I have been working on a WebApplication framework 
designed to let you build complex web apps using a drag and drop interface 
builder
and pure python code. I have just now released it to the public and would 
really like feedback and opinions. You can see it here:

www.webbot.ws


These applications can then run on top of Django or AppEngine.
I hope other Django users find it useful!

Python inside Django

[Felix Wagner]

Hello,

currently I am writing an application that will run a daemon. However I am 
stuck:

What I have so far:

created a project called "ihe", with an app called "devices". Inside 
devices there is "admin.py", "forms.py", "__init__.py", "models.py", 
"urls.py", "views.py".
There are also several directories: "configuration" contains "config.py", 
"__init__.py" and "logging.conf", the "daemons" directory contains the 
daemons that I want
to execute. A standard "managment" directory containing the management 
calls. And lastly a "utilities" direcotry containing "hwcontrol.py" and 
"utils.py".

My issue is that if I want to for instance import hwutils which is pure 
python inside a daemon or a "from devices.models import *" inside a daemon 
or any other file it always complains about an import error:

"Traceback (most recent call last):
  File "database.py", line 14, in 
from devices.models import *
ImportError: No module named devices.models"

"Traceback (most recent call last):
  File "database.py", line 14, in 
from devices.utilities import hwcontrol
"ImportError: No module named devices.utilities"


If I understand correctly this is because of the python path. For instance 
the pythonpath for a daemon:

['/~/software/ihe/devices/daemons', '/usr/lib/portage/pym', 
'/usr/lib64/python27.zip', '/usr/lib64/python2.7', 
'/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', 
'/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', 
'/usr/lib64/python2.7/site-packages', 
'/usr/lib64/python2.7/site-packages/Orange/orng', 
'/usr/lib64/python2.7/site-packages/PIL', 
'/usr/lib64/python2.7/site-packages/gst-0.10', 
'/usr/lib64/python2.7/site-packages/gtk-2.0', 
'/usr/lib64/python2.7/site-packages/wx-2.8-gtk2-unicode', 
'/usr/lib64/portage/pym']

However I thought that if I put the files inside the django project that 
the imports would then work. What do I have to do to get it working?

Thank you for any help.

Re: DB Weirdness

[Tim Cook]

Just to complete this issue.
I knew it was a silly mistake.
I had reconfigured my settings.py according to  recommendations from TSD.
BUT! I did not delete the original settings.py file.  So all the
changes I Was making had no effect. Django was using my new
settings/dev.py

Applying admin site foreign key filters when adding new object

[Branko Majic]

Hello,

I'm interested what's the proper/best way to restrict foreign keys when
adding a new object through the admin interface.

For example, let's say I have models like this:

class Project(models.Model):
name = models.CharField(max_length = 100)

class Entity(models.Model):
name = models.CharField(max_length = 100)

class Connection(models.Model):
name = models.CharField(max_length = 100)
first = models.ForeignKey(Entity, related_name = "first_set")
second = models.ForeignKey(Entity, related_name = "second_set")

And let's say I have an admin class like this:

class ConnectionAdmin(admin.ModelAdmin):
list_display = ('name', 'first', 'second')
list_filter = ['first__entity__project']

What I need to be able to do is when I select a particular project in
the admin interface, and proceed to then add a new object, get the
filter applied to my foreign key fields.

Right now, what I'm doing is overriding the formfield_for_foreignkey in
the above ConnectionAdmin class to get this behaviour, but the tricky
part was actually getting this project filter information available to
my overridden method. The way I did it was by overriding the
chante_list.html admin template. Inside of it I've done this:

{% extends "admin/change_list.html" %}
{% load i18n admin_static admin_list %}
{% load url from future %}
{% load admin_urls %}

{% block object-tools-items %}

  {# Add the GET parameters from the admin's filter to 'Add entity' 
button #}
  {# so we can perform some filtering on first/second. #}
  
{% blocktrans with cl.opts.verbose_name as name %}Add {{ name 
}}{% endblocktrans %}
  

{% endblock %}

I.e. I'm overriding the link for adding the new object to include get
parameters that are the same as the ones used for filtering in list
view.

So, is this the right way (or did I fail to find the information in the
documentation on this)?

Best regards

P.S.
The actual application code I'm working on can be found at (the above
example is a bit simplified to what I have):

Re: POSTing JSON to Tastypie from Android

[Pratik Mandrekar]

Thanks for the pdb tip Bill!

I tried pdb at the point where the request enters Tastypie (based on 
http://stackoverflow.com/questions/13006901/tastypie-obj-create-method-not-being-called).
 
What I see is that the request.POST and request.raw_post_data are both 
empty. I posted from Android client to a posttestserver and I can see that 
all the headers I set and the request body are set.

However it does say that there are no POST parameters. Here is the logged 
request - http://posttestserver.com/data/2013/03/23/06.42.591241431084. Any 
idea what that means? Note that I had to remove the authorization header to 
post to this server.

Also I'm not sure now where else to start the trace from. Is there another 
place I can pdb trace my HTTP request when it enters the app? Is it 
possible some data gets stripped off the original request somewhere?

Thanks.

Pratik

Re: Im having trouble accessing irc.freenode.net

[Bill Freeman]

If you are using FireFox, the Chatzilla add-on is easy to get, probably by
using the tools menu, choosing "Add-ons" and entering "chatzilla" in the
search box on that page.  It's not as fancy as some of the IM tools, but
you can have it anywhere that FireFox runs, and for IRC, it's pretty
trouble free.

Re: POSTing JSON to Tastypie from Android

[Bill Freeman]

Still, if you have a break point where the request comes in to the view,
you can inspect the POST data to see how it differs from what you expect.
That might inform you as to what you might do differently in your
JavaScript, whether you need some additional or different encoding or
quoting of the data, whether you need to be more explicit about the
content-type header (you may have to look at the WSGI request object
itself), etc.  Or you may discover that you need to breakpoint at the WSGI
application script level to see what you need to see.

Since nobody has jumped in with "I recognize that problem", inspecting your
data is probably a good use of your time.  pdb is not hard to use, as long
as you are using runserver (and you can almost always arrange to explore a
problem under runserver) because there has to be a console for pdb to type
on, and on which you can type commands.  The first breakpoint is the only
django specific trick.  Put

import pdb; pdb.set_trace()

where you want to stop.  You can use the b command to set additional
breakpoints later, but that can be confusing due to threading.  pdb is
documented in the library reference for your python version at python.org.
Read up on the p, pp, u, d, c, n, s, r, !, and q, commands, probably in
that order, and you will find that you usually only use the first 5 of
them.  (There are more, for when you want to be a pdb expert.)  And
remember to start with a p or pp when you want to see the value of an
expression, lest your expression be interpreted as one of the other
commands.

Re: POSTing JSON to Tastypie from Android

[Pratik Mandrekar]

The issue is with setting data in the http post request. I have tried it 
with curl and the web client and it works. CSRF is not the issue, requests 
work fine without the csrftoken outside of the android client.

An alternate cry for help

[Christos Jonathan Hayward]

I wrote earlier asking if someone could correct my ignorance to go from
Pinax building blocks to a working site. Since then, I searched Safari, and
found five references to Pinax, at
http://my.safaribooksonline.com/search?q=Pinax . One is a tangent in a
Django book I wrote; three are Python books I didn't write; and one is an
iPhone JavaScript book that includes 'pinax' in a Greek-English lexicon's
URL.

I realized after posting the original post below that although I'm an avid
learner my ignorance of Pinax may be a bit of a challenge to straighten
out. So besides the possibility of educating me to really know how to put
Pinax sites together, could someone preassemble a complete social site that
just needs database setup, a syncdb, and a gunicorn invocation? It would be
nice to have the earlier Pinax Social Project reimplemented using the new
tools, as opposed to the pinax-social-project which is a set of building
blocks to complete a social project. It seems the general approach is to
turn over better and better building blocks to the user, but the
already-working sensible default has its merits, and I'd appreciate those
merits after a day of struggling with old Pinax, new Pinax, borrowed Pinax,
blue Pinax, not getting any responses with good learning resources, and
searching Safari and recognizing that O'Reilly's whole Safari does not
contain as much information about Pinax as the email you are reading, not
enough by half, and that kind of makes my ignorance a less changeable
condition. If I'm ignorant about Django but have the Django documentation
and the Django book, I can reduce my ignorance. Here I don't see how I can
reduce my ignorance, and my thoughts turn to an evaluation that working
Pinax is excellent, not-configured Pinax that you don't know how to improve
is worth very little, and Liferat is mediocre but works, in its own special
way.

*After a day or so of losing at trying to make pinax-social-network 1.0
have the merits of Pinax social-project 0.5 or .7, I'd like to ask how to
cut with the grain instead of against it.*

*The earlier version came as a fully functional site: you could override
and customize if you want, but it came "batteries included", as a room with
well-chosen pegs on the walls, pictures hanging on the hooks, and furniture
as needed. You could replace as much of the room's initial contents as you
wanted, but it came as a furnished room.*

*Pinax-social-network 1.0 is not a furnished room. It has pegs, and the
pegs are about as well-placed as you could ask for, but if you want
pictures on those pegs, it's on you to put pictures on the pegs. And there
is space you can put furniture in the room; the room is left empty so you
can put whatever furniture you want in. And the room comes with elegantly
placed lorem ipsum graffiti on the walls, to motivate you to paint or
wallpaper the walls to meet your taste. It comes "batteries removed."*

*So... what are the resources, and how does one go about, making a social
network here? Do I just take it as a bit of Django putty? I expect I'd do a
lot of reinventing the wheel if I just use Django knowledge. Is there a
tutorial that shows how to make a live site out of one of Pinax's projects?*

*I spent a bit of time reading about Liferat Liferay before remembering how
painful it was even when I knew it well. The problem here may just be that
I am ignorant about Pinax, and ignorance is a changeable condition.*

*So let's say I know something about Python, something about Django and
something about older, fully assembled versions of Pinax, but not how to
take a starter Pinax project and make a finished site out of it. I'm
ignorant on that point. How can I cure my ignorance? What resources are out
there so I can get what was so easily in reach in older versions of Pinax?*
