dumpdata and loaddata as simple DB migration tool?

[Kegan]

Hi,

About Django database migration. I know there's a couple of tools
available (South, evolution, dmigration, etc), but I am pondering an
alternative here. Hope good discussion entails.

This is what I am doing manually now for my database migration needs.

1. Use Django's management command "dumpdata" to get the JSON
representative of an app. Save the JSON into a file (oldmodel.json).
2. Git pull the latest code. And do a reset to the app. So the
database will have the new model schema now.
3. Use the python shell to migrate the JSON file to match the new
model representation. Save the new JSON into a file (newmodel.json).
4. Use management command "loaddata" to populate the new model with
the newmodel.json.

This has work well so far for my use with PostgreSQL, albeit very
manual. It's all Python code.

So I guess what I want to ask Django experts/developers here is that:

1. Is there any reason this shouldn't be done?
2. Any technical challenge that prevent this method from being
realized into a more automate tool? (I read somewhere that dumpdata
doesn't always work?)
3. What do you think about having migration code be more part of the
deployment tool, rather than couple into the source code ?

Thanks.

Django 1.1 to be in future Google App Engine release

[Kegan]

Just for everyone information, I believe Guido just said that Django
1.1 will be in future Google App Engine release once it (Django 1.1)
is out of beta.

Looking forward to this Django 1.1 final!

How would I do this ...

[tsop]

Hello! I have hit a small road block in designing a fairly simple CMS
application:

My url pattern is:

url(r'^(?P[A-Za-z-_//]+)/$', page_handler, name='page_handler')

I'm capturing whatever URL handing it off to a page handler view
function that matches up a Page by slug and returns it .. this works
great for textual content.

View:
def page_handler(request, url=None):

#Default to page root when no url
if url == None:
page = get_object_or_404(Page, id=1)
else:
page = get_object_or_404(Page, slug__exact=url)

if not page.template:
template = 'cms/default.html'
else:
template = page.template

return render_to_response(template, {
'page': page,
'request': request,
})

I am trying to figure out if there is a way to pass additional context
to a template from the view, say I have made a contact page but this
page needs to access a form, currently I don't know how I would  be
able to do that, that is, to pass the form context to whatever
template the Page specifies. Normally I'd just map a URL to a
"contact" view function that handles the form and passes it off to a
template. I am trying to be efficient about this without "hard-coding"
that in ... if that makes sense.

Any help is appreciated!
Regards, Titus

What's the output from each of these commands: (all at the command prompt, one 
at a time)
  ls -dl /home/morgan/www
  ls -dl /home/morgan/www/mysite
  whoami
  touch /home/morgan/www/TESTFILE

After the last one, does the file /home/morgan/www/TESTFILE exist?

Django Registration templates not talking to my other pages. Sometimes.

[Matt]

This is a weird one. It's so weird, I'm positive I'm making a very
dumb mistake somewhere. This is my MO.

Anyway, I am trying to use django-registration to do some very basic
login, logout stuff. I'm using RequestContext to make usernames
available to all of my templates, like so:

//views.py
from django.template import RequestContext
def detail(request):
...
context = { 'employees': employees, 'entityinfo': entityinfo}
return render_to_response('results/resultstable.html',
context_instance=RequestContext(request, context))
//

I'm doing some variation of the same in all of my views.

The problem is my {{ user }} (which I'm using in base.html) isn't
showing up in the majority of my pages. It shows up on all of the
django-registration pages that start with "/accounts/." It also shows
up on my index page, which is the redirect from the login page.

Here's the curveball: When I log in to the admin site, and then go to
my project, everything works smashingly. I can go to all of my pages,
and it says, "Hi, Matt!"

What is going on here? I assume I either am using registration
incorrectly, or am using RequestContext incorrectly. Or both.

Managers to aggregate child object values?

[Streamweaver]

I'm pretty new to Django still and I know much is still escaping me.
In particular I'm having trouble still with how to query subsets of
related objects.

In this case I have two Models.

class Project(models.Model):
title = models.CharField(max_length=141)
...

class Release(models.Model):
project_fk = models.ForeignKey(Project)
point_estimate = models.IntegerField(choices=ESTIMATE_CHOICES,
null=True, blank=True)
velocity_points = models.IntegerField(choices=VELOCITY_CHOICES,
null=True, blank=True)
...

What I was looking to do is create a way sum the total number of
velocity points in releases related to a Project.  I also wanted to
sum the total number of point_estimate points related to a Project.

>From what I see a Custom Manager would seem necessary but I'm getting
confused on related objects and aggregating items.  This is for Django
v 1.0 and would not include v1.1 aggregation features.

Thanks in advance for any insight.

You've apparently got  'django.contrib.sites' listed in your INSTALLED_APPS
and you have set SITE_ID in your settings file to a value that has no match
in your Sites table.  As mentioned here:

http://docs.djangoproject.com/en/dev/ref/contrib/sites/#how-django-uses-the-sites-framework

the auth app's login view, which the url you are testing is mapped to,
attempts get the current site name (if the sites app is installed) and pass
it as the variable site_name to the template.  It's not finding a match when
it attempt to retrieve the currents (i.e. SITE_ID) site.

This isn't really the right way to extend the django user model:
http://www.b-list.org/weblog/2006/jun/06/django-tips-extending-user-model/.
 However, if you insist on doing it this way you would need to alter
the
admin.py file in the same directory.

You must follow the tutorial, and the django book, first.

It is really easy. Do it yourself, not just reading or cut & paste.

Familiarize yourself with Django's documentation, and look for
available Django books.
Look for Django code, and try to see how it works.

Good luck!!

Django doesn't.  It's a server side web framework.  It neither a) knows
about the client side, nor b) handles printing on the server side because
that's a task for some sort of printer/scanner library.

Re: django-reversion with recent svn django

[Tim Sawyer]

Fixed it.

I was assigning a string to a date field.  Django is ok with this, django-
reversion isn't.

Changed:

lDate = '%s-%s-%s' % (lYear, lMonth, lDay)
lContestEvent.date_of_event = lDate

to:

lContestEvent.date_of_event = date(int(lYear), int(lMonth), int(lDay))

and all appears fine.

django-reversion with recent svn django

[Tim Sawyer]

Hi,

I'm using django svn 10784, and I've just added django-reversion, latest svn 
version from trunk (198).  I'm using the middleware option for django-
reversion.

It's not working, and I'm getting the following error.  I've tried with the 
same django version and the tagged 1.1.1 release of django-reversion, but I 
get the same problem.

The error occurs on a save and is:


Traceback (most recent call last):

  File "/home/mybandsite/django-trunk/django/core/servers/basehttp.py", line 
278, in run
self.result = application(self.environ, self.start_response)

  File "/home/mybandsite/django-trunk/django/core/servers/basehttp.py", line 
636, in __call__
return self.application(environ, start_response)

  File "/home/mybandsite/django-trunk/django/core/handlers/wsgi.py", line 245, 
in __call__
response = middleware_method(request, response)

  File "/home/mybandsite/src/reversion/middleware.py", line 23, in 
process_response

  File "/home/mybandsite/src/reversion/revisions.py", line 263, in end

fields=registration_info.fields)

line 87, in serialize

  File "/home/mybandsite/django-trunk/django/core/serializers/base.py", line

self.xml.characters(field.value_to_string(obj))

  File "/home/mybandsite/django-trunk/django/db/models/fields/__init__.py", 
line 518, in value_to_string
data = datetime_safe.new_date(val).strftime("%Y-%m-%d")

  File "/home/mybandsite/django-trunk/django/utils/datetime_safe.py", line 30, 
in new_date
return date(d.year, d.month, d.day)

AttributeError: 'unicode' object has no attribute 'year'

I think this might be something to do with my MIDDLEWARE_CLASSES which is set 
to:

MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.transaction.TransactionMiddleware',
'reversion.middleware.RevisionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.doc.XViewMiddleware',
)

which doesn't match the recommendation from the django-reversion site.  I had 
to put the AuthenticationMiddleware first so that request.user was available 
for the RevisionMiddleware to use, and that dragged the SessionMiddleware in 
too.

Any clues anyone?

Thanks,

Tim.

Couldn't you do this with the post-save signal?
http://docs.djangoproject.com/en/dev/ref/models/instances/#what-happens-when-you-save

Create a signal that listens for the save of a admin and have it place
an admin into your group if they aren't already.

That way you could could add your new admin user to your special group.

You could write up something similar to get_language() in
utils.translation or use threadlocals. I don't know if this is
actually a good idea.

This is not the /www directory, but the /home/morgan/www/ directory.
You do not need ownership (although it is customary of directories under
your home directory), but write permission.

Execute
sudo chown morgan ~/www
sudo chmod 755 ~/www

If there are any files in ~/www, such as an existing 'mysite' directory,
delete them.

Automatically creating auth.models.group for an application

[eric.frederich]

In an application I'm writing I have a model that stores admins by
location in a model called LocationAdmin.  So in this model I have a
foreign key to User and a foreign key to a Location object.

I would like to override the save() method so that when an Admin is
created they are assigned to a special group (auth group).  This group
would be called something like "Location Admins" and have various
permissions.

I have having a hard time finding a way let alone the correct way to
do this.

I feel that the group should be created when running syncdb but by
using a fixture I'd have to hard code the permissions keys that the
group needs.

Its almost like I need a fixture that runs some python script that
runs Permission.objects.get to go after the wanted permissions.

Is there a mechanism to do something like?

overriding model field defaults in inherited model class with static methods

[herr.klein...@googlemail.com]

Hi.

I'm trying to override the defaults of an text field in an subclass. I
thought i could accomplish that by the following code, but
models.TextField(default = default('flags')... wouldn't find default
(). I cant reference it by self.__class__.default() as the is no self
at the field initialization. Im kind of stuck ...

Thank you for your help!

class Compiler(Model):

class Meta(Checker.Meta):
abstract = True

# default values for the model fields
defaults = {
'flags' : "-Wall -static",
'output_flags'  : "-o %s",
'libs'  : "",
'file_pattern'  : r"^[a-zA-Z0-9_]*$"# 
Regular expression
describing all source files to be passed to the compiler.
}

def default(key):
""" By making the model field defaults a callable instead of an
value it will be called every time a new object is created wich will
allow for altered defaults in subclasses. """
return defaults[key]

_flags  = models.TextField(default = default('flags'),

Possible memory leak moving to Django 1.1 from 1.0.2 in mixed use test.

[proteus...@gmail.com]

We've got an application that is running behind apache, mod_wsgi and
front ending a postgres 8.3 db. We needed to upgrade our Satchmo to
the latest version which requires Django 1.1.  After the upgrade the
system starts eventually running out of memory until it thrashes and
locks up the machine under a fairly light load, just a few reqs per
second. I can understand the system using more memory but it doesn't
seem to release it when the load stops.

This graph: http://www.flickr.com/photos/proteusguy/3589788760 shows
the results of both systems which, besides the Django & Satchmo
versions are identical. You can see that when the test completes on
the old system the process returns a great amount of memory but the
new one never releases the memory. In production this will eventually
grow to consume all RAM. This particular test is of a set of 7
different requests simulating what a typical user might do.

This graph: http://www.flickr.com/photos/proteusguy/3589788752 shows a
similar test except it only contains a single request out of the seven
from the prior test. We were hoping to identify that something in one
of our requests was the cause of the problem but similar exclusive
test runs with all 7 requests from the combined test from above show
similar results - fairly stable memory usage.

This leads me to believe that the issue is systemic to django, most
likely in the db handling as most of the requests don't touch the
Satchmo system. If this was a C++ app I'd be able to figure this out
pretty quick but I'm not sure how to attack the problem in a dynamic
language environment like python. So this leaves me with two
questions:

1. Is anyone else seeing this kind of memory extra memory usage and an
inability to return memory once requests end?
2. What suggestions does anyone have about how I can determine what
aspect of the system is using this extra memory and holding onto it?

thanx very much,

Do you use a skeleton for new django sites?

[Aaron Maxwell]

Hi all,

When creating a new django based website, my first step used to be to 
invoke "python manage.py startproject".  The files created would be the first 
or second commit into version control for that project.

I found, however, that I would always make a similar set of changes right 
after: certain configurations and changes to settings, creating an apps 
directory (module), 404 and 500 templates, etc. 

So what I do now is I have a separate project, which I call django-skel, that 
is just a new project file layout with the changes I already want to make for 
every project.  For each new project, I just export from that, copy the files 
into the new project space, and commit.

Over time, I'll discover something new I'll want to add to all my django 
sites.  So I just make that change to django-skel and forget about it.

Does anyone else follow this technique?  Or do you have some different 
approach that solves this problem for you?

Thanks,
Aaron

You might need to provide some actual model definitions.

Generally, you can use the double-underscore format in order_by, so
you can do this:
ModelA.objects.filter(field=x).order_by('modelb__field')

Is that what you want?

Because enumerate() is an iterator. So it is consumed the first time
it is run.

You could call list() on it to flatten it:
SALES_TEAM_CHOICES = list(enumerate(('CLS','CCS','TPS')))

I've never heard of anyone doing this, which is presumably why it's

Re: inline model's choices field empty in admin

[ryan]

This additional model, which uses the same choices is emptying the
choices dropdown of both User with inline UserProfile and UserProfile
itself.  Add it prior to UserProfile in models.py of your test app:

class Person(models.Model):
sales_team = models.IntegerField(choices=SALES_TEAM_CHOICES)
user_class = models.IntegerField(choices=USER_CLASS_CHOICES)
last_name = models.CharField(max_length=40)
first_name = models.CharField(max_length=30)

This behavior is not mentioned as a caveat in
http://docs.djangoproject.com/en/dev/ref/models/fields/#choices

AuthenticationForm adds a 'request' (keyword or first positional) parameter
to the standard Form arguments:

http://code.djangoproject.com/browser/django/tags/releases/1.0/django/contrib/auth/forms.py#L54

So if you are instantiating an AuthenticationForm without passing in
'request' you need to specify what's normally simply the first positional
Form argument by keyword (which is 'data'), because if you pass it as simply
first positional it will be assigned to 'request'.

Not sure if that explains what does not make sense to you?

(Both the details of AuthenticationForm and the fact that the first
positional argument to the base Form class has the keyword 'data' could
probably use a bit more explicit documentation, unless I'm missing where
these things are currently covered...I couldn't find them in a brief
search.)

I cannot recreate this with either Django 1.0.2 or current trunk.  When I
cut and paste the models/admin defs you show into a test app and then edit a
user in admin, the two profile dropdowns are populated with an empty choice
(all dashes) plus the choices you have specified.  There must be something
beyond what you have shown here that is coming into play.

Re: Markdown Encoding Problem

[bfrederi]

Yes. I completely missed that ticket, but I had switched to importing
markdown normally instead of through Django, and it solved my
problems.

But I noticed on Ubuntu that the repository version of python-markdown
is still 1.6. So I will switch to a newer version of Markdown. Thank
you both for your help.

inline model's choices field empty in admin

[ryan]

When I edit a User in the admin, the sales_team and user_class
dropdowns are empty.

If anyone can point out my error or point me to the django core code
that ignores the choices, I would greatly appreciate it.

#models.py
SALES_TEAM_CHOICES = enumerate(('CLS','CCS','TPS'))
USER_CLASS_CHOICES = enumerate(('DOM','DSK','DFA','DTM'))

class UserProfile(models.Model):
user = models.ForeignKey(User, unique=True)
sales_team = models.IntegerField(choices=SALES_TEAM_CHOICES)
user_class = models.IntegerField(choices=USER_CLASS_CHOICES)

#admin.py
class UserProfileInline(admin.StackedInline):
model = UserProfile
max_num = 1

class CustomUserAdmin(UserAdmin):
inlines = [UserProfileInline,]

admin.site.unregister(User)
admin.site.register(User, CustomUserAdmin)

Search in one table, order by a field in another table

[Larry]

Hi,

Here is what I want to do:

I have one table A with two columns: user_id, msg_id (ManyTOMany)
and other table B with two column: msg_id, msg_time

Now I want to search for msg_id's of a certain user_id in table A, and
display the msgs
ordered by the msg_time.

Could anyone tell me how to do this?

Many many thanks!

Re: Having trouble authenticating/validating

[gsnyder2007]

Had the same issue and the info below allowed me to resolve the issue,
i.e. is_valid() is now returning True on a valid username/password
combination. Seemed to me that the key was setting the test cookie and
assigning the POST data into the 'data' variable. The former makes
sense to me. The latter does not. I wonder if anyone out there can
explain why.

Utilizing Admin Views but with custom subset

[malexs]

I have successfully created a little app and i would like to leverage
the already existing admin interface rather than reinvent the wheel
and create my own table listings I have managed to do this fine
for simple models but in this case i have a custom queryset that i
would like to use.

Essentially I have a Report that is contains multiple ReportItems. A
ReportItem is a subset/filter of the Log model. I want to display
multiple subsets/filters of the log model all joined together in a
table in the admin interface. I have managed to do this in the
views.py but it looks basic and is missing all the funky kewl sorting
and things that is present in the admin interface.

So is there a way for me to feed my queryset querySets into the admin
interface?

proxy table filtering

[Gord Allott]

Hi,

I have been a Django user for a long time now but only recently ran
into
a position where have needed to use Generic relationships, I need to
be
able to do something similar to filtering on a GenericForeignKey.
Essentially I have a media management app that looks something similar
to the following:

class MediaProxy(models.Model):
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()

content_object = generic.GenericForeignKey()

class Media(models.Model):
title = models.CharField(max_length=160)
uploader = models.ForeignKey('auth.User')
proxy = generic.GenericRelation(MediaProxy)

class Meta:
abstract = True

class Image(Media):
content = models.ImageField(upload_to='media/')


The idea being that no matter how many different types of media I have
(images, video, audio, etc..), I can still have them all grouped
together via the MediaProxy model. Although there's a problem in that
you can't filter on the GenericForeignKey attribute because it doesn't
exist in the table.

So I am wondering if anyone knows any way of filtering over multiple
models that inherit from one parent model (and thus are similar)
without
specifically having to run a filter on each model individually as that
would violate DRY and make it a large pain to add new media types.

Any help would be hugely appreciated, thank you. gord.

Karen nailed it. If your are using anything prior to Markdown 1.7
upgrade immediately (the 1.6 series was horribly buggy). Actually,
Markdown is currently at version 2.0.1 [1]. With 2.0 we've made a
number of improvements in a number of ways. However, one thing we are
dedicated to keeping the same is that since 1.7, Markdown will only
ever accept unicode text as input - nothing else. That has been a
tremendous help in eliminating these kinds of problems.

Tastiest show-off Django template filters

[Daniele Procida]

I'm doing a demo of some of our Django work soon. Partly, it'll be a
showcase for Django. One thing I'd like to do is demonstrate Django's
template filters, to show how powerful it is and how it can make a a
contribution to the quality of web output.

So far I have:

* typogrify
* humanize

Are there any other must-have candidates for this list?

Thanks,

Daniele

Re: Using Request Info in Generic Views

[Sieker Adi Jörg]

Hi,

you can use this: 
http://docs.djangoproject.com/en/dev/topics/auth/#authentication-data-in-templates
 
  to add the user to the template context.

Then you cold write template tags to actually get the data you need  
using the user template variable.

Hi your best bet is to do the following - I used this for something
else but you'll get the idea:

from django.template import resolve_variable
from django import template
from django.template import Library, Node

register = template.Library()

class AlertNode(Node):
def __init__(self, request):
self.request = request

def render(self, context):
request = resolve_variable(self.request, context)

# Do something with the session
var = request.session.get('js_alert', None)
if var:
del request.session['js_alert']
return str('alert("%s");' % var)
else:
return ''

@register.tag(name="get_js_alert")
def get_js_alert(parser, token):
try:
tag_name, request = token.split_contents()
except ValueError:
raise template.TemplateSyntaxError, "%r tag requires exactly
one argument" % token.contents[0]

return AlertNode(request)

# Usage: {% load js_tag %}{% get_js_alert request %}

You now have acces to POST, GET and SESSION ect in your templatetag.

Using Request Info in Generic Views

[Keyton Weissinger]

I know I'm in the minority, but I'm still having some trouble grokking
the details of generic views. I keep thinking I should be using them
but keep running into the same issue.

Here's my problem: I am building a mgmt site for schools in which
schools sign up for a monthly service fee. Most of my models have a
"school" foreign key which is also part of the user's profile.

So to see, for example, a list of teachers, I do something kind of
like this (assumes login has already occurred):

def myview(request):
   current_person = request.user.get_profile()
   current_school = current_person.school
   teacher_list = Teacher.objects.filter(school=current_school)
   etc

Almost everything I have has this school property.

My question is this: How do I leverage generic views in this capacity?
Is there a way to use the request information (specifically
request.user.get_profile().school in my case) in my urls.py when
generating my querysets?

Thank you!

Keyton

In your user account, run:

  LANG=en
  export LANG

and then run Django's own development server.

Does the application when run under Django's development server then
break also?

If it does, that should indicate reasonably well what the problem
likely is.

Re: ModelForm problems, Programming Error 1146

[Robocop]

Well i only say the e.save() line causes social mayhem as when doing a
line by line debug of that section, that's the command that causes all
the trouble.  I suspected there's a problem with my dispatch.cgi
script, as if i were to manually add the table i get the same behavior
(though adding the redirect middleware solved some issues, i'd only
had the fallback middleware showing up).  The url it directs to hits
the same function just that it triggers a if request.POST statement,
and with all my sloppy fixes in place my error_log looks like:
http://dpaste.com/50434/

Now my only concern is any significant trunk differences between my
installation and the model installation a peer has shown me (which i
don't have open access to).  With what i've seen i believe it to be
either a version discrepancy issue (as i don't know much about the
django redirect apps) or something wrong with my dispatch.cgi.  I will
double check my URLS to be sure, but do either of my suspected causes
seem probable for this type of issue?  And again, thanks for the
input, i think this has been more than once from you;)

Re: Django with ajax

[Jorge Bastida]

Hello Marc,

You can render a template into an string.

from django.template.loader import render_to_string
my_template = render_to_string('template.html',{'some':'data'})

If you want to send the list of objects to the browser you can use
serialization into json:
http://docs.djangoproject.com/en/dev/topics/serialization/#id2

In other hand, i'm currently developing Dajax (
http://code.google.com/p/dajaxproject/) it will help you using ajax in
django. For example, for sending serialized objects to the browser and use
it as you want in JS.

Thanks

Django with ajax

[Aldo]

Hey,

I have some ajax running on my pages.

I want to have it pass back some objects. However, I am unsure if I
can pass a list of objects back. So far I have only ever passed back
raw xml or text. Can objects be passed and then iterated via the html
template?

Thanks

Re: extending django-registration ( MixIn ModelForm and Form)

[Marco Bazzani]

yes the problem using this method is that DRY principle is broken,
because you redefine the fields that are already defined
I was thinking of MixIn the 2 Forms to keep the whole thing reusable
but nevermind, if this is the only way, I'll do it like this.
thanks

For completeness sake: RequestContext *and*  
django.core.context_processors.auth in TEMPLATE_CONTEXT_PROCESSORS  
(it's there by default unless one changes configuration).

Re: filtering the join table in a many-to-many relationship

[Ben Adida]

Sam,

Thanks for the rapid response. I think I see what you mean, but I'm
not sure it solves my problem.

Looking at the example you sent, here's how my problem would look in
that context:

- Friendship has an extra column called "degree_of_friendship", which
can be "meh", "good", or "great"
- I want to find all of Bob's "great" friends.

I can get Bob's great friendSHIPS by doing this:

Friendship.objects.filter(first = bob, degree_of_friendship = "great")

or I could get all of Bob's friends:

bob.friends.all()

but how do I get the Friend objects that are "great", but not others?

In other words, how do I impose a constraint on the Friendship join-
table when I do bob.friends?

-Ben
