Tracking changes of a model
Hello, I am using Django admin to create/update some records. Now, I need to track changes. After somebody updates a record, I need to see what was changed and then create a text log like: changed `name`: oldvalue -> newvalue, changed `email`: o...@mail.xy -> n...@mail.xy Where is the right place, where I have access to unchanged model values and validated values from the submit form? The place before the model is updated by form values? Another approach would be to save all values into a dictionary after the model is loaded from database and in save() method compare old and new values, but I don't know how how to call a code after load.

table namespace hygiene: should I try to rename auth_* tables, or should I use a separate database?
django 1.2, python 2.6, mysql 5.1, etc. I am sharing a database with others on my project, and I would like to keep the table namespace neat and tidy. After poking around the archives for a while, I can't see any good way to specify names other than the default auth_group, auth_group_permissions, etc. for the auth module. I don't want my tables to get confused with someone else's. "auth" is unfortunately a very generic prefix. One can imagine lots of people making tables named auth_something. Is this renaming something that can be done in a reasonable way? If not, I could create a new database, and devote it to the django stuff. Is that a good solution? Are there significant disadvantages to using a separate mysql database just for the django stuff? Is there maintenance overhead for the dba? (I don't know.) Are there any disadvantages, say, to doing trans-database joins, or having trans- database key constraints, vs. within a single database? Does anyone see any other optimal ways to keep my table namespace clean? Thanks Alex -- You received this message because you are subscribed to the Google Groups "Django users" group.

Hi Michael, Databrowse hasn't seen a whole lot of attention since it was originally added, so there is almost certainly room for improvement. Moving to class-based views might be part of that process. If you want to adopt databrowse as a pet project and improve it, I certainly encourage you to do so. However, please don't just submit a patch that 'replaces function views with class-based views'. Change for the sake of change isn't something we generally encourage. Unless there's a compelling reason to migrate to class-based views, there's not a lot of reason to make changes to code that works. There was a recent discussion about porting the contrib.auth views to class-based views which received a simliar reception. I look forward to any proposals you may have for improving databrowse!

Re: Import csv file in admin
The ordinary user won't have to deal with the command line, you just
need to get the CSV file. A ModelForm to which an FileField is added
doesn't really have anything to do with that.
Instead, you should create a standard form with a single FileField to
upload the CSV file, save it temporarily or just keep it as a file
object and then process it as Jirka pointed out.

Felix

Yes, I noted that when I edit a url and sometimes the code, I have to kill the fastcgi process to see the result in the browser. I think that I could run the fastcgi as explained in the django documentation: ./manage.py runfcgi method=prefork socket=/home/user/mysite.sock pidfile=django.pid and map in vim file a kill command kill `cat $PIDFILE` Another solution is take a look at the uWSGI configuration Anyway is a nice topic ;-) -- K.

Re: Import csv file in admin
Felix
I try to follow the ideas, but i feel like taking the dirty way.
Here's my work:
Because i can't replace the modelform created by the admin for the
"Data" model with a standard form as the Django docs says, i created a
view to replace the "add" view generated by the admin and put a
standard form:
class DataAdmin(admin.ModelAdmin):
change_form_template = 'admin/data/data/change_form.html'
def get_urls(self):
urls = super(DataAdmin, self).get_urls()
my_urls = patterns('',
('^add/$',
self.admin_site.admin_view(self.add_view)),
)
return my_urls + urls
def add_view(self, request, extra_content=None):
FormInput = DataInput()
context = {'form': FormInput}
return super(DataAdmin, self).add_view(request,
extra_context=context)
And the form is:
import csv
from datetime import datetime
class DataInput(forms.Form):
file = forms.FileField()
place = forms.ModelChoiceField(queryset=Places.objects.all())
def save(self):
records = csv.reader(self.cleaned_data["file"])
for line in records:
input_data = Data()
input_data.place = self.cleaned_data["place"]
input_data.time = datetime.strptime(line[1], "%m/%d/%y %H:
%M:%S")
input_data.data_1 = line[2]
input_data.data_2 = line[3]
input_data.data_3 = line[4]
input_data.save()
In the template are the "multipart/data" and "csrftoken" orders.
But again... this is a karma the IntegrityError: datas_data.time
may not be NULL
As i say at the beginning, i feel like taking the dirty way, and
obviously not seeing something.
Regards!
