So how did you save it in the first place? You don't actually want the `r`
and the single quotes, they're just for when you specify the literal in your
code. If you did
foo.regex_string = r'\d{2}'
it should come out the other side OK. When you print the string in your
console, it'll give the doubled-backslash, but that's just the way Python
displays them - it would do the same with the original raw string.

a django question about "python manage.py syncdb"
Hi, I am new to Django. I have installed Django and go t everything set up correctly, just started some easy tutorials. So when I do Django-admin.py startapp blog it creates a /blog directory that looks like thsi /blog - __init__.py - tests.py - models.py - views.py I know in Django, when you run "python manage.py syncdb", it will look through models.py, and create all the table it finds. However, I dont want to create all my tables in models.py, becaue when my proj get bigger, it is hard to maintain. Therefore, I create a subdirectory "/Models" to store all my model /blog - __init__.py - tests.py - models.py - views.py /Models - __init__.py post.py so in my models.py: (only 2 lines) from django.db import models from blog.Models import post in my post.py: (only 3 lines) from django.db import models class post(models.Model): body = models.TextField() and then when I run "python manage.py syncdb" , it doesn't create the table "post" for me.

Hi,
You are using
(?P\w{3})
but in get_absolute_url you are using
self.pub_date.strftime("%m").lower(),
referring to http://docs.python.org/library/time.html#time.strftime
%m return Month as a decimal number [01,12].
this won't never work
You should use %b instead of %m
This should work

Test DB Connection

Why does Django not pass on error messages with the default 404 view?
The docs (https://docs.djangoproject.com/en/dev/topics/http/views/ #customizing-error-views) state, "The page_not_found view should suffice for 99% of Web applications, but if you want to override it, you can specify handler404 in your URLconf". The page_not_found view only passes on the requested URL and ignores any message you provide when raising an exception. It seems to me that having the *option* to provide helpful hints to the 404.html template by default would be good for everyone. Could someone explain the reasoning here? I'm currently making a custom view, but maybe it's a bad idea in practice? A more specific context: I'm using matrix URLs so the base resource is a normal hierarchical URL followed by matrix options in the basic format of: ;filter_type1=item:value,item:value;filter_type2=item:value... So it is quite easy to provide helpful messages based on how far along the parsing gets before having an error. Wouldn't it be good to pass on a message such as the following examples? "Allowed filter_types: type1, type2, type3." or "Allowed items for filter_type a: item1, item2, item3." Apologies if I missed this explanation elsewhere.

Foreign key problem
Hi,
I'm trying to populate a table with 2 foreign keys using a csv file
and keep getting the following error :
Cannot assign "238": "PrizetoRestaurant.RestauranttId" must be a
"Restaurant" instance.
I tried to manually define the primary keys in those tables, and I'm
making sure I int() the data from the csv, but still now luck.
I've also looked in the db and a restaurant with id 238 does exist in
the Restaurant table.
I'm attaching the relevant code bellow.
Thanks!
I have the following model:
class Restaurant(models.Model):
Id = models.IntegerField(unique=True, primary_key=True)
Name = models.CharField(max_length=128)
Address = models.CharField(max_length=128)
Zip = models.CharField(max_length=128)
City = models.CharField(max_length=128)
Phone = models.CharField(max_length=128)
Latitude = models.DecimalField(max_digits=11, decimal_places=9)
Longitude = models.DecimalField(max_digits=11, decimal_places=9)
class Prize(models.Model):
Id = models.IntegerField(unique=True, primary_key=True)
Name = models.CharField(max_length=128)
GroupId = models.ForeignKey('PrizeGroup', to_field='Id')
class PrizetoRestaurant(models.Model):
RestaurantId = models.ForeignKey('Restaurant', to_field='Id')
PrizeId = models.ForeignKey('Prize', to_field='Id')
Date = models.DateField()
Quantity = models.IntegerField()
and the code is :
import csv
reader = csv.reader(open("/Users/guy.nesher/Work/tmsw/swiss/src/
monopoly/static/csv/dailydatatest.csv", "rU"), dialect='excel')
for row in reader:
PrizetoRestaurant.objects.get_or_create(RestaurantId=int(row[0]),

Django models design question
Hello everybody, I am writing my first web application with Django. I want to create a web of registration for many subjects. However, each subject require different set of details to be supplied so I don't know which models should I have in the database. Currently I have two models: Registration - describes a registration (each record is a different subject) Details - describes all the possible details which may be necessary to register. Now, each Registration instance should contain a list of the necessary details, so i guess that Registration and Details are Many-To-Many connected. My question is - how the other model(s) which contains the actual details and a FK to Registration model should look like? I don't want to create a new model for each Registration record and place the necessary details hardcoded in the model fields. What if I have 30 records in Registration table ?! -- You received this message because you are subscribed to the Google Groups "Django users" group.

I would start with a tried and successful approach and *after* getting the tables created refactor the models into separate files if that seemed to be a good idea at the time. Also my guess is that you will eventually split your project into apps as a more "natural" way to keep things simple rather than putting individual models into their own files. However it may be possible to simply delete your models.py file to get syncdb to work. I haven't tried it so I don't know.

The error is quite clear: you're getting an integer from the CSV, but
Django's ForeignKey expects an actual instance of the related table. If
you'd called your field something sensible like "restaurant" this would be
more obvious.
You can actually assign the ID directly by postfixing _id to the field name
- so in your case, it would be RestaurantId_id
Please, also read PEP8 and don't give your fields InitialCaps names - they
should be lower_case_with_underscore.

Re: Foreign key problem
Hi DR,
Thanks, I've just started developing in Python/Django so I do
apologize for the bad naming convention (I'll fix this once everything
works, don't want to add additional errors before I sort this).
Having said that I assumed that if I define the foreignkey manually
and specifically select an int field it will work.
I've tried to add the _id to the update process (ResturantId to
ResturantId_id) but I just get an error saying the field does not
exist :
Cannot resolve keyword 'RestaurantId_id' into field. Choices are:
Date, PrizeId, Quantity, RestaurantId, id
The new update line now looks like this:
PrizetoRestaurant.objects.get_or_create(RestaurantId_id=int(row[0]),
PrizeId=prizedict[2], Date = row[10], Quantity = row[2])
I'm guessing I'm missing something, just not sure what

Something wrong in the model ot template - my Christmas wishes list
Hello,
In the model I have :
def campaign(request, campaign_id):
ctx = {'camppeople': PersonPhones.objects.all() }
return render_to_response("campaign.html", ctx,
context_instance=RequestContext(request))
I also have a place where I store the info whether I want to call that
person:
class CampPeople(models.Model):
person = models.ForeignKey(Person)
camp = models.ForeignKey(Campaign)
docall = models.BooleanField(True)
called = models.BooleanField(False)
objects = CampaignManager()
The template is:
{% for piplok in camppeople %}
{{ piplok.person.label }}
{% if piplok.docall %}
dzwon
{% else %}
nie dzwon
{% endif %}
{{ piplok.phone }}
{% endfor %}
The prob;em is that there is no Django magic, piplok.docall is always
false. If you need more data I'll supply it.
Please help, I am new to Django. Thanks in advance.
Regards,
Piotr Hosowicz

CampPeople.objects.all() }
return render_to_response("campaign.html", ctx,

Re: Django models design question
Hello omerd -- If you give some concrete examples of what you are trying to do, including providing your current models.py code, it will make it easier for us to help you. Since you have Registration and Details models, I am assuming you want the user to be able to create/define these items, rather than specifying them yourself beforehand. So if I am a user of your system, I can define a new Registration for handguns, and indicate that I want Details of caliber and shell capacity. Then another user can access the system and register his .38 six-shooter. Is that the kind of thing you have in mind? If so, you are essentially giving the users the ability to define a new table (Registration) with certain columns (Details), and then letting them populate it (and you would store the actual values using another model like 'AttributeValue'). On the other hand, if you are defining the subjects beforehand as the developer, you will want a different approach altogether. In that case you might consider something like model inheritance (https:// docs.djangoproject.com/en/1.3/topics/db/models/#model-inheritance) or some other technique to keep things DRY as you add dozens of registration subjects. Hope that helps, --Stuart On Oct 14, 6:53 am, omerd wrote: > Hello everybody, > I am writing my first web application with Django. > > I want to create a web of registration for many subjects. > However, each subject require different set of details to be supplied > so I don't know which models should I have in the database. > > Currently I have two models: > Registration - describes a registration (each record is a different > subject) > Details - describes all the possible details which may be necessary to > register. > > Now, each Registration instance should contain a list of the necessary > details, so i guess that Registration and Details are Many-To-Many > connected. > > My question is - how the other model(s) which contains the actual > details and a FK to Registration model should look like?

Otherwise you need python-distribute or python-setuptools to build it (you can just install one of them with 'zypper in python-...' or download from the same[1] repo).

Re: Test DB Connection
>From what i can understand, you want to test whether you can connect to database from your django project or not. If this is your need then try the following: Go to the shell using following command: python manage.py shell On the shell, issue the following statements: from django.db import connection c=connection.cursor() I you don't get any errors, it means your DATABASE_SETTINGS are correct and you can go ahead and use your django models.

Re: a django question about "python manage.py syncdb"
I tried to delete models.py, and just have a /model subdirectory, but "pythin manage.py syncdb" doesnt pick up the models in /models directory, Do i need to change some configurations to tell Django to use /models subdirectory. Or do I need __init__.py in my /models subdirectory, I tried both, neither works.

Re: a django question about "python manage.py syncdb"
You need a __init__.py in your models.py. You also need to import all your models into that __init__.py. If I recall you'll also want to set class Meta: app_label = "the name of your package" Because the models directory will screw up Django's ability to auto figure it out.
