Django Form ChoiceField, initial not working

[Sector7B]

Hi, i have a simple form:
class StoreLocationHoursForm(BForm):
location = forms.ChoiceField(required=True)
day = forms.ChoiceField(choices=bagit_constants.dow,required=True)
time_open_hours =
forms.ChoiceField(choices=constants.hours,required=True)
time_open_minutes =
forms.ChoiceField(choices=constants.minutes,required=True)
time_close_hours =
forms.ChoiceField(choices=constants.hours,required=True)
time_close_minutes =
forms.ChoiceField(choices=constants.minutes,required=True)

there can be many locations, so in my view i loop through them to
create a list of tuples to provide a choices list for location:
Log Output of the list when im done:sl_list= [('-', 'Choose
Location'), (u'Super City', u'901 PHILADELPHIA STREET')]

the code i use to set initial is the following:

form = StoreLocationHoursForm(initial={"location":sl_list})

However my select is empty when it renders the HTML.

Thanks for the help in advance,

j

List compare is there something better than a double loop?

[Sector7B]

Hi, I probably have a common problem and maybe i'm not thinking about
this correctly, but here it is.

I'm building a store that has a product_list (class ProductList:
store, name, description) that contains .products (class Product:
name, description, price etc...)

I also have a cart that is built out of (class CartItem: product,
user, qty).

when the store page loads with the products I want to acknowledge that
the item being shown is in the cart.

So when i get the cart i have a result of [cartitem,cartitem,cartitem]
and i have a product_list of [product,product,product,...]

So the simpleton in me wants to do a double loop (cart/product_list)
and compare product == cartitem.product if so, do something.

But it seems there should be a better way to do that, and if not, do i
need to make a third list or can i put a transient field on product
like product.qty_in_cart to pass down to my page for testing?

Thanks

disregard, i didn't change my code, but my IDE did.

fyi: "python manage.py shell" actually showed me the exact error.

can't import any of my libraries inside of my app folder

[Sector7B]

**Disclaimer i'm using Django for GAE, but i really think this is a
Django thing**

Last night i had a bunch of code working, did a commit went to bed.
Got up this morning and started my django app and suddenly any library
i try to import from myapp fails with something like this:

"Could not import main_site.views.test. Error was: cannot import name
Store"

In the following mess it shows my Python Path including my working
django project folder
Python Path:['/Users/username/Documents/MyApp'...]

my imports are like:
from bagitlib import libform as lf
from main_site.models import Store

bagitlib & main_site being folders under MyApp.

I thought maybe i broke something, but i haven't changed the code, and
the failure will happen at the very first import from MyApp, meaning
if i move around the imports the fail message moves.

these imports seem to work:
from google.appengine.api import memcache
from django.utils.datastructures import MultiValueDictKeyError
import logging

Thoughts?

Thanks,
joe

Felippe, Thank you for our feedback, I've posted this question over to
the group you mentioned a couple replies ago, still waiting approval
from the moderators but if you feel like continuing this I'd
appreciate it.  It might be helpful to others in the future.

Malcom, I briefly looked over the site, very interesting, I'm going to
continue.  Thanks much.

Re: using django for google appengine, noob to both.

[Sector7B]

Thank you for your reply.  I gave it a try, and it didn't seem to
work.  The helper project (according to the introductory article) has
me using their "BaseModel", which I think is supposed to revert me
back to using Django code.  However there seems to be very little
written beyond that article, although it is a good one.  I went back
to the site, they have a google group specifically for this set up,
I'm going to post over to that group now.  Thanks again.

using django for google appengine, noob to both.

[Sector7B]

Hi, I'm using django on google appengine using this:
http://code.google.com/appengine/articles/appengine_helper_for_django.html

So I have my models, and I can load my pages and templates, and
started to do some rudimentary object creates and gets inside the
shell (python manage.py shell) and my views to get a feel for the
API.  Immediately Im coming across errors, which seem weird since
their so simple, and right out of the sample docs. (http://
docs.djangoproject.com/en/dev/topics/db/queries/#topics-db-queries)
I'm guessing i have setup or import problem?  Or I'm missing something
major with the appengine way of things, but I am under the impression
after the setup it should run the same.  Either way maybe someone can
tell me better.

Thanks,
j

Re: noob syntax question

[Sector7B]

Thanks for the feedback and the link, all good stuff!
I looked at what i had written, and I think a better way to ask the
question is:
What are the mechanics behind providing "choice_set.all()"?
For example i have a field "choice" so having "_set" (concatenated) is
that generated when i run syncdb somewhere, or is that dynamically
interpreted at runtime?
My background leads me to think there would be a choice.set().all(),
the "_set" seems weird (to me) unless its generated.

Thanks again,

noob syntax question

[Sector7B]

Hi,
In the tutorial 1.

It has this:
# Give the Poll a couple of Choices. The create call constructs a new
# choice object, does the INSERT statement, adds the choice to the set
# of available choices and returns the new Choice object. Django
creates
# a set to hold the "other side" of a ForeignKey relation
# (e.g. a poll's choices) which can be accessed via the API.

and gives these examples:
# Create three choices.
>>> p.choice_set.create(choice='Not much', votes=0)

>>> p.choice_set.create(choice='The sky', votes=0)

>>> c = p.choice_set.create(choice='Just hacking again', votes=0)

I understand what its doing, but I don't understand where the "_set"
comes from or where its resolved to.
Its probably more of a python thing than a django thing, but if
someone could provide insight, it would be much appreciate.

Thanks,
-j

Re: Problem setting up mysqldb 1.2.3c1 on Mac 10.5.8 Leopard

[Sector7B]

I had this same problem, i eventually abandoned building any of it
manually and switched to macports:
http://groups.google.com/group/django-users/browse_thread/thread/862ceed6f97acf1c/eeff8aa5fb16ca0c#eeff8aa5fb16ca0c.
If you read the thread no one agrees with me, but its working great
for me so far.  Since I'm a noob as well, it could prove a mistake
down the road.

However I did fix the build problem before i abandoned it.   I had to
make some symbolic links so that /usr/local/mysql pointed to my actual
install where mysql was installed.
riuxjg:local jgreenaw$ ls -l /usr/local/mysql/
total 8
lrwxr-xr-x  1 root  wheel  27 Jan 20 14:01 lib -> /opt/local/lib/
mysql5/mysql

so something like this:
cd /usr/local
sudo ln -s opt/local/lib/mysql5/mysql mysql

If you look in the build its actually looking for the _mysql.so file
which is somewhere in your mysql install directory.

hope it helps.

A Couple Newbie Questions

[Sector7B]

Hi, got a couple questions after the getting started.  I've followed
the tutorial and have it deployed to an apache instance locally.  But
planning out my next steps for my app, i have some questions hopefully
someone can add insight to.

1. Reading the documentation for deploying using mod_wsgi.  It says
not to use just 'settings' in django.wsgi The example has
 sys.path.append('/path/to/app/mysite')
 os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'.
 this doesn't work because of namespace path problems, my workaround
is:
 sys.path.append('/path/to/app')
 os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
My fear is that it would put multiple projects into play under /path/
to/app like /path/to/app/mysite2 etc...  The bigger question is my
solution doesn't match the examples.

2. Under the mysite project i have the polls app.  Lets say I want to
create polls-mobile, and reuse all the data and models from polls.  Do
i just import polls.poll inside polls-mobile?  Is that the standard
practice?

3. Authentication, I have read the benefits to authentication model
and using the django.User object.  I'd like to employ that into my
apps, but it seems that maybe the django.User object is more suited
for the project and not for the apps.  If my polls app is going to
require logins for usage, should i use the django.User and built in
authentication scheme or build something poll specific for security
reasons.  It seems one wrong check (e.g. superuser) and I
inadvertently allow someone admin access to the site.

4. After deploying to apache, in my virtual host i have:
WSGIScriptAlias / /opt/local/www/mysite/apache/django.wsgi.  Thinking
that http://dev.polls.com would take me right to the polls app.
However I still have to do http://dev.polls.com/polls to get to polls
app.

Thanks in advance for any info.
