Re: help to finish my 1st Django app.
Hi Igor.
Thanks for your reply. My poll_list.html code is:
{% if latest_poll_list %}
{% for poll in latest_poll_list %}
{{ poll.question }}
{% endfor %}
{% else %}
No polls are available.
{% endif %}

Re: URL design for security?
Thanks for the replies. No, I haven't incorporated authentication yet. I guess I was thinking that even if the user was logged in, the URL still would be showing potentially sensitive info. I was thinking maybe I needed to create some random sequence of letters/numbers, store that in a model field and use it as the pk which would then up in the URL params. Probably overkill with my limited experience. I'll take a look at the authentication module and try some tests. Thanks again.

URL design for security?
Hi, I'm starting to write a grade book type application. There will be many teachers that will be logging in to access their student records. The student record will contain student grades and sensitive info such as student ID number. In the model each teacher will have a primary key (pk) and each student will have a primary key. So if teacher (with pk=21) logs in and wants to update the grade for student (pk=197), the URL I'm calling to retrieve that view is "/grades/ 21/197" (ie, on the teacher page there would be a list of student names each being an as shown). I feel like by using this scheme I'm giving away too much info in the URL. Some other teacher (or person) who is NOT teacher (pk=21) could just enter that URL and look at some other teacher's grades just by "guessing" what pk to plug into the URL. What if the student pk was actually his SSN, then I wouldn't want that as part of the URL for sure. So my newbie question is: Is there a way a better way to design/ obfuscate the URL scheme when dealing with sensitive information? I know once I get some sort of authentication in place that will help, but the idea of showing sensitive info in a URL still has me concerned. Thanks in advance.

Re: Eclipse and PyDev setup
Hi, I'm a newbie as well, but have a project I developed using Eclipse and Pydev. Bascially, I just unchecked the "Create src folder" option for the Pydev project and all seems OK so far. Can't help with Apache yet as I just use the Django builtin server from within Eclipse and start/stop the server there.

Thank you so much! I was able to get your first method to work. The second method seemed to be complaining that I was using a for-loop on an empty "photo_set". I'll play around it some more.

NEWBIE: joining two tables problem
Hello. Newbie to django and first-time poster to this group.
I've got two models (basic structure shown below):
class Employee(models.Model):
name = models.CharField(maxlength=50)
office = models.CharField(maxlength=20)
phone= models.CharField(maxlength=15)
class Photo(models.Model):
filename = models.CharField(maxlength=50)
master_photo = models.BooleanField()
employee = models.ForeignKey(Employee)
In one of my views I'd like to have a table consisting of rows like:
but if I say:
object_list = Employee.objects.order_by('name')
and pass "object_list" to my listing.html template, it doesn't have
the Photo information.
I've resorted to using straight SQL to build the query:
def employee_view_list(self):
from django.db import connection
cursor = connection.cursor()
cursor.execute("select e.id, e.name, e.office, p.filename
from company_employee e, company_photo p where p.employee_id=e.id and
p.master_photo='T'")
rows = cursor.fetchall()
return rows
This sort of works and returns a list-of-lists, but I can't use the
convention {{employee.name}} in the
template since the returned rows do not include the header
information.
Questions:
1) Is there a better way to join these tables using the django model
methods?
2) Is there an better way to use straight SQL and still be able to use
things like {{employee.name}}
in the templates?
3) I tried making the Photo table have a "many2manyfield" on Employee
rather an
a ForeignKey. I rebuilt the database using syncdb, but when I tried
to enter photo info
via the admin interface, I got an "operational error". I could edit
the other database tables
fine. Ideas? I tried using the latest stable django and the SVN from
today with the same
result.
Thanks in advance.
Rogelio
