Re: pub_date timezone

[BrendanC]

Hi erm
 
I put that line in and still won't work. In my models.py file I have the 
following:
 
from django.db import models

class Poll(models.Model):
question = models.CharField(max_length=200)
put_date = models.DateTimeField ('date published')
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes =models.IntegerField()
 
After I entered import Poll the following would not run
python manage.py shell
When I removed it as seen above, the shell ran but the timezone issue still 
existed.
 
Thanks again for your help
 
Thanks for this advice. I did import

Re: pub_date timezone

[BrendanC]

Hi erm
 
Went back over your comment and realised what you commented. 
After python manage.py I gget the python prompt>>> and then typed
from polls.models import Poll, Choice
 
then I typed: Poll.objects.all() and got the array brace [] returned.
then I typed from django.utils import timezone
 
then typed: p = Poll(question="Whats new?", pub_date=timezone.now())
This line will not run and tells me pub_date is an invalid argument.
 
Thanks again in advance

Re: Dynamically form modification - Is this possible?

[BrendanC]

I was hoping to use ajax and a customizable template with the additional 
fields that I'd added dynamically and then somehow update the form class 
with the info required to support form validation (however I'm not sure that 
this approach will work - I can get the initial display to work, but not the 
validation as the form class knows nothing about the additional data 
fields).  This approach would eliminate the need to enable client/browser 
Javascript.

Re: Dynamically form modification - Is this possible?

[BrendanC]

I'm still not clear on how/whether it is possible to MODIFY the form once 
it's been initially displayed  - the __init__ method is invoked when the 
form is first created/constructed - what  I want to do is rerender/redisplay 
the form with new fields after it's initial display -since the form need's 
to 'self modify'.

Sorry for any confusion here, but I just want to understand/explore all the 
options.

Dynamically form modification - Is this possible?

[BrendanC]

Is there away to dynamically modify and validate a Django form AFTER it's 
been created and displayed. I have a form where I want to display and 
validate additional input fields based on the selection from a dropdown on 
the initial form.

(I have found a few snippets that show dynamic form creation, but these 
require that the dynamic fields are known/defined prior to creating the 
form.)

Displaying a User Confirmation (Flash style) Message after a redirect - How?

[BrendanC]

I see that the an upcoming will include a new messaging framework to
display custom user messages - I think this is designed to mimic ROR.
See:http://docs.djangoproject.com/en/dev/ref/contrib/messages/

In the current release V1.0 or 1.1 what is the recommended approach?
On a successful save I want to redirect the user to a new page, then
display a save confirmation message that includes the ID of the new
record. (I'm thinking of using a session object, but there appear to
be some pros/cons.)

Links to examples would also help.

TIA
BrendanC

Re: How to pass context with a form?

[BrendanC]

Replying to my own message - problem solved - ignore previous posting!

I forgot to include my variables in my response
so expected values were not being passed - I was doing this:

variables = RequestContext(request, {
'form': form,
'caller': caller,
'error': error
})

   return render_to_response('search.html')

instead of:

variables = RequestContext(request, {
'form': form,
'caller': caller,
'error': error
})

return render_to_response('search.html', variables)

Just another brain fart at my end. Sometimes I just can't see the wood
for the trees!

How to pass context with a form?

[BrendanC]

I have a reusable search form and want to display a different form
header based on where/how the search is called from (I get this from
the url). In the search template I'd like to test a variable to
determine which header to display. I need to somehow pass variable
from the view the template - something like this:

form = SearchForm({'Retired' :'Retired Staff''})

then in the search template check the Retired variable :


{% if Retired %}
  Search Retired Staff List.
{% endif %}


The generic search form class is"
class   SearchForm(forms.Form):

# Create a Search Form - set form header to value passed by
caller

query = forms.CharField(
label=u'Search by Employee ID ',
widget=forms.TextInput(attrs={'size': 32})
)

The catch here is that the variable is not a field on the form. So how
can Ito pass context info at form creation time? Is this possible?
