Re: Problem with DetailView

[Smaran Harihar]

If I am not wrong. The issue is with the List View not Detail View.

You need to provide, List View with query set. If you are providing model
parameter, you will also need to give it a primary key 'pk', like you did
for Detail View.

Hope that helps,
Smaran

Re: Model for ListView needed?

[Smaran Harihar]

Thanks for the reply Melvyn.

So by multiple model instances you mean the multiple records that poll app
has in it's database?

Re: submit parameters to py script

[Smaran Harihar]

Once again thanks for the helpful guidance Melvyn and Babatunde.

Babatunde: I will go through the links you provided and come back with new
queries.

Melvyn : Ya, I am a newbie in Django but have Web Development exp. There is
one problem when I wish to create models and queryset for connecting to the
database and that is like this,

1. My settings.py points to Postgres database, which is my main database.
2. The data I wish to extract and display in CSV, is in another database
(mysql). What I have come to know after completing the basic tutorials of
Django is that we define the database in the settings.py and since I
already have the postgres defined, how can I also connect to this MySql
Database, using views/models? This is why I wanted to trigger an external
py script which will deal with this MySql database separately.

Is there a way to connect to multiple databases simultaneously? If so then
please let me know how?

Thanks,
Smaran

Re: submit parameters to py script

[Smaran Harihar]

Thanks for the reply Melvyn and Babatunde. So my script is, using the
parameters, to search in a database and then spitting out the output back
as CSV.
I wish to return the CSV and also display the output in the table on my
html template.
Ok, so adding it to view makes more sense, but how do i connect or execute
that view, on the click of the submit button??

Re: submit parameters to py script

[Smaran Harihar]

Thanks for the reply Rohan. I am trying to create a Django App in which,
user will be adding some info in the text box and on clicking submit, I
wish to send the contents of the textbox to the py script. The output of
the py script, I wish to display it in a table on my HTML template.

I hope I was able to explain myself. Also where should I place my py sript,
which will be triggered on submitting the data.

Thanks,
Smaran

submit parameters to py script

[Smaran Harihar]

Hey Djangoers,

I am trying to execute a python script on submit button on a html file.

So i have created a view which renders a html template file and on
'submit', I wish to send few parameters to the py script.

I wanted to know,

1. where should I keep my py script?
2. I have not modified my html into Django template, but what modifications
will it need if I want to send parameters to py script on submit?

check for edited views.py

[Smaran Harihar]

Hey Djangoers,

I am messing around with a big django project and adding my view by editing
the views.py in the project code. This is the code that I have added,

def current_datetime(request):
   now = datetime.datetime.now()
   html = "It is now %s." % now
   return HttpResponse(html)

By this code you must have understood that I am a newbie. So what I want to
know, is there a way to check, If my editing the views.py has created some
error in the pre-existing project? How can I detect it?

Re: Decoupling Urls

[Smaran Harihar]

Hey Nik,

Thanks for the reply. When you say, provide full path for the lazy quoted
version, do you mean 'polls.url' ?
Is that not relative path?

Also having the path in quotes 'polls.url', is it not a string?

Thanks,
Smaran

Decoupling Urls

[Smaran Harihar]

Hi Djangoers,

I just completed the tutorial 3 and got a little confused on the last
section<https://docs.djangoproject.com/en/dev/intro/tutorial03/#decoupling-the-urlconfs>of
the tutorial,

urlpatterns = patterns('',
url(r'^polls/', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),)

In this for the polls app, we are assigning the urls.py path in the quotes
'polls.urls'
but for admin we are not?

So what is the difference and being it quotes how does it still pick up the
path? Does django not consider it to be simply string.

Raise 404

[Smaran Harihar]

Hey Djangoers,

I am on my tutorial 3 and I was on this
topic<https://docs.djangoproject.com/en/dev/intro/tutorial03/#raising-404>
.

And now if I try to access http://localhost:8000/polls/1/ it gives me the
same error page, which it gives for other errors.

I know the error is because I have not yet created the detail.html page but
is this the output for 'raise Http404' ?

Tutorial three '-pub_date'

[Smaran Harihar]

Hey Djangoers,

I am on the tutorial
3<https://docs.djangoproject.com/en/dev/intro/tutorial03/#write-views-that-actually-do-something>,
and found this code where we are modifying the view index()

def index(request):
latest_poll_list = Poll.objects.all().order_by('-pub_date')[:5]
output = ', '.join([p.question for p in latest_poll_list])
return HttpResponse(output)

What I did not understand, was why did we state,

order_by('-pub_date'), what does that *'-'* mean before 'pub_date' ?

Same virtual-env for all django projects

[Smaran Harihar]

Hi Djangoers,

I am using virtual-env for my django project and I wanted to know that is
it ok to use the same virtual-env for all the django projects on my system?

or do I need to create a virtual-env for every other django project?

So what I am doing is that I have the virtual-env dir in my folder django
and I have just started my project on Django called mysite (following the
tutorial). So now if I wish to create a new django project, can I again do
`source django-env/bin/activate` and then create the new app?

or new dir and new virtual-env??

Foreign Key needs quotes?

[Smaran Harihar]

Hi Djangoers,

I am following the tutorial and found something I am not sure if is right
or wrong? So here is my question,

In the tutorial 01 where we need to create two models in
models.py<https://docs.djangoproject.com/en/dev/intro/tutorial01/#creating-models>,
we are providing the ForeignKey to the 'Choice' model for 'Poll' model
without quotes,

class Choice(models.Model):
poll = models.ForeignKey(Poll)


But when I went to read about Foreign key a bit more in
detail<https://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ForeignKey>,
I found that the model 'Car' is being given the 'Manufacture' ForeignKey in
quotes,


class Car(models.Model):


manufacturer = models.ForeignKey('Manufacturer')


So I wanted to know, which is the right way to go or it does not matter?

unable to connect freenode

[Smaran Harihar]

Hi guys,

I was going through the first step of the tutorial where I found this,

Where to get help:
If you're having trouble going through this tutorial, please post a message
to django-users or drop by #django on irc.freenode.net to chat with other
Django users who might be able to help.

And so I tried clicking on the link where it said #django on
irc.freenode.net and then I get a popup of application launching which will
connect to the freenode.net for #django channel and I ok it, but then
nothing happens.

Am I doing it wrong? I am on Ubuntu.

locating the functionality behind the HTML element

[Smaran Harihar]

Hi Guys,

I am new to Django and have completed the initial basic tutorials in the
django doc. I am presently working on a pre-customized django application.
I was wondering how I can use FireBug to locate the code in a specific
element (like button). In the sense, in general the web development once we
are able to locate the button we are able to then locate the class of the
specific element and JS attached to it and CSS. But in Django this cannot
be done since everything is located in separate directories.

Since I am entering into the Django code, where should I start looking for
the CSS and JS files?

Re: interpretting urls

[Smaran Harihar]

Going thru the doc link you gave, I did not understand the term middleware
request processing?

but if the incoming HttpRequest object has an attribute called urlconf (set
by middleware *request
processing*<https://docs.djangoproject.com/en/dev/topics/http/middleware/#request-middleware>),
its value will be used in place of the
ROOT_URLCONF<https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-ROOT_URLCONF>
 setting.

interpretting urls

[Smaran Harihar]

Hi,

I am bit confused about what exactly do these urls imply in the url.py

urlpatterns = patterns('',
 (r'^(?:index/?)?$', 'geonode.views.index'),
(r'^(?Phelp)/?$', 'geonode.views.static'),
(r'^developer/?$', 'geonode.views.developer'),
url(r'^lang\.js$', 'django.views.generic.simple.direct_to_template',
   {'template': 'lang.js', 'mimetype': 'text/javascript'},
'lang'),
(r'^maps/', include('geonode.maps.urls'))


I know that a simple url syntax like this,

url(r'^data/$', 'geonode.maps.views.browse_data')

implies, that it will execute the function browse_data in views.py in the
maps directory, inside the geonode dir.

But not sure what the above urls imply. I am absolutely new to Django so
can u explain in simple terms.
