Re: Rendering a form based on partly determined model state
Hi, not on my computet so will keep it short. Try to google "django form trick" the top result should be a blog post by colin grady. Basically what you need to do is to override the init method. ~Jakob On May 21, 8:44 pm, Joakim Hove wrote: > Hello, > > I have just started using Django - looks very promising! > > I am trying to implement something resembling a web-based shop.

Re: need help for using counter inside for loop
This is probably more a python issue than a Django issue. Also
I don't really know what it is you want to do, but you should
consider if you really need to make all these lists? Also when
dealing with dates or datetimes python can do a lot of string
conversion for you. If you want to do it the way you do it now
you should probably change the code a bit to make it more
readable, it does the same thing:
str_date_list=[]
for item in range(1,32):
str_date_list.append('%02i-05-09' % item)
I don't get why you should get an error on counter += 1
However you should get an error on
val_time2 = str_date_list[counter + 1]
when counter is 30, as you will get out of index. You dont
need to use counter though, you could just do
for counter in range(31):
But the problem will remain. As I don't know what you are
trying to do, I can't say how to best fix it, maybe you need
to add an extra item to your str_date_list: 01-06-09, that
you can assign to val_time2 the last time in your loop.

Re: Variables between Form and views
Hi
It seems your problem with dlist_choice is caused by an incorrect
you of global vars. I've not used globals much myself, but I believe
that you don't import them, but instead in every function that needs
them do a global var_name.
the other traceback seems irrelevant, but the problem you that
you haven't defined/imported choice in
ChoiceField(choices = choice, ...)

Re: change query for ModelChoiceField
This should fix it.
def __init__(self, something, *args, **kwargs):
super(ShippingMethodForm, self).__init__(*args, **kwargs)
self.fields["ship_method"].queryset =
ShippingMethod.objects.filter(something)
when you initiate the form, you do it like this:
form = ShippingMethodForm(something, request.POST)

Re: ajax cascading select boxes
Using AJAX in python/django is not much different than any other
tech. You choose an url, maybe just your form url and then you make
your normal javascript function that will post data to the url. In
the
view you can check for is_ajax(). This will enable you to catch all
ajax
requests and serve json data, while rendering the form when a normal
request comes in. The post data is in request.POST. Then you just do
normal python/django and return the states associated with the
region.
The javascript you can put in a .js file and just serve it on the
needed
page(s).
All of this is pretty well explained in the documentation, and there
shouldn't be anything our of the ordinary in this. If you have probles
with writing the javascript itself, you should probably try a
javascript list.
A good libary that makes making ajax and other javascripting easier
is jQuery: www.jquery.com You can take a look at that.

Re: ajax cascading select boxes
So CustomUser and UserDetails is a model you made for your
users? If that is the case, you probably want to hook use a
modelform instead is it makes things a bit eaiser.
Anyways in your view, the user just pops out of the blue. My guess
is that you need to do something like user = CustomUser(...).
If your form is going to stay like it is now, only having 2 districts,
you
don't need AJAX, you can just make a javascript to onclick show the
districts. If you do want to make a javascript, you need to make a
view
for it, that you can post the state to. And then return some json that
you can act upon. The easiest thing is probably to make a dictionary
and then use simplejson to return it in json format. Just return it as
a
HttpRepsonse, as you just want the raw data. You can use the
request.is_ajax() to test if the request on the url is an ajax request
or some one trying to visit the page. That way you could use the
current
url as your ajax url if you want.

Re: MySQL issues
Hi. I haven't used Django with mysql, but judging from your error it sounds like you haven't created the database in mysql. Django probably cannot create a db like it can when you use sqlite, as it's only a file anwyays. So you need to use your mysql tool phpmyadmin or whatever you use and create the db and then you can run syncdb. If that doesn't fix the problem, you have a lot more interesting problem. ~Jakob On 27 Apr., 10:33, 83nini <83n...@gmail.com> wrote: > Hi guys, > > I'm working on the tutorial onwww.djangobook.com. > I've created a database using "manage.py starapp books" then i > modified the "models.py" file to include classes where each class > represents a column in the database. then i modified the "settings.py" > file to include the following: > > DATABASE_ENGINE = 'mysql' > DATABASE_NAME = 'books' > DATABASE_USER = 'Lina' > DATABASE_PASSWORD = 'somepassword' > DATABASE_HOST = 'localhost' > DATABASE_PORT = '3306' > > and: > > INSTALLED_APPS = ( > #'django.contrib.admin', > 'helloworld.books', > #'django.contrib.auth', > #'django.contrib.contenttypes', > #'django.contrib.sessions', > #'django.contrib.sites', > ) > > should i be good to go or what? why do i get the long long long error > that ends with: > _mysql_exceptions.OperationalError: (1049, "Unknown database 'books'") > > when i try to validate the database using "C:\path to django > project folder...> python manage.py validate" > > I really need and appreciate your help. > > cheers, > Lina --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

It sounds like you don't want to leave the page while your code is running and then come back but just stay on the same page. A good option for this would be AJAX using javascript. Another way would be to use the same template. Users won't know what views function is run so more than one can use the same template making it look like they are on the same page. > On a slightly more complicated note, say multiple different pages have > a button that executes some code and then does redirect the user to > page 'foo'.

I would suggest that you send along to the view a variable containing data where to send them back and use to redirect them to the right place. I don't know if Django has an easier way to do it, but else that way is a pretty general way of doing it. ~Jakob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Search and urls
if you really wanted it like that, you could setup your url like this (r'^search/q=(?P)', ...) or you could just remove the q= for prettier urls and do: (r'^search/(?P)', ...)

Re: Dynamic Form - polls
Hi. Normally, what you are doing would work, initializing the form with request.POST. However the way you have constructed your form, you need have a poll object as well. Not only that but it should of cause be the poll that the post data is associated to.

Re: Unittests
Well the docs use camel case for tests, so figured that was the convention in Django. But the there are also some other places where Django doesn't quite follow the rules, like using _ in some of the HTML it generates. Maybe that part of the docs should be cleaned up, I always thought camel cases was a speciel naming convention for tests after reading the docs. ~Jakob On Apr 17, 10:29 pm, Alex Gaynor wrote: > On Fri, Apr 17, 2009 at 4:26 PM, google torp wrote: > > > Hi. > > You have named your test incorectly, so django won't see it as a test. > > You need to name testCamelCaseName.

Re: Queries, how to get what i want?
Hi.
Glad it worked out. You can't use [0] when using get as it retrives
an object. You can use it when you use filter as it returns a
queryset instead. That was my point, but using exclude before
get is fine aswell.

Re: Unittests
Hi. You have named your test incorectly, so django won't see it as a test. You need to name testCamelCaseName. Camel cases are probably not required but that's the convention. Try renaming your test. ~Jakob On Apr 17, 9:04 pm, Daniel Joshua Worth wrote: > If I run "./manage.py tests booking" it returns ok but says it ran 0 tests > so I'm obviously not doing something right if it's not running the test at > all.

Re: Queries, how to get what i want?
Hi.
I think the problem is that get is being run before the exclude when
you still have two results and fails as it can only handle a single
result.
In this case you can't use get but should use filter().exclude()[0] to
get
the result.

Re: Problem querying database
The two ways are pretty much the same, one picks a random
number to use for a slice, the other picks a random element in
a queryset. I would go for whatever you think is the easiest
to understand, when browsing through the code.
Also, if you're not sure that atleast 3 elements will come from
the query you would need an if statement in the randrange
version aswell.

Re: Problem querying database
What I meant was that you could do it like this
import random
sa = Article.objects.filter(...).order_by('-id')
random_choice = sa[random.randrange(2, len(sa))]
random.randrange will create a "random" number for you. Giving it
those arguments it can output a number of 2 (so the first wont be
selected) and number of articles -1 so there wont be in problem
getting a number that is too high.
This is just pure python functionality btw.

Re: Problem querying database
Hi.
You can just use the python random function, I believe it's in math,
and generate a random number in range of the number of articles.
You could do that before the slice even, and just get a random
number with min value of 2 instead.

Re: code from database in template -> <br>
Just wanted to add, the danger is not if the data is coming
from the db, as all the data, more or less will come from the db.
The problem is if the user has made the input that was saved
to the db, like the username. Marking such content with the
safe tag would make it possible for evil minded users to destroy
your site.

Re: code from database in template -> <br>
Hi There is a page for all the django template tags: http://docs.djangoproject.com/en/dev/ref/templates/builtins/ Your problem is the auto escape, you can use "|safe" to mark something safe and it wont be escaped. Doing this for user submitted data is a bad idea though, so make sure you don't make your site vulnerable for attacks before use. ~Jakob On 15 Apr., 12:52, mag_dex wrote: > Hey, > > I've gotten a following problem.

Re: Different approach?
Hi. As I'm not sure exactly what your goals with this site is, I'll be guessing a bit here. Using the admin to create customers ect, can be a solution, but having access to the admin also means having access to a whole bunch of stuff that you can mess with. You could instead make some views that will display some modelforms that you can use to create what you need. Maybe you also some some views that will display customers based per city postal code, city areas or whatever suits best. You could also add order tracking, so you can see what pizza's are selling most and see if repeat customers are buying the same (kind of) pizzas. All of these would also require views. There are lots of possibilities to extend. Also using the admin as the main part of the site should only be done, if the site is only used by very few trusted people. ~Jakob On 15 Apr., 05:40, Mariano Sokal wrote: > Well, i'm also new :) > > I've been using django for a couple of days trying to learn while developing > a Pizza Delivery Software...

Re: serving static files
Hi.
You misunderstood the docs a bit, I c/p'ed the url-conf bit here:
(r'^site_media/(?P.*)$', 'django.views.static.serve',
{'document_root': '/path/to/media'}),
The problem here that is also causing the error is that the file name
should be
a variable and not hardcoded for every file, so instead of default.css
you should
instead have (?P.*). This is part of the argument that serve
will take, which
it uses to find the right file to serve. That is why the error is
saying:
erve() takes at least 2 non-keyword arguments (1 given)
the 2nd arguement that it expect is the document root.
Hope this clear things up for you

Re: Use Python to parse HTML and integrating said script into Django
Hi. It sounds like you need to change your code structure a bit to really take advantage of Django and the possibilities it offer. If you just want to get your stuff working with Django and then nothing more, I guess you could keep it like it is, but else re factoring would be a good idea. The way django works, you want to keep the logic separated from the presentation. So basically that means, that you should keep the Python code separated from your HTML. In Django terms, we use the view to make the logic, where we can if needed, import helper functions. When all the data has been calculated, we pass it to a template, a html file where we with some Django code can insert data dynamically. It sounds like you need to grasp these things, before you really get going. about writing views: http://docs.djangoproject.com/en/dev/topics/http/views/ about the template language http://docs.djangoproject.com/en/dev/topics/templates/ about render_to_response: http://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render-to-response Render to response is common way of passing data to a template for display. Which was what your initial question was about. But I would recommend that you strip the html from your Python code and instead put the html in your template instead. That would be a more clean and Djangoish way of doing it. ~Jakob On 13 Apr., 07:24, Tonne wrote: > Hi > > I'm not too sure how to ask this correctly (not an experienced > developer so my vocab is not very accurate), but I'll try. > > I have created a Python script (collection of functions) that > generates a calendar of sorts, really just a long list of dates from a > 4 year date range.

Re: Details
Hi.
I'm guessing a bit here, not sure if it actually will make any
difference, but
try to delete the $ in the include so it'll become:
(r'^', include('p2.front.urls')),
$ marks the end of the url, so maybe that is giving you the problem.
