Kudzu Version of SonomaSunshine
Funkiest SonomaSunshine page ever... A slim, trim 30ish MB page, leaves time for fetching a beer or some coffee. Takes about 10 minutes to watch. Yet another example of using Django to generate frilly, colorful Flash pages instead of more of that hypertext stuff... :) http://samfeltus.com/kudzu/KudzuMan.html ### http://samfeltus.com/site_index.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Looks like a bug. Reading the code, there's no chance that it's going to
work either: we simply don't do i18n processing on template tag
arguments.
It looks like ticket #4713 contains the start of a fix for this. You
might like to try that (I don't have time right this minute to review
and apply that patch, but I thought your problem sounded familiar and
there it is). I'll probably avoid using yet another reg-exp in the final
patch, but it looks close at first glance.
Once you apply that patch, you'll have to call resolve_variable() -- or
use the Variable() class if you're using a recent subversion checkout --
on the argument in order to have it translated.

i18n with custom tags
Hi
In the i18n docs it says you can pass in translations to template tags
in the following format:
{% some_special_tag _("Page not found") value|yesno:_("yes,no") %}
* http://www.djangoproject.com/documentation/i18n/#in-template-code
Has anyone got this working? I wrote a basic custom tag just to pass
the value back and it just displays _("Page not found")
any ideas?
Thanks -Dan

By the way, if this is like your example, you don't need this function
at all. You can just write
{{ model1object.model2 }}
to get the associated Model2 instance.
Not sure why I didn't write that initially. Still waking up on Monday
morning, apparently.

It's usually going to be easier for everybody if you explain your
problem with a concrete example, rather than trying to use generic names
for things. Otherwise mistakes will creep in and we (and you) won't be
able to tell.
Can you show us an example of what Model1 and the givemodel2datafromid()
method look like?
It sounds like you should be doing something simple like this:
class Model1(models.Model):
model2 = models.ForeignKey(Model2)
...
def get_model2(self):
return self.model2
Then, in a template,
{{ model1object.get_model2 }}
will be a Model2 object and you can use this further, such as
{{ model1object.get_model2.data1 }}
if "data1" is a field on Model2.
Does that look anything like the situation you are describing. If not,
what's a short example illustrating your problem?

Your form will have it's "action" attribute pointing to a URL that is handled by view2.py. Then, at the end of view2, you send back an HttpResponseRedirect that redirects the client to load the URL for view1 in their browser. This is a fairly normal form processing path.

Model and Template Problem
I have a Problem, i have one Model, which has some Data, and another
Model, which has some Data.
Let's call it Model1 and Model2! The Problem ist there is a Field in
Model1 which has an ID of a Model2-Object and Model1 has a function
that return the Model2-Object with that ID, too.
How can i call the information of the returning object from the
function in a template.
When I do it like this, it didnt work:
{{ model1object.givemodel2datafromid.data1 }}# data1 is just an
example-field
Can you solve this problem?

How do navigate through frames / framesets from a view?

Re: Is it possible to debug a view using breakpoints in Eclipse?
Hmm, that's odd. I don't know what to say except the ever-infuriating worksforme. When it doesn't work it is almost invariably because I have changed code without restarting the server, so what I'm looking at and setting breakpoints on in the editor doesn't match what's running under the debugger. I also confused it mightily one time by moving whole trees of code around without deleting the .pyc files. Other than that, it behaves as expected. Maybe double-triple check the --noreload is being recognized properly by tracing through the startup processing of it?

Re: elance'in django programmers
The other complication is that, in the United States, contractors have to include in their hourly rate the employer's portion of payroll taxes as well as enough money to pay for health insurance and other benefits that might be provided by virtue of citizenship in other countries, but which the contractor has to pay for him/herself. That tends to inflate the hourly rate of contractors compared with employees.

Re: Can't post attachment file in django test
My question on the file object was a shot in the dark based on the only thing that looked odd to me, given that the traceback information was useless. So, if that seems to be correct per the docs, then I think you'll need to get the traceback from the actual error in order to make progress. >From my original note: To see the traceback associated with the real error try setting DEBUG=True in your test settings file (I assume that works when running under the test framework? If not you'll need a 500.html that Django can find and the proper other settings to have the real root cause traceback emailed to you).

I forgot to mention the alternative: storing complex object-oriented hierarchies in SQL databases is officially a Hard Problem. It's just not a natural fit for all cases. So turn your problem around a bit and don't get stuck on one particular modelling method. Instead of storing the classes directly like this, try to think of a way to flatten your collection of classes. For example, if all of you "state nodes" can be stored in a single model somehow, then you only need to store, in addition to these models, the state transitions. Remember, state machines existed long before object-oriented programming. There are other ways to represent the same information without needing polymorphism and this might lead you to a more natural representation.

Maybe i'm asking something a lot > trivial, sorry me if that is the case. You can simulate inheritance by using foreign keys or one to one keys. For example: class Parent(models.Model): some_data = ... class Child(models.Model): parent = models.ForeignKey(parent, unique=True) ... It's not completely transparent, because you have to manually walk the link from a child back to the parent (refer to my_child.parent.some_data, instead of child.some_data as you get in true inheritance). It's also sometimes a bit fiddly to walk down the hierarchy: if you have a Parent, finding the associated Child can be fiddly. When I've done this in the past, I tend to denormalise slightly and through in a "child_type" field on the Parent model that tells me which type of child class to query. A little verbose, but you usually only have to write the "descend the hierarchy" code once and call it whenever you need it. Even when we implement model inheritance for the ORM layer, you won't get truly transparent duck-typing in any case: that is, given a Parent, you won't automatically know the type of its child because that would involve O(n) table joins (where n is the number of ancestor types of the parent -- children, grandchildren, great-grandchildren, etc), so that's an inefficient search approach (and we're not about to add extra columns just to store the descendant classes, since that breaks subclassing third-party models). So since it sounds like you are going to be taking the Parent instances and trying to access the class associated with it, it's probably worth implementing something like a child_type attribute that tells you where to look. Then when model inheritance is implemented, it won't be too much of a change to port your code across.

Could you perhaps ask your question using less buzzwords, since "the state pattern" would mean quite a few things? What are you really trying to do here?

One of my problems with the patch on #3414 is that it doesn't really give any authority as to *why* that solution is the right answer, as opposed to "it works in my case when I do this". Why is REQUEST_URL a valid fallback? Is this a special thing that is set by a particular web server? Without reference to documentation (or at least a particular product, if we are putting in a product-specific workaround), a patch isn't likely to go in because it just be mysterious black magic for future maintainers. Every time I look at that ticket, I remember that it's going to be work to try and work out what's really going on and why. So if you want the patch to go in, you could do the leg work and work out why those changes are the right ones (attach the results to the ticket). > > There doesn't seem to be a problem with FastCGI on my iBook nor on my > FreeBSD production machine; however, for some reason that I'm not > bright enough to understand, there is a problem with the simple > included server in conjunction with a server such as nginx, and > possibly others.

Re: Can't post attachment file in django test
> Is the value assigned to 'galleryfilename' really supposed to be an open

> string containing the file name.
Ok. Let's be clear. I have a form with 3 inputs:
input type="text" name="name"
textarea name="annotation"
input type='file' accept='image/jpeg' name='galleryfilename'
And in my test I need to simulate user input of with fields. So as was
written in the manual http://www.djangoproject.com/documentation/testing/,
quote:
...
Submitting files is a special case. To POST a file, you need only
provide the file field name as a key, and a file handle to the file
you wish to upload as a value. For example:
>>> c = Client()
>>> f = open('wishlist.doc')
>>> c.post('/customers/wishes/', {'name': 'fred', 'attachment': f})
>>> f.close()
(The name attachment here is not relevant; use whatever name your file-
processing code expects.)
Note that you should manually close the file after it has been
provided to post().
...
My view processes the /fotogallery/addgallery/ url with the following
way:
name = request.POST['name']
annot = request.POST['annotation']
fname = request.FILES['galleryfilename']['filename']
path = MEDIA_ROOT + "/galleryfoto/" + fname
im = Image.open(StringIO(request.FILES['galleryfilename']['content']))
im.save(path,'JPEG')
Did I miss something?
I'm using django 0.96 official release (not development version)
