Re: upload image with Django
Can you show me an example? With the HttpResponseRedirect are forced to send the information to another page. While I need to display the image (in a window, that the user can close) on the same page that contains the form. Thanks in advance.

Setup a webserver that handles user input
Hi! I was wondering whether Django can be used to setup a webserver that can handle a user request and send a job to a backend queue. Specifically, I want to setup a frontend website through which a user enters the coordinates of protein atoms (a text based PDB file). This input is then used to perform a Monte Carlo simulation on a backend linux cluster setup with a queueing system, e.g. openPBS. The result of the Monte Carlo simulation are then sent back to the user, possibly per e-mail. I was wondering whether anybody has had any experience with this kind of setup. Thanks in advance!

Maybe you can use F objects to create the correct filters? It would be
something like:
object_list =
ObjectModel.filter(sometable__leftcolumn=F('right_table__right_column'))
and then you can use Q objects to combine two of them:
q1 = Q(sometable__leftcolumn=F('right_table__right_column'))
q2 = Q(right_table__another_column=42)
object_list = ObjectModel.filter(q1 & q2)

This is more an apache question than a django question, however I think you're missing to let the server actually listen on port 9000. Try adding a line like: Listen 9000 outside your virtualhost directive.

Re: Using Q objects vs explicit filters

> Could you include the output to highlight the differences?
I've just created a simpler test case. I've a couple models like:
class Parent(models.Model):
name = models.CharField(max_length=200, db_index=True)
class Child(models.Model):
parent = models.ForeignKey('Parent')
gender = models.CharField(max_length=1)
Now let's filter them (I'm doing this in the ipython shell):
In [11]: f1 = Parent.objects.filter(child__gender='f')
In [12]: print f1.query
SELECT "molserv_parent"."id", "molserv_parent"."name" FROM
"molserv_parent" INNER JOIN "molserv_child" ON ("molserv_parent"."id"
= "molserv_child"."parent_id") WHERE "molserv_child"."gender" = f
Now the same with a Q object:
In [13]: q = Q(child__gender='f')
In [14]: f2 = Parent.objects.filter(q)
In [15]: print f2.query
SELECT "molserv_parent"."id", "molserv_parent"."name" FROM
"molserv_parent" INNER JOIN "molserv_child" ON ("molserv_parent"."id"
= "molserv_child"."parent_id") WHERE "molserv_child"."gender" = f
So far, so good, they are the same. Now I'll replace filter with exclude:
In [16]: f1 = Parent.objects.exclude(child__gender='f')
In [17]: print f1.query
SELECT "molserv_parent"."id", "molserv_parent"."name" FROM
"molserv_parent" WHERE NOT ("molserv_parent"."id" IN (SELECT
U1."parent_id" FROM "molserv_child" U1 WHERE (U1."gender" = f AND
U1."parent_id" IS NOT NULL)))
In [18]: f2 = Parent.objects.exclude(q)
In [19]: print f2.query
SELECT "molserv_parent"."id", "molserv_parent"."name" FROM
"molserv_parent" INNER JOIN "molserv_child" ON ("molserv_parent"."id"
= "molserv_child"."parent_id") WHERE NOT ("molserv_child"."gender" = f
)
So only the second (Q based) filter in this case works for me. For the
records, this is with Django 1.2.5 in Fedora 14

Using Q objects vs explicit filters
In writing a complex filter for an application, I've found a different behavior between a filter like: Model.objects.exclude(filter1, filter2) and one like: Model.objects.exclude(Q(filter1), Q(filter2)) where filter1 and filter2 are both field lookups on related models; in particular only the second syntax yields the desired result set. Are the above forms supposed to produce comparable queryset?

Customize inlines in django admin
Hi folks, I have a problem with an admin inline form for a model having a ManyToMany field: the default is to visualize a select having as options all the instances available for that kind of model, with a plus button to create a new one on the fly. My problem is I want only to add the object created with the popup window and not to have the select with all the other instances and in the change page I only want the object instance previously added and not all the available instances for that kind of model. Is there any simple way to accomplish this? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Problem with restructuredtext filter
I have written for a personal django app (actually a blog), a new
restructured text role that allows to use TeX syntax and rendering math
formulas; the problem is that I don't want to allow this in comment. To
avoid to load the TeX related role I use the following snippet of code
where I delete the role directly by popping it from roles._role_registry
dictionary
@register.tag(name='restructuredTextWO')
def restructured_text_without(parser, token):
nodelist = parser.parse(('endrestructuredTextWO',))
parser.delete_first_token()
try:
tag_name, role_name = token.contents.split(None, 1)
except ValueError:
raise template.TemplateSyntaxError(
'%r tag requires an argument' % token.contents.split()[0])
return Without(nodelist, role_name)
class Without(template.Node):
def __init__(self, nodelist, role_name):
if settings.DEBUG:
print 'Without', role_name
self.nodelist = nodelist
self.role_name = role_name
self.role_fn = None
def render(self, context):
from docutils.parsers.rst import roles
self.role_fn = roles._role_registry.pop(self.role_name, None)
output = self.nodelist.render(context)
if self.role_fn:
roles._role_registry[self.role_name] = self.role_fn
return output
In the template I have
{{blog.title|capfirst}}
{{blog.creation_date|date:"D d M Y"}}
{{blog.content|restructuredtext}}
Comments
{% get_comment_list for blog as comments %}
{% for comment in comments %}
{% comment_entry comment %}
{% endfor %}
where comment_entry is a inclusion tag defined as
{% load markup %}
{% restructuredTextWO tex %}
posted by {{username}}
at {{date|date:"D d M Y"}}
{{content|restructuredtext}}
{% endrestructuredTextWO %}
Now, the problem is that this doesn't work if also the blog contains the
:tex: role and I don't understand why: there is something I'm missing in
how the template rendering works?
I would appreciate some hints about that.

Strange behaviour of FileField in FormWizard
I implemented a form wizard to import bookmarks from various website
or
from a file: the first form selects the type of the import and, in
case I
want to import from a BibTeX file, the second form is a FileField
where I
have to indicate the path of the file containing the reference to
parse.
In this last case, after submit the file, reappears the last form with
the
error "This field is required." and I don't understand why.
