memcached + multiple virtual hosts

2006-02-09 Thread Roberto Aguilar


Hello,

I'm planning on running multiple websites on one server using virtual
hosts.  I also want to run memcached and wanted to know what the best
way to avoid "name collisions".

Would the right thing to do be run multiple instances of memcached on
different ports, or does memcached somehow account for many virtual
hosts?  I've tried googling for multiple memcached instances, but have
not had any luck.

Thanks!
-Roberto.

making email required

2006-02-09 Thread char



I'm just wondering what the best way is to make User.email a required
field. I wouldn't think I'd be required to modify django's source but
I'm not sure.

So this is a strange problem...I'm getting the Following error when try to

I think the whatever constructs the SQL interface is doing something 
wrong.. 
Below is the output of the SQL it tries to contstruct..

I think that it has something to do with it leaving out the 
contrack_locations in the query it constructs. 
Also below you will find my classes for the query in question.

OneToOneField extending User: is this the best way?

2006-02-09 Thread arthur debert


Hi folks.

I realize this is a recurring question on this list but I have not
found an authoritative answer, maybe some one can show me the best path
to take.

I want to add new fields to a User class.

should I:

1) extend from auth.User as described in the wiki. This seems nice, but
I feel like fiddling too much into django internals doing it. Should I
be afraid?

2) with a one to one relationship. This seems less threatening but,
while trying to implement this, I don't know:
a) how do I specify, in the admin, that users should be edited inline,
is this possible at all?
b)how to access user fields from the container class's admin, such as
this:
class UserContainer(meta.Model):
#our contained user
user = meta.OneToOneField(User)
# add any additional info here
user_is_mad = meta.BooleanField()

class META:
admin = meta.Admin(
# HERE: how do I access user's first_name?
list_display = ("user.first_name", 
"user_is_mad"),
)

I am sorry if there are typos on this code, I am just trying to
provide am example...

Any thoughts on this?

Thanks a lot,
arthur

p.s.: I guess after the new admin branch is merged it will be trivial
to subclass user but I have an app to deliver sooner than that so...

integer field's type?

2006-02-09 Thread sam


I observed a weird thing with the integer field defined inside a model
class. Suppose I have

SEX_TYPE_CHOICES = (
(1, 'male),
(2, 'female'),
)

class Person(meta.Model):
sex = meta.Integerfield(choices=SEX_TYPE_CHOICES)
def is_male(self):
if self.sex == 1:
return True
else:
return False

The problem I have is if I try this method is_male() under django
python shell, it works perfectly fine. But it always fails when invoked
from web "views". I have to change self.sex ==1 to self.sex == "1". Did
I miss something completely or is it a bug?

Julio, with all due respect for your programming prowess, I *like*
recursion.  It can often make hard problems easy, even when generating
HTML.

Anyway, I figured out how to solve the problem *using recursion*, and
I blogged about it:

 It works, but it's nowhere near as elegant as simply being able to

I'd be happy to write this up once I get it working. The problem I'm
having right now is that there seems to be no elegant way of updating
the dictionary bound_related_object_overrides in admin_modify.py to let
it know about additional view types. I can, of course, edit it directly
in admin_modify, but this isn't very nice.

Any suggestions? All ideas I can come up with involve changing the
admin code.

Re: editing multiple records

2006-02-09 Thread Jason Huggins


Patrick,

I'm using Django right now for my in-house Finance department to "bulk"
edit multiple items. You'd be surprised how I'm doing it, though. I'm
generating an XML file and letting the user download it from the
website... Then they use Excel for the "bulk editing", save again as
XML, and repost back to the server. I'll document blog/this when I'm
done. I *could* try to emulate the bulk editing features of a
spreadsheet with something like TrimSpreasheet
(http://trimpath.com/project/wiki/TrimSpreadsheet), and I hope to do
that someday... but those "real world" finance dept. employees prefer
the Excel interface... So "let them have cake", I say! By limiting the
use of Excel to its strong GUI features for bulk editing (filters,
sorting, searching, etc). I get the best of both worlds. And after the
users are done, the results get posted back to a nice, clean,
normalized relational database. No yucky spreadsheet files with
massively important un-auditable data lying around on everyone's hard
drives. Everyone's happy, and best of all Django makes this pretty darn
easy to do, with the help of ElementTree for the XML.

The overrides stuff is just to allow TABULAR and STACKED to continue to
work, without meaning that the core django has a dependency on the admin
code.

  As you are defining your own class, that shouldn't matter for you, you
can just use the class directly, eg

from path.to.custom.admin.code import MyBoundRelatedObject

class Whatever(Model):
parent = ForeignKey(edit_inline=MyBoundRelatedObject)

I really didn't document this very well at all. It would be great if you

Thanks for answering so fast.

I didn't see this anywhere, but I didn't understand how it is supposed
to work after reading
http://www.djangoproject.com/documentation/db_api/#many-to-one-relations
(just behind the one-to-one part, but obviously not working in a

assumptions about fields etc. which Django does; being a Django newbie

Did you read the line:

Inline editing can be customised. rather than using
edit_inline=meta.TABULAR or meta.SOURCE, you can define a custom inline
editing mode. This is done by subclassing BoundRelatedObject?, and using
that class. eg edit_inline=HorizontalScroller?.

You can look at the implemention of TabularBoundRelatedObject to see how
to do it. Basically, override the template_name() method IIRC.

Re: truncate html filter?

2006-02-09 Thread Luke Skibinski Holt


It's probably not ideal for your needs, but I put an 'abstract' (or a
'short_desc') field for user's to enter a summarization of their data,
then use the abstract with the list views to link to a more detailed
view - it depends entirely on one's situation though.

You could of course just strip out all embedded html in a truncated bit
of data and list that

stripped = striptags(data[:truncate])

where striptags() is your given html cleaner of choice ;)
I've generally had good dealings with the python interface to html
tidy, but is occasionally returning nothing at all with no error ... it
also feels a little unwieldly, but I'm shopping about for another
solution - Beautiful Soup looks promising.

Re: Tiny myce

2006-02-09 Thread akaihola


Doesn't your HTML render as expected in the editor, or do you get
unexpected results when viewing the resulting HTML outside admin? If
you're used to hand-coding your HTML, remember that with wysiwyg
editors, your HTML is not your HTML anymore: you'll have to live with
the machine-generated markup.

The colors links made with tiny_mce will follow the current CSS
definitions. You can use Firefox and the Web Developer extension to
take a closer look at what's happening at the html/css level.

I got good results by following these guidelines when pasting stuff
into tiny_mce:
- do all formatting in CSS
- no formatting attributes in HTML, only id= and class=
- strip all extra tags and attributes in tiny_mce

In my textareas.js, I made the following changes compared to the django
howto:
theme_advanced_buttons1 :
"fullscreen,separator,formatselect,bullist,undo,redo,separator,link,unlink,separator,cleanup,code",

plugins : "save,fullscreen",
valid_elements : "a[href|title],p,br",
invalid_elements : "font,span",

This way my HTML keeps relatively clean and I get good results even
when copy-pasting from word processors. Of course, I add more valid
elements when I see a real need for them.

I also like the stripped-down user interface. No extra buttons, only
add new ones when they're really needed.

That was going to be along the lines of my solution if I didn't get a

I was going to use microdom (have had some trouble with html tidy in
the past) and maybe some xpath, xsl or similar to sort out what is
what. Am a little concerned about performance, if I'm truncating 50
