Re: How to implement this fucntionality ? (current page higlighting)

[coulix]

Giving each menu item an id : OK
"and in each section of the site, assign a class to
the body tag based on the section you're in."

i cant't do that i use a template which follow this way :
---


[...]



{% include "header" %}
{% include "menu" %}
{% block content %}{% endblock %}
{% include "footer" %}

The only part gettng updated when i go to contact or other, is the
block content,
so unless i start to also change the menu style for each link i dont
see how.

if i a m wrong a example would be nice,

how to implement RequiredIfOtherFieldEquals validation?

[gizo]

Hiya.

I am completely lost. I want to use the standard AddManipulators
provided. They are cool.
But, I also want to make use of the RequiredIfOtherFieldEquals
validator from django.core.validators.py.

I have searched and searched, but I can't seem to find any reference to
how to implement it (or any of those validators..?)

i have tried adding it in the view like this:
manipulator.fields[3]=formfields.IntegerField(field_name="monthDay",validator_list=[
RequiredIfOtherFieldEquals("periodType","Month")]
and in the model like this:
monthDay = meta.IntegerField(null=True, blank=True,
validator_list=[RequiredIfOtherFieldEquals('periodType','Month')])

and I've tried prefixing with "validators."

Am I trying to do something which can't be done? And if not, how do I
access and use all those validators?

Lost in confusion, 
gizo.

Re: filter object_list in generic views

[char]

Sorry for the bump. I'm still trying to figure this out. The
extra_lookup_kwargs field of the info_dict seems like it comes close to
doing what I want to do but I can't drive it from a search form so I'm
still stumped. Do I really need to make a custom view if I want to
filter the list results via a search form? Thanks, any help would be
appreciated.

If those files change on a flatpage-by-flatpage basis, you might be
better off making your own version of Flatpages with fields for the
CSS/JS locations; you could then pass those into the template as
appropriate.

You could clone Flatpages for the other file types and ForeignKey each
flatpage to a CSS entry and a Javascript entry; make sure you consider
the potential performance issues if you go that route, though. 
(There's a reason people tend to serve CSS and Javascript from static
media servers even if the site itself is dynamic.)  :-)

Re: generic views - object_detail and info_dict

Thanks... for some reason, I had the perception that the urlpatterns
specified the template not the view.  Knowing it's the view I went
to the source code and now understand.  It's amazing how one reads
things when you have an incorrect perception to begin with :-)

Perhaps that might need to be more clear in the docs?

Except that it's not IN the docs... :-)

At least, searching for "_detail" did not show any such explanation.
The docs for archive_ all have a line like:
   "Uses the template app_label/module_name_archive_day by default."
but the description of object_detail (for both date_based and list_based)
does not have anything to say how the template name is derived.

On a related note... I find it a bit confusing to see something like
"module_name_archive_day" to mean (in my syntax)
"_archive_day" (i.e. the contents of the variable named
"module_name" will be followed by the string "_archive_day").

What with so many things taking 'variables' and strings and combining
them, I would suggest SOME demarcation in the docs when using the name
of a variable in a string along with other characters.  For me,
placing a variable name between <...> is clear since that doesn't show
up as real text, but something is really needed for clarity.  In part,
this did add to my misunderstandings.

Yes I do. But I can not found something relative to my question. And
if I test the model it is no promblem at all. Just like:

say a = UserProfile object

when I use a.user is no problem.

But if I click UserProfile in admin, the error is complained. So I can
only see the UserProfile model in the first page of admin, but I
cannot go into it.

I'll check bug reports carefully.

Thanks.

i understand that, but the problem is that such thing is quite hard to 
integrate into the admin-framework.

because i do not control the model (the model is django.models.auth.users).

my previous solution was like you mentioned. i had my own view, with all 
the code entered, but i kept fighting with things like the history for 
the model object, permissions, custom links in the admin-index-page, 
things like that.

in other words, the current solution (javascript based) is an 
implementation-hack, but integrates cleanly with the admin-framework. 
the old solution was a clean implementation the integration of which was 
a hack :))

but if you have an idea how such a custom view can be nicely integrated 
into the admin-framework, just tell me (i still have the sources for 
that view).

Don't do that.  Calculate the password hash on the server side.

You're trying to do something in the template that ought to be done in
the view.  So write a view that does what you want, rather than trying
to use client-side code to generate stuff to be sent to an existing
view.

i am not relying on client-side validation... in fact i am not doing any 
(well, a little) validation on the client side.

here's the deal:

django, admin interface.

i wanted to have in the user-manager form a way to do the normal 
password-thing (2 password fields, check if they are equal, and so on).

so, i created a page-template, put it to the right place so that it 
overrides the django-users-manager template,
and started some javascript hacking :)

i added the password fields to that page, and used javascript to:
-when submitting: check if the 2 passwords are equal, and if they are, 
calculate the password-has, set it into the password-hash input-field 
(which i made hidden), and allow the form to be submitted. otherwise do 
not allow the form to be submitted.

but if the user has javascript disabled, then the password-hash will not 
  be calculated, the hidden password-field will not be populated, and he 
gets an error message which he will not understand because it is about a 
form field that is not visible :))

i know that this is a hack, but if you know a cleaner and/or simpler way 
to have sane password-handling in the admin-interface, tell me :)

ps: (page-template attached. yes, it's quite ugly :)
ps2: i'm only overriding when the user is not superuser. superusers get 
the "standard" user-manager page.

best regards,
gabor farkas

Re: generic views - object_detail and info_dict

Glenn,

The 'archive_day' you see in urlpatterns is the name of the view, eg.
django.views.generic.date_based.archive_day and not some string that's
appended to the module's name. The default template names for date
based views happen to be the same as  the name of the corresponding
view. The default template name for the object_detail view is
_detail, so in this case entries_detail.

See
http://www.djangoproject.com/documentation/generic_views/#using-date-based-generic-views

You need to specify the hostname and port with runserver.

i.e. python manage.py runserver hostname:port

It defaults to 127.0.0.1.

Re: prefill admin forms

[Dodger]

Hi David,

I have a solution for you that works for everything except ManyToMany
fields (I believe).  If there's an easier way to do this, I'd love to
hear about it, and if anyone has an idea how I could push further to
tackle ManyToMany fields I'd love to hear it.

from: /contrib/admin/views/main.py copy "def add_stage" to your view
(renaming it would probably be smart - I called mine addMainPage).

in your urls.py add something along the lines of:
(r'^admin/mainpage/(?P[^/]+)/add/',
('fashion18.views.addMainPage')),

(notice here that I've hard coded "mainpage", so in "def add_stage" I
also hard coded app_label:

def addMainPage(request, module_name, show_delete=False, form_url='',
post_url='../', post_url_continue='../%s/', object_id_override=None):
 app_label = "mainpage"

between "# Add default data" and "# Override the defaults with GET
params, if they exist" add what you need to, in mine the important part
looked like:

new_data.update(dict({"subscription":latest_page.subscription,"poll_id":latest_page.p

oll_id,"button_ad_id":latest_page.button_ad_id,"win_id":latest_page.win_id,"online_only":latest_p
   age.online_only}))

Since no object has been created at this point, I'm unable to copy the
data for the ManyToMany field (or, I suspect, a ManyToOne field).  If
anyone could point me in the right direction for copying the ManyToMany
relationships for the new object I'd appreciate it.

For your author example, you could simply modify the add function to
accept your author object (or just the field you need), then manually
set it like I have (and yours would probably be quite a bit easier).

Cheers,

John

No, it can be used publicly. I've run it on Dreamhost and accessed it
from home, as have outside clients. You'll need to remember to use a

some django how-to-do-this queries

[Alan Bailey]

Hi there,

In my existing application, I have a user object/table to track all of our
users.  Users optionally have a foreign_info object with them too, if
they are foreigners.

So it's a one-to-one relationship.  Here's simplified:

class User:
userbase_id = ... the primary key
lots of other fields

class ForeignInfo:
userbase_id = ... also primary key
lots of other fields

My current goal is making the admin page look like I want it to, and I
want to be able to look at the foreign information while editing the user
object.

In my current framework, I had a functionality for a ForeignField, in the
User class, so the foreign fields simply appeared as fields in the User
object.  Is there a way to do that in django, something like:

class User:
country_of_birth = ForeignField(ForeignInfo)
passport_number = ForeignField(ForeignInfo)

So then it just gets the field from the other object.  Right now it just
seems that I can do:

foreign_info = OneToOneField(ForeignInfo)

But then there's weirdness because it expects foreign_info_id to be the ID
field.  Is there a way to get around that, because that's a pretty huge
assumption??  For existing applications.

The difference between this and the Place/Restaurant example on the
website is that I never care solely about the ForeignInfo, it's only as
additional information to the "parent object" User.

And then how on the admin site do I make the foreign information editable
along with the User object?  I want it to look like the Poll/Choices
example in the tutorial, but that's of course with a one-many relation.
It can look like that but with num_in_admin=1.

I'm using the magic-removal branch.  Speaking of, does num_in_admin
work differently in that branch?

Thanks
Alan

mod_python & devserver & apache restart

[patrick k]

1. is the django development-server only meant for local use? i´m asking
because i tried to use it with dreamhost and it doesn´t seem to work.

2. with using apache/mod_python in production, one has to restart apache
when changing stuff (e.g. models). with my current customers, there are
changes almost everyday. would you still recommend using mod_python? (sorry,
but i don´t have much experience with any apache-issues)

thanks,
patrick

generic views - object_detail and info_dict

[Glenn Tenney]

After the tutorials I was looking over the source code for the djangoproject.com
site.  

(1) in djangoproject.com/apps/blog/urls/blog.py I see:

from django.conf.urls.defaults import *

info_dict = {
'app_label': 'blog',
'module_name': 'entries',
'date_field': 'pub_date',
}

urlpatterns = patterns('django.views.generic.date_based',
   (r'^(?P\d{4})/(?P[a-z]{3})/(?P\w{1,2})/(?P\w+)/$', 
'object_detail', dict(info_dict,
 slug_field='slug')),
   (r'^(?P\d{4})/(?P[a-z]{3})/(?P\w{1,2})/$', 'archive_day', 
info_dict),
   (r'^(?P\d{4})/(?P[a-z]{3})/$', 'archive_month', info_dict),
   (r'^(?P\d{4})/$', 'archive_year', info_dict),
   (r'^/?$', 'archive_index', info_dict),
)


(2) And in djangoproject.com/templates/blog/ are the files:

entries_archive.htmlentries_archive_month.html  
entries_detail.html
entries_archive_day.htmlentries_archive_year.html


I see how "archive_day" (or month or year) gets converted to
"entries_archive_day", but I have no clue how / why / when
"object_detail" gets converted to "entries_detail".  For consistency I
would expect to see just "detail" in urlpatterns and THAT gets the
module_name prepended, but I don't see how the "object" part gets
dropped but the "archive" part doesn't.   ???

Unless they, say, save it to disk, edit it, reopen it, and submit the
form.  Which would be a perfectly logical thing for a user to do when
presented with a trivially broken form that they legitimately want to
submit.  I know you know that you can't rely on client-side
validation, but I just want to say, you _really_ can't rely on
client-side validation.

Calling an OtherField-style validator on an inline/stacked field

[Zanchey]

Hi everyone,

I've had a good search on the web, the wiki and the list archives, as
well as asking on IRC, and I'm yet to come up with a good solution to
this problem.

Basically, I'm trying to run a custom validator on a field which is
part of a model linked by a ForeignKey and set to
edit_inline=meta.STACKED.

The custom validator is almost completely the same as
RequiredIfOtherFieldDoesNotEqual, but is posted at the link below just
in case I've missed something obvious.

I am trying to attach this validator to a field which is part of a
model (as seen in the link below) that has a ForeignKey relationship to
another model (representing a person), and that can be edited from
within the parent model's admin pages.

However, in order to get this validator to run, I have to pass the
other_field name as 'parent.n.child' - in this case, payment.0.method -
in order to get the validator to run correctly. I don't have a way to
pass the field name without the number, and I'm not sure of a good way
to derive it (how can I tell which number this payment is?).

Google will no doubt mangle my code beautifully, so if you've got any
idea what I'm on about I'd really appreciate it if you could have a
look at http://django.pastebin.com/565256

Thanks in advance,

David Adam

Re: How to implement this fucntionality ? (current page higlighting)

[Wilson Miner]

You can also do this with CSS and not change your navigation HTML at
all. Just give each of your navigation items an id (#nav-about,
#nav-contact, etc.) and in each section of the site, assign a class to
the body tag based on the section you're in.

Then you can create CSS rules for the "current" section something like this:

.about #nav-about, .contact #nav-contact { font-weight:bold; }

Admin list filters / searches on foreign keys?

[Daniel]

Hello list,

Newbie question: I wonder how I can filter or search lists by foreign
keys. Assuming a 0.91 model like:

class Country( meta.Model):
name  = meta.CharField( _("Name"), maxlength=255)

class City( meta.Model):
name  = meta.CharField( _("Name"), maxlength=255)
country   = meta.ForeignKey( Country)

I would like to either search the city list by country, or to filter
it. The difficulty here is that searches assume CharField behaviour, so
just adding search_fields = ('country', ) predictably fails. Adding a
list_filter has no effect whatsoever.

Assuming that we have several thousand City rows, list drill-down
becomes crucial for usability. (For the hypothetical example above,
probably inline editing would be sufficient.) A hackish way of making
the search work is to replace the table with a view and throw in some
Postgres rules to handle inserts/updates etc. This works OK but it
looks terrible and is hard to maintain because the Django DB magic
cannot be used. Any other solution?

A related note: When adding foreign keys to the list_display, sorting
by clicking on the column header appears to be in order of the
*numerical* foreign key rather than the display name. Any ideas how to
get around this?

Bug report [admin]

[limodou]

I have some model just like:

EDITOR_TYPES = (
(1, 'Text Editor'),
(2, 'Rich Text Editor'),
)

class BlogProfile(models.Model):
blog_editor = models.IntegerField(_('Editor'), choices=EDITOR_TYPES)
blog_name = models.CharField(_('Blog name'), maxlength=100)
blog_short_description = models.CharField(_("Blog's short
description"), maxlength=100)

def __repr__(self):
return self.blog_name

class Admin: pass


class UserProfile(models.Model):
user = models.OneToOneField(User)
portrait = models.ImageField(_('Photo'), upload_to='photo', blank=True)
joined_groups = models.ManyToManyField(UserGroup, blank=True)
blog_setting = models.ForeignKey(BlogProfile)

def __repr__(self):
return 'user profile'

class Admin: pass

And manage.py install user_profile is ok. But as I enter admin and
click user_profile, I got an exception:

Exception Type: OperationalError
Exception Value:no such column: auth_user.username

And I check the sql that created by admin is:

'SELECT 
"user_profile_userprofile"."user_id","user_profile_userprofile"."portrait","user_profile_userprofile"."blog_setting_id"
FROM "user_profile_userprofile" ORDER BY "auth_user"."username" DESC'

There is exactly not auth_user and user_profile_userprofile table name
in from clause.

I don't know if it's a bug in Admin.

Any suggestion?

Using Site is the same as using any other external model module; once
you import it, you can refer to parts of it (e.g., through
ForeignKeys) just like parts defined in your local model module.  Site
isn't "special" in this respect.  :-)

Re: How to implement this fucntionality ? (current page higlighting)

[akaihola]

A simple solution is to indicate the current page (or section) in the
context. You can do it in your urls.py (see
http://www.djangoproject.com/documentation/url_dispatch/#passing-extra-options-to-view-functions
) or in views.py.

Let's say you have inserted {'section': 'ajouter'} in your context.
Then in your menu template you can do:

{% ifequal section "ajouter" %}
Ajouter une recette
{% else %}
Ajouter une recette
{% endifequal %}

thanks for the help.

at the end, i did the followin:

- no javascript-visibility tricks
- the form's submit buttons are written out using document.write
- i added a  tag to warn the user to enable javascript

this way, if javascript is disabled, the user cannot submit the form. he 
can still see it, but cannot submit (so cannot break anything).

Subclassing user and OneToOneField

[Kirk McDonald]

I have expanded auth.User (gosh that seems to be a popular thing to do) 
according to the instructions here:
 http://code.djangoproject.com/wiki/ExtendedUserModel
The particulars are more complicated to explain than the code itself:

class User(users.User):
 id = meta.OneToOneField(Node, db_column='id')
 class META:
 replaces_module = 'auth.users'
 module_name = 'users'

The first question you're probably asking (beyond "What the hell are you 
thinking?") is "What's Node?" The short answer is:

class Node(meta.Model):
 title = meta.CharField(maxlength=255, blank=False)
 nodetype = meta.CharField(maxlength=30)

 def __repr__(self):
 return self.title

I also have a Document model that is likewise very simple:

class Document(meta.Model):
 node = meta.OneToOneField(Node)
 content = meta.TextField()

Every Document is-a Node. Every User is-a Node. Assume I have various 
other kinds of things that are also Nodes. If I want the User to also 
have a Document tied to its Node (say, for a bio or whatnot), that is 
quite simple to arrange.

This is all fine and dandy, but changing the id field like this isn't 
doing precisely what I want: The normal, default, AutoField id field is 
named 'id', i.e.:

 >>> from django.models.node import nodes
 >>> n = nodes.get_object(pk=3)
 >>> n.id
3

But with my User model:

 >>> from django.models.auth import users
 >>> u = users.get_object(pk=3)
 >>> u.id
Traceback (most recent call last):
   File "", line 1, in ?
AttributeError: 'User' object has no attribute 'id'
 >>> u.id_id
3

Duh! The magic turns id into id_id. It's just what OneToOneField does. 
This difference in the interfaces of my User class and the standard one 
rears its ugly head when I try to log in to the admin:

[snip]
Exception Value:'User' object has no attribute 'id'
[snip]
/usr/lib/python2.4/site-packages/Django-0.91-py2.4.egg/django/contrib/admin/views/decorators.py
 
in _checklogin

   85. request.session[users.SESSION_KEY] = user.id
[snip]

Oh dear.

I have two options as I see it: I can either edit the admin code (not 
preferable for any number of reasons), or I can somehow convince an id 
attribute to spring into existance. Being relatively new to Django, I am 
not sure of the best way to do either of these.

-Kirk McDonald

PS: The following hackish thing occurs to me:

class User(users.User):
 node = meta.OneToOneField(Node, db_column='id')
 id = meta.IntegerField(db_column='id', editable=False)
 class META:
 replaces_module = 'auth.users'
 module_name = 'users'

Is this a completely terrible idea? I haven't tested it yet, though 
instinct tells me I'll almost certainly have to set the db table up 
myself...

Unfortunate side effect of the CSS method, however, is what happens when
the user isn't using a browser that supports CSS, say a text based
browser. You'll then get the form displayed, which probably isn't the
right way to go ;)

The javascript, although not the cleanest way, is probably best for the
case that you really do not want the form to be displayed.

Cheers,
Brett.

Data Flow for an App to Another

[iGL]

Hi,
As I suppose, the Django's concept of separation of application from
a project, when several apps form the latter, is a very nice
abstraction of the traditional MVC. It would enable one to re-use apps
in an extent exceeding what is provided with the "classic" MVC.

However, to do so, one has to organize the model of an app in such a
way that the app mustn't know anything (or, more precisely, as few as
needed) about its "neighbors".

That's my question: is there a documentation, or informal blog
postings, describing how different apps can share data via
django.core.Site? Browsing django.contrib source is a good way, but the
aforementioned (docs, blog postings) would also help.

Please, give me links to them, if they are available.
Thanks in advance,
Giorgi

filter object_list in generic views

[char]

I'd like to have a search form drive a generic list/detail view. Is
there a way to filter the db query that generates object_list based on
a search form? It doesn't seem like I should have to write a custom
view just to filter list results.

Thanks

Charlie
