Interrelated form fields

[Julián C . Pérez]

Hi all
I have a question to make
I'm tryng to build a form using the following models:

---
in models.py

class Client(models.Model):
   user = models.ForeignKey(User, verbose_name=u'associated user')
   telephone = models.CharField(u'Telephone number', max_length=33,
blank=False, null=False)

class Appointment(models.Model):
   client= models.ForeignKey(Client, verbose_name=u'associated
client')
   date = models.DateField('Booked to', blank=False, null=False)

---

As you see, the Appointment model depends on the Client one
So, I want a form showing at first the client's select box according
to the DB records of model Client
As soon as one client is selected, I want the form to show only the
appointments booked to him

How can I make that happen?
Thanks!

Re: template tag question

Hi
I use Django 1.0 and I define a template function like...

def doSomething(param1, param2):
   # Do something like...
   return str(param1)+''+str(param2)
register.simple_tag(doSomething)
---
to use that in template system, assuming a and b are in context...
---
{% doSomething a b %}

Re: Get current user outside a view / without an request object

[Julián C . Pérez]

My real problem it that the field should looks like:
---
recipientUser = ShowValidContactList(currentUser=_something_,
label=u'Send to')
---
and if I have a form's init method like...
---
def __init__(self, *args, **kwargs):
self.currentUser = kwargs.pop('currentUser', None)
super(SendMessageForm, self).__init__(*args, **kwargs)
---
it won't change the current user already defined in the field

Now, I want to make something like...
---
recipientUser = ShowValidContactList(currentUser=getCurrentUser,
label=u'Send to')
---
where 'getCurrentUser' is a callable function similar to:
---
def get_image_path(instance, filename):
return 'photos/%s/%s' % (instance.id, filename)

class Photo(models.Model):
image = models.ImageField(upload_to=get_image_path)
---
how can I do that?

that init method in my custom form class won't change anything in the
already defined ShowValidContactList field

I also tried threadlocal's approach... but it didn't work either and
it's a weird way to do that...
I'm gonna go in a different direction, inspired by similar former
problem
Thank you alll, now I'll report with my status

Get current user outside a view / without an request object

[Julián C . Pérez]

Hi everyone
I'm in trouble because of a form class
I have a form class with attributes defined, but with one thing:
One of the attributes requires the current user, or al least its
username

The form definition in as shown below:
---
class SendMessageForm(forms.Form):
recipientUser = ShowValidContactList(label=u'Send to')
messageSubject= forms.CharField(label=u'Subject')
messageContent = forms.CharField(label=u'Content',
widget=forms.Textarea())
---

As you can tell I'm trying to make a 'Send message' form to make
message sending available in my project... but the recipient user must
be in the contacts list of the current user...
The 'recipientUser' field is a ShowValidContactList
(forms.ModelChoiceField) instance... so it works with a fixed queryset
based on that user (the currently logged-in one)

My problem is that... how can I get the current user information
outside a view and without request objects??
Or... how can I make that form works with a different approach??


Any help would be appreciate!

Managing settings.py from admin site

[Julián C . Pérez]

Hi everyone
I have a doubt...
Is it possible to edit or customize -not delete- variables created in
settings.py from the admin site of my application??
I mean, in order to control the whole site from web interface instead
of manually editing settings.py
I hope I made myself clear...
Any idea??
Thanks!

Re: ModelForm customizing

thank you,s ean
i will try
ahh one thing i'd like to comment...
when creating an ProfileForm object I even give it the class as an
argument like this:
...
profile, created = Profile.objects.get_or_create(user=request.user)
myProfileForm = ProfileForm(request.POST, instance=profile,
error_class=DivErrorList)
...
but nothing happens... that object still uses the default error class

another question on my mind...
how can i assing to that form a custom class??
i mean, to create something like:
...

...
i'd like to achieve that in order to control those fields using jquery
-for validation reasons

thank you all!

ModelForm customizing

[Julián C . Pérez]

hi everyone
me again...
i need some help
i want to change the error_class in a modlefrom instance
the class looks like this:

# in a models.py file
1 .class ProfileForm(forms.ModelForm):
2.
3.  error_class = DivErrorList
4.
5.  class Meta:
6.  model = P
7.  exclude = ('date', 'user', 'public')

obviosly, the 3rd line doesn't do anything
i know that ProfileForm inherits from ModelFrom, which is a instance
of BaseModelForm (the class that has the 'error_class' attribute)
how can i change that attribute within my instance of ModelForm??
if i have to override the __init__... how can i do that to make all
things work??
thanks!

Re: Template tags and variables overlapping

[Julián C . Pérez]

okss
thank u all for your replies
i have a new question about it...

in order to make more portable my code, i like to create warepper
functions to anything...
i want to make a function -in this case a template tag- for creation
of links...

example:
{% createLink "a link to something" src "class attr" "id attr" "title
attri" %}
would output something like:
a
link to something

how can i make the 'src' input to be the result of url tag calling a
valid view??
i mean, something like:
{% createLink "a link to something" "{% url aValidView %}" "class
attr" "id attr" "title attri" %} # obviously that is wrong... just to
make my point
a link to something

any help would be appreciated
;)

Template tags and variables overlapping

[Julián C . Pérez]

hi u all... again
this has become my first resource on getting help
a new doubt i have...
in templates...
i have a variable, let's say varOne -suposse it's equal to "Kathleen"
... {{ currentName }} ...
and i have created a custom tag which takes an argument, called
sayHello
... {% sayHello "Robert and Mary" %} ... > this would output 'Hello
Robert and Mary'
but if i do something like:
... {% sayHello "Robert and {{ currentName }}" %} ... > this would
output 'Hello Robert and {{ currentName }}'
needless to say i want some output like 'Hello Robert and Kathleen'

how can i get this to work??
thank u all!

Re: url template tag help

[Julián C . Pérez]

uhhh
i tried but nooo... your suggestion doesn't work...
let me show you 2 versions of error...

1. "Reverse for 'proyName.view_aboutPage' with arguments '()' and
keyword arguments '{}' not found."
settings:
# in proyName.packages.appName.urls.py:
 ... url(r'^about/$', 'view_aboutPage',
name='proyName.link_aboutPage'), ...
# in the template (about.html):
... show 'about' ...

2. "Reverse for '' with
arguments '()' and keyword arguments '{}' not found."
settings:
# in proyName.packages.appName.urls.py:
 ... url(r'^about/$', 'view_aboutPage', name='link_aboutPage'), ... #
also fails with "name='proyName.link_aboutPage'"
# in the template (about.html):
... show
'about' ...

by the way, the view loks like:
# in proyName.packages.appName.views.py:
...
def view_aboutPage(request):
return render_to_response('pages/about.html',
context_instance=RequestContext(request))
...

what can i do?? honestly, i do not know...
thanks!

FileField uploading into an user-specific path

[Julián C . Pérez]

hi u all
i'm progressing in my django wisdom jeje
but everyday i face new challenges and/or problems...
'im working on a uploading files application...
and i want to store every uploaded file into its right path, arranged
by username

example...
if a user called 'user123' uploads a file from a regular filefield in
a form... lets say: text.pdf
i want that pdf to be stored into 'path/to/uploads/user123/text.pdf'
right now i have 'path/to/uploads/text.pdf'

the model around the files is something like:
class Upload (models.Model):
  userUploader = models.ForeignKey(User)
  date = models.DateTimeField(default=datetime.datetime.now)
  fileUpload = models.FileField(upload_to=PATH)

how can i link the current user logged in to its specific path??
i mean, how can i make something like:
fileUpload = models.FileField(upload_to=PATH + "/" + User.username)
??

i hope i got myself clear...
bye!

More than one DB configuration in settings.py

[Julián C . Pérez]

Hi everyone
I need some help here
I'm in a rush, so I don't took first the time to explore the board and
solve this doubt...
How can I make two different DB configurations on the settings.py??
I mean... I manage my project through svn, but i make changes all over
it on two enviroments... Yes, you can figure it out: one Linux-based
and a Windows-based. So the DB host and name are not the same...
How can I do that??
- I imagine something like... DATABASE_HOST = { '127.0.0.1',
'172.3.25.200' } > the Windows host, then the Linux host
Thank you all

A distributed DB

Hi again
Another questions circling my head...
Anyone know any distributed DB system to engaged with Django/python??
I'm developing an storage application (uploading files into an
account) and it'd be useful
What about something like Cassandra, or Project Voldemort?? -
opensource alternatives to Amazon's Dynamo
Suggestions??

Re: a little help on creating a 'global' file

[Julián C . Pérez]

ok briel, maybe i should explain myself better
you're right about the function with that innecesary 'request'
object... but i'd need it for any other function -yet to be
implemented
-by the way, i use the shortcut render_to_response

regarding the html stuff, with the function defined early if i make
the call as:
- in a html template...

...
{{ ocultarEstado }}
..

i get: 
(aceptar)
instead of a link: (aceptar)

regarding the part of importing the functions...
what i want is to import all the functions within that
'globalValues.py'
actually i have only the import for the ocultarEstado method, done in
the settings.py file with:
...
TEMPLATE_CONTEXT_PROCESSORS = ( ...
'myproject.globalValues.ocultarEstado', ... )
...
i mean, i don't want to import each new method like:
...
TEMPLATE_CONTEXT_PROCESSORS = ( ...
'myproject.globalValues.function1',
'myproject.globalValues.function2',
'myproject.globalValues.function3', ... )

a little help on creating a 'global' file

[Julián C . Pérez]

hi everyone from colimbia
i'm new on django... so far, i love it... i'm very used to php, but
the solution with django/python is just awesome
i have started a project and i've been catching up with the basics...
right now i have 2 doubts...

1. i created a file called 'globalValues.py' in the root folder of my
project... the purpose?? to put in there all python functions created
by me and called frequently among the code, and also to put some html
'shortcuts' to common stuff...
the code in that file so far is next:
# --
# start code globalValues.py
def ocultarEstado(request):
return { 'ocultarEstado' : 'hi u user!' }
# end code
# --
very short right now jeje
my question about it: how can i make 'ocultarEstado' function to
output the string as html, instead of its raw representation??

2. said all above, in my 'settings.py' file there is the import as it
follows:
# --
TEMPLATE_CONTEXT_PROCESSORS = (
'django.core.context_processors.auth',
'django.core.context_processors.debug',
'django.core.context_processors.i18n',
'django.core.context_processors.media',
'myproject.globalValues.ocultarEstado',
)
# --
my question here: how can i import all functions inside 'globalValues'
file with one call?? -i'm looking for a "myproject.globalValues.*"
kind of expression"- making every function calling with an entry is
quite large...

thank u all!

Re: serving multiple hosts from a single django instance ?

[julián]

One more alternative:
you can capture the hostname with mod_rewrite and pass it to your views
using mod_proxy:

RewriteCond %{HTTP_HOST} ^site-one\.example\.com  [NC]
RewriteRule ^/(.*)$  /hostname/aware/view/%1/$1  [L,QSA,P]

(I've wrote from memory, it's not tested)

Then it's your view code responsability to filter content using the
hostname received that you should capture with your url configuration.

This is useful if you need to ellaborate on the mod_rewrite part before
reaching your python code.

I don't know about godaddy deluxe but it seems you should do everything
using CGIs.

Copy the django source somewhere in your home. Write a CGI to run the
setup.py, like

#!/bin/sh
echo Content-type: text/html
echo
cd /path/to/django/source
/path/to/python setup.py install --prefix=/path/to/your/home/python
2>&1

The same to sync the db, etc...

Hope this helps (a little)

Re: Django hosting

[julián]

Send me a private (to avoid being off-topic) e-mail with the type of
project (mainly how many users will test it, if you required disk for
file uploads and this kind of things)

If the client buy I cant host the final version for a bargain price ;)

manytomany polimorphic

[julián]

I have a model similar to:

class ProductOne(models.Model):
   name = ...
   price = ...
   ...

class ProductTwo(models.Model):
   name = ...
   category = ...

Whatever two different models.

I want to log activity on this many models with a class like

class LogEntry(models.Model):
   timestamp = Date...
   action = choice...
   product = ManyToMany(ProductOne OR ProductTwo)

How can I have a product field in LogEntry that can points to a
ProductOne object or to a ProductTwo?

thanks,   
J.R.

Quite interesting for me.
Solicited suggestion (or random thougth) follows.

I have something similar in my some-day-perhaps projects queue. I
thought rather to use a 2 steps approach.
First step is a django application that generates django applications
(it's better than a script to allow anybody to install and test it, and
you have a GUI for free).
Second step is part of the generated application: run a shell script
that create the environment, sync the database, load test data...

It will work like this:

 * The app will allow to upload one or more text files (CSV mainly)
 * File names inspire model names. Field names came from fist line
header.
 * Within a simple wizard UI you can choose the relationship between
models (just a bunch of select boxes with model and field names, KISS
philosophy)
 * Choose app name, and press "generate"
 * You get a tar.gz with python code, ready to un-gzip-tar anywhere,
run a shell script that setup the environment, create database, syncdb
and load test data
 * Test data will be loaded with python code like
MyClassOne(field1="aaa", field2="bbb",
field3=MyClassTwo(field1="ccc")).save()
 * The generated app run like any other, python manage.py runserver...

The app will store uploaded files with some other information (custom
templates, media files...) just to allow later modifications and app
regeneration.

I've take a glance at your script, it seems your approach is more
auto-contained but the target is the same, i.e. to generate easy apps
fast, isn'it?

Difficult to explain in a foreign language. Next time I'll try to
express myself in python.

Re: Django server

[julián]

Next time, under linux, you can use fuser:

# fuser -n tcp 8000
8000/tcp: 1234 567

where 1234 and 567 are the pid of the processes

Re: create models from the admin page?

[julián]

A web-based model editor is not an easy task. I think vi is the right
modeller tool (after a paper/pencil session)  or emacs if you're a
pianist.

For GUI-tools-aficionados I'd rather devote the effort to write code
generators for apps like umbrello
[http://uml.sourceforge.net/index.php]. A lot easier. A lot more
useful.
