Dajax isn't working

[Daniel França]

Hi all,
I just start to use Dajax with my Pinax based project
I followed the installation steps

and it's almost working :P

I tried to do a test just copying the following code from Dajax examplex:
http://www.dajaxproject.com/random/
I'ts calling the randomize function correctly (and I can debug it), but it's
not updating the field with the value.

I understood that there's no need to write any js code, right?

I just created my ajax.py and write this:

*import random
from dajax.core import Dajax
from dajaxice.core import dajaxice_functions

def randomize(request):
dajax = Dajax()
dajax.assign('#result','value',random.randint(1, 10))
return dajax.json()

dajaxice_functions.register(randomize)*


and added to my html code:






Just changed the "examples" name to my app name.

It's calling the function, I can debug it, but nothing change in my page.

What am I doing wrong?

use raw definitions like django docs says.
And why do u put ^ witch means beginning of the string in the middle?
That i think would be correct:

r'^articles/(?P\d+)/$'


I wasn't clear.  I was correcting the error message, given that the 
provided pastebin link didn't include any of the source, but only the 
404 text.


The error appears to be from two levels of urls.py.

The first something like:

(r'^blog/', include('application.urls')),

And the second, inside the application/urls.py file, is something like:

(r'^(?Pd+)', 'applications.views.view_function'),

This second one is wrong, I believe it should be:

(r'^(?P\d+)/', 'applications.views.view_function'),

I hope that is clearer,

Tim.

I get that sometimes too - I think it's just reloading the server as it 
has noticed a code change.  Refresh again in the browser and it's 
usually working again.


I find that if you're developing a template tag it's sometimes required 
to restart the server to pick up the new code.


What I tend to do is try not to restart, and if something isn't working 
I'll restart the test server as my first test.  If it still doesn't work 
then it's more than likely my fault rather than the server's...

Re: Problem with reversing url in test

This problem turned out to be related to specificity. Another url
pattern was overriding the pattern that I was testing.

Re: Django on Apache

[Derek]

Thanks for the quick response, guys.  I guess what confuses me is the
need to EVER restart the server to pick up changes (excluding db
syncs).  It's been stated in many places (including Tim's response)
that the test server will automatically pickup code changes, but on
several occasions I've made changes to a view, and got a "cannot load
page/no response" (from the browser, not a Django error).  Once I quit
the server (Control-C), start it up again and refresh the page, it
works fine.

Can someone briefly explain the difference between PHP apps -- which
run your code "as is" without need for refreshing the server -- and
Django?

Again, much appreciated.

If you're developing, you can use the built in test server and that will 
pick up changes without refreshing.


If you're deploying on apache using mod_wsgi, you can set that up to 
automatically pick up your changes when the code updates.


Details at:

Hope that helps,

Consider a website that has multiple blogs, all of which are deployed to 
the same database.


Consider that you want each blog to be a separate URL: www.blog1.com, 
www.blog2.com, but you only want one database for ease of backing up etc.


So, you have one codebase, one database, but multiple sites.

You can achieve this using SITE_ID.  www.blog1.com has a settings.py 
with SITE_ID = 1.  www.blog2.com has a settings.py file with SITE_ID = 
2.  In your database, there are two rows in the django_site database 
table, with serials 1 and 2.  The table that holds the blog entries has 
a foreign key to Site, and so identifies which site the blog post 
appears on.


At least that's how I used it...hope that helps clarify it a bit!

Tim.

Re: Django on Apache

[Steven Elliott Jr]

MAMP can be a bit of a pain I think sometimes to modify, though I haven't used 
it much in the past few years. You can use the Mac's built-in apache server 
though with mod_python. Check out

SITE_ID

[craphunter]

Hey,

I do have problem with SITE_ID. I don't really get this. What is it?

I am using the django registration from bitbucker. When I click on
register I get the following error-message:

You're using the Django "sites framework" without having set the
SITE_ID setting. Create a site in your database and set the SITE_ID
setting to fix this error.

Am I right that I do have to set an ID in my database?

For example
mysql > test.db table 1?

settings.py

SITE_ID = 1

Can somebody write me a little tutorial?

Thanks,

Craphunter

Re: The REAL superuser

[nyambaa]

Hello Aug dawg,
Your code seems fine. You said: " I even manually created a
superuser". What does it mean?, How did you create super user?, and
check your auth_user_user_permission table in the database. Does it
mapped your user and required permissions.

good luck!

Re: How do you set choices in your application?

[werefr0g]

 Hello,

I'm not legitimate to answer you but I'm adding other options that 
experienced people can comment.


I'd rather use a ForeignKey in that context but I don't have to think to 
much to performances in my apps. You can easily add status, handle i18n 
this way. I must confess that writing "data in hard" into the code 
itself makes me nervous too. This is a documented option so maybe some 
arguments we'll help to overcome this bias.


If performances are an issue, I think about caching and I'll go to your 
third solution with 
http://docs.djangoproject.com/en/dev/ref/models/querysets/#pickling-querysets 
with maybe some "caching" issues to deal with.


By the way, I'll add to Russel's comments that even if someone tries to 
answer you, this can be time consuming because this answer will be send 
to the community and it better be as correct as possible (both in 
social, formal and  technical domains) and that implies reviewing your 
answer. You can take also in consideration than for some people, english 
is not really flowing when their main mentor is exception.Exception.


Regards,

Le 25/09/2010 02:51, Yo-Yo Ma a écrit :

Let's say I have a model with a field called "status". I could set the
choices in three ways:

1)   status_choices = ((1, 'Completed'), (2, 'Unfinished'), (3,
'Cancelled'))


2)  status_choices = (('COM', 'Completed'), ('UNF', 'Unfinished'),
('CAN', 'Cancelled'))


Or, 3 ):

db_choices = Choice.objects.all()
status_choices = [[choice.pk, choice.description] for choice in
db_choices]

Is there any best practice? Note: Client's won't be able to define
these choices. They'll all be defined by me (or else DB would be the
answer of course).

My thoughts:

1) Risky (data is useless without python file), 2) Slower, and risky
because it might be difficult to change later, 3) a lot of work, and
slow (because of DB).

Sorry for the double post but this statement is far from accurate (to be

preparation in the views. This maybe pointless in most practical cases 
but developpers are inclined to behave weirdly (this is a lame

Re: Universal form

[werefr0g]

 Hello,

You're assuming that form are called only from views. Some Form methods 
are mostly used inside templates like as_p for example. Another 
assumption you made is that all url point to html ressources. Images, 
javascripts can have their url. Generation of pdf, csv and AJAX 
mechanics are other examples.


As far as I understand, you want to display a login form in all your 
html pages. My first thought is to place it in a template extended by 
all html pages (I think about Django documentation 'base.html' 
template). You can't call the form's as_p (or whatever you want) as the 
form is missing from your context and built-in template tags and filters 
do not provide directly (AFAIK) what you need for that purpose but you 
can write your own [1][2].


Your context already provides request.user; you can use it to display 
login form or logout link according this context.


I don't know if this is a correct way to handle the case: maybe I'll do 
it another way with experience. The purpose is to point that you don't 
necessaraly need to work on "every function" from your views.

Re: How to debug ORM filter stacking?

[Ian Lewis]

Are you sure you are saving the new QuerySet that gets created by the
filter? I'm guessing you are doing something like:

qs = MyModel.objects.filter(field1="somevalue")
if condition:
qs.filter("someothervalue")

What you need to do is save the value of the second filter() call.

qs = MyModel.objects.filter(field1="somevalue")
if condition:
qs = qs.filter("someothervalue")

filter() returns a new queryset object rather than modifying the
queryset in place.

I usually debug SQL problems by using the
http://github.com/robhudson/django-debug-toolbar or pdb. With pdb you
can put import pdb;pdb.set_trace() where you would like pdb to stop
and it will allow you to debug from there. Simply showing the results
of the queryset usually gives some clues as to what the problem is. In
pdb you can see what sql will get run by running

(Pdb) print queryset.query

pdb's commands are explained here:

http://docs.python.org/library/pdb.html#debugger-commands

Re: How to debug ORM filter stacking?

I am stacking filters on queryset. For some reason the second filter
in stack is not applying and it is not giving any error either. Any
way to debug what is going on?


python manage.py shell

Import ur model, and build ur queries live. ipython has neat autoompletion  
feature. You might be able to figure out why it is working like it is.
