Django Development Server and Chrome - autorefresh

[Hari Mahadevan]

Hi,

I created a chrome extension that along with a custom django app 
automatically refreshes a Chrome browser page whenever the Django 
development server detects file change and reloads itself.

I have been using this for a couple of months now and find it indispensable 
as I use VIM for Django development. Hope you will find it useful too.

You can find the source and instructions on how to set it up on my github 
page --  https://github.com/harikvpy/django-autorefresh.

Thanks
Hari

IntegrityError : AUTH_USER DJango 1.8

[Jose Paul]

Daer All,

I am trying to run DJango 1.8 test cases .

I am getting several IntegrityError  error  on AUTH_USER table .


SQL generated by test case

INSERT INTO "AUTH_USER" ("PASSWORD", "LAST_LOGIN", "IS_SUPERUSER", 
"USERNAME", "FIRST_NAME", "LAST_NAME", "EMAIL", "IS_STAFF", "IS_ACTIVE", 
"DATE_JOINED") VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)

Values it tries to insert 

(None, None, True, u'superuser', None, None, None, False, True, 
u'2015-09-17 12:31:09.562000')

Error 
ibm_db_dbi::IntegrityError: Statement Execute Failed: [IBM][CLI 
Driver][DB2/NT] SQL0407N  Assignment of a NULL value to a NOT NULL column 
"TBSPACEID=2, TABLEID=24, COLNO=1" is not allowed.  SQLSTATE=23502\r 
SQLCODE=-407

In the table only LAST_LOGIN is nullable field .
But the sql generated tries to insert none to other fields .DB2 throw error 
because of this .

I think there is some problem in the sql generated .
I am getting several same  errors on this table .

Can someone comment please .

Thanks
Jose

regarding SESSION_COOKIE_DOMAIN

[Bharat Perumalla]

Hi

I am trying to use single-sign-on with sub domains. I configured 
SESSION_COOKIE_DOMAIN in django settings as ".cvbn.com" for all websites. I 
configured Apache with below configuration

   Header set Access-Control-Allow-Origin *
Header set Access-Control-Allow-Credentials: "true"
Header set Access-Control-Allow-Headers "SOAPAction, Authorization, 
username, password, origin, X-Requested-With, Content-Type, XMLHttpRequest"
Header set Access-Control-Allow-Methods "POST, GET, PUT, DELETE, 
OPTIONS"

But still I could not get cookie sharing across sub domains. Can you share 
some light on this?

Thanks
Bharat

DJango 1.8 test case fails with IntegrityError error

[Jose Paul]

I am trying to run DJango 1.8 test cases with DB2

Several insert statement fails 

Here is the insert command generated by test case.

"USERNAME", "FIRST_NAME", "LAST_NAME", "EMAIL", "IS_STAFF", "IS_ACTIVE", 
"DATE_JOINED") VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)

Value : (None, None, True, u'superuser', None, None, None, False, True, 
u'2015-09-17 12:31:09.562000')

ibm_db_dbi::IntegrityError: Statement Execute Failed: [IBM][CLI

Hi Jose,

I looks like ibm_db_django doesn't support Django 1.6+ yet

Django was present in FSD in Costa Rica

[Luis Zárate]

Hello everyone.

The past week was the Free software day here in Costa Rica (Yes, It was a
week of FSD's because it was in different days in different cities), we had
5 different events for this day in different cities. As part of our effort
for introduce Django in this country I imparted two lectures in this
events, the title was "Django: El framework web para perfeccionistas con
poco tiempo" (my translation of Django:The web framework for perfectionists
with deadlines.).
I am really happy because this lectures had many expectations and I saw
many people interested in Django after those lecture.
I just want to share this information with you because I am documenting
what is happening here.

Re: Best way to trigger javascript function when returning a page from django view

[Martín Torre Castro]

I'm looking soon which cases don't return the form filled with data, but
I've just tested and we have one that validates, but doesn't return the
data fields filled.

Maybe we're doing something wrong. I'm investigating.

Re: Invalid HTTP_HOST, can someone explain why I am getting this?

[frocco]

I am still getting this invalid host from time to time.
Does this mean that someone is trying to hack my site?

www.g3suprimentos.com.br is not anything I own.

For now, I am just ignoring this.

Thanks

Re: Invalid HTTP_HOST, can someone explain why I am getting this?

[François Schiettecatte]

Not likely, all that is happening is that you are getting requests where the 
‘Host:’ HTTP header is not set or set to something other than what is accepted 
by your site. Most likely a buggy client. I get that all the time, I just 
ignore it.

Cheers

The best way to solve this for good and never get those errors again is
to fix it in your front-end webserver configuration, so that it ignores
requests for the wrong Host and doesn't even pass them on to Django in
the first place. If you're using nginx that means setting your
`server_name` directive correctly. If you're using Apache that means
using a name-based (non-default) VirtualHost. Any webserver should
provide some way to do this.

Re: DJango 1.8 test case fails with IntegrityError error

[Jose Paul]

Hi Simon,

I am working on this support .

But the test case generates sql with null values for non null fields.

We cannot change the model ,because this is part of python ,i believe.

The problem might be the schema generated for the table from the model .
I can see only one field as non null in DB2.

Is this different from other database?.

Thanks,
Jose
