Genuine cross-database queries are going to be a problem regardless --
Django doesn't handle foreign keys that cross database boundaries. However,
if it's just a matter of having three different data stores, that's not a
problem at all -- it just means you'll have multiple entries in your
database configuration.

There's a "yikes" factor here in terms of the number of tables you'll need
to configure, but inspected will help you out here, and once that's done,
you shouldn't have any problems in practice.

You can certainly override the save() method and make it a no-op; you don't
need to touch __init__ at all to do this. Just make a subclass of
django.db.models.Model that defines a no-op save() method, and make sure
all your "views" extend this base class. Simliarly, you can override the
model manager to provide a default query set that makes the update a no-op.
As a third line of defence, you can write a database router that directs
write queries to a no-op database, so if something does accidentally
trigger a database write, it won't allow the update to occur.

You can always override the .save() method to check to see if the pk field is 
None, and refuse to save if it is not:


https://docs.djangoproject.com/en/1.4/topics/db/models/#overriding-predefined-model-methods

That being said, this kind of thing is *much* better done at the DB level, so 
that you can be certain that there are no other paths that allow data to be 
updated.

You are directly importing a package which is on the Python path so the
system finds it ok. But, that package (django_tables2) apparently
expects to be imported by some other bit of code which already knows
where your settings.py file lives.

If you want to import it directly it needs to know where to look.

You might need a PYTHONPATH environment variable which specifies the
path to your Django project. If settings.py lives in
C:\webwork\djngony\project\xyz\settings.py. Then your PYTHONPATH needs
to include C:\webwork\djngony

The traceback indicates, you need a DJANGO_SETTINGS_MODULE environment
variable. In my example above it would simply be project.xyz


Correction ... project.xyz.settings

or xyz.settings if C:\webwork\djngony\project is in the PYTHONPATH

Append only tables/models

[Mike Burr]

I know there are DBMS-specific ways of doing this. I know that there
are Django ways of making fields read-only. What I cannot find is a
way to make a table/model append-only.

It'd be great if this were at the DB level, so I don't have to rely on
my code not having any holes that allow edits. I don't know of a RDBMS-
neutral way of doing this. I'm using sqlite for testing (which appears
to have no such feature).

Is there a clean, "Django way" of doing this? I'll put my trust in
Django to prevent subsequent updates if I have to.

Just to clarify: I want for (all) users to be able to insert rows, but
not make edits after the fact (like you might want to do with logs,
but that's not the use case.)

Thank you!

Re: Connecting to external databases from Views.py

[jirka . vejrazka]

Hi Gregg,

  I've done something similar in the past - had several external databases (MS 
SQL and Oracle) attached to my Django project. These were backends of 
enterprise tools, hundreds of tables each.

  I used the "manage.py inspectdb" command to reverse engineer each "external" 
DB, manually polished models I needed (inspectdb is great but can't always 
perfectly guess foreign key relations or field types). Then I set 
"managed=False" for each model of those external DB's to make sure Django won't 
try to modify them.

  As for writing to those DB's, I had set up my DB routing so that these DB's 
were available only for read, not for wrining. I made sure that my code never 
attempted to write to those DB's. I also never used Django admin for this 
project. 

 YMMV

   Jirka

P.S. You can override the save() of your models in"external DB"  method to do 
nothing

Hi Russel,

First off thank you for the suggestion, I am going to give it a whirl and 
see how it works out.. I have a couple of concerns about the pricing 
database it the
* it is on  mssql and the data is spread accross 3 database on the same

problem.
* the db's have like 300 table each..

Before you answer I wat thinking of accessing the database on the view 
*yuck* via pyodbc.

after your answer I have a couple more questions ?

Is is possible to override how a model is loaded from the database with raw 
sql and then overide the save and update methods to do nothing ? I have 
look at ovveriding __init__ but all recommendation are against it, but 
since I am not saving would it make any difference ?

Thanks very much for you previous answer as I feel it is pushing me towards 
a better solution

RE: Displaying a custom field (PickledObjectField) in the admin

[lacrymol...@gmail.com]

The short of it is that you should probably subclass the picklefield to add 
some new validation (basically is_integer_two_tuple_list), and write a custom 
widget for it that does what you want on the html side. The long of it needs 
not being written from a phone

Asunto:  Re: Displaying a custom field (PickledObjectField) in the admin

Hi Tomas & John,

Thank you for your reply.  Basically I'm trying to save curves which I 
chose to format as:
[[0,0],[1,0],[2,1],[3,1], ... ,[40,0]]

To see what I tried before (models, etc) you can see the stackoverflow 
questionI
 asked previously.
Some people there suggested the django-picklefield so I implemented it but 
couldn't get the admin to work.
Unfortunately I would eventually need users to put in numbers in a template.

For the moment I'm just saving a TextField and doing some pretty coarse and 
inelegant validation + assuming we enter the curves in the admin.

def save(self, *args, **kwargs):
pc = self.my_power_curve
if pc[0]!='[':
pc = 'error. no initial [ --- ' + pc
self.my_power_curve = pc
elif pc[-1] != ']':
pc = 'error. no final ] --- ' + pc
self.my_power_curve = pc
elif  pc.count('[') != 42 or pc.count(']') !=42:
pc = 'error. 41 pairs [,] are required or too many brackets --- 
' + pc
self.my_power_curve = pc
elif  len(pc)>362:
pc = 'error. too many items --- ' + pc
self.my_power_curve = pc
elif pc.count('(') != 0 or pc.count(')') != 0:
pc = 'error. only "[" and "]" brackets allowed --- ' + pc
self.my_power_curve = pc
else:
pass
return super(SomeClass, self).save(*args, **kwargs)


Ideally I would create form with say 41 little fields:
value 1 = [  ]
value 2 = [  ]
value 3 = [  ]
...
value 41 = [  ]

and when the users completes *some of them*, I save it as a string:
"[[0,0],[1,1],[2,3],[10,20],[20,20],[40,0]]"

Eventually I want to retrieve them and calculate things (like area under 
the curve or make a graph).

Any ideas are appreciated,

Thank you,
Alvaro

Re: "calculated" filed in model

[Russell Keith-Magee]

Hi Mike,

Easily done, and no need to use signals or raw SQL: just override the save
method on your model so that every time you call save, the value in the baz
column is updated.

class Foo(models.Model):
bar = models.CharField()
baz = models.CharField()

def save(self, *args, **kwargs):
self.baz = function(self.bar)
return super(Foo, self).save(*args, **kwargs)

As a warning, there are some times when this won't work. For example, baz
won't be updated if you use a .update() call on a queryset, and it won't be
updated if you load a fixture or perform a "raw" save. However, this would
also be true of a signal based approach. For most simple uses, it should be
fine.

Yours,
Russ Magee %-)

"calculated" filed in model

[Mike Burr]

I would like to accomplish the following:

class Foo(models.Model):
bar = models.CharField()
baz = function(self.bar)

Of course this doesn't work (at least as I want it to), but I'm guessing 
that most humans will know what I'm trying to do. What I want is:

1) User supplies value for 'bar'
2) User clicks 'Save' 
3) baz column gets value returned by 'function' (which will be a large 
string)

I don't care if 'baz' shows up on the Admin form, so long as after saving 
the calculated value shows up. I could probably do this with a DB trigger, 
but I'd like to do it the Django way. A trigger would also not be 
RDBMS-neutral I considered using signals, but:

1) I don't think I can use pre_save, since I don't have a row yet.
2) I don't think I can use post_save because I don't know of a way to 
identify the right row. Also, post_save would make the transaction 
non-atomic (right?) If "function" threw an exception for example, the row 
would still get saved.

If I do use a signal, I'd also like to avoid using raw SQL if possible. I'd 
have to hard-code table, column names, which seems ugly to me. I just know 
there's a quick, elegant way of doing this. I'm just not Django savvy 
enough yet.

Thank you!

Re: Python-requests seems to 404 with Django/Tasty-pie?

[Alex]

I just discovered that the requests library honors HTTP_PROXY, but does not 
honor NO_PROXY. 

Based on what you say below, I'm betting this is your problem, or at least 
a part of it.

One solution is for you to explicitly unset HTTP_PROXY when you don't want 
it.

Another is for you to specify a proxies dict for requests.

Good luck!

Best
Alex

Re: Connecting to external databases from Views.py

[Russell Keith-Magee]

Hi Gregg,

Is there any reason you can't treat this as a mutliple-database
configuration?

https://docs.djangoproject.com/en/dev/topics/db/multi-db/

Django allows you to specify more than one database, and then direct
queries at specific databases. So, you have your "main" django database for
your own application, but you set up a connection to your "other" database
to access the pricing report.

You'll need to write some Django model wrappers for the data in the 'other'
database -- inspectdb can help with that -- but once you've done that,
you'll be able to query the 'other' database as if it were a set of normal
Django models.

Yours,
Russ Magee %-)

RE: Best way to detect if a user has changed password

[lacrymol...@gmail.com]

If you hook into pre_save, you can compare agaist the DB with 
MyModel.objects.get(id=object.id)

I think there might be a way of checking directly on the instance if a field's 
been changed in 1.4

Asunto:  Best way to detect if a user has changed password

I'm running a Django 1.4 site and I have some operations I want to perform 
if a user changes their password.  I'm using the standard contrib.auth user 
accounts with the normal password_change view and I'm not sure if I should 
somehow hook into this view or if I should use a signal on post_save for 
the user.  If I do use the signal, is it possible to tell when the password 
has been changed?  I do feel that if I can use a signal this might be the 
best approach since it would handle any other password change mechanisms 
that I might add later without any extra work.

Does anyone have any ideas on the best way to do this?

Re: Displaying a custom field (PickledObjectField) in the admin

[Alphydan]

Hi Tomas & John,

Thank you for your reply.  Basically I'm trying to save curves which I 
chose to format as:
[[0,0],[1,0],[2,1],[3,1], ... ,[40,0]]

To see what I tried before (models, etc) you can see the stackoverflow 
questionI
 asked previously.
Some people there suggested the django-picklefield so I implemented it but 
couldn't get the admin to work.
Unfortunately I would eventually need users to put in numbers in a template.

For the moment I'm just saving a TextField and doing some pretty coarse and 
inelegant validation + assuming we enter the curves in the admin.

def save(self, *args, **kwargs):
pc = self.my_power_curve
if pc[0]!='[':
pc = 'error. no initial [ --- ' + pc
self.my_power_curve = pc
elif pc[-1] != ']':
pc = 'error. no final ] --- ' + pc
self.my_power_curve = pc
elif  pc.count('[') != 42 or pc.count(']') !=42:
pc = 'error. 41 pairs [,] are required or too many brackets --- 
' + pc
self.my_power_curve = pc
elif  len(pc)>362:
pc = 'error. too many items --- ' + pc
self.my_power_curve = pc
elif pc.count('(') != 0 or pc.count(')') != 0:
pc = 'error. only "[" and "]" brackets allowed --- ' + pc
self.my_power_curve = pc
else:
pass
return super(SomeClass, self).save(*args, **kwargs)


Ideally I would create form with say 41 little fields:
value 1 = [  ]
value 2 = [  ]
value 3 = [  ]
...
value 41 = [  ]

and when the users completes *some of them*, I save it as a string:
"[[0,0],[1,1],[2,3],[10,20],[20,20],[40,0]]"

Eventually I want to retrieve them and calculate things (like area under 
the curve or make a graph).

Any ideas are appreciated,

Thank you,
Alvaro

Re: Puzzled about WSGI vs. FastCGI

[Nikolas Stevenson-Molnar]

Correct. I've found proxying to an HTTP WSGI server to be eaisier as you
don't need to configure passing of FastCGI params. I use Gunicorn with
nginx, and it requires very little all around configuration. I would
expect Gunicorn with lighttpd to be similar.

a way to display a model formset in a ModelAdmin ?

[Nicolas Emiliani]

Hi,

As the subject states, is there a way to display a model formset in a
ModelForm?

The thing is that I have a Verification model with its ModelAdmin, and then
I have
an ImageModel that has no ForeignKey to the Verification model (and I
intend to keep
it that way) so I can not inline it into the VerificationAdmin and I would
like to show
a list of Images in my VerificationAdmin based on a queryset performed (i
assume) at
__init__ method of VerificationAdminForm. How could this be accomplished?

This is how it goes:

class Image(models.Model):
   

class Verification(models.Model):
   

class VerificationAdminForm(forms.ModelForm):
   

class VerificationAdmin(admin.ModelAdmin):
   form = VerificationAdminForm
   model = Verification
   fieldsets = [ ... ]

Any ideas would be greatly appreciated.

Thanks in advance.

Re: Puzzled about WSGI vs. FastCGI

[Fred]

Thanks guys for the infos. It makes a lot more sense now.

So it looks like Lighttpd does not support the equivalent of mod_wsgi, so 
requires a second server that speaks either FastCGI or HTTP/WSGI.

Re: Best way to detect if a user has changed password

[Brad Pitcher]

You could use a "pre_save" signal. kwargs['instance'] will contain the
updated record and you can get the old record with "User.objects.get(id=
user.id) if user.pk else None". I've done this in the past to check for a
changed email address.

Why does BaseHandler::handle_uncaught_exception() not always log?

[Roy Smith]

In core/handlers/base.py, handle_uncaught_exception() does:

if settings.DEBUG:
from django.views import debug
return debug.technical_500_response(request, *exc_info)

logger.error('Internal Server Error: %s' % request.path,
exc_info=exc_info,
extra={
'status_code': 500,
'request':request
}
)

Wouldn't it make more sense to always log the exception?  As it stands now, 
it's an either/or deal.  If DEBUG, produce the debug page and don't log. 
 If not DEBUG, log and produce a normal 500 page.

I ended up writing my own process_exception() middleware to log stack 
traces for all uncaught exceptions.  This was fine in development, but in 
production, with DEBUG = False, I get *two* stacks in my log files for 
every exception (one from my hander, another from the code above).  This 
all seems silly.  It would be so much simpler (and obvious) if 
handle_uncaught_exception() always logged, regardless of which flavor of 
response it's going to produce.

Best way to detect if a user has changed password

[Roarster]

I'm running a Django 1.4 site and I have some operations I want to perform 
if a user changes their password.  I'm using the standard contrib.auth user 
accounts with the normal password_change view and I'm not sure if I should 
somehow hook into this view or if I should use a signal on post_save for 
the user.  If I do use the signal, is it possible to tell when the password 
has been changed?  I do feel that if I can use a signal this might be the 
best approach since it would handle any other password change mechanisms 
that I might add later without any extra work.

Does anyone have any ideas on the best way to do this?

Connecting to external databases from Views.py

[Gregg Branquinho]

Hi guys I am new to django and have built my first application that is 
being used to track and compare pricelists from vendors and it is working 
awesomly, I have had a request for a new feature and I am alittle boggled 
at to how I am going to do it..

Basically I wasnt to create a view which returns read only data(a report) 
from an external database which is not the django database. I dont want to 
copy the data to the django database and use a models as then concurreny 
become an issue

What would you guys recommened..

I was thinking on implenting a odbc connection from the views.py method 
called for my url ? but database call from the view , sound a abit dodgy.

Any ideas ?

django ajax Post returns empty message

[psychok7]

using django 1.4, I can Post but the Post response comes (undefined) empty 
but GET works fine. i am using the csrf checks not sure if the problem also 
comes from there

my django view:

@csrf_protect
def edit_city(request,username):
conditions = dict()

#if request.is_ajax():

conditions = request.method
#based on http://stackoverflow.com/a/3634778/977622

here is my javascript code :

if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 
1));
break;
}
}
}
return cookieValue;
}
var csrftoken = getCookie('csrftoken');

function csrfSafeMethod(method) {
// these HTTP methods do not require CSRF protection

}

}
$.ajaxSetup({

}
});

$.post(url,{ type : type , city: cityStr, pois: poisStr, poisdelete:

not exactly like that.  it's not about which is higher-level, or which
runs on top of what... i see it more like a chain of protocol
conversions.

at one end, it's WSGI, it's a standard, a convention of how to call
Python functions to implement web applications.  Django is implemented
as a WSGI application, so you need something that makes those WSGI
calls.

at the other end is the user browser, which does HTTP requests.

so, you need to translate HTTP requests to WSGI calls, and the
returned WSGI responses into HTTP responses.

there are HTTP-WSGI servers, like gunicorn, and tornado, and lots others.

there are also many HTTP servers that can use a multitude of back-end
protocols to talk to webapps.

Apache, for instance can do FastCGI.  if so, you can use flup to serve
FastCGI with WSGI calls.

or you could use mod_wsgi to skip flup and keep the HTTP-WSGI within
Apache.  (this is the recommended structure for Apache)

several other webservers can do FastCGI, like lighttp or nginx.  in
all those cases you can still use flup.

but nginx is also a quite good HTTP-HTTP load-balancer, so you can use
gunicorn to serve HTTP behind nginx.  this is a very popular setup.
or you can replace nginx with lighttp in proxy mode.

another very good alternative is uWSGI, which adapts several protocols
and calls WSGI apps (and others!).  It was originally designed to use
a very compact and efficient protocol, mainly driven by a mod_uwsgi
add-in for nginx.  this can be a very low-overhead, high-performance
option.  uWSGI also has many, many options to administer the whole
system with great detail.

hope that helps.

Re: Displaying a custom field (PickledObjectField) in the admin

virtualenvwrapper dies while mkproject & mkvirtualenv

[Ashkan Roshanayi]

Hi I've installed pip using easy_install on my mac and later installed 
virtualenv and virtualenvwrapper both successfully.  

wrapper doesn't work at all and when I invoke it by mkproject or mkvirtualenv 
it go on till this line:

> Setting project for test to $PROJECT_HOME/test
> 



and from here it takes a long time with no output or progress. Any idea on how 
can I fix this?

Date widget not HTML5

[Juan Pablo Tamayo]

Is there any reason not to have the date widget input tag have the 
attribute type="date" instead of just type="text"?

I mean, most browser do not treat it differently, but it tells them that 
they should; besides it would mean that Django tries to support the full 
range of HTML5.


Is there a way to change this particular behavior?

Thanks in advance fellow Django-mates!!!

Internationalization: trans with object property

[Ma Ba]

Hi,
I have a question about the internationalization feature ...

I have a country model:

class Country(models.Model):
nameKey = models.CharField(max_length=50)
shortNameKey = models.CharField(max_length=30)

The properties 'nameKey' and 'shortNameKey' contain resource keys like 
'_country_af' or '_country_af_short'. I need this to show the country names 
depending on the current locale.

The problem was/is to add the resource keys to the .po file, so I found a 
solution in a forum: 
http://stackoverflow.com/questions/7625991/how-to-properly-add-entries-for-computed-values-to-the-django-internationalizati

For example, I added the following to a model file:

def dummy_for_makemessages():
#countries
pgettext('forecast type', '_country_af')
pgettext('forecast type', '_country_af_short')

Runing makemessages this generates the following entries in the .po file:

msgctxt "forecast type"
msgid "_country_af"
msgstr "Afghanistan"

msgctxt "forecast type"
msgid "_country_af_short"
msgstr "Afghanistan"

For testing purposes I tried to iterate over all countries in my database 
in a template and to print out the translated names:

{% for country in countries %}
{% trans country.nameKey %}
{% endfor %}

Unfortunately, it only prints out the following (the resource keys instead 
of the translated names):

_country_af 
_country_ai 
_country_qa 
_country_ke 
_country_kg 
_country_ki 
_country_cc 
_country_co 
...

I found out that the 'msgctxt' part in the .po file causes the missing 
translation. I removed it for testing purposes and this time it worked fine.

So, my question is, how can I translate resource keys that are not defined 
in the template itself but in an object property instead? Is there a way to 
generate the resource keys without the 'msgctxt' part? I tried NONE or an 
empty string but this generates a commented out resource key in the .po 
file (please see the link to the other forum above).
Does anybody have an idea how to solve this problem?

Thanks for your help in advance!!

Re: [Q: Basic] Strange behaviour after pressing on button

It's possible that the CSRF token isn't being sent correctly. As a test,
try adding the @csrf_exempt decorator to your view. If you no longer get
the 403, then it's a CSRF problem.

Re: Puzzled about WSGI vs. FastCGI

[Nikolas Stevenson-Molnar]

The easiest way would probably be to run Gunicorn (http://gunicorn.org/)
or some other WSGI HTTP server, and then configure lighttpd as a proxy,
e.g: https://gist.github.com/514252

Puzzled about WSGI vs. FastCGI

[Fred]

Hello

I'm trying to find how to install Python on a Lighttpd server that 
currently runs PHP scripts.

This 
articlesays:

> Although WSGI is the preferred deployment platform for Django, many people 
> use shared hosting, on which protocols such as FastCGI, SCGI or AJP are the 
> only viable options.


I'm puzzled, because I seemed to understand that WSGI is an API that relies 
on a lower-level transport solution like FastCGI, SCGI, or AJP.

Could it be that the article actually opposed mod_wsgi, which can run 
within Apache à la mod_php *?

And if someone knows of a good way to run Python through FastCGI (with or 
without WSGI) on Lighttpd, I'm interested: "Python FastCGI on lighty with 
flup" at the very 
bottomonly
 seems to run a specific script.

Thank you.

* altough it can also run in its own process, just like FastCGI

the django book is somewhat outdated, and long.

do that tutorial, it's quite short, you can get through it in a couple of hours.

you're saying next to nothing, but I *guess* you could do something like

return render_to_response("sql.html", { 'row': row })

at the bottom of your sql view, and write an sql.html template that
shows it the way you want...

Also, you'll better go on and learn that pyodbc library and how to
pass parameters into your queries, which will protect you against SQL
injection attacks.. and you should probably learn SOME python if
you're going to be coding in it.

And you shuold *really* at least run through the django tutorial at
least once, in order to get a grip on some of the basic django
concepts, like forms and models, which will help you a lot

[Q: Basic] Strange behaviour after pressing on button

[Stone]

My Django application is running on real server (apache2-2.2.22).
In urls.py is mentioned:
(r'^configSave/$', configSave),

My HTML is bellow. After pressing on configSave I am receiving HTTP
403 error page.

In view.py is mentioned:
def configSave(request):
configFile={}
if os.path.isfile(SSO_CONF) != False:
f = open(SSO_CONF,"r")
for line in f:
line = line.strip()
if re.search('^#',line) != None:
'''print 'This is the commentary'''
else:
'''print line'''
try:
name, value = line.split('=',2)
configFile[name]=value
print '<%s>%s' % (name, value, 
name)
except ValueError, err:
''' print 'This is empty row'''
configFile['SlaveDeactAppl']=configFile['SlaveDeactAppl'].split(',');

configFile['SlaveDeactScripts']=configFile['SlaveDeactScripts'].split(',');
configFile={}
if os.path.isfile(SSO_CONF) != False:
f = open(SSO_CONF,"r")
for line in f:
line = line.strip()
if re.search('^#',line) != None:
'''print 'This is the commentary'''
else:
'''print line'''
try:
name, value = line.split('=',2)
configFile[name]=value
print '<%s>%s' % (name, value, 
name)
except ValueError, err:
''' print 'This is empty row'''
configFile['SlaveDeactAppl']=configFile['SlaveDeactAppl'].split(',');

configFile['SlaveDeactScripts']=configFile['SlaveDeactScripts'].split(',');
c = {}
c = Context({
'config':configFile,
'item':2,
})
c.update(csrf(request))
return
render_to_response('config.html',c,context_instance=RequestContext(request))

By the way how to really fast define logging mechanism which can be
use for debugging.

Is this my programmer approach corrector is there any other way how to
react on the pressing of button?

Re: Send data back to a table from template or send back to a view

Hi,

like Stephen mentioned you can use a post request [1] for that.

The field 'data' could contain the list of coordinates in an array [2] 
with the name 'coords' which itself can be accessed within the view via 
request.POST['coords'].


One of many examples you can find here: 
http://stackoverflow.com/questions/5457568/retrieving-post-data-from-jquery-in-django-without-a-form


[1] http://api.jquery.com/jQuery.post/
[2] http://de.selfhtml.org/javascript/objekte/array.htm

Good luck,

TR



thanks

Re: [ver. 1.5] Specifying custom User model (extends AbstractUser) doesn't work

If you're going to give advice, it's probably a good idea to check that
your advice is current.

The approach that the original poster has suggested is in no way "breaking
the architecture" of Django - it's one of the new features in Django 1.5.

As a side effect of the changes introduced in 1.5, the API you've suggested
(AUTH_PROFILE_MODULE) has been deprecated. It will raise warnings if used
in Django 1.5 and 1.6, and be removed completely in Django 1.7.

Yours,
Russ Magee %-)

Hi,

You can extend Default Django User model without breaking its architecture.
Just visit http://www.f2finterview.com/web/Django/21/ It will explain you
in detail.
