Re: uwsgi install question

[Trevor Joynson]

If there's no apt-get, you're probably on an rpm-based distribution
such as CentOS. you can tell what distro you are on via "lsb_release
-a".

Your webhost should already have libxml2 installed as it's required by
nearly everything web dev, but the header files sound like they aren't
installed (the devel packages).

If you don't have root access, you have two options:

1) (Easiest) Find the matching devel package version for the binary
libxml already installed and extract it to a folder, link against the
header files contained within by specified the include path, most
./configure scripts have such an option, something ala
--with-libxml=/path/to/libxml2

2) (More work without more profit) Download libxml2 and compile it,
specify the include path in the same way as above but you'll also need
to put this path in your LD_LIBRARY_PATH env variable.

Good luck!

uwsgi install question

[ecs1749]

I know this a Django group but uwsgi is blocking my way to seeing the next 
step of my first Django project.  There doesn't seem to be a uwsgi group 
that I can see.  So, I hope you don't mind.

First step for the uwsgi install procedure:

apt-get install build-essential python-dev libxml2-dev

but there is no "apt-get" with the westhost share hosting and uwsgi fails to 
install without libxml2.  Anybody?

Thanks,

Re: Choosing a JS framework to go together with Django

[dotnetCarpenter]

@Kelly Nicholes In backbone.js everything is in JS, meaning that there 
could be no conflict between declarative code and Django handled templates. 
If I can expose my python models, through auto serialization (JSON) from 
Django, I can see a productivity win. But I'm a little afraid of the tight 
coupling in data models between back-end and front-end. My main concern is 
that I'll have to rewrite large parts of JS if/when the models change. Have 
you any experience ironing out these issues? Maybe it's not a problem but I 
lack experience with both frameworks.

I'll look more into backbone.js :)

Re: Choosing a JS framework to go together with Django

@Peith Yes, I can see the advantage of not having to spend time working out

Hi vicherot.

I'm interested to know how you made the distinction between your dhtml/

the same code base to generate the 2 versions. Can you elaborate on the 
Django specific parts of your implementation?

Re: Choosing a JS framework to go together with Django

[dotnetCarpenter]

Wow - a lot of answers. Great community!

First of all, just to clearify. My aim is to have smooth user experience 
while utilizing Django and replicate as little code as possible on the 
client and the server. Think, reuse of server code on the client.

I've looked at AngularJS and it has a rendering layer that doesn't work 
without JS. Hence, no google support since google still requires us to 
deliver HTML 
snapshot.
 
Which means it violate my first requirement. AngularJS doesn't seem to 
offer help in this 
regard.https://groups.google.com/forum/?fromgroups=#!topic/angular/yClOeqR5DGc

Almost all JS frameworks in the wild, violate simple SEO rules, so it's not 
confined to AngularJS at all.

jQuery doesn't dictate client-side rendering. but doesn't offer any 
structure at all. Albeit it's great to build your own structure on top of.

Thanks for the list of frameworks. I haven't look at Knockout yet but it 
seems to require JS to do it's data bindings.

Cheers, Jon.

I tried it and found it quite difficult to follow guideline of unit testing

only way I could drive implementation with tests was using more like an
integration testing approach: calling requests with data and asserting that
new user was registered and that form was valid/invalid etc, but this goes
against TDD as I understand it. So should I not worry about pure "unit
testing" approach and use django client http request to validate
RegistrationForm. Or I should write unit tests for RegistrationForm class?


TDD is not unit-testing


Here is a lovely diagram I found recently - probably by following a link 
someone posted here - which shows the TDD process with unit tests and 
acceptance tests.


IMO it covers pretty much everything in the universe ...

http://www.methodsandtools.com/archive/attready3.jpg



https://www.google.com/webhp?q=tdd%20is%20not%20unit%20testing


in short, it's like you've found: the tests you easily get with TDD
are more (but not exactly) like integration tests, because you test
features, not units.  The "test isolated units" mantra of unit-testing
requires different work.  There's nothing wrong in adding 'real'
unit-tests, but it's not required to do effective TDD.

I guess that since unittesting became so well known so long ago,
almost all test frameworks (including Python's and Django's) call
their base test class "UnitTest", but they're not; they're just tests.
  you make them feature tests, or integration tests, or unit tests, or
whatever kind of test.

now, about the pros/cons of unit-testing vs. other kinds of tests.
that's a whole debate that i'm not going to touch.

Re: Validating GB telephone numbers in Django forms.

[g1smd.1]

The GB number plan is quite complicated, with a variety of number lengths 
and formats.
Some of it is detailed here:
http://www.aa-asterisk.org.uk/index.php/Number_format

I already compiled all the RegEx patterns that are needed. Some are listed 
here:
http://www.aa-asterisk.org.uk/index.php/Regular_Expressions_for_Validating_and_Formatting_UK_Telephone_Numbers

I've already started the process of translating a fully working PHP routine 
(that I wrote from scratch) into python. There will be syntax errors in the 
python version as I don't understand all that much of the python language.

The python functionality so far  
https://github.com/django/django/pull/324/files
or
https://github.com/g1smd/django/blob/master/django/contrib/localflavor/gb/forms.py

The code using an array is probably not quite right, and I guess it would 
be better to return error messages instead of "false" in some places.

However, I'd guess that someone who knows what they were doing could get it 
working in an hour or two.

 The code for that can usually be found in the forms.py file located in 
 the various country folders here:
 https://github.com/django/**django/tree/master/django/**
 contrib/localflavor
  

 So far, there is nothing for GB numbers, here:
 https://github.com/django/**django/tree/master/django/**
 contrib/localflavor/gb

 I've written a bunch of RegEx patterns to get this functionality 
 started. The patterns are 100% fully tested. All that's needed is a few 
 lines of python logic to string them together. The details can be found at:
 https://github.com/django/**django/pull/316/files

 My python foo is almost zero. Anyone care to have a go at getting this 
 to work?

 RegEx 1 checks the user entered something that looks like a GB 
 telephone number:
 020  3000  
 02075  567  234
 0114  223  4567
 01145  345  567
 +44  1213  456  789
 00  44  (0)  1697  73555
 011  44  11  4890  2345
 and several other formats, without worrying if the format is correct 
 for this particular number (but read on). It allows for national or 
 international format, even for two common international dial prefixes. 
 What 
 is most important is that the user enters the right number of digits. 
 Don't 
 constrain the user to use a particular format for entry.
 "Be lenient in what you accept, be strict in what you send." (Postel's 
 Law)

 RegEx 2 extracts the NSN part of the number in $3, with "44" or NULL in 
 $2 (so you know if international or national format was used on input), 
 and 
 any extension in $4. Store $2 and $4 for later. Send

Re: Editable Tables

[Sait Maraşlıoğlu]

Thx for greata tutorial, Ive already seen mygrid :)
in my website I will use mainly grid, lots of them, so I was looking for a 
solution to create them automatically, like django do that in its admin 
page.
if I keep doing them manually all grid titles and column names, its almost 
impossible, its not OOP either. and most importantly, it will be impossible 
to maintain it.
Anyways, I will keep searching, if I bump into something, I will drop a 
line.

Re: bound field object - dynamic forms

[mjh]

yes it is being passed to the template as I can access the label, choices, 
help_text, required items of the boundfield object...

i.e., {{ issue.label }} {{ issue.choices }} {{ issue.help_text }}

I can get everything it seems apart from the form object !!!

{{ issue }} writes to the template: 


???

I have timing built into the app using Navigation Timing:

Re: Easy way to temporarily disable the need to login

[Kurtis Mullins]

Actually, I take that back. I did some quick reading and found this from
Selenium's FAQ (http://selenium-grid.seleniumhq.org/faq.html)

"
Selenium Grid is not designed for performance and load testing, but very
efficient web acceptance/functional testing. The main reason for this is
that conducting performance/load testing with real browser is a pretty bad
idea as it is hard/expensive to scale the load and the actual load is very
inconsistent.

For load/performance testing I would advise using tools like JMeter,
Grinder or httperf. What you can do though, is reuse your selenium tests to
record the use cases you will use for your load testing. If you really want
to conduct load testing with Selenium, check out Browser Mob.

To simulate 200 concurrent users for instance, you would need 200
concurrent browsers with a load testing framework based on Selenium Grid.
Even if you use Firefox on Linux (so the most efficient setup) you will
probably need at least 10 machines to generate that kind of load. Quite
insane when JMeter/Grinder/httperf can generate the same kind of load with
a single machine.

No problem! Alternatively, you may have some luck with Selenium ...
although I have no experience here and am not sure if it can be made to
record times or any other indication of performance.

Re: Easy way to temporarily disable the need to login

[Kurtis Mullins]

Sure,

To submit a cookie, check this out:
http://stackoverflow.com/questions/3334809/python-urllib2-how-to-send-cookie-with-urlopen-request

To harvest a CSRF Token from a page (for example, as part of a form),
here's one example solution I found:
http://stackoverflow.com/questions/3145178/get-contents-of-a-tags-using-python
--
of course you'd want to grab the appropriate HTML Element.

Here's an example of setting and getting cookies:
http://stackoverflow.com/questions/5606083/how-to-set-and-retrieve-cookie-in-http-header-in-python

Here's some docs on the how to make the CSRF System happy:
https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#how-it-works

Re: Easy way to temporarily disable the need to login

[Larry Martell]

I got Anthony's code to work by adding the appropriate imports:

from django.contrib.auth.models import User
from django.contrib.auth import get_backends
from django.contrib.auth import login

Thanks very much!!

I have no idea how that would be done (neither extracting the token
nor passing it via urllib). I'm googling this, but if you know and

Do you want to use FTP to serve or accept the files?

Re: Easy way to temporarily disable the need to login

[Larry Martell]

The code is what Anthony posted, and the traceback is simply:


Traceback:
File 
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/core/handlers/base.py"
in get_response
  89. response = middleware_method(request)
File "/usr/local/motor/motor/../motor/middleware.py" in process_request
  29. backend = get_backends()[0]

Exception Type: NameError at /report/CDSEM/RawFile/
Exception Value: global name 'get_backends' is not defined


And I was under the impression that his middleware code would
eliminate the need to disable all login_required decorators, etc.

Re: Problem with Django recaptcha

[Amyth Arora]

This is because the re-captcha API is not able to recognize the keys ? do
you have the re-Captcha settings set to automatic  by any chance ? if so
change it to manual and add the domains you'd want to work it on and you
should have it working...

Re: Choosing a JS framework to go together with Django

[Amyth Arora]

I am not sure what you are exactly trying to achieve. A more issue specific
topic would have been easy to understand though i can suggest you following
frameworks (in particular order):

1. KnockoutJS
2. BackboneJS
3. Cappucino
4. Ember.Js
5. Sammy.JS
6. Spine.JS
7. JavascriptMVC

 Hi all - not sure how to show the choicefield dropdown in my template?

 Am generating a dynamic form (note: for issue in issues in forms.py) and

 in the template I am looping over these fields ({% for issue in 
 form.issue_list %}) and can write out the label {{ issue.label }} but if 
 write out {{ issue }} I simply get the bound field object written to

 Question is how do I get the html dropdown to display in the template??

 super(ItemAnalysisForm, self).__init__(*args, **kwargs)
 issue_choice = (('1', 'Reduced'),
 ('2', 'Maintained'),
 ('3', 'Increased')

 issues = item.issue.all()

 self.issue_list = []
 self.a_list = []
 # generate dynamic issue dropdowns...
 for issue in issues:
 self.fields['issue-' + str(issue.pk)] = 
 forms.ChoiceField(label=issue.**name , 
 choices=issue_choice, required=False)
 self.a_list.append(self.**fields['issue-' + str(issue.pk)])

 self.fields['text'] = forms.CharField(label='text', required=True,

Re: Django Interview Questions

[Amyth Arora]

after reading this guide it seems, the interviewer who asks such questions
himself is new to django or more importantly to programming. When it comes
to programming or codes , most of the interviewers would ask you logic
based questions instead of framework based questions as technologies like
django come and go on a daily basis. if your logic is clear, you can code
in any language based on any CMS' or frameworks.

Re: Easy way to temporarily disable the need to login

[Kurtis Mullins]

Actually, I've got another idea for you. You mentioned you wanted to simply
access using urllib. Maybe you could create a small script to extract a
CSRF token from the login page, login with a known (test) user, and
continue passing and extracting the CSRF token as needed?

Re: Easy way to temporarily disable the need to login

[Amyth Arora]

could you post the traceback and the respective code. Most probably you'll
need to disable all login_required decorators and also disable your user
login based template tags in all the templates for it to work properly.

Re: setting up Django Compressor

[Phil]

Hi Joni,

Yes I have 'compressor.finders.CompressorFinder' added. All the 
requirements are installed too I double checked them all, tried installing 
them all individually and it said they were all installed already. When I 
first setup the site it was using django1.3, but recently upgraded it. 

My static url setting is

STATIC_URL = '/media/'

and media is(for local setup)...

MEDIA_URL = 'http://127.0.0.1:8080/media/'

Not sure what's going on, might just try another compressor at this stage 
as I am not having any joy with this one.

TDD is not unit-testing

https://www.google.com/webhp?q=tdd%20is%20not%20unit%20testing


in short, it's like you've found: the tests you easily get with TDD
are more (but not exactly) like integration tests, because you test
features, not units.  The "test isolated units" mantra of unit-testing
requires different work.  There's nothing wrong in adding 'real'
unit-tests, but it's not required to do effective TDD.

I guess that since unittesting became so well known so long ago,
almost all test frameworks (including Python's and Django's) call
their base test class "UnitTest", but they're not; they're just tests.
 you make them feature tests, or integration tests, or unit tests, or
whatever kind of test.

now, about the pros/cons of unit-testing vs. other kinds of tests.
that's a whole debate that i'm not going to touch.

Re: Django Interview Questions

[Kurtis Mullins]

Yeah, I think this guide is a little crazy. If I'm getting interviewed
based on questions I can't answer without looking up relevant documentation
then I'd probably look bad even though the interviewer is the one lacking
the required knowledge to get the job done.

Maybe that's why I don't interview too often :) Just my 2 cents.

Looks like you just need a quick:

Re: Django Interview Questions

[Aaron C. de Bruyn]

I disagree with the "how to install" section.
I use Nginx and uwsgi to host Django applications.
There are other ways to deploy it too.

The section makes it seem like the only 'real' way would be Apache.

Lastly, it doesn't seem to touch on how a lot of people actually
install and deploy django projects.  My workflow is pretty simple
compared to what the install section says:

apt-get install python-pip python-virtualenv virtualenvwrapper
cd code
mkvirtualenv some-django-project
pip install django
django-admin startproject somedjangoproject
cd somedjangoproject
python manage.py startapp app1

Using virtualenv should also take care of the problem listed in
"Remove any old versions of Django".

I'd hate for someone to not get the job because they give a
"non-textbook" answer. ;)

I'm getting: 'NameError: "global name 'User' is not defined"' on the
above line. This is the same issue I was running into when I was
trying to hard code the initialization of a request.user object. Where
is that defined?

Re: Editable Tables

[MattDale]

I used this tutorial to get me going with the dhtmlx grid.   
http://www.rkblog.rk.edu.pl/w/p/using-dhtmlxgrid-django-application/ 
it's easy once you get the hang of it to make custom grids for each view, 
but not as cut and dry as it seems you are looking for.

Re: Easy way to temporarily disable the need to login

[anthony tresontani]

We are using a middleware to enforce a user login:

/class AutoAuthMiddleware(object):
"""
Middleware for testing purpose only.
Can enforce the user login.
"""

def process_request(self, request):
enforce_user = request.GET.get("enforce_user", None)
if hasattr(request, "user") and not enforce_user:
return

user = User.objects.filter(username = enforce_user)
if user:
backend = get_backends()[0]
user = user[0]
user.backend = "%s.%s" % (backend.__module__, 
backend.__class__.__name__) #fake authentication

login(request, user)/

You can add that to your testing environnement MIDDLEWARE_CLASSES.

Then you can just go to any url and add ?enforce_user=

I'm trying to do performance measuring. I have a list of all the urls

If any of your templates/views depend upon a request.user object, you'll
run into issues because that will not exist without "logging in". I'm not

Easy way to temporarily disable the need to login

[Larry Martell]

We have a django app that requires the users to login. For some
testing we want to do, we want to disable this so the app can be run
without logging in. Is there some way to easily do this? I've tried
commenting out all the @login_required decorations, but then I was
getting a 403. I tried commenting out the 'if not
controller.has_access' lines, but then I was getting 'Report.owner"
must be a "User" instance.' Before I hack up the code any more, is
there some way to just globally disable the need to login?

Re: Django admin runs out of memory with ForeignKeys to large tables

editable=False fields show up as readonly: after all, their data is
still interesting to look at, just should not be editable.

Looking at millions of read-only entries should lead to hours of

What good is that volume of data displayed to a user or admin? How about 
showing a rollup of the number of values and then allowing a 
click-through to a detailed display if necessary?

Re: Django admin runs out of memory with ForeignKeys to large tables

[Mattias Linnap]

I've found two solutions: setting "editable=False" in the model's
field definition (which removes the field completely from admin), or
adding it to readonly_fields list in the ModelAdmin (which keeps the
data visible).

Perhaps it will be possible to subclass ModelAdmin, and make all
editable=False fields show up as readonly: after all, their data is
still interesting to look at, just should not be editable.

Test driven development in Django framework

[jyria]

What is your experience? Is it worth it, and is it possible? 

I tried it and found it quite difficult to follow guideline of unit testing 
-- testing a unit of code, a class for example. Maybe Im just ignorant, but 
I didnt see, how can I create registration app only with unit tests. The 
only way I could drive implementation with tests was using more like an 
integration testing approach: calling requests with data and asserting that 
new user was registered and that form was valid/invalid etc, but this goes 
against TDD as I understand it. So should I not worry about pure "unit 
testing" approach and use django client http request to validate 
RegistrationForm. Or I should write unit tests for RegistrationForm class?

Django admin runs out of memory with ForeignKeys to large tables

[Mattias Linnap]

Hi all,

I have a model X that references another model Y with a ForeignKey.
There are very few Xs, but close to a million Ys in the database (and
it will grow considerably in the future).
This causes MemoryErrors in the Django built-in admin pages: the
ForeignKey is rendered as a select box field, and the admin attempts
to populate it with all million possible Ys.

What would be the recommended solution? The ForeignKey relationship
does not need to be actually editable in the admin, it's a simple
uniqueness constraint that should never change after an X is created.
I'm using the admin as more of a data browsing UI rather than a
management UI.

Thanks,

Mattias

Re: Validating GB telephone numbers in Django forms.

[g1smd.1]

Thanks for the reply and information.


The jQuery validation routines for GB telephone numbers contain significant 
errors and shortcomings. I already posted some patches correcting many of 
those problems at least a month ago, but they haven't been reviewed yet.


The new Python/django telephone number validation code I am proposing here 
is far more comprehensive and has much more detailed range and length 
checking. Similar code already works fine in PHP and Java elsewhere, but I 
am having trouble converting it all to Python. 

I have added some Python logic and code to the initial RegEx patterns that 
I posted yesterday, but I now need help to finish it off and get it 
working. I am not at all familiar with the Python syntax and the manual is 
somewhat terse and obtuse.

I had a problem with GitHub this morning, so the pull request is now at 
https://github.com/django/django/pull/324

The code so far, can be found at: 
https://github.com/g1smd/django/blob/master/django/contrib/localflavor/gb/forms.py

I'm guessing that someone proficient in Python could finish it off in a 
couple of hours or less.

Any volunteers?

Re: Output of form in Extjs

[Russell Keith-Magee]

Hi João,

Thanks for the suggestion, but this isn't something we're likely to
add to Django's core itself.

This is for two reasons. The first is that we have been specifically
avoiding any dependency on any particular database library. Django is
a server-side framework, so we don't want to impose any client-side
decisions on users.

The second is that we want to move away from the .as_* model, towards
a more flexible approach. There was a Summer of Code project last year
aimed at moving the forms library to a templates approach; that hasn't
come to completion yet, but the broader aim still stands -- rather
than try an encode every possible output format, we'd like to move to
a place where an end user can plug in any output format. To that end,
your ext2js renderer would be an end-user plugin, rather than
something built into Django itself.

Yours,
Russ Magee %-)

creating an object on saving another model to the database

[Martin Illgen]

Hello,

I've the following problem:

- I have a model (ModelA) with a primary key consisting of a foreignkey 
(ModelB - ID)

- *Databasestructure*
  TableA
  TableA_TableB - PK, BIGINT(20), FK TableB:ID
  NAME - VARCHAR(255)

  TableB
  ID - PK, AI, BIGINT(20)
  NAME - VARCHAR(255)

- *Django Models*

class ModelA(models.Model):
ModelA_ModelB = models.ForeignKey("ModelB", primary_key=True)
name = models.CharField(max_length=255)

class ModelB(models.Model):
id = models.BigIntegerField(primary_key=True)
name = models.CharField(max_length=255)

- *Django save_model of ModelA*

  def save_model(self, request, obj, form, change):
oObj = ModelB()
oObj.name = "TestIt"
oObj.save()

obj.ModelA_ModelB = oObj
obj.save()

- *Creating a new ModelA using the admin GUI I got the following error*

Django Version:1.4Exception Type:IntegrityErrorException Value:

(1048, "Column 'ModelA_ModelB_id' cannot be null")



 - *Model instance reference : 
Save
*

>>> b2 = Blog(name='Cheddar Talk', tagline='Thoughts on cheese.')>>> b2.id 
>>> # Returns None, because b doesn't have an ID yet.>>> b2.save()>>> b2.id 
>>> # Returns the ID of your new object.

Running the suggested Code above on my model (ModelB) I do not get the ID of 
the model after saving it. I got None for ID after saving my model. The 
Database contains the saved model.


What am I doing wrong? Why does my model not have a id after saving it to the 
Database?

kind regards

select_for_update() …

"Returns a queryset that will lock rows until the end of the
transaction, generating a SELECT ... FOR UPDATE SQL statement on
supported databases."

Postgresql handles this …

"If specific tables are named in FOR UPDATE or FOR SHARE, then only
rows coming from those tables are locked; any other tables used in the
SELECT are simply read as usual. A FOR UPDATE or FOR SHARE clause
without a table list affects all tables used in the statement. If FOR
UPDATE or FOR SHARE is applied to a view or sub-query, it affects all
tables used in the view or sub-query."

http://www.postgresql.org/docs/9.0/static/sql-select.html#SQL-FOR-UPDATE-SHARE

Django doesn't specify any tables when it generates a SELECT … FOR UPDATE query:

https://github.com/django/django/blob/master/django/db/backends/__init__.py#L585

Hope that helps

Tom

Re: with/include template pattern? seeking best practices

[Mike S]

The code `e.generalov` gave has been valid since Django 2.3: 


For more complicated context, you can also write an inclusion tag <
https://docs.djangoproject.com/en/dev/howto/custom-template-tags/#inclusion-tags>
 
and use that to render the inner template.

Re: Editable Tables

[Sait Maraşlıoğlu]

This is an example how to create and modify admin listing page: This 
explains better

class BookAdmin(admin.ModelAdmin):
list_display = ('title', 'publisher', 'publication_date')
list_filter = ('publication_date',)
date_hierarchy = 'publication_date'
ordering = ('-publication_date',)
filter_horizontal = ('authors',)
*raw_id_fields = ('publisher',)

Lets say , I want to use this kind of command for my frond-end, django handle 
the search fields and listing parameters.
only with my own table model, lets say its DHTMLX . at the end, I will have my 
view, generated with search options and
a few buttons to search,view,edit...
is it possible, not required to be ready to use, I just looking for a way to 
achieve it.

thx again.

Re: Editable Tables

[Sait Maraşlıoğlu]

DHTMLX  is looking great, I hope I can integrate it to my website.
Actually I was looking for a way to make it modular, let me explain.

Say, we have a modal named books, and it has fields, named 
'name,pages,author' . 
using a generic view or something, it will display a table vith its field 
types derived from my model and using a search box , and generated form. u 
can search your books. 
it should be modular so u shouldnt have same hassle to list and search ur 
other models.

it maybe possible, Django do that in its admin page, u can declare the 
search fields and the fields u can show in the listing page. its similar.

is it a dream? was this second version of I have a dream speech?
thx

should be declared in the array, and also the user details field
corresponding to that contents of the form, which a user fills, should
also be in array in the the models of the project.
I currently use to do this like:

class soil_oshr(models.Model):
date_of_testing = models.CharField(max_length=255)
type_of_str = models.CharField(max_length=255)
latitude_N = models.CharField(max_length=255,blank=True)
longitude_E = models.CharField(max_length=255,blank=True)
presence_1 = models.CharField(max_length=255)
presence_2 = models.CharField(max_length=255,blank=True)
submitted_1 = models.CharField(max_length=255)
submitted_2 = models.CharField(max_length=255,blank=True)
submitted_3 = models.CharField(max_length=255,blank=True)
site_name = models.CharField(max_length=255)
water_table = models.CharField(max_length=255)
depth_D = models.CharField(max_length=255)
water_table = models.CharField(max_length=255)
def __str__(self):
return self.date_of_testing

class soil_oshrForm(ModelForm):
class Meta :
model = soil_oshr
The thing i need that in case of above class "soil_ohsr" the choices
like "date_of_testing", "type_of_str", "latitude_N", and their values
which are in charfields, should be declared as array to avoid the
lengthy code.
If anybody tell me how i'll do it. Thanks in advance.

Authentication across projects

[yillkid]

Hi all .
I have two projects (A and B), different django installation, database, but 
same host.

I want the B projects share A project User database table.  
So A user account can login into B project site, but we don't create any 
user account in B project.
and I have already search many information about that.

1. REMOTE_USER
2. django multi database table
3. remote authentication

but I don't know what is the typical solution ?

I asked about this a couple of weeks ago and the correct solution is
to use a TransactionTestCase


Hi Mike,

I don't want to be explicitly test transactional behaviour, which I
think is the intention behind TransactionTestCase. I just want each test
running a transaction which rolls back on teardown. The django
documentation for TestCase seems to suggest that TestCase should provide
the behaviour I'm wanting:

/class/TestCase
Wraps each test in a transaction.

https://docs.djangoproject.com/en/dev/topics/testing/#testcase


In your earlier post you mention Django 1.2 but the reference you quote 
above is the dev documentation. There are differences in the docs but 
I'm not sure what the underlying code differences might be.


You are right though. If you want to test commits and rollbacks 
TransactionTestCase is your thing. By my reading of both 1.2 and dev 
docs, vanilla TestCase imported from Django on the other hand should 
handle commits and rollbacks itself.


As to your second database, I can't help because I have zero experience 
with multiple databases. However, I think I have recently seen a caveat 
in the docs somewhere about testing with multiple database. I haven't 
looked in the 1.2 docs for some time.


Mike


Explicitly calling connection._rollback() in a TransactionTestCase
unfortunately has the same behaviour and only calls ROLLBACK on the
'default' database.
