My setup looks like this:

Django 1.5

Project/app structure:

mysite/ # Project root
 mysite/
  settings.py   # INSTALLED_APPS includes 'foo', a reusable app
 templates/
  base.html # Project base template, includes jQuery &
# Bootstrap JS for project
 static/# Static assets for project
  js/
   jquery.js
   bootstrap.min.js


foo/# Reusable app
 templates/
  foo/
   index.html   # app template, extends 'base.html'. Requires
# and includes jQuery and Bootstrap JS for app
 static/# Static assets for 'foo' app
  foo/
   js/
jquery.js
bootstrap.min.js
app.js

So when 'index.html' from the foo app is rendered, the JS imports look
like this:


  
  

  
  
  
 
  


...because both the project and the reusable app are using jQuery and
Bootstrap JS, loading them twice on the same page results in screwed
up JS behavior.

Seems interesting, I'll look into it more. To be honest, I think I'm
looking for a best practice rather than a solution; how are others
managing redundant JS includes when combining their own projects and
reusable apps? I imagine there's no app required to do this
intelligently.

Re: Multiple versions of Django

@all, thanks for their help but my requirement is to use multiple 
versions of django on single server. I have to use it apache web server.
Here is the full scene. 
I have django 1.4.2 installed on ubuntu server which uses apache. 
There are several django based applications installed on it. All of 
them are working on django 1.4.2 . But recently I have developed an 
another application using django 1.5.2. Now I have to install that 
application on server, but problem is that, I can not remove django 
1.4.2 from server. For this purpose, I have tried virtual environment 
using steps given in following link:
http://serverfault.com/questions/413879/how-can-i-run-two-django-versions-in-the-same-server

But when I wish to use to application, I have to switch on virtual 
environment and start then django server. I want that app to run without 
using django server. 
Hope that I am able to explain the problem. If there is any confusion, please 
ask.

None in Python corresponds to NULL in SQL. SQL defines that NULL != NULL.
So when checking for unique values the database will not consider two NULLs
to be the same value; the NULLs will be considered to be different and will
not violate the unique constraint. The Django code is doing the same check
for uniquess that the database will be enforcing. There is no way I know of
to make a database enforce uniqueness among NULL values...

Re: Using unique_together with foreign key fields which may be None

[Berndt Jung]

Well, I may have answered my own question.  It looks like per the SQL 
standard NULL values are unique.  Here from the postgres docs:

In general, a unique constraint is violated when there are two or more rows 
in the table where the values of all of the columns included in the 
constraint are equal. However, null values are not considered equal in this 
comparison. That means even in the presence of a unique constraint it is 
possible to store duplicate rows that contain a null value in at least one 
of the constrained columns. This behavior conforms to the SQL standard, but 
we have heard that other SQL databases may not follow this rule. So be 
careful when developing applications that are intended to be portable.

So it looks like django is doing the right thing although it seems pretty 
unintuitive.  It looks like I may have to modify the models afterall.

Using unique_together with foreign key fields which may be None

[Berndt Jung]

Hi,

I'm having trouble using the unique together constraint with a a field 
which may be None.  Given this model:

class Rule(models.Model):

internal = models.BooleanField(default=False)

port_range_from = models.PositiveIntegerField(null=True, blank=True)
port_range_to = models.PositiveIntegerField(null=True, blank=True)

# either cidr_ip or src_group for ingress rules
cidr_ip = IPNetworkField(blank=True, null=True)
is_ingress = models.BooleanField(default=True)

# a security group is used as src in this rule
src_security_group = models.ForeignKey(
SecurityGroup, to_field='uuid', null=True, blank=True)

class Meta:
app_label = "nomos"
unique_together = (
('port_range_from', 'port_range_to', 'cidr_ip', 
'src_security_group', 'is_ingress'),
)

Now in this instance src_security_group may be None OR cidr_ip may be None. 
 In this case they are mutually exclusive.  Regardless I want to use the 
unique_together to ensure that no two identical rules are created. 
 However, in the django models/base.py code the following logic is in 
_perform_unique_check:

lookup_kwargs = {}
for field_name in unique_check:
f = self._meta.get_field(field_name)
lookup_value = getattr(self, f.attname)
if lookup_value is None:
# no value, skip the lookup
continue
if f.primary_key and not self._state.adding:
# no need to check for unique primary key when editing
continue
lookup_kwargs[str(field_name)] = lookup_value

# some fields were skipped, no reason to do the check
if len(unique_check) != len(lookup_kwargs):
continue

Because the lookup_value of a null field is None, the validation check is 
aborted entirely.  This seems wrong to me, and I'm wondering if I'm doing 
something wrong here.  Redefining the models is not something I can do at 
this point.

What is that property/lambda stuff supposed to be doing? You *seem* to be 
trying to define something that will get a Candidate from a user, but I 
don't understand why you're wrapping it in 'property', and then of course 
you don't ever call it or pass it a User. If you did call it, you'd no 
doubt get multiple errors, for example `get` only returns a single object 
so indexing it with [0] is bound to raise an exception.

Also, you might want to explain the relationship between a Candidate and 
the Student/Teacher models you've shown above.

[Frank Bieniek]

Please try, django-userena, or django-registration,
both deal with userdetails.

Re: Multiple versions of Django

[Peter Herndon]

I would suggest using separate virtual environments, each with gunicorn 
(http://gunicorn.org/) installed into the venv. Run gunicorn listening on a 
different port per venv, start all your venvs under supervisord 
(http://supervisor.org/), and proxy them behind nginx (http://wiki.nginx.org/).

try not to use the same value ('about') for the name attribute of the

not sure it helps the situation though.

Can you perhaps post the template fragment that renders the
field, and also the rendered HTML?

Re: Textarea and initial value

[Marcin Szamotulski]

Sure here it is how the form is render:

 

 
Submit

 
Format:

Text
reStructuredText
MarkDown



Profile image:
 

 



I use jinja2 template language and it is rendered with

 {% csrf_token %}
{{ render_field(aboutform.about, label=False) }}
{{ render_field(aboutform.format) }}
 {{ render_field(aboutform.image) }}



where render_field is a simple macro:

{% macro render_field(field, inline=True, after=True, label=True) -%}
{% if inline and field.field.widget.__class__.__name__ ==
'CheckboxInput' -%}
 {{ render_boolfield(field, after) }}
{%- else -%}
{% if label -%}
{{ field.label_tag() }}
 {%- endif %}
{{ field.as_widget() }}

 {{ field.errors.as_ul() }}

{%- endif %}
{%- endmacro %}

Thanks,
Marcin

Re: Multiple versions of Django

[Bill Freeman]

Virtual environments can, indeed, be used under Apache.  I presume other
front ends can also handle this.

For Apache, the separate VE's need to be in separate deamon process groups,
so that their sys.path settings can differ.

The primary thing that virtualenv does for you is tweak sys.path, usually
by setting PYTHONHOME, but there are other ways.

If using a new enough mod_wsgi (3.4 or later, I htink), there is a
python-home option to the WSGIDaemonProcess directive.  Otherwise you can
fiddle sys.path in your wsgi script file.  If you are using
Apache/mod_wsgi, there is lots of useful documentation and a pointer to
their mailing list at http://code.google.com/p/modwsgi/

Re: Multiple versions of Django

Yes, use something like VirtualEnv, it allows you to separate website
environments and requirements and it has nice additionals to help you
publish

Django South - SyntaxError: invalid syntax (, line 1)

[Ivan Goncalves]

Hi 

I'm having trouble with the South.

In the model below:

class Carrier (models.Model):
 name = models.CharField (max_length = 40, blank = False, null = False, 
verbose_name = 'Name')
 user = models.ForeignKey (User, blank = True, null = True)

 def save (self, force_insert = False, force_update = False):
 self.nome self.nome.upper = ()
 super (Carrier, self). save (force_insert, force_update)

 def __ unicode__ (self):
 return u '% s'% (self.nome)

the error occurs when i run the migrate after South on the app.
SyntaxError: invalid syntax (, line 1)

But if my model does not have the user field, then the error message does 
not occur, as shown below:

class Carrier (models.Model):
 name = models.CharField (max_length = 40, blank = False, null = False, 
verbose_name = 'Name')

 def save (self, force_insert = False, force_update = False):
 self.nome self.nome.upper = ()
 super (Carrier, self). save (force_insert, force_update)

 def __ unicode__ (self):
 return u '% s'% (self.nome)


I need the field User. What I have to do ?

Thanks a lot.

Ivan

Can you perhaps post the template fragment that renders the field, and also 
the rendered HTML?

xadmin override base_site.html

Hi,

has someboday a clue why I get this error.
Without the modifications xadmin works fine, but if  I copy  for 
modifications in my ../templates/xadmin/base_site.html
I got the error below.

If I cut this *if step*  the template is loaded but without surprise in 
fragile form. Has anybody an idea where this menu_template
comes from , can't find it yet?  With the complete  template/xadmin folder 
in my ../templatesthe problem is still the same.

Thanks Christian

I don't do anything odd: I simply modify it by typing in side textarea.
The page has a very simple JavaScript which does not do anything with
the textarea (though I double-checked that turning it off does not
improve the situation).  Inspecting the request reveals that the data is
indeed submitted twice (thus django correctly interpret the situation).

The form is using enctype='multipart/form-data' since it is also used to
submit a file, though leaving only the textarea inside the form and
removing the enctype does not help.

I also checked this in both firefox and chrome and both show that the
POST data for this textarea is submitted twice.

Any ideas?

Thanks for help,
Marcin

How are you "modifying the initial value to 'new value' "? If you're simply 
typing in the field to replace the text that's there, there's no way that 
request.POST can contain the original data. You seem to be doing something 
odd somewhere.

Re: Dealing with redundant JS inclusions at template levels

[Dariel Dato-on]

You can consider using Django Sekizai to manage your Javascript and CSS 
imports:

https://django-sekizai.readthedocs.org/en/latest/

Hope that helps!

Re: Not able to create an simple application using DB (syncdb error)

[Bill Freeman]

Have you said which version of Django you are using?  (If so, it slipped
past me.)

Is this all code that you wrote yourself, or did you copy some or all it
from somewhere?
If copied, under what version of Django was it being used?

Have you gone through and understood the tutorial for the version of Django
you are using?

Please, in a terminal window, try:

   cd c:\Users\gsherieff\blog1
   python
   import blog1.settings

What is printed?

 And where is your settings.py file?  If it is in the same directory as
 manage.py, and it is a reasonably current Django (1.4, 1.5), then it's in
 the wrong place.  It belongs in a sub-directory named 'blog1', along with
 your urls.py, wsgi.py and an empty __init__.py .

Re: Dealing with redundant JS inclusions at template levels

[Rafael E. Ferrero]

I Dont know your design, usually i include the js library on base template
and my apps templates extend from that... or just put another base template
for every app...

If you have some example code or tell us why you do that then we be more
helpfull

See ya

Dealing with redundant JS inclusions at template levels

[Darren Spruell]

Spent a bit of time debugging some faulty JavaScript library
functionality before I realized that I had included the library at
multiple levels in the project - first site-wide in the base template,
and then within a app. I think I ran into this:

http://stackoverflow.com/questions/4891278/what-is-the-danger-in-including-the-same-javascript-library-twice

Is there a good design pattern to this situation, bearing in mind a
need to include JS libraries at project level and a desire to use apps
that include the same libraries in an attempt to be reusable?

Looking at jQuery and Bootstrap for this.
