Re: two django sites at different revisions with apache

[James Schneider]

I don't see why not. For Apache, you would just place the
relevant WSGIScriptAlias and WSGIPythonPath inside of your VirtualHost
elements. You would need to be cautious about running a single WSGI process
though, since the first site settings read will apply to all of your Django
sites (which is probably not what you want), as explained at the end of the
section in the Django docs here:

https://docs.djangoproject.com/en/1.7/howto/deployment/wsgi/modwsgi/#basic-configuration

Django recommends running Apache WSGI in daemon mode though, so you
shouldn't need to worry about the settings files clashing:
https://docs.djangoproject.com/en/1.7/howto/deployment/wsgi/modwsgi/#daemon-mode

Haven't toyed enough with the others to know whether or not it is possible,
but I'm sure all of the major servers have similar separation strategies
for exactly this scenario.

A quick Google shows that Nginx/uWSGI can support multiple sites through
the use of Emperor Mode and separate vassal configuration for each site,
which sounds very similar to Apache/mod_wsgi daemon mode.

Re: upload_to for ImageField changes name of file being uploaded

[Tom Evans]

It looks like it has already been answered multiple times - you cannot
upload a file in to a subdirectory of MEDIA_ROOT and have its name
attribute be the base file name. The name attribute of a FileField is
the path to the file relative to MEDIA_ROOT*. If you want to store
files in subfolders of MEDIA_ROOT, then obviously, the name attribute
will not consist of just the file name of the uploaded file.

If you want to know or use the name of the file, use
os.path.basename() on the name attribute.

Cheers

Tom

* This isn't actually true, but is close enough to the truth as makes
no difference. It is in fact relative to whatever "storage engine"
that FileField uses; the default storage engine behaves as I have
described.

It is not doing any such thing as "overwriting the default User model". 
That is a Manager: your first port of call should have been the 
documentation for model managers, which is here:
https://docs.djangoproject.com/en/1.7/topics/db/managers/

If there's anything you don't understand after having read that, please 
come back and ask a more specific question.

Re: Migrating to initial migration: "ORA-00955: name is already used by an existing object"

[Carsten Fuchs]

Hi all,

Am 02.02.2015 um 22:50 schrieb Carsten Fuchs:

It seems that creating the initial migrations with `makemigrations`
works well, but the first run of `migrate` aborts with error
"django.db.utils.DatabaseError: ORA-00955: name is already used by an
existing object". Please see the full output below.


A quick update:

Running `migrate` with very verbose output (`-v 3`) does not provide any 
relevant extra information, just:



[...]
Running migrations:
  Applying Lori.0001_initial...Traceback (most recent call last):
[... same as before]



Also, I re-tried with `managed = False` added to each model's Meta 
class, but to no avail: the error is exactly the same as reported in my 
previous post. (With `managed = False`, `makemigrations` lists all the 
models, but not the previously indicated constraints or the fields. The 
exception with `migrate` about ORA-00955 remains the same, though.)



Any help or hints would very much be appreciated!

Many thanks and best regards,
Carsten

Problem with uwsgi

[Andreas Kuhne]

Hi all,

We are running our website with nginx and uwsgi at the moment. It is a
django 1.7.4 application and it has been running perfectly for a couple of
months. Now however we are getting some errors that I can't really explain.

The errors always appear after uwsgi has done a respawn of a process. Then
we can get 4-5 errors with very strange behavior. Things like "dict has no
method 'startswith'". They aren't errors in the code because the code will
run perfectly before and after these errors. We also used to get these when
we deployed a new version of the website and then restarted uwsgi (by
sending a kill signal to the main process).

Has anyone had the same problems and if so, does anyone know how to remedy
it? We are getting a lot of false error mails and it's starting to get
annoying. Also I don't know how our customers are affected when this
happens, but it's probably not good.

Regards,

Andréas

Hi, ensure you are running a stable uWSGI version 1.4.x or 2.x, older
versions have serious bugs. Eventually paste your uWSGI configuration

We are running uwsgi version 2.0.7 so I hope that's ok?

module=suitopia.wsgi:application
master=True
pidfile=/tmp/canvas.pid

Picking a random post here. When asking questions, please:

* Describe what you're trying to achieve, and what you have already tried
* Post the relevant code, if you have code that's not working
* Post the error messages, if you get error messages

These are really simple things that raise the chance you'll get helpful answers 
from this list.

Django Wysiwyg and images (Summernote or Froala)

[David Mutton]

Hi,
I've been trying to integrate a WYSIWYG editor into my Django project. I 
first started with Summernote and I had no issue integrating the it into 
admin or a form. I followed the instructions on their github and everything 
works great except image uploading and inserting. The file is uploading (I 
can see it in the filesystem) but it does not show up in the editor or in 
the resulting html.

I thought it was just Summernote and so I switched to Froala but I'm 
getting the exact same behavior. Is there something I'm missing with image 
upload inside a wysiwyg?

Re: Pillow on QPython3

[Russell Keith-Magee]

Hi Adewale,

Installing Pillow is always a bit of a struggle, because it involves native
code - the pieces of pillow that do the actual image processing rely on
system libraries for handling JGEG, PNG etc. If the makers of QPython
haven't included Pillow (or PIL) in their build, you're going to be
fighting an uphill battle to get it working. If you're not comfortable
dealing with Autoconf files and C compilers, you're probably not going to
get it working.

That said - Django should run without installing Pillow, as long as you
don't try to use an ImageField. Skip over whatever step is telling you to
install Pillow, and see what happens when you work through the tutorial.

Yours
Russ Magee %-)

Tests and temp tables

[Larry Martell]

I have a django app that uses a temp table. In the real world this is
no issue, as each invocation of the app runs in its own MySQL session
so there cannot be any conflict with the temp tables. But in my tests
there are multiple requests sent, and apparently they are all in the
same session, as on the second request I get an error because the temp
table already exists. I tried logging out between requests, and I
tried creating a new Client instance for each request, but I still got
the error. Then I tried deleting the Client object, but I got Client
object has no attribute __del__.

What I can do so that each request in a test has its own MySQL session?

Context processors, am I doing them right?

[Dean De Leo]

Hi,
I am new to Django and I am still going through the tutorial. I've tried
to set up a context processor for the following scenario, and I would
like to obtain some confirmation if this is a proper solution or I am
doing some mess..
In my base template with a header there is a navigation bar. A single
button should be highlighted among the others depending in the current
section / page in the website:


Blog
Projects
...


What I thought so far was to register a universal context processor:

def navbar_selected_menu( request ):
items = {"blog": "", "about": ""}
target = request.META["PATH_INFO"]

def select( key ):
" Select the given key in the dictionary item "
nonlocal items;
items[key] = ' class="selected"';

if re.match( "(^/$)|(^/blog$)|(^/blog/)", target):
select("blog")
if re.match(  "^/about\.s?html", target): # about
select("about")


return {"navbar": {"selected": items}};

and add to all links a variable such as Blog.

Is this solution appropriate or does it exist something clearer?

Moreover, is there the chance to pass explicitly a variable from the url 
mapping to the context processor ?

Kind regards,
Dean
