Re: Django TinyMCE external_image_list_url breaking admin urls

[Chris Davies-Barnard]

Hi James,

Thanks for the reply.   So I uncommented the line which now looks like: 

*mce_attrs={ 'external_image_list_url': reverse('imagelist')},*

and after restarting apache I get this.

Page not found (404)Request Method:GETRequest URL:
http://csmatrix.local/admin/main/page/add/

Using the URLconf defined in CSMatrix.urls, Django tried these URL 
patterns, in this order:

   1. ^$ [name='cover']
   2. ^m/
   3. ^curriculum/
   4. ^unitsoflearning/
   5. ^studyprogramme/
   6. ^gallery/
   7. ^reprographics/
   8. ^accounts/
   9. ^login/$
   10. ^logout/$
   11. ^tinymce/
   12. ^admin/doc/
   13. ^admin/ ^$ [name='index']
   14. ^admin/ ^login/$ [name='login']
   15. ^admin/ ^logout/$ [name='logout']
   16. ^admin/ ^password_change/$ [name='password_change']
   17. ^admin/ ^password_change/done/$ [name='password_change_done']
   18. ^admin/ ^jsi18n/$ [name='jsi18n']
   19. ^admin/ ^r/(?P\d+)/(?P.+)/$ 
   [name='view_on_site']

The current URL, admin/main/page/add/, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django 
settings file. Change that to False, and Django will display a standard 404 
page.

It makes no difference if I try and run it though runserver or apache - 
same result.  All my admin urls are broken!   I know this is not much help 
- is there another way of getting a traceback?

Regards

Chris

Re: Django TinyMCE external_image_list_url breaking admin urls

[James Schneider]

Do you have an app named 'main'? Is it part of INSTALLED_APPS? And is the
Page model properly registered with the admin site?

How exactly did you reach that URL? Does the admin work if you just use
/admin/?

Re: Django TinyMCE external_image_list_url breaking admin urls

[Chris Davies-Barnard]

Hi James,

Well,  I seem to have made it work by removing the reverse command all 
together.   

mce_attrs={ 'external_image_list_url': 
'http://csmatrix.local/gallery/imagelist/'},

obviously this is not a very elegant solution but its working.I also 
noted that I could not use tinymce 4 as the image box failed to load 
period.   I'm also wondering whether I could/should use reverse_lazy 
because of when this line is being called.

Cheers for your help.   I'd be interested in your thoughts.

Chris

Re: Django TinyMCE external_image_list_url breaking admin urls

[Chris Davies-Barnard]

Hi James,

Thanks for the response.   I have just replied to say its working in one 
sense.   Main is my pages, blog and homepage app and then mediamanager is 
the app that manages images etc uploaded into the media folder.   I can 
create albums which are inserted using wordpress style shorttags into pages 
and posts and I can set featured images for both.  It all works very nicely 
for me except being able to easily insert single images into the middle of 
pages.

When I went to the main admin page with reverse included it gave a 
traceback that looked the following.

I would obviously like to get it working correctly but for now will leave 
it as is and move on.

Thanks for your help.

Chris

Actually it is normal if i have duplicate, because at each "Categorie" loop 
in template i load different data, but if i can optimize this with 1 
request i think will better, i look at cache funcionnality too for visitor 
not have to loads these data at each pages (because this menu is here in 
all pages of the website), but its an other thing.

Hi Gary,

In your second example:

you have what I would call a "global" static files directory. Files from
this directory will only be found if you configure that directory in your
settings:

STATICFILES_DIRS = (
 os.path.join(BASE_DIR, "static"),
)

This is because that directory is not part of any app that is listed in
INSTALLED_APPS.

BASE_DIR is the top-level "archive" directory, by the way (the first
"archive" in the tree).

I hope this helps.


Because this gets asked so often, I am trying to  to sump it up here:

https://fleschenberg.net/django-staticfiles/

I'd love to hear your feedback about this article, i.e. if it clarifies
things for you, or how to improve it.

Thanks for the tips. I read your 'In a nutshell" . Good work. Now, 
getting into setup philosophy, it occurs to me that it would be nice to 
have  global static files for such things as a style.css file since the 
file should set the style of your whole web site. I suppose that one 
could put a copy of the file under each apps static folder but change 
control would be horrible. Could I set up both a global static folder 
and then have a static folder under each app? Being rather new to this 
rats nest (great framework all the same) I'm probably skating on rather 
thin ice here. Be kind.


As to your comment on the first tree, I think I created the problem 
while cutting and pasting. The actual project works - mostly.


A comment on "6 An alternative approach". This actually my case. When 
you say that the app listed first takes precedence.


Looking forward to your comments.

Re: Where does the static files reside

[Andreas Kuhne]

Hi Gary,

You can certainly setup a global static files location. All you need to do
is add a path to STATICFILES_DIRS in your settings file. However, that is
not really necessary. All files that are in a static directory in one app
are accessible in other apps. You can create an app that contains css and
js files needed for the other apps and concentrate them in one app. The
only thing you need to think about is if you want to make sure that the
apps are completely unconnected.

Regards,

Andréas

Managing and synchronising users on multiple sites

[Stodge]

I have several Django sites and I need to synchronize user accounts across them 
all. I need the ability to create the same user on all sites at the same time 
and also to keep their info in sync. The servers are in different locations in 
DMZs and can't open connections to external servers. So no third party access. 
I thought I could write a Java app that uses a REST API to query and update 
accounts to synchronize them but that opens a security issue as I have to 
expose the ability to read/write passwords. I can't think of any other 
solutions - any ideas? Thanks

finding information on modules, imports, etc.

Maybe I'm using the wrong terminology but after a gazillion searches, I

Re: Managing and synchronising users on multiple sites

[Gergely Polonkai]

How about an SSO solution hosted at one of the sites? When the user logs
in, the site authenticates them against the SSO, and fetches user data. See
Stack Exchange sites (Stack Overflow, Server Fault, etc) as an example.

It's a bit unclear what you want to do. Could you write a use case? I'm
afraid of an XY problem here…

Thanks for your suggestions, Carl.  I'll check them out as it sounds

Django on CentOS

[Robin Fourcade]

Hello,
I'm trying to run my django project on my CentOS server.

I followed this tutorial 
: 
http://www.science-emergence.com/LeWebFrameworkDjango/DeployerUneApplicationDjangoSurCentos/#deployer-votre-application-django

And at the end, they say that I just have to enter my server IP address and 
I'll have access to my project, but I only have a 500 error: *Internal 
Server Error*

However, when I shutdown apache and run: python manage.py runsever 
0.0.0.0:80, everything works fine.

How is it possible to do without runsever, because I read somewhere that it 
what not the right thing to do.

Can somebody help me ?

Thanks,
Robin Fourcade.

What do your Apache access and error logs have to say?

Then it is likely an issue with your Apache setup.

You are correct. Apache or another production grade web server should be
used when your site is made available on the Internet.

Re: Managing and synchronising users on multiple sites

The servers are in DMZs in different cities. I don't control the firewall

Re: Managing and synchronising users on multiple sites

[Gergely Polonkai]

I meant web based SSO :) The aforementioned Stack Exchange sites work like
this; when you authenticate to one of their sites, you actually
authenticate to Stack Exchange, which sets a cookie that is processed by
the sites. This can be done by one of the already available web servers
(although a separate one would be the best)

Re: Django on CentOS

[Gergely Polonkai]

Hello,

no, the problem is here:

[Sun Nov 08 14:46:43 2015] [error] [client 109.10.154.52] ImportError:

It seems that your settings file is either missing, or Apache is
misconfigured so mod_wsgi can not find it.

Re: duplicated queries

[James Schneider]

The reason that you are seeing multiple hits on the database is due to the
way that your template loops are built. The {% with %} statements are
calling a method on your model, which is returning a fresh queryset for
every iteration of the for loop (which is then compounded by the inner {%
with %} calls and more inner {% for %} loops. The fresh querysets are then
evaluated, causing excessive (and unnecessary) database hits. Any
prefetch_related() action within your view would result in the behavior
you've seen, only adding more database queries to pull data that is never
used since you are requesting fresh querysets on every loop in the template.

I believe what you'll need to do is filter and prefetch all of the rows
from the various models using Prefetch() objects. Let's see if I can work
this out, YMMV, I'm typing this as I go based on the models you sent out
almost 24 hours ago:

###
# view code - see
https://docs.djangoproject.com/en/1.8/ref/models/querysets/#prefetch-related
section regarding the Prefetch object
###
# add this to your imports
from django.db.models import Prefetch

# Note that these Prefetch() objects act as your filters for the related
objects, so we don't need to add them to the Categorie filter
pf_souscategorie = Prefetch('souscategorie_set',
SousCategorie.objects.filter(visible=True)) # prefetch only visible
SousCategorie's
pf_theme = Prefetch('souscategorie_set__theme_set',
Theme.objects.filter(visible=True)) # prefetch only visible Theme's
pf_soustheme = Prefetch('souscategorie_set__theme_set__soustheme_set',
SousTheme.objects.filter(visible=True)) # prefetch only visible SousTheme's

# Here were filtering on visible Categorie's, related objects are filtered
by the Prefetch() objects above
categs =
Categorie.objects.filter(visible=True).prefetch_related(pf_souscategorie,
pf_theme, pf_soustheme)

###
# template code - I removed the blank lines and reduced the indentation for
readability in an email.
###

{% for categ in categs %}
  {% with currscat=categ.souscategorie_set.all %}
 {{categ.nom}}
  {% if currscat %} # This line hit database
  
   {% for souscateg in currscat %}
   {% with currth=souscateg.theme_set.all %}
 
{{souscateg.nom}}
   {% if currth %} # this line hit database
 
   ..
   {# Assuming you would loop through currth here to get
all of the soustheme's, use same strategy as above, otherwise, remove the
reference to pf_soustheme above in the view #}
 
   {% endif %}
 
   {% endwith %}
   {% endfor %}
  
  {% endif %}

  {% endwith %}
{% endfor %}


Hopefully that works out for you. I did test Prefetch() against multiple
levels of reverse relationships in my own project, and it appeared to work
as expected.

Another related but tangent thought: Your parent and child models (ie Theme
and SousTheme) appear to be the same model, but one is considered a 'child'
of the other purely by virtue of the FK relationship. You could potentially
eliminate the 'Sous' models and use a M2M relationship with 'self' in
asymmetric mode to capture the parent/child relationship. It would save you
a table and a reverse relationship query in situations like this. It would
also allow you to add more levels to the relationship (parents, children,
grandchildren, and so on). Just a thought.

https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.ManyToManyField.symmetrical

You could also look at implementing an MPTT model, which is often used for
hierarchical objects like categories.
http://django-mptt.github.io/django-mptt/overview.html#what-is-modified-preorder-tree-traversal
as an example.

HTH,
