Re: install geodjango in windows 10

[Jani Tiainen]

Hi,

GeoDjango is actually built in as django.contrib.gis package so it's 
"batteries included".


To make it work you need to have certain GEOS and GDAL libraries. 
Easiest way to get them is install either MS4W stack or PostGIS 
librarios for PostgreSQL.


Also there exists few constraints for your models and of course, you 
need to use proper backend from gis.db.

Re: "Error creating new content types" with multiple DB router

[Jim T]

Carlton, we have the exact same issue you described.  It took a lot of 
searching to even find someone who has the same problem which led us to the 
conclusion that we just didn't understand how to perform migrations with DB 
Routers in play.  As you described, we have:

Database A - contains the schema for auth, sessions, content-type, models 
for app A
Database B - contains the models for app B

Migrations for app A function correctly.
Migrations for app B do not function correctly.

Our goal is the same as yours - to have models for app B (in Database B) 
store it's content-type in Database A, which is actually the point of 
having an "app" label in the content types table.  We follow the same 
suggestions and examples and yield the same error messages.

We are convinced the solution is some subtlety in the DB Router code that 
we missed and continue to investigate.  Did you ever find the solution to 
this?

Thanks
-Jim

Collectstatic and determine which files need to be updated by comparing their checksum

[Daniel Blasco]

Hi,

In my particular case, I'm using django-storages to upload my static files 
to Amazon S3. I'm serving my application from Heroku.

In my local development, when I run collectstatic for a second time just 
after the first one, no files are being uploaded to S3 because 
collectstatic checks for the modified_time to determine if the local files 
are newer than the ones in S3. That's fine so far.

The problem is when I deploy to Heroku. Collectstatic is being executed 
from the Heroku server and absolutely all the files are always being 
uploaded to S3, even the ones that have not changed. This is because during 
the deployment Heroku creates a full copy of the source code, and therefore 
all the files have a new modified_time. In my case, it takes almost 10 
minutes to upload ~1000 files for each deployment.

Also, imagine the situation where the modified_times are not being changed 
and I wanted to upload older versions of the static files. I wont be able 
because storage wouldn't allow to upload files with an older modified_time.

I think that a more accurate way to check if a file needs to be replaced 
could be by comparing their checksum/hash and offer this feature for all 
the Storage subclasses. To preserve backwards compatibility, in 
collectstatic command first determine if the storage subclass implements a 
checksum generation and otherwise fallback to modified_time comparison.

What do you think, is this something that makes sense?

Re: Multidimensional form requirements

[C. Kirby]

If you are already add/deleting in place using ajax you can use that to 
your advantage. Don't think of it as a single form - each ajax capable 
component (profile, extra1, extra2, extra3) is a separate form. You have a 
view that populates your template with multiple forms - the profile and 
each extra. Then each of those has an ajax endpoint for update/delete. You 
can also have and add extra button that has an endpoint that provided the 
form via ajax, and its save endpoint is the save/update endpoint you 
already have.

Deploying a Django 1.9 project

[Nick Jenkins]

I've been developing a site with Django 1.9 with Python3 and I'm hitting a 
wall when trying to deploy it to a hosting service. I currently have a 
shared service plan through BlueHost and I'm having trouble getting 
everything to work right. In talking with BlueHost they stated they only 
support Python 2.7 and Django 1.4. So, I'm trying to determine how best to 
proceed.

After reading many old walkthoughs on Django installs here's is what I've 
tried so far:
1. I was able to get Python 3.5 and Django 1.9 installed as a local source. 
Then after an error 500 page, I realized FastCGI was not longer supported.
2. Then after many linking errors I was able to get mod_wsgi installed with 
Python3.5 having shared libraries. The trouble is BlueHost shared services 
doesn't have root access.

(That list seems so short when compared to the actual time and number of 
tries it took to get this far)

I guess the question I'm trying to ask is: Should I switch hosting 
companies, stay with Bluehost and upgrade to a VPS or am I missing 
something simple in the configuration and I can actually get this whole 
mess to work?

Any help would be appreciated.

Re: Deploying a Django 1.9 project

[Devrhoid Davis]

Hi Nick,

In my limited experience, you seem to have two options:

1. You can switch to another host who will grant you root access (such as
linode.com) and proceed to install django and python with the required
dependencies.

OR

You can downgrade to Python 2.7 and use django 1.7 with your current
BlueHost plan. The issue of not having root access will however remain.

I hope this will help you in choosing a way forward and to getting your
project completed.

Best regards,
Devrhoid

Migration bug in 1.9.5?

[Aaron C. de Bruyn]

* My project has been around since the Django 1.2 days.
* Some time around 1.8.x I ran squashmigrations and everything worked
perfectly.
* I've done lots of migrations since then.
* I updated the app to Python 3.
* Everything was working perfectly

I just did my first makemigration under python 3.  Specifically I added a
Boolean 'enabled' field to a model.

The migration appears to have been created properly, but when I try to run
the 'migrate' command, it tries to apply
0001_squashed_0009_auto_20150109_1447.

I tried to fake it by running 'manage.py migrate myapp 0001 --fake' and it
says it applied (faked).
Running 'manage.py migrate' shows it trying to apply the 0001_squashed...
migration again.

I also tried using the --fake-initial flag with no luck.

'showmigrations' show every migration since the squash has been applied,
just not the squashed migration or the most recent one I just created:

myapp
 [ ] 0001_squashed_0009_auto_20150109_1447 (9 squashed migrations)
 [X] 0010_auto_20150109_1824
 [X] 0011_auto_20150818_1946
 [X] 0012_auto_20150829_1610
 [X] 0013_auto_20150829_1610
 [X] 0014_auto_20150829_1618
 [X] 0015_auto_20150829_1618
 [X] 0016_remove_internetprovider_old_phone
 [X] 0017_office_linked_location
 [X] 0018_auto_20150829_2345
 [X] 0019_office_pib_version
 [X] 0020_auto_20150908_1643
 [X] 0021_internetservice_notes
 [X] 0022_office_last_router_backup_alert
 [ ] 0023_auto_20160412_1433

How can I get the system to recognize that 0001_squashed... has been
applied already?

Thanks,

-A

Totally get it, but its a necessary evil in my daily duties.

To clarify, I said I used it. I didn't say I liked it. MS is all cordoned
off in its own VM at work. Everything else I personally run is either
Debian (servers) or Xubuntu (desktop/laptop). My laptop dual-boots
Xubuntu/Win7, is the only Windows machine in my house, and I'm pretty sure
I'm about 6 months behind on my Win7 patches because it hasn't been booted
in that long.

But hey, maybe I'll finally get around to upgrading to Win10 and installing
Ubuntu/Bash, and then I'll never need a native Linux installation again,
right? ;-)
