Re: ProgrammingError: relation "django_content_type" already exists

[Mike Dewhirst]

Still not getting very far. The error below* keeps turning up. Further 
to this, I ran migrate with --list and --settings=ssds.settings.dev and 
it returns ...


admin
 [ ] 0001_initial
auth
 [ ] 0001_initial
 [ ] 0002_alter_permission_name_max_length
 [ ] 0003_alter_user_email_max_length
 [ ] 0004_alter_user_username_opts
 [ ] 0005_alter_user_last_login_null
 [ ] 0006_require_contenttypes_0002
contenttypes
 [ ] 0001_initial
 [ ] 0002_remove_content_type_name
sessions
 [ ] 0001_initial
sites
 [ ] 0001_initial

The 1.7 docs say ...

The --list option will list all of the apps Django knows about, the 
migrations available for each app and if they are applied or not (marked 
by an [X] next to the migration name).


Apps without migrations are also included in the list, but will have (no 
migrations) printed under them.


None of my five apps are listed.

Running makemigrations returns "No changes detected" so I suppose the 
Django ones were done when I first ran manage.py migrate. That's only a 
guess.


I'll keep reading the docs.

Thanks in advance

Mike

This is my first stab at upgrading directly from Django 1.6.11 to 1.81c

idea? Is there some step in 1.7.x which eases the path to 1.8.x?

On first starting the project up using runserver on localhost it advises:

Python:   3.4
Django:   1.8c1

Performing system checks...

System check identified no issues (0 silenced).

You have unapplied migrations; your app may not work properly until they
are applied.
Run 'python manage.py migrate' to apply them.

See below. Not sure where to go from here. Any ideas?

On running manage.py migrate it returns a ProgrammingError as follows:

Hi,

I think you'll have to be more specific, what do you want to do with the
old image? Delete it? Use it again?

Re-run only tests that failed last time

[Gergely Polonkai]

Hello,

I have a pretty extended test suite for my application, which can run for
about 15 minutes. Now when I introduce an error, I will be notified of it
pretty late, and a one-liner fix needs another 15 minutes to check. Of
course if only one of my tests fail, I can add the name of the test case as
a parameter to manage.py test, but in case of many failures it’s pretty
hard to do the same.

Is there a way to run only the tests that failed last time, even if I have
to install a separate app/module for that? A quick Google search gave me no
usable results.

Best,
Gergely

Re: image handling

[Andreas Kuhne]

Hi,

Ok, so what you should do is add a signal to pre save and then delete the
old image if the new image is attached.

Something like this should work:

from django.core.files.storage import default_storage as storage
from django.db.models.signals import pre_save


def image_delete(sender, instance, *args, **kwargs):
  if instance.pk:
old_instance = User.objects.get(pk=instance.pk)

if old_instance.image != instance.image and instance.image:
  storage.delete(old_instance.image.name)

pre_save.connect(image_delete, sender=User)

You can see more information about signals here:
https://docs.djangoproject.com/en/1.7/topics/signals/

Andréas

Re: Image resizing

Hi,

Check out the easy_thumbnails plugin.
http://easy-thumbnails.readthedocs.org/en/2.1/

It automatically resizes all images to the size you want if you use it
correctly.

Re: Re-run only tests that failed last time

[Andreas Kuhne]

If you have created packages for your tests, you can run all tests in a
package. If the tests aren't in the same package, it won't help you however.

Re: Image resizing

[Andreas Kuhne]

You can use Pillow to change the size of the images yourself. That is
however pretty complicated and IMO not really worth the effort. I would go
with easy_thumbnails.

Re: image handling

[Andreas Kuhne]

Hi,

You shouldn't do it in the view, do it in the database model instead. It
won't do anything to any other fields than the image field the way I wrote
the function (all other fields are untouched).

The reason you shouldn't do it in the view, is because if you were to
update the image any other place than via the view, the code wouldn't run.
It's more sensible and more DRY to do it in the model.

Regards,

Andréas

 Hi,

 Ok, so what you should do is add a signal to pre save and then delete
 the old image if the new image is attached.

 Something like this should work:

 from django.core.files.storage import default_storage as storage
 from django.db.models.signals import pre_save


 def image_delete(sender, instance, *args, **kwargs):
   if instance.pk:
 old_instance = User.objects.get(pk=instance.pk)

Only re-running failed tests partly defeats the purpose of testing. Your fix 
for failing test case A may introduce a failure in test case B.

Instead, I would look into either tweaking you very slow test so they run 
faster, or splitting up your test cases into fast and slow tests, so you can 
run your slow tests less frequently depending on some setting.

Erik

Re: image handling

[Andreas Kuhne]

First, make sure that the whitespace is the same in all of your methods (in
python whitespace is significant, which means that you should indent all
files the same amount, I wrote my example in my email, so I only indented
twice, you seem to have 4 blankspaces in your file, so make sure the
indentation is the same).

Secondly, I think that you should add the code I sent to the __init__.py
file in the project itself (in the same directory that you have you
models.py). That way it will be run during startup (which needs to be done).

Andréas

Re: Re-run only tests that failed last time

[Gergely Polonkai]

@Erik: On the CI side, certainly, I will run all the tests upon each
commit. I want to utilize this thing only on my developer machine, so I can
do a quick run after I think I fixed a problem. Naturally, if those failing
tests are green, I will run the whole suite again.

Separating/tweaking my current tests is not really an option; the whole
project is pretty big, with some large apps (yes, those must be cut in
smaller pieces, but that’s not today’s work yet). It will happen, though,
but thanks for pointing it out!

@Ramiro Morales: This juno test runner seems promising, thank you for the
link!

Why is list(Model.objects.all()) 10x slower against an Oracle database as compared to Postgres?

[Daniel Porter]

I have an application that we run locally against a postgres database but 
our dev/test/prod servers all run Oracle.

The command list(Person.objects.all()) runs remarkably faster against my 
local Postgresql database. It takes at least 10x longer against an Oracle 
database. The thing is the query itself doesn't seem to be holding it up. 

I don't really know how to track this down without going and putting random 
print datetimes in the django sourcecode. I'm using django 1.4, and the 
cx_oracle driver to communicate with oracle.

Re: Re-run only tests that failed last time

[Russell Keith-Magee]

Hi Gergely,

One option is to use a test suite GUI tool, like cricket:

http://pybee.org/cricket

Cricket lets you view your entire test suite as a tree, select subsets of
the suite to run, see test results as the suite executes, and re-run the
failures from the previous execution.

Yours,
Russ Magee %-)

Re: Re-run only tests that failed last time

I use py.test [1], another test runner which has plugins that offer this
feature. The pytest-django [2] plugin provides the necessary integration
to make py.test able to run a normal Django test suite. Then the
pytest-cache [3] plugin offers an ``--lf`` (last-failed) option to run
only the tests that failed in the last run, and the pytest-xdist [4]
plugin offers the even-more-advanced ``--looponfail`` option, which "run
your tests repeatedly in a subprocess. After each run py.test waits
until a file in your project changes and then re-runs the previously
failing tests. This is repeated until all tests pass after which again a
full run is performed."

If you're interested in advanced Python testing, I think py.test is near
the top of the list of tools you should at least take for a spin.

how to initiate an interactive python script from an html cgi?

[arthur sherman]

i have a python script which currently runs in a shell cli.
i'd like to initiate this script from a web page.
the closest i got was to have the output displayed on the webpage (w/o 
linefeeds),
but it crashed when requesting input via raw_input().
i simply did 'exec python-script-name' from the cgi.
ok, i now understand why it crashed and why the output is displayed 
primitively
it's  now my understanding that django can help.
where's the best place to start?
tnx
ams
