jazzband / django-constance Goto Github PK

right now, if you create a config key as a list, the constance admin ui is unable to help and will blow up.

looking at the code, this should be a simple fix.

Pypy version of django-constance is 0.6. Can you update it?

The error it gives is the one in #64.

Hi,

Thanks for a great app to work with live settings.

I have a weird problem where there seems to be a mismatch in the admin form between the settings and their default values as retrieved from settings.py and the values from the database. Some of the values from the database do not appear in the correct fields, for example I have the following settings in settings.py:

business_name -> default value: "My Business", value in form: "09980 122112"
business_phone -> default value: "09980 122112" value in form: "My Business"

So, the phone number and business name have somehow been switched.

For some reason constance seems to mix up settings and values. Any idea? Thanks.

Given that we can now store lists in constance (thanks #54), we now ought to improve support for lists as keys in constance.

Specifically, we ought to either:

• document proper use of defining and using lists as keys
• improve constance handling of lists to simplify use of lists in constance

As an example, lists come out as unicode strings and need something like eval():

>>> from constance import config
>>> config.EMAIL
u"['[email protected]',]"
>>> email = eval(config.EMAIL)
>>> email
['[email protected]']

How should this be addressed?

Hi all,

Love constance, and I've been using on my projects for a while now. I've been playing around with the dev version of Django (1.8a1/1.8b1), and noticed a change in the ContentTypes Model that breaks Constance on manage.py migrate.

https://docs.djangoproject.com/en/1.8/ref/contrib/contenttypes/
name
The human-readable name of the content type. This is taken from the verbose_name attribute of the model.
Changed in Django 1.8:
Before Django 1.8, the name property was a real field on the ContentType model.

In particular, the error is

File "/lib/python2.7/site-packages/django/db/models/sql/query.py", line 1369, in names_to_path
    "Choices are: %s" % (name, ", ".join(available)))
django.core.exceptions.FieldError: Cannot resolve keyword 'name' into field. Choices are: app_label, id, logentry, model, permission

from

File "/lib/python2.7/site-packages/constance/models.py", line 16, in create_perm
    model='config')

I was able to hack around it simply by removing the name='config' line from constance/models.py
Thanks for all the hard work!

Cheers,
Jonathan

I tried constance with Django 1.3 but I am getting --- Meta' object has no attribute 'abstract' --- , when viewing pages after installation. Looking at your admin.py file in the class Config(), I am not seeing any abstract being defined. Does constance support 1.3 at all?

Hello!

Do you can maintain django-grappelli support for django-constance? Somebody should overwrite default django-grappelli templates for django-constance, because django-grappelli don't have support for "version" field in django-grappelli/grappelli/templates/admin/constance/change_list.html.

Greetings,
Adam Dobrawy

I think you forgot the quotes around the CONSTANCE_BACKEND property value in your documentation. It should be set like this:
CONSTANCE_BACKEND = 'constance.backends.database.DatabaseBackend'

Under Database.

CONSTANCE_BACKEND = constance.backends.database.DatabaseBackend

Should be:

CONSTANCE_BACKEND = 'constance.backends.database.DatabaseBackend '

Django version 1.6.x:

AttributeError: 'Meta' object has no attribute 'object_name'

Raised when accessing the /admin/ index.

It would be great to allow line breaks in the help text of the various config options. E.g.:

CONSTANCE_CONFIG = {
    'MY_SETTING': ('foo', 'This is some help text\n\nWith line breaks!')
}

I just happened to notice and thought you might want to know.

I have updated some of the translations, and (I think) they are better than current ones. Please consider pull translation files from Transifex :)

What did you think about overriding default field and widgets from FIELD.
I think that adding some custom widgets, like forms.widget.Select, it's a good idea.

For back capailty i want to add separate settings FIELD_OVERRIDE.
It will be something like this.

CONSTANCE_CONFIG = {
    'MY_SETTINGS_KEY': (42, 'the answer to everything'),
}

FIELD_OVERRIDE = {
    'MY_SETTINGS_KEY': (fields.ChoiceField,
                        {
                            'widget': forms.Select,
                            'choices': ((42, 'it is'),
                                        (37, 'not so good'))
                        })
}

What did you think about it ?
If you agreed with me that it's quit usefull i will implement it and create a pull requst.

I just followed the readme :
added picklefield, constance, constance.database.backend, in this order, but the app still wants the redis-py component install to start :

File "snip/site-packages/constance/init.py", line 3, in
config = Config()
File "snip/site-packages/constance/config.py", line 9, in init
utils.import_module_attr(settings.BACKEND)())
File "snip/site-packages/constance/backends/redisd.py", line 27, in init
"The Redis backend requires redis-py to be installed.")
django.core.exceptions.ImproperlyConfigured:
The Redis backend requires redis-py to be installed.

If I install redis-py to overcome the warning, I then get :
ConnectionError: Error 61 connecting localhost:6379. Connection refused.

So at this moment, classic database backend is not possible it seems

If trying to save a datetime type setting getting this in Django 1.5.4:

TypeError
Exception Value:

Dear developers, I looked upon code, there isn't a proper documentation about using. Installing is quite easy but using is harsh (for example which models does constance support). This also implies #38 .

The current stable version of django-constance does not work out of the box on Django 1.6, which has now been released. The following exception is raised when viewing /admin:

AttributeError at /admin/
'Meta' object has no attribute 'object_name'

Now, this has been fixed with the following commit: 987e13f. However, this commit was merged three months ago and the latest django-constance release (0.6) was released eight months ago.

This forces users to install directly from Git if they are using Django 1.6. Instead, it would be great to see a new release of django-constance with the fix included.

I'll be happy to submit a pull request if I can figure this out, as someone else might have similar issues.

I'm trying to update my tests for code that used to make use of static settings in my settings.py file, now that I have switched to using constance.

Previously:

# settings.py
...
MY_SETTING = ''

# models.py
from django.conf import settings

def foo():
    if settings.MY_SETTING == 'VALUE':
        return 'foo'
    return 'bar'

# tests.py
import unittest
from django.conf import settings
from .models import foo

class MyTest(unittest.TestCase):
    def test_foo(self):
        settings.MY_SETTING = 'VALUE'
        self.assertEqual(foo(), 'foo')

And then for all my tests I could try setting settings.MY_SETTING appropriately and test the response:

Creating test database for alias 'default'...
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK
Destroying test database for alias 'default'...

I tried converting this converted this to:

# settings.py
...
INSTALLED_APPS += ('constance',)
CONSTANCE_BACKEND = 'constance.backends.database.DatabaseBackend'
CONSTANCE_CONFIG = {
    'MY_SETTING': ('', ''),
}


# models.py
import constance

def foo():
    if constance.config.MY_SETTING == 'VALUE':
        return 'foo'
    return 'bar'

And attempted to test it by setting the value directly:

# tests.py
import unittest
from . import models

class MyTest(unittest.TestCase):
    def test_foo(self):
        models.constance.config.MY_SETTING = ('VALUE', '')
        self.assertEqual(models.foo(), 'foo')

Which returns:

Any thoughts? This seems like it is related to #84? And maybe similar (ish) to #77?

I suggest to provide some info in README or wherever you might think it should be about supported value types and their cast logic for both Redis and Database backends with screenshots of admin site.

For example:
I need to store/retrieve/edit tuple of strings in certain key, but how it will looks like in admin site? as value, value,… or (u'value', u'value',…)?

Thanks in advance for your reply.

is it possible to override a variable in settings.py with a constance value?
My use case is that I want to be able to set DEBUG = True or Debug = False in the constance admin panel.
Also I would like to be able to configure MANDRILL_API_KEY from https://github.com/brack3t/Djrill with a constance variable.

I have been unsuccessful in getting this to work, because constance appears to import from settings.py and when I put 'from constance import config' therefore there is a circular import in my settings.py file.

follow the link:
django-rq support for django-redis
it is a very good feature to configure similar apps the same way

Hello,

Can you help me with this issue?

For example if you need to validate a range in a setting, we should be able to add a validation before the setting is saved.

@jezdez what do you think?

When I go to /admin/constance it gives 500 error:

Hi,

During usage of django-constance in our project I realized db backend uses db_cache as a global and causes gevent to attempt reading wrong values when project is run as threaded. Both tested with gunicorn + gevent and eventlet. Here is the error:

This socket is already used by another greenlet: <bound method Waiter.switch of <gevent.hub.Waiter object at 0x57536e0>>
constance/backends/database/init.py ? in get (application)
value = db_cache.get(key)

Which leeds to read wrong values and crashes the view.

Solution:
I have moved db_cache variable under DatabaseBackend class and moved its initializations under class init. Renamed all db_cached to self.db_cached and so on. This helped to create connection each time a constance wanted, which is inefficient but solved the errors. Didn't send pull request as I use fairly old version of django-constance but I see code in the repo still contains the same error.

Thanks

Update: that didn't actually solved the problem, so thinking on creating a test for gevent

I'm gettting the following traceback when starting runserver on Django 1.7rc2.

I am not entirely sure wether it is an actual bug or I misused your app:

After installing and configuring constance to use the database, django told me that the attribute _prefix did not exist. After looking a bit into the code I added

self._prefix=settings.DATABASE_PREFIX

to DatabaseBackend.init . Now it works.

I'd like to turn off a feature (by unsetting a constance value in redis)

I'm doing it from node.js.

It seems constance uses python pickle's dump to store truth value.
Isn't the dumped value supposed to change as pickle changes with python version?

How should I toggle truth values from outside of python world?

I'm setting I00\n. for False value. Does this look ok?

In change_list template this tag is using, so admin layout is not showing correctly.

I have modified Constance template to work with Grappelli 2.4.0 stylesheet. It could be useful for somebody else. Though I don't know what would be the best approach for sharing it.

This Error occurs when /admin/constance/config/ is called.
With 0b05471 and django 1.7b4

Exception Type: AttributeError
Exception Value: 'module' object has no attribute '_backend'

Can you please enable it?

Can you add a privilege to track the previous config changes???

Hi all,

for usability reasons, it would be nice to be able to add a verbose name (that could then also be translatable) and a group name for display as part of a fieldset.

Just stumbled across this library today, this is exactly what I went in search of, thanks for releasing this.

I'm stilling getting ramped up so apologies if this was covered, but I couldn't find it. I see you support different data types, and render accordingly in the Admin (awesome!!). I was hoping to setup on of my configuration options as a choice, allowing someone to pick one value from a list of choices (as opposed to a text box where they might typo it). Is this possible? If not no biggie, I can work around it, but would be awesome if it was there already.

Thanks

I know there was a rejected support request for this ... but what about a different approach?

I need to change things like EMAIL_SUBJECT_PREFIX, GRAPPELLI_ADMIN_TITLE ... can we not extend django.conf to use the settings.py as a default but load/replace the custom value from Constance at runtime?

When I try to install django-constance use
pip install django-constance or pip install -e git+git://github.com/comoga/django-constance#egg=django-constance
ог use git clone and python setup.py install,
I see the same install error

I often have settings like company_logo that are images. They match the constance work flow perfectly except there is no admin user way to add a custom image. It would need to

• Use django admin image widget
• Not break non database backends (not sure if that would really be an issue or not)
• Would need to have a way to use defaults. How would the default be included in the project. Commit /media maybe? Alternatively we could say no out of box default image support and suggest developers assume '' means use the default.

Alternatives:

• normal settings.py (not end user customization nor multi tenant)
• Custom django model for images (then why use constance in the first place)
• Paste in a url to the image in constance (Not possible to upload the image with just django admin)

This changeset:

https://code.djangoproject.com/changeset/16857

changed the way in which models are registered with the admin in a way that breaks django-constance

It seems to be that this approach of spoofing a model:
https://github.com/comoga/django-constance/blob/master/constance/admin.py#L115

Is no longer effective at injecting a ModelAdmin without a model

This results in a NoReverseMatch error:

http://dpaste.com/646934/

If constance is required as part of a setuptools-distributed package then it will be installed as an egg, which means you'll need to enable the non-default django.template.loaders.eggs.Loader to get the admin to properly load its templates.

Similar issue on another project: ouhouhsami/django-progressbarupload#4

How can I change only one value and let the other keys keep their default value ?

I have found in django admin, when you save constance of project, I have all time form.is_valid() is False. Although I check function clean_version it's not call, I think problem when start init fields in __init__ method, with different types, and there is error, when we call form.is_valid(). I think need review all form fields and check it. My problem happens when I have only int type in CONSTANCE_CONFIG dictionary.

Hi there

I tried using django-constance on a fresh Django (1.2.5) project with redis (2.2.2) and redispy (2.2.2) and i get following error:

http://dpaste.com/489125/

Am I missing something ?

Because
Now code from constance import config sometimes imports constance/config.py insteda of config object because of django registry code init apps in alphabetical order:

# django/apps/registry.py:105
...
# Load models.
for app_config in self.app_configs.values():
    all_models = self.all_models[app_config.label]
    app_config.import_models(all_models)
...

So constance is being inited config after import in apps thats inited before.

Temporary solution is to use constance like:

import constance
...

print constance.config.some_var

Investigating now. If I break where it errors I'm able to run this to make it work

from django.utils.functional import SimpleLazyObject
from constance import Config
config = SimpleLazyObject(Config)

Here is the stacktrace

Are you accepting pull requests anymore? It looks like you have 2 requests that every other fork is having to implement.

• Django 1.4 compat
• Allow empty textfields

Could you accept these or mention why they arent acceptable so we can alleviate the need for all these forks?

Have a good one, thanks man!

I need to store a list of keys which i can change dynamically, but i guess constance doesn't support storing list/tuple objects. any workaround
