Re: [offtopic] put a title

[Ivan Ivanov]

Just a little hint – it woud be good, when you put an informative title
of your emails, so the people can orient what the topic of the email is.

Best wishes!

Use Choice field with image in the option. You do not need FIleField,
couse you don't operate with files at all. You just want to put an
image in a select.

There are several ways to achieve this:
background image (pure html+css)

Jquery UI;
or something like this:

Use static files for that:

Why don't you use static files?

Re: howto disable label for field in admin app form?

[Ivan Ivanov]

Source:
https://docs.djangoproject.com/en/dev/ref/forms/api/#configuring-html-label-tags
If auto_id is False, then the form output will not include  tags
nor id attributes:
f = ContactForm(auto_id=False)

I think, this is exactly what you want.

Django-CMS and inherit plugin

[Ivan Ivanov]

Hi all!

It's a silly question, but I cannot get it.
What does this mean:
„The inherit plugin is currently the only core-plugin which can not be
used in non-cms placeholders.“
This is taken from the Django-CMS documentation:
http://docs.django-cms.org/en/2.2/getting_started/plugin_reference.html#inherit

The plugin is properly installed and I can add it from the admin, but
when I try to see the public page with my basic template, I've made
with the tutorial, I become the following error:

Caught AttributeError while rendering: 'NoneType' object has no
attribute 'render_plugin'

The problem is in the template on the following line:
{% placeholder "template_1_content" %} 

I know, that this has something to do with the sentence from the docs,
I cannot understand, but I am stuck...

Thanks for the help!

Ivan

Re: mysql installation error

[Ivan Ivanov]

First – It's not a Django question,

and second search, read, but try:
http://www.fuyun.org/2009/12/install-mysql-for-python-on-windows/

That was the second result I found :)

I hope, it is what you need, couse I don't use windows and cannot test
the problem and its solution.

Extending admin's index view

[Ivan Ivanov]

Hallo everybody!

I've got problem exteding the admin's index view. I need to pass
extra_context to the index of the admin, after the administrator logged
in, that's why I'm trying to extend the view. So...

What I've got is:

In the root of the project I modified urls.py like following:
   (r'^admin/$', project.admin.admin_site.index),
   (r'^admin/', include(admin.site.urls)),

Again in the root of the project I've got admin.py with the following
snippet of code:

[...]
class AdminSiteRegistryFix( object ):
'''
This fix links the '_registry' property to the orginal AdminSites
'_registry' property. This is necessary, because of the character of
the admins 'autodiscover' function. Otherwise the admin site will
say, that you havn't permission to edit anything.
'''

def _registry_getter(self):
return default_site._registry

def _registry_setter(self,value):
default_site._registry = value

_registry = property(_registry_getter, _registry_setter)


class MyAdmin(sites.AdminSite, AdminSiteRegistryFix):
@never_cache
def index(self, request, extra_context={}):
last_report_date = models.Reports.objects.latest().entry_date
now = datetime.now() 
delta = now - last_report_date
extra_context['last_report_interval'] = delta.days

return super(MyAdmin, self).index(request, extra_context)

admin_site = MyAdmin()


And it works. I've got the last_report_interval in the index.html
template and I can write my lovely message to the admin. The problem
is, that the ^admin/$ address swiches between the login and index view,
despite of users authentication status. And this is nice, but not
working after my changes, written above. Now I see only the app list of
the index. When I'm not logged in, I just see an empty list, but I've
got no login form...

Can anyone help me, understanding why has my login form disappeared?

What I can see from the django.contrib.admin.sites is that the
admin_view function is the one, calling the login view. But I have
noting to do with it, I haven't modify it and I don't understand what
disturbs it's functionallity.

Thank you in advance for your help!

Ivan Ivanov
