Anyone using django tabs ?

[tony gair]

I am trying django tabs for my site navigation and was wondering is I have 
to list multiple tabs in the html file thats inherits from base.html

{% if request.user.is_superuser %}
 {% activetab "topnav" "home" %}
 {% activetab "topnav" "admin" %}
{% endif %}

or can I say
{% if request.user.is_superuser %}
 {% activetab "topnav" "home" "topnav" "admin"%}
{% endif %}

or even 

{% if request.user.is_superuser %}
 {% activetab "home"  "admin"%}
{% endif %}

with only one navigation bar?

Re: readonly_fields

[tony gair]

Ah thanks that explains that I'll look into changing the readonly
attribute on the widget, is there a list of widgets do you know as some of
these are choice fields i.e. non text and non integer fields

readonly_fields

[tony gair]

I have tried to use readonly_fields in a form to designate fields that the 
user is not allowed to change.

class Meta 
readonly_fields = [user]
e.g.


However when I show the form the user can edit them.doh, btw I do want 
to display, but not to edit!

Re: database -> model -> charting

[tony gair]

I have subsequently located the problem. I think where the chartit.py 
supplies a parameter saying use_decimal=true is wrong. I have removed that 
parameter and found that it works with that change. 
Do you know if this is because of updates to jquery?

I tried that on 1.5 and tried my code out in a 1.4 install. I get the same 
error.  Interestingly in stack overflow they mention this problem at 
http://stackoverflow.com/questions/8644060/caught-typeerror-while-rendering-init-got-an-unexpected-keyword-argument

and chartit in its own code seems to expect a decimal value regardless, so 
maybe decimal values are hardwired into the code

This was my error. What I did was replace the two american city temperature 
example with my own model data. However my data was different in that the 
two temperatures were integer and the time axis variable was actually 
utctime time (unconverted :) ) , the odd thing though is that there seems 
to be no way to specify the variables going in to the wrapper. e.g. Why is 
it insisting on a decimal, I cannot see where this is specified in the 
example!

After trying this I find a problem with the types it can use. For example 
it does not seem to like BigIntegerField unless there is something else I 
am doing wrong. Thinking about it, maybe I am letting chartit do too much 
for me but I do like the idea of something doing the hard thinking for me 
:). I am using python 2.7 and django 1.5, are you using the same ?

Been trying out a couple over the last few hours. I have to say, the one 
you mention seems streets ahead of anything else, and its documented really 
well, which is the clincher for me.
Many thanks for that super helpful info!

Re: getting information from a many to many model from user

[tony gair]

That would work nicely if I had done my own user management app but I 
lazily used Userena. I think I need to override a function of their profile 
form so it only displays fields if the superuser or a designated boolean in 
same said profile is set to true:)
Do you know how I would over ride a class function ?

getting information from a many to many model from user

[tony gair]

I use the Userena app to manage my users but I want the superuser to choose 
the organisation for them so they cannot wonder around other organisations 
information.

I can either create a foreign key in their profile to point to the 
organisation but then I expect they can change it, which would not be 
acceptable. 

I could create a many to many set of models (as per the documentation) but 
then I need to discover the organisation they are part of, every time a 
form is entered into, in which case I would need a function to discover the 
organisation id from the querying the user object in my group model.

My favourite would probably be to have unmodifiable fields (by them) but 
which the superuser can alter. Anyone know how I would do this?

Re: CBVs and logging a user

[tony gair]

my URLS_CONF points to my urls.py in my main project directory. The error 
only once I press the login button, the form is validated, the user 
then(correctly ) is authenticated then it fails with the error when I try 
to redirect it to a view.

django , python and ides

[tony gair]

Python and Django are not my first languages and currently I am using it 
like I would a compiled language inside gedit on debian wheezy. I was 
actually quite surprised to find a lot of people using it on windows and 
macs when I went to my local python user group but enough digression!.
 I was wondering if anyone using debian wheezy can recommend a nice ide 
(hopefully opensource but if not then relatively inexpenisive) for django 
and python?

CBVs and using existing forms for user authentication etc

[tony gair]

I'm trying to write my first django app using cbv's and good practice ala 2 
scoops!

(thanks for all the help so far in this forum btw!)

I have constructed the app using django braces and CBV's and have noticed 
that I can only authenticate into my app through the admin panel.

I suspect that django already has the logging mechanism for my abstractuser 
and its just a matter of declaring it in my urls, 

is this so?

Re: django 1.5 abstractuser / accessing information of logged on user

[tony gair]

Thanks for the post Tom, I notice that the FormMixin class is from 
django.views.generic.edit and I am confused to how to use it so I gave it a 
try with
#views.py
class PremisesUpdateView(LoginRequiredMixin, FormMixin):
form_class = PremisesForm 
model = Premises
success_url = reverse_lazy('premlv')
def get_form_kwargs(self):
kwargs = super(PremisesUpdateView, self).get_form_kwargs()
kwargs['heating_user'] = self.request.user
return kwargs
#forms.py
class HeatingUserForm ( forms.ModelForm):

def __init__(self, *args, **kwargs):
self.user=kwargs.pop('heating_user')
super(HeatingUserForm, self).__init__(*args, **kwargs)
if self.user.is_superuser:
self.fields['premises'].queryset = Premises.objects.all() 
elif self.user.is_staff:
self.fields['premises'].queryset = 
Premises.objects.filter(organisation=self.user.organisation)
else:
self.fields['premises'].queryset = 
Premises.objects.filter(id=self.user.premises)
 
#premises = CustomModelChoiceField(queryset=Premises.objects.all())
#organisation = CustomModelChoiceField(queryset=Organisation.objects.all())
class Meta:
model=Heating_User
fields = [ 'username', 'password', 'first_name', 'last_name', 
'email', 'is_staff', 'is_active', 'date_joined', 'jobtitle', 
'organisation', 'premises' ]

however a problem now occurs with my urls.py  , because not i get an error 
'type object 'PremisesCreateView' has no attribute 'as_view'
#urls.py
 ),
url(
regex=r'premuv/(?P\d+)/$',
view=PremisesUpdateView.as_view(),

do you know what I would substitute as_view() for ,

thanks for the grounding in these CBV, I am using them ala 2 scoops of

do I need to import anything to access that the value 'user' ?

django 1.5 abstractuser / accessing information of logged on user

[tony gair]

I am using CBV / django braces for authentication. My user authorisation 
model inherits abstractuser and adds a few fields which are foreign keys to 
two other models organisation and premises.

When a form initialises I want to be able to examine the details of the 
user logged in , look to see if they are a is_superuser  or is_staff and 
occupy my organisation and premises form fields accordingly using the 
values stored as foreign keys in the logged on and authenticated user. 

My main problem at the moment is that I get a KeyError for the line 
'self.user=kwargs.pop('user')' centered on 'user'


#heating/forms.py
from django import forms
from .models import Organisation, Premises,  Heating_User, Room, Heater

class HeatingUserForm ( forms.ModelForm):

  def __init__(self, *args, **kwargs):
self.user=kwargs.pop('User')
super(HeatingUserForm, self).__init__(*args, **kwargs)
if self.user.is_superuser:
self.fields['premises'].queryset = Premises.objects.all() 
elif self.user.is_staff:
self.fields['premises'].queryset = 
Premises.objects.filter(organisation=self.user.organisation)
else:
self.fields['premises'].queryset = 
Premises.objects.filter(id=self.user.premises)
 

#models.py
from django.conf import settings
from django.core.urlresolvers import reverse
from django.db import models
from django.contrib.auth.models import AbstractUser

class Heating_User (AbstractUser):
  jobtitle = models.CharField(max_length=255)
  organisation = models.ForeignKey(Organisation, null=True)
  premises = models.ForeignKey(Premises, null= True)
def __unicode__(self):
return self.username
def get_absolute_url(self):
return reverse('users-detail', kwargs={'pk':self.pk})
#end of files

 
can anyone see where I am going wrong here?

Re: linking the logged in user to other models to filter query sets -( noobie )

[tony gair]

I think my first post was a bit messy and I left some information out
I have an organisation as a foreign key contained in my abstact user object 
which is Heating_User. The premises also contains the organisation as a 
foreign key. What I am looking to do on my premises view is to filter the 
premises so that the organisation is the same as that for the logged in 
user. Although my model does include the premises id I want it so there is 
a organisation wide flag that would list all the premises if that flag was 
set. The superuser flag I (oh my that looks really useful). I think you 
have probably told me what I need to know but I'm not sure. I guess what I 
am asking in addition is how do I access the logged in user organisation 
foreign key so that I can filter the query? 

I hope that makes sense, I am quite new to this, but very enthused!!

linking the logged in user to other models to filter query sets -( noobie )

[tony gair]

I've done a basic django app with a user which contains an organisation and 
premises foreign key inside the user model which has been inherited using 
the features of django 1.5.

I use the organisation id and premises id inside other models which I would 
like to present themselves providing they are the same.

I have tried to closely follow the 'two scoops of django approach' in that 
I use a CBV with django braces approach to show my models.

It is very important for me only to show the models in the views which use 
either the organisation id or premises id.

At the moment in my  forms.py for my  user it looks like


#forms.py
class HeatingUserForm ( forms.ModelForm):

premises = CustomModelChoiceField(queryset=Premises.objects.all())
organisation = CustomModelChoiceField(queryset=Organisation.objects.all())
class Meta:
model=Heating_User
fields = [ 'username', 'password', 'first_name', 'last_name', 
'email', 'is_staff', 'is_active', 'date_joined', 'jobtitle', 
'organisation', 'premises' ]

***

Unless the user is a super user, I want the organisation to be restricted 
to the organisation that the logged in user is of the same . The premises 
should be restricted to those premises that have the same id as the logged 
in user. 

Can anyone tell me how this is done?

:)

listing objects in a html file

[tony gair]

This file is used to print out the name of the premises with an update link 
, however I wanted to add a list of premises with the in_use flag set to 
false. 
Can anyone tell me what I am doing wrong?


{% extends "base.html" %}

{% block content %}
Premises

{% unusedpremises = [] %}
{% for premises in object_list %}
{% if premises.in_use %}
{{ premises.name }}  Update   

{% else unusedpremises.add(premises) %}
{% endif %}
{% endfor %}

Unused Premises

{% for premises in unusedpremises %}
{{ premises.name }}  Update  
%nbsp 
{% endif %}
{% endfor %}

{% endblock %}
