Hi folks!!!
Many of you have faced the same problem for creating an alias of the frequently used command .
But here is another way to do it . It is not just to add alias using alias command which will enable the particular alias for particular session and console . I am not going to use alias command to create aliases .
I would suggest you (if you do not have root access ) to write a script which will help you to use it like an alias .
For example suppose you want to create the alias for telnet command , for root user it is easy to create , by adding a single line to .bashrc file but for a non-root user this is very handy .
-===========
vi t ### create a filename with t name
####add the following line to this file
telnet $1 $2
###save and quit :wq
chmod 777 t
now use the following command
./t yourdomain.com 25
#### voila it is working
Now it depends on you to choose it or reject it .
In the same way you can create many script for your aliases.

Here, i am writing all the possible customize admin function.
If a user belong to a specific city then he/she could add the events for that city except othersclass
EventAdmin(admin.ModelAdmin):
model = events
# Attributes
list_display = (‘title’, ‘event_type’,'city’,'join_name’)
list_display_links = (‘title’, ‘event_type’,'city’)
list_filter = ['title','event_type','city','sites']
list_select_related = True
search_fields = ['title']
save_on_top = True
raw_id_fields = (‘event_type’,'city’)
list_per_page = 2
prepopulated_fields = {‘title’: (’summary’,'description’)}
fieldsets = (
(‘Add Event’, {‘fields’: (‘title’,'event_type’,'city’,'visibility’,'highlighted’,’sites’), ‘classes’: (‘wide’,)}),
(‘Additional Information’, {‘fields’ (’summary’,'description’,’start_date’,'end_date’,’start_Time’,'end_Time’,'admission’), ‘classes’: (‘collapse’, ‘wide’)}),
(‘Address Information’, {‘fields’: (‘contact_detail’,'booking_url’,'venue’,'address’,'phone’,'mobile’,'image’,'image_caption’), ‘classes’: (‘collapse’, ‘wide’)}),
)
#A cool thing there is the ’site_list’ column. By default, we can’t use a ManyToManyField
def site_list(self):
if self.sites:
sites = [site.name for site in self.sites.all()]
string = “, “.join(sites)
return string
# To give the edit permission city wise
def has_change_permission(self, request, obj=None):
#if obj and request.user.groups.name == ‘Chicago’:
#city=request.user.get_profile().res_city
if obj:
return obj.city == request.user.get_profile().res_city
return super(EventAdmin, self).has_change_permission(request, obj)
# To give the add permission city wise
def has_add_permission(self, request):
#if obj and request.user.groups.name == ‘Chicago’:
#city=request.user.get_profile().res_city
if request.user.get_profile().res_city:
return super(EventAdmin, self).has_add_permission(request)
# To return the records city wise
def queryset(self, request):
#return self.model._default_manager.filter(city=’Chicago’)
return self.model._default_manager.filter(city=request.user.get_profile().res_city)( OR )
def queryset(self, request):
qs = super(EventAdmin, self).queryset(request)
if request.user.is_superuser:
qs = qs.filter(city=request.user.get_profile().res_city)
return qs
#return self.model._default_manager.filter(city=request.user.get_profile().res_city)
admin.site.register(events,EventAdmin)
