Re: How to clean a model after the related models inline forms have been saved?

[Andy]

Please forget about the persisting data part. 
The problem is that inside the parent form i dont have access to the 
related data and the formsets new related data is validated after the 
parent models data.
Inside the formset every related data model does not have access to the 
other related instances.

I want to have additional validation after all data on the admin page has 
been processed .. not necessarily saved into the database, but i need some 
way of doing additional validation after the basic stuff has been taken 
care of by the admin and its form.

I still don't understand why you want to persist unvalidated data to the db 
then?  if a user requests the data in mid-update, that's something that can 
be handled with transaction locks on the db.  so when that happens, the 
request will wait till the locks are released before executing the db query

No i dont want to return anything but a possible validation error based on 
all related objects new data. 
I probably see myself rewriting the changeform_view and manually adding the 
error the the forms non field errors, unless somebody comes up with a more 
clever idea.

Well, i dont necessarily have to, but i somehow need to be able to perform 
a query with all updated data taken into account. The easiest solution i 
came up with is putting everything into the DB while in transaction so i 
could perform my queries and rollback if the checks dont work out. 

Im open to any other ideas.
And is there a prepared admin function that is suitable for validation 
logic after related objects are validated?
I might also just write some validation data to the parent while executing 
the formet validation and so i could verify my parent validation against 
this extra data even without additional queries against the DB.

So far i just see that the changeform_view handles object and formset 
validation without any way of interfering (other than rewriting that view 
logic).

Re: how to manage range of hours in models and forms in django1.4

[Sunny Nanda]

One way to store such information can be like this:
Create a model "Day". This will hold entries for each day i.e. from Monday 
till Sunday
In the UserProfile model, create a ManyToMany relation to the above defined 
Day model through an intermediate table (say WorkingHours) which can hold 
the "from" and "to" time.

Partial example below:

class UserProfile(models.Model):
> working_hours = models.ManyToManyField("Day", through="WorkingHours")
>
> class WorkingHours(models.Model)
> profile = models.ForeignKey("UserProfile")
> day = models.ForeignKey("Day")
> from_time = models.**TimeField()
> to_time = models.**TimeField()
>

While creating the forms, take input from the user for the WorkingHours 
model. This way, the days of work will not be hardcoded, and user can 
select mutiple choices.

Sandeep

I would create an extra Model which defines these opening times:

class OpeningTimes(models.Model):
day = models.CharField(max_length=10)
start = models.DateTimeField()
end = models.DateTimeField()

and define a manytomany relation ship from the UserProfile to your 
OpeningTimes model.


I've opted for the DateTimeField here, there's no Time Field in django 
by default. But you could just use any date (maybe use some kind of 
default date or use the current date)
and make sure the time has been filled in correctly. And then just 
extract the right hour from the DateTime field.

Jonas;

Untested, but I'd try this:
class DaysOfWeek(models.Model) :
name = models.CharField(max_length=32)

class BusinessHours(models.Model) :
day = models.ForeignKey(DaysOfWeek)
start = models.TimeField()
end = models.TimeField()

class Institute(models.Model) :
   # ...
   business_hours = models.ManyToManyField(BusinessHours)

Not sure if the Admin handles this ok though. An alternative:
class DaysOfWeek(models.Model) :
name = models.CharField(max_length=32)

def __iter__(self) :
return self

def next(self) :
for entry in DaysOfWeek.objects.all() :
 return (entry.id, entry.name)

class BusinessHours(models.Model) :
day = models.CharField(max_length=32, choices=DaysOfWeek)
start = models.TimeField()
end = models.TimeField()

Re: how to manage range of hours in models and forms in django1.4

[Jon Black]

If the days have to be hardcoded (I imagine you have a row/field
for each day), then you could use a hardcoded string for the day
(not editable nor related to your model), and provide two Time
fields. Using Time gives you advantages:

* You can use python's DateTime module to calculate the hours
* You can more easily use a funky date/time style widget if you
ever need it
* You will avoid making mistakes trying to calculate the hours
manually
* You can validate the form data using python's date/time module

If you're really open to suggestions (just thinking outside the
box, and possible outside of the scope), but you could use a
separate table to record all hours recorded rather than just
counting the hours as they're entered.

  Now the text Moday(weekdays can be hardcoded but i personally

  Now if you see this is a simple CharField where the user

  So i want to know what type of model field should i create
  CharField or Time Field.
  If i   go for CharField it will simply save the details like
  0900-1800. So if i need to know how many hours that particular
  person is available for work then how will subtract that from
  CharField.
  So i need help to know what exactly the field i should create
  such that it satisfies the template look and backened queries
  also.

I understand that institue_hours_of_operation is a count of the

just need to count the hours with each form submition and add

that logic in a few places. In class-based views, I tend to put
it in form_valid().

Apologies if I've misunderstood :)

Re: how to manage range of hours in models and forms in django1.4

[Nikhil Verma]

Hi Jon

Yes it is the count of the hours.They will enter in the following manner "-

Monday : 0900-1800, Tuesday and so on ... This will be entered by the user
who is filling the form.

Now the text Moday(weekdays can be hardcoded but i personally don't want.)
Now if you see this is a simple CharField where the user enters details for
the number_of_hours.
So i want to know what type of model field should i create CharField or
Time Field.

If i   go for CharField it will simply save the details like 0900-1800. So
if i need to know how many hours that particular person is available for
work then how will subtract that from CharField.

So i need help to know what exactly the field i should create such that it
satisfies the template look and backened queries also.

Re: how to manage range of hours in models and forms in django1.4

[Jon Black]

I understand that institue_hours_of_operation is a count of the
hours the user has worked, is that correct? If so, I suppose you
just need to count the hours with each form submition and add
that to the current institue_hours_of_operation value. You can do
that logic in a few places. In class-based views, I tend to put
it in form_valid().

Apologies if I've misunderstood :)

how to manage range of hours in models and forms in django1.4

[Nikhil Verma]

Hi

I am developing an event app which has users who publish events , other
users also.
Now users have their profile info for which i have made a very common
UserProfile Model with all the necessary details in it.

I have a requirement where in UserProfile model i need to display a field
institue_hours_of_operation( no. of hours that an institute works)


class UserProfile(models.Model):
user = models.ForeignKey(User, blank=True, null=True, unique=True)
first_name = models.CharField(max_length=30, blank=True)
last_name = models.CharField(max_length=30, blank=True)
gender = models.CharField(max_length=1, choices=GENDER_CHOICES,
blank=True)
birth_date = models.DateField(auto_now_add=True)

zip_code = models.IntegerField(max_length=7, blank=True, null=True)

   and so on

# Note the weekdays like monday,  tuesday they are all hardcoded as
requirement but i don't want that to be hardcoded.
Also i am using a django forms  to display this.


How can i design this form field as well in models or What should be the
type of this field both in models and forms such that weekdays remain
dynamic(i can simply generate them from loop) and the user can fill the
time  and when he hits submit it will get saved.

Two views, Two models, Two forms, one template

[Jonathan]

I am sure this is some very easy and simple concept I am just not
grasping.  I have two views which are very similar.  Both take the
same variable and iterate the applicable data.  I am trying to get
them to render on the same template.  However, when I create one as a
template tag and try to pass the common variable, I get variable is
not defined errors.

def projectfilesindex(request, object_id):
def store()
...
files = ProjectFileUrl.objects.filter
(project_number=object_id).order_by('-uploaded')
if not request.method == "POST":
form = UploadForm()
return render_to_response(
'projects/files.html',
{"form": form, "files": files},
context_instance = RequestContext(request, object_id)
)

form = UploadForm(request.POST, request.FILES)
if not form.is_valid():
return render_to_response(
'projects/files.html',
{"form": form, "files": files},
context_instance = RequestContext(request, object_id)
)

file = request.FILES["file"]
filename = file.name
content = file.read()
store(...)
p = Project.objects.get(pk=object_id)
f = ProjectFileUrl(url="http://someurl.com/; + object_id + "_" +
filename,
name=object_id + "_" + filename, project_number=p)
f.save()
files = ProjectFileUrl.objects.filter
(project_number=object_id).order_by('-uploaded')
return render_to_response(
'projects/files.html',
{"form": form, "files": files},
context_instance = RequestContext(request, object_id)
)

def announce(request, object_id):
announcements = ProjectAnnouncement.objects.filter
(project=object_id).order_by('-date_posted')
if not request.method == "POST":
form = ProjectAnnouncementForm()
return render_to_response(
'projects/announcement.html',
{"form": form, "announcements": announcements},
context_instance = RequestContext(request)
)
form = ProjectAnnouncementForm(request.POST)
if not form.is_valid():
return render_to_response(
'projects/files.html',
{"form": form, "announcements": announcements},
context_instance = RequestContext(request)
)
title = request.POST['title']
body = request.POST['body']
d = datetime.now()
p = Project.objects.get(pk=object_id)
a = ProjectAnnouncement(author_user=request.user, date_posted=d,
project=p, title=title, body=body)
a.save()
announcements = ProjectAnnouncement.objects.filter
(project=object_id).order_by('-date_posted')
return render_to_response(
'projects/announcement.html',
{"form": form, "announcements": announcements},
context_instance = RequestContext(request)
)


As they both stand, they work separately.  Every time I try and
combine them, or make one a template tag, I end up with an error, or
only getting one to work and the other fails silently.  When I try and
make one into a template tag, I end up with the "object_id" is not
globally defined error.

I'm sure I am missing something really basic.  Does anyone have a
pointer to get me going in the right direction?

That's only in the SVN version, but if we have to move from .96 to SVN to
