Re: Django LMS

[Andréas Kühne]

Hi Suresh,

SCORM is a huge standard and to implement it yourself, you would need to
read the SCORM documentation. You can find this here:
https://scorm.com/scorm-explained/technical-scorm/scorm-12-overview-for-developers/

I don't think how to implement a LMS for SCORM is really a subject that can
be discussed here :-) (it's way too big).

However to implement SCORM in django I would go around it a bit
differently. Implementing the SCORM communication yourself isn't really
that easy - however you can integrate with Scorm Cloud for example. Then
all you need to do is store your delegates and scorm packages in a way that
they can communicate with Scorm Cloud.

Either that or check through OpenEDX.

Regards,

Andréas

Iterate over objects in HTML template doesn't work well

[valentin jungbluth]

I would like to get your help in order to display objects choosen by user 
and get some querysets according to each object.

I'm working with django 1.11.16 on this project.

*Context :*

User has to choice some things :

 - Start date 
 - End date
 - One or several publication(s)

Then, it returns a table with some querysets applied to this/these 
publication(s) and display one publication per row with associated data.

*Forms.py file :*

   
 class PublicationStatForm(forms.Form):
publication_list = forms.ModelMultipleChoiceField(queryset=
Publication.objects.all().order_by('pub_id'))

# This part doesn't work while it should be

# publication_list = forms.ModelMultipleChoiceField(
# queryset=Publication.objects.all().order_by('pub_id'),
# label=_('Publication Choice'),
# widget=ModelSelect2MultipleWidget(
# model=Publication,
# queryset=Publication.objects.all().order_by('pub_id'),
# search_fields=['pub_id__icontains', 'title__icontains'],
# )
# )

def __init__(self, *args, **kwargs):
super(PublicationStatForm, self).__init__(*args, **kwargs)


In this part, I have a ModelMultipleChoiceField because user can select one 
or several publication(s). The commented part doesn't work while it should 
do the job.

*Views.py file :*

In this part, I create some querysets in order to get informations about 
selected publication(s) over a selected time period. I will show you only 
2-3 querysets but it counts 6 querysets.

I pick up the list of publications, get the id and I make a loop over each 
id in the list.

   
 class StatsView(TemplateView):
""" Create statistics pageview """
template_name = 'freepub/stats.html'
form_class = PublicationStatForm

def get_context_data(self, **kwargs):
subtitle = _("Statistics")
context_data = super(StatsView, self).get_context_data(**kwargs)
context_data['form'] = self.form_class()

if "start_date" and "end_date" in self.request.GET:
start_date = self.request.GET.get('start_date')
end_date = self.request.GET.get('end_date')


if start_date < end_date and "SearchPublicationPeriod" in 
self.request.GET:
publication_list = self.request.GET.getlist(
'publication_list')

publication_selected = Publication.objects.filter(id__in
=publication_list)

download_all_period = Download.objects.values('usage', 
'doc__publication__pub_id').filter(
doc__publication__id__in=publication_list).
filter(
Q(creation_date__gte=start_date) & Q(
creation_date__lte=end_date)).aggregate(
nusage=Sum('usage'))

... # create others querysets


publication_overall = zip(publication_selected, 
download_all_period, ...)


context_data['start_date'] = start_date
context_data['end_date'] = end_date
context_data['publication_list'] = publication_list
context_data['publication_selected'] = 
publication_selected
context_data['download_all_period'] = 
download_all_period
...


return context_data


*HTML Template file :*

In this file, I display the form and the result in a table with each row 
according to each publication.

   
 
  

  {% trans 'Publication 
statistics during period' %}
  
  

  

  


  

  

  
  

  


  
  
  

  
  
{{ form.publication_list|as_crispy_field }}
  


  

  

  Request over period : {{ 
start_date|date:"Y/m/d" }} to {{ end_date|date:"Y/m/d" }}



  {% trans 'Period' %}
  {% trans 'Publication' %}
  {% trans 'Downloads/Requests' %}
  {% trans 'Best country' %}
  {% trans 'Best format' %}
  {% trans 'Best customer' %}


{% for publication_selected, download_all_period, 
request_all_period, best_country_period, best_format_period, 
best_customer_period in publication_overall %}
  {% if download_all_period %}

  {{ start_date|date:"Y/m/d" }} to {{ 
end_date|date:"Y/m

RE: function get_form_kwargs() not being called

[Matthew Pava]

Fascinating.  It looks normal, though login_url is not a member of CreateView.
Do you perhaps have another class defined with the same name?
Especially since you do have other class-based views, you must know what you’re 
doing.

Subject: Re: function get_form_kwargs() not being called

I identified that a more efficient way of doing this would be to call the get 
initial method but for some reason it doesn't seem to trigger the function that 
I'm trying to overriede.

class NoteCreate(CreateView):
login_url = 'login'
model = Note
form_class = NoteForm
success_url = reverse_lazy('file_status:list')

def get_initial(self):
print(self.kwargs['file_id'])
print('in get initial')
initial = super(NoteCreate, self).get_initial()
initial['file'] = 2
return initial

Please help me understand. this is really getting frustrating:(

For this one, the text in get initial does not get printed.

What works though is when I don't use Class based view. But I still would like 
to make it work using class based views since my other views are class based.

get_form_kwargs function of my CreateView but when I try to do operations from 
that function, I'm not able to get any result. I tried to do a print but the

class NoteCreate(LoginRequiredMixin, CreateView):

kwargs = super(NoteCreate, self).get_form_kwargs()

kwargs.update({'file_id' : self.kwargs['file_id']})

return kwargs

the print statement doesn't seem to be working. It does not show anything in 
the console.

I'm able to render the form with no errors in the console.

ModelMultipleChoiceField doesn't display objects

[valentin jungbluth]

Hello guys,

I would like to use *ModelMultipleChoiceField* with 
*ModelSelect2MultipleWidget* in order to display a dropdown list with my 
widget.

If I write this :


publication_list = forms.ModelMultipleChoiceField(queryset=Publication.
objects.all().order_by('pub_id'))


It displays my queryset` but the design is not good and if I want to select 
multiple objects, I have to highlight them. Then, I don't have search bar.

[image: search.png]


That's why I would like to write this :


publication_list = forms.ModelMultipleChoiceField(
queryset=Publication.objects.all().order_by('pub_id'),
label=_('Publication Choice'),
widget=ModelSelect2MultipleWidget(
model=Publication,
queryset=Publication.objects.all().order_by('pub_id'),
search_fields=['pub_id__icontains', 'title__icontains'],
)
)



But with this code, this is the result :

[image: search2.png]


It doesn't work and I would like to understand why ?

The expected result should be something like that :

[image: expected.png]

Thank you by advance

I don't use my form to ModelAdmin part, so to my mind it shouldn't solve my

SITE_ID or no SITE_ID, that is the question.

[Ira Abbott]

Whether tis nobler to run separate processes or to handle all in one ...

Unfortunately, I want to use packages that work both ways, and have not 
found a suitable workaround other than picking one style, whacking it up to 
make it play nice and dumping the whole thing in my app directory. 
 Depending the package and approach (derivation versus replacement) this 
can also involve porting data.

My current dilemma involves mixing allauth (oath) (supports 
site_by_request) and dbtemplates (requires SITE_ID).

Is there an 'accepted practice for handling this situation?

Certainly 'request_by_site' works when you set the site ID, but you loose 
the 'site_by_request' behaviour (you always get SITE_ID), so the only 
current 'no hack' solution is to down-shift to SITE_ID if ANY package needs 
it, correct?

As for overlaying (modifying) pip packages, what is the generally accepted 
workflow?  Python finds it if I copy / fork to my app directory. Then, I 
guess, it is a matter of managing the git end of things by forking to the 
app directory.  This will get interesting, as currently my upstream git is 
CodeCommit, and I need the pull of that to CodePipeline to create something 
that works ... but I digress.

Any pointers or other war stories are welcome.

Here is a proposal to django development to allow both types of apps to run 
in harmony.  Please chime in here if you would like to see this change 
added to Django itself.  I will gladly prepare the pull request.  There is 
a ticket which is waiting for feedback.  It is kind of a 'meh' change or 
feature addition, for sure, but not entirely useless.  If you think it 
could help, a little support may put it over the edge, as it is also an 
almost trivial change - the altered function is posted.
https://groups.google.com/forum/#!topic/django-developers/dk4KnILN68k

Thanks in advance for any and all feedback

Regards,

Ira

Need help with db save.

[progmgppers]

Hi, I'm trying to save a new user and their profile information in same 
form and view. It is almost working, but cant get by this error.

[image: errmsg.png]

I know I have values available because I print them just before saving from 
my views.py, which is:


def addUser(request):

template_name = 'mysite/admin_adduser.html'



# Post

if request.method == 'POST':


# Form clear was requested 

if "clearform" in request.POST: 

print("clearform request")

return redirect('addusers')

elif "cancel" in request.POST:

print("cancel request")

return redirect('adminhome') 


# Data being posted   

else:

form1 = frmAddUser(request.POST)

if form1.is_valid():

newuser = form1.save()

print(newuser.pk)  
 //*This is where I verify that I actually have 
data*//

print(form1.cleaned_data['customer']) 

newprofile = 
Profile(newuser.pk,customerid=form1.cleaned_data['customer'])

newprofile.save()

return redirect('addusers')

else:

# Form is not valid, give opportunity to fix

return render(request, template_name, {"form1":form1,})


Here is my Profile model (Its very simple for testing):


# User Profile

class Profile(models.Model):

user = models.OneToOneField(User, on_delete=models.CASCADE)

customerid = models.IntegerField(blank=True,null=True,default=0)

# customerid = models.CharField(max_length=254, blank=True)


# Create the Profile record when a new user is created by

#hooking the create_user method  

  

@receiver(post_save, sender=User)  
   //*I am curious if this 
hook is causing a problem, but what are your 
thoughts**//

def create_user_profile(sender, instance, created, **kwargs):

if created:

Profile.objects.create(user=instance)


So, I know I have data, but whaen I save the profile the dataset must have 
a null in it.

Any thoughts?


Thanks

Hi,

Profile(newuser.pk,customerid=form1.cleaned_data['customer'])

should be:
 Profile(user_id=newuser.pk,customerid=form1.cleaned_data['customer'])

user is a ForeignKey, so you assign user= after performing a 
get(), or you use the form above with your pk - i.e. 'the user record whose 
id field (primary key) is ..."

Re: How to transfer django projects from one pc to another

[Ira Abbott]

If DB is local postgres, or mysql, export data on old machine and import on 
the other after migration.  This may takes some experimentation to get keys 
importing properly.

If external and managed (say RDS), then migrations are not needed - the DB 
is already there and populated.  The above export / import applies when 
migrating that though.

How to send parameters to templates and adjust the page url by path?

Re: How to send parameters to templates and adjust the page url by path?

[Ira Abbott]

hi,

This is not much to go on:  The 'parameters' are called 'context'

You can read: 
https://docs.djangoproject.com/en/2.1/ref/templates/api/

to learn about templates and context.  

adding context in a view is done by adding context to a view as follows:

def get_context_data(self, *args, **kwargs):
data = super().get_context_data(*args, **kwargs)
data['title'] = 'New User Signup'
data['login_url'] = '/accounts/login/'
return data

'adjust the page url path' could mean one of two things:
- access the url path in the view (self.request.path) and then adjust 
context accordingly would simply the path this way and adjust 'data'
- change the url to which a page responds or assign a new url to a view - 
this is done in urls.py via a regualr expression.

Please elaborate - you have to provide information to get it.

Regards,

Ira

Re: function get_form_kwargs() not being called

[Simon A]

I double checked, this view is unique.

here's the whole process by the way.

from a detail page, there is a link that redirects to a create note page. 
also, the id of the parent object.
Create note

then on my url.py, I have two paths pointing to the same view class. one 
has no parameter, the other has a parameter which I will be using.
path('note_create/', views.NoteCreate.as_view(), name='note_create'),
path('note_create_param//', views.NoteCreate.as_view(), name=
'note_create_param'), # this is what I'm using


here's my view
class NoteCreate(CreateView):
login_url = 'login'
model = Note
form_class = NoteForm
success_url = reverse_lazy('file_status:list')

def get_initial(self):
print('at get intitial method')
return None

maybe I'll start another crud cookie cutter project to see if the get 
initial method will work on that.
