Actually - it does.

Any time you specify a template to render, you can also specify a *list* of
templates. So, you can do something like this:

def my_view(request):
…
return render(request, [
‘path/to/template/%s/template.html’ % user_theme,
‘path/to/template/default/template.html’,
], {…context…})

That will pick the user’s theme by default; if the user’s theme doesn’t
specify a given template, or the user doesn’t have a theme (or the user’s
theme is set to default), it will use the default theme directory.

Hope that helps!

Re: add a secretballot middleware to MIDDLEWARE_CLASSES

[Fabio C. Barrionuevo da Luz]

Hello Shahab.

Perhaps the real problem is that you apparently have not completed a good
tutorial to learn how django works and how to use it.

I would recommend these two tutorials: https://tutorial.djangogirls.org/
and http://www.marinamele.com/taskbuster-django-tutorial

said that, this is the relevant documentation about django Middleware:
https://docs.djangoproject.com/en/1.11/topics/http/middleware/

Note: The django Middleware configuration on settings.py was renamed in
Django 1.10, from MIDDLEWARE_CLASSES to MIDDLEWARE .

Learn more about why this change in:
https://github.com/django/deps/blob/master/final/0005-improved-middleware.rst

About django-secretballot specifically, the available

https://github.com/jamesturk/django-secretballot/blob/master/secretballot/middleware.py#L13-L18


MIDDLEWARE = [
# other previous middleware configurations

# Add the below line, on final of MIDDLEWARE variable in your
settings.py
'secretballot.middleware.SecretBallotIpUseragentMiddleware',
]


I hope this has helped. Good studies :-)

Re: How to structure this django application

Do take the time to peruse the book. It would be time well spent. Also, do
keep in mind that the recommendations therein do not apply to a Django
blog or CRM sustem etc, per se. They would apply just as well if you were

Sithembewena,

  I recognized this the first time I considered using django.


The problem you describe of managing users etc is just a requirements
specification. The advice in the book is general enough across
implementations of solutions in broad problem domains. It's not a recipe
book, but more a collection of chefs' knives.


  My original question was not about structuring django code but the logical
design of the project itself. I believe that question was answered by a
message on another thread: there is at least one plug-in package that allows
individual users to work in their own database area and keeps users from
areas assigned to others. This is independent of the django project/app code
arrangement.

Thanks again,

Re: Just learning about auth in django and getting error NoReverseMatch ; Exception Value: Reverse for 'password_reset_done' with arguments

It's hard to tell what is wrong without the full traceback or thecode

I would suggest to replace reverse("password_reset_done") with
reverse("myapp:password_reset_done").
Might be as simple as that.

Re: Theming

[Clinton Blackburn]

Russ,

How would this work for base/nested templates? Say my view is rendering the 
potential templates ['my-theme/page.html', 'page.html'], and the templates 
inherits base.html. Do I have to override base.html for every theme if I 
want base.html (or any other child/parent template) to be theme-able? Is 
there a version of {%include%} that takes an array, or will I need to write 
my own tag?

I would like to avoid duplicating templates unnecessarily (e.g. every theme 
*has* to have all of the templates, even if there is no override) if 
possible. So far I see my options as either duplicating templates or 
writing a custom {% include %} tag that is theme-aware.

Thanks,
Clinton

Extending a image and adding text on the extended area using python pil

[Aamu Padi]

I am creating QRcode for each ticket. The QRcode is in image format.

​I want to extend this image vertically on both the sides (i.e. Top and
Bottom). And in the extended area I want to add some additional data like
this:

Theater Name
_
||
||
|   QR CODE  |
||
||
||
||
||
||
Seat id: 24 C
Movie: The baby boss
Showtime: 2:30 pm
Date: 09/04/17



Now I am doing this way to add image:

image = Image.open('qrcode.jpg')
width, height = image.size
draw = ImageDraw.Draw(image)
text_cinema = "RPG Cinema"
text_seat = "Seat: 15C Balcony"
text_movie = "The baby boss"
text_showtime = "02:30 pm"
text_date = "09/04/17"
font = ImageFont.truetype('font.ttf', 24)
draw.text((40, 5), text_cinema, font=font)
draw.text((40,height - 40), text_seat, font=font)
draw.text((40,height + 40), text_movie, font=font)
draw.text((40,height + 40), text_showtime, font=font)
image.save(str(time()).replace('.', '_') + '.jpg')


And the image turns out to be in this way:


​

As you can see, the text are added into the image and not extending the
image itself. Also, other data like text_movie, text_showtime and text_date are
not being inserted as the text does not extend the image.

How can I extend the image and insert texts into the extended image area?

Re: Extending a image and adding text on the extended area using python pil

[ludovic coues]

Look like a question for the pil mailing list.

Anyway, stackoverflow suggest that you create a new image then paste the
old image onto the new one.
Here is the code from stackoverflow

newImage = Image.new(mode, (newWidth,newHeight))
newImage.paste(srcImage, (x1,y1, x1+oldWidth,y1+oldHeight))

I fear there is no way to make the image fit your content, you'll have to
create an image big enough. I hope that won't be an issue for you

Well, as you quoted, the instruction goes on to say "see middleware section

The template loading list (i.e., [‘my-theme/page.html’,
‘page.html’]) indicates which template will be rendered. Each of those
template can, themselves, include or extend any other template they want.
So, ‘my-theme/page.html’ could extend ‘page.html’, which could, in turn,
extend ‘base.html’ - or both templates could directly extend ‘base.html’.

The argument that is passed to {% extends %} is also something that can be
paramterized - so, for example, you can pass in a variable as template
context that contains the “parent” template - so you could do something
like having “page.html” that starts “{% extends theme %}”, and then pass in
{“theme”: “path/to/theme.html”} as context.

The same applies to {% include %} - anywhere that you pass in a string in a
template could, potentially, be a variable.

The approach that will work best depends on exactly what “theming” means in
your context.

Is it the same basic structure that just has a different style sheet? Then
having a template with {% include theme %} will probably be best.

Or is it a base structure where key bits of content are different? In that
case, having a my-theme/page.html that extends page.html, and using the
template loader trick will probably be best.

Or are the same *pieces* on each page, but laid out differently for each
user?  In that case, you probably want a page.html that starts with {%
extends theme %}, so that the theme establishes basic page structure, and
the page defines the blocks that are placed into that structure.

Yours,
Russ Magee %-)

the documentation says..

Add ``audiotracks`` to your app
~~~

Edit ``settings.py`` and add ``audiotracks`` to your list of
``INSTALLED_APPS``. Then synchronize your database with::

$ python manage.py syncdb

Edit your ROOT_URLCONF_ and add a piece of code similar to::

urlpatterns += patterns('',
# Here we mount the app under /music. Feel free to use something 
else
url("^music", include("audiotracks.urls")),
# Some URLs require a Django username
url("^(?P[\w\._-]+)/music", include("audiotracks.urls")),
)

Visit the URL ``/music/upload`` to upload your first track.


but i get an error everytime i try

Re: ORM for structured Logs

For general purposes, I agree with this. Logging is a python standard, logs 
can be verbose, logrolling solutions are well established (and built in), 
etc. However, there are certain situations or activities where database 
logging makes sense, most likely *in addition to* standard logging rather 
than instead of. In one of my projects, half a dozen non-technical managers 
need the ability to track certain types of actions (related to account 
activations at a school). For this, I developed a simple ORM logging 
solution that lets those managers search and filter these special logs in 
the Django admin. 

It's not something that really deserves to be its own project, IMO - just a 
typical thing a dev might do in Django to satisfy an institutional need. 
But I've put my solution in this gist, in case its helpful:

Re: Filter list dict in JsonField Postgres

[Camilo Torres]

Hi.
I have been thinking more about this.
I think you cannot filter the list in the query with the JSONField from 
django. At most, you can get the object and filter the field in the 
resulting list.

Example with this simple model:
from django.db import models
from django.contrib.postgres.fields import JSONField
class DataModel(models.Model):
data_field = JSONField(default=dict)

You can do:
DataModel.objects.create(data_field=[{'number': '1160188479', 'id': 0, 
'content': 'hello', 'processed': True}, {'number': '1160188479', 'id': 1, 
'content': 'hello', 'processed': False}, {'number': '1160188479', 'id': 2 
,'content': 'hello', 'processed': False}, {'number': '1162341721', 'id': 3, 
'content': 'hello', 'processed': False}, {'number': '1162341721', 'id': 4, 
'content': 'hello', 'processed':False}, {'number': '1162341721', 'id': 5, 
'con tent': 'hello', 'processed': False}])
Then you can query the database to get that record:
o = DataModel.objects.get()
processed = [x for x in o.data_field if x['processed']]
Variable 'processed' will have the processed data.


If you want to query your models by having the 'processed' field to true, I 
found you can do it if you change the way you save your data, one option 
may be:
DataModel.objects.create(data_field={'*processed*': [{'number': 
'1160188479', 'id': 0, 'content': 'hello', 'processed': True}], '
*not_processed'*: [{'number': '1160188479', 'id': 1, 'content': 'hello', 
'processed': False}, {'number': '1160188479', 'id': 2 ,'content': 'hello', 
'processed': False}, {'number': '1162341721', 'id': 3, 'content': 'hello', 
'processed': False}, {'number': '1162341721', 'id': 4, 'content': 'hello', 
'processed':False}, {'number': '1162341721', 'id': 5, 'con tent': 'hello', 
'processed': False}]})
Notice I saved the data separeting the processed and the not_processed. The 
you can query objects with any of these keys:
queryset = DataModel.objects.filter(data_field__has_key='processed')
Then you can iterate over the queryset and the the data from every dict.

Anyway, to do advanced queries over that data you may be forced to save it 
in a different way. You can even save the "processed" and "not processed" 
data in different list in different JSONFields on the same model, and query 
like this:
queryset = DataModel.objects.filter(processed__isnull=False)

Binding data to one o many forms from one view - BadHeaderError at - Header values can't contain newlines ()

[Bernardo Garcia]

I have the following forms to each user profile

class UserUpdateForm(forms.ModelForm):
class Meta:
widgets = {'gender':forms.RadioSelect,}
fields = ("username", "email", "is_student",   
"is_professor", "is_executive",)
model = get_user_model() #My model User

class StudentProfileForm(forms.ModelForm):
class Meta:
model = StudentProfile
fields = ('origin_education_school',current_education_school',
'extra_occupation')

class ProfessorProfileForm(forms.ModelForm):
class Meta:
model = ProfessorProfile
fields = ('occupation',)

class ExecutiveProfileForm(forms.ModelForm):
class Meta:
model = ExecutiveProfile
fields = ('occupation', 'enterprise_name', 
'culturals_arthistic','ecological')

I have an URL which call to my AccountProfilesView class based view which 
create an instance of the previous forms according to the user profile:

url(r"^profile/(?P[\w\-]+)/$",
views.AccountProfilesView.as_view(),
name='profile'
),


My AccountProfilesView  is this:

I this moment, from the AccountProfilesView class based view I am create 
the different instances of each one of these forms, according to the 
user profile, then, if an user have the is_student profile their related 
form will be generated, and so, of this way to is_professor  and 
is_executive profiles

If an user have the three profiles (is_student, is_professor,is_executive ) 
in one single form will be created or rendered the fields of the three 
forms associated to each user profile related.

class AccountProfilesView(LoginRequiredMixin, UpdateView):
# All users can access this view
model = get_user_model()
#success_url = reverse_lazy('dashboard')
template_name = 'accounts/profile_form.html'
fields = '__all__'

def get_context_data(self, **kwargs):
context = super(AccountProfilesView, 
self).get_context_data(**kwargs)
user = self.request.user

if not self.request.POST:
if user.is_student:
profile = user.get_student_profile()
context['userprofile'] = profile
context['form_student'] = forms.StudentProfileForm()
if user.is_professor:
profile = user.get_professor_profile()
context['userprofile'] = profile
context['form_professor'] = forms.ProfessorProfileForm()
print ("profesor form is", context['form_professor'])
if user.is_executive:
profile = user.get_executive_profile()
context['userprofile'] = profile
context['form_executive'] = forms.ExecutiveProfileForm()
return context

def post(self, request, *args, **kwargs):
self.object = self.get_object()
context = super(AccountProfilesView, self).post(request, *args, 
**kwargs)
user = self.request.user
# if self.request.method == 'POST':
if user.is_student:
context['form_student'] = forms.StudentProfileForm(
self.request.POST)
elif user.is_professor:
context['form_professor'] = forms.ProfessorProfileForm(
self.request.POST)
elif user.is_executive:
context['form_executive'] = forms.ExecutiveProfileForm(
self.request.POST)
return context

def form_valid(self, form):
context = self.get_context_data(form=form)
user = self.request.user
user = form.save()
if user.is_student:
student = context['form_student'].save(commit=False)
student.user = user
student.save()
if user.is_professor:
professor = context['form_professor'].save(commit=False)
professor.user = user
professor.save()
if user.is_executive:
executive = context['form_executive'].save(commit=False)
executive.user = user
executive.save()
return super(AccountProfilesView, self).form_valid(form)

def get_success_url(self):
return reverse('dashboard')

 And in my template, I have the following small logic:


{% csrf_token %}
{% if userprofile.user.is_student %}

My Student Profile data
{% bootstrap_form form_student %}
{% endif %}
 

{% if userprofile.user.is_professor %}
My Professor Profile data
{% bootstrap_form form_professor %}
{% endif %}

Re: Binding data to one o many forms from one view - BadHeaderError at - Header values can't contain newlines ()

[Camilo Torres]

Hi,

Inside your "post" method, you have this line:
context = super(AccountProfilesView, self).post(request, *args, **kwargs)
in that case "context" is a HttpResponse object[0]. May be, from the name 
you use for the variable, you think this is a simple dict as those used to 
pass context to render functions; it is not.
You can use HttpResponse as a dictionary to put HTTP headers in the 
response [1], so line 184 is setting an HTTP header with a value of the 
HTML to render the form; that is not what you want.
You have to remove that line and create your context with something like:
context = {}
And you have to return an HttpResponse object, probably by calling one of 
the render functions [2].

Re: Annotated queryset + Prefetch object

[Simon Charette]

Hello Jose,

I wouldn't be surprised if this was caused by a Django bug with prefetches 
doing
weird things when the same model is referenced through different 
relations[0].
