Re: Webinterface for python script

[Scot Hacker]

Make a basic Django view. Place your script in a python module that lives 
inside your app. Call that module/ function from the Django view. See 
Django docs and tutorials on how to handle uploaded files. Pass the 
uploaded file to your module, and handle the return value(s) however you 
want. Hard to get more specific than that without seeing your code, but 
this should come together pretty quickly with some experimentation.

I never know what people mean by "Django is overkill for...". Django is 
lightweight and starts up very quickly, even with large/complex projects. 
Django saves you mountains of time compared to Flask, which makes you go 
shopping for every little piece of framework you need. Every time I've 
experimented with Flask, I've come running back to Django after realizing 
my time is too valuable to waste it on creating my own framework when a 
perfectly great one already exists.

Re: TemplateDoesNotExist at /vmail/inbox/

[Alex Kimeu]

It means the template you are trying to render is either not created or not
in the location where Django expects to be. Django does not see the
template you are trying to render.

get_expiry_age does not use expire_date column.

[Shen Li]

Hi community,

I find it strange that in the DB session backend, the get_expiry_age does 
not actually use the value from expire_data column in the model.

What is the indention of this design?

Thank you!

RE: Admin form_url breakout problem

[Matthew Pava]

The flow looks fine.  And when you click refresh on your browser on step 4 does 
the page refresh properly?

Perhaps it's a caching issue.
Are you wrapping the billing_payment_view with admin_view()?
https://docs.djangoproject.com/en/2.1/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_urls
 --> scroll towards the bottom of that section

Subject: Re: Admin form_url breakout problem

Matthew

I was wrong. I'm still in trouble. I thought it might be an incomplete 
transaction so I tried making the the subscription.save() atomic but to 
no avail.

Here is what happens ...

1.  Add an ingredient which is payable

2.  Save mixture

3.  SubstanceAdmin.change_view() establishes ...

     subscription = None
     if ingredient.is_payable():
     get or create a subscription record and populate it with fee, 
gst etc.
     if the subscription.token field is blank (ie not paid):
     call billing_payment_view() which interfaces with Stripe 
via a js popup and
     a) gets a token in a hidden field
     b) calls Stripe.charge(token) and gets a json charge 
record back
                 c) populates the subscription.token field
     d) saves the subscription record
     e) creates a receipt record
     f) sends an email receipt
     g) puts thank you text and mixture url into context dict
     h) calls billing_success_view(request, context) to 
display success
    message including link back to mixture
     return super(SubstanceAdmin, self).change_view()

4.  On clicking the back-to-the-mixture link in success.html, the Admin 
brings
     up the Change Substance page without error but which is blank below the
     "Change Substance" heading. At that time the displayed URL in the 
address
     bar is exactly correct.

5.  If the dev server reloads the page will paint properly if refreshed.

Theory:

The subscription record has been saved but not in a way which is visible 
yet thereby confusing change_view() into thinking the token field is blank.

In other words the transaction needs to be committed 
pre-billing_success_view()

In testing this it sadly this makes no difference.

 Hi Mike,
 When Stripe processes the payment, you need to preventDefault on 
 the form submit, then add the token from Stripe to a hidden input 
 in your form without affecting any other data in the form.  Then 
 you can do form.submit() and let the admin handle it from there.  
 Check out the Stripe documentation for some good examples.  I've 
 used it myself.

Re: Django timezone problem

[Mikko Meronen]

Hi,

Thank you for your answer. I tried timezone.now without parentheses, but it
gave me server error. I have also tried datetime, but I face the same issue.

The issue I have:
I want people to see what happened today in the past. So I created a
database where is a story or stories what happened in the history on this
day(date). My view should be able to pick a right story from the database
based on the users timezone. If Australian visits my webpage at this
moment, he should be able to see what happened on February 5 in the past
(it's already February 5 there). However he sees what happened on February
4, because it is February 4 here (in Finland or England, not sure what
timezone I'm using). So I want to make my view to understand the end user's
local time, so it can pick the right story from the database for the
webpage visitor.

Re: Passing pk arguments from a URL into another view

[Gavin Boyle]

Hi Pooya,

Once I’ve done the include, how can I then pass that PK into the view of
the included urls?

Thanks

This for loop has variable named conferenc but in the urtl tag the name
conference is used. The same name needs to be used in both places. (If you
change to conference note the use of conferenc to show the title will also
need to change.

(Thanks for all the detail in the question!)

django kwargs are not passed with the view to html template

[Mohammed Modhaffer]

I searched for hours but I could not find a solution. I am trying to filter 
conferences by country. Conference detail url works fine when I click on it 
from the main conference list. When I filter by country, the list of 
conferences in a given country are shown. However, when I click on a 
conference, it breaks and shows `Reverse for 'conference-detail' with 
keyword arguments '{'pk': '', 'slug': ''}' not found. 1 pattern(s) tried: 
['conferences\\/details\\/(?P[0-9]+)\\/(?P[-a-zA-Z0-9_]+)\\/$']`. 
I cannot figure out the problem in my code. 

Model:
  
from cities_light.models import Country, City
class Conference(models.Model):
title = models.CharField(max_length=512, default='')
slug = models.SlugField(max_length=512)
country = models.ForeignKey(Country, on_delete=models.CASCADE)
city = models.ForeignKey(City, on_delete=models.CASCADE)

def __str__(self):
return self.title

def save(self, *args, **kwargs):
self.slug = slugify(self.title)
super(Conference, self).save(*args, **kwargs)

def get_absolute_url(self):
return reverse('conferences:conference-detail', kwargs={'pk': 
self.pk, 'slug': self.slug})

urls.py:

 

path('', views.ConferenceListView.as_view(), name='conference-list'),
path('details///', 
views.ConferenceDetailView.as_view(), name='conference-detail'),
path('country-list', views.ConferenceCountryListView.as_view(),
 
name='conference-country-list'),
path('country///', 
views.ConferenceByCountryView.as_view(),
 
name='conferences-in-single-country'),

Views:

class ConferenceByCountryView(generic.ListView):
template_name = 'conferences/conferences_in_country_list.html'
context_object_name = 'conferences'

def get_queryset(self, *args, **kwargs):
country = Country.objects.get(pk=self.kwargs.get('pk', None))
return Conference.objects.filter(country=country)

def get_context_data(self, **kwargs):
context = super(ConferenceByCountryView, 
self).get_context_data(**kwargs)
country = Country.objects.get(pk=self.kwargs.get('pk', None))
context['country'] = country
context['title'] = 'Conferences in ' + ' country'
return context


class ConferenceDetailView(generic.DeleteView):
model = Conference
template_name = 'conferences/conference_detail.html'

def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['title'] = self.object.title
context['pk'] = self.object.pk
context['slug'] = self.object.slug
return context

In the conference list html, this is the code snippent: `{{ conference.title }}`. It redirects to the conference 
detail page without any problem. In the conference by country html, I have 
the following code: 


{% for conferenc in conferences %}
 {{ conferenc.title }}  {%comment%} Here is 
the problem. {% endcomment %}
{% endfor %} 
 

When I click on the url, it raises the following error: 

Reverse for 'conference-detail' with keyword arguments '{'pk': '', 
'slug': ''}' not found. 1 pattern(s) tried: 
['conferences\\/details\\/(?P[0-9]+)\\/(?P[-a-zA-Z0-9_]+)\\/$']

Your kind help is highly appreciated.

Re: Django timezone problem

['Amitesh Sahay' via Django users]

Hello Mikko,
There are basically two ways which I know . One is the timezone module that you 
are using another is datetime module. I believe that timezone module is more 
effective one.But instead of calling timezone.now() , call timezone.now.
Or what is the exact issue are you facing?

I have read django documentation and tried to google solutions, but I get quite 
confused. Below you will find my code. In short the code should show a story on 
my webpage what happened in the past on the current day. However it doesn't 
take into account the endusers local time, and thus doesn't work properly.

Views.pyfrom django.utils import timezone

t = timezone.now()     [This should somehow react to endusers local time]dm =

home.html[in html I have just the basic things to show the content]
                            {% for x

x.content }}      {% endfor %}

You can check my webpage (http://www.topithenewsdoggy.com/) to get better
