After uploading image is not displaying in production server.

[Salima Begum]

Hi all,
In my project after depl;oying into production server When i have uploaded
images it saves into media folder but not displaying image in template. As
well as when we go to the admin site and to display an image when I click
on the url of the image it is throwing an error like. url not found.

But in the media folder the image is saved and when I double click on that
image is opened. and when i upload an image from the admin site, the image
is displayed in a template.

Actually in development server uploading displaying images is working good.
After deploying into the production server I have this issue. Please help
me to solve this issue.

**settings.py**
```
# managing media
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
```

Project urls.py

```
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
```

Thanks
~Salima

Re: PayPal Integration

[Eric 247ERICPOINTCOM]

Thank you Sharif, I have integrated successfully with paypal after going
through the paypal developer docs, and tested it with sandbox.paypal and it
is working great.

However I would like your help, to now be able to submit  the form
automatically after making the payment with paypal. I have tried adding
type="submit"  to the paypal button but that doesn't work.  How can I do
that?

Glad to be of help.
It'd be easier for me to help you if I had a sneak peek at your code snippet, 
with which you are trying to do that.

Re: how to input list [] dynamic in python

[Derek]

This does look a programming exercise in a class...  if you ask these 
questions in future, be warned people here will probably ask to see your 
attempt at writing code first (otherwise you are not really learning to be 
a programmer).

But, OK, it seemed interesting to me,so here is one approach:

def elementswise_left_join(l1, l2):

"""https://www.w3resource.com/python-exercises/list/python-data-type-list-exercise-155.php""";
f_len = len(l1) - (len(l2) - 1)
for i in range(0, len(l2), 1):
if f_len - i > len(l1):
break
else:
l1[i] = l1[i] + l2[i]
return l1


def get_array(n):
if n == 1:
return [1,]
r = [x for x in range(1, n + 1)]
return r


curr = []
valid = True
while valid:
num = input("Enter number: ")
if num:
new = get_array(int(num))
if len(new) > len(curr):
curr = elementswise_left_join(new, curr)
else:
curr = elementswise_left_join(curr, new)
print(curr)
else:
valid = False

Re: Filtering fields in http response data from http request url ?

[Sam Chaffy]

Using django rest framework, create a serializer class and specify the
right field you want to display at the end.

Please check this link

Instead of telling people how many days you've spent trying to fix the
error, try spend some time on explaining what you've spent the days on
doing and what you're trying to achieve.

That will greatly improve your chances of getting help.

Re: Help with a huge database query.

['odrzen' via Django users]

If I use the values() or values_list() the request in database has a long 
waiting time and some time I also got a MemoryError (because 4GB RAM is not 
enough).
My examples:

Apple.objects.select_related('Orange').filter(state='fresh').values_list(
# Fields I don't want:
'field1',
'field2',
'field3'
# . ,
'field37'
)

( yes I want 37 different values ).

I also try with .only() with very nice response time, but in the end I will get 
all the fields. For example:
temp = Apple.objects.select_related('Orange').filter(state='fresh').only(
'field1',
'field2',
'field3' )

temp_json = serializers.serialize('json', temp)
return HttpResponse(temp_json, content_type='application/json')

it returns me all the fields! Not only the 'field2', 'field2' and 'field3'.
Could you explain me why ?

Finally, I also tried to run a query with raw() but the response time is 
disappointing.

Using jsonb_array_elements with querysets

[Jameel A.]

I’m trying to use the jsonb_array_elements Postgres function with querysets 
but I am running into issues.

I defined a custom Func as:

class JsonbArrayElements(Func):
function = 'jsonb_array_elements'

While this does seem to result in proper sql when used in an annotation, 
the issue comes when I try to filter on the new field. Postgres doesn’t 
allow you to use the new field in a where clause without using a subquery 
first.

The query that I am trying to write is equivalent to:

select *
from (
select id, jsonb_array_elements(json_data->'some_array') as elem
from foo as foo1
union
select id, jsonb_array_elements(json_data->'other_array') as elem
from foo as foo2
) as foo_w_elems
where (elem->>'subfield')::int in (
select id
from bar
where expires_at >= CURRENT_TIMESTAMP
)

Unfortunately, even with Django’s subquery support, I have been unable to 
get a query to add the where clause to the results of a subquery.

My issue seems related to https://code.djangoproject.com/ticket/24462, but 
was curious if there is a way to use and filter jsonb_array_elements 
results in Django today without using raw sql?

I’m also investigating using the low-level query API directly, but have run 
into some issues so far.

How does django-admin work?

[J Lee]

I'm new to Django, and I've just been dazzled by the magic of Django. My 
main question is how does Django add django-admin to my path automatically 
and how does django-admin startproject create my files?

It may be wy over my head, but I welcome any and all response. I would 
like to learn from this. 

Thank you.

SVG widget for the Admin

[Mike Dewhirst]

I collect the svg source for an image from a public API and store it in 
a models.TextField. I have no difficulty displaying it in a normal view 
and my own template. Nothing special, it just emerges. I don't even need 
a 'safe' filter.


However, I really want to display such images in the Admin. At this 
stage all it displays is the svg source.


What is the correct way to make the image appear in the Admin?

Do I need a special field inheriting from TextField? Do I need a special 
widget? Is there a way to mark admin field values as safe?


Thanks for any hints

Mike

Re: How does django-admin work?

[Thomas Lockhart]

Welcome to Django!

Django does not add django-admin to your path. Rather, when Django is installed 
it (sometimes) happens to be installed into a place which is already in your 
path. Otherwise, you need to add it to your path or use a packaging system such 
as anaconda which helps do that for you.

startproject simply copies a set of files to your directories, filling in a few 
details and changing the file names to match what you want to create since you 
give it the name of your new project.

Inlined hierarchy models in django admin site.

[Ayush Bisht]

class Patient(models.Model):
 patient_id = models.CharField(max_length=60)


class PatientVaccineStatus(models.Model):
  patient = models.ForeignKey(Patient, 
related_name="patient_vaccine_status")

class Vaccine(models.Model)
 vaccine = models.ForeignKey(PatientVaccineStatus, 
related_name="vaccine_status")
 
..

Is there any way to merged all the tables in a single table of patient.

I successfully merge, PatientVaccineStatus table with Patient table, but 
Vaccine's table is not merging with the Patient. 

how can this hierarchy be merged in a single table.
