facing aws s3 image file path issue?

[prateek gupta]

Hi All,

I have created a bitbucket and some folders inside that with following 
path: my_bucket\merchant\logos\
I am trying to upload a image file inside the my_bucket\merchant\logos 
folder but it is saving inside the my-merchant folder instead of logos.
PFB my code snippet-

config.json-

{
  "AWS_STORAGE_BUCKET_NAME": "my_bucket",
  "AWS_ACCESS_KEY_ID": "MY_KEY",
  "AWS_SECRET_ACCESS_KEY": "SECRET_KEY",
  "S3DIRECT_REGION": "us-east-1",
}


settings.py-

AWS_STORAGE_BUCKET_NAME = ENV_TOKENS.get('AWS_STORAGE_BUCKET_NAME')
AWS_ACCESS_KEY_ID = ENV_TOKENS.get('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = ENV_TOKENS.get('AWS_SECRET_ACCESS_KEY')
AWS_BASE_DOMAIN = 's3.amazonaws.com'
AWS_S3_CUSTOM_DOMAIN = '%s.%s' % (AWS_STORAGE_BUCKET_NAME, AWS_BASE_DOMAIN)
STATIC_URL = '/static/'
MEDIA_FILES_LOCATION = 'merchant'
MEDIA_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, MEDIA_FILES_LOCATION)


models.py-

def logo(self):
logo_name = '{}{}'.format(self.name, '.png')
s3_key_name = os.path.join(settings.MEDIA_FILES_LOCATION, 'logos', 
logo_name)
print("s3_key_name::",s3_key_name)
# Generate file URL
bucket_name = settings.AWS_STORAGE_BUCKET_NAME
s3_endpoint = settings.AWS_BASE_DOMAIN
file_url = 'https://{}/{}/{}'.format(s3_endpoint, bucket_name, s3_key_name)
print("file_url::",file_url)

return file_url


The print values in above functions are-

s3_key_name:: merchant\logos\example.png
file_url:: https://s3.amazonaws.com/my_bucket/merchant\logos\example.png


Can anyone please help me to solve how the set the path correct and instead of 
saving image url how to save actual image?

Please correct my aws s3 path for image loading in Django 2.0.6!

[prateek gupta]

Hi Experts!

I am trying to upload an image inside the following AWS S3 path:
*pg-merchant/merchant/logos*
But the image is uploading inside the following path:*pg-merchant* instead 
of storing inside the *logos *folder; pfa screen of the same.



I am suspecting there must be a mistake in my code but I am unable to find 
it out so need your help here.
PFB my code snippet-

*config.json*-

{
  "AWS_STORAGE_BUCKET_NAME": "pg-merchant",
  "AWS_ACCESS_KEY_ID": "",
  "AWS_SECRET_ACCESS_KEY": "",
  "S3DIRECT_REGION": "us-east-1",
}




*settings.py*-

AWS_ACCESS_KEY_ID = ENV_TOKENS.get('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = ENV_TOKENS.get('AWS_SECRET_ACCESS_KEY')
AWS_BASE_DOMAIN = 's3.amazonaws.com'
AWS_S3_CUSTOM_DOMAIN = '%s.%s' % (AWS_STORAGE_BUCKET_NAME, AWS_BASE_DOMAIN)
STATIC_URL = '/static/'
MEDIA_FILES_LOCATION = 'merchant'
MEDIA_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, MEDIA_FILES_LOCATION)
DEFAULT_FILE_STORAGE = 'ps_cms.custom_storages.MediaStorage'




*models.py*-

@property
def logo(self):
logo_name = '{}{}'.format(self.name, '.png')
s3_key_name = os.path.join(settings.MEDIA_FILES_LOCATION, 'logos', 
logo_name)

# Generate file URL
bucket_name = settings.AWS_STORAGE_BUCKET_NAME
s3_endpoint = settings.AWS_BASE_DOMAIN
file_url = 'https://{}/{}/{}'.format(s3_endpoint, bucket_name, s3_key_name)

return file_url



forms.py-

def _upload_logo(self, logo, merchant_name):
ext = os.path.splitext(logo.name)[1]  # [0] returns path+filename
logo_name = '{}{}'.format(merchant_name, ext)

s3_client = self._get_s3_client()
s3_key_name = os.path.join(settings.MEDIA_FILES_LOCATION, 'logos',

Re: Please correct my aws s3 path for image loading in Django 2.0.6!

[Jason]

I think the issue is s3_key_name

S3 is *not* a file based structure, it is simply a key-value object store.  
Much like a python dictionary.  However, there are some abstractions to 
mimic folders and paths with S3, and that's indicated by using / in the key 
name.  Your key name is using slashes in the other direction, which aren't 
processed by S3 as folder names.

Can I use django-location-field module in Production?

[prateek gupta]

Hi All,

I am auto populating latitude and longitude fields once user entered the 
address in a address form.
For this task I am using https://pypi.org/project/django-location-field/

from location_field.models.plain import PlainLocationField


I need to know can I use same module in Production? Is there any license 
issue for using this in Production?
If yes, what is the alternate of this?

Using a ressource amongst several uwsgi processes

[s . baumgarten . berlin]

Hi all,

I am building a chatbot right now and am initiating the 'chatbot-agent' 
globally in the views.py, so that it wouldn't have to be loaded/initiated 
for each API request.

*#global variable in views.py:*
*agent = Agent.load('/usr/src/app/models/current/dialogue', 
interpreter='/usr/src/app/models/current/nlu')*

Unfortunately, this initiating happens once per process defined in the 
uwsgi file. Since I do want to use multiple processes for my application, 
but need only one agent-ressource amongst all these processes, my question:

How can I use one ressource amongst several uwsgi processes in my Django 
application?

Thanks a lot!

Steffen

Re: Django Channels 2.0 websocket crashing & blocking while using aiohttp

[Nathan Bluvol]

Hi Andrew,
Thank you for your quick reply. I use AsyncConsumer in the background 
worker because it seems to route properly (i.e. without error). If I create 
a new class, then I run into scope issues or simply a TypeError where the 
'backgroundConsumer object is not callable'. *The reason for all of this is 
that when I originally had my external websocket code directly inside 
consumer.py, it ended up blocking any incoming/outgoing communication 
between the AsyncWebsocketConsumer and the browser - probably because, as 
you said 'your listen() method is blocking...[because it]listens on it 
for messages forever'.* Since I am new to asyncio development, I figured 
the best way was to run the external websocket in a background worker, 
asynchronously, and then maintain my websocket consumer for dynamic browser 
updates - which "works" but apparently not for so long. Is there a better 
way to architect this that you suggest? By the way, you've done a terrific 
job with channels...

Here is my routing, so that it's clear what I am doing:

*routing.py*

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter, 
ChannelNameRouter
import dashboard.routing
from dashboard.backgroundUpdater import backgroundConsumer

application = ProtocolTypeRouter({
# (http->django views is added by default)
'websocket': AuthMiddlewareStack(
URLRouter(
dashboard.routing.websocket_urlpatterns
)
),
'channel': ChannelNameRouter({
"toggle": backgroundConsumer,
}),
})

Thanks Jason, this was the exact issue and now I am able to fix this by 
using below loc-

s3_key_name = posixpath.join(settings.MEDIA_FILES_LOCATION, 'logos', logo_name)

Re: Django Channels 2.0 websocket crashing & blocking while using aiohttp

[itsnate_b]

Further to the message above - I moved everything into the consumers.py 
file and routed to the class inside of there. Still getting this error 
AFTER I get the print statement 
print('awaiting t1')

I have confirmed that this occurs after this runs successfully: background 
worker sends a message to the group -> websocket consumer picks it up at 
the handler -> handler sends it to the browser -> browser/javascript 
recieves it and uses the data -> *error below*

awaiting t1

Re: I am trying to create polls project as mentiioned in the django website

[itsnate_b]

I'm assuming you already did this? 
django-admin startproject mysite

If so, then you should have a mysite folder, inside of another mysite 
folder. Inside of there you should have views.py, models.py. You may need 
to create the urls.py file, if it's not already there.

should look like what is shown in the tutorial...

mysite/
manage.py
mysite/
__init__.py
settings.py
urls.py
wsgi.py

Re: I am trying to create polls project as mentiioned in the django website

Hello mate,
Since you are in the beginning stages I would suggest that you start a new
project and check the urls.py again inside the project directory. If not
let us know!
Kind Regards,

Query about django

[Navjit Kaur]

Hello,

I have recently started learning about Django. Before I start making
projects using Django I just wished to read about it first. So, I visited
to the Django website.

https://www.djangoproject.com/start/overview/

At there, in the various features of Django there is one feature that is

'Fully loaded: Django includes dozens of extras you can use to handle
common Web development tasks. Django takes care of user authentication,
content administration, site maps, RSS feeds, and many more tasks — right
out of the box."

Can you please explain-"common Web development task" here.

Re: Django Channels 2.0 websocket crashing & blocking while using aiohttp

[itsnate_b]

I am unable to determine the cause of the handler issue (assuming 
something is crashing the channels websocket?). Could this be a redis queue 
issue? Where events being passed through the channel layer are filling up a 
queue and not being flushed correctly? I have no idea where to go from 
here

 3.1.3.

 Background:
 I am connecting to an external websocket, asynchronously, using aiohttp 
 within a background channels worker. Once triggered, the socket connection 
 stays alive, listening/streaming, and sends incoming messages to a 
 consumer 
 through a group_send. The consumer receives it at the appropriate handler, 
 however, after some time, it appears that the channels websocket dies and 
 the handler can no longer be found - I get 'No handler for message 
 type' even though it has been working successfully until that 
 point. Second issue is that 'await t1' seems to block in the background. I 
 route the 'toggle' to backgroundUpdater.py.

 *consumers.py*:

 from channels.generic.websocket import AsyncWebsocketConsumer
 import json


 class MyConsumer(AsyncWebsocketConsumer):

 async def connect(self):
 await self.channel_layer.group_add('myGroup', self.channel_name)

Help with context_processor

[Mikkel Kromann]

Hi.

Once again thanks for all your invaluable advice to me so far. Now, I'm 
battling context_processors.
I really struggle to find a good example that can help me understand how to 
use them.
They seem quite helpful to a lot of stuff I plan to do.

I think I got the configuration in settings.py and @register right as my tag is 
accepted as registered.
What baffles me is whether to include "request" as argument to my context 
processor GetItemDictionary() 
The error I get now (without declaring request as an argument) is 

"GetItemDictionary() takes 0 positional arguments but 1 was given"


With request as argumetn to GetItemDictionary(request) I get this error:

'GetItemDictionary' did not receive value(s) for the argument(s): 'request'


Should I pass request to my GetItemDictionary somewhere in my view, or is 
that done automagically by the template?
I realise that I've probably done something wrong elsewhere, but I'm at a 
loss to guess where ...
I suspect that the @register.simple_tag stuff I do may be the culprit as 
the tag may not be simple.


thanks, Mikkel

>From project/app/templatetags/items_extra.py
from django import template
register = template.Library() 

@register.simple_tag()
def GetItemDictionary():
# For now pass a hardcoded dictionary - replace with query later

Re: Query about django

[Andréas Kühne]

Common web application tasks :-)

Seriously though - Django makes it easy to do things that you may want to
do with a web application, for example:
* Handle forms for adding / updating items in a database
* Competent ORM.
* User authentication / authorization
* Simple admin interface
* Handle dynamic webbpages.
* Send dynamic email.
* Create just about anything you need to be able to create on a web
application.
* Also because Django is written in python you get access to all of the
Python tools and plugins.

I think the question is rather - what CAN'T you do with Django? :)

It is one of the most competent allaround frameworks I have ever seen.

Regards,

Andréas

Re: Help with context_processor

[Andréas Kühne]

First of all - that is not how a context processor works.

You are confusing template tags and context processors. A template tag is
one of the following:
https://docs.djangoproject.com/en/2.0/howto/custom-template-tags/

It must then be registered and then included in your template. So then you
should put it in the templatetags module and load it into your template. It
should NOT be added to the OPTIONS dictionary.

However, a context processor is called EVERYTIME a request is handled and
returns it's content to the template - WITHOUT the need of calling anything
OR adding it to your template. So in your case you would need to move the
context processor from the templatetags module, not load it with register,
and also load use {% include %} in your template. And finally don't call it.

What happens with the context processor is that it autmatically gets called
and the dictionary result is added to the context of the template.

So your context processor should look like this:
def GetItemDictionary(request):
# For now pass a hardcoded dictionary - replace with query later
return {
'year': {'name': 'year', 'readable': 'Year', 'urlname': 'year_list'
},
'region': {'name': 'region', 'readable': 'Region', 'urlname':
'region_list' },
'location': {'name': 'location', 'readable': 'Location', 'urlname':
'location_list' },
}

Without registering it or anything.

This way you will be able to get the information in your template like this:
{% block sidebar %}

{{year.readable}}
{{region.readable}}
{{location.readable}}

{% endblock %}

The reason for needing to add year, region and location, is because that is
the way you are creating the dictionary in your context processor.

Best regards,

Andréas

Django formset for models without foreign key

[HashRocketSyntax]

I'm trying to use formset to create connections between my Neo4j nodes. 
These models have been constructed using the django-neomodel package. They 
aren't related using foreign keys, but since this *isn't* an inline formset 
that 
shouldn't matter, right?


*models.py*

class Person(DjangoNode):
  uid = UniqueIdProperty()
  name = StringProperty(max_length=50)
  created_at = DateTimeProperty(default=datetime.now)

  friends = RelationshipTo('Friend', 'FRIENDED', model=FriendRel)

  # DjangoNode class must have a Meta class and documentation specifies 
'django_node'
  class Meta:
app_label = 'django_node'

class FriendRel(DjangoRel):
  created_at = DateTimeProperty(default=datetime.now)

  class Meta:
app_label = 'django_rel'


*forms.py*

class PersonForm(forms.ModelForm):
  class Meta:
model = Person
# don't need fields for automatically assigned keys like `uid` and 
`created_at`
fields = ['name']

class FriendRelForm(forms.ModelForm):
  class Meta: 
model = FriendRel
exclude = () #"creating ModelForm without either 'fields' || 'exclude' 
attribute is prohibited"
FriendRelFormSet = formset_factory(FriendRelForm, extra=1)


*form.html*


  {% csrf_token %}
{{ form.as_p }}


  {{ friends.management_form }}

  {% for form in friends.forms %}
{% if forloop.first %}
  

  {% for field in form.visible_fields %}
{{ field.label|capfirst }}
  {% endfor %}

  
{% endif %}

  {% for field in form.visible_fields %}

  
  {% if forloop.first %}
{% for hidden in form.hidden_fields %}
  {{ hidden }}
{% endfor %}
  {% endif %}
  {{ field.errors.as_ul }}
  {{ field }}

  {% endfor %}

  {% endfor %}


  




I'm expecting a "friend" formset to appear in the rendered form, but am not 
quite sure how to get it there. If I add the following I get an error:

  class FriendRelForm(forms.ModelForm):
class Meta: 
  model = FriendRel
  exclude = ()
  fields = ['friends']
ERROR*** django.core.exceptions.FieldError: Unknown field(s) (friends) 
specified for FriendRel*

queryset appears empty in debugger during testing, but not in console

[mccc]

Hello,

I'm testing REST APIs with rest_framework.test.APITestCase, using their 
client for making requests and model_mommy for creating objects in the 
setUp() method.
The general working is quite simple: the view is supposed to fetch a User 
and an object, and assign permissions for the former to the latter by means 
of django-guardian's assign_perm; the test creates a user and a group in 
the setUp method, then the actual test performs a POST passing their pk's 
as payload.
The issue I'm seeing, is that when the 
User.objects.filter(pk__in=people_ids) instruction is executed, the value I 
see in the debugger is that of an empty queryset, while if I type the exact 
same line in a console connected to the same session as the debugger I see 
the actual value being found.
Then the view gets to the assign_perm instruction, and it crashes with 
an IndexError: list index out of range error on the first evaluation of the 
queryset itself, which happens on the for loop at line 247 in the file 
core.py of the django-guardian library.

Is there something obvious that I should be looking at, because I really 
cannot wrap my head around this.

Thanks,
Michele

Re: Query about django

[Artur Gontijo]

It is just what it describes in the end of the sentence: "user 
authentication, content administration, site maps, RSS feeds, and many more 
tasks"

Examples for user authentication: user registration, login, logout, etc.

How to auto fill latitude and longitude fields in Django2.0.6?

[prateek gupta]

Hi All,


I have created a store address form using Django2.0.6+Mysql+Python3.6.

Currently user has to manually fill latitude and longitude for the store 
address.

I want to auto-fill both fields once user entered the address.

Below is my current code-

models.py-

class Store(models.Model):
building = models.ForeignKey(Building, related_name='building', 
on_delete=models.SET_NULL, blank=True, null=True)
name = models.CharField(max_length=100)
postal_code = models.CharField(max_length=6)
address = models.TextField()
latitude = models.FloatField(validators=[MinValueValidator(-90.0), 
MaxValueValidator(90.0)])
longitude = models.FloatField(validators=[MinValueValidator(-180.0), 
MaxValueValidator(180.0)])
class Meta:
managed = False
db_table = 'store'


admin.py-

class StoreAdmin(admin.ModelAdmin):
list_display = ('id', 'name', 'postal_code', 'address', 'latitude', 
 'longitude')


Can anyone please help me how to achieve this requirement?
