Re: Django 2.1.4: Permissions are not updated after migrations

[Simon Charette]

Hello Yevgeny,

I'd start by deleting your stale content types[0] which your permissions 
are attached
to. That should deal with deleted model case.

For the renames I suggest you drop into a shell and manually edit the 
Permission.name
of the misnamed instances.

Best,
Simon

ANN: django-yamlconf 1.1.0

[Michael Rohan]

Hi Folks,

Have release v1.1.0 for django-yamlconf, a module supporting Django
settings via YAML files (searching up the directory hierarchy, e.g., in a
K8s environment, adding a "final" set of settings via "/APPLICATION.yaml",
see the documentation a https://django-yamlconf.readthedocs.io/en/latest/
for more detailed info.  The primary driver was the update to PyYAML load
function to require a Loader kwarg.

Take care,
Michael.

Re: Django's best way to upload data into a postgresql database

[Ryan Nowakowski]

Send like a pretty standard optimization scenario. I'd recommend:

1. Find the bottleneck. Here if your suspect it's pandas dataframe vs lists, 
run a timing analysis using each.
2. Remove the bottleneck

Django's best way to upload data into a postgresql database

[Guillermo Yáñez Feliú]

 

Hello,


I’m working in a project that consists in converting a local postgresql 
database (that uses sqlalchemy as the ORM) into a web application, in which 
I upload excel sheets, read them, do some small cleaning and then upload 
selected data into a postgresql database using Django’s ORM. The idea is to 
have the data in a server instead of in every user’s machine. 

Everything is ok but data loading is taking too long since, I think, I am 
using panda’s dataframes to easily structure, read and save the data. In 
the local version of the library, I used lists and was way faster.


I don’t if it’s related to Sqlalchemy, Django, lists or dataframes. Any 
suggestions on how to read spreadsheets data and upload it into a 
postgresql database using Django?


Thanks a lot.

Is MongoAtlas supported with django?

[Periklis Gkolias]

Hi,

I am trying to connect my Django app to MongoDB atlas, using djongo
. Here is my status:

I have set up a cluster successfully in Atlas. I am then getting the
connection string details from the relevant console. With that knowledge, I
am amending my DATABASES dict in settings.py

Here is the connection string:

*mongodb+srv://:@-/test?retryWrites=true*

Here is my dict.

DATABASES = {
'default': {
'ENGINE': 'djongo',
'USER': 'my_username',
'PASSWORD': 'password',
'NAME': 'test',
'HOST': '-',
'PORT': 27017

}
}


Do you find anything smelly? Has anyone done a similar setup? I would
appreciate any documentation or hints on that matter

Thanks,
Periklis

I don't have magic solution to suggest to you given the current state of

Django 2.1.4: Permissions are not updated after migrations

[Yevgeny Bar Lev]

Hello,
I have noticed that the available permissions list, which can be set to 
users/groups in the admin doesn't match my models. This happened after a 
few standard migrations, where some models were renamed, some deleted, and 
new models were added. The list is basically not updated, and represents a 
mixed state of the db, before and after the above migrations.

manage.py inspectdb show the CORRECT state of the database. 

I have tried to follow the following solution, which basically didn't do 
much.

from django.contrib.auth.management import create_permissionsfrom django.apps 
import apps

create_permissions(apps.get_app_config('my_app_name'))

I will appreciate your help.
Best,
Yevgeny.

Re: get_absolute_url in djano 2.1.7

[Ankit Anurag]

The one major use is that this function helps you avoid situations where 
you have to hardcode a URL in your templates. Instead, you use something 
like {{.get_absolute_url}} and even if you change the path in 
some way at some later point of time, it won't matter. It's basically a 
really good practice to use this function to define your URL.
Check out this link from Stack :

Execute view logic without page change | Add item to list

[Aris Almpanis]

Hello all,

Django newbie here so sorry for any mistargeted questions!

I am building an app for handling user orders and I would like to track
each user's add item request, pretty much like an 'add product to cart'
functionality.

At the moment I have a detail view where there is the option of adding the
item to the order via a button. Initially I tried connecting the button to
an AJAX get request to some url (like items/whatever/add) with the hope to
execute a view that stores the user's choice in the session data. However,
my main problem is that django responds to this request with a response
"forcing" the browser to open up a new tab and display the response - I do
not wish any change in the current page the user is wathcing.

In more general terms is there a way to call remote api in order to do
something without changing browsers current display?

Thank you in advance!

So we can use template tags related to internationalization,  such as
'trans' and 'get_current_language'
