how to initialize input form fields using URL parameters

[Andrew Brown]

I am trying to pass initial values to my form set via URL Query
ex) Localhost:8000?/First_name_id_0=Samuel
[image: forms.py.png]

I was told to use the initial parameter and not the instance in my view 
first

"An inline formset is related to one instance of the parent model. You 
identify *which* instance the formset is related to by the “instance” 
parameter. The “initial” parameter has a different usage, which is defined 
in the docs."

But I can't seem to find an examples in the docs
[image: Views.py.png]

How do I change my view so that that it initialize my form set with URL 
Query?

Almost a question for the PostgreSQL users list - assuming that is your 
DBMS. It will depend on so many aspects of what is actually happening 
during/after upload.


In theory, if you upload data in a single transaction - or even many 
transactions - there will be no impact on users until the moment of 
committing.


In practice, theory might be inadequate.



Thanks in advance,

John

Signed email is an absolute defence against phishing. This email has

automatically decrypt my signature and be sure it came from me. Just
ask and I'll send it to you. Your email software can handle signing.

BUG USING modelformset_factory MODULE

[Michael Maina]

Hello,

 

I have a challenge using the modelformset_factory module (
https://docs.djangoproject.com/en/3.2/topics/forms/modelforms/) and invite 
your advice. 

 

I can automatically generate a pre-populated webpage with a select dataset 
from the database, but the generated template creates two sets of fields on 
my form. One entry has the pre-populated dataset, while the second set is 
blank.
 The challenge is any attempt to update the retrieved dataset, leads to the 
creation of a new (*unnecessary*) entry in my database. Any assistance on 
how to resolve this is most welcome. Details of my setup are highlighted 
below:

Uptime all the time

[j harvey]

I am looking for ideas on how to keep my app running all the time, even 
when uploading data that will replace the current data. Some of these 
tables will have a million rows or more. Ideas?

Thanks in advance,

John
