Re: User filling form in login session if user logout and login again data of form not to lose.

[boyuanl...@gmail.com]

 You can do that by calling an endpoint in JavaScript. So when the field's been 
changed, automatically called the endpoint in Django and store it into the 
database. When a user's logged back in, just render the existing data if 
there's any.

Testing Django User Login Form

[lone...@gmail.com]

Hello all,

I am not sure what I am doing incorrectly with the below test case 
information.  I am simply trying to test the default authentication form of 
django 3.1.  This test should be a good/True login test.

Here is the Test case:-
class TestForms(TestCase):
def test_invalid_username(self):
# The user submits an invalid username.
data = {
'username': 'abc',
'password': 'password',
}
form = AuthenticationForm(None, data)
self.assertTrue(form.is_valid())


Here is what I am getting for output:

FAIL: test_invalid_username (rucklogs.tests.TestForms)
--
Traceback (most recent call last):
  File "/home/lonesoac0/django/rucker2021/rucklogs/tests.py", line 39, in 
test_invalid_username
self.assertTrue(form.is_valid())
AssertionError: False is not true
---

As you can see in the attached screenshot, the user abc is a good user.

Thank you.

This looks pretty straightforward:

https://devcenter.heroku.com/articles/django-assets

If you've followed that without success, you should try to explain a bit
more in detail where you are having issues, not just "can't able to done
this".

And of course, if you want someone to do it for you, you should explain
more in detail how much you're willing to pay etc.

Kind regards,

Kasper Laudrup

Actually, looking again at the source, it might be generally belter to use
self.base_fields. (Yes, my previous answer is not an exact copy of my code,
so I got it wrong).

The "how" is easy. Here is a fragment from my code where the problem is
that every instance of FilesForm has content dependent on external factors
(the "..." below):

  class FilesForm(forms.Form):
  def __init__(self, *args, **kwargs):
   self.declared_fields = OrderedDict()
   for name, field in items():
   self.declared_fields[name] = field
   super().__init__(*args, **kwargs)

The "why" is a deeper question, but in short, that's what the source code
says the DeclarativeFieldsMetaClass for forms uses. Technically, I believe
the code is a little ick because self.declared_fileds is a class member,
not an instance member and so needs the funny-looking assignment so the
instance has a value it can hack. You may need to copy the original dict as
in "self.declared_fields = OrderedDict(self.declared_fields)" depending on
your use case.

(Generally, the Django docs are amazing, but this is one area where I
needed the source.)

You most likely don't have a problem with your nginx server. Your nginx
server has a problem reading a response from your Django application
which is the reason it times out.

It can be a bit tricky to figure out the cause of the heavy load, but I
would start by looking in your Django server logs and see if there might
be something obvious there.

If you have a chance to get a look at your server while it's under heavy
load and starts giving timeouts, something like htop and similar tools
might be able to give you a hint at the bottleneck. If you're database
server is maxing out all your CPU cores, then that could give a good
hint on where to look.

Hope that helps a bit.

Kind regards,

Kasper Laudrup

NGINX AND DJANGO DEPLOYMENT ISSUE

[Sunday Iyanu Ajayi]

Hi Team

Please I am having serious issue with my nginx server.

At midnight when the traffic on the server is at it peak, my server spikes
and I get 502 error and from the nginx error log, I get :

upstream prematurely closed connection while reading response header from
upstream

upstream timed out (110: Connection timed out) while reading response
header from upstream

My server resources is about 8 core , 16GB RAM

This is seriously giving me nightmares . I need help

Mixin add field to fields in forms

[sebasti...@gmail.com]

Hello,


*forms.py:*

class Newsletterform(StandardMixin):
class Meta:
model = Newsletter
fields = ['newslettername', 'from_link', 'to_list', 
'email_subject', 'text_message', 'html_message' ]

*Mixins.py:*
class StandardMixin(forms.ModelForm):
class Meta:
abstract = True

def __init__(self, *args, **kwargs):

self.Meta.fields.append('owner')
super(StandardMixin, self).__init__(*args, **kwargs)


*i would append in Meta.Fields owner and after this super. But in Template 
this field are not shown. *

*Why?*
