Re: jquery deployment

[Mike Dewhirst]

All versions of Django from 1.11 to 2.1 are working fine with py3.6 and 
py3.7. Only 2.2 barfs.


I now suspect my Stripe integration which is somewhat behind the wave 
front at rev 2.0.3. It too uses js heavily. That is where I'm looking at 
the moment.


I still hate js and hope someone can offer advice on managing js deployment.

Thanks

Mike

I just encountered a weird UI glitch[1] in the Admin after upgrading

I checked and found the version of jquery I'm using is 1.4.1 and 
figured that has to be contributing to the problem.


The 2.1 release note says "jQuery is upgraded from version 2.2.3 to 
3.3.1." so I dug deeper in the docs to find how it is upgraded. Can't 
find anything so far. I saw that there are Django Admin javascript 
customisations. So that might complicate matters.


Is there a best practice for ensuring I keep my projects up to date?

Thanks

doesn't it?

Don't beat yourself up :)

No-one stops looking and just waits for the answer. You have to assume your 
own motivation to find it is stronger than everyone else's. It is just good 
manners to report back so others can stop looking. And it would be bad 
manners to say you fixed it without revealing the fix. 

Actually, no-one else even looks unless they are particularly interested or 
they encountered the same problem within recent memory.

Except you. You have helped me more than once in the past and I appreciate 
it. Thank you. Ten extra points!

Re: How to use permissions on a CreateView class?

[Andrew C.]

Try clearing your browser history and info. Should also test in Incognito
or Private browser so info is saved. I have a suspicion that your browser
is saving login info and you’re just not realizing this.

problem with form

[Saeed Pooladzadeh]

Hi

I'm trying to make a simple crud applicatio and learn from it. I wonder why 
my form can't save the data. Here cames my view:

from django.shortcuts import render
from saeed.forms import SmodelForm  
from saeed.models import Smodel
from django.shortcuts import render, redirect  



# Create your views here.
def emp(request):  
if request.method == "POST":  
form = SmodelForm(request.POST)  
if form.is_valid():  
try:  
form.save()  
return redirect('/show')  
except  AssertionError as error:

print(error)
pass

 



else:  
form = SmodelForm()  
return render(request,'saeed/index.html',{'form':form})  
#
def show(request):  
smodels = Smodel.objects.all()  
return render(request,'saeed/show.html',{'smodels':smodels}) 
#

smodels = Smodel.objects.get(id=id)  
return render(request,'saeed/edit.html', {'smodels':smodels})

smodels = Smodel.objects.get(id=id)  
form = SmodelForm(request.POST, instance = smodels)  
if form.is_valid():  
form.save()  
return redirect("/show")  
return render(request,'saeed/edit.html',{'smodels':smodels})

Re: reagrding "{% csrf_token %}"issue on my web site login module

[Abdul Qoyyuum]

When you run the application and test the login, what do you see in the 
devtool's Network tab? Did you see if csrf_token is null? How about 
document.cookie? Is that also null? Is the document.cookie being passed to 
csrf_token in other ways?

Lots of ways to complete this in Angular/jQuery/Ajax or otherwise is 
presented in this document: https://docs.djangoproject.com/en/2.2/ref/csrf/

Re: Create a real small business website with Django as soon as possible!!

[Abdul Qoyyuum]

Then just use a CMS like https://wagtail.io/. Wagtail is built on top of 
Django and its enough to cover all of your requirements. But its 
recommended that you go through Django tutorial in the docs first before 
trying out Wagtail though.

If I understand correctly, you do seem to be a bit confused. May I ask 
what you are trying to achieve?


Django is a web framework meaning that it's using the HTTP protocol 
which is itself an application layer protocol. SFTP is another 
application layer protocol so you cannot really implement that in Django.


There is at least one implementation of SFTP in Python though:

https://www.paramiko.org/

But of course, that has absolutely nothing to do with Django.

So again, maybe start out by telling us what you really want to achieve?

Kind regards,

Kasper Laudrup

jquery deployment

[Mike Dewhirst]

I just encountered a weird UI glitch[1] in the Admin after upgrading to 
Django 2.2.1


I checked and found the version of jquery I'm using is 1.4.1 and figured 
that has to be contributing to the problem.


The 2.1 release note says "jQuery is upgraded from version 2.2.3 to 
3.3.1." so I dug deeper in the docs to find how it is upgraded. Can't 
find anything so far. I saw that there are Django Admin javascript 
customisations. So that might complicate matters.


Is there a best practice for ensuring I keep my projects up to date?

Thanks

Mike

[1] With a m2m (self) adding another instance clicking on the {SHOW} 
link just relocates to the top of the page. Has to be a jQuery thing 
doesn't it?

Re: Accessing request from form

For the use case above, I had an epiphany did some more experimenting and
figured out how to update the audit fields without needing to mangle a
Form/ModelForm, entirely from the CBV:

 def form_valid(self, form):
form.instance.updated_by = self.request.user
return super().form_valid(form)

Fully compatible with an implicit ModelForm, and only 3 lines of code!

This is an easy drop in a view mixin, which I already have for other
overrides anyway. However, this feels really gross, and I feel like I'm
violating some prime directive by attaching data to an instance that was
not validated by the form. I think I can forgive myself since the data I'm
attaching is coming from Django and not some other source, and I have to
assume Django handles these things properly.

Of course while writing this message, I then stumbled on this exact
solution buried in the Django docs:

https://docs.djangoproject.com/en/dev/topics/class-based-views/generic-editing/#models-and-request-user

So, feel free to ignore me. I will grant myself a point for coming up with
the same solution already blessed by the Django devs. I'm also deducting a
point from myself for not RTFM properly, so I break even.

Accessing request from form

[James Schneider]

Does anyone know a philosophical reason (or I suppose a technical one,
although I don't think that's the case) why the request is not made
available by default in ModelForms when using CBV's?

Almost all of the models I use have "audit" fields (created_by, updated_by,
etc.) that reference the current logged in user. A ModelForm has no access
to the current request, and as such can't update these fields without a
User object. I have other use cases as well, but this one is probably the
most prevalent among other developers.

At any rate, I'm currently stuck having to create relatively empty
ModelForm shell classes for the simple reason of including a form mixin
that grabs the request before __init__() (because the ModelForm complains
if I don't), and overrides save() to save the fields with the user object,
in addition to specifying the form_class in the CBV along with a view mixin
for sending the request over via get_form_kwargs(). It's quite a process,
especially when dealing with multiple models. I could drop a significant
amount of code if I could flag the CBV to include the request with the form
initialization. Heck, there could even be some magic to have the form
associate the user with specific fields on save from the view as
form_kwargs.

Or am I making things hard on myself? Thanks.
