You'll need to use JavaScript and XHR to send data to the server without refreshing the page. What makes you think the POST would be janky and insecure?

Hello,

I'm somewhat new to Django/front end web development so I'm wondering what the best way to accomplish this would be. I have a "Rule" model which is made up of a few other models. On the view page, I'd like to list all the Rules with their associated attributes. In each Rule, I'd like the user to be able to edit it and adjust the attributes in the model which is associated with the Rule. Once they click save, I'd like to update the relevant models in the database and reflect that on the page, but I DO NOT want the page to refresh. I know I can do this using a JS library but it seems, from my research, that'd I'd have to create a rather janky and potentially insecure POST request. I could use ModelForms, but I'm unclear how I basically keep the entire page from refreshing rather than just the individual Rule being edited. Any advice on how to accomplish this is GREATLY appreciated. Thanks!

Now, I'd like to implement some progress bars that shows the level of completion of these processes and then get the output and show it on the results page.
I search alot about how to do that and I found some blogs about using Celery with a broker like RabbitMq or Redis to perform an asynchronus task along with the django project which loads an html page showing the progress bar and I tried to use this library
https://github.com/czue/celery-progress
and I performed all the installation steps one by one however, the progress bar doesn't appear while I can't find any logs for the celery where I can figure out what is going wrong?

I'm asking about if there is an already implemented example with the same scenario which I can use or a better way explaining how to use celery and where can I find logs coming out of celery?

Django Admin is customizable to an extent, but at a certain point those customizations can cost you more time than they save, and it makes more sense to build your business logic in a standard app/view. Without digging into your code, my spidey sense tells me your app is at that point - stop trying to do it in the admin and you'll have all the control you need or want.

I wrote page one with the Django flatpages app:

But it's not real comfy in terms of editing and maintaining. So I looked on-line for solutions and of course nothing with "help" in the search terms is going anywhere fast (finds me a lot of help about Django ;-). so better keywordss needed but I have found a pile of maybe options and am suddenly bamboozled by what is vogue, current, maintained, has a lasting future etc.

https://github.com/klen/django_markdown

Untouched in 4 years with 22 open issues Hmm.

And this looks nice:

https://github.com/mjr27/django-flatpages-tinymce

but untouched in 7 years and 4 open issues.

Now untouched doesn't mean bad, could just be mature, stable and works perfectly, already fro 7 years. These are the things it's hard to gauge. But if I'm looking at TinyMCE how about:

https://github.com/aljosa/django-tinymce

on which it depends. NO bad, updated a month ago to make it work with Django 2.1 so seems alive! But my site is math heavy so I want equation ease so how about:

And this looks good:

https://www.codecogs.com/latex/integration/tinymce_v3/install.php

This looks maybe:

https://github.com/iCAPLyon1/tinymce-formula

This looks unconvincing:

https://github.com/foraker/tinymce_equation_editor

and do we want this:

https://github.com/Tivix/django-flatpages-nav

or this as well:

Or hang on why do this piecemeal why not use Wagtail from the word go:

http://docs.wagtail.io/en/v2.4/index.html

Or would wagtail introduce too much coordination trouble between its templates and my sites ... etc. etc. I'm full of questions and really just wondering, is there a canonical solution to a site documentation page hierarchy and managing it nicely?

≪ Previous: Re: Providing help on a website (basic CMS for on-site site documentation)

I'm really unsure django is the right thing for this, because it is a WEB framework. Meaning its for the construction and development of high quality web applications.

You could definitely do a speech recognition addin to django, but if you don't need the browser interface or server deployment, I'd suggest you look at writing a python command line program instead .In order to get this working with django, you would need to have a browser side interface to capture the audio and send it to django via ajax, and then have the server process the audio and return a response in which the browser renders. That requires you to use two languages at minimum, and from what it sounds like, you are not familiar with django at all. That's a substantial learning curve to tackle in a month, let aside designing, implementing and packaging a research project.

If I were you, I'd just make a command line program with python and have it execute directly on the machine being used. No need for Django or web frameworks for this, and the smaller scope means you'll probably make the deadline without a great deal of additional stress.

≪ Previous: DjangoCongress JP 2019 will be held in May. Waiting for your participation and talk!

@N Muchai,

I don't know if you've found a workaround to this, but here's mine if people are interested in the future.

I just made a custom ASGI application that adds the tenant schema name (provided your URLs are in the form *.domain.com, where * represents the schema name) and whether the project is multitenant or not. I haven't thought much about whether the boolean for multitenancy identifier helps, so feel free to remove it in your implementation. I just stacked this application in my project's `routing.py` file. Here's the code I have at the moment:

My Middleware:

class MTSchemaMiddleware:
    def __init__(self, inner):
        self.inner = inner

    def __call__(self, scope):
        if "headers" not in scope:
            raise ValueError(
                "MTSchemaMiddleware was passed a scope that did not have a headers key "
                + "(make sure it is only passed HTTP or WebSocket connections)"
            )

        for key, value in scope.get('headers', []):
            if key == b'host':
                schema_name = value.decode('ascii').split('.')[0]
                break
        else:
            raise ValueError(
                "The headers key in the scope is invalid. "
                + "(make sure it is passed valid HTTP or WebSocket connections)"
            )
        return self.inner(
            dict(scope, schema_name=schema_name, multitenant=True)
        )

My `routing.py`:

import MTSchemaMiddleware # from wherever your Middleware class resides
application = ProtocolTypeRouter({
'websocket': <your stack>(
            MTSchemaMiddleware(
URLRouter(
chat.routing.websocket_urlpatterns
)
)
            )
})

After you do this, you will be able to access the `schema_name` and `multitenant` variables inside your consumer's `scope` like this: `schema_name = scope['schema_name']` or `multitenant = scope[`multitenant`]`.

Hope this helps someone!

Best,

Ahmed

One last question, in order to "multi-tenant-ify" Channels I think the challenge will be trickle the websocket "orgin" into the consumer from Daphne somehow as it seems there is no way to know in a consumer which tenant (unique domain) the message originated from. Without the domain you can't establish the Postgres schema, without the schema you have no tenant :-)

Please confirm this would be the approach or whether I am wrong-headed here.

Thanks for the response. Seeing that I am keeping uWSGI for the non-websocket paths, any heartache with me starting daphne and the consumers using uWSGI's attach-daemon? I do this with celery and it is a convenient way to have everything for the App managed as a unit via a single /etc/init (upstart) conf file.

Your assumptions all seem correct. Also consider that the security model of WebSockets is... interesting, so securing a multi-tenant setup is going to require a bit more work than you would merely doing the same for HTTP requests.

There are other non-Channels options around if you want to look into them, but I suspect they'll all have similar architectural challenges.

Running multi-tenant site using a fork of Django tenant schemas with tens of web servers and thousands of tenants....

Piloting a project to implement Channels for real-time notifications, etc.

I want to confirm these assumptions:

1. Channels really has no support for multi-tenant, I will have to roll my own.
2. Since uWSGI is serving us well and (at this point) I wouldn't trust Daphne to serve HTTP, I've got split paths in NGinx for uWSGI and ASGI.
3. We are running RabbitMQ, so we have to cluster it and implement channels using asgi_rabbitmq (Redis would just add yet another moving part)
4. Plan on significant additional resource requirements on the web server and serious scaling challenges.

Are their any other non-Channels options, or is it the really the only game in town?

Thanks.

Django Admin is customizable to an extent, but at a certain point those customizations can cost you more time than they save, and it makes more sense to build your business logic in a standard app/view.

I agree. How do I do that?

The entire system is in the Admin except for some trivial search and non-is_staff stuff. If I was to redo it without the Admin I would have to reinvent that entire wheel.

Specifically, how do I call an external view from within the admin? I only want to call that view if the model instance attributes demand it. That means it cannot be an optional/clickable link. It must be automatic.

Currently the admin url is (e.g.) http://localhost:8000/admin/substance/substance/1450/change/ while the substance is being edited. That url doesn't change while adding an ingredient. If the ingredient hasn't been paid for by *that* user the payment screen has to pop up. Currently it does this via modelAdmin.change_view() calling billing_payment_view()

That url doesn't change until after a successful payment when billing_payment_view() calls billing_success_view() directly. At that point the url becomes http://localhost:8000/admin/substance/substance/1450/change/payment (without a trailing slash). Thereafter valid admin urls fail to show any content..

If I make settings APPEND_SLASH False, it says 404.

Do we have solutions for this?

February 25, 2019, 6:35 pm

≫ Next: test message

≪ Previous: Re: Invalid pk \"1\" - object does not exist.

Dear All,

In Django based Job Portal (Open Source Initiative), I have few questions:

We need to find out if there are packages that can help in

1) blocking domains (such as Yandex.ru) or specific IP address that spam the site

2) Any packages that will verify if PDF/Doc file is actually a resume

3) Any packages that will verify if Video pitch is in fact a video with a jobseeker pitch and not a marketing/promo spam video of some company.

**Flag something that looks suspicious as a resume, or a promo video (having music, no voice etc)

How are others in django community dealing with such issues?

No need to answer this. I'm just seeing if googlegroups sends it me.
Haven't much from the list since gmail got itself listed in SORBS the

February 25, 2019, 9:19 pm

≫ Next: [Solved] Re: How can I refresh admin_urls

≪ Previous: test message

Thank you all for your attention. Kept me going.

The fix is to initialise the self.change_form_template to None *every*
time ModelAdmin.change_form() is called. If it is None the
ModelAdmin.render_change_form() method will dynamically create the model
instance change form. Otherwise it uses the form I give it. My problem
was it remembered that instead of doing its own thing when I had
finished with it.

I reckon it was designed to swap out the default form and completely
replace it forever. Thank heavens for open source.

Here is the only change to my code ...

def change_view(self, request, object_id, form_url='',
extra_context=None): """ self = SubstanceAdmin request = wsgi request
object object_id = substance form_url = no idea! extra_context = dict of
apps, models, admin_urls and permissions """ self.change_form_template =
None ############## this works ############# ingredients =
Substance_Ingredients.objects.filter(substance_id=object_id)
subscription = None for sm2mi in ingredients: payable, fee_type =
sm2mi.fee_payable() # eg., True, PAID_DATA if payable: subscription =
billing_subscribe(sm2mi, fee_type) if subscription: # we need to collect
money for the owner self.change_form_template = 'payment.html' context =
billing_collect_context( sm2mi, subscription, ) # get everything into
the payment_view context if not extra_context: extra_context = dict()
extra_context.update(self.admin_site.each_context(request))
extra_context.update(context) self.admin_site.admin_view( # call the
Stripe mechanism billing_payment_view( request, sm2mi, subscription,
context=extra_context, ) ) # only one sm2mi at a time break return
super(SubstanceAdmin, self).change_view( request, object_id, form_url,
extra_context )

I reckon the Admin can do anything. It just takes some head scratching

The process uses ModelAdmin.change_view()[1] to call my billing_payment_view()[2] which uses PaymentForm[3] and payment.html[4] template to pass the necessary hidden vars.

When the view executes (depending on whether payment is required) it pops up a (Stripe js) credit card collection form with a [Pay] button and that submits the detail to the Stripe API which in turn generates a token if successful or an error message and re-executes the billing_payment_view with request.POST including that detail plus all the hidden fields in the form. The view goes on to process the detail, generate a receipt, send an email to the payer and launch the billing_success_view()[5] and success.html[6] template.
