Re: Django field model for HTML parser?

Hi fellow Djangoistas:

I'm back.

Thank you Atonis for your help.  I suppose I can leave the WYSIWYG 
editor static files for later when I have alittle more experience.  
For now though: how can I enable HTML markup to parse like it should?  
The box where users on my Django website make a blog post, they can 
attach images, apply a timestamp but the content is just plain text.  
How do I make it so that when I user for example enters this:


|
Lorem Ipsum
Hello and welcome to my first blog post
|

...that it posts and parses not as plain text but with the heading 
showing with a slightly larger font size than the rest and the first 
sentence is bolded?


That is easy but dangerous. You need to permit only a subset of markup. 
In your views you need to bleach [1] the user entered data then 
mark_safe() it. Bleach has a default set of html tags probably including 
 and  but you can add others. For all other tags it will 
convert angle brackets into > and < thus disabling them. Django's 
mark_safe will deliver any real tags to the browser.

Thanks again.

Hello,

First of all: If you are just starting to learn, and because the
amount you have to learn can be overwhelming, I'd suggest to not
care about the wysiwyg editor at this stage. Pretend that your

get some understanding of static files, only then come back to
this issue.

But to (prematurely) answer your question, if you have DEBUG=True
and running django with manage.py runserver, you shouldn't need to
care about STATIC_ROOT and STATIC_URL and collectstatic. Just
forget about them. When the time comes to deploy your application
and turn DEBUG off, then you will need to understand how static
files work in production

I’m not running Apache. My Django serving is running locally. The
absolute path in my file tree to my Django root directory is:


/home/gnull/Dropbox/TECH/python/2017/django-experiment-with-nick/dobbs_portal_blog/

Inside dobbs_portal_blog is where I placed the static folder.
Therefore, the line in my settings.py where I declare the
variable, I changed from the default:

|
*STATIC_URL ='/static/'*

to:

*|
STATIC_URL

='/home/gnull/Dropbox/TECH/python/2017/django-experiment-with-nick/dobbs_portal_blog/static/'

That is my best guess at attempting resolve the “pretty obvious”
error message:

You're using the staticfiles app without having set the
STATIC_ROOT setting to a filesystem path.


Yet I am still doing something wrong because invoking python3
dobbs_portal_blog/manage.py collectstatic, I still get the same
message:


$ python3 dobbs_portal_blog/manage.py collectstatic

Re: Django Channels Model Binding not sending messages

[Zac Kwan]

I have a console.log in my javascript that verified is the newly created 
Feed that got sent. This is my binding, consumers and routing class:

#bindings.py
class FeedBinding(WebsocketBinding):

model = Feed
stream = "feed"
fields = ["__all__"]

@classmethod
def group_names(cls, instance):
return ["feed-grp", ]

def has_permission(self, user, action, pk):
return True

# consumers.py
class Demultiplexer(WebsocketDemultiplexer):

print("consumers.py is run")
consumers = {
"feed": FeedBinding.consumer,
}

def connection_groups(self):
return ["feed-grp", ]

# routing.py
channel_routing = [
route_class(Demultiplexer, path="^/binding/"),
]


I still couldn't get the sending to work via admin or DRF API call when 
creating a `Feed` object. This somehow only happens in the production 
setup, runserver works fine.

Really appreciate your help, thanks for the great library!

Cheers
Zac

Look at models.ForeignKey ...

https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey

When you add a foreign key field to a table, the Django Admin form 
offers a choice of all the values from the table you specify.


If you are writing your own forms this might help ...

https://stackoverflow.com/questions/5104277/field-choices-as-queryset

A custom command just needs to follow a specific pattern and contain 
functions with specific names so the command can be executed like python 
manage.py fetch_web_values

I suggest you import the csv data into a table using a manage.py

You could perhaps then run your manage.py command on a cron schedule?

Re: Django Channels Model Binding not sending messages

[Andrew Godwin]

That is odd behaviour - have you tried to see if it's actually the group
send, or something like trying to send it twice? Can you post your binding
configuration?

Re: can't create app in putty

[Jani Tiainen]

Hi,

Looks like you have added "app.app" in your installed apps _before_ 
creating actual app with that name. When trying to form environment for 
executing management command Django fails to find your app.


So either remove that app.app (which seems that it's not even name of 
the app you want to have), create your "webapp" app and after creating 
it add it to settings.py

Hi,

Perhaps you need to set PYTHONPATH to the location where your app module 
is located.

Django Channels Model Binding not sending messages

[Zac Kwan]

In production, I have setup asgi, wsgi and nginx. My javascript frontend 
manage connected successfully base on the logs in runworker. However, when 
a new model is created (DRF API, Admin or Shell), it does not send a 
message to the group where my frontend is connected. It work perfectly in 
runserver.

I had did some testing in the python manage.py shell and found out that it 
work when I try to send a group message myself first.

$ python manage.py shell

Python 3.6.2 (default, Aug 27 2017, 18:32:19) 

[GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)] on darwin

>>> from channels import Group
>>> from github_hook.models import Feed
>>>
>>> Feed.objects.create(name="foo") # Model is created but frontend did not 
receive any message
>>>
>>> Group("news").send({"text": "dsa"}) # After I do this, a print I had in 
consumers.py happened
>>> consumers.py is run!
>>>
>>>  Feed.objects.create(name="foo") # Now when i created a new object, 
frontend successfully received the mssage


The following is my CHANNEL_LAYERS setup:

CHANNEL_LAYERS = {

"CONFIG": {
"hosts": [os.environ.get('REDIS_URL', 
'redis://localhost:6379')],
},
"ROUTING": "github_hook.routing.channel_routing",
},
}


I had been on this for 2 weeks, still caa't figure out what is wrong. Can 
anyone help me figure out whats wrong? 

It seems to me that my application that is served by WSGI, when created a 
model via admin, it does not trigger the message sending. It seems to be 
missing some init on consumers.py?

Django Channels: Model Binding not sending out message to group

[Zac Kwan]

I have nginx, uwsgi and asgi setup correctly. With my javascript frontend, 
it is connected to base on the worker log that contains the demultiplexer 
response. However, when I try to create a model (via API, admin or shell) 
it does not send a message to the worker. In `runserver` all work fine.

So I try creating the model in python manage.py shell.

$ python manage.py shell

Python 3.5.1 (v3.5.1:37a07cee5969, Dec  5 2015, 21:12:44) 

[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

(InteractiveConsole)
>>> from project.models import Feed

>>> from channels import Group

>>>
>>> Feed.objects.create(name="a1") #This does not send a message to my 
frontend
>>>
>>> Group('dsadsa').send({"text": "hi"}) # somehow, after doing this no 
matter which group I send to, it will start working in shell.

>>>
>>> Feed.objects.create(name="a99") #Now when i do this again, it work. My 
frontend receive a message
 


I not really sure what I did wrong or is it a bug with Django Channels. 
There is no logs message about binding message being send out by the worker 
even when I do it successfully in the shell. 

Somehow, I find out that after I try to send a Group message to any group, 
creating the Feed again will sends out the message correctly.

The following is my code for connecting to redis:
CHANNEL_LAYERS = {
   "default": {
   "BACKEND": "asgi_redis.RedisChannelLayer",
   "CONFIG": {
   "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
   },
   "ROUTING": "github_hook.routing.channel_routing",
   },
}

Any kind soul know what is the problem? Am I missing something that's why 
binding does not work in production?
