I'm using sqlite and I found there is virtual tables with Levenstein score

max3: but yeah for eg if you use docker, redis is not too much to maintain

like why isn't there just something like green threads

_mirak_: Plan on using sqlite in production? I'd suggest postgres, if you can.

schinckel: sqlite is enough

There's some really nice full-text-searching stuff in postgres, that some clever cloggs have made work with Django.

i don't have any need for ordering, or coherency, or even response. i just need to a task to be done asynchronously. why is there no way to do this in python

schinckel: I can move to postgress easily if it solves the proplem

Well, the short answer is processes that are handling HTTP requests shouldn't also be doing other thigns.

one thread one function sure

_mirak_: Have a look at the FTS stuff, and see if that meets your needs.

yeah actually postgres has gist an gin indexes that are pretty cool for fulltext search

i don't agree one process one function

_mirak_: https://docs.djangoproject.com/en/1.11/ref/cont...

Doesn't look like there is such feature for postgres out of the box

There are several.

mattmcc: Can you point please?

For just string similarity, https://www.postgresql.org/docs/current/static/...

https://www.postgresql.org/docs/current/static/... is an extension (distributed by default, just needs to be enabled) with more robust functionality, and it can use indexes.

mattmcc, i guess i can use the ipc backend?

I'm probably the wrong one to ask, I haven't used channels yet myself.

and channels 2.0 is fast approaching! :)

what does 2.0 promise?

Ponies?

always ponies :)

more efficient single-process solution, for a start, iirc

okay fine: rabbitmq or redis?

well i don't want to run django as a single process in production of course

Hello, I have password_change/done url, and I don't want the user be able to see that page by typing the url. Just when he changes his/her password. Do you know what should I do?

In other words, I want it to be accessible to internally.

mojtaba, you mean you want a confirmation page?

max3: Yes

why does it matter to you if people can see it before then?

no one is going to navigate to that url for fun

and even if they do why does it matter?

also you could just make your response that template instead of it being a url

max3: Just wanted to look more professional

*that template serialized

max3: Could you please explain more.

response.write("<p>Here's the text of the Web page.</p>")

max3: thanks

mattmcc: wouldn't it better to use haystack in the case?

_mirak_: Depends on your needs. Haystack itself isn't an FTS it just abstracts them.

max3: I am using builtin auth view, PasswordChangeDoneView. So it seems I can not use HttpResponse

mojtaba, just subclass it or something

max3: subclass it in the passwordChange class?

i don't know what you mean

mojtaba, class mypasswordchangeclass(PasswordChangeDoneView): def get(...): super(mypasswordchangeclass, self).get(...)

max3: How about checking 'HTTP_REFERER'?

checking where/when?

When the user navigates to the confirmation page, if the previous page is not the form to change password, it is not allowed. If it is, it will go through.

mattmcc: in a nutshell I need to filter results from my parser, if there is a similar text it should not be written into db

mojtaba, what do you mean go through? but anyway i recommend you don't use http_referer since it can be spoofed

max3: I meant to show them the confirmation message.

yes i understand what you meant and i still think what i said

max3: Thanks, I will try to implement your method

max3: So when do people use http_referer?

mojtaba, good question. i don't know

max3: :)

Hi all

hi

I have a model with the following field definition "has_been_synced = models.BooleanField(default=True)"

I'm using Postgres

ok

When I check the table definition, the default value isn't being set

correct

Checking the docs, I can't seem to find how to set a default value

Django doesn't send those defaults to the schema, just uses them in models

there was another discussion about this recently... the big problem is knowing the state of the DB record after an INSERT

Is there way to do this without having to touch the table after performing the migration?

I have a similiar issue with a datetimefield where I want the default value to be now()

again

django doesn't do this

the default you specify on model fields is NOT recorded in the DB schema

it's only used in the model code

and I just explained the main reason for this

Understood; so there is no way to enforce this with Django?

sure.. it's enforced... in your models

is there an actual problem you're having?

Coming from previous projects, I have a bad habit of bypassing frameworks to achieve results

Since I'm starting a new project, I'm trying to avoid this and use Django as it was designed to be used

well, then, stop planning on bypassing it :)

With this particular project, I have a weather sensor where I retrieve the data over a serial link, then save it to a database

simple enough

It's pretty straightforward for the most part

Actually, going into this in a little more detail

I have a script that runs on an RPi that retrieves the current values from the weather station

I can then either A) send the data using JSON over a TCP/IP connection to a script running on the server and write the data to the database

Or B) have RPI do a GET or POST to Django (also running on the server)

might as well blend both, and POST JSON data to Django over a TCP link :)

Heh!

Being a bit of an experiment, I used Django to create the model to log the weather data (with previous project, the database was already defined and Django had to be made aware of the existing database)

I have a question about Django's logging (or python logging in general I guess). So when I define this: https://dpaste.de/r1J4 on my project settings, does "django" logger override the existing default "django" logger? and the rest default loggers will work?

What I'm trying to do, is to have the existing default Django LOGGING but without mailing to the admins feature.

does defining "django" logger effectively overrides the default "django" logger?

or are they stacked?

any chance that there is a postgres database layer that uses https://github.com/MagicStack/asyncpg

I want to use the django orm asyncronously
