you know how to pull it down and read it like a webpage?

Ive pulled it down but everthing is in .rst files

hi guys, django (and programming) beginner here. im looking for some resources how to work with authenticated users. once user logs in he should see only content related to him. he should be able to store some data. how to design models/views/templates to handle this? the tutorials i found all deal only with authentication, not what happens after that. could you point me to the right direction? maybe im using wrong keywords to search

svkoskin: It depends on your use case. You may sometimes miss that feature. But you can always define special method for returning all objects in your custom manager.

thank you

finspin, Custom managers and the authentication system are pretty simple.

Jayflux: Sphinx can make html from rst sources.

finspin: It's simply described in docs: https://docs.djangoproject.com/en/1.4/topics/au...

When using DEBUG=True, a page that normally loads in 2-3 seconds, now takes about 20seconds. Profiling the view, I can see most of time is spent in posixpath.py - mainly 'join', 'islink' and 'realpath'. What would cause that?

twoface, Take a look at the sql queries

hu?

django debug toolbar is your friend here

joshuajoshua, the sql queries are no problem - they take about 120ms

in total

twoface: show the debug output, if posixpath is on the top probably heavy template rendering

enable the cached template loader to confirm that

nah

oops, wrong window

apollo13, i do use a number of includes in loops, so that might be it

i'll try with the cached loader

Architekt_: thanks, i've checked that link already. it describes login / logout etc. but i haven't found anything related to users storing data. here is a basic scenario: user logs in to his account, fills a form and saves it. how do i do it in django? as far as i can tell the resource you linked to doesn't describe that. or am i missing something?

finspin, How is that user specific? Do the tutorial.

DO THE TUTORIAL!!!

It will all become within your reach one you do it.

joshuajoshua: you mean the poll tutorial?

Yes

If i have a view thats reusing certain functions and I want DRY, do i just use a class based view?

apollo13, cached template loader made no real difference - deactivating the debug toolbar did, however. i've never had problems with it before :/

twoface: haha, the debug toolbar reads the template files, that might cause a "few" calls ;)

apollo13, a "few" would in this case be about three million :)

that I probably would debug

but turning off debug toolbar and using cached template loaders, i've gone from ~20s to 0.2s

Hello everybody.

I need a HTTP Proxy for Django, to send all the MySQL / PGSQL data through a HTTP Tunnel.

Can someone help me with that please?

wtf?

twoface, Sounds like something was done in a template that should have been done in vanilla Python.

Y3Klo, How is that even django related? Just use an SSH tunnel

joshuajoshua: I can't use SSH tunneling, it must be HTTP...

actually, my previous statement is incorrect - my profile just ate an exception :/

You can tunnel whatever port you want with ssh

Y3Klo: why would one even tunnel db access through http?

I was wondering that.

I love debug toolbar, but it does slow everything right down ;)

kezabelle, Good thing users dont see it.

i'm just surprised that it slows it down this much :/

pfft, i do though

SQL queries and templates + context can easily mean 1-2 seconds to render :(

You alsu use DEBUG=True and the dev server so you lose either way.

apollo13, joshuajoshua: Hard to explain, but it can't be reduced to one word: Firewall (and SHH isn't an option unfortunately)

Y3Klo: well django won't get in your way, writing your own sql backend might get fun though

and I'd rather invest in a sane environment, everything else is just stupid

Y3Klo, firewalls exist for a reason. Why not open a port so that you can actually get work done?

SSH can operate on any port and can tunnel any other port. If you have an open port, SSH will work.

apollo13, joshuajoshua: So, there isn't any solution for that? Beside re-write the SQL Backend of curse.

Or a ten second ssh tunnel, but thats "not and option"

Y3Klo: why would there? it's completly insane from any point of view

Why do you have this firewall restriction?

"Hard to explain", we can't give you a solid answer without knowing anything.

joshuajoshua, apollo13: Once again, I CAN NOT use SHH nor edit the firewall, it's a shared hosting, and no, I can't whitelist the IP 'cause it's coming from Heroku.

ah, the ole "I only spend $5 a year on a core part of my business" defence.

Man up and get a usable server.

joshuajoshua: It isn't not my business, and actually, it isn't even a business... But thanks for your help.

Seriously, why not remove this restriction.

You could just put the DB somewhere else. That's the obvious way to solve this.

Y3Klo: I just think that working around your requirements is way more work than do something else

joshuajoshua, apollo13: It sounds right, it wasn't an requirement (I DO have other places to put the DB too), I'm just curious about this HTTP Tunneling thing and wanted to try&learn.

You can't do anything if the server is not listening on that port and you have no access to the server to reroute firewall ports or tunnel.

If you had access, this would be a single line fix in iptables.

joshuajoshua: Yes, I know about that. The server is located in JustHost, is DOES allow IP whitelisting, the big problem is the cloud platform (Heroku), it doesn't have only 1 IP, and I don't even know the full list of them too.

That's a bad idea, you need to move this somewhere you can actually use it.

You have no tunnel or forward options. Learn sometime later when you actually have the materials to learn it.

joshuajoshua: I've a dedicated server in HostGator, again, I'm just wanting to "try&learn"...

I've succesfully installed a HTTP Tunnel with PHP as Server and Python as client (with an HTTP Proxy), I just came here to ask about django, how easy or hard would be to implement that.

How ould you even use PHP as a proxy? Why not just use the webserver? Either way, both of these options are horribly inefficient when you could just fix it. There's never a good reason to learn how to http proxy DB connections.

why not just use a web server?

That's like asking how to make your car run on hotdogs.

lol

LOL

You could learn, but it would be completely useless information.

Ok, it's a bad (or extremely useless) thing to learn then, thank you guys.

It could be just for fun, short answer is yes it is possible with Django, you're not limited in any way.

tdelam: That why I tried to explain since the beginning, not a big problem neither :)

:)

personally I would make sure that PHP is never installed on a server though

DEF

or mod_python

tdelam: Lol, me neither, but it's already running on the server.

Hell, I like to make sure Apache is never installed on a server.

tsts

gotcha :) that's a good goal to have; remove all dependencies on PHP. I made it mine at this office and it's worked.

Then the question actually is... Why are Apache and PHP used yet!

apollo13: heh, I actually don't mind apache.

er joshuajoshua *

I don't either, but it drives me crazy when I see people proxy info from nginx to apache on the same damn server. Why have another huge blaoted webserver when you've already got a fast light one?

mod_wsgi isn't that great.

hehe
