  • Can't set up image upload in Django

    - by culebrón
    I can't understand what's not working here: 1) settings MEDIA_ROOT = '/var/www/satel/media' MEDIA_URL = 'http://media.satel.culebron' ADMIN_MEDIA_PREFIX = '/media/' 2) models class Photo(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length = 200) desc = models.TextField(max_length = 1000) img = models.ImageField(upload_to = 'upload') 3) access rights: drwxr-xrwx 3 culebron culebron 4.0K 2010-04-14 21:13 media drwxr-xrwx 2 culebron culebron 4.0K 2010-04-14 19:04 upload 4) SQL: CREATE TABLE "photos_photo" ( "id" integer NOT NULL PRIMARY KEY, "name" varchar(200) NOT NULL, "desc" text NOT NULL, "img" varchar(100) NOT NULL ); 4) run Django test server as myself. 5) result: SuspiciousOperation at /admin/photos/author/add/ Attempted access to '/var/www/satel/upload/OpenStreetMap.png' denied. Not a PIL & jpeg issue, seems not to be access rights issue. But what's wrong?

  • Paramiko and Pseudo-tty Allocation

    - by Jon
    I'm trying to use Paramiko to connect to a remote host and execute a number of text file substitutions. i, o, e = client.exec_command("perl -p -i -e 's/" + initial + "/" + replaced + "/g'" + conf); Some of these commands need to be run as sudo, which results in: sudo: sorry, you must have a tty to run sudo I can force pseudo-tty allocation with the -t switch and ssh. Is it possible to do the same thing using paramiko?

  • String formatting named parameters?

    - by Mark
    I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)

  • pyinstaller: 2 instances of my cherrypy app exe get executed.

    - by d.c
    I have a cherrypy app that I've made an exe with pyinstaller. now when I run the exe it loads itself twice into memory. Watching the taskmanager shows the first instance load into about 1k, then a second later a second instance of hte exe loads into about 3k ram. If I close the bigger one both processes die. If I close hte smaller one only that one dies. Loading the exe with subprocess, if I try to proc.kill(), it only kills the small one leaving the other running in memory. Is this a sideeffect of using cherrypy and pyinstaller together?

  • Can I treat IronPython as a Pythonic replacement to C#?

    - by Ewan Nathaniel
    Hey guys! I do understand that this topic has been covered in some way at StackOverflow but I'm still not able to figure out the exact answer: can I treat IronPython as a Pythonic replacement to C#? I use CPython every day, I love the Zen :) but my current task is a Windows-only application with a complex GUI and some other features which I would like to implement using .NET.

  • Posting messages in two RabbitMQ queue, instead of one (using py-amqp)

    - by Khelben
    I've got this strange problem using py-amqp and the Flopsy module. I have written a publisher that sends messages to a RabbitMQ server, and I wanted to be able to send it to a specified queue. On the Flopsy module that is not possible, so I tweaked it adding a parameter and a line to declare the queue on the init_ method of the Publisher object def __init__(self, routing_key=DEFAULT_ROUTING_KEY, exchange=DEFAULT_EXCHANGE, connection=None, delivery_mode=DEFAULT_DELIVERY_MODE, queue=DEFAULT_QUEUE): self.connection = connection or Connection() self.channel = self.connection.connection.channel() self.channel.queue_declare(queue) # ADDED TO SET UP QUEUE self.exchange = exchange self.routing_key = routing_key self.delivery_mode = delivery_mode The channel object is part of the py-amqplib library The problem I've got it's that, even if it's sending the messages to the specified queue, it's ALSO sending the messages to the default queue. AS in this system we expect to send quite a lot of messages, we don't want to stress the system making useless duplicates... I've tried to debug the code and go inside the py-amqplib library, but I'm not able figure out any error or lacking step. Also, I'm not able to find any documentation form py-amqplib outside the code. Any ideas on why is this happening and how to correct it?

  • Simple way to decrease values without making a new attribute?

    - by Jam
    I'm making a program where you're firing a 'blaster', and I have 5 ammo. I'm blasting an alien who has 5 health. At the end I instantiate the player and make him blast 6 times to check that the program works correctly. But the way I've done it makes it so that the amount won't decrease. Is there an easy fix to this, or do I just have to make a new attribute for ammo and health? Here's what I have: class Player(object): """ A player in a shooter game. """ def blast(self, enemy, ammo=5): if ammo>=1: ammo-=1 print "You have blasted the alien." print "You have", ammo, "ammunition left." enemy.die(5) else: print "You are out of ammunition!" class Alien(object): """ An alien in a shooter game. """ def die(self, health=5): if health>=1: health-=1 print "The alien is wounded. He now has", health, "health left." elif health==0: health-=1 print "The alien gasps and says, 'Oh, this is it. This is the big one. \n" \ "Yes, it's getting dark now. Tell my 1.6 million larvae that I loved them... \n" \ "Good-bye, cruel universe.'" else: print "The alien's corpse sits up momentarily and says, 'No need to blast me, I'm dead already!" # main print "\t\tDeath of an Alien\n" hero = Player() invader = Alien() hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) raw_input("\n\nPress the enter key to exit.")

  • To stop returning through SSH using Pexpect

    - by chrissygormley
    Hello, I am trying to use pexpect to ssh into a computer but I do not want to return back to the original computer. The code I have is: #!/usr/bin/python2.6 import pexpect, os def ssh(): # Logs into computer through SSH ssh_newkey = 'Are you sure you want to continue connecting' # my ssh command line p=pexpect.spawn('ssh [email protected]') i=p.expect([ssh_newkey,'password:',pexpect.EOF]) p.sendline("password") i=p.expect('-bash-3.2') print os.getcwd() ssh() This allows me to ssh into the computer but when I run the os.getcwd() the pexpect has returned me to the original computer. You see I want to ssh into another computer and use their environment not drag my environment using pexpect. Can anyone suggest how to get this working or an alternative way. Thanks

  • Django: A Result Specific Numeration for Pagination.

    - by TheLizardKing
    Simply put I want what http://www.reddit.com/ and http://news.ycombinator.com/ have to the left of every link. A numerated link starting with 1 and continuing to the next page by means of pagination. I really enjoy using generic views and their built-in pagination for Django and it seems to allow me access to these values if I was on page 3 with 2 items per page. {'MEDIA_URL': ''} {'LANGUAGES': '<<languages>>', 'LANGUAGE_BIDI': False, 'LANGUAGE_CODE': 'en-us'} {'debug': True, 'sql_queries': '<<sql_queries>>'} {'messages': [], 'perms': <django.core.context_processors.PermWrapper object at 0xadedeec>, 'user': <User: thelizardking>} {'first_on_page': 5, 'has_next': True, 'has_previous': True, 'hits': 7, 'is_paginated': True, 'last_on_page': 6, 'links_list': [<Link: Funky Town>, <Link: Apple Jax>], 'next': 4, 'page': 3, 'page_obj': <Page 3 of 4>, 'page_range': [1, 2, 3, 4], 'pages': 4, 'paginator': <django.core.paginator.Paginator object at 0xadf914c>, 'previous': 2, 'results_per_page': 2} I know there is an add filter for templates but that's as close as I think I can get and that really doesn't do what I want. Am I going to have to use a custom template filter here or is there something I am not seeing?

  • Timing the Linux Kernel boot-time optimisation

    - by CVS-2600Hertz-wordpress-com
    I am trying to optimise the boot-up time of linux on an embedded device (not PC) Currently to profile the boot-up sequence, I have enabled the timing info on printk logs. Is this the most optimum way? If not, how do i profile the boot-up sequence (with timing) with minimum overhead? PS: I have a terminal (of the device) over a serial-connection & I use TeraTerm over windows-XP to access it.

  • Scrapy domain_name for spider

    - by Zeynel
    From the Scrapy tutorial: domain_name: identifies the Spider. It must be unique, that is, you can’t set the same domain name for different Spiders. Does this mean that domain_name must be a valid domain name, like domain_name = 'example.com' Or can I name domain_name = 'ex1' The problem is I had a spider that worked with domain name domain_name = 'whitecase.com' Now I created a new spider as an instance of CrawlSpider and named it domain_name = 'wc2' but I am getting the error "could not find spider for domain "wc2""

  • Android VideoView - Detect point of time in video

    - by Chris
    Hi all, I am using a VideoView to display a video. I am using setOnPreparedListener and setOnCompletionListener to do stuff before and after the video starts and ends. I was wondering how I could go about detecting some point of time in the video. For eg, say I want to write log to a file when the video has played for 10s. How can I detect the 10s mark? Thanks Chris

  • Diophantine Equation

    - by swapnika
    Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n): "Largest number of McNuggets that cannot be bought in exact quantity: n" Hints: Hypothesize possible instances of numbers of McNuggets that cannot be purchased exactly, starting with 1 For each possible instance, called n, 1. Test if there exists non-negative integers a, b, and c, such that 6a+9b+20c = n. (This can be done by looking at all feasible combinations of a, b, and c) 2. If not, n cannot be bought in exact quantity, save n When you have found six consecutive values of n that in fact pass the test of having an exact solution, the last answer that was saved (not the last value of n that had a solution) is the correct answer, since you know by the theorem that any amount larger can also be bought in exact quantity

  • Purpose of Zope Interfaces?

    - by Nikwin
    I have started using Zope interfaces in my code, and as of now, they are really only documentation. I use them to specify what attributes the class should possess, explicitly implement them in the appropriate classes and explicitly check for them where I expect one. This is fine, but I would like them to do more if possible, such as actually verify that the class has implemented the interface, instead of just verifying that I have said that the class implements the interface. I have read the zope wiki a couple of times, but still cannot see much more use for interfaces than what I am currently doing. So, my question is what else can you use these interfaces for, and how do you use them for more.

    Hi Nick! How are you? I'm from Brazil and study at FATEC (college located in Brazil). I'm trying to learn about AppEngine. Now, I'm trying to load a large database from MySQL to AppEngine to perform some queries, but I don't know how i can do it. I did some testing with CSV files,but is there any way to perform the direct import from MySQL? This database is from Pentaho BI Server (www.pentaho.com). Thank you for your attention.
