Question - sound files and Django.
All, I have a question for the list. I am thinking about making a small website for a friend - a singer/songwriter - that will allow him to embed soundfiles for download and/or streaming by others. I'd like to provide a nice "admin" interface for him so that he can upload his mp3s (or similar) when he feels like it. Naturally, I thought of Django. :-) To this end, I am interested in finding out if anyone has created a "SoundField" class for Django to store and stream sound files - analogous to how the "ImageField" class allows Django to store and display image files. I would also like to know if there are ready made template tags for sound files. Has anyone tackled this? As someone said, I would rather not re-invent the wheel. (And if it hasn't been tackled, well, I better get cracking on it.) Cheers, Peter --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Joakin, If your editor can handle utf-8, then perhaps use the utf-8 encoding: #!/usr/bin/python #-*- coding: UTF-8 -*- Another pitfall you might have is that you are using the str rather than the unicode type. Don't forget to declare your string constants with a u in front. For example: problem_child = u"å". I hope this helps.

Re: dumping data in utf-8
Andreo:
Technically, it is utf-8. I am guessing that you want to see actual
Cyrillic characters, rather than escape sequence equivalents.
The behavior you are seeing is due to PyYAML, the parser used by
Django for YAML fixtures. By default, it produces YAML with Unicode
escape sequences - a little irritating to those from non-ASCII
environments. This isn't a issue with PyYAML - this is an issue with
how Django calls it.
For the time being, you could try this code with all YAML produced:
import yaml;
stream = file("fixture_with_undesirable_escaping.yaml", "r");
Loaded = yaml.load(stream);
otherstream = file("fixture_with_lovely_ukrainian_characters.yaml",
"w");
yaml.dump(Loaded, otherstream, allow_unicode=True);
This gets you something like:
- fields: {description: 'Украи́на (укр. Україна[ukrɑˈ'}
Which is what you want.
Best regards,
Peter

I got this link from Homakov's github complaint[1]. http://enlightsolutions.com/articles/whats-new-in-edge-scoped-mass-assignment-in-rails-3-1 "If you’re using Rails and you want to be secure, you should be protecting against mass assignment. Basically, without declaring attr_accessible or attr_protected, malicious users can set any column value in your database, including foreign keys and secure data." Huh? (With a side helping of jaw dropping.) Why would you allow your users to get anywhere near the DB code? Why should it be even possible? Why would "magic" attributes make a difference? In Django, you abstract the models code (which reads and writes DB records) from the views (where all the monkey business could occur) from the urls. At least that's what I thought you should do. You also make the views in charge of checking whether your requests are POSTs or GETs. Okay, this depends on the programmer to do the right thing, but programmers are encouraged to do the right thing by the framework. You could set up a vulnerability that allows attackers to add every British PM in your Users model (from Walpole to Cameron) via a GET request. But you'd have to sabotage your own code to do so.

Python FAQ: Webdev
All, This may be a link of interest to the list. The site "Fuzzy Notepad" recently wrote an article absolutely, absolutely slating PHP [*]. So the question was asked: "I only know PHP. How do I write a Web application in Python? "This is a deeply complex question. I could easily fill a book on web development and Python and how to make the two interact, so I was hoping to put this one off for a while. But given that I just trashed PHP rather harshly, it seems prudent to answer it sooner rather than later..." http://me.veekun.com/blog/2012/05/05/python-faq-webdev/ The site recommends "Flask" by the way - not Django. The author thinks it is too heavyweight for his or her uses. But there seems to be a lot of ideas in the article about how to make a framework that seem to be captured in Django.

"Where does Django fit in"? It fits in on the server machine. A HTTP server program (like Apache or nginx) takes web page requests, and passes them onto Django. In turn, Django interprets the requests, generally running queries on the database and doing whatever processing is necessary to generate a web page. Django then throws the generated web page to the HTTP server, which then sends it back to the web browser. Django has a development server where you can request and receive pages without something like Apache or nginx. But this is not recommended in a production environment, because it is a lot slower. Django is used for generating content dynamically; but there is no gain in using development server to fetch static files (like images). > Q: There are simple websites which just serves static contents and other > site which deals with forms and data base.

All you need is your favorite HTTP server. But if you are dealing with forms and databases, then Django is very, very suitable indeed. There are classes in the framework that allow you to create forms on the fly. As for databases, there are also classes that allow you to model the database tables and run queries _without writing any SQL_. Do you really want to write your own SQL statements? I don't. You asked "are there some other modules which needs to be used?" Well, you need Python to run it; Django won't work without it. But other "modules" you may need are modules written in Python - and they can be installed as simply as running "pip install " from the command line. One of the best things about Django is that a lot of security is built in by default. You can write something and be fairly confident that all the attack vectors have been blocked off. SQL injections? Not a problem; the model classes do all the hard work of passing queries to the database and _escaping content_. Cross Site Request Forgeries? The form classes prevent such things occurring. > Q: Is Django a substitute to CGI for dynamic web generation. > > It sounds better than bog standard CGI, where every request spawns a new process. > Q: Can i use Django for development of a full fledged website. > > > Of course you can.

Re: Looking for recomendation on using popup like admin "+" widget
GKR, If I understand you correctly, you want to override the behavior of a Field.choices property, so that admins can add values on the fly. I don't think that is possible with Django. Maybe the best solution is to create a new table with one column - one that contains only the choices admins want for particular fields in a parent model. And then use the magic of InlineModelAdmin objects to embed that table in the parent tables's admin page. https://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-objects Is this of assistance?

Coulson, That's probably the best advice you are going to get. You're going to have to do it yourself - dive into HTML and get cracking. This list is about Django, a Web framework written in Python. You're question is so broad that it sounds like you're asking people to _design_ the whole website for you. That may not be what you intended to convey, but that's what it feels like. If you intent to do your website through Django, please try to research it as much as possible yourself. Then if your come across an issue than you can't resolve, please have a read of this before replying to the list: http://www.mikeash.com/getting_answers.html I'd also give some personal advice. It's harder to understand people when they leave out punctuation. Periods and commas make your meaning more clear, which makes other people more able to help you.

I think you've identified the problem. You have
'question.views.details' as your view function, but you haven't
supplied the source for it. Which I believe means you _have_ to write
it, and the template that goes with it.
One thing I would add: from a user-friendliness point of view, it
might be better to have the questions in one page, or at most 5.
Hitting "Next" 21 times is a turn off for most people. But you know
your needs best.
Best regards,
Peter

Re: WindowsError 32
Domdom, The first thing to do is Google|Bing|Other Search Engine of your choice "WindowsError 32". If you had done that, the first link: http://msdn.microsoft.com/en-us/library/ms681382%28v=vs.85%29.aspx Would have given you a clue: ERROR_SHARING_VIOLATION 32 (0x20): The process cannot access the file because it is being used by another process.

Re: Django for a front end designer
If you are thinking about diving into PHP, I suggest you read this first: http://www.tbray.org/ongoing/When/200x/2006/02/17/PHP It's five years old, but it contains a lot of links to pro- and anti- PHP rants, which you should consider. (Consider also that there's no good Unicode support inside PHP even after this time.) Personally, reading it was enough for me to dive into Python instead. But you may feel differently. Another thing you should consider: sometimes programming languages such as Python can be used for web-related things that aren't just running a web server. Take screen-scraping: taking an existing website of a client, and extracting its content for your use. There are libraries available with Python like BeautifulSoup that allow you to handle malformed HTML and scrape it into what ever file format you want. Then you can use Django's admin functionality to load the file into your database, making a new Django-powered website for your client! How would you screen-scrape in PHP? Is it even possible? Before reading the Django tutorial, read the Python tutorial, and see if the language is right for you or not: http://docs.python.org/tutorial/ Whatever your decision, good luck!
