  • How to set up django-admin.py on windows vista?

    - by shin
    I manage to install Django after some struggles by using setup.py install on Windows Vista Now I tried to use django-admin.py but it is not working. According to this document, http://docs.djangoproject.com/en/dev/ref/django-admin/ The django-admin.py script should be on your system path if you installed Django via its setup.py utility. If it’s not on your path, ... For Windows users, who do not have symlinking functionality available, you can copy django-admin.py to a location on your existing path or edit the PATH settings (under Settings - Control Panel - System - Advanced - Environment...) to point to its installed location. I checked ComputerpropertiesEnvironment Variables, but path to django-admin.py is not in anywhere. So I added C:\Python25\Lib\site-packages\django\bin which is the folder of django-admin.py in User variables for shin Variable PATH, Value C:\Program Files\Google\google_appengine\;C:\Python25\Lib\site-packages\django\bin\ Am I supposed to add to System variables?? But it still does not work. Could anyone tell me how to add the Path in Environment Variables please? Thanks in advance.

  • C++ HTML template framework, templatizing library, HTML generator library

    - by Marcin Gil
    I am looking for template/generator libraries for C++ that are similar to eg. Ruby's Erb, Haml, PHP's Smarty, etc. It would be great if I it would sport some basic features like loops, if/else, int conversion to strings, etc. Parameter passing to template rendering engine is also important if I could pass all of them in a hash map instead of calling some function for each of parameters. Do you have any recommendations? I can see also the possibility of embedding languages like Lua, however I haven't found a templatizing library for that either. Thanks!

  • django-uni-form helpers and CSRF tags over POST

    - by linked
    Hi, I'm using django-uni-forms to display my fields, with a rather rudimentary example straight out of their book. When I render the form fields using <form>{%csrf_tag%} {%form|as_uni_form%}</form>, everything works as expected. However, django-uni-form Helpers allow you to generate the form tag (and other helper-related content) using the following syntax -- {% with form.helper as helper %}{% uni_form form helper%}{%endwith%} -- This creates the <form> tag for me, so there's nowhere to embed my own CSRF_token. When I try to use this syntax, the form renders perfectly, but without a CSRF token, and so submitting the form fails every time. Does anyone have experience with this? Is there an established way to add the token? I much prefer the second syntax, for re-use reasons. Thanks!

  • Azure SDK + Django + Visual Studio 2012 - Publish to Azure succeeds, but I get 500 error

    - by hume
    I followed the instructions here: https://www.windowsazure.com/en-us/develop/python/tutorials/django-with-visual-studio/ However, whenever I try to open the url to my web app in the cloud I get a 500 error. The tutorial doesn't mention setting up the TEMPLATE_DIRS setting in the django application or doing any work on the cloud service machine to install python/django. Could these be the problem?

  • django development IDE

    - by Adam Carr
    I have done a little django development but it has all been in a text editor. I was curious what more advanced development tools others are using in their django development. I am used to using Visual Studio for development and really like the intellisense, code completion, and file organization it provides and would like to find something (or a combination of tools) that would provide some of this in the django/python environment.

  • how to get the type of a deferred template parameter

    - by smerlin
    Is there a way to get the defered type of a class template parameter ? template <class TPtr> struct foo { typedef TPtr ptr_type; typedef ??? element_type; /* shall be the type of a deferred TPtr*/ }; so foo<const char*>::element_type results in const char, and foo<std::vector<int>::iterator_type>::element_type results in int. i am aware of that i can use the value_type typedef for c++ iterators (like std::vector<int>::iterator_type::value_type), but raw pointers havent got a value_type typedef, so i am out of luck there.

  • Template type deduction with a non-copyable class

    - by Evan Teran
    Suppose I have an autolocker class which looks something like this: template <T> class autolocker { public: autolocker(T *l) : lock(l) { lock->lock(); } ~autolocker() { lock->unlock(); } private: autolocker(const autolocker&); autolocker& operator=(const autolocker&); private: T *lock; } Obviously the goal is to be able to use this autolocker with anything that has a lock/unlock method without resorting to virtual functions. Currently, it's simple enough to use like this: autolocker<some_lock_t> lock(&my_lock); // my_lock is of type "some_lock_t" but it is illegal to do: autolocker lock(&my_lock); // this would be ideal Is there anyway to get template type deduction to play nice with this (keep in my autolocker is non-copyable). Or is it just easiest to just specify the type?

  • Django: Paginator + raw SQL query

    - by Silver Light
    Hello! I'm using Django Paginator everywhere on my website and even wrote a special template tag, to make it more convenient. But now I got to a state, where I need to make a complex custom raw SQL query, that without a LIMIT will return about 100K records. How can I use Django Pagintor with custom query? Simplified example of my problem: My model: class PersonManager(models.Manager): def complicated_list(self): from django.db import connection #Real query is much more complex cursor.execute("""SELECT * FROM `myapp_person`"""); result_list = [] for row in cursor.fetchall(): result_list.append(row[0]); return result_list class Person(models.Model): name = models.CharField(max_length=255); surname = models.CharField(max_length=255); age = models.IntegerField(); objects = PersonManager(); The way I use pagintation with Django ORM: all_objects = Person.objects.all(); paginator = Paginator(all_objects, 10); try: page = int(request.GET.get('page', '1')) except ValueError: page = 1 try: persons = paginator.page(page) except (EmptyPage, InvalidPage): persons = paginator.page(paginator.num_pages) This way, Django get very smart, and adds LIMIT to a query when executing it. But when I use custom manager: all_objects = Person.objects.complicated_list(); all data is selected, and only then python list is sliced, which is VERY slow. How can I make my custom manager behave similar like built in one?

  • Django 1.2 crash course needed

    - by delusionalweekendwarrior
    I know Python but I've never used Django. What do I need to know about Django 1.2 to port my typical PHP CRUD web application in one weekend? (Yes I've read Joel Spolsky's Netscape article :-)) I'm reading this tutorial right now and it's excellent. I'm already playing around with inspectdb to generate my models from the existing schema. I'm planning to use the following features of Django this weekend: Fragment caching Static asset versioning (for far future expires) Schema migrations (or whatever they're called in Django) Auto-admin (and customize it later) The test framework ...other stuff I probably don't know about yet I'm familiar with all these concepts in other languages/frameworks, except for the ORM which I've never used. I know SQL pretty well though. Any links, sage bits of advice, gotchas, stuff not mentioned in the (excellent) tutorial/docs, or stuff that is mentioned but warrants repeating == very welcome. Thanks!

  • Django-admin.py not being recognized suddenly

    - by Jen Camara
    I tried starting a new Django project yesterday but when I did "django-admin.py startproject projectname" I got an error stating: "django-admin.py is not recognized as an internal or external command." The strange thing is, when I first installed Django, I made a few projects and everything worked fine. But now after going back a few months later it has suddenly stopped working. I've tried looking around for an answer and all I could find is that this typically has to do with the system path settings, however, I know that I have the proper paths set up so I don't understand what's happening. Does anybody have any idea what's going on?

  • Puzzle - Dynamically change data template control from another data template

    - by Burt
    I have a DataTemplate that contains an Expander with a border in the header. I want the header border to have round corners when collapsed and straight bottom corners when expanded. What would best practice be for achieving this (bonus points for code samples as I am new to XAML)? This is the template that holds the expander: <DataTemplate x:Key="A"> <StackPanel> <Expander Name="ProjectExpander" Header="{Binding .}" HeaderTemplate="{StaticResource B}" > <StackPanel> <Border CornerRadius="0,0,2,2"> This is the expander datatemplate: <DataTemplate x:Key="B"> <Border x:Name="ProjectExpanderHeader" CornerRadius="{Binding local:ItemUserControl.ProjectHeaderBorderRadius, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContentPresenter}}}" Background="{StaticResource ItemGradient}" HorizontalAlignment="{Binding HorizontalAlignment, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContentPresenter}}, Mode=OneWayToSource}"> <local:ItemContentsUserControl Height="30"/> </Border> </DataTemplate>

  • Get the path to Django itself

    - by andybak
    I've got some code that runs on every (nearly) every admin request but doesn't have access to the 'request' object. I need to find the path to Django installation. I could do: import django django_path = django.__file__ but that seems rather wasteful in the middle of a request. Does putting the import at the start of the module waste memory? I'm fairly sure I'm missing an obvious trick here.

  • C++: Template functor cannot deduce reference type

    - by maciekp
    I've got a functor f, which takes a function func and a parameter t of the same type as func. I cannot pass g to f because of compilation error (no matching function for call to f(int&, void (&)(int&)) ). If g would take non-reference parameter g(int s), compilation finishes. Or if I manually specify template parameter f(i, g), compilation also finishes. template<typename T> void f(T t, void (*func)(T)) {} void g(int& s) {} int main(int, char*[]) { int i = 7; f(i, g); // compilation error here return 0; } How can I get deduction to work?

  • Codeigniter Template library, add_js() method

    - by Karl
    using This Template Library when i try and use the add_js() function it errors out. I add the regions $_scripts to the template header file but when i load the page it says undefined variable _scripts. any thoughts? changed <?= $_scripts ?> to <?= (isset($_scripts)) ? $_scripts : “”; ?> and obviously i lose the error but the js file still isnt loading. I did an echo at each step though the add_js() method and the output is correct. I also did an output of $this-js and they both had the corret output. So it gets through the get_js method fine and sets the class variable fine but i dont get anything added to the actual page.

  • Problems with i18n using django translation on App-Engine with Korean and Hindi

    - by Greg
    I've got a setup based on the post here, and it works perfectly. Adding more languages to the mix, it recognises them fine, except for Korean (ko) and Hindi (hi). Chinese/Japanese/Hebrew are all fine, so nothing to do with encodings/charsets I don't think. Taking a look into the django code inside the app-engine SDK, I notice that all the languages that I'm using except for ko and hi are ones that ship with django - in the default settings.py and inside the locale folder they are missing. If I copy one of the locale folders inside the /usr/local/google_appengine/lib/django[...]/conf/locale and rename it to be 'ko', then it starts working in my app, but I won't be able to replicate this modification when I deploy to app-engine, so need a bit of help understanding what I might be doing wrong. my settings.py is definitely being taken into account, as if I remove languages from there then they stop working (as they should). If I copied the django modules into my app, under 'lib' there say, could I use those instead of the ones app-engine tries to use, maybe? I'm brand new to python/django/app-engine, and developing on a Mac with Leopard, if that makes any difference. I have the latest app-engine SDK as of tuesday.

  • C++ template parameter/class ambiguity

    - by aaa
    hello. while testing with different version of g++, the following problem came up template<class bra> struct Transform<bra, void> : kernel::Eri::Transform::bra { static const size_t ni = bra::A::size; bra::A is interpreted as kernel::Eri::Transform::bra::A, rather than template argument by g++ 4.1.2. on the other hand, g++ 4.3 gets it right. what should be correct behavior according to standard? Meanwhile, I refactor slightly to make problem go away.

What would be the best way to handle login, session management and user authentication? I do not want to use the in-built Django user management. I am using Django very sparingly(URLs, templates)

  • Django template context not working with imported class

    - by Andy Hume
    I'm using Django's templating on appengine, and am having a problem whereby a class I'm importing from another package is not correctly being made available to the template context. Broadly speaking, this is the code. The prop1 is not available in the template in the first example below, but is in the second. MyClass is identical in both cases. This does not work: from module import MyClass context = MyClass() self.response.out.write(template.render(path, context)) This does: class MyClass(object): def __init__(self): self.prop1 = "prop1" context = MyClass() self.response.out.write(template.render(path, context)) If I log the context in the above code I get: <module.MyClass object at 0x107b1e450> when it's imported, and: <__main__.MyClass object at 0x103759390> when it's defined in the same file. Any clues as to what might cause this kind of behaviour?

  • FastCGI has to be restarted for new content to be displayed on my Django site

    - by vorpyg
    I'm currently testing serving my Django site with Nginx, FastCGI and Flup. The server is configured roughly as described in the Django Advent article. I had to do some minor modifications in order to make it work in Ubuntu 9.10. The problem is that when I add new content it doesn't show up on the page before I restart the FastCGI process. I haven't enabled any caching functionality in Django, and when I query the DB from the Django shell it works as expected. Anybody got ideas to what's causing this?
