  • safely hosting a django project over apache using centos

    - by tipu
    Error can be seen at: http://djaffry.selfip.com:8080/ I had a project working great, but I had all the files under /var/www/ and with my limited understanding it's bad, according to django's site: "If your background is in PHP, you’re probably used to putting code under the Web server’s document root (in a place such as /var/www). With Django, you don’t do that. It’s not a good idea to put any of this Python code within your Web server’s document root, because it risks the possibility that people may be able to view your code over the Web. That’s not good for security. Put your code in some directory outside of the document root, such as /home/mycode." So I went to /home/tipu/stuff/ and executed django-admin.py startproject twingle. Then I went to apache and did <VirtualHost *:8080> ServerName tweet_search_engine DocumentRoot /home/tipu/stuff/twingle/ </VirtualHost> <Directory /home/tipu/stuff/twingle> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE settings PythonOption django.root /home/tipu/stuff/twingle PythonDebug On PythonPath "['/home/tipu/stuff/', '/home/tipu/stuff/twingle/'] + sys.path" </Directory> Now I am getting a 403 Forbidden error.. any idea what I'm doing wrong? I'm newer to Linux (CentOS) and django, so I could be over looking some very simple things.

  • eclipse django using wrong settings.py in pythonpath

    - by user1290264
    I have pydev/django installed in eclipse, and it runs fine. However, after adding a second django project to eclipse and running the server ('http://127.0.0.1:8000') the pythonpath seems to be stuck on project2 even when I run project1. As a summary, I have two django projects: project1, project2. When I run the django server for project1 I get: Validating models... 0 errors found Django version 1.5, using settings 'project1.settings' Development server is running at 'http://127.0.0.1:8000/' Quit the server with CTRL-BREAK. The above seems to suggest that django is using the correct settings file; however, when I go to 'http://127.0.0.1:8000/' it displays the urls from project2. Also, if I go to 'http://127.0.0.1:8000/admin' the models are getting pulled from the sqlite.db file in project2 as well. I've even tried removing project2 from eclipse entirely and now at 'http://127.0.0.1:8000/admin' I get this error: Python Path: ['C:\Users\Brad\workspaces\In Progress\project2', 'C:\Users\Brad\workspaces\In Progress\project2', 'C:\Python27\DLLs', 'C:\Python27\lib', 'C:\Python27\lib\plat-win', 'C:\Python27\lib\lib-tk', 'C:\Python27', 'C:\Python27\lib\site-packages', 'C:\Windows\system32\python27.zip'] If I run the server on a different port with project1 the path seems to be fine: runserver 7000 --noreload Then 'http://127.0.0.1:7000/' uses project1's paths, but it doesn't seem like I should have to do this. Note: I have setup the run configurations as correctly as I know how. In the main tab, the project and main module both point to the correct project (project1), and the "PYTHONPATH that will be used in the run:" includes project1. Also, I have cleared my browser history, cookies, and everything that chrome would let me delete.

  • Use Django ORM as standalone [closed]

    - by KeyboardInterrupt
    Possible Duplicates: Use only some parts of Django? Using only the DB part of Django I want to use the Django ORM as standalone. Despite an hour of searching Google, I'm still left with several questions: Does it require me to set up my Python project with a setting.py, /myApp/ directory, and modules.py file? Can I create a new models.py and run syncdb to have it automatically setup the tables and relationships or can I only use models from existing Django projects? There seems to be a lot of questions regarding PYTHONPATH. If you're not calling existing models is this needed? I guess the easiest thing would be for someone to just post a basic template or walkthrough of the process, clarifying the organization of the files e.g.: db/ __init__.py settings.py myScript.py orm/ __init__.py models.py And the basic essentials: # settings.py from django.conf import settings settings.configure( DATABASE_ENGINE = "postgresql_psycopg2", DATABASE_HOST = "localhost", DATABASE_NAME = "dbName", DATABASE_USER = "user", DATABASE_PASSWORD = "pass", DATABASE_PORT = "5432" ) # orm/models.py # ... # myScript.py # import models.. And whether you need to run something like: django-admin.py inspectdb ... (Oh, I'm running Windows if that changes anything regarding command-line arguments.).

  • Macports and virtualenv site-packages Fallback

    - by Streeter
    I've installed django and python as this link suggested with macports. However, I'd like to use virtualenv to install more packages. My understanding is that if I do not pass in the --no-site-packages to virtualenv, I should get the currently installed packages in addition to whatever packages I install into the virtual environment. Is this correct? As an example, I've installed django through macports and then create a virtual environment, but I cannot import django from within that virtual environment: [streeter@mordecai]:~$ mkvirtualenv django-test New python executable in django-test/bin/python Installing setuptools............done. ... (django-test)[streeter@mordecai]:~$ pip install django-debug-toolbar Downloading/unpacking django-debug-toolbar Downloading django-debug-toolbar-0.8.4.tar.gz (80Kb): 80Kb downloaded Running setup.py egg_info for package django-debug-toolbar Installing collected packages: django-debug-toolbar Running setup.py install for django-debug-toolbar Successfully installed django-debug-toolbar Cleaning up... (django-test)[streeter@mordecai]:~$ python Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import django Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named django >>> So I can install packages into the virtual environment, but it isn't picking up the global site-packages. Or am I not doing something correctly / missing something / misunderstanding how virtualenv works? I've got Mac OS 10.6 (Snow Leopard), have updated my macports packages and am using macports' python26 (via python_select python26).

  • Django + GAE (Google App Engine) : most convenient path for a beginner?

    - by mac
    Some background info first: Goal: a medium-level complexity web app that I will need to maintain and possibly extend for a few years. Experience: good knowledge of python, some experience of MVC frameworks (in PHP). Desiderata: using django and google app engine. I read extensively about the compatibility issues between GAE and Django, and I am aware of the GAE patch, the norel project, and other similar pieces of code. I have also understood that the SDK provides some of the features of django "out of the box". Yet, given that I have no previous experience with neither Django nor GAE, I am unable to evaluate to which extent using a patched version of Django will strip away important features, or how far the framework provided in the SDK is compatible with Django. So I am rather confused on what would be the best way to proceed in my situation: Should I simply use a patched version of Django as the differences with the original Django are so minor that I would hardly notice them? Should I write my app completely in "regular django" and try to port it to GAE only afterwards, when I will have got a grasp on Django internals and philosophy? Should I write my app using the framework provided with the SDK and port it to django only afterwards? Should I... ? Thank you in advance for your time and advice.

  • Potential Django Bug In QuerySet.query?

    - by Mike
    Disclaimer: I'm still learning Django, so I might be missing something here, but I can't see what it would be... I'm running Python 2.6.1 and Django 1.2.1. (InteractiveConsole) >>> from myproject.myapp.models import * >>> qs = Identifier.objects.filter(Q(key="a") | Q(key="b")) >>> print qs.query SELECT `app_identifier`.`id`, `app_identifier`.`user_id`, `app_identifier`.`key`, `app_identifier`.`value` FROM `app_identifier` WHERE (`app_identifier`.`key` = a OR `app_identifier`.`key` = b ) >>> Notice that it doesn't put quotes around "a" or "b"! Now, I've determined that the query executes fine. So, in reality, it must be doing so. But, it's pretty annoying that printing out the query prints it wrong. Especially if I did something like this... >>> qs = Identifier.objects.filter(Q(key=") AND") | Q(key="\"x\"); DROP TABLE `app_identifier`")) >>> print qs.query SELECT `app_identifier`.`id`, `app_identifier`.`user_id`, `app_identifier`.`key`, `app_identifier`.`value` FROM `app_identifier` WHERE (`app_identifier`.`key` = ) AND OR `app_identifier`.`key` = "x"); DROP TABLE `app_identifier` ) >>> Which, as you can see, not only creates completely malformed SQL code, but also has the seeds of a SQL injection attack. Now, obviously this wouldn't actually work, for quite a number of reasons (1. The syntax is all wrong, intentionally, to show the oddity of Django's behavior. 2. Django won't actually execute the query like this, it will actually put quotes and slashes and all that in there like it's supposed to). But, this really makes debugging confusing, and it makes me wonder if something's gone wrong with my Django installation. Does this happen for you? If so/not, what version of Python and Django do you have? Any thoughts?

  • [WordPress] Hide Custom Fields in New Post?

    - by Norbert
    I just started out with WordPress and I'm having some problems with the custom fields.

Is there any way to hide the fields to only show the "Add new custom field:" part? Thank you!

  • Django pagination | get current index of paginated item in page index, (not the page index range its

    - by cka
    I am trying to build a photo gallery with Django. It is set up by category. I have paginated the results of a category by n amount of images per page. I want to also use the paginator on the page that shows just the single image and have a prev/next button for the prev/next image in that category. My thought was to get the current index for the image itself and have that be the link to the /category/CUR_IMG_ID_PAGINATION_LIST/ as the result of paginating the entire set would yield the same index as the current image index in the paginated results. For instance if the image i want is image 45 out of 150 images total for a category, then when i paginate the 150 images the 45 will be the actual number of the page I want. If there's an easier way to do this, let me know. Django 1.1

  • How do I properly unit test a Django session?

    - by thebossman
    The behavior of Django sessions changes between "standard" views code and test code, making it unclear how test code is written for sessions. Googling this yields two relevant discussions about this issue: Easier manipulation of sessions by test client test.Client.session.save() raises error for anonymous users I'm confused because both tickets have different ways of dealing with this problem and they were both Accepted. I assume this means they were patched and the behavior is now different. I also don't know to which versions these patches would pertain. If I'm writing a unit test in Django 1.0, how would I set up my session store for sessions to work as they do in the browser?

  • How do I automatically rebuild the Sphinx index under django-sphinx?

    - by Apreche
    I just setup django-sphinx, and it is working beautifully. I am now able to search my model and get amazing results. The one problem is that I have to build the index by hand using the indexer command. That means every time I add new content, I have to manually hit the command line to rebuild the search index. That is just not acceptable. I could make a cron job that automatically runs the indexer command every so often, but that's far from optimal. New data won't be indexed until the cron runs again. In addition, the indexer will run unnecessarily most times as my site doesn't have data being added very often. How do I set it up so that the Sphinx index will automatically rebuild itself whenever data is added to or modified in a searchable django model?

  • Problem getting started with GeoDjango

    - by akv
    As soon as I add "from django.contrib.gis.db import models" instead of "from django.db import models", Django stops recognizing the app and gives this error: Error: App with label location could not be found. Are you sure your INSTALLED_APPS setting is correct? The error goes away as soon as I comment out "from django.contrib.gis.db import models"... I have added "django.contrib.gis" and the "location" app to the INSTALLED_APPS setting correctly. Any clues why this is happening? I am running using Django v1.1.1 final, on my windows laptop.

  • PHP: Type hints for fields with Eclipse PDT

    - by Silvio Donnini
    Using Eclipse + PDT, I know that you can specify the return type of a method or the type of a variable within a method via type hints. How about class fields? Can I declare the type of a field in order to enable autocompletion for that variable? I tried something on the lines of: class MyClass { protected $Field; /* @var $Field MyType */ ... but it doesn't work. Is there a way to achieve autocompletion of class fields with Eclipse and PDT? thanks, Silvio

  • How to extend the comments framework (django) by removing unnecesary fields?

    - by Ignacio
    Hi, I've been reading on the django docs about the comments framework and how to customize it (http://docs.djangoproject.com/en/1.1/ref/contrib/comments/custom/) In that page, it shows how to add new fields to a form. But what I want to do is to remove unnecesary fields, like URL, email (amongst other minor mods.) On that same doc page it says the way to go is to extend my custom comments class from BaseCommentAbstractModel, but that's pretty much it, I've come so far and now I'm at a loss. I couldn't find anything on this specific aspect.

  • Can I suppress newlines after each template tag with Django's template engine?

    - by ento
    In Rails ERB, you can suppress newlines by adding a trailing hyphen to tags: <ul> <% for @item in @items -%> <li><%= @item %></li> <% end -%> </ul> becomes: <ul> <li>apple</li> <li>banana</li> <li>cacao</li> </ul> Is there a way to do this in Django? (Disclosure: I'm generating a csv file with Django) Edit: Clarified that the newlines I'm hunting down are the ones left behind after the template tags.

  • Can we represent bit fields in JSON/BSON?

    - by zubair
    We have a dozen simulators talking to each other on UDP. The interface definition is managed in a database. The simulators are written using different languages; mostly C++, some in Java and C#. Currently, when systems engineer makes changes in the interface definition database, simulator developers manually update the communication data structures in their code. The data is mostly 2-5 bytes with bit fields for each signal. What I want to do is to generate one file from interface definition database describing byte and bit field definitions and let each developer add it to his simulator code with minimal fuss. I looked at JSON/BSON but couldn't find a way to represent bit fields in it. Thanks Zubair

  • Will Django user permissions work for models with inline tabular forms of other models?

    - by stinkypyper
    I am setting up DJango admin to make a model editable. On the same page I have tabular inline of a child model. Everything works as expected. Now I want to restrict permission on the tabular inline child form. Specifically remove update and delete permissions on it. I have tried removing the permissions for the admin user using the 'user permissions' of that user. However, it does not work. Does DJango respect the user permissions in regards to inline model forms?

  • Could not import Django settings into Google App Engine

    Lets say that we are getting POSTed a form like this in Django: rate=10 items= [23,12,31,52,83,34] The items are primary keys of an Item model. I have a bunch of business logic that will run and create more items based on this data, the results of some db lookups, and some business logic. I want to put that logic into a save signal or an overridden Model.save() method of another model (let's call it Inventory). The business logic will run when I create a new Inventory object using this form data. Inventory will look like this: class Inventory(models.Model): picked_items = models.ManyToManyField(Item, related_name="items_picked_set") calculated_items = models.ManyToManyField(Item, related_name="items_calculated_set") rate = models.DecimalField() ... other fields here ... New calculated_items will be created based on the passed in items which will be stored as picked_items. My question is this: is it better for the save() method on this model to accept: the request object (I don't really like this coupling) the form data as arguments or kwargs (a list of primary keys and the other form fields) a list of Items (The caller form or view will lookup the list of Items and create a list as well as pass in the other form fields) some other approach? I know this is a bit subjective, but I was wondering what the general idea is. I've looked through a lot of code but I'm having a hard time finding a pattern I like.

  • how to bind input fields to a modal input fields AngularJS

    - by user3919120
    I have a form with a Customer and its properties populating input fields. If the user needs to change the Customer they click on the CustomerName input. A modal opens with a Customer List for them to choose from. There selection populates the input fields in that modal. I need to have that new information put in the already populated input fields. plunkr <div class="form-group"> <div class="input-group"> <span class="input-group-addon">C. Name</span> <input style="width:400px" ng-model="currentItem.CustomerName" class="form-control btn btn-default" ng-click="editJobCustomerModal()" /> </div> </div> <div class="form-group"> <div class="input-group"> <span class="input-group-addon">C. Address</span> <input style="width:390px" ng-model="currentItem.CustomerAddress" class="form-control" type="text"> </div> </div> Modal <div ng-controller="JobCtrl" data-backdrop="static" data-keyboard="false" class="modal fade" id="editJobCustomerModal" tabindex="-1" role="dialog" aria-labelledby="edit" aria-hidden="true"> <div class=" modal-dialog modal-editJobCustomer"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title custom_align" id="Heading">Change Job Customer</h4> </div> <div class="modal-body"> <div class="container"> <form ng-submit="submitJob()" enctype="multipart/form-data"> <fieldset> <div class="col-md-8"> <!-- Prepended text--> <div class="form-group"> <div class="input-group"> <span class="input-group-addon">C.

  • Populating array of input fields as alternate fields using jQuery UI datepicker

    - by Micor
    I am using jquery ui datepicker in order to populate start and end dates for multiple events on the same page, the number of events is dynamic and I need to post day, month and year as separate fields, so I have something like this: <input type="text" name="event[0].startDate" class="date"/> <input type="hidden" name="event[0].startDate_day" class="startDate_day" /> <input type="hidden" name="event[0].startDate_month" class="startDate_month" /> <input type="hidden" name="event[0].startDate_year" class="startDate_year" /> <input type="text" name="event[0].endDate" class="date"/> <input type="hidden" name="event[0].endDate_day" class="endDate_day" /> <input type="hidden" name="event[0].endDate_month" class="endDate_month" /> <input type="hidden" name="event[0].endDate_year" class="startDate_year" /> event[1]... event[2]... I started working on jQuery functionality and this is what I have so far, which will populate alternate fields for startDate by class, of course it will not do what I need because I need to populate by field name rather then class: $(".date").datepicker({ onClose: function(dateText,picker) { $('.startDate_month').val( dateText.split(/\//)[0] ); $('.startDate_day').val( dateText.split(/\//)[1] ); $('.startDate_year').val( dateText.split(/\//)[2] ); }}); I need help figuring out how can I get the name of the input field within datepicker function so the alternate field assignment done by that field name + _day, month, year so this function can work for all the events on the page, making function above look more like: $(".date").datepicker({ onClose: function(dateText,picker) { $('input[' + $name + '_month' + ']').val( dateText.split(/\//)[0] ); $('input[' + $name + '_day' + ']').val( dateText.split(/\//)[1] ); $('input[' + $name + '_year' + ']').val( dateText.split(/\//)[2] ); }}); Hope that makes sense :) Thanks

  • How to Deserialize Missing Fields To Nulls

    - by Nathan
    I am working on a .NET project where several versions of the same type of object have been created over the life of the project - most new versions add a field or two. However, now I am looking to mitigate problems for users with an old version. My goal is that when a user tries to open an old version of the serialized object with the new program, the program will automatically assign default values to the fields that are missing from the depreciated version of the file. For example, say I had a class with two boolean fields - RepeatSound and RepeatForever. The first version of the program doesn't know how to repeat forever, so it only saved RepeatSound: <anyType xsi:type="Sound"> <RepeatSound>true</RepeatSound> </anyType> but the new files look like this: <anyType xsi:type="Sound"> <RepeatSound>true</RepeatSound> <RepeatForever>true</RepeatForever> </anyType> My goal is that when I deserialize the first file in the new program that it will create the Sound object but simply default the value of RepeatForever to false. Right now trying to deserialize the first object would throw an exception. Thank you in advance for any responses
