  • smartif tag not working out correctly

    - by 47
    I'm using the smartif tag from this snippet (I'm holding on with regards to upgrading to 1.2) in my template for a certain boolean field like so: {% if payment.extends_membership == "True" %} {% trans "Yes" %} {% else %} {% trans "No" %} {% endif %} But whatever the value of extends_membership I get only No as the output. What could be the problem?

  • Some tables mixed together

    - by DJPython
    Hello. I have 2 different tables in my database. They have some variables common and some different. For example: Table1: ID Date Name Address Fax Table2: ID Date Name e-mail Telephone number I want to display data together sorted by date & ID but from both tables. For example, first displayed will be the newest record from first table, but the second one will be the record from another table posted right after first one. Hope everybody understand, sorry for my English. Cheers.

  • Setting a form field's valule during validation

    - by LaundroMat
    Hi, I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method). Thanks in advance!

  • Adding nodes to MAAS server

    - by Yasith Tharindu
    I was able to install MAAS server using ubuntu 12.04. Then boot up nodes from he PXE. Then installed maas-precise-x86-64-commissioning through pxe. Now the installation is done. but im unable to commission with the MAAS server. It does not show it as a node and neither im unable to add it manually and end up with following error. Also what is the default username password for maas-precise-x86-64-commissioning. Im unable to login. This error when adding node manually.

  • Android: How to receive process signals in an activity to kill child process ?

    - by user355993
    My application calls Runtime.exec() to launch an executable in a separate process at start up time. I would like this child process to get killed when the parent activity exits. Now I can use onDestroy() to handle regular cases, but not "Force quit", shutdowns from DDMS, or kill from the console since those don't run onDestroy(). The addShutdownHandler() does not seem to be invoked in these cases either. Is there any other hook or signal handler that informs my activity that it's about to get terminated ? As an alternative is there a way to have the system automatically kill the child process when the parent dies ?

  • How to add event listners / signals to a simple superman class?

    - by Kabumbus
    I can and would love to use boost or std for this. Sorry - I am new to C++. So I created a really simple program like: #include <iostream> #include <string> using namespace std; class superman { public: string punch(){return cout << "superman: I hit the bad guy!" << endl;}; }; int main() { superman clark; clark.punch(); cin.get(); } I want to add an event listner that would tell me when clark punched and cout something like "superman punched!". How to add such event listner and event function to my class?

  • Computer Networks UNISA - Chap 8 &ndash; Wireless Networking

    - by MarkPearl
    After reading this section you should be able to Explain how nodes exchange wireless signals Identify potential obstacles to successful transmission and their repercussions, such as interference and reflection Understand WLAN architecture Specify the characteristics of popular WLAN transmission methods including 802.11 a/b/g/n Install and configure wireless access points and their clients Describe wireless MAN and WAN technologies, including 802.16 and satellite communications The Wireless Spectrum All wireless signals are carried through the air by electromagnetic waves. The wireless spectrum is a continuum of the electromagnetic waves used for data and voice communication. The wireless spectrum falls between 9KHZ and 300 GHZ. Characteristics of Wireless Transmission Antennas Each type of wireless service requires an antenna specifically designed for that service. The service’s specification determine the antenna’s power output, frequency, and radiation pattern. A directional antenna issues wireless signals along a single direction. An omnidirectional antenna issues and receives wireless signals with equal strength and clarity in all directions The geographical area that an antenna or wireless system can reach is known as its range Signal Propagation LOS (line of sight) uses the least amount of energy and results in the reception of the clearest possible signal. When there is an obstacle in the way, the signal may… pass through the object or be obsrobed by the object or may be subject to reflection, diffraction or scattering. Reflection – waves encounter an object and bounces off it. Diffraction – signal splits into secondary waves when it encounters an obstruction Scattering – is the diffusion or the reflection in multiple different directions of a signal Signal Degradation Fading occurs as a signal hits various objects. Because of fading, the strength of the signal that reaches the receiver is lower than the transmitted signal strength. The further a signal moves from its source, the weaker it gets (this is called attenuation) Signals are also affected by noise – the electromagnetic interference) Interference can distort and weaken a wireless signal in the same way that noise distorts and weakens a wired signal. Frequency Ranges Older wireless devices used the 2.4 GHZ band to send and receive signals. This had 11 communication channels that are unlicensed. Newer wireless devices can also use the 5 GHZ band which has 24 unlicensed bands Narrowband, Broadband, and Spread Spectrum Signals Narrowband – a transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies Broadband – uses a relatively wide band of the wireless spectrum and offers higher throughputs than narrowband technologies The use of multiple frequencies to transmit a signal is known as spread-spectrum technology. In other words a signal never stays continuously within one frequency range during its transmission. One specific implementation of spread spectrum is FHSS (frequency hoping spread spectrum). Another type is known as DSS (direct sequence spread spectrum) Fixed vs. Mobile Each type of wireless communication falls into one of two categories Fixed – the location of the transmitted and receiver do not move (results in energy saved because weaker signal strength is possible with directional antennas) Mobile – the location can change WLAN (Wireless LAN) Architecture There are two main types of arrangements Adhoc – data is sent directly between devices – good for small local devices Infrastructure mode – a wireless access point is placed centrally, that all devices connect with 802.11 WLANs The most popular wireless standards used on contemporary LANs are those developed by IEEE’s 802.11 committee. Over the years several distinct standards related to wireless networking have been released. Four of the best known standards are also referred to as Wi-Fi. They are…. 802.11b 802.11a 802.11g 802.11n These four standards share many characteristics. i.e. All 4 use half duplex signalling Follow the same access method Access Method 802.11 standards specify the use of CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to access a shared medium. Using CSMA/CA before a station begins to send data on an 802.11 network, it checks for existing wireless transmissions. If the source node detects no transmission activity on the network, it waits a brief period of time and then sends its transmission. If the source does detect activity, it waits a brief period of time before checking again. The destination node receives the transmission and, after verifying its accuracy, issues an acknowledgement (ACT) packet to the source. If the source receives the ACK it assumes the transmission was successful, – if it does not receive an ACK it assumes the transmission failed and sends it again. Association Two types of scanning… Active – station transmits a special frame, known as a prove, on all available channels within its frequency range. When an access point finds the probe frame, it issues a probe response. Passive – wireless station listens on all channels within its frequency range for a special signal, known as a beacon frame, issued from an access point – the beacon frame contains information necessary to connect to the point. Re-association occurs when a mobile user moves out of one access point’s range and into the range of another. Frames Read page 378 – 381 about frames and specific 802.11 protocols Bluetooth Networks Sony Ericson originally invented the Bluetooth technology in the early 1990s. In 1998 other manufacturers joined Ericsson in the Special Interest Group (SIG) whose aim was to refine and standardize the technology. Bluetooth was designed to be used on small networks composed of personal communications devices. It has become popular wireless technology for communicating among cellular telephones, phone headsets, etc. Wireless WANs and Internet Access Refer to pages 396 – 402 of the textbook for details.

  • virtualenv on Windows: not over-riding installed package

    - by Tom
    My current setup is Python 2.5/ Django 1.1.1 on Windows. I want to start using Django 1.2 on some projects, but can't use it for everything. Which is just the sort of thing I've got virtualenv for. However, I'm running into a problem I've never encountered and it's hard to Google for: installing Django 1.2 into a virtualenv has no effect for me. If I then activate the environment and do python import django django.VERSION I get "1.1.1 Final". Django is installed in the site-packages directory of my environment and the init file in the root shows that it is 1.2. But the environment falls back to 1.1.1, even if I create the environment with the --no-site-packages flag. What am I screwing up?

  • Play or Lift: which one is more explicit?

    - by Andrea
    I am going to investigate web development with Scala, and the choice is between learning Lift or Play: probably I will not have enough time to try both, at least at first. Now, many comparisons between the two are available on the internet, but I would like to know how do they compare with respect to being explicit and involving less magic. Let me explain what I mean by example. I have used, to various degrees, CakePHP, symfony2, Django and Grails. I feel a very clear distinction between Django and symfony2, which are very explicit about what you are doing, and Grails and CakePHP, which try to do their best to guess what you are trying to achieve and often feel "magical". Let me give some examples comparing Django and Grails. In Django, views are functions that take a request as input and return a response. You can instantiate explicitly an instance of HttpResponse and populate its body with a string, or you can use shortcut functions to leverage the template system. In any case the return value from your view always has the same type. In contrast, the render method from Grails is highly polymorphic. You can throw a context at it and it will try to render a template which is found by convention using that context. Or you can pass it a pair of a template path and a context and that will work too. Or a string. Or XML. Grails tries hard to make sense of whatever you return from your controller. In the Django ORM, each model class has a static attribute representing the manager for that class. That manager exposes a fluent interface to build querysets. In Grails, you can have a similar functionality by composing detached criteria. Still, the most common way to query objects seems to be the use of runtime-generated methods like FindUserByEmailNotNull or FindPostByDateGreaterThan. I will not go further, but my point is that in Django-like frameworks you have control over the whole flow of the request/response process, while in Grails-like ones I feel I only have to feel the blanks and the framework will manage the rest of the flow for me. This is not to criticize Grails or CakePHP; which type you prefer is mainly a matter of preference. In fact, I happen to like some aspects of Grails, but I feel more comfortable with a framework which does less for me. Back to the point of the question: which one among Play and Lift is more explicit about what you do and which one tries to simplify more what you have to do with a layer of "magic"?

  • Komodo Edit - How to disable the 'Linter' for a language?

    - by TM.
    I've been using Komodo Edit to work on a Django project. It works great except for one little annoyance: When I am editing Django template files, Komodo likes to put red squiggly lines underneath the first HTML tag that follows a Django tag, because it thinks it is an invalid HTML doc (although it isn't, it just has Django template tags/filters in it). Note that this red squiggly line is called a "Linter error" in the docs that I can find. Is there some way to turn off this red squiggly for only a specific type of language? It's nice to have when working on Python code but it's annoying to have a red squiggly on every single one of my Django templates.

  • Python virtualenv questions

    - by orokusaki
    I'm using VirtualEnv on Windows XP. I'm wondering if I have my brain wrapped around it correctly. I ran virtualenv ENV and it created C:\WINDOWS\system32\ENV. I then changed my PATH variable to include C:\WINDOWS\system32\ENV\Scripts instead of C:\Python27\Scripts. Then, I checked out Django into C:\WINDOWS\system32\ENV\Lib\site-packages\django-trunk, updated my PYTHON_PATH variable to point the new Django directory, and continued to easy_install other things (which of course go into my new C:\WINDOWS\system32\ENV\Lib\site-packages directory). I understand why I should use VirtualEnv so I can run multiple versions of Django, and other libraries on the same machine, but does this mean that to switch between environments I have to basically change my PATH and PYTHON_PATH variable? So, I go from developing one Django project which uses Django 1.2 in an environment called ENV and then change my PATH and such so that I can use an environment called ENV2 which has the dev version of Django? Is that basically it, or is there some better way to automatically do all this (I could update my path in Python code, but that would require me to write machine-specific code in my application)? Also, how does this process compare to using VirtualEnv on Linux (I'm quite the beginner at Linux).

  • How to implement Template Inheritance (like Django?) in PHP5

    - by anonymous coward
    Is there an existing good example, or how should one approach creating a basic Template system (thinking MVC) that supports "Template Inheritance" in PHP5? For an example of what I define as Template Inheritance, refer to the Django (a Python framework for web development) Templates documentation: http://docs.djangoproject.com/en/dev/topics/templates/#id1 I especially like the idea of PHP itself being the "template language", though it's not necessarily a requirement. If listing existing solutions that implement "Template Inheritance", please try to form answers as individual systems, for the benefit of 'popular vote'.

  • Grails benchmarks compared to other web MVC platform (Rails, Django, ASP MVC)?

    - by fabien7474
    I have been searching the web for recent benchmarks measuring Grails overall performance compared to its competitors (Rails, Django, ASP.NET MVC...), but I didn't find anything more recent than a 3 years-old article with obsolete grails version (0.5). See here and here. So, starting from grails 1.2, are there any more recent grails benchmarks you are aware of ? Or do you have your own performance tests for grails (compared to others if possible) ?

  • Recommend good shared hosting [closed]

    - by Django Reinhardt
    It seems that everyone has something bad to say about the "big" shared hosting sites like 1and1, HostGator, GoDaddy, etc. but what are the ones you've had GOOD experiences with? I'm going to focus this question on LAMP stacks, given that they're the most popular option for shared hosting, but if you have an especially good experience with a different stack. Good shared hosting should be: Competitively priced - But not at the expense of... Fully featured - Email, PHP, MySQL, but what else? Highly customizable - Do you have access to advanced features like being able to deliver static content? Up to date - Do they run PHP4 as standard, or do they run the latest version? Customer service - When you have a problem are they rude and unhelpful? Do they take ages to reply? So how about it? Who have YOU have a good experience with?

  • 1and1: Unable to host an external domain

    - by Django Reinhardt
    I'm sorry if this isn't the right place for this question, but I'm presently having difficulties with my hosting provider (1and1). Two weeks ago, two of my clients bought hosting from them on my recommendation, but as it turned out, 1and1 are having severe technical difficulties. Right now non of their hosting packages are able to accept ANY external domains. So either you pay the costs of transferring the registrar of your domain, or you use the ugly 1and1 domain name. Not any good for a hosting company of 1and1's reputation! They have been promising me for two weeks that they're going to fix the problem, but as you have probably guessed by now, that hasn't been the case. I would like to know if a) Anyone else is in the same boat as me, and b) If there are other comparably reputable hosting providers that I should consider moving to instead? Very disappointing! :( Note: This is for 1and1 in the UK. I imagine it isn't affecting users in other countries(?) Clarification: 1and1 are unable to accept ANY external domains. That means that even if you update your DNS details on your domain, their system cannot be updated to add your external domain to your account.
