  • Accessing Python module fails although its package is imported

    - by codethief
    Hey Stackers! :) My Django project's directory hierarchy looks like this: + pybsd |---+ devices |---+ templates |---+ views |---+ interaction |---- __init__.py |---- geraete.py |---- geraetemodelle.py |---- geraetegruppen.py |---- __init__.py |---- ajax.py |---- html.py |---- misc.py |---- __init__.py |---- urls.py |---- __init__.py |---- urls.py (Please excuse the German names. I preferred not to replace them here since it would add yet another possible error source when trying out the solutions you'll hopefully suggest and answering your questions.) Every request to http://URL/devices/.* is dispatched to the urls.py file living in /devices: # ... from views import html, ajax, misc, interaction urlpatterns = patterns('', # ... (r'^ajax/update/(?P<table>[a-z_]+)$', ajax.update), (r'^ajax/delete/(?P<table>[a-z_]+)$', ajax.delete), (r'^ajax/select_options/(?P<table>[a-z_]+)$', ajax.select_options), (r'^interaction/geraete/info/(?P<geraet>\d+)$', interaction.geraete.info), (r'^interaction/geraete/delete/(?P<geraet>\d+)?$', interaction.geraete.delete), (r'^interaction/geraetemodelle/delete/(?P<geraetemodell>\d+)?$', interaction.geraetemodelle.delete), (r'^interaction/geraetegruppen/delete/(?P<geraetegruppe>\d+)?$', interaction.geraetegruppen.delete), # ... ) All URL definitions work except for those referencing the interaction package. I'm constantly getting the following error: File "/home/simon/projekte/pybsd/../pybsd/devices/urls.py", line 33, in `<module>` (r'^interaction/geraete/info/(?P<geraet>\d+)$', interaction.geraete.info), AttributeError: 'module' object has no attribute 'geraete' I double-checked that the __init__.py files don't contain anything. Maybe you've already found the (Python- or Django-related?) mistake I made and am apparently unable to see. If not, read on. In any case, thanks for reading this long post! Isolating the problem 1st test It works if I provide the view functions as strings: (r'^interaction/geraete/info/(?P<geraet>\d+)$', 'devices.views.interaction.geraete.info'), (r'^interaction/geraete/delete/(?P<geraet>\d+)?$', 'devices.views.interaction.geraete.delete'), (r'^interaction/geraetemodelle/delete/(?P<geraetemodell>\d+)?$', 'devices.views.interaction.geraetemodelle.delete'), (r'^interaction/geraetegruppen/delete/(?P<geraetegruppe>\d+)?$', 'devices.views.interaction.geraetegruppen.delete'), ... or add yet another line to the imports: from views.interaction import geraete, geraetemodelle, geraetegruppen Using from views.interaction import *, however, doesn't work either and results in the same error message. 2nd test I created a file test.py in /devices: from views import interaction print dir(interaction) Output: simon@bsd-simon:~/projekte/pybsd/devices$ python test.py ['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__'] Again, no sign of the modules I created in the interaction package (geraete.py, geraetemodelle.py, geraetegruppen.py). Unlike in urls.py, trying from view.interaction import geraete, geraetegruppen, geraetemodelle in test.py results in ImportError: No module named view.interaction this time. 3rd test I started the Django shell: $ python manage.py shell >>> import devices.views.interaction.geraete >>> dir(devices.views.interaction.geraete) ['Abteilung', 'Auftrag', 'Auftragsvorlage', 'Geraet', 'Geraetegruppe', 'Geraetemodell', 'HttpResponse', 'HttpResponseBadRequest', 'HttpResponseRedirect', 'Raum', 'Standort', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'delete', 'info', 'models', 'move', 'render_to_response'] >>> $ python manage.py shell >>> from devices.views.interaction import geraete >>> dir(geraete) ['Abteilung', 'Auftrag', 'Auftragsvorlage', 'Geraet', 'Geraetegruppe', 'Geraetemodell', 'HttpResponse', 'HttpResponseBadRequest', 'HttpResponseRedirect', 'Raum', 'Standort', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'delete', 'info', 'models', 'move', 'render_to_response'] >>> $ python manage.py shell >>> import devices.views.interaction >>> devices.views.interaction.geraete Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: 'module' object has no attribute 'geraete' >>> dir(devices.views.interaction) ['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']

  • RSS Feeds currently on Simple-Talk

    - by Andrew Clarke
    There are a number of news-feeds for the Simple-Talk site, but for some reason they are well hidden. Whilst we set about reorganizing them, I thought it would be a good idea to list some of the more important ones. The most important one for almost all purposes is the Homepage RSS feed which represents the blogs and articles that are placed on the homepage. Main Site Feed representing the Homepage ..which is good for most purposes but won't always have all the blogs, or maybe it will occasionally miss an article. If you aren't interested in all the content, you can just use the RSS feeds that are more relevant to your interests. (We'll be increasing these categories soon) The newsfeed for SQL articles The .NET section newsfeed The newsfeed for Red Gate books The newsfeed for Opinion articles The SysAdmin section newsfeed if you want to get a more refined feed, then you can pick and choose from these feeds for each category so as to make up your custom news-feed in the SQL section, SQL Training Learn SQL Server Database Administration TSQL Programming SQL Server Performance Backup and Recovery SQL Tools SSIS SSRS (Reporting Services) in .NET there are...

  • Provisioning Videos

    - by Owen Allen
    There are a couple of new videos up on the Oracle Learning Youtube channel about Ops Center's provisioning capabilities. Simon Hayler does a walkthrough of a couple of different procedures. The first video shows you how to provision Oracle Solaris zones. It explains how to create an Oracle Solaris Zone profile, and then how to apply it (using a deployment plan) to a target system. The second video shows you how to provision an x86 server with Oracle Solaris. This uses a very similar process - you create a OS provisioning profile, then use a deployment plan to apply it to the target hardware. The documentation goes over OS provisioning and zone creation in the Feature Guide, if you're looking for additional information.

  • Open World Day 3

    - by Antony Reynolds
    A Day in the Life of an Oracle OpenWorld Attendee Part IV My third day was exhibition day for me!  I took the opportunity to wander around the JavaOne and OpenWorld exhibitions to see what might be useful for me when selling WebLogic, Coherence & SOA Suite.  I found a number of interesting vendors and thought I would share what I found here.  These are not necessarily endorsements, but observations on companies that I thought had interesting looking products that fill a need I have seen at customers. Highly Available EBS Upgrades A few years ago I worked with a customer that was a port authority.  They wanted to tie E-Business Suite into their operations to provide faster processing of cargo and passengers.  However they only had a 2 hour downtime window to perform upgrades.  This was not a problem for core database and middleware technology, this could accommodate those upgrade timescales easily.  It was a problem for EBS however so I intrigued to find Rapid E-Suite Inc offering an 11i to 12i upgrade service that claims to require no outage.  This could be a real boon to EBS customers like my port friends that need to upgrade without disruption to their business. Mobile on WebLogic I have come across a number of customers who want a comprehensive mobile solution, connected and disconnected operation and so forth.  ADF only addresses part of these requirements currently so I was excited to discover mFrontiers Inc offering an apparently comprehensive solution that should integrate easily with Oracle SOA Suite to mobile enable a SOA infrastructure.  The ability to operate without a network is important for many applications, particularly in industries that require their engineers to enter buildings to perform maintenance or repairs, because network access is not always available – many of my colleagues don’t have mobile access from their homes because they live in the middle of nowhere – and disconnected support is crucial in these situations. Sharepoint Connector for WebCenter Content Obviously Sharepoint is an evil pernicious intrusion into a companies IT estate but it is widely deployed and many people like it but also would like to take advantage of Oracle products such as WebCenter Content.  So I was encouraged to see that Fishbowl Solutions have created a connector for Sharepoint that allows it to bring in content from WebCenter, it looks like a valuable way to maintain the Sharepoint interface end users are used to but extend the range of content by pulling stuff (technical term for content) from WebCenter.   Load Balancing The Enterprise Deployment Guides are Oracles bible on building highly available FMW environments, and each of them requires a front end load balancer.  I have been asked to help configure F5 Load Balancers on a number of occasions over my time at Oracle and each time I come back to it I find more useful features have been added to the BigIP line of load balancers that F5 sell, many of their documents are tailored to FMW.  I like F5, they provide (relatively) easy to use products that do what they say on the side of the box.  They may not have all the bells and whistles of some of their more expensive competitors but they do the job and do it well!  Besides which I like their logo! Other Stuff I saw lots of other interesting products and services, such as a lightweight monitoring tool for Coherence, Forms migration services, JCAPS migration services and lots of cool freebies to take home to the children! A Quiet Night Wednesday night was the partner appreciation event and I had decided to go back to the hotel and have an early night.  I decided to attend the last session of the day – a Maven/Hudson/WebLogic tutorial.  I got the wrong hotel for the session and snuck in 20 minutes late at the back and starting working on the hands on workshop.  One of my co-attendees raised his hand for help and as the presenter came over to help he suddenly stopped and yelled – “Is that Antony”!  It was my old friend Steve Button who used to be based in Redwood Shores but is now a WebLogic guru PM in Australia.  It was good to catch up with him.  As he yelled out a guy with really bad posture turned around to see who he was talking to, this turned out to be my friend Simon Haslan, Oracle ACE from the UK.  After the tutorial Simon and I retired to the coffee shop to catch up and share stories.  2 and half hours later we decided it was time to retire, so much for an early night but great to renew old friendships and find out what real customers are worrying about.

  • Session Report - Java on the Raspberry Pi

    - by Janice J. Heiss
    On mid-day Wednesday, the always colorful Oracle Evangelist Simon Ritter demonstrated Java on the Raspberry Pi at his session, “Do You Like Coffee with Your Dessert?”. The Raspberry Pi consists of a credit card-sized single-board computer developed in the UK with the intention of stimulating the teaching of basic computer science in schools. “I don't think there is a single feature that makes the Raspberry Pi significant,” observed Ritter, “but a combination of things really makes it stand out. First, it's $35 for what is effectively a completely usable computer. You do have to add a power supply, SD card for storage and maybe a screen, keyboard and mouse, but this is still way cheaper than a typical PC. The choice of an ARM (Advanced RISC Machine and Acorn RISC Machine) processor is noteworthy, because it avoids problems like cooling (no heat sink or fan) and can use a USB power brick. When you add in the enormous community support, it offers a great platform for teaching everyone about computing.”Some 200 enthusiastic attendees were present at the session which had the feel of Simon Ritter sharing a fun toy with friends. The main point of the session was to show what Oracle was doing to support Java on the Raspberry Pi in a way that is entertaining and fun. Ritter pointed out that, in addition to being great for teaching, it’s an excellent introduction to the ARM architecture, and runs well with Java and will get better once it has official hard float support. The possibilities are vast.Ritter explained that the Raspberry Pi Project started in 2006 with the goal of devising a computer to inspire children; it drew inspiration from the BBC Micro literacy project of 1981 that produced a series of microcomputers created by the Acorn Computer company. It was officially launched on February 29, 2012, with a first production of 10,000 boards. There were 100,000 pre-orders in one day; currently about 4,000 boards are produced a day. Ritter described the specification as follows:* CPU: ARM 11 core running at 700MHz Broadcom SoC package Can now be overclocked to 1GHz (without breaking the warranty!) * Memory: 256Mb* I/O: HDMI and composite video 2 x USB ports (Model B only) Ethernet (Model B only) Header pins for GPIO, UART, SPI and I2C He took attendees through a brief history of ARM Architecture:* Acorn BBC Micro (6502 based) Not powerful enough for Acorn’s plans for a business computer * Berkeley RISC Project UNIX kernel only used 30% of instruction set of Motorola 68000 More registers, less instructions (Register windows) One chip architecture to come from this was… SPARC * Acorn RISC Machine (ARM) 32-bit data, 26-bit address space, 27 registers First machine was Acorn Archimedes * Spin off from Acorn, Advanced RISC MachinesNext he presented its features:* 32-bit RISC Architecture–  ARM accounts for 75% of embedded 32-bit CPUs today– 6.1 Billion chips sold last year (zero manufactured by ARM)* Abstract architecture and microprocessor core designs– Raspberry Pi is ARM11 using ARMv6 instruction set* Low power consumption– Good for mobile devices– Raspberry Pi can be powered from 700mA 5V only PSU– Raspberry Pi does not require heatsink or fanHe described the current ARM Technology:* ARMv6– ARM 11, ARM Cortex-M* ARMv7– ARM Cortex-A, ARM Cortex-M, ARM Cortex-R* ARMv8 (Announced)– Will support 64-bit data and addressingHe next gave the Java Specifics for ARM: Floating point operations* Despite being an ARMv6 processor it does include an FPU– FPU only became standard as of ARMv7* FPU (Hard Float, or HF) is much faster than a software library* Linux distros and Oracle JVM for ARM assume no HF on ARMv6– Need special build of both– Raspbian distro build now available– Oracle JVM is in the works, release date TBDNot So RISCPerformance Improvements* DSP Enhancements* Jazelle* Thumb / Thumb2 / ThumbEE* Floating Point (VFP)* NEON* Security Enhancements (TrustZone)He spent a few minutes going over the challenges of using Java on the Raspberry Pi and covered:* Sound* Vision * Serial (TTL UART)* USB* GPIOTo implement sound with Java he pointed out:* Sound drivers are now included in new distros* Java Sound API– Remember to add audio to user’s groups– Some bits work, others not so much* Playing (the right format) WAV file works* Using MIDI hangs trying to open a synthesizer* FreeTTS text-to-speech– Should work once sound works properlyHe turned to JavaFX on the Raspberry Pi:* Currently internal builds only– Will be released as technology preview soon* Work involves optimal implementation of Prism graphics engine– X11?* Once the JavaFX implementation is completed there will be little of concern to developers-- It’s just Java (WORA). He explained the basis of the Serial Port:* UART provides TTL level signals (3.3V)* RS-232 uses 12V signals* Use MAX3232 chip to convert* Use this for access to serial consoleHe summarized his key points. The Raspberry Pi is a very cool (and cheap) computer that is great for teaching, a great introduction to ARM that works very well with Java and will work better in the future. The opportunities are limitless. For further info, check out, Raspberry Pi User Guide by Eben Upton and Gareth Halfacree. From there, Ritter tried out several fun demos, some of which worked better than others, but all of which were greeted with considerable enthusiasm and support and good humor (even when he ran into some glitches).  All in all, this was a fun and lively session.

  • Get Name by Cellphone number

    - by ganti
    Hy everyone I'm using a TextField where the user is typing in a phonenumber. When the TextField has changed it should check if this number is allready in the phonebook and display the name. So far, my only way is to parse all names and number in a Dict and read it from there. Is there a simpler more efficient and sophisticated way to do that. cheers simon

  • Setting an individual DataGridView Cell

    - by user315493
    Hi, In a DataGridView, it is possible to set an individual DataGridViewCell like this: dataGridView.Item(columnIndex, rowIndex) = New DataGridViewTextBoxCell. However, is the new DataGridViewCell is set before his owning column become visible, it seems that the individual cell will be replaced (or marked?) by the column default cell. Is there a way to fix this? Regards, Simon
