Let's say I have a Django project myproj, with an app myapp. In myproj/myapp, there is a file called const.py, which is included in the app's views file, and loads some constants from a text file. This text file is located at myproj/myapp/myfile.txt.
In const.py, the following code works fine when the web server is operating:
with open('myapp/myfile.txt')
But if I move to the directory myproj/myapp and from the command line run python const.py, I get an error saying that it cannot find the file myapp/myfile.txt. In order to make it work from the command line, I have to change const.py to:
with open('myfile.txt')
However, this then does not work for the web server. I understand why the first version doesn't work from the command line. But what I don't understand is why the first version works when the web server is running, whilst the second version doesn't. If const.py is in the same directory as myfile.txt, then surely the web server will search that same directory for myfile.txt. Why is it not finding it then? And why, when it searches for myapp/myfile.txt can it find a file, which is in the same directory as const.py?
Thanks!

I have created some Java applications to extend Rhapsody using Java API and I have deployed them successfully to the Rhapsody environment (Right click on the project -> Apps).
I can see the exported .jar files under the directory RhapsodyApps/apps.
My question is, How can I run them from the command line (Under windows 7)???
Thank you in advance
What I managed to do is to create a .bat file, using "Generate Apps Execution Batch File". As I mentioned in my last post it did not exist in the "Apps" menu of rhapsody. Besides, it existed in the "...\share\RhapsodyApps\apps" directory with the name "SynchronousScriptInvocation.jar". I hardcoded the RhapsodyApps.hep file, by adding the following:
#REM: This app generates a script which will invoke each app synchronously one after another. ...
name7=Apps\Generate Apps Execution Batch File
isPluginCommand7=1
command7=Apps
applicableTo7=Project,SysML,AUTOSAR_40,AUTOSAR_31,AUTOSAR_32,DDS,UPDM1_DoDAF20,UPDM2_DoDAF
isVisible7=1
I got the name (Generate Apps Execution Batch File) from the AppInfos.xml file.
Then, the plugin is displayed in the Apps menu in Rhapsody IDE, and I can generate the .bat file. Problems did not stop here. The batch file was not displaying my plugin and the reason was something with my JAVA_PATH configuration. Finally I modified the .bat file as following:
#rem This is auto generated script. Be careful on changing it manually.
#rem Build Order
set APP0=0df8829923eb43f4aab9d33ada1ddbf1
#set APPS= %APP0%
set JAVA_PATH=%JAVA_PATH%\bin\java
set JAVA_API=C:/work/User/Build.TRUNK/ProjectName/RhapsodyShare8/JavaAPI
set RhapsodyApps=C:/work/User/Build.TRUNK/ProjectName/RhapsodyShare8/RhapsodyApps
set CLASS_PATH="%RhapsodyApps%"/apps/RhapsodyAppLauncher.jar;"%RhapsodyApps%"/RhapsodyApps.jar;"%RhapsodyApps%"/apps.jar;"%JAVA_API%"/rhapsody.jar
"C:\Program Files (x86)\IBM\Rational\Rhapsody\8.0.5\jre\bin\java" -cp %CLASS_PATH% -Djava.library.path="%JAVA_API%" apps.RhapsodyLauncherApp %APPS%
Finally it works. I hope that this post will help somebody in the future.
I have deployed my webapplication on a jetty server, and I am trying to edit those deployed files using WebStorm 8.0.4. But I am unable to save the edited files and getting the following error:
Try turning the 'safe write' feature (Settings/General, 'Use safe writes') off - does it help? It creates a temporary copy of a file: creates a separate temp file, deletes the original and then renames. With this option the original file permissions may be lost, this causes problems, especially when working on remote drives.
Follow these steps.
Open C:\Users\YourUserName\.m2\repository (If you use maven)
Find org folder and Navigate org\eclipse\jetty\jetty-webapp\yourJettyVersion
There will be a .jar file.
Open it with winrar or some program like winrar.
Navigate org\eclipse\jetty\webapp
Find webdefault.xml and Open it with any text editor.
Search useFileMappedBuffer parameter in file
You will see a param value.
Change it to false.
Save and Exit.
I'm sorry for any English mistakes.
I am beginning a project on Python that implements PyAIML and I wrote the following code to create a brain for my project:
import aiml
k=aiml.Kernel()
k.learn("std-startup.xml")
k.respond("LOAD AIML B")
k.saveBrain("jarvis.brn")
When I run the program I get this error: WARNING: No match found for input: LOAD AIML B
I understand that I needed to download an AIML set to begin development. So I did, but I'm stuck there.
Please help. I'm a noob programmer so don't be rough on me for this dumb mistake.
Thanks in advance!
The .learn() method will not throw an error if the file you pass it does not exist, and I'm guessing that you are trying to learn patterns from "std-startup.xml" without having this file in your directory.
Make sure the file std-startup.xml is in the directory you are running your script from. You should also have a directory called standard in your working directory that contains the standard set of aiml files. Basically your directory should look like this:
mydir/my_script.py
mydir/std-startup.xml
mydir/standard/a-bunch-of-std-aiml-files.aiml
These files can be found in the "Other Files/Standard AIML Set/" folder on the pyaiml source forge site. Go to that folder and download the one of the tarballs or the zip.
A few things:
If your AIML is loading properly, pyAIML will respond with a line that will read something like:
Loading std-startup.aiml... done (1.00 seconds)
It will not necessarily throw an error if it does not find a file to load, so if you don't see this line, pyAIML has not loaded the AIML file.
I don't see 'std-startup.xml' in the sourceforge directory either, but this shouldn't matter. All that you're loading is any AIML file that will allow you to test the kernel. Try loading the 'self-test.aiml' file in the /aiml directory instead. (Double-check to make sure the file suffix in your code is .aiml and not .xml)
k.respond() is for giving the bot some input and 'LOAD AIML B' is just a test phrase. Once you've loaded 'self-test.aiml' try k.respond('test date') and you should get
The date is Wed Mar 13 01:37:07 2013 in response.
I recently wrote a few scripts for Javascript which I am trying to run as a native app on my iPad in offline mode.
The scripts do nothing complex, simply run off a bunch of prompts and generate a document.write() based on the information the user has entered.
So I set up my own little website to host the scripts on and went about setting up an application cache. I am new to this sort of thing however from what I gather, I have followed instructions correctly. To set up my app cache, I did the following:
Added the following two lines to my .htaccess file:
AddType text/cache-manifest .manifest
AddType text/manifest .manifest
Made a new file called "generator.manifest", which has the following lines:
CACHE MANIFEST
generator.html
answergenerator.js
And added in to my generator.html file:
Apart from a few functions used to prompt some iOS features, all I have in my generator.html file is this:
along with the other stock standard html tags.
That is my appcache setup. The generator.manifest file is in the exact same directory as the generator.html file.
When I enter Firefox and go to my site, I can run the script, allow it to cache files for offline usage (Firefox comes up with a prompt), and then run the script in offline mode.
HOWEVER, whenever I try to do this on my iPad (4.2.1), I simply get the error: "Generator could not be opened because it is not connected to the Internet."
Where have I gone wrong? Can someone help me fix this please?
A huge thanks in advance,
Haz.
You might look at this answer. iOS does seem to have some issues. I found that I had to power cycle my iPad (in addition to clearing open Safari's) before it would recognize the appcache.
I have written a Django project which runs fine on the dev server. Although I am the only one working on it, I realized I should get some sort of version control going and placed the project on a network SVN. I assume the new process for working this project should be: checkout code from SVN, make changes, test, update, and commit back to SVN.
However, when I check out the code and attempt to run the dev server from the checked out SVN location, I get an error that "has no module named yadda.yadda". But, the module is there and it works fine when I run it from the original directory. Any thoughts? Any suggestions on a better work process?
Does your $PYTHONPATH shell variable reference a relative path? If so, the relative path may be incorrect when you change to the new directory.
You can also diff the contents of the two directories to ensure that your versioned copy is a duplicate of the original.
Check if your module has init.py
As George said check if module is on python path (import sys and print sys.path)
