  • Reading file data during form's clean method

    - by Dominic Rodger
    So, I'm working on implementing the answer to my previous question. Here's my model: class Talk(models.Model): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) Here's my form: class TalkForm(forms.ModelForm): def clean(self): super(TalkForm, self).clean() cleaned_data = self.cleaned_data if u'mp3' in self.files: from mutagen.mp3 import MP3 if hasattr(self.files['mp3'], 'temporary_file_path'): audio = MP3(self.files['mp3'].temporary_file_path()) else: # What goes here? audio = None # setting to None for now ... return cleaned_data class Meta: model = Talk Mutagen needs file-like objects - the first case (where the uploaded file is larger than the size of file handled in memory) works fine, but I don't know how to handle InMemoryUploadedFile that I get otherwise. I've tried: # TypeError (coercing to Unicode: need string or buffer, InMemoryUploadedFile found) audio = MP3(self.files['mp3']) # TypeError (coercing to Unicode: need string or buffer, cStringIO.StringO found) audio = MP3(self.files['mp3'].file) # Hangs seemingly indefinitely audio = MP3(self.files['mp3'].file.read()) Is there something wrong with mutagen, or am I doing it wrong?

  • How do I make log4j create log files on demand only?

    - by Mirvnillith
    We have a modular application where modules have their own log4j logs (i.e. communication log and error log). The appenders and categories for these are all configured in the core log4j XML, but not all modules are always installed. The DailyRollingFileAppender creates its file regardless of use and that exposes the full set of modules although not present and as some of them are customer specific we'd like to hide logs not in use. Is there a way to make DailyRollingFileAppender create its file on first use instead of automatically at startup?

  • Handling extra newlines in csv files parsed with Python?

    - by rmihalyi
    I have a CSV file that contains extra newlines in some fields, e.g.: A, B, C, D, E, F 123, 456, tree , very, bla, indigo I tried the following: import csv catalog = csv.reader(open('test.csv', 'rU'), delimiter=",", dialect=csv.excel_tab) for row in catalog: print "Length: ", len(row), row and the result I got was this: Length: 6 ['A', ' B', ' C', ' D', ' E', ' F'] Length: 3 ['123', ' 456', ' tree'] Length: 4 [' ', ' very', ' bla', ' indigo'] Does anyone have any idea how I can quickly remove extraneous newlines? Thanks!

  • Why does Perl's Devel::LeakTrace::Fast point to blank files and evals?

    - by kt
    I am using Devel::LeakTrace::Fast to debug a memory leak in a perl script designed as a daemon which runs an infinite loop with sleeps until interrupted. I am having some trouble both reading the output and finding documentation to help me understand the output. The perldoc doesn't contain much information on the output. Most of it makes sense, such as pointing to globals in DBI. Intermingled with the output, however, are several leaked SV(<LOCATION>) from (eval #) line # Where the numbers are numbers and <LOCATION> is a location in memory. The script itself is not using eval at any point - I have not investigated each used module to see if evals are present. Mostly what I want to know is how to find these evals (if possible). I also find the following entries repeated over and over again leaked SV(<LOCATION>) from line # Where line # is always the same #. Not very helpful in tracking down what file that line is in.

  • FileSystemWatcher surpassing Active Directory restrictions

    - by DevexPP
    While experimenting with FileSystemWatcher, I've found out that it somehow surpasses Active Directory's restrictions to files and folders, and will raise change events with information about what has changed in files and folders that you don't even have access to. I have two questions about that: 1) Why does this happen ? 2) Is this a problem in the AD configuration ? how do I fix it ? 3) Is there any way to gather these files, or even create a FileSystemInfo of them to get more info about the files (not only the changes made on them) ? As far as I've tried, only the FileSystemWatcher immune to the restrictions, I can't run any other thing over it, here's a list of what I've tried: File.Exists Directory.Exists FileInfo instance on found files DirectoryInfo instance on found files File.Copy File.Delete

  • Reducing number of include files to reduce server load/speed up site?

    - by rein
    You can reduce the number of HTTP requests to speed up your site, such as css sprite images. I'm wondering does reducing the number of php includes/requires also speed up your site or reduce server load? For example, I have a index.php with <?php include './file.php'; ?> If instead I copy and paste the code from file.php and just put it into index.php, thus removing the include code, would it reduce the server load? This might make things less organized, but if it does reduce server load I might need to do that. For a small to medium sized site, I assume there might not be a difference, but how about for high traffic sites? Thanks in advance.

  • Can log4net appenders be defined in their own XML files?

    - by ladenedge
    I want to define a handful of (ADO.NET) appenders in my library, but allow users of my library to configure the use of those appenders. Something like this seems to be what I want: XmlConfigurator.Configure(appenderStream1); XmlConfigurator.Configure(appenderStream2); XmlConfigurator.Configure(); But that doesn't seem work, in spite of the debug output containing messages like this: Configuration update mode [Merge]. What is the right way to do this? Or, is there an alternative to asking users to duplicate large chunks of XML configuration?

  • I really need help with Delphi... text files and arrays with sorting?

    - by DTB
    I have read a text file (of names) into an array and I need how to sort those names into alphabetical order and display that in a rich edit? Please give me the code from this point onwards: readln(myfile,arr[i]); 'myfile' is the text file and 'arr' is the array of string. Also, I have declared 'i' as an integer even though it is a array of string. Is that OK?

  • Can you use Ant to Build/Modify XML files?

    - by user369701
    I am quite new to ant and have been looking at the tasks. I am trying to generate an xml file. Do I need to call an external process or does ant have some way to do this? It could be as simple as sending a string to a txt file and saving it as a .xml. Is it possible?

  • How to create an MSI package that installs no files and only executes some commands using Wix

    - by Sevas
    I am trying to create an MSI package that uses the AppCmd application to configure IIS7. It only has to execute some commands that call AppCmd. Some commands need to be called when installing, other commands need to be called when uninstalling. Here is what I have now: I have a property that points to AppCmd: <Property Id="APPCMD" Value="C:\Windows\system32\inetsrv\appcmd.exe" /> I have my custom actions: <CustomAction Id="UnlockHandlerSection" Return="check" Property="APPCMD" ExeCommand="unlock config /section:system.webServer/handlers" /> I have Custom elements that call the actions: <InstallExecuteSequence> <Custom Action="UnlockHandlerSection" After="InstallFiles">NOT Installed AND NOT PATCH</Custom> <InstallExecuteSequence> The problem with this is is that the commands are not called when I try to install the resulting MSI package. Could anyone please advise me on what I am doing wrong? Thank you!

  • Can I add Boost source+header files to my own (Open Source) project?

    - by rubenvb
    Is it allowed by the Boost License to just add the source code of the stuff I need to my project (accompanied by the license of course?). I couldn't find any "descriptive" confirmation. I would have seperate Include/boost and Source/boost directories for easy access. PS: Seeing as boost::filesystem is going into C++0x TR2, and lambda's are already in c++0x TR1, I don't see any reason to be juggling with C functions like realpath, getcwd and the like. They don't work well anyways...

  • Python Logging across multiple classes and files; how to configure so as to be easily disabled?

    - by mellort
    Currently, I have osmething like this in all of my classes: # Import logging to log information import logging # Set up the logger LOG_FILENAME = 'log.txt' logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG) This works well, and I get the output I want, but I would really like to have all this sort of information in one place, and be able to just do something like import myLogger and then start logging, and then hopefully be able to just go into that file and turn off logging when I need an extra performance boost. Thanks in advance

  • Visual Studio 2008 & Perforce. Where is my .vspscc files?

    - by P-P
    Hi, I use Visual Studio 2008 and Perforce. When I bind my project to perforce(File - Source Control - Change Source Control - Bind), Visual Studio complain like "~.vspscc File is not under source control". Should I create that file for myself, or is that file created by Visual Studio? If it is created by Visual Studio, why does it complain about it? Thanks in advance.

  • How should I handle header files in a bundle?

    - by ldiqual
    I want to develop a program that relies on plugins (here: loadable bundles) to work. Multiple plugins are asked to use the same AFNetworking ressource to make network requests. However, I don't know where to put AFNetworking and CustomPluginProtocol headers. Here is how my program structure looks like for now: MyApp.xcodeproj - AFNetworking - Header.h - Plugins - Plugin1.xcodeproj - PrincipalClass.m - Plugin2.xcodeproj - PrincipalClass.m - Classes - CustomPluginProtocol.h - MainClass.m Of course, every principalClass from PluginN complies to the CustomPluginProtocol. Do the headers have to be copied in each bundle ? Can I just include the main program AFNetworking headers from my plugins ? If so (and that's what I do for now), I don't have any completion. How can I get it ? Edit Ok, so maybe I wasn't clear in my question. I want my plugins to use sources from the main application, let's say CommonClass.m and CommonClass.h. Do the plugins need CommonClass.h in their bundle, and if not, how do I enable completion when I'm in the plugin scope ?

  • Some stupid warnings

    - by thetna
    I have a number of C source files(both .c and .h files). header files contains a number of functions. Out of those functions, only partially are used in a source .C file.Suppose a.h,b.h are header files and a.c and b.c are .c files. a.h is included in a.c. But only a number of functions those are in a. h are used and rest are not used. After compilation I find following warnings: function XXXX defined but not used. But those XXXX functions which are not used in a.c are used in b.c. So, i can't completely remove those functions too. So , i decided to make a separate file containing only those XXXX functions and included it wherever it is used.Doing this is creating multiple number of header files. Can anybody please suggest me to some effective way to solve this problem.

    I must be doing something stupid.

  • Hudson results one step behind

    - by kaerast
    I'm using the filesytem plugin for Hudson, and when a build happens it looks for new/modified files, copies them to the Workspace, runs tests using Rake, and then publishes those junit xml result files. However, the updated junit xml result files don't get pushed to the workspace until the next build. This means that when the publishing of the junit xml result files happens, it's always one step behind. And this means I need to run a build twice before the results show. The Rake task is creating the junit xml files in the project directory. I've tried outputting to the workspace directory, but it seems to make things worse and the results don't get published at all. Am I doing something fundamentally wrong here? Is there a simple way of getting those junit xml results pushed to the workspace so that the post-build "Publish JUnit test result report" actually runs against the newly created xml files?
