First off, sorry for the lack of code; verbiage is the only thing that I can think of using to describe the problem
I have a link which when I run it using:
webbrowser.open('http://www.MyLink&ticker=IBM')
automatically downloads IBM data for me. The file is automatically named download.csv
The next time I run this it tries to use the same name and therefore I get a file download(1).csv and so on.
There are 2 things I wish to accomplish.
Open the file download.csv and rename it ticker_Date.csv where ticker would be IBM or GE, etc and date is the previous biz day. This way I avoid file names download(1) download(2) etc and can actually have the file name associated with the ticker (IBM for example) and the trade date the data is from
Not open 20 web browser pages if I request 20 different tickers by closing the webbrowser after the download is complete.
I tried:
with urllib.request.urlopen(url) as response, open(file_name, 'wb') as out_file:
shutil.copyfileobj(response, out_file)
I don't seem to be able to get this to work. To be clear, when I enter the url a download automatically takes place. All of the resources I have seen have referenced "downloading" a file with a "file_Name", but this is automatically done in my case. I don't have a file name per-say
thanks for any help

My app works with user txt-files (create, change, delete) inside any user-selected folder. I just internally store the bookmark to get access to that user-selected folder and files.
Now, with macOS Catalina when the source folder is inside iCloud Drive, system still allows me to create and edit files. But doesn't allow to trash one. When I try to do it via [[NSFileManager defaultManager] trashItemAtURL: ... ] I get the following error:
Error Domain=NSCocoaErrorDomain
Code=3328
"<filename> couldn’t be moved to the trash
because the volume “<APFS volume name>”
doesn’t have one."
UserInfo={
NSURL=file:///... <filepath>.txt,
NSUserStringVariant=Trash
}
Note: this only happens when the app is sandboxed.
Any ideas how to get the file trashed correctly?
P.S. I know there is a NSWorkspace recycle... method, but it makes an extra deletion prompt that is not suitable for me.
P.P.S. I am still able to use [[NSFileManager defaultManager] removeItemAtURL: ...] method, but I need the target file to be restorable in case user changes his mind.
Ok. Looks like it's a rare case. But if you've got into the same situation, here is what I've ended up with:
There is a deprecated function - FSMoveObjectToTrashSync - that still works just fine. It saved my ass for now.
How to create log file with custom file name in cakephp 2.5.1.
I am written following code
$this->log("Data : ".print_r($this->data,true),'debug');
It create's debug.log file in tmp/log folder but when I write custom name like
$this->log("Data : ".print_r($this->data,true),'data');
This code do not create any log file. My Question is how to create log file with custom name?
Same answer as for the other question: Start reading the manual. A huge part of the profession is to read documentation.
Changed in version 2.5.
CakeLog does not auto-configure itself anymore. As a result log files
will not be auto-created anymore if no stream is listening. Make sure
you got at least one default stream set up, if you want to listen to
all types and levels. Usually, you can just set the core FileLog class
to output into app/tmp/logs/:
I am trying to make a new file format for music. It needs to be a file that actually stores multiple audio files, for example a zip file. I am looking for a way to turn the zip file into this new file format. However, I still want to use id3 tags with these new files. I was wondering how I can make this new file format which is one file that holds multiple audio files, but still contains overall id3 tags for that one file, so that I can load it into my mobile applications.
Any help/recommendations would be appreciated.
Cheers,
AJ
The problem with creating your own new file format is that only you can use it. Until you convince lots of other people that it is a useful new format, no one else will have the tools to be able to do anything with the files you create.
For existing music player programs to be able to handle a new file format, you must write a CODEC for your file format in that player's plug-in style. Probably more than one plug-in as your file format is both a container of music and a catalog as well.
One alternative to creating a new file format is to put the MP3 files you have into a new MP3 file with each old file a new TRACK in the new file. Be sure to set each new tracks start time to be after the sum of all previous tracks play duration, so they don't step on each other. Merge the metadata about each file into the metadata of the new file. This might work OK for collections with lots of common metadata (like same artist), but might not work very well if the metadata is extremely varied.
Another alternative is to convert them to CDA format and put then into an Audio-CD image file, just as if you had burned them to a CD.
A third alternative is to put your files into an SQLite database file. Your metadata from each MP3 file fill in records, and you have your choice of leaving the MP3 file external and just linking to it, or storing the blob of your MP3 file in the DB as well. If you do store the blobs, then the SQLite database file is a single file that contains everything you put in it.

Don't create new formats unless you really really have a very good reason to do so.
Its sounds like Matroska can do anything you need. But in contrast to your own format you and other developers will have a bunch of ready to use tools to work with the format. This includes editors, players,... Additionally it you can leave making initial engineering errors to other people.
If you really really want to create your own format: Either just put your audio files that support id3 tags into your zip file, or create a meta file, for example in XML format, into your zip files as well, that contains the meta information that you want to be included.
I am using the Drupal 7 Migrate module to create a series of nodes from JPG and EPS files. I can get them to import just fine. But I notice that when I am done importing them if I look at the nodes it creates, none of the attached filefield and thumbnail files contain filename information.
Upon inspecting the file_managed table I see that both the filename and filemime fields are empty for ONLY the files that I attached via the migrate module. This also creates an issue with downloading the files.
Now I think the problem has to do with the fact that I am using "file_link" instead of "file_copy" as the file operation I specify. The problem is I am importing around 2TB (thats Terabytes) of image files. We had to put in a special request with Rackspace just to get access to that much disk space on our server. So I can't go around copying from one directory to the next because of space issues. So "file_link" seems like the obvious choice.
Now you probably want to see how I am doing this exactly, so here is the code snippet:
$jpg_arguments = MigrateFileFieldHandler::arguments(NULL,
'file_link', FILE_EXISTS_RENAME, 'en', array('source_field' => 'jpg_name'),
array('source_field' => 'jpg_filename'), array('source_field' => 'jpg_filename'));
$this->addFieldMapping('field_image', 'jpg_uri')
->arguments($jpg_arguments);
As you can see I am specifying no base path (just like the beer.inc example file does). I have set file_link, the language, and the source fields for the description, title, and alt.
It is able to generate thumbnails from the JPGs. But still missing those columns of data in the db table. I traced through the functions the best I could but I don't see what is causing this. I tried running the uri in the table through the functions that generate the filename and the filemime and they output just fine. It is like something is removing just those segments of data.
Does anyone have any idea what this could be? I am using the Drupal 7 Migrate module version 2.2. It is running on Drupal 7.8.
Thanks,
Patrick
Ok, so I have found the answer to yet another question of mine. This is actually an issue with the migrate module itself. The issue is documented here. I will be repealing this bounty (as soon as I figure out how).
I have set .jpg file associated to my own program. I want to add the context menu to .jpg files, so I set the entry of HKCR.jpg\shell\open\command to "myProg.exe %1". After associating, there will be an item on the top of the context menu saying "Open image with myprog". This works right when I select a single .jpg file, but when I selected more than one file and click the top item of the context menu, nothing happended. How can I solve the problem?
Thank you very much
Each selected file will be sent to a new instance of your application. Your application should check if a previous version exists, or not. If a previous instance exists, it should sent its parameters to it (e.g. using Windows Messages) and then terminate.
Another approach is to use DDE (Dynamic Data Exchange), an old method used by Shell to send all files to one instance of your program.
You might need double quotes around the "%1".
