A upload file is 0byte on django - python

My webserver symbolic linked another server. But a uploaded file was 0 byte when I uploaded file. It was work well before (I used just web server directory)
I don't have any idea dealing with this problem. Does anybody have a trouble like this problem on NFS?
In addition, It works well if I use on Python console.
Thanks,

I found a problem. It was django problem with NFS.
If you have same trouble, check this URLs.

How to fix image is not showing in heroku deployed django app

I have a Blog created with Django 3.x. When I run the project on my local server then it works fine. So, I deployed my project to heroku and here is the link bblog-shovon.herokuapp.com/. Then the project was working fine. My project git link https://git.heroku.com/bblog-shovon.gitThen I created a post and then I gave it a thumbnail and finally everything was fine. But, After sometime when i revisit the site then every image were gone. I didn't found them. And when I tried to open the image on another tab then it shows this Error message screenshot. When I am writing this question then I created a new post and after publishing this this posts image is working. But, older image is not working.
Then, How can i fix this problem? Please help me!!
Heroku flushes the filesystem to the latest commit. So you will have to use third-party plugins such as AWSBucket, etc.
With Heroku the filesystem is not persisted so you will lose media files occasionally. Use S3 or some other provider to store your user-uploaded media (also your static files if you want, otherwise use whitenoise). Django-storages makes it very easy.

Large Uploads in Django

I am working on a cookiecutter-django project that requires users to be able to upload files in the .5-1gb size range. From what I understand when uploading files that are larger then 2.5Mbs django uses the TemporaryFileUploadHandler to first upload the file to the tmp directory and then to then transfer them to the media directory. However when I try to upload a larger file my site just hangs, I don't see any files come into the tmp directory, and I see no errors in the logs.
Is there some setting I need to turn on to instruct django to use the TemporaryFileUploadHandler? Or is there some way to possibly figure out where the site might be getting hung up? I am currently building out this project locally so I have full control over my environment.
I am using Python 3.4.5 and django 1.10
UPDATE 1
I have tested uploading files of 5mb, 10mb, 20mb, and 30mb they all upload fine. The file I am having issues with is 873mb.
UPDATE 2
After more debugging I have found that when up loading a large file to my site it gets as far as the get_form method on my view class. After that I am not sure what is called. I have been slowly adding logs at each step in the hopes of figuring out where it is stuck.

django remote access basics

i have scripts producing outputs and other scripts reading these. All data should be read/written from/to a database on a server with corresponding information from multiple remote terminals.
I felt like django seems to be a nice solution.
Unfortunately the documentation and examples are only about setting up the data base and accessing it locally or via a browser. I get the impression that django is not offering this since i can not find anything about it and i was searching a lot.
Could someone help or link some examples how to write/read to the database on a server from an other machine?
Cheers,
Daniel
In the end, I figured out with the help of this!

PDFQuery + files on server

I'm trying to search for text string, say "can be", in document which is located on 'https://developer.apple.com/library/ios/documentation/ides/conceptual/AppDistributionGuide/AppDistributionGuide.pdf'
For this purpose I'm using PDFQuery. Initially I downloaded the pdf on my machine and did my code. It is working perfect. But when I tried to input the server url in file location it is showing me error. I know the PDFQuery library is developed to work on local machines.
Is there any way that I can figure out something and fix my problem. This is part of my course project and the pdf search module that I am supposed to develop is to be deployed on IBM Bluemix and run it from there. Only this part is pending in my project. Any help is appreciated.
Thank you in advance.
Break the problem into two bits.
i) download the file.
ii) process the file.
Here's some help with step i)

Deploying Django on an apache server

I am new to web development. So be gentle. AND thanks in advance.
I am developing on windows env. and deploying on a linux server w/ Python 2.6.2 installed.
Running apache2.2 as Virtual Host, and I am using mod_wsgi. I plan to serve media files from the same Virtual Host.
I have a django site and I am now ready to deploy. I am stuck, and every site I go to seems to be outdated/incomplete/overmyhead.

...only 2 links as for the newbness
The top link seems to be what I need yet I am still confused on these things:
What does the file structure look like on the server
I cannot change/edit server files myself, I rely on the dba for that
I have django.wsgi, and django.wsgi~, where do those go?
Where do I put my project in relation to those wsgi files?
The httpd.conf file is something that the server has on it? or do I create another?
Do I need to put django in any way shape or form on the server? If so where? And what about the packages like registration, defaults?
Again sorry for the newbness, I have been banging my head for 2 weeks on this.
Any help/links will be greatly appreciated unless they link me to the django-docs. I have read those...A LOT! thanks
Also go read:
http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango
and watch:
http://code.google.com/p/modwsgi/wiki/WhereToGetHelp?tm=6#Conference_Presentations
The latter includes Django examples and talks a bit about locations, permissions etc.
The first of these is even linked to in the document in the Django documentation.
It doesn't matter where the files go. They just have to be readable/executable by the user that the web server is running under.
I don't know what you mean by django.wsgi~, that sounds like a backup file created by your editor - you don't need that.
Yes the httpd.conf is the configuration file for Apache. Some distributions (eg Debian and Ubuntu) split this up into separate files for each site that the server runs. If your administrator is the only one who can edit files, he will know about this already.
Yes, you need Django, and any third-party packages.

An easier option for you while you are learning this is not to really have to many expenses.
I could also suggest you take a look at Heroku - allows you to easily deploy your applications in minutes.
Up until recently they only supported RoR and they have brought in support for Django and Python - they have some really well documented tutorials as well.
I hope this helps
Heroku Django / Python tutorial
I have written up an simple deployment guide for django applications it can be found here. It goes all the way from project setup and deployment. I also have references setup. I honestly believe it answers all your questions, I would give it a look.
Goodluck.
