Django Safe HTML escaping
Ive been using Django builtin template filter safe to display some HTML code from a view. It's been working ok, but now it behaves strangely and I'm not sure what is to blame, if the HTML has changed or if the filter tag has changed in a django update. The Html code is delivered from the application mediainfo and looks like this... b'<html>\r\n' b'\r\n' b'<head>\r\n' b'<META http-equiv="Content-Type" content="text/html; charset=utf-8" /></head>\r\n' b'<body>\r\n' b'<table width="100%" border="0" cellpadding="1" cellspacing="2" style="border:1px solid Navy">\r\n' b'<tr>\r\n' b' <td width="150"><h2>General</h2> In the template I am using the safe filter as per the documentation to display the html. {% for line in htmlcode %} {{ line|safe }} {% endfor %} The resulting HTML now displays like this - b'\r\n' b'\r\n' b'\r\n' b'\r\n' b'\r\n' b'\r\n' b'\r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' \r\n' b' … -
Django request.user is becoming empty after login using angularjs
I have Django and angularjs app running separately. I am able to login to system by using angularjs. however after login request.user in django gives empty data.

Django export objects to .xlsx file with xlsxwriter
I'm using xlsxwriter library to export Django objects to .xlsx file. It seems to partially work, because I'm getting an issue when the file is downloaded. I open it with Excel and this issue appears in a window popup : An error occurred while sending a command to the program Then, if I reopen the file with Excel loaded, it works. So why it doesn't work the first time ? My excel works fine because I don't have any issue with .xlsx file from internet or somewhere else. This is my code which let to generate the excel file : def export_categories_xls(request): output = io.BytesIO() book = xlsxwriter.Workbook(output) sheet = book.add_worksheet('Category List') row = 0 sheet.write(row, 0, 'name') objects = Category.objects.all() row += 1 for item in objects: print(item) sheet.write(row, 0, item.name) row += 1 book.close() # construct response output.seek(0) response = HttpResponse(output.read(), content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") response['Content-Disposition'] = "attachment; filename=test.xlsx" return response Thank you ;) -
Get request triggered by js
I will explain what functionality I need in my django app on this example: User see list of cars and click "detail" button next to nice Mazda3, this action redirects him to the other page with URL like www.myapp.com/cars/detail/mazda3 where he can see additional information about car loaded from database. Also if he access this URL directly it should work without previous js call. I'm begginer and my plan after some search is to in js function trigger GET request, including car model in url in urls.py map base of this url '/cars/detail/' to view function in views.py parse car model from url and render page Problem is that I'm not sure this is correct way or if I should choose different approach. Also is GET request necessary (I've read that synchronous request should not be triggered in js) or should I just redirect to wanted url? -
How to update django sql database with a python script running locally?
I am currently working on a project for which I have to publish constantly changing data though my application programming interface. I have set up the django rest-framework, the model required for the sql database, the serializer and everything is working perfectly. I have seen that new database entries may be made through the python shell. I have a local algorithm running which is constantly calculating new analytics. I would like to make the algorithm update the database like it can be done manually through the shell. I have searched the web and the official documentation but could not find any instructions on how I could write a python script which updates the database. Does anyone know how to do this and may point me to suiting documentation or a tutorial? Thanks a lot for your help. Kind regards Marcel -

Deploying Django on VPS but getting nginx 502 Bad Gateway: recv() failed (104: Connection reset by peer) while reading response header from upstream
I'm trying to deploy a Python3 Django project on a Digital Ocean droplet using one-click install for Django. I've uploaded everything and changed the files to what they should be (to my knowledge) but when I go to my site in my web browser, I get a page that says '502 Bad Gateway' from nginx. When I look in my error log, I get the following error: recv() failed (104: Connection reset by peer) while reading response header from upstream I'm not sure what this means exactly, so I'm hoping someone here can help. I have however changed the python command to run python3 because it was set up for python2 and an older version of Django. I've updated Django and dependencies. Are the any config files I should edit? Perhaps a python path for nginx? I'm a bit in over my head here, so any help is appreciated. Thanks! -
