I created a ms-word document using MailMerge in django. It´s worked ok.
Right now, i´d like to show this file on screen. I write the code bellow, but it didn´t work.
views.py
with open(file_path) as doc:
response = HttpResponse(doc.read(), content_type='application/ms-word')
response = HttpResponse(template_output)
response['Content-Disposition'] = 'attachment;filename=var_nomdocumento_output'
error:
[Errno 13] Permission denied: 'C:\\GROWTHTECH\\Projetos\\blockchain\\media_root/procuracao'
You forgot to provide the binary open mode. It can be r open for reading (default) w open for writing, truncating the file first, b for binary mode.
so In our case: It will be rb
file_path = 'path/path/file.docx'
with open(file_path,'rb') as doc:
response = HttpResponse(doc.read(), content_type='application/ms-word')
# response = HttpResponse(template_output)
response['Content-Disposition'] = 'attachment;filename=name.docx'
return response
No browsers currently render Word Documents as far as I know. So your file will be automatically downloaded whatever the parameter is: 'attachment;filename="file_name"' or 'inline;filename="file_name"'

I have written code for downloading a file through an API. It works fine as I can see. The file size is the same. But the file has no longer a default file icon. I am pretty new at this and maybe I am doing something wrong. I am reading the file as I would for a standard textfile and saving it in the same way with the binary option. So how can the files be same size and still something seems to be missing in the downloaded file? Is there a better way to download files?
This is the code on the server:
file_location = 'static/File.pkg'
try:
with open(file_location, 'rb') as f:
filex_data = f.read()
response = HttpResponse(filex_data, content_type='application/octet-stream')
response['Content-Disposition'] = 'attachment; filename="File.pkg"'
return response
This is the code on my local computer:
url = 'http://myServer/waprfile/'
x = requests.get(url, data=data, headers=headers)
f = open("TheNewFile.pgk", "ab")
f.write(x.content)
f.close()
I have a website that has a button. When it's clicked, it returns a number of pandas dataframers into an excel file and returns that excel file automatically as download.
It seems to work ok, except when I open the file, it seems to be corrupted. It asks if some of the tabs should be recovered. I'm using the code below. Any suggestions are appreciated what could be the cause for this.
import io
from flask.helpers import make_response
from pandas.io.excel import ExcelWriter
output = io.BytesIO()
writer = ExcelWriter(output)
dfs = [df1,df2....]
tabs ['tab1','tab2',....]
for df, tab_name in zip(dfs, tab_names):
df.to_excel(writer, tab_name)
writer.close()
resp = make_response(output.getvalue())
resp.headers['Content-Disposition'] = 'attachment; filename=output.xlsx'
resp.headers["Content-type"] = "text/csv"
return resp
You'll need to to add
output.seek(0)
after you close the writer.
You might also find it easier to write
return send_file(output, attachment_filename="output.xlsx", as_attachment=True)
(after importing send_file from flask)
I am receiving an http request from a desktop application with a screenshot. I cannot speak with the developer or see source code, so all I have is the http request I am getting.
The file isn't in request.FILES, it is in request.POST.
#csrf_exempt
def create_contract_event_handler(request, contract_id, event_type):
keyboard_events_count = request.POST.get('keyboard_events_count')
mouse_events_count = request.POST.get('mouse_events_count')
screenshot_file = request.POST.get('screenshot_file')
barr2 = bytes(screenshot_file.encode(encoding='utf8'))
with open('.test/output.jpeg', 'wb') as f:
f.write(barr2)
f.close()
The file is corrupted.
The binary starts like this, I don't know if that helps:

Also, if I try to open the image with PIL, I get the following error:
from PIL import Image
im = Image.open('./test/output.jpg')
#OSError: cannot identify image file './test/output.jpg'
Finally, I managed to touch the code in the other hand, the 'filename' was missing in the header and for that reason I was getting the file in the POST instead of in the FILES dictionary.
I cannot find any example on how to attach files(pdf) that are within my root folder of the site in python (google app engine) send_mail function.
url_test = "https://mywebsite.com/pdf/test.pdf"
test_file = urlfetch.fetch(url_test)
if test_file.status_code == 200:
test_document = test_file.content
mail.send_mail(sender=EMAIL_SENDER,
to=['test#test.com'],
subject=subject,
body=theBody,
attachments=[("testing",test_document)])
Decided to try it with EmailMessage:
message = mail.EmailMessage( sender=EMAIL_SENDER,
subject=subject,body=theBody,to=['myemail#gmail.com'],attachments=
[(attachname, blob.archivoBlob)])
message.send()
The above blob attachment is successfully sending however attaching a file with relative path always says "invalid attachment"
new_file = open(os.path.dirname(__file__) +
'/../pages/pdf/test.PDF').read()
message = mail.EmailMessage( sender=EMAIL_SENDER,
subject=subject,body=theBody,to=['myemail#gmail.com'],attachments=
[('testing',new_file )])
message.send()
In debugging I have also tried to see if the file is being read by doing this:
logging.info(new_file)
It seems to be reading the file as it outputs some unicode characters
Please help why am I not able to attach a PDF while I can attach a blob
When calling the attachments, the File type has to be indicated on the file title, for example attachments= [('testing.pdf',new_file )]). View this link
I looked at the various questions similar to mine, but I could not find anything a fix for my problem.
In my code, I want to serve a freshly generated excel file residing in my app directory in a folder named files
excelFile = ExcelCreator.ExcelCreator("test")
excelFile.create()
response = HttpResponse(content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename="test.xls"'
return response
So when I click on the button that run this part of the code, it sends to the user an empty file. By looking at my code, I can understand that behavior because I don't point to that file within my response...
I saw some people use the file wrapper (which I don't quite understand the use). So I did like that:
response = HttpResponse(FileWrapper(excelFile.file),content_type='application/vnd.ms-excel')
But then, I receive the error message from server : A server error occurred. Please contact the administrator.
Thanks for helping me in my Django quest, I'm getting better with all of your precious advices!
First, you need to understand how this works, you are getting an empty file because that is what you are doing, actually:
response = HttpResponse(content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename="test.xls"'
HttpResponse receives as first arg the content of the response, take a look to its contructor:
def __init__(self, content='', mimetype=None, status=None, content_type=None):
so you need to create the response with the content that you wish, is this case, with the content of your .xls file.
You can use any method to do that, just be sure the content is there.
Here a sample:
import StringIO
output = StringIO.StringIO()
# read your content and put it in output var
out_content = output.getvalue()
output.close()
response = HttpResponse(out_content, mimetype='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename="test.xls"'
I would recommend you use:
python manage.py runserver
to run your application from the command line. From here you will see the console output of your application and any exceptions that are thrown as it runs. This may provide a quick resolution to your problem.
