Hi, Can someone teach me how to parse a file uploaded to GAE?
I am writing a feature that users can upload a .csv file, and save
data into the data model. I have already implemented the uploading,
see the link below:
http://gae-hejibo.appspot.com/TestUpload
But I do not know how to parse it, and save in my data model. Below is
my html and processing code. I can upload a csv file, but the data in
the csv is not saved into the data model. Can someone teach me what's
wrong with my code, and how should I do? Thanks!
------------------html file code--------------------
<form name="uploadform">
<div>
</p>CSV File(Comma Separated Value) File*: </p>
<input type="file"
name="uploadfilename"/>
<input type="submit" value="Upload"></div>
</form>
------------------processing code--------------------
class TestUpload(webapp.RequestHandler):
'''add item using .csv file'''
def get(self):
path =
os.path.join(os.path.dirname(__file__),'template','TestUpload.html')
self.response.out.write(template.render(path, {}))
def post(self):
fileReader = open(self.request.get('uploadfilename'))
csv_file=self.request.get('uploadfilename')
fileReader = csv.reader(csv_file.split("\n"))
for row in fileReader:
cell = row.split('\t')
fourchoice = FourChoices()
fourchoice.description = cell[0]
fourchoice.choiceA = cell[1]
fourchoice.choiceB = cell[2]
fourchoice.choiceC = cell[3]
fourchoice.choiceD = cell[4]
fourchoice.a = cell[5]
fourchoice.b = cell[6]
fourchoice.c = cell[7]
fourchoice.answer = cell[8]
fourchoice.put()
path =
os.path.join(os.path.dirname(__file__),'template','debug.html')
self.response.out.write(template.render(path,
{'description':'fileupload'}))
