I have managed to configure a system, using django, that allows me to
upload a file to my media-folder. I have (using simple-html) included a
drop-down menu that will specify parameters that will be considered when
processing the uploaded file in a pipeline.
<form action="{% url "list" %}" method="post" enctype="multipart/form-data">
<tr>
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.docfile.errors }}
{{ form.docfile }}
</p>
</tr>
<tr>
<th>Genome Dataset</th>
<TD WIDTH = 80% ALIGN=left VALIGN=top>
<SELECT NAME='genome' ID='genome'>
<OPTION>All</OPTION>
<OPTION>Neanderthal</OPTION>
<OPTION>hg38 Human</OPTION>
<OPTION>Denisovan</OPTION>
</SELECT>
</tr>
<p><input type="submit" value="Upload"/></p>
</form>
I need to send the selected dropdown option to a text file. and I have
attempted to do so as follows in views.py. However. while the file uploads
to the media folder successfully, no text file manifests in the media
folder- which is needed.
def GenomesView(request):
if request.method == 'GET':
getgen = request.GET.get('genome')
content = ContentFile(getgen)
f = open(os.path.join(settings.MEDIA_ROOT, 'file.txt'), 'w')
myfile = File(f)
myfile.write(getgen)
myfile.close()
The location of the media folder is as below in settings.
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
Hence my question is how do I take the selected option forms the drop-down
and each time the file is uploaded to the site, the selection is sent to
text file that will be over-written for each new submission (acting as a
temporary storage for the selected option parameter i.e "Neanderthall" etc.
as seen in code above)?
We have also tested the "tempfile" module with a generic command to create
a temporary file within the app directory:
>>> with TemporaryFile() as f:
f.write('abcdefg')
f.seek(0) # go back to the beginning
print(f.read())
abcdefg
But this does not work either....
