Hi all,
I'm struggling with this problem for days. When trying to upload a file using a
FileField, the form doesn't post the file data to the server. It works
perfectly if you use a text field, but for some reason it doesn't recognize the
file, as it doesn't show up on request.FILES, or request.POSTS.
MEDIA_ROOT and MEDIA_URL configuration:
MEDIA_ROOT = '/home/grove/pootleImages/'
MEDIA_URL = '/pootleImages/'
get_unit_context decorator in decorators.py:
def get_unit_context(permission_codes):
def wrap_f(f):
@wraps(f)
def decorated_f(request, uid, *args, **kwargs):
unit = get_object_or_404(
Unit.objects.select_related("store__translation_project",
"store__parent"),
id=uid,
)
_common_context(request, unit.store.translation_project,
permission_codes)
request.unit = unit
request.store = unit.store
request.directory = unit.store.parent
return f(request, unit, *args, **kwargs)
return decorated_f
return wrap_f
My forms.py method:
def unit_image_form_factory(language):
image_attrs = {
'lang': language.code,
'dir': language.direction,
'class': 'images expanding focusthis',
'rows': 2,
'tabindex': 15,
}
class UnitImageForm(forms.ModelForm):
class Meta:
fields = ('image',)
model = Unit
# It works if using a CharField!
#image = forms.CharField(required=True,
# label=_("Image"),
# widget=forms.Textarea(
# attrs=image_attrs))
image= forms.FileField(required=True, label=_('Image'),
widget=forms.FileInput(
attrs=image_attrs))
def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
super(UnitImageForm, self).__init__(*args, **kwargs)
def save(self):
super(UnitImageForm, self).save()
return UnitImageForm
My models.py snippet:
class Unit(models.Model, base.TranslationUnit):
# ...
# ...
# It works if using a TextField!
#image = models.TextField(null=True, blank=True)
image = models.FileField(upload_to=".", blank=True, null=True)
# ...
# ...
My urls.py snippet:
url(r'^xhr/units/(?P<uid>[0-9]+)/image/?$',
'image',
name='pootle-xhr-units-image'),
My views.py method:
@require_POST
@ajax_required
@get_unit_context('translate')
def image(request, unit):
"""Stores a new image for the given ``unit``.
:return: If the form validates, the cleaned image is returned.
An error message is returned otherwise.
"""
# Update current unit instance's attributes
unit.uploaded_by = request.profile
unit.uploaded_on = timezone.now()
language = request.translation_project.language
form = unit_image_form_factory(language)(request.POST, request.FILES,
instance=unit,
request=request)
if form.is_valid():
form.save()
context = {
'unit': unit,
'language': language,
}
t = loader.get_template('unit/image.html')
c = RequestContext(request, context)
json = {'image': t.render(c)}
rcode = 200
else:
json = {'msg': _("Image submission failed.")}
rcode = 400
response = simplejson.dumps(json)
return HttpResponse(response, status=rcode, mimetype="application/json")
My HTML template for the image upload:
<div id="upload-image">
<form enctype="multipart/form-data" method="post" action="{% url
'pootle-xhr-units-image' unit.id %}" id="image-form">
<input type="file" name="image" id="id_image" />
<p><input type="submit" value="{% trans 'Upload' %}" /></p>
</form>
</div>
When the form is instantiated, request.POST does not return the file browsed by
the user, neither request.FILES. form.errors just returns "This field is
required" The form object returns the following:
<tr><th><label for="id_image">Image:</label></th><td><ul
class="errorlist"><li>This field is required.</li>
</ul><input lang="pl" rows="2" name="image" id="id_image" type="file"
class="images expanding focusthis" dir="ltr" tabindex="15" /></td></tr>
And when the user clicks the submit button, the following POST error occurs:
"POST /xhr/units/74923/image HTTP/1.1" 400 35
I could bypass it by including required=False to the image property, but the
file is not posted anyway.
Thank you,
Alex
