I am beginner in django . I would like to make an application that allows a user to record examinations and related images.
So i try to uploading multiple images in Django for a single post according this topic http://qasimalbaqali.com/uploading-multiple-images-in-django-for-a-single-post/.
But nothing happens when I press the button I explain my models. A document is a generic class. An exam is a document, a document contains files.
class Document(models.Model):
class Meta:
db_table = 'Document'
slug = models.SlugField(max_length=100)
user = models.ForeignKey(User)
level = models.ForeignKey(ClassLevel, null=False, default=1)
school = models.ForeignKey(School, null=False, default=1)
nb_views = models.IntegerField(default=0)
name = models.CharField(max_length=100)
matter = models.ForeignKey(ClassTopic, null=False, default=1)
status = models.IntegerField(choices=DOCUMENT_STATUS, default=1)
creation_date = models.DateTimeField(auto_now_add=True)
deletion_date = models.DateTimeField(auto_now_add=False, default=None, null=True)
def __unicode__(self):
return self.name + " (" + str(self.status) + ") " + self.school.name
class DocumentFile(models.Model):
class Meta:
db_table = 'DocumentFile'
file = models.FileField(upload_to="photo/", null=True)
document = models.ForeignKey(Document)
def __unicode__(self):
return self.file
class Exam(Document):
class Meta:
db_table = 'Exam'
year_exam = models.IntegerField(choices=EXAM_YEAR_CHOICES, default=1)
mock_exam = models.IntegerField(choices=EXAM_TYPE, default=1)
def __unicode__(self):
return self.name + " " + self.matter
I create two forms. For exam and for file.
class UploadFileForm(ModelForm):
#description = forms.CharField(max_length=30)
file = forms.FileInput()
helper = FormHelper()
helper.form_id = 'file-input'
helper.form_show_labels = False
helper.layout = Layout(PrependedText('file', "", placeholder=""))
#helper.layout.insert(1, HTML("<input type='file' class='file' multiple data-show-upload='false' data-show-caption='true'>"))
class Meta:
model = DocumentFile
fields = ('file',)
#exclude = ("file_type", "file_path", "document")
class CreateExamForm(forms.ModelForm):
helper = FormHelper()
helper.form_id = 'CreateExam'
helper.form_show_labels = False
helper.layout = Layout(
PrependedText("matter", "", ""),
PrependedText("level", "<small class='text-warning'>Selectionner la classe. </small>", ""),
PrependedText("school", "<pre><small>Selectionner l\'établissement. </small></pre>", css_class="selectpicker"),
PrependedText("year_exam", ""),
PrependedText("mock_exam", ""))
class Meta:
model = Exam
exclude = ("slug", "user", "nb_views", "name", "status", "creation_date", "deletion_date")
My view
def createexam(request):
# Creation du formulaire + upload des images
doc_form = CreateExamForm(auto_id=True)
# Création du formset avec n itération : extra=2
file_form_set = modelformset_factory(DocumentFile, form=UploadFileForm, extra=1)
# Récupération du formulaire géré par le mécanisme formset
#formset = sortedfilesform()
if request.method == "POST":
doc_form = CreateExamForm(request.POST)
files_form = file_form_set(request.POST, request.FILES, queryset=DocumentFile.objects.none())
if doc_form.is_valid() and files_form.is_valid():
doc_save = doc_form.save(commit=False)
doc_save.user = request.user
for fileform in files_form.cleaned_data:
image = fileform['file']
one_image = DocumentFile(document=doc_save, file_value=image)
one_image.save(commit=False)
transaction.commit()
msg = FORM_PROPERTIES.FORM_EXAM_STORED.replace("user", request.user.nickname)
messages.add_message(request, messages.SUCCESS, msg)
form = LoginForm()
context = {'form': form}
return render_to_response(template_name='login.html', context=context, context_instance=RequestContext(request))
else:
messages.add_message(request, messages.SUCCESS, FORM_PROPERTIES.FORM_EXAM_ERROR)
context = {'doc_form': doc_form, 'file_form_set': file_form_set, }
return render(request, 'createexam.html', context)
else:
context = {'doc_form': doc_form, 'file_form_set': file_form_set, }
return render(request, 'createexam.html', context)
my url.py
urlpatterns = [
# Examples:
url(r'^$', home, name='home'),
url(r'^admin/', include(admin.site.urls)),
url(r'^$', home),
url(r'^home', home),
url(r'^login', login),
url(r'^logout', logout),
url(r'^register$', register),
url(r'^createexam$', createexam),
url(r'^account/reset_password', reset_password, name="reset_password"),
]
My template is simple
<div id="login-overlay" class="modal-dialog">
<div class="row">
<div class="panel panel-info" >
<div class="panel-heading">
<div class="panel-title">Créer un examen</div>
</div>
<div class="panel-body" >
<div class="col-sm-12">
<form id="post_form" method="POST" action='.'
enctype="multipart/form-data">
{% csrf_token %}
{% for hidden in doc_form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in doc_form %}
{{ field }} <br />
{% endfor %}
{{ file_form_set.management_form }}
{% for form in file_form_set %}
{% crispy form %}
{% endfor %}
<input type="submit" value="Add recipe" class="submit" />
</form>
</div>
</div>
</div>
</div>
Everything seems good form me. But my submit does no think. I 'm on it for two days. I read and tried many things. Does anybody can help me please (Sorry for my english)
