form doesn't validate when trying to upload file

[mapapage]

Hi! It's my first time trying to achieve the ''file upload functionality' and I need your help. I'm working on a legacy db and I'm supposed to do the file upload in a table that gets created this way:

CREATE TABLE  "LICENCE" 
   (	"ID" NUMBER NOT NULL ENABLE, 
	"VEH_ID" NUMBER NOT NULL ENABLE, 
	"DTP_ID" NUMBER NOT NULL ENABLE, 
	"LICENCENO" VARCHAR2(50 CHAR) NOT NULL ENABLE, 
	"ISSUEDATE" DATE, 
	"STARTDATE" DATE, 
	"EXPIREDATE" DATE, 
	"DOCPATH" VARCHAR2(500 CHAR), 
	"CHECKFLAG" NUMBER(1,0) NOT NULL ENABLE, 
	 CONSTRAINT "LIC_PK" PRIMARY KEY ("ID") ENABLE, 
	 CONSTRAINT "LIC_DTP_FK" FOREIGN KEY ("DTP_ID")
	  REFERENCES  "DOCTYPES" ("ID") ENABLE, 
	 CONSTRAINT "LIC_VEH_FK" FOREIGN KEY ("VEH_ID")
	  REFERENCES  "VEHICLES" ("ID") ENABLE
   )
/
With inspectdb, I got this table:
class Licence(models.Model):
    id = models.DecimalField(unique=True, primary_key=True, max_digits=127, decimal_places=0)
    veh_id = models.ForeignKey(Vehicles, db_column='veh_id')
    dtp_id = models.ForeignKey(Doctypes, db_column='dtp_id')
    licenceno = models.CharField(max_length=200)
    issuedate = models.DateField(null=True, blank=True)
    startdate = models.DateField(null=True, blank=True)
    expiredate = models.DateField(max_length=2000, blank=True)
    docpath = models.CharField(max_length=200)
    checkflag = models.IntegerField()
    
    def __unicode__(self):
        return self.licenceno

How should I handle the upload?My thought after reading the file upload documentation was to modify the docpath to filefield. Is that the right practice?Because I tried it, and the form doesn't validate, I get the error "No file chosen". Can anyone guide me through this?Thank you..

I'm assuming you are using the forms.ModelForm for your model? Say LicenceForm?

class LicenseForm(forms.ModelForm):
    class Meta:
        model = License 

According to the doc you have to pass all relevant QueryDicts to the form __init__
when you are creating a bound instance. In a nutshell make sure your doing:

# The view function
def handle_upload(request):
    # Get request logic ...
    if request.method == "POST":
        form = LicenceForm(request.POST, request.FILES)
        if form.is_valid():
           #save input data
           form.save()
           #continue with other stuff

More on the docs: https://docs.djangoproject.com/en/dev/topics/http/file-uploads/#handling-uploaded-files-with-a-model

Yes, exactly I'm using a modelform and in my views I'm doing:

def upload(request):
    if "doc-form" in request.POST:
        docform = LicenceForm(data=request.POST, files=request.FILES)
        if docform.is_valid():
            docform.save()
            return render_to_response('bingo.html', locals(), context_instance=RequestContext(request)
    else:
        docform = LicenceForm()
    return render_to_response('upload.html', locals(), context_instance=RequestContext(request))

but it doesn't work!

I also include the right header in the form template and changed the directories in settings. I really can't sense the problem..

Also, don't forget the multi-part in your template: <FORM action="" enctype="multipart/form-data" method="post">

[mapapage]

as I say in my last reply, I include the multi part header and it doesn't work! :( What else I can try?

[Kurtis Mullins]

ahh, sorry I just saw something that might help. Try making this change:

docpath = models.CharField(max_length=200)

to:

docpath = models.FileField(...) # Check the docs for arguments to this Field. https://docs.djangoproject.com/en/dev/ref/models/fields/#filefield

I have it like this, with filefield, in my first question I'm just posting the generated model from inspectdb and underneath I'm saying that I change it to FileField..

[Kurtis Mullins]

Sorry about that. I accidentally over-looked where you mentioned that in your email.

Are you running this on a debug server? Also, can you try replacing your template code with a simple <form ....>{% csrf_token %}{{ form }}<input type="submit" /></form> and see if that makes any differences?

I'm running it on the django development server. I changed the header and it behaves  the same way. Is that expected or not?

I also tried print request.FILES and I get <MultiValueDict: {}>, but after i tried print request.raw_post_data and it seems that the name of the file that i try to upload is included in the post data. I'm running out of other ideas!

After some testing i think that the prob occurs because from the same view I render another one form in the same template. This form is not multi-part. In this case it happens what I describe. If i put this simple form in comments (in views and in template) the multipart form uploads the file normally. Isn't it possible to handle these 2 forms in the same view?

 This is what I do:

def upload(request):

    c = {}

    c.update(csrf(request))

    if "vehicle-form" in request.POST:

        form = VForm(data=request.POST, own_id=u_id)

        print form.is_valid()

        if form.is_valid():

            form.save()

            return render_to_response('bingo.html', locals(), context_instance= RequestContext(request))

    else:

        form = VForm()

        

    if "doc-form" in request.POST: 

        form = LicenceForm(data=request.POST, files=request.FILES)

        if form.is_valid():

            handle_uploaded_file(request.FILES["docpath"])

            form.save()

            return render_to_response('success.html', locals(), context_instance=RequestContext(request))

    else:
