Hy there, my first question on this website, so sorry for my english. So i try to upload a file on a model in Django framework.

class banner(models.Model):
#id is made by Django
name = models.CharField(max_length=255)
created_by = models.CharField(max_length=255)
company = models.CharField(max_length=255)
register_date = models.DateField(auto_now_add=True)
file = models.FileField(null=True, blank=True)
file_name = models.CharField(max_length=255)

this is the model

class BannerForm(forms.Form):
name=forms.CharField(max_length=255)
created_by=forms.CharField(max_length=255)
company=forms.CharField(max_length=255)
data_type=forms.CharField(max_length=255)
register_date=forms.DateField()
file=forms.FileField()
file_name=forms.CharField(max_length=255)

this is the form

def add_form(request): form=BannerForm() last=models.banner.objects.all().last()

if request.method == "POST":
    form = forms.BannerForm(request.POST, request.FILES or None)
    if form.is_valid():
        form.cleaned_data['created_by']
        new_banner=models.banner()
        new_banner.id=last.id+1
        new_banner.name=form.cleaned_data['name']
        new_banner.register_date=form.cleaned_data['register_date']
        new_banner.company=form.cleaned_data['company']
        new_banner.file=form.cleaned_data['file']
        new_banner.file_name=new_banner.file.name
        new_banner.created_by=form.cleaned_data['created_by']
        new_banner.save()

return render(request, "add_banner.html",{"form":form})

this is the view.Now every time i try to add a banner.I browse the file, but after i push submit, it is that the file must be chose, like it don't recongnize what i browse to the form button.Any suggestion?

well you need to specify the upload path in your models

file = models.FileField(null=True, blank=True,upload_to='files')

and make sure you have MEDIA_ROOT and MEDIA_URL defined in your settings.py

in your form

<form method="post" action="" enctype="multipart/form-data">
    {% csrf_token %}
    ...
</form>

How to upload a file in Django?, In this video you are going to learn the fundamentals about how to upload files with Django Duration: 17:12 Posted: Nov 12, 2018 Django comes with two form fields to upload files to the server, FileField and ImageField, the following is an example of using these two fields in our form forms.py: from django import forms class UploadDocumentForm(forms.Form): file = forms.FileField() image = forms.ImageField()

Try this something like this :

Models.py :

class banner(models.Model):
#id is made by Django
name = models.CharField(max_length=255)
created_by = models.CharField(max_length=255)
company = models.CharField(max_length=255)
register_date = models.DateField(auto_now_add=True)
file = models.FileField(upload_to='files/', null=True, blank=True)
file_name = models.CharField(max_length=255)

forms.py :

class BannerForm(forms.ModelForm):
    class Meta:
        model = banner #Or Banner ??
        fields = ('name', 'created_by', 'company', 'file', 'file_name' )

views.py :

from myapp.forms import BannerForm

if request.method == "POST":
    form = BannerForm(request.POST, request.FILES)
    if form.is_valid():
        entry = form.save(commit=False)
        entry.name = request.POST['name']
        entry.created_by = request.POST['created_by']
        entry.company = request.POST['company']
        entry.file_name = request.POST['file_name']
        form.save()

    else:
      form = BannerForm()

return render(request, "add_banner.html",locals())

And like already said, don't forget :

<form method="POST" action="" enctype="multipart/form-data">
    {% csrf_token %}
    {{form.name}}
    {{form.created_by}}
    {{form.company}}
    {{form.file_name}}
    {{form.file}}
    <input type="submit">
</form>

You don't have to specify these things :

new_banner.file=form.cleaned_data['file']

new_banner.register_date=form.cleaned_data['register_date'] -> useless because in your model you set auto_now_add=True, so you don't need te make a field in your HTML form.

Note : if your field created_by = models.CharField(max_length=255) is to put an existing user, so you should make a foreign key field like :

from django.contrib.auth.models import User
created_by = models.ForeignKey(User, verbose_name="Created by")

Comments
  • I forgot to mention: it says The submitted file is empty.
  • Do you have the enctype set in your form?
  • I have the enctype only in the add_banner.html template enctype="multipart/form-data"
  • STATIC_ROOT=os.path.join(os.path.dirname(BASE_DIR), "static_cdn") MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "media_cdn) I have those and i modify but still nothing the same thing
  • try the edited ans, and after adding the upload path to model, dont forget to make migrations and migrate
  • I was trying to upload an empty file, my dumb mistake, but question, when i try to upload the same file to a table where i have already have a row with that file it will overwritten?
  • if you are editing then it will overrite the old one, but the file will stay in the media folder
  • k, so sorry for bothering all of you with my lack of knowledge, it is the first time when i work with django. So now they store all my uploads in the main file of the project. Should i change file=models.FileField(null=True, blank=True, upload_to='files') to file=models.FileField(null=True, blank=True, upload_to='files/Media') if i wan the files to be fount the folder called Media?
  • <form action="" method= "POST", enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <input type="submit" class="button", value="Insert"> </form>

  • You can try. Django will automatically create a folder if it doesn't exists.
  • For example you can try also : upload_to='media/banner/whatever/'')
  • And the media folder will be created in the Project folder?
  • I think yes. On the root of your project folder, you will find a new folder called media or whatever you called it.
