# Unggah Berkas

When Django handles a file upload, the file data ends up placed in
[`request.FILES`](/id/6.0/ref/request-response/#django.http.HttpRequest.FILES) (for more on the
`request` object see the documentation for [request and response objects](/id/6.0/ref/request-response/)). This document explains how files are stored on disk
and in memory, and how to customize the default behavior.

## Unggah berkas dasar

Pertimbangkan sebuah formulir mengandung [`FileField`](/id/6.0/ref/forms/fields/#django.forms.FileField):

*`forms.py`*

```python
from django import forms

class UploadFileForm(forms.Form):
    title = forms.CharField(max_length=50)
    file = forms.FileField()
```

A view handling this form will receive the file data in
[`request.FILES`](/id/6.0/ref/request-response/#django.http.HttpRequest.FILES), which is a dictionary
containing a key for each [`FileField`](/id/6.0/ref/forms/fields/#django.forms.FileField) (or
[`ImageField`](/id/6.0/ref/forms/fields/#django.forms.ImageField), or other [`FileField`](/id/6.0/ref/forms/fields/#django.forms.FileField)
subclass) in the form. So the data from the above form would
be accessible as `request.FILES['file']`.

Note that [`request.FILES`](/id/6.0/ref/request-response/#django.http.HttpRequest.FILES) will only
contain data if the request method was `POST`, at least one file field was
actually posted, and the `<form>` that posted the request has the attribute
`enctype="multipart/form-data"`. Otherwise, `request.FILES` will be empty.

Most of the time, you'll pass the file data from `request` into the form as
described in [Mengikat berkas terunggah ke formulir](/id/6.0/ref/forms/api/#binding-uploaded-files). This would look something like:

*`views.py`*

```python
from django.http import HttpResponseRedirect
from django.shortcuts import render
from .forms import UploadFileForm

# Imaginary function to handle an uploaded file.
from somewhere import handle_uploaded_file

def upload_file(request):
    if request.method == "POST":
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            handle_uploaded_file(request.FILES["file"])
            return HttpResponseRedirect("/success/url/")
    else:
        form = UploadFileForm()
    return render(request, "upload.html", {"form": form})
```

Melihat bahwa kita harus melewatkan [`request.FILES`](/id/6.0/ref/request-response/#django.http.HttpRequest.FILES) kedalam pembangun formulir; ini adalah bagaimana data berkas dapat mengikat kedalam formulir.

Ini adalah cara umum anda mungkin menangani sebuah berkas terunggah:

```
def handle_uploaded_file(f):
    with open("some/file/name.txt", "wb+") as destination:
        for chunk in f.chunks():
            destination.write(chunk)
```

Looping over `UploadedFile.chunks()` instead of using `read()` ensures that
large files don't overwhelm your system's memory.

There are a few other methods and attributes available on `UploadedFile`
objects; see [`UploadedFile`](/id/6.0/ref/files/uploads/#django.core.files.uploadedfile.UploadedFile) for a complete reference.

### Penanganan berkas terunggah dengan model

Jika anda sedang menyimpan sebuah berkas pada [`Model`](/id/6.0/ref/models/instances/#django.db.models.Model) dengan [`FileField`](/id/6.0/ref/models/fields/#django.db.models.FileField), menggunakan [`ModelForm`](/id/6.0/topics/forms/modelforms/#django.forms.ModelForm) memuat pengolahan ini lebih mudah. byek berkas akan disimpan ke tempat ditentukan oleh argumen [`upload_to`](/id/6.0/ref/models/fields/#django.db.models.FileField.upload_to) dari [`FileField`](/id/6.0/ref/models/fields/#django.db.models.FileField)  sesuai ketika memanggil `form.save()`:

```
from django.http import HttpResponseRedirect
from django.shortcuts import render
from .forms import ModelFormWithFileField

def upload_file(request):
    if request.method == "POST":
        form = ModelFormWithFileField(request.POST, request.FILES)
        if form.is_valid():
            # file is saved
            form.save()
            return HttpResponseRedirect("/success/url/")
    else:
        form = ModelFormWithFileField()
    return render(request, "upload.html", {"form": form})
```

If you are constructing an object manually, you can assign the file object from
[`request.FILES`](/id/6.0/ref/request-response/#django.http.HttpRequest.FILES) to the file field in the
model:

```
from django.http import HttpResponseRedirect
from django.shortcuts import render
from .forms import UploadFileForm
from .models import ModelWithFileField

def upload_file(request):
    if request.method == "POST":
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            instance = ModelWithFileField(file_field=request.FILES["file"])
            instance.save()
            return HttpResponseRedirect("/success/url/")
    else:
        form = UploadFileForm()
    return render(request, "upload.html", {"form": form})
```

If you are constructing an object manually outside of a request, you can assign
a [`File`](/id/6.0/ref/files/file/#django.core.files.File) like object to the
[`FileField`](/id/6.0/ref/models/fields/#django.db.models.FileField):

```
from django.core.management.base import BaseCommand
from django.core.files.base import ContentFile

class MyCommand(BaseCommand):
    def handle(self, *args, **options):
        content_file = ContentFile(b"Hello world!", name="hello-world.txt")
        instance = ModelWithFileField(file_field=content_file)
        instance.save()
```

### Mengunggah banyak berkas

If you want to upload multiple files using one form field, create a subclass
of the field's widget and set its `allow_multiple_selected` class attribute
to `True`.

In order for such files to be all validated by your form (and have the value of
the field include them all), you will also have to subclass `FileField`. See
below for an example.

> **Multiple file field**
>
> Django is likely to have a proper multiple file field support at some point
> in the future.

*`forms.py`*

```python
from django import forms

class MultipleFileInput(forms.ClearableFileInput):
    allow_multiple_selected = True

class MultipleFileField(forms.FileField):
    def __init__(self, *args, **kwargs):
        kwargs.setdefault("widget", MultipleFileInput())
        super().__init__(*args, **kwargs)

    def clean(self, data, initial=None):
        single_file_clean = super().clean
        if isinstance(data, (list, tuple)):
            result = [single_file_clean(d, initial) for d in data]
        else:
            result = [single_file_clean(data, initial)]
        return result

class FileFieldForm(forms.Form):
    file_field = MultipleFileField()
```

Then override the `form_valid()` method of your
[`FormView`](/id/6.0/ref/class-based-views/generic-editing/#django.views.generic.edit.FormView) subclass to handle multiple file
uploads:

*`views.py`*

```python
from django.views.generic.edit import FormView
from .forms import FileFieldForm

class FileFieldFormView(FormView):
    form_class = FileFieldForm
    template_name = "upload.html"  # Replace with your template.
    success_url = "..."  # Replace with your URL or reverse().

    def form_valid(self, form):
        files = form.cleaned_data["file_field"]
        for f in files:
            ...  # Do something with each file.
        return super().form_valid(form)
```

> **Warning**
>
> This will allow you to handle multiple files at the form level only. Be
> aware that you cannot use it to put multiple files on a single model
> instance (in a single field), for example, even if the custom widget is used
> with a form field related to a model `FileField`.

## Penanganan Unggah

When a user uploads a file, Django passes off the file data to an *upload
handler* -- a small class that handles file data as it gets uploaded. Upload
handlers are initially defined in the [`FILE_UPLOAD_HANDLERS`](/id/6.0/ref/settings/#std-setting-FILE_UPLOAD_HANDLERS) setting,
which defaults to:

```
[
    "django.core.files.uploadhandler.MemoryFileUploadHandler",
    "django.core.files.uploadhandler.TemporaryFileUploadHandler",
]
```

Together [`MemoryFileUploadHandler`](/id/6.0/ref/files/uploads/#django.core.files.uploadhandler.MemoryFileUploadHandler) and
[`TemporaryFileUploadHandler`](/id/6.0/ref/files/uploads/#django.core.files.uploadhandler.TemporaryFileUploadHandler) provide Django's default file upload
behavior of reading small files into memory and large ones onto disk.

You can write custom handlers that customize how Django handles files. You
could, for example, use custom handlers to enforce user-level quotas, compress
data on the fly, render progress bars, and even send data to another storage
location directly without storing it locally. See [Menulis penangan unggah penyesuaian](/id/6.0/ref/files/uploads/#custom-upload-handlers)
for details on how you can customize or completely replace upload behavior.

### Dimana data terunggah disimpan

Sebelum anda menyimpan berkas terunggah, data butuh disimpan di suatu tempat.

By default, if an uploaded file is smaller than 2.5 megabytes, Django will hold
the entire contents of the upload in memory. This means that saving the file
involves only a read from memory and a write to disk and thus is very fast.

Bagaimanapun, jika sebuah berkas terunggah terlalu besar, Django akan menulis berkas terunggah ke berkas sementara disimpan di sistem direktori sementara. Pada serambi seperti-Unix ini berarti anda dapat mengharap Django membangkitkan sebuah berkas dipanggil seperti sesuatu `/tmp/tmpzfp6I6.upload`. Jika sebuah unggahan cukup besar, anda dapat melihat berkas ini tumbuh dalam ukuran seperti Django mengalirkan data ke cakram.

These specifics -- 2.5 megabytes; `/tmp`; etc. -- are "reasonable defaults"
which can be customized as described in the next section.

### Merubah perilaku penanganan unggah

Ada sedikit pengaturan yang mengendalikan perilaku unggah berkas Django. Lihat File Upload Settings 1 untuk rincian.

### Merubah penanganan unggah dengan cepat

Sometimes particular views require different upload behavior. In these cases,
you can override upload handlers on a per-request basis by modifying
`request.upload_handlers`. By default, this list will contain the upload
handlers given by [`FILE_UPLOAD_HANDLERS`](/id/6.0/ref/settings/#std-setting-FILE_UPLOAD_HANDLERS), but you can modify the list
as you would any other list.

For instance, suppose you've written a `ProgressBarUploadHandler` that
provides feedback on upload progress to some sort of AJAX widget. You'd add
this handler to your upload handlers like this:

```
request.upload_handlers.insert(0, ProgressBarUploadHandler(request))
```

Using `list.insert()`, as shown above, ensures that the progress bar handler
is placed at the beginning of the list. Since upload handlers are executed in
order, this placement guarantees that the progress bar handler runs before the
default handlers, allowing it to track progress across the entire upload.

If you want to replace the upload handlers completely, you can assign a new
list:

```
request.upload_handlers = [ProgressBarUploadHandler(request)]
```

> **Note**
>
> You can only modify upload handlers *before* accessing
> `request.POST` or `request.FILES` -- it doesn't make sense to
> change upload handlers after upload handling has already
> started. If you try to modify `request.upload_handlers` after
