django-upthor
=============

``django-upthor`` provides a django application for simple ajax file
uploads. We use https://github.com/blueimp/jQuery-File-Upload for the
upload functionality.

**Warning:** This isn't close to being a complete app, but it's getting
there.

Usage
=====

Step 1. Install
---------------

-  ``pip install django-upthor``

Now you have two options:

-  If you want to encrypt FQ values, install pycrypto.
   ``pip install pycrypto==2.6.1``
-  Or you can, disable FQ encryption by adding
   ``THOR_DISABLE_FQ_ENCRYPT = True`` to your settings file.

Step 2. (Django 1.6+)
---------------------

Add 'upthor' to your installed apps in settings.py:

::

    INSTALLED_APPS = (
        ...
        "upthor",
    )

Then:

::

    python manage.py migrate

Step 3. Use it in your app's models.
------------------------------------

::


    import os
    import uuid

    from django.db import models
    from upthor import fields as thor_fields


    def random_upload_path(instance, filename):
        # Split the uuid into two parts so that we won't run into subdirectory count limits. First part has 3 hex chars,
        #  thus 4k possible values.
        uuid_hex = uuid.uuid4().hex
        return os.path.join(uuid_hex[:3], uuid_hex[3:], filename)


    def post_example_file_link(real_instance, temporary_instance, raw_file):
        """
            A callback called after linking the temporary file with the model.

            **Warning**: Don't call instances save method from here, cause it will cause an recursion error.

            @:param real_instance An instance of the model the file is attached to
            @:param temporary_instance An instance of TemporaryFileWrapper that the form links to.
            @:param raw_file The raw file that is being uploaded.

            @:return bool If True, the uploaded temporary file is removed once the linking is complete.
        """
        return True


    def get_file_image(file_path):
        """ An optional function that returns the display image html for files after uploading is complete"""

        return '<i class="fa fa-file"></i>'


    class ExampleModelWithFile(models.Model):
        name = models.CharField(max_length=50)
        file = thor_fields.ThorFileField(upload_to=random_upload_path,
                                       allowed_types=['*'], widget=thor_fields.ThorSingleUploadWidget,
                                       post_link=post_product_file_link,
                                       get_upload_image=get_file_image)

Step 4. Make sure to include form media.
----------------------------------------

Make sure you include the media files for the form in your templates:

E.g. Add the following codes where form is the context object of your
modelform that uses the uploader fields.

::

        {{ form.media.css }}

        {{ form.media.js }}

Step 5. Add the upload url to your project urls.
------------------------------------------------

::

        url(r'', include('upthor.urls')),

Step 6. Optional stuff
----------------------

Temporary file cleanup
^^^^^^^^^^^^^^^^^^^^^^

If you want to clean up temporary files automatically, you'll need to
install `django-cron <https://github.com/Tivix/django-cron>`__ and add
``upthor.cron.CleanTemporaryFiles`` to your cron classes in settings.

Alternatively to clean up manually you can use the management command
``clean_temporary_files``.

Custom upload widget template
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You can override ``ThorSingleUploadWidget.render_template`` to return
your own widget template instead of the `hardcoded one defined in
widgets.py <upthor/widgets.py>`__. Although the structure (including
most classes) has to remain the same, there are a few data attributes on
``.file-upload`` that you can use to customize behavior:

+----------------------+----------+-------------------------------------------+
| Data Attribute Name  | Type     | Description                               |
+======================+==========+===========================================+
| upload-url           | string   | **Required:** URL to POST temporary files |
|                      |          | to, defaults to reverse of                |
|                      |          | ``thor-file-upload``.                     |
+----------------------+----------+-------------------------------------------+
| max-size             | number   | **Required:** Maximum allowed file size   |
|                      |          | in bytes, defaults to                     |
|                      |          | ``THOR_MAX_FILE_SIZE``.                   |
+----------------------+----------+-------------------------------------------+
| size-error           | string   | **Required:** Text to display if the file |
|                      |          | doesn't meet the size requirements,       |
|                      |          | defaults to                               |
|                      |          | ``"Uploaded file too large"``.            |
+----------------------+----------+-------------------------------------------+
| use-background       | boolean  | Whether or not to use                     |
|                      |          | ``background-image`` instead of ``img``   |
|                      |          | elements, defaults to false.              |
+----------------------+----------+-------------------------------------------+

Backends

Currently it only supports local file backend, but we plan to add other
backends when we reach a stable state.

Settings
========

The following settings are customizable using your django project
settings file.

**THOR\_UPLOAD\_TO**

Path where the upload files will be stored. Defaults to "temp-files".

**THOR\_EXPIRE\_TIME**

How long to keep temporary files in the database and on disk. Defaults
to "60*60*\ 24", e.g. 24 hours.

**THOR\_LINKED\_EXPIRE\_TIME**

How long to keep linked temporary files in the database and on disk.
Defaults to "60*60*\ 6", e.g. 6 hours.

**THOR\_MAX\_FILE\_SIZE**

The max file size of uploaded files. Defaults to "2*1024*\ 1024", e.g. 2
MB.

**THOR\_DISABLE\_FQ\_ENCRYPT**

Disable the FQ Encryption, if this is False you need to install pycrypto
since that is used for encryption. Defaults to "False".

**THOR\_ENABLE\_ADMIN**
