Tutorial: Adding Camera information to galleries¶

Prerequisites¶

Here we’ll assume you have a working Tutorial: Quickstart setup.

Goals¶

We’ll add camera information extracted from EXIF parsing to database, and in our photo gallery.

Updating settings¶

`settings.py`¶

Add the following in INSTALLED_APPS:

"mg.metadata.camera_info",

Update the database:

user@host quickstart $ ./manage.py syncdb

Updating the templates¶

In templates/element/element_detail.html, add the following:

In header, add a “load” block:
```
{% load mg_camera_info %}
```
In block content, add the following tag:
```
{% camera_info object %}
```

Code should look like:

{% extends "base.html" %}
{% load mg_element %}
{% load mg_camera_info %}

{% block title %}{{object.name}}{% endblock %}

{% block content %}
<p><a href="/">Back to list</a></p>
{% elem_view object %}
<dl>
 <dt>Name</dt>
 <dd>{{ object.name }}</dd>
 <dt>Timestamp</dt>
 <dd>{{ object.timestamp }}</dd>
</dl>
{% camera_info object %}
{% endblock %}

Updating photo metadata¶

If we had the application present at time of import, this would have been done transparently, but now we can update database afterwards:

user@host quickstart $ ./manage.py mg_update
Supported types: photo
MetaUpdater 4/10
 ExifOrientation Deleted data associated with IMG_1144
 ExifPhotoInfo  ExifCameraInfo Deleted data associated with IMG_1144
 CreateResizedPhoto . .  CreateThumbnail . .
MetaUpdater 5/10
 ExifOrientation Deleted data associated with IMG_1145
 ExifPhotoInfo  ExifCameraInfo Deleted data associated with IMG_1145
 CreateResizedPhoto . .  CreateThumbnail . .
MetaUpdater 6/10
 ExifOrientation Deleted data associated with IMG_1146
 ExifPhotoInfo  ExifCameraInfo Deleted data associated with IMG_1146
 CreateResizedPhoto . .  CreateThumbnail . .
user@host quickstart $

See Updating Metadata for more information.

We’re done !¶

That’s it, you successfully added Exif camera metadata support. You can see the result running the server:

user@host quickstart $ ./manage.py runserver

What’s next ?¶

You may want to:

add photo info support, this is exactly the same thing with The mg.metadata.photo_info application.
add some hierarchical models, to sort your media library your way, see Tutorial: Sorting galleries through rolls.
