Many people ask and also has the need to verify that the file is sent to
the server is really in its place.
This need arises because they are made unnecessary requests for lack of
the file in media server and also for reasons of aesthetics, because the
lack of image files or result in a different box with alt attribute, or
result in a 404 not found.
The class FieldFile not give the developer the possibility to check if
file exists and that is the developers create a method in a class model
which will check if file exists on the media server or not.
I created a patch where it created a method for class FieldFile call
is_exists which checks if the file exists. This method is valid for all
inheritance of FieldFile class.
For example,
{{{
{% if object.file.is_exists %}<a href="{{ MEDIA_URL }}{{ object.file
}}">download this file</a>{% endif %}
{% if object.image.is_exists %}<img src="{{ MEDIA_URL }}{{ object.image
}}" alt="My image" />{% endif %}
}}}
