44 - created: When the user was created
45 - plugin_data: a mapping of extra plugin information for this User.

48 - pw_hash: Hashed version of user's password.
49 - email_verified: Whether or not the user has verified their email or not.
50 Most parts of the site are disabled for users who haven't yet.
51 - status: whether or not the user is active, etc. Currently only has two
52 values, 'needs_email_verification' or 'active'. (In the future, maybe
53 we'll change this to a boolean with a key of 'active' and have a
54 separate field for a reason the user's been disabled if that's
55 appropriate... email_verified is already separate, after all.)
56 - verification_key: If the user is awaiting email verification, the user
57 will have to provide this key (which will be encoded in the presented
58 URL) in order to confirm their email as active.
59 - is_admin: Whether or not this user is an administrator or not.
60 - url: this user's personal webpage/website, if appropriate.
61 - bio: biography of this user (plaintext, in markdown)
62 - bio_html: biography of the user converted to proper HTML.

):
95 Record of a piece of media.
98 - uploader: A reference to a User who uploaded this.
100 - title: Title of this work
102 - slug: A normalized "slug" which can be used as part of a URL to retrieve
103 this work, such as 'my-works-name-in-slug-form' may be viewable by
104 'http://mg.example.org/u/username/m/my-works-name-in-slug-form/'
105 Note that since URLs are constructed this way, slugs must be unique
106 per-uploader. (An index is provided to enforce that but code should be
107 written on the python side to ensure this as well.)
109 - created: Date and time of when this piece of work was uploaded.
111 - description: Uploader-set description of this work. This can be marked
112 up with MarkDown for slight fanciness (links, boldness, italics,
115 - description_html: Rendered version of the description, run through
116 Markdown and cleaned with our cleaning tool.
118 - media_type: What type of media is this? Currently we only support
121 - media_data: Extra information that's media-format-dependent.
122 For example, images might contain some EXIF data that's not appropriate
123 to other formats. You might store it like:
125 mediaentry.media_data['exif'] = {
126 'manufacturer': 'CASIO',
128 'exposure_time': .659}
130 Alternately for video you might store:
132 # play length in seconds
133 mediaentry.media_data['play_length'] = 340
135 ... so what's appropriate here really depends on the media type.
137 - plugin_data: a mapping of extra plugin information for this User.
138 Nothing uses this yet as we don't have plugins, but someday we
141 - tags: A list of tags. Each tag is stored as a dictionary that has a key
142 for the actual name and the normalized name-as-slug, so ultimately this
144 [{'name': 'Gully Gardens',
145 'slug': 'gully-gardens'},
146 {'name': 'Castle Adventure Time?!",
147 'slug': 'castle-adventure-time'}]
149 - state: What's the state of this file? Active, inactive, disabled, etc...
150 But really for now there are only two states:
151 "unprocessed": uploaded but needs to go through processing for display
152 "processed": processed and able to be displayed
154 - queued_media_file: storage interface style filepath describing a file
155 queued for processing. This is stored in the mg_globals.queue_store
158 - queued_task_id: celery task id. Use this to fetch the task state.
160 - media_files: Files relevant to this that have actually been processed
161 and are available for various types of display. Stored like:
162 {'thumb': ['dir1', 'dir2', 'pic.png'}
164 - attachment_files: A list of "attachment" files, ones that aren't
165 critical to this piece of media but may be usefully relevant to people
166 viewing the work. (currently unused.)
