falocalrepo-server 3.0.1

Web interface for falocalrepo.

FALocalRepo-Server

Web interface for falocalrepo.

Installation & Requirements

To install the program it is sufficient to use Python pip and get the package falocalrepo-server.

pip install falocalrepo-server

Python 3.10 or above is needed to run this program, all other dependencies are handled by pip during installation. For information on how to install Python on your computer, refer to the official website Python.org.

For the program to run, a properly formatted database created by falocalrepo needs to be present in the same folder.

The styling is based on the Boostrap CSS framework.

Usage

falocalrepo-server <database> [--host HOST] [--port PORT] [--ssl-cert SSL_CERT] [--ssl-key SSL_KEY] 
                   [--redirect-http REDIRECT_PORT] [--auth <username>:<password>] [--precache]

The server needs one argument pointing at the location of a valid falocalrepo database and accepts optional arguments to manually set host, port, and an SSL certificate with key. By default, the server is run on 0.0.0.0:80 for HTTP (without certificate) and 0.0.0.0:443 for HTTPS (with certificate).

The --precache options can be used to prepare an initial cache of results from the database to speed up searches.

Redirect Mode

The optional --redirect-http argument changes the app mode to redirection. In this mode the app runs a tiny server that redirects all HTTP requests it receives on http://HOST:PORT to https://HOST:REDIRECT_PORT.

Note: In redirect mode the database argument is not checked, so a simple . is sufficient. Note: In redirect mode the app does not operate the database portion of the server. To run in redirect and server mode, two separate instances of the program are needed.

Once the server is running the web app can be accessed at the address shown in the terminal.

Authentication

The --auth option allows setting up a username and password to access the server using the HTTP Basic authentication protocol.

Arguments

Argument	Default
database	None, mandatory argument
--host	0.0.0.0
--port	80 if no SSL certificate is given, 443 otherwise
--ssl-cert	None
--ssl-key	None
--redirect-http	None
--auth	None
--precache	False

Examples

# Launch an HTTP server reachable from other machines using the server's hostname/IP
falocalrepo-server ~/FA.db

# Launch a localhost-only server on port 8080
falocalrepo-server ~/FA.db --host 127.0.0.1 --port 8080

# Launch a redirect server that listens to port 80 and redirects to port 443 on host 0.0.0.0
falocalrepo-server . --host 0.0.0.0 --port 80 --redirect-htpp 443

# Launch a server with basic authentication using 'mickey' as username and 'mouse' as password
falocalrepo-server ~/FA.db --auth mickey:mouse

# Launch an HTTPS server reachable from other machines using the server's hostname/IP
falocalrepo-server ~/FA.db --ssl-cert ~/FA.certificates/certificate.crt --ssl-key ~/FA.certificates/private.key 

# Launch a localhost-only HTTPS server on port 8443
falocalrepo-server ~/FA.db --host 127.0.0.1 --port 8443 --ssl-cert ~/FA.certificates/certificate.crt --ssl-key ~/FA.certificates/private.key

Pages

Home

The home page displays general information about the database and contains links to browse and search pages for the various tables.

The information table displays the total number of submissions, journals, and users together with the version of the database. Clicking on any of the counters open the relevant search & browse page.

Browse & Search

The browse and search pages allow to explore the submissions/journals contained in the database. Searches are performed case-insensitively using a simple syntax in the form @field term [[| &] term ...] which allows logic operators, parentheses and start/end of field matching, see Query Language for details.

Search terms for submissions and journals default to the any field if none is used, while the username field is used for users searches.

The controls at the top of the page allow to query the database and control the visualisation of the results.

The Search input allows to insert the search query.

The Field menu allows to insert a specific search field using a simple dropdown menu.

The Sort and adjacent order menus change the sorting field and order of the search results. Submissions and journals default to descending ID, while users default to ascending username.

The View menu allows changing between the (default) grid view to a list (table) view

The Search button submits the search request using the current query and sorting settings.

The Browse button resets the current search query and reverts to browse mode (all entries).

The FA button opens the current search on Fur Affinity, translating the shared search and sorting fields (tags, author, description, and fileurl/fileext). The button is only available when searching submissions.

The gear button opens the search settings, the question mark button shows a quick help about the query language.

Under the search controls are the number of results and current page.

Under the results numbers are the page controls. First leads to page 1, Prev leads to the previous page, Next leads to the next page, and Last leads to the last page. These controls are also available at the bottom of the page.

In grid view, the results are presented using cards containing the same information as the list view, with the addition of thumbnails for submissions. When searching for submissions or journals, clicking on the card footer (containing the date and author) will open the author's page.

In list view, the results are presented in a table with the most important columns: ID, AUTHOR, DATE, and TITLE ( submissions and journals); USERNAME, FOLDERS, and ACTIVE (users). On small screens some of these columns are shortened or removed.

Compatibility with Fur Affinity Search

Most Fur Affinity search queries (and links) are fully compatible with the program.

Except for the NOT (!) operator, which follows different syntax rules, all Fur Affinity search fields are fully supported: @lower (treated as @author), @keywords (treated as @tags), @message (treated as @description) , @title (treated as @title), @filename (treated as @fileurl).

Query Language

The query language used for this server is based on and improves the search syntax currently used by the Fur Affinity website. Its basic elements are:

• @<field> field specifier (e.g. @title), all database columns are available as search fields. See falocalrepo-database for details on the available columns.
• () parentheses, they can be used for better logic operations
• & AND logic operator, used between search terms
• | OR logic operator, used between search terms
• ! NOT logic operator, used as prefix of search terms
• "" quotes, allow searching for literal strings without needing to escape
• % match 0 or more characters
• _ match exactly 1 character
• ^ start of field, when used at the start of a search term, it matches the beginning of the field
• $ end of field, when used at the end of a search term, it matches the end of the field

All other strings are considered search terms.

The search uses the @any field by default, allowing to do general searches without specifying a field.

Search terms that are not separated by a logic operator are considered AND terms (i.e. a b c -> a & b & c).

Except for the ID, AUTHOR, FILESAVED, USERUPDATE, USERNAME, and ACTIVE fields, all search terms are searched through the whole content of the various fields: i.e. @description cat will match any item whose description field contains "cat". To match items that contain only "cat" (or start with, end with, etc.), the %, _, ^, and $ operators need to be used (e.g. @description ^cat).

Search terms for ID, AUTHOR, and USERNAME are matched exactly as they are: i.e. @author tom will match only items whose author field is exactly equal to "tom", to match items that contain "tom" the %, _, ^, and $ operators need to be used (e.g. @author %tom%).

Examples

Search for journals/submissions containing water and either otter, lutrine, or mustelid, or water and either cat or feline:

water ((otter | lutrine | mustelid) | (cat | feline))

@any water & ((otter | lutrine | mustelid) | (cat | feline))

Search for journals/submissions containing "cat" or "feline" but neither "mouse" nor "rodent":

(cat | feline) !mouse !rodent

Search for general-rated submissions uploaded by a user whose name starts with "tom" that contain either "volleyball" or "volley" and "ball" separated by one character (e.g. "volley-ball") in any field:

@rating general @author tom% @any (volleyball | volley_ball)

(volleyball | volley_ball) @rating general @author tom%

Search for journals/submissions uploaded in 2020 except for March:

@date ^2020 !^2020-03

Search for submissions uploaded in March 2021 (meaning the date has to start with 2021-03) whose tags contain the exact tag "ball":

@date ^2021-03 @tags "|ball|"

@date ^2021-03 @tags \|ball\|

Search for journals/submissions where a specific user named "tom" is mentioned:

@mentions "|tom|"

@mentions \|tom\|

Search for submissions whose only favorite is a user named "alex":

@favorite ^\|alex\|$

Search for users whose names contain "mark":

@username %mark%

Search for journals/submissions whose title ends with "100%":

@title 100\%$

Search for journals/submissions whose title is exactly "cat":

@title ^cat$

Search for text submissions with PDF files:

@type text @fileext pdf

Search Settings

The search settings page allows modifying the sorting, ordering, and viewing option that are applied by default to the various searches. Settings can be saved to the database if it is writable, otherwise they are simply saved for the current session and reset when the program stops.

Settings values are saved in the SETTINGS table with the SERVER.SEARCH setting name.

User

The user page shows information about submissions and journals related to a user (gallery, scraps, favorites, mentions, and journals) and what folders have been set for download. See falocalrepo for more details on this. The user's profile will be displayed if present in the database.

Clicking on any of the counters opens the relevant results via the search interface, allowing to refine the search further.

The Next and Prev buttons move to the respective users in ascending alphabetical order.

Submission

The submission page shows the submission file (if present), the submission metadata, and the description.

Image, audio, and plain text submission files are displayed directly in the page, others (e.g. PDF files) will display a link to open them. For images, clicking on the images opens its file.

The metadata table contains clickable links to the user's page (see User for details), tags, category, species, gender, rating, folder (gallery/scraps), and to user pages of favouring and mentioned users.

The description is displayed as-is except for user icons, which are replaced by @username styled links to avoid display errors caused by expired icon links.

Under the metadata table are a number of buttons that allow to access the submission file, open its Fur Affinity counterpart, and navigate the other submissions from the author.

The download File button downloads the submission file (if present).

The download ZIP button generates a ZIP file containing the submission file, submission thumbnail, description HTML, and metadata in JSON format.

The FA button opens the submission on Fur Affinity

The Next and Prev buttons lead to the next more recent and the previous less recent submissions respectively.

The Gallery, All, and Scraps buttons open a search page with the user's gallery submissions, scraps and gallery submissions together, and scraps submissions respectively.

Journal

The journal page shows the journal metadata and content.

The metadata table contains clickable links to the user's page (see User for details) and to user pages of mentioned users.

Under the metadata table are a number of buttons that allow to download the journal, open its Fur Affinity counterpart, and navigate the other journals from the same user.

The download ZIP button generates a ZIP file containing the journal content HTML and metadata in JSON format.

The FA button opens the journal on Fur Affinity

The Next and Prev buttons lead to the next more recent, and the previous less recent journals respectively.

The All button opens a search page with all the user's journals.
