Etiquette
|
|
=========
|
|
|
|
I am currently running a demonstration copy of Etiquette at http://etiquette.voussoir.net where you can browse around. This is not yet permanent.
|
|
|
|
### What am I looking at
|
|
|
|
Etiquette is a tag-based file organization system with a web front-end.
|
|
|
|
Documentation is still a work in progress. In general,
|
|
|
|
- You must make the `etiquette` package importable by placing it in one of your lib paths because I have not made a setup.py yet. The easiest way to find your lib path is `python -c "import os; print(os)"`. Rather than actually moving the folder I just use filesystem junctions.
|
|
|
|
Windows: `mklink /J fakepath realpath`
|
|
for example `mklink /J "C:\Python36\Lib\etiquette" "D:\Git\Etiquette\etiquette"`
|
|
|
|
Linux: `ln --symbolic realpath fakepath`
|
|
for example `ln --symbolic "/home/Owner/Git/Etiquette/etiquette" "/usr/local/lib/python3.6/etiquette"`
|
|
|
|
I'm sure you'll figure it out.
|
|
|
|
- Run `python etiquette_flask_launch.py [port]` to launch the flask server. Port defaults to 5000 if not provided.
|
|
- Run `python -i etiquette_repl_launch.py` to launch the Python interpreter with the PhotoDB pre-loaded into a variable called `P`. Try things like `P.new_photo` or `P.digest_directory`.
|
|
- Note: Do not `cd` into the frontends folder. Stay wherever you want the photodb to be created, and start the frontend by specifying full file path of the launch file.
|
|
|
|
### Project stability
|
|
|
|
You may notice that Etiquette doesn't have a version number anywhere. That's because I don't think it's ready for one. I am using this project to learn and practice, and breaking changes are very common.
|
|
|
|
### Project structure
|
|
|
|
Here is a brief overview of the project to help you learn your way around:
|
|
|
|
- `etiquette`
|
|
The core backend package.
|
|
- `objects`
|
|
Definition of the Etiquette data objects like Photos and Tags.
|
|
- `photodb`
|
|
Definition of the PhotoDB class and its Mixins.
|
|
- `frontends`
|
|
Ideally, the backend should be frontend-agnostic. Even though the Flask interface is my primary interest, it should not feel like it must be the only one. Therefore I place it in this folder to indicate that other frontends are possible too. Every folder here is essentially a completely separate project.
|
|
- `etiquette_flask`
|
|
This folder represents the flask server as somewhat of a black box, in the sense that you can move it around and just run the contained launch file. Subfolders contain the HTML templates, static files, and site code.
|
|
- `etiquette_flask`
|
|
The package that contains the site's actual API code.
|
|
- `etiquette_repl`
|
|
Preloads a few variables into the interpreter so you can quickly test functions within the Python REPL itself.
|
|
- `utilities`
|
|
For other scripts that will be used with etiquette databases, but are not part of the library itself.
|
|
|
|
### To do list
|
|
- Make the wording between "new", "create", "add"; and "remove", "delete" more consistent.
|
|
- User account system, permission levels, private pages.
|
|
- Improve the "tags on this page" list. Maybe add separate buttons for must/may/forbid on each.
|
|
- Some way for the database to re-identify a file that was moved / renamed (lost & found). Maybe file hash of the first few mb is good enough.
|
|
- Debate whether the `UserMixin.login` method should accept usernames or I should standardize the usage of IDs only internally.
|
|
- Ability to access user photos by user's ID, not just username.
|
|
- Should album size be cached on disk?
|
|
- Replace columns like area, ratio, bitrate by using expression indices or views (`width * height` etc).
|
|
- Add a `Photo.merge` to combine duplicate entries.
|
|
- Generate thumbnails for vector files without falling victim to bombs.
|
|
- Allow photos to have nonstandard, orderby-able properties like "release year". How?
|
|
- When users have '%' or '#', etc. in their username, it is difficult to access their /user/ URL. I would prefer to fix it without simply blacklisting those characters.
|
|
- Currently, the Jinja templates are having a tangling influence on the backend objects, because Jinja cannot import my other modules like bytestring, but it can access the methods of the objects I pass into the template. As a result, the objects have excess helper methods. Consider making them into Jinja filters instead. Which is also kind of ugly but will move that pollution out of the backend at least.
|
|
- Perhaps instead of actually deleting objects, they should just have a `deleted` flag, to make easy restoration possible. Also consider regrouping the children of restored Groupables if those children haven't already been reassigned somewhere else.
|
|
- Add a new table to store permanent history of add/remove of tags on photos, so that accidents or trolling can be reversed.
|
|
- Fix album size cache when photo reload metadata and generally improve that validation.
|
|
- Better bookmark url validation.
|
|
- Create a textbox which gives autocomplete tag names.
|
|
- Consider if the "did you commit too early" warning should actually be an exception.
|
|
- Extension currently does not believe in the override filename. On one hand this is kind of good because if they override the name to have no extension, we can still provide a downloadable file with the correct extension by remembering it. But on the other hand it does break the illusion of override_filename.
|
|
|
|
### To do list: User permissions
|
|
Here are some thoughts about the kinds of features that need to exist within the permission system. I don't know how I'll actually manage it just yet. Possibly a `permissions` table in the database with `user_id | permission` where `permission` is some reliably-formatted string.
|
|
|
|
- Preventing logged out users from viewing any page except root and /login.
|
|
- Uploading photos (`can_upload`)
|
|
- File extension restrictions
|
|
- Add / remove tags from photo
|
|
- My own photos (`can_tag_own`)
|
|
- Explicit individual allow / deny (`can_tag_photo:<photo_id>`)
|
|
- General allow / deny (`can_tag`)
|
|
- Deleting photos
|
|
- etc
|
|
- Creating albums
|
|
- As children of my own albums
|
|
- Add / remove photos from album, edit title / desc.
|
|
- My own albums (`can_edit_album_own`)
|
|
- Explicit (`can_edit_album:<album_id>`)
|
|
- General (`can_edit_album`)
|
|
- Deleting albums
|
|
- etc
|
|
- Creating tags (`can_create_tag`)
|
|
- Deleting tags (`can_delete_tag`)
|
|
- Only those that I have created (`can_delete_tag_own`)
|
|
- Any time vs. only if they are not in use (`can_delete_tag_in_use`)
|
