Why this change?
Before this change, the validation error message shown to the user when
saving a theme objects setting is very cryptic. This commit changes the
validation error messages to be displayed on top of the editor instead.
Note that I don't think this way of displaying is the ideal state we
want to get to but given the time we have this will do for now.
Why this change?
In cdba864598, we added support for adding
a description which will be displayed under the input of each property
on the client side.
Currently this convention in the locale file is followed:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name: <description for the name property>
links:
name: <description for the name property in link>
url: <description for the url property in link>
```
Since we now want to allow the label to be translated as well, we will
be changing the convention to the following:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name:
label: <label for the name property>
description: <description for the name property>
links:
name:
label: <label for the name property>
description: <description for the name property in link>
url:
label: <label for the url property>
description: <description for the url property in link>
```
If the locale file does not provide a `label` key under the property's
name, the client side will just display the property's name as the
label for the input field.
Why this change?
This is a follow-up to 86b2e3aa3e.
Basically, we want to allow people to select more than 1 category as well.
What does this change do?
1. Change `type: category` to `type: categories` and support `min` and `max`
validations for `type: categories`.
2. Fix the `<SchemaThemeSetting::Types::Categories>` component to support the
`min` and `max` validations and switch it to use the `<CategorySelector>` component
instead of the `<CategoryChooser>` component which only supports selecting one category.
Why this change?
Previously, we were preloading the necessary metadata for
`adminCustomizeThemes.show.schema` route in the
`adminCustomizeThemes.show` route. This is wasteful because we're
loading data upfront when the objects setting editor may not be used.
This change also lays the ground work for a future commit where we need
to be shipping down additional metadata which may further add to the
payload.
Why this change?
On the `/admin/customize/themes/<:id>` route, we allow admins to edit
all settings via a settings editor. Prior to this change, trying to edit
and save a typed objects theme settings will result in an error on the
server.
Why this change?
Importing theme with the `bundle` params is used mainly by
`discourse_theme` CLI in the development environment. However, we do not
want migrations to automatically run in the development environment
and instead want the developer to be intentional about running theme
migrations. As such, this commit adds support for a
`skip_migrations` param when importing a theme with the `bundle` params.
This commit also adds a `migrated` attribute for migrations theme fields
to indicate whether a migrations theme field has been migrated or not.
The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
This commit introduces a new feature that allows theme developers to manage the transformation of theme settings over time. Similar to Rails migrations, the theme settings migration system enables developers to write and execute migrations for theme settings, ensuring a smooth transition when changes are required in the format or structure of setting values.
Example use cases for the theme settings migration system:
1. Renaming a theme setting.
2. Changing the data type of a theme setting (e.g., transforming a string setting containing comma-separated values into a proper list setting).
3. Altering the format of data stored in a theme setting.
All of these use cases and more are now possible while preserving theme setting values for sites that have already modified their theme settings.
Usage:
1. Create a top-level directory called `migrations` in your theme/component, and then within the `migrations` directory create another directory called `settings`.
2. Inside the `migrations/settings` directory, create a JavaScript file using the format `XXXX-some-name.js`, where `XXXX` is a unique 4-digit number, and `some-name` is a descriptor of your choice that describes the migration.
3. Within the JavaScript file, define and export (as the default) a function called `migrate`. This function will receive a `Map` object and must also return a `Map` object (it's acceptable to return the same `Map` object that the function received).
4. The `Map` object received by the `migrate` function will include settings that have been overridden or changed by site administrators. Settings that have never been changed from the default will not be included.
5. The keys and values contained in the `Map` object that the `migrate` function returns will replace all the currently changed settings of the theme.
6. Migrations are executed in numerical order based on the XXXX segment in the migration filenames. For instance, `0001-some-migration.js` will be executed before `0002-another-migration.js`.
Here's a complete example migration script that renames a setting from `setting_with_old_name` to `setting_with_new_name`:
```js
// File name: 0001-rename-setting.js
export default function migrate(settings) {
if (settings.has("setting_with_old_name")) {
settings.set("setting_with_new_name", settings.get("setting_with_old_name"));
}
return settings;
}
```
Internal topic: t/109980
Why this change?
Currently, we do not have an easy way to test themes and theme components
using Rails system tests. While we support QUnit acceptance tests for
themes and theme components, QUnit acceptance tests stubs out the server
and setting up the fixtures for server responses is difficult and can lead to a
frustrating experience. System tests on the other hand allow authors to
set up the test fixtures using our fabricator system which is much
easier to use.
What does this change do?
In order for us to allow authors to run system tests with their themes
installed, we are adding a `upload_theme` helper that is made available
when writing system tests. The `upload_theme` helper requires a single
`directory` parameter where `directory` is the directory of the theme
locally and returns a `Theme` record.
The value field of ThemeField is only used when viewing a diff in the staff action logs and local theme editing. value is being serialized into the theme index as well, which is not used. It's a huge amount of JSON that we can cut by removing it.
This also breaks up the various theme serializers into separate classes so they autoload properly (or at least restart the server on edit)
* DEV: Add a dedicated Admin::StaffController base controller
The current parent(Admin:AdminController) for all admin-related controllers
uses a filter that allows only staff(admin, moderator) users.
This refactor makes Admin::AdminController filter for only admins as the name suggests and
introduces a base controller dedicated for staff-related endpoints.
* DEV: Set staff-only controllers parent to Admin::StaffController
Refactor staff-only controllers to inherit newly introduced
Admin::StaffController abstract controller. This conveys the
purpose of the parent controller better unlike the previously used parent
controller.
* SECURITY: moderator shouldn't be able to import a theme via API.
* DEV: apply `AdminConstraint` for all the "themes" routes.

The generate RSA key and import theme routes worked separate from each
other. The RSA key returned both the public and private key and it was
the frontend which posted the private key back to the server. With this
commit, only the public key is necessary as the server keeps a map of
public and private keys that is used to get the private key back from
a public key.
A public key must be added to GitHub when installing private themes.
When the process happens asynchronously (for example if the admin does
not have admin permissions to the GitHub repository), installing
private themes becomes very difficult.
In this case, the Discourse admin can partially install the theme by
letting Discourse save the private key, create a placeholder theme and
give the admin a public key to be used as a deploy key. After the key
is installed, the admin can finish theme installation by pressing a
button on the theme page.
There are still some, but those are in actual code that's used outside core, so the change there would need to go through the deprecation cycle. That's a task for another day.
Previous to this change if any of the assets were not allowed extensions
they would simply be silently ignored, this could lead to broken themes
that are very hard to debug
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
aa1442fdc3 split theme stylesheets so that every component gets its own stylesheet. Therefore, there is now no need for parent themes to collate the settings/variables of its children during scss compilation.
Technically this is a breaking change for any themes which depend on the settings/variables of their child components. That was never a supported/recommended arrangement, so we don't expect this to cause issues.
Related to: 20f736aa11.
`auto_update` is true by default at the database level, but it doesn't make sense for `auto_update` to be true on themes that are not imported from a Git repository.
* FIX: allowed_theme_ids should not be persisted in GlobalSettings
It was observed that the memoized value of `GlobalSetting.allowed_theme_ids` would be persisted across requests, which could lead to unpredictable/undesired behaviours in a multisite environment.
This change moves that logic out of GlobalSettings so that the returned theme IDs are correct for the current site.
Uses get_set_cache, which ultimately uses DistributedCache, which will take care of multisite issues for us.
* DEV: Show warning message when using ember css selectors
When editing the theme css via the admin UI a warning message
will be displayed if it detects that the `#emberXXX` or `.ember-view`
css selectors are being used. These are dynamic selectors that ember
generates, but they can change so they should not be used.
* Update error message text to be more helpful
* Display a warning instead of erroring out
This allows the theme to still be saved, but a warning is displayed.
Updated the tests to check for the error message.
Updated the pre tags css so that it wraps for long messages.
This results in some fun disasters if allowed to happen. For now, just issue an oblique error message; a localized message will be added on the client.
Allowing the editing of remote themes has been something Discourse has advised against for some time. This commit removes the ability to edit or upload files to remote themes from Admin > Customize to enforce the recommended practice.
In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.
* FIX: randomize file name when created from fixtures
When a temporary file is created from fixtures it should have a unique name.
It is to prevent a collision in parallel specs evaluation
* FIX: use /tmp/pid folder to keep fixture files
### General Changes and Duplication
* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file.
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.
### Viewing Secure Media
* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`
### Removed
We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.
* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.
* FEATURE: Ability to add components to all themes
This is the first and functional step from that topic https://dev.discourse.org/t/adding-a-theme-component-is-too-much-work/15398/16
The idea here is that when a new component is added, the user can easily assign it to all themes (parents).
To achieve that, I needed to change a site-setting component to accept `setDefaultValues` action and `setDefaultValuesLabel` translated label.
Also, I needed to add `allowAny` option to disable that for theme selector.
I also refactored backend to accept both parent and child ids with one method to avoid duplication (Renamed `add_child_theme!` to more general `add_relative_theme!`)
* FIX: Improvement after code review
* FIX: Improvement after code review2
* FIX: use mapBy and filterBy directly
