This change introduces polymorphic comments, allowing you to comment on Photos, Plantings, Harvests, and Activities, in addition to Posts.
Key changes include:
- **Comment Model:**
- Made `Comment.commentable` a polymorphic association.
- Added a data migration to move existing post comments to the new structure.
- Updated notification creation logic for polymorphic commentables.
- **CommentsController:**
- Refactored to handle various commentable types using a `find_commentable` method.
- **Ability Model:**
- Updated permissions for comment creation, editing (author/admin), and deletion (author/commentable owner/admin).
- **Routes:**
- Added nested comment routes for Photos, Plantings, Harvests, Activities, and Posts using a `commentable` concern with shallow routes.
- **Views:**
- Created generic partials for comment forms (`_form.html.haml`) and display (`_comment.html.haml`, `_comments.html.haml`).
- Integrated these partials into the show pages of all commentable types.
- Updated `comments/new` and `comments/edit` views to be generic.
- Relevant parent controller `show` actions now eager-load comments.
- **Testing:**
- Added extensive model, controller (using shared examples), and feature tests to cover the new polymorphic comment functionality, including permissions and UI interactions for all commentable types.
- Updated and created factories as needed.
This fulfills the issue requirements for adding comments to multiple resource types with appropriate permissions.

# The `respond_with @comment, location: @comment.commentable` will try to redirect if valid.

|
# If invalid, it should re-render the action that led to the form.
|
|
# For `create` failing, it's often the `new` view or the parent resource's view.

# The controller has `respond_with @comment, location: @comment.commentable`.
|

# If `@comment` is not persisted, `respond_with` might render the `new` template by convention,

|
# or the template of the action (`create.js.erb` or `create.html.erb` if they exist).
|
|
# Given the setup, it's likely to re-render 'new' or the controller action's default.

# This is a weak assertion. A better one would be to check for `render_template(:new)`

# if the controller is set up to do that on failure.
|
|
# However, `respond_with` is tricky. It might also render the `commentable` show page with errors.
|
|
# The `new` action in controller renders `respond_with(@comment)`.
|
|
# The `create` action has `respond_with @comment, location: @comment.commentable`.
|
|
# If `@comment.save` fails, `respond_with` will typically render the `new` template by default
|
|
# if `create.html.haml` doesn't exist, or it might try to render `commentable` show page
|
|
# with errors displayed by the form partial.
|
|
# Given the form is rendered via `comments/new`, let's assume it re-renders new.
