Question 1

How to generate slugs from multiple fields in EctoAutoslugField?

Accepted Answer

Override the `get_sources/2` function in your slug module to return a list of field names. For example, `def get_sources(changeset, _opts), do: [:title, :author]` will combine both fields for slug generation, as explained in the README.

Question 2

Does EctoAutoslugField work with Ecto 4?

Accepted Answer

No, EctoAutoslugField only supports Ecto versions from 3.7 up to but not including 4.0, as specified in the README. For Ecto 4+, you'll need alternatives or consider forking the library.

Question 3

How to make slugs only update when the source field changes?

Accepted Answer

Set the `always_change` option to false when defining the slug module. With `always_change: false`, slugs are regenerated only when the specified source fields in the changeset are modified, based on the README documentation.

Question 4

EctoAutoslugField vs manually coding slugs in Elixir?

Accepted Answer

EctoAutoslugField automates slug generation within Ecto changesets, reducing boilerplate and providing hooks like `get_sources/2` for customization. Manual coding offers full control but requires more maintenance and error handling for each schema.

Question 5

How to handle unique slug constraints with EctoAutoslugField?

Accepted Answer

Use the `unique_constraint()` function provided by the slug module in your changeset. In the example, `TitleSlug.unique_constraint()` ensures slug uniqueness in the database, integrating seamlessly with Ecto's constraint handling.

Question 6

Can I use a custom slug engine instead of slugify in EctoAutoslugField?

Accepted Answer

Yes, by overriding the `build_slug/2` function, you can implement any slug generation logic. The default uses slugify, but you can replace it with custom code or another library, as mentioned in the README's customization options.
