Maybe it is possible to use this option effectively?

Tasks:

• is there any way to access schema's data from types's autogenerate/0?
• is possible to call functions such as get_sources/2 from autogenerate/0?
• is it even reasonable?

Following your tut, I only get: ** (ArgumentError) invalid or unknown type TitleSlug.Type for field :slug.
Any Idea?
Thanks

We need to release a new version with ecto@3 support.

Help is wanted, since I don't have much time to work on this issue.

Hi,
maybe you could use the new function

Slugger.truncate_slug(slug, max_length, options \\ [])

which is part of slugger v0.2.0. 💃

Here's the error:

lib/ecto_autoslug_field/slug.ex:3:no_return
Function build_slug/1 has no local return.
________________________________________________________________________________
lib/ecto_autoslug_field/slug.ex:3:no_return
Function build_slug/2 has no local return.
________________________________________________________________________________
lib/ecto_autoslug_field/slug.ex:218:call
The function call will not succeed.

EctoAutoslugField.SlugBase.build_slug(_ :: any(), nil)

will never return since the 2nd arguments differ
from the success typing arguments:

(Keyword.t(), %Ecto.Changeset{
  :action => atom(),
  :changes => %{atom() => _},
  :constraints => [
    %{
      :constraint => binary(),
      :error_message => binary(),
      :error_type => atom(),
      :field => atom(),
      :match => :exact | :prefix | :suffix,
      :type => :check | :exclusion | :foreign_key | :unique
    }
  ],
  :data => nil | map(),
  :empty_values => _,
  :errors => Keyword.t({_, _}),
  :filters => %{atom() => _},
  :params => nil | %{binary() => _},
  :prepare => [(_ -> any())],
  :repo => atom(),
  :repo_opts => Keyword.t(),
  :required => [atom()],
  :types =>
    nil
    | %{
        atom() =>
          atom()
          | {:array | :assoc | :embed | :in | :map | :maybe | :param, _}
          | {:parameterized, atom(), _}
      },
  :valid? => boolean(),
  :validations => Keyword.t()
})

I'm using the library according to the docs.

def get_sourses
Should be:
def get_sources

I wanted to ask that in implementing the unique constraint for lets say a post title to be converted to a slug, is it possible that if a title already exists with the same words/characters then while creating a new post, it adds random characters or numbers at the end to differentiate the post slugs.

In rails the FriendlyId gem takes care of this. As an example I am posting images from a rails app using FriendlyId to create slugs from the post's title.

Second post created with the same title:

Any help on this will be appreciated.

Hello,

Let's say I want to force the regeneration of a slug on a particular record without having to set globally the always_change option, what's the short way of doing that?
What do you think of having a function called force_generate_slug?

Thanks.

Hi,

slug.ex is causing Dialyzer errors for me:

lib/ecto_autoslug_field/slug.ex:2: Function get_sources/2 has no local return
lib/ecto_autoslug_field/slug.ex:168: The pattern 'nil' can never match the type 'name'

Thanks!

Hey, just noticed: you have CHANGELOG link broken in your README.

PS: thanks for your work)

See this issue: rrrene/credo#210

It is temporary disabled.

Currently we only test this app against:

elixir:
  - 1.4
  - 1.5

But, there are new elexir version available. We should test how this app works with 1.6 and 1.7.
Related to #54

Starting point: https://github.com/sobolevn/ecto_autoslug_field/blob/master/.travis.yml

I guess functions like this could be just delegated: https://github.com/sobolevn/ecto_autoslug_field/blob/master/lib/ecto_autoslug_field/slug.ex#L21

We need to test it in travis.

It is not tested.

Hi,

I've been attempting to apply the tutorials to the following project: https://github.com/blcksheep80/blcksheepio-api

However, I can't seem to get the slug to generate? I created a field: https://github.com/blcksheep80/blcksheepio-api/blob/master/lib/blcksheepio_api/classification/fields/name_slug.ex

Which I've attempted to apply to https://github.com/blcksheep80/blcksheepio-api/blob/master/lib/blcksheepio_api/classification/category.ex

However, whenever I attempt to insert a new category I get the following back:

Hello,

Thanks for the great lib
In my use case the same slug can be generated. When that happens the unique constraint kicks in and fails the changeset.

I would like instead to try to insert the same entity with a auto incremented number

For example:

changeset = Todo.changeset(Todo, %{text: "My Todo"})
todo = Repo.insert!(changeset)

Should return:

%Todo{text: "My Todo", slug: "my-todo"}

If I run the same insert again, I want to get back:

%Todo{text: "My Todo", slug: "my-todo-2"}

Any tips on how to achieve that?
Is this feature planned for this library?

Thanks,
Ran.

I think you must publish the latest version from main of this package.
