isnt and is_in validation message error

[nioperas06]

users = User.all()
...
isnt(
       is_in('email', users.pluck('email'))
),

The email must not contain an element in <orator.orm.collection.Collection object at 0x10752e198>
Having something this would be better The email has already been taken. or The email is taken.

It's a bit tricky with this one because you migth want to use isnt(is_in()) for multiple cases :

• You want to ensure that a value is not in a list => the error message would be in case of error : "value Y is in list X"*
• You want to ensure that email is not used by registered users => the error message, as you said, would be : "email is already taken".

We want to be able to use both I guess.

Maybe solutions are :

• override messages in your project for this validation rule (if not possible then it's a good feature to add because some people would want other messages for their project !)
• create a specific validator for this case and try to abstract User model fetching ... ?

@nioperas06 what do you think ?

We could just add a new validation rule called not_taken('email') and tie into the database somehow like not_taken('input_field', 'table.column') so would look something like not_taken('email', 'users.email')

[girardinsamuel]

Yes why not ! I'll try to do it ;)

[josephmancuso]

I'm not 100% sure how this will be done with connecting to a database within this project

@girardinsamuel thinking more about this it might need to be an import from the masonite project.

[girardinsamuel]

Yes that could work.
I was thinking/experimenting about converting users got from path in the validation rule, into a n import from Masonite.

For further information see #43.
It will be added into Masonite core, so this issue should now be closed.
