Gettext not working with validate_length

Maybe are you editing the wrong message in your errors.po?
Did you translate all the messages ?

I think the validate_length is handled by multiple messages:

msgid "should be %{count} character(s)"
msgid "should be at least %{count} character(s)"
msgid "should be at most %{count} character(s)"

Have you all that translated ?

Maybe show us what it looks like the part of the file you edited.

No I used the correct translation can you reread the question I have added more information

Oh I see ! You are using a custom error message. In that case you should use a gettext backend in your changeset like this:

|> validate_required([:password], message: MyApp.Gettext.gettext(“test validate required”))

Then of course you will use mix gettext to extract the new message into your po files. You don’t have to add the msgid by hand.

While useful for being able to extract those strings, that shouldn’t be necessary at all. MyAppWeb.ErrorHelper will run any ecto error through a translation step.

Ah, thanks for pointing this. I didn’t know that.

Great this worked with dgettext but not with gettext
like the following

|> validate_length(:password, min: 12, max: 72, message: MyAppWeb.Gettext.dgettext("errors", "test validate length %{count}"))

But the maximum limit, should have another message

I tried to reproduce the issue you are facing and this is what I can say.

1- Adding bare custom message in the validate_length without gettext then editing by hand errors.pot then merging the new msgid with mix gettext.merge into errors.po won’t work.

2- Importing MyApp.gettext/1 in the changeset and passing the message through it, work as expected. In my case after running mix gettext.extract --merge and adding the translation in default.po work. I can see you’ve done something similar but with dgettext.

Now if you want to customize your message depending on the kind of error then just add multiple validations:

|> validate_length(:password, min: 12, message: dgettext("errors", "too short"))
|> validate_length(:password, max: 72, message: dgettext("errors", "too long"))

I didn’t test this but I guess it should work.

Edit :

I realise you were saying that you are not getting the same error message as expected. That is weird, when I pass min and max in the same validation options I have the same error message as expected. I just tested it right now.

Yes dgettext can extract your messages in specific domain file such as errors.pot. But if you just use gettext then they will be found in default.pot and default.po.
