SimpleSchema unable to set specific error message for given validation

I have this very basic model with just one field name that I want to validtate against a regex:

const Projects = new ProjectsCollection('projects');

Projects.schema = new SimpleSchema({
    _id         : {type: String, regEx: SimpleSchema.RegEx.Id},
    name        : {
        type : String,
        regEx: /^[a-zA-Z0-9]+((\s[a-zA-Z0-9]+)|(_[a-zA-Z0-9]+)|(-[a-zA-Z0-9]+)|(\.[a-zA-Z0-9]+))?$/
    }
});

Projects.attachSchema(Projects.schema);

When the validation fails I get back a validation error saying that regex failed for Name which is undesirable for me because it's ambiguous and the user has no idea what exactly I need him to enter.

I tried adding the following with no success:

Projects.schema.messages({
    "regEx name": [{
        msg: "test error message"
    }]
});

This one however..works but the problem is that I could have any other model with a name field and it will spit out the same error message for all of them (and I plan on having another model with a name field):

SimpleSchema.messages({
    "regEx name": [{
        msg: "test error message"
    }]
});

I tried also with (no success):

SimpleSchema.messages({
    "regEx projects.name": [{
        msg: "test error message"
    }]
});

I insert via methods and here's my insert code:

export const insert = new ValidatedMethod({
    name                  : 'projects.insert',
    mixins                : [simpleSchemaMixin],
    schema                : Projects.simpleSchema().pick([
        'name'
    ]),
    schemaValidatorOptions: {
        clean : true,
        filter: false
    },
    run({name}) {
        return Projects.insert({
            name
        }, null);
    },
});

Any ideas on how am I supposed to configure my validation messages so that I can target them for specific fields?

This answer and question applies to v1 of meteor-simpl-schema

I had the same problem and this worked for me. I think that custom messages are instance based - are bound only to one simplSchema instance. Then in your validated-method, pick() will create a new SimplSchema instance, without your custom messages.

I needed to manually add a custom messages from the "parent" schema. In your case like this:

const insertProjectSchema = Projects.schema.pick('name');
insertProjectSchema.messages(Projects.schema._messages);

export const insert = new ValidatedMethod({
    name                  : 'projects.insert',
    mixins                : [simpleSchemaMixin],
    schema                : insertProjectSchema,
    schemaValidatorOptions: {
        clean : true,
        filter: false
    },
    run({name}) {
        return Projects.insert({
            name
        }, null);
    },
});

See the documentation for the special case of regex messages:

In your case you should try:

Projects.schema.messages({
  "regEx name": [
    {
      exp: /^[a-zA-Z0-9]+((\s[a-zA-Z0-9]+)|(_[a-zA-Z0-9]+)|(-[a-zA-Z0-9]+)|(\.[a-zA-Z0-9]+))?$/ , 
      msg: "test error message"
    }
  ]
});
