Error_messages_for i18n not working as expected

#1545

I've got some trouble translating the model name in the error string of error_messages_for. I'm not sure if it is a bug or me not understanding the inner workings of rails. The situation is as follows.


nl:
  activerecord:
    models:
      changed_organization: bedrijf
    errors:
      template:
        header:
          one: "1 error on {{model}}"
          other: "{{count}} errors on {{model}}"

Now when I call


error_message_for :changed_organization

I expect to get the following result "1 error on bedrijf" instead I get "1 error on changed organization"

When we look at the code in active_record_helper (lines 196,197)


object_name = options[:object_name].to_s.gsub('_', ' ')
object_name = I18n.t(object_name, :default => object_name, :scope => [:activerecord, :models], :count => 1)

we see that rails first gsubs the underscore to a space and then tries to find a translation for this gsubbed string. I would have expected to first try to find the translation for the non gsubbed string and use the gsubbed string as the default value. YAML files, as far as I know, can't handle keys with spaces so this won't ever work would it? My suggestion would be something like the following


object_name = options[:object_name].to_s.gsub('_', ' ')
object_name = I18n.t(options[:object_name].to_s, :default => object_name, :scope => [:activerecord, :models], :count => 1)

Can somebody help me out here, is it a bug or not?

Most of us got this stuff successfully working.

I think we should close for now

I want to clarify the initial statement: ActiveRecord has two methods to get the model- and attribute-names i18n'ed: :human_name and :human_attribute_name both use klass.name.underscore to get the default. Latter is used by :full_messages, which is used in :error_messages_for.

So, why should :error_messages_for itself search with "model name" whereas every other code in the app uses "model_name"?

The locale would have to look like this: en: activerecord:
```
models:
  model name: "Thingy" # just to satisfy error_messages_for
  model_name: "Thingy" # used by the rest of the app
attributes:
  model_name:
    column: "Something"
```
My selfmade solution is similar to above suggestion: overwrite :error_messages_for and change the two lines in question to something like:
```
object_name = options[:object_name].to_s
object_name = I18n.t(object_name, :default => object_name.gsub('_', ' '), :scope => [:activerecord, :models], :count => 1)
```

Hy,

I can confirm this strange behaviour. In my opinion the translation file should be clean and straightforward (no doubles with & without spaces). And I've learned the convention is that keys are underscored_names and not spaced names.

The attachment contains a diff that fixes the issue. (I've made the same correction like Stefan Achatz did)

Cheers, Lukas Rieder

This was fixed some time ago (yes!), you can see that this behavior cannot be reproduced on master.
