在Rails表单参数名称中编码UTF-8

Question

I'm having a problem with my params. I'm receiving the following parameters:

{"utf8"=>"✓", "authenticity_token"=>"...=", "Portugu\xC3\xAAs"=>{"title"=>"313" } }

In my controller I need to use the key => "Portugu\\xC3\\xAAs", but first I need it to be in the right form (that is -> Português) and I don't know how can I do that.

EDIT:

Workflow 1. The user saves a language 2. I use that language in a form to save information, like this:

Português[title]

3 . Because the user can have multiple locales in that form (all the locales saved in step 1)

locales.each do |locale|
 ...
 :value => params[locale.key][:title]

The problem is that locale.key ('Português') doesn't match with "Portugu\\xC3\\xAAs" so it crashes with nil

Can you help me with this? Thank you

Answer 1

I've tried this, and the result is good:

    <% p = {}
       p["Português"] = {}
       p["Português"][:title] = "Title in Portugês" %>
    <p><%= p["Portugu\xC3\xAAs"][:title] %>

And I get

<p>Title in Portugês</p>

I don't see the problem.

The solution that worked for me was iterating the received params and with the help of URI.escape compare the string, if matches enc_locale is set and used in the value. Thanks to everyone that helped!

    enc_locale = ""
    params.each do |param|
      if URI.escape(param[0]) == URI.escape(locale.key)
        enc_locale = param[0]
      end
    end

   ...
   :value => params[enc_locale][:title]
