    <p>I'm trying to share a session variable in both the controllers, the views and the model.</p> <p>With the following code, it is working in the controllers and in the views :</p> <pre><code>class ApplicationController &lt; ActionController::Base protect_from_forgery helper_method :best_language_id # Returns the ID of the language to use to display the description. def best_language_id @best_language_id ||= session[:best_language_id] @best_language_id ||= current_project.default_language.id return @best_language_id end end </code></pre> <p>But I can't call it from the model.</p> <p>I would like to be able to call best_language_id either in the controllers, views and in one model, to get a fallback of the best_language_id if a translation is not found.</p> <p>Example in my model (not working) : </p> <pre><code>class Point &lt; ActiveRecord::Base # Retuns the attached word in the given language if exists. # Otherwise, falls back on another translation def word(preffered_language_id) word = Word.find(:translation_id =&gt; self.translation_id, :language_id =&gt; preffered_language_id) if word.blank? word = translations.where(:translation_id =&gt; self.translation_id, :language_id =&gt; best_language_id) end return word end end </code></pre> <p>I know that model should not include applicationcontroller method calls, but how is it possible to share my best_language_id accross controllers and model ?</p> <p>Edit : using i18n is not the question here. Translations are not fixed string but variables in a database.</p> <p>Thanks for helping !</p>

    1. COyou're wrong: you could have an ActiveRecord I18n store

    2. COI understand your comment, but as I said, i18n is not the question here because we would like to handle ourselves the vocabulary. Do you have an idea to solve my question ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
