    <p>I have a dictionary database that works for many languages. The structure is like this:</p> <p>Table: English_words </p> <ul> <li>id </li> <li>word </li> <li>wordtype </li> <li>grammar </li> </ul> <p>Table: Spanish_words (same as for English)</p> <p>Table: French_words (same as for English)</p> <p>Table: English_Spanish </p> <ul> <li>english_id </li> <li>spanish_id </li> <li>weight_english </li> <li>weight_spanish </li> <li>use_english_if </li> <li>use_spanish_if </li> </ul> <p>The last four columns are for helping my program decide which of the many possible translations are the best suited in a particular context. My English model contains </p> <pre><code>has_many :es_words, :through =&gt; :english_spanish, :order =&gt; 'weight_english ASC' </code></pre> <p>in order to get the possible Spanish translations in order of preference. Additionally, I later need to do some more complicated filtering based on the rules in the use_.._if columns. So whenever I write "this_word.es_words" to retrieve Spanish translations for an English word, I would like my resulting objects to also contain the use_.._if columns from the joining table. I cannot imagine ever needing just the translations without those columns, so I would like to solve this on a model level rather than in the controller. What is the best way to do it? </p> <p>(The reason I don't have use_if in the Spanish_words table is that I'm translating multiple languages, and the conditions will vary depending on what language I'm translating from/to)</p>

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.
