    <p>I am using rails 3 with mysql and am facing an issue with invalid characters when adding some text to my mysql db. </p> <p>Following is the mysql command causing issues (from my server log):</p> <pre><code>SQL (2.1ms) describe `shared_link_posts` AREL (0.4ms) INSERT INTO `posts` (`created_at`, `description`, `link`, `host_name`, `updated_at`, `content`) VALUES ('2011-07-05 00:54:51', NULL, 'http://foo.bar', 'foobar.com', '2011-07-05 00:54:51', 'foobar? foobar') </code></pre> <p>The issue is with the last value being added, namely <code>'foobar? foobar'</code>. The value added to the database is just <code>"foobar"</code>. Everything after and including the <code>"?"</code> is truncated, not added to the db.</p> <p>The <code>"?"</code> is an invalid character. It is \240 which in ascii corresponds to a hyphen.</p> <p>I was in the impression that rails uses parametrized sql queries which takes care of all these invalid characters when adding content to the mysql db. Does it not?</p> <p>How else can I solve this issue? I will be dealing with a lot of text that may or may not have invalid characters.</p> <p>Thanks!</p> <p>EDIT: The code I use to save to the db is simply just assigning a field this content. So it's basically:</p> <pre><code>post.content = body_content post.save! </code></pre> <p>body_content is <code>"foobar? foobar"</code></p> <p>EDIT:</p> <p>mysql> show variables like "character_set_database";</p> <pre><code>+------------------------+-------+ | Variable_name | Value | +------------------------+-------+ | character_set_database | utf8 | +------------------------+-------+ 1 row in set (0.11 sec) mysql&gt; show variables like "collation_database"; +--------------------+-----------------+ | Variable_name | Value | +--------------------+-----------------+ | collation_database | utf8_unicode_ci | +--------------------+-----------------+ 1 row in set (0.02 sec) </code></pre>

    3. COWhats the MySQL DB collation? If you use utf8_general_ci, there should be no problem.

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.
