    <p>I try to $this->MembersQuestionsAnswer->saveMany($data). </p> <p>And $data is this:</p> <pre><code>array( (int) 0 =&gt; array( 'member_id' =&gt; '4', 'questions_anwser_id' =&gt; '102' ), (int) 1 =&gt; array( 'member_id' =&gt; '4', 'questions_anwser_id' =&gt; '203' ) ) </code></pre> <p>then I got error</p> <blockquote> <p>Error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (<code>dating_sys</code>.<code>members_questions_answers</code>, CONSTRAINT <code>members_questions_answers_ibfk_2</code> FOREIGN KEY (<code>questions_answer_id</code>) REFERENCES <code>questions_answers</code> (<code>id</code>))</p> <p>SQL Query: INSERT INTO <code>dating_sys</code>.<code>members_questions_answers</code> (<code>member_id</code>, <code>modified</code>) VALUES (4, '2012-11-14 01:13:27')</p> </blockquote> <p>I checked the database. Both 102 and 203 do exist in table questions_answers id field. And I can also manually insert them into the table. Foreign key constraints work as I checked as well. </p> <p>And the table members_questions_answers table DDL is </p> <pre><code>CREATE TABLE `members_questions_answers` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `member_id` int(10) unsigned NOT NULL, `questions_answer_id` int(10) unsigned NOT NULL, `modified` datetime NOT NULL, PRIMARY KEY (`id`), KEY `member_fk` (`member_id`) USING BTREE, KEY `questions_answer_fk` (`questions_answer_id`) USING BTREE, CONSTRAINT `members_questions_answers_ibfk_2` FOREIGN KEY (`questions_answer_id`) REFERENCES `questions_answers` (`id`), CONSTRAINT `members_questions_answers_ibfk_1` FOREIGN KEY (`member_id`) REFERENCES `members` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ; </code></pre> <p>It feels like questions_answers table not really identified for some reason. I did have changed the name of this table and its foreign keys references. Is there a cache or something?</p> <p>Can anyone help or point me to a new way to look into?</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.
