I'm having some difficulty setting up Doctrine and am hoping some guru's can give me a hand. If I try to save a MainEntity on its own, it works fine. However, if I add a "tag" to the tags collection of this entity, I get an error. Here is my info: I have entities that are similar to this <pre><code>namespace CG; class Content { public $id; public $tags; public function __construct() { $this->tags = new ArrayCollection(); } } /* this is single table inheritance */ class Tag extends TagAssociation { public $id; public $term; public $content; } class Term { public $id; public $name; } </code></pre> Mapping <pre><code><doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd"> <entity name="CG\Content" table="cg_content"> <id name="id" type="integer" column="Id"> <generator strategy="AUTO" /> </id> <one-to-many field="tags" target-entity="CG\Tag" mapped-by="tagContent"> <join-column name="ContentId" referenced-column-name="Id" nullable="false" fetch="FETCH" /> <cascade> <cascade-persist/> </cascade> </one-to-many> </doctrine-mapping> <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd"> <entity name="CG\Tag" table="cg_contenttags">  <many-to-one field="tagContent" target-entity="CG\Content" inversed-by="tags"> <join-column name="ContentId" referenced-column-name="Id" /> </many-to-one> </entity> </doctrine-mapping> <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd"> <entity name="CG\Term" table="cg_tags"> <id name="id" type="integer" column="Id"> <generator strategy="AUTO" /> </id> <field name="name" column="Name" type="string" /> </entity> </doctrine-mapping> <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd"> <entity name="CG\TermAssociation" table="cg_contenttags" inheritance-type="SINGLE_TABLE">  <id name="id" type="integer" column="Id"> <generator strategy="AUTO" /> </id> <discriminator-column name="TaxonomyId" type="integer" /> <discriminator-map> <discriminator-mapping value="1" class="CG\Tag" /> <discriminator-mapping value="2" class="CG\Category" /> </discriminator-map> <many-to-one field="content" target-entity="CG\Content" > <join-column fetch="FETCH" name="ContentId" referenced-column-name="Id"/> </many-to-one > <many-to-one field="term" target-entity="CG\Term" > <join-column fetch="FETCH" name="TagId" referenced-column-name="Id" /> <cascade> <cascade-persist/> </cascade> </many-to-one > </entity> </doctrine-mapping> </code></pre> finally, here are the errors I am getting <pre><code>( !

If not, I create a new content object</li> <li>copy over the fields from the json object to my content object</li> <li>call $content->tags->clear()</li> <li>loop through each of the tags in the json object.

Done.</li> <li>If not, see if there is a term in the database that matches the termName. If so, create a new tag, assign the term and content to it, and add it to tags. Done.</li> <li>if not, create a new tag and a new term, assign the term and content to it, and add it to tags. Done.</li> </ol></li> </ol> Doing a var dump shows that my $content object is as expected. Edit 2: Solved My content object wasn't as expected after all. I had added an array to the tags collection rather than a CG\Tag.

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.
