In our last blog, you learned how to create One to One data associations<\/a> for your entities. In this blog, you will learn about One to Many & Many to One<\/p>\n\n\n\n

Let\u2019s start with the process of creating data associations in Shopware 6.<\/span><\/p>\n\n\n\n

For this, you will use two entities \u201cFirstentity\u201d<\/strong>  and \u201cSecondentity\u201d<\/strong> (which was created in our last blog please refer to that blog “How to create data associations(One to One) in Shopware 6<\/u><\/strong><\/a>“<\/p>\n\n\n\n

Now we will see our data associatons example first is \u201cOne to Many\/Many to One\u201d<\/strong> associations. One to Many\/Many to One associations require you need to define a foreign key for \u201cMany to One\u201d. E.g. the Secondentity table has multiple records for the Firstentity table, Therefore you have to add the first_id column to the Secondentity table: In this example, it will be second_id in the FirstentityDefinition<\/p>\n\n\n\n

<\/span>Now We Will Look At The Example:<\/strong><\/span><\/h2>\n\n\n\n

Emizentechplugin\/src\/Core\/Content\/Firstentity\/FirstentityDefinition.php<\/strong><\/p>\n\n\n\n

Note:<\/strong> also add the use statement for SecondentityDefinition and OneToManyAssociationField*<\/p>\n\n\n\n

protected function defineFields(): FieldCollection\n{\n\nreturn new FieldCollection([\n\n(new IdField('id', 'id'))->addFlags(new Required(), new PrimaryKey()),\n\nnew OneToManyAssociationField('secondentity', SecondentityDefinition::class, 'first_id')\n\n]);\n\n}<\/code><\/pre>\n\n\n\n
\"Hire<\/a><\/figure><\/div>\n\n\n\n
<\/span>Parameters Of One-To-Many Association Field<\/span><\/h2>\n\n\n\n
<\/span>1. Secondentity<\/span><\/h3>\n\n\n\n
It s the property that will contain all secondentity\u2019s the class name of SecondentityDefinition.<\/p>\n\n\n\n
<\/span>2. first_id<\/span><\/h3>\n\n\n\n
The name of the column in the referenced table points to the definition itself.<\/p>\n\n\n\n
Now you will add code for the Secondentity for completion of the ManytoOne association example.<\/p>\n\n\n\n
Emizentechplugin\/src\/Core\/Content\/Secondentity\/SecondentityDefinition.php<\/strong><\/p>\n\n\n\n
Note:<\/strong> also add the use statement for FirstentityDefinition and ManyToOneAssociation*<\/p>\n\n\n\n
protected function defineFields(): FieldCollection\n{\n\nreturn new FieldCollection([\n\n(new IdField('id', 'id'))->addFlags(new Required(), new PrimaryKey()),\n\n(new FkField('first_id', 'firstId', FirstentityDefinition::class))->addFlags(new PrimaryKey(), new Required()),\n\nnew ManyToOneAssociationField('Firstentity', 'first_id', FirstentityDefinition::class, 'id', false),\n\n]);\n\n}<\/code><\/pre>\n\n\n\n
<\/span>For Many-To-One Association<\/span><\/h2>\n\n\n\n
first_id: new FkField, which is the field for the new first_id column.<\/p>\n\n\n\n
<\/span>Many-To-One AssociationField Parameter<\/span><\/h2>\n\n\n\n
Firstentity: You have to apply the name of the property, which will contain the single FirstentityDefinition(Entity name or table name)
first_id: The name of the column, which references the inverse side entity.
FirstentityDefinition: The class of the referenced definition and the name of the ID column in the definition’s database table itself.<\/p>\n\n\n\n
Now you have completed your One to Many & Many to One association. For Many to Many, it will be covered in our next blog.<\/p>\n\n\n\n
