Rule-based node creation: commerce product + product display node set - drupal

Question

I'm trying to bind a Commerce product type to my own custom type node (serving as a display node). The goal is to enter new data in as few places as possible. I'm therefore exploring a rule-based creation of one type upon creation of the other. Seems like both directions are working. Of the two though, I prefer automatic creation of a Commerce Product upon user creation of Custom Type node, which will then serve as a product display.
I was wondering if anyone has been through this choice and could recommend this. Also, is the commerce_product_display_manager module necessary?

Answer 1

Commerce Product Display Manager is not necessary, I've gotten this to work and I've never used that module.
I went for the route of automatically creating a Node after saving the Product.
Below is my Rules export for this:
{ "rules_create_product_display" : {
"LABEL" : "Create Product Display",
"PLUGIN" : "reaction rule",
"REQUIRES" : [ "rules", "entity" ],
"ON" : [ "commerce_product_insert" ],
"IF" : [
{ "data_is" : { "data" : [ "commerce-product:type" ], "value" : "**PRODUCT_TYPE**" } }
],
"DO" : [
{ "entity_create" : {
"USING" : {
"type" : "node",
"param_type" : "**NODE_TYPE**",
"param_title" : "[commerce-product:title]",
"param_author" : [ "commerce-product:creator" ]
},
"PROVIDE" : { "entity_created" : { "entity_created" : "Created entity" } }
}
},
{ "data_set" : {
"data" : [ "entity-created:**PRODUCT_REFERENCE**" ],
"value" : [ "commerce-product" ]
}
}
]
}
}
You'll need to substitute your own values for:
PRODUCT_TYPE (product type that has been created)
NODE_TYPE (node type being created)
PRODUCT_REFERENCE (field that will reference the created product)
Sorry I can't dedicate more time to a better answer now, let me know if you'd like me to elaborate on the process of creating the above using the GUI

Answer 2

The above example was useful but here is a more specific one:
{ "rules_create_product_display_on_product_creation" : {
"LABEL" : "Create Product Display on Product creation",
"PLUGIN" : "reaction rule",
"REQUIRES" : [ "rules", "entity" ],
"ON" : [ "commerce_product_insert" ],
"IF" : [
{ "entity_is_of_type" : { "entity" : [ "commerce-product" ], "type" : "commerce_product" } }
],
"DO" : [
{ "entity_create" : {
"USING" : {
"type" : "node",
"param_type" : "product_display",
"param_title" : "[commerce-product:title]",
"param_author" : [ "commerce-product:creator" ]
},
"PROVIDE" : { "entity_created" : { "entity_created" : "Created entity" } }
}
},
{ "data_set" : {
"data" : [ "entity-created:field-product:0" ],
"value" : [ "commerce-product" ]
}
}
]
}
}
The only problem I had was with the second action ("data_set")- it was important to select "entity-created:field-product:0", not the "entity-created:field-product" to make it work because we want to assign specific product and not a list of products.
This example is using the standard product display node type (product_display) but you can change it with the one you are using. Also have in mind that this is working only for one product type - for every product type a separated rule should be created. You may create also a rule for deleting the product display node when deleting the product.
This rule is useful only when you have connection one product-one product display. If you need to add more products per product display (colors, images with different prices) then you have to use Commerce Bulk Product Creation module.
