symfony - DataTransformer for IvoryGoogleMapBundle autocomplete (array) to an Address Entity -

i added autocomplete field registrationformtype (fosuserbundle) using ivorygooglemapbundle.

an user can have 1 address => onetoone relation

i created datatransformer transform autocomplete field (array) address entity following symfony documentation seems missed :(

i have following error: the required option "em" missing.

i don't know if right , easiest way save autocomplete field address entity...

thank help

i see 2 issues in code. first 1 (not important), should rely on di component (container) create form type when needs dependency. see http://symfony.com/doc/current/cookbook/form/create_custom_field_type.html#creating-your-field-type-as-a-service more details.

this way, able make dependency explicit (your object manager can directly pass constructor of form type instead of passing form option).

the second issue geocoder not created. here, create geocoder without provider. see comment more details https://github.com/egeloen/ivory-google-map/issues/32#issuecomment-20461264

then, awre if refactor form type service, geocoder provided bundle configured provider. injecting ivory_google_map.geocoder service enough.
