Taxonomy vocabulary = Company activity (Activity 1, Activity 2, Activity 3 ….). This vocabulary has an OG group field.
Content type 1 = Company with an entity (terms) reference field showing the list of the terms of the activity vocabulary. The widget is “radio button box” and the administrator of the Company, during the creation of the content, may tag and save the appropriate activities performed. This content type has an OG group field. Example: Company 1 --> tag Activity 1 and Activity 2 – Company 2 --> tag Activity 1 and Activity 3
Content type 2 = Request of Service. Any Company can create a new request of service and first of all choose the needed activity in a entity (terms) reference field (fiel_tipologia_macchina) showing the list of the terms of the activity vocabulary. The widget is “selection list” – only one choice. This content type has an OG group audience field.
Now the question: In Content type 2 (request of service) I need to add a field that show the Company qualified to perform the requested service. Example: the service requested is “Activity 1” --> show Company 1 and Company 2.
The field has to be a radio button box so the author of the request can choose the company to send the request (one or more company).
I think that I have to use a view (page or block) but I am not able to find the right relation and contextual filters (entity reference or OG).
Thank you in advance for help.
