Module development and code questions

Hello,

I'm trying to look for a solution for the following problem :

On a website, i have two views which displays results of the same content type.

On the front page they are displayed one after the other, and i store the nids of the first view results in $_SESSION.
The query of the second block is altered based on the nids stored in session so that we don't get duplicate results.

This is undoubtedly a hot topic and I have read many web pages on "best development practices" for Drupal with respect to the use of git. The background is that this will be a multi-developer project with three repositories on the server: development, staging and production. The branching model to be used in Git will follow "A successful Git branching model" found on the web.

On Drupal 7 with the schema module in use. Get this error- "One of offers or review or aggregateRating should be provided"       I know we can get a fully validated test return by manually writing the review schema (and entering it in the Google validator), but cannot eradicate this error using any (intuitive) combination of settings in the Drupal module.   Q's     1. Is this a known problem/Is there any solution?    2. Is there an example somewhere of exactly how to create a 'review' schema in the module that will pass the validator test?

Good Day, comrades!

i have two Drupal 7 Form modules.

First one has field(one of many):

I installed the paragraphs module and inserted the paragraphs field (Entity reference revisions) in a content type called Anagrafiche with the name field_sedi. For some registries (nodes) I have entered multiple locations, the field_sede field (in the paragraph) is linked with an entity reference to the locations.
