Guide: Export PDF

Tried to get my version of your program to work but temporality gave up and decided to try and work with yours to figure out what I am doing wrong. Having after I downloaded your GitHub repository and set it up which went ok. I try to delete a company and get the following Error.

 
SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`lvdy_reservations`.`activities`, CONSTRAINT `activities_company_id_foreign` FOREIGN KEY (`company_id`) REFERENCES `companies` (`id`))
 
delete from `companies` where `id` = 4
 
public function destroy(Company $company)
 
    {
 
        $company->delete();
 
 
 
        return to_route('companies.index');
 
    }

How can I fix this or better yeat sence it is your code can you?

Ok yes if you delete the activities first then you can delete the company so I thank we need to disable the company delete if there are any activities available what do you thank.

I'm getting an error on the test test_pdf_export, any ideas? I think it has something to do with the formatting, but not sure.
