In this part of the series (Implementing CRM with laravel) we will generate the eloquent models and setup up relations between tables.

Series Topics:

• Part 1: Preparation
• Part 2: Database
• Part 3: Models & Relations
  
• Part 4: Preparing Login Page
  
• Part 5: Users Module
  
• Part 6: Roles & Permissions
  
• Part 7: Documents Module
  
• Part 8: Contacts Module
  
• Part 9: Tasks Module
  
• Part 10: Mailbox Module
  
• Part 11: Mailbox Module Complete
  
• Part 12: Calendar Module
  
• Part 13: Finishing

Let’s generate the eloquent models using the laravel artisan commands, at first create a new directory inside the app/ directory called “Models“. This directory will contains our models, next run these commands one after the other:

php artisan make:model Models/Contact
php artisan make:model Models/ContactDocument
php artisan make:model Models/ContactEmail
php artisan make:model Models/ContactPhone
php artisan make:model Models/ContactStatus
php artisan make:model Models/Document
php artisan make:model Models/DocumentType
php artisan make:model Models/Setting
php artisan make:model Models/Task
php artisan make:model Models/TaskDocument
php artisan make:model Models/TaskStatus
php artisan make:model Models/TaskType

Now after we generated the models we will list all the model code below along with the relations according to the Database Diagram that we created in the previous part2.

As shown the code the relations is self explanatory as most of the relations is a one to many relationships like createdBy(), modifiedBy(), assignedTo() and there are some of them which is a many to many like Contact::documents() and Task::documents().

The most important part is the relations in the user model, as a sales person i must have the capability to view my contacts, leads and opportunities also view my tasks whether completed or pending, for this reasons we add relations like User::contacts(), User::leads(), User::tasks, etc.

Now let’s move on to the next part to prepare the authentication.
