Technické informace

The AfterInstall class is located in scripts/AfterInstall.php and implements the following key functionality:

• Dependency Injection: Loads required dependencies through the EspoCRM container system using InjectableFactory. Key dependencies include:

• Config - For accessing system configuration

• ConfigWriter - For modifying configuration values

• EntityManager - For database operations

• DataManager - For cache management

• Module Dependency Checking:

• Uses REQUIRED_MODULES constant to define required modules and their version constraints

• Validates installed modules against these requirements using checkModuleDependencies()

• Implements complex version comparison logic in satisfiesVersionRequirement() supporting operators: \≥, \≤, !=, \>, \<, ^, ~

• Configuration Management:

• defaultConfig() - Applies default configuration values from DEFAULT_CONFIG constant

• addEntitiesToTabList() - Adds entities defined in TAB_LIST_ENTITIES to the navigation tab list

• Record Creation:

• createDefaultRecords() - Creates default records defined in DEFAULT_RECORDS constant

• Uses EntityManager to create entities with duplicate checking

• Implements complex query building using Condition and Expression

• Cache Management:

• clearCache() - Clears system cache through DataManager

The script differentiates between fresh installs and upgrades using the isUpgrade parameter in the run() method.
