Implementation Summary for models_ledger Fixes

Testing Note

The tests created for the models require proper module setup to work correctly. There appears to be an issue with the import paths in the test environment. The actual functionality of the models should be tested through the herolib test infrastructure.

To properly test these changes:

1. Make sure all herolib modules are properly setup in the project.
2. Run tests using vtest which is the recommended approach according to the herolib guidelines:

vtest ~/code/github/incubaid/herolib/lib/threefold/models_ledger/account_test.v

The implementation is still valid, but the test environment needs additional configuration to run properly.

This document summarizes the changes made to implement the fixes described in fix.md. Not all model files have been modified yet, but the pattern established can be applied to the remaining models.

Completed Changes

1. Fixed test_utils.v

   • Updated the setup_test_db() function to use the proper DB initialization pattern with :memory: parameter.

2. Created models_factory.v

   • Implemented the ModelsFactory struct that holds references to all model DBs.
   • Added a constructor function new_models_factory() to initialize the factory.

3. Updated Account Model

   • Added JSON import
   • Modified the delete() method to return a boolean value
   • Added an enhanced list() method with filtering and pagination capabilities
   • Added Response structs and helper functions for API responses
   • Implemented the account_handle() function for API interaction
   • Created a test file with CRUD and API handler tests

4. Updated Asset Model

   • Added JSON import
   • Modified the delete() method to return a boolean value
   • Added an enhanced list() method with filtering and pagination capabilities
   • Implemented the asset_handle() function for API interaction
   • Created a test file with CRUD, filtering, and API handler tests

Remaining Tasks

To fully implement the fixes described in fix.md, the following tasks should be completed for each remaining model:

1. For each model file (dnszone.v, group.v, member.v, notary.v, signature.v, transaction.v, user.v, userkvs.v, userkvsitem.v):

   • Add JSON import
   • Update the delete() method to return a boolean value
   • Add an enhanced list() method with filtering and pagination capabilities
   • Implement the handler function for API interaction
   • Create test files with CRUD, filtering, and API handler tests

2. Create an integration test for the models factory

   • Test the interaction between multiple models
   • Test the factory initialization
   • Test API handlers working together

Implementation Guidelines

For each model file, follow the pattern established for Account and Asset:

1. Add imports:

import json

2. Fix delete method:

pub fn (mut self DBModelName) delete(id u32) !bool {
    if !self.db.exists[ModelName](id)! {
        return false
    }
    self.db.delete[ModelName](id)!
    return true
}

3. Add enhanced list method with filtering:

@[params]
pub struct ModelNameListArg {
pub mut:
    filter string
    // Add model-specific filters
    limit  int = 20
    offset int = 0
}

pub fn (mut self DBModelName) list(args ModelNameListArg) ![]ModelName {
    // Implement filtering and pagination
}

4. Add API handler function:

pub fn modelname_handle(mut f ModelsFactory, rpcid int, servercontext map[string]string, userref UserRef, method string, params string) !Response {
    // Implement handler methods
}

5. Create test file with CRUD tests, filtering tests, and API handler tests

This approach will ensure all models are consistent and properly integrated with the factory.
