[Feature request] pac code refresh-data-source

[devkeydet]

During the dev inner loop, it is common for add new columns to tables, delete columns, etc. It would be great to have a convenient command in pac that goes back to my data source(s) and regenerates the code. Ideally, I should have control of "all" vs the specific ones I want to regen.

Marc Schweigert (@devkeydet) Here is a temporary PowerShell script refreshes the schemas by reading the databaseReferences object from power.config.json and running pac code add-data-source for each Dataverse table.

# PowerShell Script: refresh-schemas.ps1
# Purpose: Scan power.config.json and refresh Dataverse schemas using pac CLI commands

# Define path to configuration file
# Try multiple possible locations to ensure compatibility
$configPath = Join-Path $PSScriptRoot "..\power.config.json"
if (-Not (Test-Path $configPath)) {
    $configPath = Join-Path (Get-Location) "power.config.json"
}

# Check if configuration file exists
if (-Not (Test-Path $configPath)) {
    Write-Error "Configuration file not found. Please ensure power.config.json exists in the project root or current directory."
    exit 1
}

# Change working directory to project root to ensure pac CLI finds power.config.json
$projectRoot = Split-Path $configPath -Parent
Set-Location $projectRoot
Write-Host "Working directory set to project root: $projectRoot"

# Read and parse JSON configuration
try {
    $configContent = Get-Content $configPath -Raw | ConvertFrom-Json
} catch {
    Write-Error "Failed to parse power.config.json: $_"
    exit 1
}

# Extract logicalName properties
$logicalNames = @()

# Handle nested structure under databaseReferences
if ($configContent.databaseReferences) {
    foreach ($dbRef in $configContent.databaseReferences.PSObject.Properties) {
        $dbValue = $dbRef.Value
        if ($dbValue.dataSources) {
            foreach ($source in $dbValue.dataSources.PSObject.Properties) {
                $sourceValue = $source.Value
                if ($sourceValue.logicalName) {
                    $logicalNames += $sourceValue.logicalName
                }
            }
        }
    }
} elseif ($configContent.dataSources) {
    foreach ($source in $configContent.dataSources) {
        if ($source.logicalName) {
            $logicalNames += $source.logicalName
        }
    }
} else {
    Write-Warning "No dataSources found in power.config.json"
}

# Refresh schemas using pac CLI
foreach ($name in $logicalNames) {
    Write-Host "Refreshing schema for logicalName: $name"
    $command = "pac code add-data-source -a dataverse -t $name"
    try {
        Invoke-Expression $command
        Write-Host "Schema refreshed successfully for $name"
    } catch {
        Write-Error ("Failed to refresh schema for {0}: {1}" -f $name, $_)
    }
}

Write-Host "Schema refresh process completed."
