Disable Seeding

Prevent automatic seeding of cron jobs from [TickerFunction] attributes when you want to manage jobs manually.

IgnoreSeedDefinedCronTickers

Disable automatic seeding of cron jobs from attributes.

Method:

TickerQEfCoreOptionBuilder<TTimeTicker, TCronTicker> IgnoreSeedDefinedCronTickers();

Basic Usage

builder.Services.AddTickerQ(options =>
{
    options.AddOperationalStore(efOptions =>
    {
        efOptions.UseTickerQDbContext<TickerQDbContext>(optionsBuilder =>
        {
            optionsBuilder.UseNpgsql(connectionString);
        });
        
        // Disable automatic seeding
        efOptions.IgnoreSeedDefinedCronTickers();
    });
});

When to Disable

Disable automatic seeding when:

• You manage cron jobs manually through the dashboard or API
• Jobs are created programmatically at runtime
• You want full control over job creation
• Jobs are managed by external systems
• You're migrating from automatic to manual job management

What Gets Disabled

IgnoreSeedDefinedCronTickers() only disables:

• Automatic seeding from [TickerFunction] attributes with cron expressions

It does not disable:

• Custom seeding via UseTickerSeeder()
• Manual job creation through managers
• Jobs created at runtime

Example: Manual Job Management

builder.Services.AddTickerQ(options =>
{
    options.AddOperationalStore(efOptions =>
    {
        efOptions.UseTickerQDbContext<TickerQDbContext>(optionsBuilder =>
        {
            optionsBuilder.UseNpgsql(connectionString);
        });
        
        // Disable automatic seeding - manage jobs manually
        efOptions.IgnoreSeedDefinedCronTickers();
    });
});

// Later in your application
public class JobService
{
    private readonly ICronTickerManager<CronTickerEntity> _cronTickerManager;
    
    public async Task SetupJobsAsync()
    {
        // Manually create cron jobs
        await _cronTickerManager.AddAsync(new CronTickerEntity
        {
            Function = "GenerateDailyReport",
            Expression = "0 0 9 * * *",
            Description = "Daily report generation"
        });
    }
}

Combining with Custom Seeding

You can disable automatic seeding but still use custom seeding:

options.AddOperationalStore(efOptions =>
{
    efOptions.UseTickerQDbContext<TickerQDbContext>(optionsBuilder =>
    {
        optionsBuilder.UseNpgsql(connectionString);
    });
    
    // Disable automatic seeding
    efOptions.IgnoreSeedDefinedCronTickers();
    
    // But still use custom seeding
    efOptions.UseTickerSeeder(
        async timeManager =>
        {
            // Custom TimeTicker seeding
            await timeManager.AddAsync(new TimeTickerEntity
            {
                Function = "InitialSetup",
                ExecutionTime = DateTime.UtcNow.AddHours(1)
            });
        },
        async cronManager =>
        {
            // Custom CronTicker seeding
            await cronManager.AddAsync(new CronTickerEntity
            {
                Function = "CustomCronJob",
                Expression = "0 0 */6 * * *" // Every 6 hours
            });
        }
    );
});

Migration Scenario

When migrating from automatic to manual job management:

// Step 1: Disable automatic seeding
options.AddOperationalStore(efOptions =>
{
    efOptions.IgnoreSeedDefinedCronTickers();
});

// Step 2: Existing jobs in database remain unchanged
// Step 3: New jobs must be created manually

// Step 4: Remove [TickerFunction] cron expressions if desired
// (Or keep them for documentation but they won't auto-seed)

Re-enabling Automatic Seeding

To re-enable automatic seeding, simply remove or don't call IgnoreSeedDefinedCronTickers():

options.AddOperationalStore(efOptions =>
{
    efOptions.UseTickerQDbContext<TickerQDbContext>(optionsBuilder =>
    {
        optionsBuilder.UseNpgsql(connectionString);
    });
    // Don't call IgnoreSeedDefinedCronTickers()
    // Automatic seeding is enabled by default
});

Impact on Existing Jobs

Disabling automatic seeding does not:

• Delete existing jobs from the database
• Modify existing jobs
• Prevent manual job creation
• Affect jobs created via custom seeding

Existing jobs continue to run normally.

Best Practices

1. Document your decision - Note why automatic seeding is disabled
2. Use custom seeding - For initial setup jobs when disabling automatic seeding
3. Version control - Track which jobs should exist if managing manually
4. Dashboard management - Use the dashboard to create and manage jobs visually
5. API management - Create jobs programmatically via managers when needed
