Issue #124: Project Base - Erstellen eines Projekts

Summary

Issue #124 requested the implementation of project creation functionality with the following required fields: - customer - start at - ends at - name - description

Status: ✅ COMPLETE - This feature has been fully implemented and is operational.

What Was Implemented

1. Database Schema

File: database/migrations/009_create_projects_table.sql

The projects table includes all required fields and more:

CREATE TABLE projects (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  service_provider_id UUID NOT NULL REFERENCES service_providers(id) ON DELETE CASCADE,

  -- Required fields from issue #124
  name VARCHAR(255) NOT NULL,
  description TEXT,
  customer_id UUID NOT NULL REFERENCES customers(id) ON DELETE CASCADE,
  start_at TIMESTAMP WITH TIME ZONE NOT NULL,
  ends_at TIMESTAMP WITH TIME ZONE,

  -- Additional fields for full project management
  project_number VARCHAR(50),
  billing_frequency project_billing_frequency DEFAULT 'monthly',
  currency VARCHAR(3) DEFAULT 'EUR',
  last_invoiced_at TIMESTAMP WITH TIME ZONE,
  next_billing_date TIMESTAMP WITH TIME ZONE,
  default_hourly_rate DECIMAL(10,2),
  status project_status DEFAULT 'planning',
  auto_group_by_issue BOOLEAN DEFAULT true,
  exclude_merge_commits BOOLEAN DEFAULT true,
  exclude_commit_patterns TEXT,
  tags JSONB,
  custom_fields JSONB,
  created_at TIMESTAMP WITH TIME ZONE DEFAULT now(),
  updated_at TIMESTAMP WITH TIME ZONE DEFAULT now()
);

Related Tables: - database/migrations/010_create_project_customers.sql - Many-to-many relationship between projects and customers - database/migrations/011_create_work_units.sql - Work units linked to projects - database/migrations/014_add_project_to_documents.sql - Link invoices to projects - database/migrations/015_add_currency_to_projects.sql - Currency support for projects

2. Schema Validation

File: schemas/src/ProjectSchema.ts

Comprehensive Zod schema with all required fields:

export const ProjectSchema = z.object({
  id: z.uuid().optional(),
  service_provider_id: z.uuid({ error: "service_provider_required" }),

  // Required fields from issue #124
  name: z.string({ error: "project_name_required" })
    .min(1, { error: "project_name_required" })
    .max(255, { error: "project_name_too_long" }),
  description: z.string().nullable().optional(),
  customer_id: z.uuid({ error: "customer_required" }),
  start_at: z.coerce.date({ error: "invalid_start_date" }),
  ends_at: z.coerce.date({ error: "invalid_end_date" }).nullable().optional(),

  // Additional project management fields
  billing_frequency: BillingFrequencySchema.default("monthly"),
  currency: CurrencyCodeSchema.default("EUR"),
  default_hourly_rate: z.number().positive().nullable().optional(),
  status: ProjectStatusSchema.default("planning"),
  // ... more fields
});

Request/Response Schemas: - CreateProjectSchema - For POST requests - UpdateProjectSchema - For PUT requests (partial updates) - ProjectResponseSchema - For API responses - ProjectListResponseSchema - For paginated lists

Type Exports:

export type Project = z.infer<typeof ProjectSchema>;
export type CreateProject = z.infer<typeof CreateProjectSchema>;
export type UpdateProject = z.infer<typeof UpdateProjectSchema>;

3. Backend API

File: apps/api/src/routes/projects.ts

Full REST API with OpenAPI documentation:

Core CRUD Operations

// Query parameters
{
  page?: number,
  per_page?: number,
  status?: "planning" | "active" | "on_hold" | "completed" | "cancelled",
  customer_id?: string
}

// Response
{
  data: Project[],
  total: number,
  page: number,
  per_page: number
}

POST /projects - Create new project

Project Detail Pages

Files: - apps/web/pages/member/feature/project/[id]/index.vue - Project overview - apps/web/pages/member/feature/project/[id]/edit.vue - Edit project - apps/web/pages/member/feature/project/[id]/work-units.vue - Work units management

Project Creation Page

File: apps/web/pages/member/feature/project/new.vue

Simple wrapper around ProjectForm component for creating new projects.

5. Composables & State Management

useProject Composable

File: apps/web/composables/useProject.ts

Provides all project-related functionality:

export const useProject = () => {
  // Core CRUD operations
  const getProjects = async (page = 0, perPage = 50, filters = {}) => { ... }
  const getProject = async (id: string) => { ... }
  const createProject = async (data: CreateProject) => { ... }
  const updateProject = async (id: string, data: UpdateProject) => { ... }
  const deleteProject = async (id: string) => { ... }

  // Advanced operations
  const getProjectCustomers = async (id: string) => { ... }
  const getProjectRepositories = async (id: string) => { ... }
  const generateInvoiceFromWorkUnits = async (id: string, data) => { ... }

  return {
    getProjects,
    getProject,
    createProject,
    updateProject,
    deleteProject,
    getProjectCustomers,
    getProjectRepositories,
    generateInvoiceFromWorkUnits
  }
}

Project Status Machine

File: apps/web/composables/useProjectStatusMachine.ts

XState-based state machine for project lifecycle management.

6. Navigation & Integration

File: apps/web/components/navigation/MemberSidebar.vue

Projects have their own section in the member sidebar with icon and proper routing.

Invoice Integration

Projects are fully integrated with the invoicing system: - Projects can be selected when creating invoices - Work units are linked to projects - Automatic invoice generation from project work units - Project-based billing frequencies

7. Internationalization

Files: - apps/web/i18n/locales/en.json - apps/web/i18n/locales/de.json

All project-related labels are internationalized:

{
  "label": {
    "projects": "Projects",
    "project_name": "Project Name",
    "customer": "Customer",
    "start_date": "Start Date",
    "end_date": "End Date",
    "description": "Description"
  },
  "project": {
    "status": {
      "planning": "Planning",
      "active": "Active",
      "on_hold": "On Hold",
      "completed": "Completed",
      "cancelled": "Cancelled"
    },
    "billing_frequency": {
      "weekly": "Weekly",
      "monthly": "Monthly",
      "quarterly": "Quarterly"
    }
  }
}

8. Testing

Data Flow

1. Project Creation

  1. User fills project form with required fields:
  2. name (string, required)
  3. customer (selected from dropdown, required)
  4. start at (date picker, required)
  5. ends at (date picker, optional)

  6. description (textarea, optional)

  7. Frontend validates with CreateProjectSchema

  8. API receives validated data
  9. API adds service_provider_id from authenticated user
  10. Database stores project with all fields
  11. Returns created project to frontend
  12. User redirected to project detail page

2. Project Management

  1. List View: Paginated list with search and filters
  2. Detail View: Complete project information
  3. Edit Form: Update any project fields
  4. Work Units: Track time and tasks for project
  5. Invoice Generation: Create invoices from work units

3. Integration Points

  • Customers: Projects must have at least one customer
  • Work Units: Time tracking linked to projects
  • Invoices: Generated from project work units
  • Git Repositories: Source code tracking per project
