# Week 08 - Wrap up

## 1 Add Status filter in fetch tasks of a project.
We have already implemented endpoint to return list of tasks of a project
`api/mobile/v1/projects/{id}/tasks`

now implement the following:
- If no status passed as query string param in url, then return all list of tasks
- If status passed ex: `api/mobile/v1/projects/{id}/tasks?status=to_do`:
then return only the tasks that its status is `to_do`, and so on for other statuses.


## 2 Implement Endpoints for Dashboard/Statistics data

### Implement one endpoint to return statistics data for a client/Freelancer
endpoint `api/mobile/v1/GetMyStatistics`

Data in the Response shoule be like below:

{
   Projects:{
     Total:7,
     Available:2,
     Closed:5
   },
   Tasks:{
    Total:21,
    ToDo:'23%',
    InReview:"Y%"
    InProgress:"44%".
    Done:"X%"
    }
   
}

NOTE: We will return projectt status `Available` and `Closed` instead of `Pending`, 'In Progress', `Done`

## 3 Re-implement Skills for a freelancer
We implemented skills as string property in the Freelancer user type, however, we need to seperate skills as list:
### Step 1, Remove Skills string from freelancer entity
- this require to review all the code and remove any usage for this proprty
- Remove skills from DTOs like, register DTO, during register we don't need from the user to upload his skills.
### Step 2, Define new Entity Called `Skill`
Columns:
- Id: Pk
- UserId: FK of freelancer
- Name: name of the skill

Implement the relationship betwee freelancer and Skill by Data annotation or fluent API, each Freelancer have many skills. (1-m relattionship)
Do the migration to create new table called `Skills`.

### Implement new endpoints to Add or Remove Skills
1. `api/mobile/v1/users/{id}/skills` POST to for adding
2. `api/mobile/v1/users/{id}/skills` REMOVE to for removing skill

Hints:
- Validate the requestor user id is the same as passed in the URL(because another user should be able to remove or add skill for other user)

## 4 (Bonus) Modify endpoints of projects filter
Freelancer have diffetent options to filter on projects in the feed as below:

Propose, design and implement this by yourself :).

## 5(Bonus) `Like` feature
Lets implement a "like" feature for projects of clients, so each user `Client` or `Freelancer` is able to add like to the project publiched by a client. each user should be able to like the project once, remove it. also we should return number of likes for a project and in the returned projects list.

### Step 1, Entity and Database Migration
Create new Entity/table called `ProjectLikes` with following columns:
- Id: pk of the table.
- ProjectId: fk of projects, represent the project that have this like
- UserId: fk, represent the user who like this project
- CreatedAt: datetime of the like action.

**Hint**: add unique constraints for `ProjectId` + `UserId`, read about this if you don't know about it.

Migrate new changes, new table should be created in the database.
### Step 2, Implement endpoint for like/unlike
Implement new endpoint
`/api/mobile/v1/projects/{pid}/like`, Http verb is POST
Send in the body action (`like`,`unlike`)
**Hints**:
- you can read UserId from current authorized user who is making the request.
- User/Actor allowed to be freelancer/client
- publisher could like his project normally.
- when action is `like`, validate and check that the user is never `like` this project before.(using unique constraint + logic validation)

### Step 3, Return number of likes for each project
Go back to any endpoint that return projects details, include number of likes propery to be returned for the front-end
example: list of projects that is returned to the front should have new property `likes` as count.
