Frontend

UI/UX Design Plan

Validations to handle

  • PDF Proposal Upload must be under 8MB (soft limit)

Server-Client Behavior Agreeement

  • When new user uses OAuth to register, the token validation (POST /api/auth/) will return with, 
    {
    error_code: 901,
    message: "User must be created",
    url: "/api/user/",
    method: "POST"
}
HTTP_CODE: 404
    Initiate a form on the frontend to collect user metadata i.e. role, access, etc. and create a user using the given URL and METHOD. Then, send the same token to the token validation (POST /api/auth/) endpoint.

Tailored API Endpoints

NOTE: Specify API endpoint requirements under Requested Endpoint Requirements here: https://docs.google.com/document/d/1BuqWLfZSf08XkSRbJId3BAIZCT0FmTrVLlO-6XchuT4/edit?usp=sharing

GET api/user[?field=value&...]

  • Resonds with all user collections
  • Now supports filters! Multiple filters may be used
  • The following fields can be used for fitering by being passed as GET query parameters,
    • ?email=abc@gmail.com
    • ?first_name=Adam : Case-sensitive for now
    • ?last_name=Adam : Case-sensitive for now
    • ?role=student : One of faculty, student

GET api/proposal/user/[userId]

  • userId is the _id field value of the user
  • Responds with all projects belonging to the specified user, like so 
    {
  as_supervisor: [ <proposal collections with the user as a supervisor>... ],
  as_member: 	[ <proposal collections with the user as a member>... ],
  as_leader: 	[ <propoal collections with the user as a leader>... ]
}

GET api/project/user/[userId]

  • userId is the _id field value of the user
  • Responds with all projects belonging to the specified user, like so 
    {
  as_supervisor: [ <project collections with the user as a supervisor>... ],
  as_member: 	[ <project collections with the user as a member>... ],
  as_leader: 	[ <project collections with the user as a leader>... ]
}

GET api/resource-group?available=[anything]

  • [anything] is an arbitrary value. This is parsed for GET syntactic convenience - value ignored
  • The key available is of importance
  • Responds with all resource groups having allocatable resources along with an additional field avl_qty to denote number of resource instances of the group that can be allotted, like so
[
 {
   <all-resource-group fields> : <field-values>,
   .
   .
   avl_qty: 2
 }
 .
 .
]

PUT api/resource-assignment

With request body,

{
  rsrc_mgr_id = '<manager_id>',
  project_id = '<project_id>',
  rsrc_grp_id = '<resource_group_id>',
  qty = 1
}

  • The ids correspond the the _id fields of the respective resources

  • qty refers to the number of assignments of that resource group desired at the end of this transaction. This can be lower or higher than the current number of allocations

  • Responds with the type of changes made:

    • If current assignments are same as qty,
    {"total_qty":2,"assigned_qty":0,"message":"No resource assignments made"}
    • If new assignments were made:
    {"total_qty":4,"assigned_qty":1,"project_id":"62a4e23619d791faaf76e19a","resource_group_id":"628abd6b4bc531d7264a0aaa","message":"Resource deallocations made"}
    • If assignments were removed:
    {"total_qty":4,"assigned_qty":1,"project_id":"62a4e23619d791faaf76e19a","resource_group_id":"628abd6b4bc531d7264a0aaa","message":"Resource deallocations made"}

    Numbers above are samples only

NOTE: If the available qty CANNOT satisfy the request, maximum possible qty is assigned. Eg: If only 3 resources can be allocated, and the request is made for 4, then 3 items are allocated and the response indicated the same through assigned_qty field

GET api/resource-assignment/project/[projectId]

  • [projectId] is the project id of the project whose resource allocations are being requested
  • Responds with all resource allocation records for the project resources along, with three additional fields:
    • _id denoting the ID of the resource group
    • assigned_qty to denote number of resource instances of the group already allotted
    • resource_data containing specific resource details, along with the ID of its resource group
[
 {
   _id: <resource-group id>
   <all-resource-allocation fields> : <field-values>,
   .
   .
   resource_data : [ { <all resource fields> : <field-values> } ]
   assigned_qty: 2
 }
 .
 .
]
