It is required for a number of modules (both BE and FE) to be able to check if a patron should be blocked from borrowing, renewing and/or requesting items and why. mod-circulation should check for these blocks every time one of these actions is performed. Also, we need to provide an endpoint (at least for UI modules, see UIU-1273) for checking patron block conditions. Each of these condition checks has a dependency on functionality implemented in various modules:

Approach 1 (mod-circulation)

...

No new dependencies are required in mod-circulation for Approach 1.

/patron-block-condition

/patron-block-limits?query=(patronGroupId=={patronGroupId})

/accounts?query=(userId=={patronId} AND status=="Open")

/calendar/periods

Approach 2 (new module; pub-sub)

Publishing/subscriptions configuration

{
  "patronId": string,
  "balance": numeric
}

Example:

{
  "patronId": "1785d668-831e-11ea-bc55-0242ac130003",
  "balance": -15
}

{
  "patronId": string,
  "loanId": string,
  "dueDate": string
}

{
  "patronId": string,
  "loanId": string
}

{
  "patronId": string,
  "loanId": string
}

{
  "patronId": string,
  "loanId": string,
  "dueDate": string,
  "recall": boolean
}
