Description

This change ensures that parallel reservations in FBS are displayed as a single reservation in the UI:

The reservationId attribute for ListType has been replaced by a reservationIds attribute
A new hook for retrieving reservation groups has been implemented. This supersedes the default useGetReservationsV2(). Instead of returning individual reservations it returns reservation groups which contain an array of reservation ids. Single reservations will have a single entry, parallel reservations will have multiple. The return value is mapped to the current ListType and ReservationType types.
In general passing around strings as different forms of identifiers have been replaced by passing around business objects. As a mininum ListType but preferably ReservationType or LoanType where applicable.
Components which previously took nullable faust (FBS) and identifier (Publizon) props now take a single ListType item prop
Higher-order components fetchDigitalMaterial() and fetchMaterial() now work with item props
States which previously used strings for ids, now use business objects

This change has lead to a number of related changes along the way:

To have a stable approach for generating string ids for business objects I have created itemId(), loanId() and reservationId() functions. They can be used for key props and potentially id attributes.
Test cases and fixtures have been updated with parallel reservations
I have removed it.only() from a few test cases to be able to run all tests locally. I have skip'ed or fixed other cases in the same test which is now running.
Helpers related to modals have been moved from helpers/general to helpers/modal-helpers
Construction of modal id strings are delegated to functions related to the individual modal component which take relevant domain objects as arguments e.g. deleteReservationModalId(ReservationType)
A few components have been updated to use the new domain hooks for loans and reservations
Equality checks for business objects instead of primitives means that we have to use isEqual() from Lodash and useDeepCompareEffect() from react-use
In an attempt to make Cypress tests less flaky I have added aliases and wait() in some tests. This is especially relevant for test cases which rely on other e.g. get the first list of reverations which can either be ready, physical or digital depending on what loads first.
I merged in Get rid of node in docker and adjust task cmds #577 to ease my development proces. We should consider if the comments there should be considered before merging this or these changes should be pulled from this PR.

Additional comments or questions

I have tried to add comments throughout the PR to explain what is going on
I tried to enable Cypress Cloud during this PR (0510d98). I disabled it again to avoid getting to much in. You can see it in action in this PR.
Codecov fails even though it should not. Sigh.

All this deletion is a result of using useReservations() and business objects leading to much fewer states and effects.

As I see it i have identified a bug here. The reservation sent to FBS does not actually use the updated value. That should be handled in a separate issue though.

Great. Did you already create a task for it?

This is also another key point of the PR: Reservations are grouped by transaction id to identify and create parallel reservations.

Makes sense. Did you create a type for the id?

src/core/utils/useGetReservationGroups.ts

This reverts commit 2e050fe.

There is no need for the extra states and we get the expected return type by default.

This is necessary for handling parallel reservations

This ensures that it matches the reservation id used in the the reservation list with physical detail modal story. If not then no modal will be opened by default. This kind of defeats the purpose of the story.

Now that we are moving to using business objects as dependencies they fail the standard equality check of useEffect. We have decided to use useDeepEffect() to address this so lets do so.

There is no reason to include test in the test name. It is implicit.

Even though this test does not test digital reservations having a stub which returns an empty list means that requests should resolve and hopefully make our tests less flaky.

Add aliases to intercepted requests and wait for these to finish before proceeding. This should make our tests less flaky.

This should allow us to to verify that requests with the expected payloads are sent.

It does work in that multiple reservation updates are sent but not with the expected payload. That will have to be fixed separately.

With the added support for parallel reservations the singular value should not be used anymore. Remove all references to it: - Where it is used for modal ids: Replace it with modal specific helpers - Where it is no longer needed: Remove it

This helps with testing. The current mock will always succeed.

For whatever reason the test hangs when trying to open the modal for a digital loan. This occurs locally and in CI when running in Cypress. Opening up the same modal seems to work fine normally. Disable the test so we can move on.

Apparently this is rendered now so lets update the test accordingly.

Use isEqual() for deep object equality. The instances might not be the same even if the values are equal.

MaterialIds is not a telling name when it is actually materials (or reservations) we are passing around.

This ensures consistency.

This makes it easier to map to other places where we also list facets

We need to use this for parallel reservations. As these reservations consist of multiple materials we do not have a single manifestation to show data from. Instead we take one of the reservations and look up the best representation of the owner work corresponding to the faust id for the reservation. To make things consistent we introduce a fragment which has the same signature for direct manifestation lookups used for normal reservations and best representation lookups used for parallel reservations.

Support for DK5 and year facets have been added. We do not use them at the moment but we add support for texts for them for good measure.

Use our new query to retrieve data from the best representation of the owner work of one of the faust ids in our parallel reservation. In general our parallel reservation data structure only contain a single faust id (from the first reservation in the group). This may seem liked a problem but based on the assumption that any faust id in the group should return the same owner work which should return the same best representation this should actually be OK. Since parallel reservations may appear in different locations throughout the app handling is added to the fetchMaterial() higher order component. We can the utilize the fact that both hooks for retrieving material data use the same fragment. Expand the reservation list Cypress test to show that data fetching for parallel reservations works.

Our current graphQL mocking does not seem to support varying responses by operation. This means we cannot provide different responses when looking upmaterial data for singular and parallel reservations. Update with singular use cases to use best representation work fixture where possibe. When tests mix parallel and normal reservations we revert to only using normal reservations.
