将pickBy和mapValues从lodash转换为函数

Question

我正在尝试将此使用pickBy和mapValues的函数从lodash转换为不使用lodash的函数。

import mapValues from 'lodash/mapValues';
import pickBy from 'lodash/pickBy';

    function clinicsWithInvitations(upcomingClinics) {
      const upClinics = upcomingClinics.clinics;
      const upInvitations = upcomingClinics.invitations;

      const getInvitations = id => pickBy(upInvitations, inv => inv.clinicId === id);
      const mergeInvitations = (clinic, clinicId) => ({
        ...clinic,
        invitations: getInvitations(clinicId),
      });

      return mapValues(upClinics, mergeInvitations);
    }

我尝试了这个，但是没有用

function clinicsWithInvitations(upcomingClinics) {
  const upClinics = upcomingClinics.clinics;
  const upInvitations = upcomingClinics.invitations;

  const getInvitations = clinicId =>
    Object.keys(upInvitations).reduce((acc, invId) => {
      const inv = upInvitations[invId];
      return inv.clinicId === clinicId ? { ...acc, [inv.clinicId]: inv } : acc;
    }, {});

  const mergeInvitations = (acc, clinicId) => ({
    ...acc,
    [clinicId]: {
      ...upClinics[clinicId],
      invitations: getInvitations(clinicId),
    },
  });
  return Object.keys(upClinics).reduce(mergeInvitations, {});
}

我想要做的是将两个对象组合成一个对象，我正在尝试将诊疗所与邀请相关联，同时考虑到clinicId ，因此我clinicId ：

const upcomingClinics = {
  "clinics": {
    "a0CW000000271LuMAI": {
      "id": "a0CW000000271LuMAI",
      "contact": {
        "name": null,
        "phone": null,
        "email": null
      },
      "shifts": {
        "teamLeads": 1,
        "healthTechs": 1
      }
    },
    "a0CW00000026gikMAA": {
      "id": "a0CW00000026gikMAA",
      "contact": {
        "name": null,
        "phone": null,
        "email": null
      },
      "shifts": {
        "teamLeads": 1,
        "healthTechs": 4
      }
    }
  },
  "invitations": {
    "56392": {
      "id": "56392",
      "clinicId": "a0CW00000026gikMAA"
    },
    "56393": {
      "id": "56393",
      "clinicId": "a0CW00000026gikMAA"
    },
    "56402": {
      "id": "56402",
      "clinicId": "a0CW00000026gikMAA"
    },
    "56427": {
      "id": "56427",
      "clinicId": "a0CW000000271LuMAI"
    },
    "56428": {
      "id": "56428",
      "clinicId": "a0CW000000271LuMAI"
    }
  }
}

这是所需的输出，但不会引起任何突变。

const upcomingClinics = {
  "clinics": {
    "a0CW000000271LuMAI": {
      "id": "a0CW000000271LuMAI",
      "contact": {
        "name": null,
        "phone": null,
        "email": null
      },
      "shifts": {
        "teamLeads": 1,
        "healthTechs": 1
      }
      "invitations": {
        "56427": {
          "id": "56427",
          "clinicId": "a0CW000000271LuMAI"
        },
        "56428": {
          "id": "56428",
          "clinicId": "a0CW000000271LuMAI"
        }
      }
    },
    "a0CW00000026gikMAA": {
      "id": "a0CW00000026gikMAA",
      "contact": {
        "name": null,
        "phone": null,
        "email": null
      },
      "shifts": {
        "teamLeads": 1,
        "healthTechs": 4
      }
      "invitations": {
        "56392": {
          "id": "56392",
          "clinicId": "a0CW00000026gikMAA"
        },
        "56393": {
          "id": "56393",
          "clinicId": "a0CW00000026gikMAA"
        },
        "56402": {
          "id": "56402",
          "clinicId": "a0CW00000026gikMAA"
        },
      }
    }
  },
}

Answer 1

您当前的尝试看起来确实很接近，但是我认为您的打字错误很小。 这个：

const getInvitations = clinicId =>
  Object.keys(upInvitations).reduce((acc, invId) => {
    const inv = upInvitations[invId];
    return inv.clinicId === clinicId ? { ...acc, [inv.clinicId]: inv } : acc;
  }, {});

...使用[inv.clinicId]作为键时，如果invitations属性将由邀请ID invId为您想要的invId ，则：

const getInvitations = clinicId =>
  Object.keys(upInvitations).reduce((acc, invId) => {
    const inv = upInvitations[invId];
    return inv.clinicId === clinicId ? { ...acc, [invId]: inv } : acc;
  }, {});

Answer 2

接下来，首先使用climateId作为键创建所有邀请的地图。

然后是对所有诊所进行合并的简单循环

 function clinicsWithInvitations(upcomingClinics) { const invitesMap = Object.entries(upcomingClinics.invitations).reduce((a, [id, invite]) => { const clinic = a.get(invite.clinicId) || {} clinic[id] = { ...invite}; return a.set(invite.clinicId, clinic) }, new Map) const clinics = { ...upcomingClinics.clinics}; Object.keys(clinics).forEach(k => clinics[k].inivitations = invitesMap.get(k) || {}); return {clinics: clinics}; } console.log(clinicsWithInvitations(upcomingClinics)) 

 .as-console-wrapper { max-height: 100%!important; } 

 <script> const upcomingClinics = { "clinics": { "a0CW000000271LuMAI": { "id": "a0CW000000271LuMAI", "contact": { "name": null, "phone": null, "email": null }, "shifts": { "teamLeads": 1, "healthTechs": 1 } }, "a0CW00000026gikMAA": { "id": "a0CW00000026gikMAA", "contact": { "name": null, "phone": null, "email": null }, "shifts": { "teamLeads": 1, "healthTechs": 4 } } }, "invitations": { "56392": { "id": "56392", "clinicId": "a0CW00000026gikMAA" }, "56393": { "id": "56393", "clinicId": "a0CW00000026gikMAA" }, "56402": { "id": "56402", "clinicId": "a0CW00000026gikMAA" }, "56427": { "id": "56427", "clinicId": "a0CW000000271LuMAI" }, "56428": { "id": "56428", "clinicId": "a0CW000000271LuMAI" } } } </script>
