問題描述

我在下面有一個這種結構的火力基地

我的 Firestore 數據庫的結構

它有兩個用戶，即教會管理員和普通教會用戶

對於教會管理員，這是注冊新教會的代碼

public void onBoardChurchDetails(String church_name, String church_addr, String church_email, String church_leadName, String churchPhone, String church_icon, String churchDescr, String church_regStat, final String uid) {
    if (networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        rhemaCollRef = rChurchFireStore.collection("rhema_churches");
        rhemaHiveChurchSubClass = getRhemaHiveChurchSubClass();

        if (rhemaHiveChurchSubClass.checkChurchEmptyParams(church_icon, church_name, church_addr, churchPhone, church_email, church_leadName, churchDescr, church_regStat,uid) == 1) {

            rhemaHiveChurchModelClass = getChurchModelClass(church_name, church_addr, church_email, church_leadName, churchPhone, church_icon, churchDescr, church_regStat,uid);

            rhemaCollRef.document(church_name).set(rhemaHiveChurchModelClass).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {

                    if (task.isSuccessful()) {
                        try {
                            getAuto().getToast(c, " Congratulations you Just Registered a new Church", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                            intent  = new Intent(c, RhemaHiveChurchPortal.class);
                            bundle.putString("church_id", uid);

                            intent.putExtras(bundle);
                            startActivity(intent);
                            clearChurchDetails();
                        }
                        catch(NullPointerException np){
                            getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + np.getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                        }
                    } else {
                        getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + task.getException().getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                        startActivity(getAuto().newActivityStarter(c, RhemaHiveChurchPortal.class));
                    }
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                }
            });


        } else {

            getAuto().getToast(c, "Oops Seems we are missing out some data here", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();

        }

    } else {
        getAuto().getToast(c, "Oops Seems No Internet Service is connected", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }
}

對於用戶注冊，我有

 public void onBoardUserWithoutSocial(String fName, String lName, String gender, String userType, String dob, String regStat, String imgPath, String userEmail, String phone , String about, final String churchName, String branchName, String addr, String city, String country, String postalCode, final String uid) {
    if (networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        fstore = getFstore();
    fiReference = fstore.collection("rhema_churches");
    rhemaHiveUserSubClass = getRhemaHiveUserSubClass();

        if (rhemaHiveUserSubClass.checkEmptyParam(fName, lName, branchName, churchName, addr, country, city, dob, gender, postalCode, regStat, phone,  userType,imgPath,userEmail,about,uid) == 1) {
            rhemaHiveUserModelClass = getUserModelClass(fName,lName,gender,userType,dob,regStat, imgPath,userEmail,phone,about,churchName,branchName,addr,city,country,postalCode,uid);
            fiReference.document(churchName).collection("members_data").document(getFullName(fName,lName)).set(rhemaHiveUserModelClass).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if(task.isSuccessful()){
                        try{
                        getAuto().getToast(c, "Congratulation You've onboarded sucessfully..",RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                            bundle.putString("user_id", uid);
                            bundle.putString("user_church",churchName);

                            intent.putExtras(bundle);
                        startActivity(intent);
                        clearUserDetails();
                        }
                        catch(NullPointerException np){
                            getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + np.getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                        }

                    }
                    else{
                        getAuto().getToast(c,RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + task.getException().getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();

                    }
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                }
            });

        } else {
            getAuto().getToast(c, "Oops ! !..Seems we are missing out some of your details", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
        }
    }
    else{
        getAuto().getToast(c, "Oops ! !..Seems you need to put on your data", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }
}

成功注冊后，我希望普通用戶能夠在使用 Facebook、Twitter 或 google 等任何提供商進行身份驗證后登錄，他的門戶應該使用 uuid 和電話號碼的組合檢索他的個性化門戶

要檢索教會資料，請參閱下面的代碼

public void retreiveChurchDetails(String id) throws NullPointerException{
    if(networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
    FirebaseFirestore fS = getFStore();
    rhemaCollRef = fS.collection("rhema_churches");
    rhemaCollRef.whereEqualTo("church_uid", id ).get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
        @Override
        public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
                for(DocumentSnapshot documentSnapshot  : queryDocumentSnapshots.getDocuments()){
                    church_name = documentSnapshot.getString("church_name");
                    church_email = documentSnapshot.getString("church_email");
                    church_phone = documentSnapshot.getString("church_phone");
                    church_pix_link = documentSnapshot.getString("church_pix");
                    getTextView(R.id.church_retr_name).setText(church_name);
                    getTextView(R.id.church_retr_email).setText(church_email);
                    getTextView(R.id.church_retr_phone).setText(church_phone);
                    ld_wt_gl(c,church_pix_link,44,44,getImg(R.id.church_retr_logg));

                }
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            getAuto().getToast(c,RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
        }
    });
    }

    else{
        getAuto().getToast(c, "Oops ! !..Seems we need an internet connection for this", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }
}

我的問題是我如何完全了解要獲取用戶數據必須遵循以下結構來檢索用戶詳細信息

rhema_churches => Church_name(需要確定如何獲得這個) => document => members_data => user_data

請參考上面附上的數據庫結構

請幫助我..

看看我嘗試了什么

 public void retrUserDet(final String uid, String church_name) throws NullPointerException{
    if(networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        FirebaseFirestore fS = getFStore();
        rhemaCollRef = fS.collection("rhema_churches");
        rhemaCollRef.document(church_name).collection("members_data").whereEqualTo("user_uid",uid).get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
            @Override
            public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
                if(!queryDocumentSnapshots.getDocuments().isEmpty()){
                    for(DocumentSnapshot doc : queryDocumentSnapshots.getDocuments()){
                        user_email = doc.getString("user_email");
                        user_name = doc.getString("user_fName") + doc.getString("user_lName");
                        user_phone = doc.getString("user_phone");
                        user_pix_link = doc.getString("user_pix");
                        getTex(R.id.user_retr_email).setText(user_email);
                        getTex(R.id.user_retr_name).setText(user_name);
                        getTex(R.id.user_retr_phone).setText(user_phone);
                        ld_wt_gl(c,user_pix_link,44,44,getImg(R.id.user_retr_logg));

                    }
                }

            }
        });

    }
}

上面的這個方法需要兩個參數來執行它的查詢，即uid和churchName

這是我嘗試檢索教堂名稱的方法，但它不起作用

  public String retrChurchName(String uid){
    if (networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        rhemaCollRef = rChurchFireStore.collection("rhema_churches");
        //rhemaCollRef.
        rhemaCollRef.whereEqualTo("uid",uid).get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
            @Override
            public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
                for(DocumentSnapshot documentSnapshot : queryDocumentSnapshots.getDocuments()
                )
                {
                    if(documentSnapshot.exists()){
                        churchName = documentSnapshot.getString("church_name");
                    }

                    else{
                        getAuto().getToast(c,"Document doesnt exist", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();

                    }
                }
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                getAuto().getToast(c,RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
            }
        });

        return churchName;

    }

    else{
        getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + networkInfo.getExtraInfo(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }

    return "";
}

謝謝 ！

所以我能夠解決我的問題並且我的代碼運行良好..感謝 Alex Mamo

我必須做的第一件事是為教會和用戶重新構建我的入職代碼

對於教會我有

  public void onBoardChurchDetails(String church_name, String church_addr, String church_email, String church_leadName, String churchPhone, String church_icon, String churchDescr, String church_regStat, final String uid, String userType) {
    if (networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        rhemaCollRef = rChurchFireStore.collection("rhema_churches");
        rhemaHiveChurchSubClass = getRhemaHiveChurchSubClass();

        if (rhemaHiveChurchSubClass.checkChurchEmptyParams(church_icon, church_name, church_addr, churchPhone, church_email, church_leadName, churchDescr, church_regStat, uid, userType) == 1) {

            rhemaHiveChurchModelClass = getChurchModelClass(church_name, church_addr, church_email, church_leadName, churchPhone, church_icon, churchDescr, church_regStat, uid, userType);

            rhemaCollRef.document(uid).set(rhemaHiveChurchModelClass).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {

                    if (task.isSuccessful()) {
                        try {
                            getAuto().getToast(c, " Congratulations you Just Registered a new Church", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();

                            bundle.putString("church_id", uid);

                            intent.putExtras(bundle);
                            startActivity(intent);
                            //clearChurchDetails();
                        } catch (NullPointerException np) {
                            getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + np.getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                        }
                    } else {
                        getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + task.getException().getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                        startActivity(getAuto().newActivityStarter(c, RhemaHiveChurchPortal.class));
                    }
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                }
            });


        } else {

            getAuto().getToast(c, "Oops Seems we are missing out some data here", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();

        }

    } else {
        getAuto().getToast(c, "Oops Seems No Internet Service is connected", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }
}

對於用戶入職，我有

public void onBoardUserWithoutSocial(String fName, String lName, String gender, String userType, String dob, String regStat, String imgPath, String userEmail, String phone , String about, final String churchName, String branchName, String addr, String city, String country, String postalCode, final String uid) {
    if (networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        fstore = getFstore();
    fiReference = fstore.collection("rhema_churches");
    rhemaHiveUserSubClass = getRhemaHiveUserSubClass();

        if (rhemaHiveUserSubClass.checkEmptyParam(fName, lName, branchName, churchName, addr, country, city, dob, gender, postalCode, regStat, phone,  userType,imgPath,userEmail,about,uid) == 1) {
            rhemaHiveUserModelClass = getUserModelClass(fName,lName,gender,userType,dob,regStat, imgPath,userEmail,phone,about,churchName,branchName,addr,city,country,postalCode,uid);
            fiReference.document(uid).set(rhemaHiveUserModelClass).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if(task.isSuccessful()){
                        try{
                        getAuto().getToast(c, "Congratulation You've onboarded sucessfully..",RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                            bundle.putString("user_id", uid);
                            bundle.putString("user_church",churchName);

                            intent.putExtras(bundle);
                        startActivity(intent);
                        clearUserDetails();
                        }
                        catch(NullPointerException np){
                            getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + np.getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                        }

                    }
                    else{
                        getAuto().getToast(c,RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + task.getException().getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();

                    }
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(),RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
                }
            });

        } else {
            getAuto().getToast(c, "Oops ! !..Seems we are missing out some of your details", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
        }

    }




    else{
        getAuto().getToast(c, "Oops ! !..Seems you need to put on your data", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }
}

因此，而不是在另一個集合中包含一個集合。我只是將一個集合作為 rhema_churches，然后為每種類型的用戶設置了一個 ID。

看下面的結構

新的數據庫結構

使用這種結構，登錄多個提供程序變得很困難，因為您使用的每個提供程序都被記錄為易於檢索的文檔 ID

這就是 User 和 Church 的新查詢現在的樣子

對於教堂查詢，我們有

 public void retreiveChurchDetails(String id) throws NullPointerException {
    if (networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        FirebaseFirestore fS = getFStore();
        rhemaCollRef = fS.collection("rhema_churches");
        rhemaCollRef.whereEqualTo("church_uid", id).get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
            @Override
            public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
                for (DocumentSnapshot documentSnapshot : queryDocumentSnapshots.getDocuments()) {
                    church_name = documentSnapshot.getString("church_name");
                    church_email = documentSnapshot.getString("church_email");
                    church_phone = documentSnapshot.getString("church_phone");
                    church_pix_link = documentSnapshot.getString("church_pix");
                    getTextView(R.id.church_retr_name).setText(church_name);
                    getTextView(R.id.church_retr_email).setText(church_email);
                    getTextView(R.id.church_retr_phone).setText(church_phone);
                    ld_wt_gl(c, church_pix_link, 88, 88, getImg(R.id.church_retr_logg));

                }
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                getAuto().getToast(c, RhemaHiveClassReferenceConstants.ERROR_MESSAGE_GENERIC + e.getLocalizedMessage(), RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
            }
        });
    } else {
        getAuto().getToast(c, "Oops ! !..Seems we need an internet connection for this", RhemaHiveClassReferenceConstants.TOAST_SHORT_LEN).show();
    }


}

然后對於用戶查詢我有

public void retrUserDet(final String uid) throws NullPointerException{
    if(networkInfo != null && networkInfo.isConnectedOrConnecting() && networkInfo.isConnected()) {
        FirebaseFirestore fS = getFStore();
        rhemaCollRef = fS.collection("rhema_churches");
        rhemaCollRef.whereEqualTo("user_uid",uid).get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
            @Override
            public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
                if(!queryDocumentSnapshots.getDocuments().isEmpty()){
                    for(DocumentSnapshot doc : queryDocumentSnapshots.getDocuments()){
                        user_email = doc.getString("user_email");
                        user_fName  = doc.getString("user_fName");
                        user_lName = doc.getString("user_lName");

                        user_phone = doc.getString("user_phone");
                        user_pix_link = doc.getString("user_pix");
                        getTex(R.id.user_retr_email).setText(user_email);
                        getTex(R.id.user_retr_name).setText(retFullName(user_fName,user_lName));
                        getTex(R.id.user_retr_phone).setText(user_phone);
                        ld_wt_gl(c,user_pix_link,120,120,getImg(R.id.user_retr_logg));

                    }
                }

            }
        });

    }
}

關鍵是永遠不會過早地使您的數據庫結構復雜化......對於進入我的 Firestore 的任何類型的數據，它都有一個用戶類型，它也可以幫助我進行過濾器

謝謝 ！
