We will create a GUI APP with python with firebase login and signup functions .
Step 1 --> The first step to do is to create a firebase project .
Go to the firebase console on https://console.firebase.com -> Then create a new project -> Go the project settings to check the config details . If you do not find them then create a new firebase web project .
Step 2 --> The second step is to create a new python file with the name firebase.py or main.py (name doesn't matter). Then use pip install pyrebase (For Windows).
pip install pyrebase
Step 3--> The third step is to install PyQt5 by using pip install pyqt5 (For Windows) -> Then install pip install pyqt5-tools (For Windows)
pip install PyQt5
pip install pyqt5-tools
from PyQt5 import QtCore, QtGui, QtWidgets
import sys
import pyrebase
Step 4 -- > Initialize Firebase with Pyrebase
config = {
"apiKey": "AIzaSyDZw2TKNMPLkFBI7qPzklTGbd8bYkIyfUc",
"authDomain": "py-firebase-f97fc.firebaseapp.com",
"databaseURL": "https://py-firebase-f97fc-default-rtdb.firebaseio.com",
"projectId": "py-firebase-f97fc",
"storageBucket": "py-firebase-f97fc.appspot.com",
"messagingSenderId": "130186938120",
"appId": "1:130186938120:web:d8b87ef2a01af62dbf4ebd",
"measurementId": "G-9R811DMZEL",
"serviceAccount":".\py-firebase-f97fc-firebase-adminsdk-7w4qw-52ae79b7e5.json"
}
firebase = pyrebase.initialize_app(config)
Step 5 --> Check whether there is already an user present or not
try:
IsUser=user['userId']
except:
IsUser = None
Step 6 --> On step 6 we start defining the auth
auth = firebase.auth()
Step 7 --> Now its the the time for creating a class and check if there is a user or not
class Ui_Dialog(object):
# if IsUser == None :
Step 8 --> We define the GUI . I have created it with Qt5 Designer , You can create your own or use my code for practice.
def setupUi(self, Dialog):
Dialog.setObjectName("Python with Firebase")
Dialog.resize(447, 621)
self.gridLayout = QtWidgets.QGridLayout(Dialog)
self.gridLayout.setObjectName("gridLayout")
self.verticalFrame = QtWidgets.QFrame(Dialog)
self.verticalFrame.setMinimumSize(QtCore.QSize(429, 300))
self.verticalFrame.setObjectName("verticalFrame")
self.verticalLayout = QtWidgets.QVBoxLayout(self.verticalFrame)
self.verticalLayout.setObjectName("verticalLayout")
self.lineEdit = QtWidgets.QLineEdit(self.verticalFrame)
self.lineEdit.setMinimumSize(QtCore.QSize(300, 40))
self.lineEdit.setMaximumSize(QtCore.QSize(500, 40))
self.lineEdit.setStyleSheet("border-radius:2px;\n"
"padding:2px;\n"
"content:'Email';\n"
"border:1px solid #262626;")
self.lineEdit.setObjectName("lineEdit")
self.verticalLayout.addWidget(self.lineEdit, 0, QtCore.Qt.AlignHCenter)
self.lineEdit_2 = QtWidgets.QLineEdit(self.verticalFrame)
self.lineEdit_2.setMinimumSize(QtCore.QSize(300, 40))
self.lineEdit_2.setMaximumSize(QtCore.QSize(300, 40))
self.lineEdit_2.setStyleSheet("\n"
"border-radius:2px;\n"
"padding:2px;\n"
"content:'Password';\n"
"border:1px solid #262626;")
self.lineEdit_2.setObjectName("lineEdit_2")
self.verticalLayout.addWidget(self.lineEdit_2, 0, QtCore.Qt.AlignHCenter)
self.toolButton_2 = QtWidgets.QToolButton(self.verticalFrame)
self.toolButton_2.setMinimumSize(QtCore.QSize(300, 40))
self.toolButton_2.setMaximumSize(QtCore.QSize(300, 40))
self.toolButton_2.setStyleSheet("background:#ccc;\n"
"border-radius:2px;\n"
"\n"
"")
self.toolButton_2.setObjectName("toolButton_2")
self.verticalLayout.addWidget(self.toolButton_2, 0, QtCore.Qt.AlignHCenter)
self.toolButton = QtWidgets.QToolButton(self.verticalFrame)
self.toolButton.setMinimumSize(QtCore.QSize(300, 40))
self.toolButton.setMaximumSize(QtCore.QSize(300, 40))
self.toolButton.setStyleSheet("background-color:#f23041;\n"
"border-radius:5px;\n"
"color:#fff;\n"
"")
self.toolButton.setObjectName("toolButton")
self.verticalLayout.addWidget(self.toolButton, 0, QtCore.Qt.AlignHCenter)
self.gridLayout.addWidget(self.verticalFrame, 0, 1, 1, 1)
self.toolButton_2.clicked.connect(self.signin)
self.toolButton.clicked.connect(self.signup)
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
self.toolButton_2.setText(_translate("Dialog", "SignIn"))
self.toolButton.setText(_translate("Dialog", "SignUp"))
On the next step we will define the onclick controls for the signin and signup buttons , whose onclick function has already been declared
self.toolButton_2.clicked.connect(self.signin)
self.toolButton.clicked.connect(self.signup)
Step 9 --> The Onclick functions
def signup(self):
email = self.lineEdit.text()
password = self.lineEdit.text()
user = auth.create_user_with_email_and_password(email, password)
user = auth.refresh(user['refreshToken'])
print('Sucessfully accounted in: {0}'.format(user['userId']))
IsUser=user['userId']
def signin(self):
email = self.lineEdit.text()
password = self.lineEdit.text()
user = auth.sign_in_with_email_and_password(email, password)
user = auth.refresh(user['refreshToken'])
print('Sucessfully logged in: {0}'.format(user['userId']))
IsUser=user['userId']
Here we have declared the firebase login and signup functions with a message that would be printed on the console and you can see it if the task is successful.
On the basis of what task you perform
Step 10 --> On the last and final step lets start the window with an if statement
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_Dialog()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
Run the app ...
