Python Project: Properties Maintenance System P7

November 14, 2021 2 comments

Subject: Writing a Full Application for Properties Maintenance System [Property: Showing the Records in Main property Table]
Learning : Python, Math, SQL, Logeic

[NOTE: To keep the code as simple as we can, We WILL NOT ADD any user input Varevecations. Assuming that our user will Enter the right inputs.]


After adding Records to the Main Property Table, we need to display the records on the screen. So now in this part (Part -7) we will write a function to display all the records. The Function name will be def show_property() the function is not taking any attribute and is Not returning any things. First we will print-out the Table-Header then we will run an [SQL: select * from table-name] command to fetch all the records, then will [for loop] and test-format to print all the records on the screen. Here is the Code ..

python project Properties Maintenance System code by ali radwani doha qatar

After i display the records, I notes that the Address-Column needs more than one row (in some cases), and it miss the line formating, so I wrote a function and call it def warp_text(tex,warp_on,nl_space) the function takes three arguments,
the test: it the text/string you want to print.
warp_on: is a number of character before the new-line.
nl_space: is the number of white-character in the new-line.
Here is the Code ..

 # Function to warp 

def warp_text(tex,worp_on,nl_space) :
    c = 0
    
    for t in range (len(tex)) :
        print(tex[t],end="")
        c += 1
        if c == worp_on :
            print('\n', ' '*nl_space, end="")
            c = 0 



Check all the codes in the Download Page..
End of Part 7

NOTE: If you Download this Part you MUST Run the Option 82 (82. Delete the Data-Base and Start Again.) from the Main Menu to do the following Updates:

  • Update the properties_t Table (Adding the number of BathRooms)
  • Update on create_tables Function.
  • Update on insert_zero_records Function.

If you did this in last part (6) then you don’t need to do it again


In Part-8 In the Next Part, after adding and showing the records we will write the Function to Delete a record from the Table.

Python Project: Properties Maintenance System P2

October 20, 2021 7 comments

Subject: Writing a Full Application for Properties Maintenance System
Learning : Python, Math, SQL, Logeic

[NOTE: To keep the code as simple as we can, We WILL NOT ADD any user input Varevecations. Assuming that our user will Enter the right inputs.]

In Part-2 we will start writing the Functions in our app, to start I select the Payment Methods, this is a Look-up Table that will help the user to select come values, by defualt when you install the application and select to create the database, [in Part-1] we Insert some data all lookup-tables, So here in payment Method we have [Cash, Card, Cheque]. Our Functions will be Add New Payment Method, Edit a Payment Method and Delete a Payment Method.
Once i start writing the Edit Function, i notes that we need another two Functions to Help-up theyare: get_lookup_values(tname,t_id,key_id) and check_availabilty(dt, d_id, check_id) both not printing any thing on the screen just returning a Value.
get_lookup_values(tname,t_id,key_id) Here we pass the Table-Name, the ID field and key_id we want to return it’s Value.

check_availabilty(dt, d_id, check_id) This function will return True if the ID we send in ‘check_id’ is in the Data-Table dt.

So, let’s start with Add New Payment Method, We will ask the user to write the New Payment Method the will run the SQL command to Insert it into the data-base.. Hear is the Code ..

 # Add Payment Method

def add_pay_method():
    os.system('clear')
    line2 = "Add Payment Method"
    header(line2, 9,14)
    
    print('\n\n     List of the Payment Methods in the System ..  \n')
    show_lookup_data('Yes' ,'pay_meth_t','pm_id')
    
    print('\n     Enter a New Payment Method to the System.')
    print("     [E, Space or just Pressing Enter will be as 'Exit'].\n")
    
    new_pm =  input('     Enter a New Payment Method > ')
    
    if new_pm in ["e","E", "", " "] : 
        input ('\n     You Select to Exit .. Press any key > ')
        return
    else:
        c.execute ("INSERT INTO pay_meth_t (p_method) VALUES(:p_method)",{"p_method":new_pm.capitalize()}) 
        db_conn.commit()             
        
        input('\n     Done .. One record Added to the Data-Base .. Press any Key .. > ')
        return

Now, we will go to Edit a Payment Method that we have in the DataBase, here we will list all the Data we have on the screen, and will ask the user to Select the one to be edit, we will check the availability of the ID using the def check_availabilty(dt, d_id, check_id) Function and then [if the ID is available] we will use the def get_lookup_values(tname,t_id,key_id): function to fetch the key-value of that ID, then asking the user to Enter the New/Edited one. Here is the code..

Last Function in this part is to Delete a Payment Method from the Databsae, here also we will display all the contents of the table on the screen, and ask the user to select the one tobe deleted, we will check the availability of the ID and ask the user to confirm the Deleting action, then will call the SQL command to delete the entry. Here is the code..

In Part-3 In coming post we will continue writing Lookup Table Functions to Add, Edit and Delete there data.

Drafting New System

September 22, 2021 Leave a comment

Start to write down some notes and ideas for a new system/application using a self-brainstorming session.

I am always using the MindJet Maps app to draw the basic outlines of the application I want to work on.

Here is the first Draft of a Payroll System that I want to do in coming weeks. Not sure if I will use Python or MS-Excel to do this project.

Python: My Orders Tracker P-4

March 17, 2021 Leave a comment


Learning : Pythn, sqlite, Database, SQL
Subject: Create a system to track the orders

In this last part we will write the code to Edit an Order, in editing an order function first we will show all orders and will ask the user to select the one to be EDIT, then we will display that order detail on the screen and ask the user to confirm the action by entering ‘Y’ [our code will handel both y and Y]. We will ask the user about each attribute in the Order details if it need to be change or [Just press Enter to Keep the Current Data], also if the user enter ‘e’ or ‘E’ we will exit from the Editing mode.

Here is the code ..

# Function to Edit an Order

def edit_order():
    os.system('clear')
    print("\n==========[ Edit Orders ]==========")
    
    show_order('yes')
    
    edit_order = input('   Select the Order ID to be Edited. [E to Exit] > ')
    
    if edit_order in ['e','E'] : 
        return
    elif not edit_order.isnumeric() :
        input('\n   You need to enter an Order''s ID [Numeric]. .. Press any Key .. ')
        return 
               
    try:        
        
        c.execute ("select * from orders where o_id ={}".format(edit_order))  
        order_list = c.fetchone() 
        
        if order_list == [] :
            input('\n   ID {} Not Exsist. .. Press any key to continue.  '.format(edit_order))
            return
        
        os.system('clear')
        print("\n==========[ Edit Orders ]==========\n")
        print('\n   Details of the Order you select:\n ')
    
        print(" "*15,"ID: ",order_list[0])

        pass

[All the System Codes available in Download Page.]



Finish: Now we have an application that will store and retrieve our simple order data.
Enhancement:
We can do some enhancement in [link and image] data part to show and display them in better way.

Python: My Orders Tracker P-3

March 10, 2021 1 comment


Learning : Pythn, sqlite, Database, SQL
Subject: Create a system to track the orders

In this part we will write the code to Delete an Order that we have from our system, also we will add some validations on the user input, like if the user enter something not from the menu, or to do so, first we will re-call the show_orders() function that we have and passing the ‘yes’ parameter which means we are calling the function from inside another function [we will not print the function header, and will not clear the screen]. Then we will ask the user to select/Enter the ID of the order to be Deleted, after that we will print tha order details again on the screen and ask the user to confirm Deleting command by entering ‘Y’ … thats it.. let’s write the code..

# Delete Order

def del_order():
os.system('clear')
print("\n==========[ Delete Orders ]==========\n")

show_order('yes')

del_order = input(' Select the Order ID to be Deleted. [E to Exit] > ')

if not del_order.isnumeric() :
input('\n You need to enter an Orders ID [Numeric]. .. Press any Key .. ')
return

elif del_order in ['e','E'] :
return

try:
c.execute ("select * from orders where o_id ={}".format(del_order))
order_list = c.fetchone()

if order_list == [] :
input('\n ID {} not exsist.'.format(del_order))
return

os.system('clear')
print("\n==========[ Delete Orders ]==========\n")
print('\n Details of the Order you select:\n ')

print(" ID: ",order_list[0])
print(" Date: ",order_list[1])
print(" Order Number: ",order_list[2])
print(" Price: ",order_list[4])
print(" Quantity: ",order_list[5])
print(" Shipment Price: ",order_list[6])
print(" Total Cost: {:.2f}".format((order_list[4]*order_list[5]) + order_list[6]))
print("\n Description:",order_list[3])
print(" Image:",order_list[8])
print(" Link:",order_list[7])

user_confirm = input("\n\n You Select to DELETE the above Order, Enter Y to confirm, E to Exit. > ")
if user_confirm in ['y','Y'] :
#To Delete the order..
c.execute ("delete from orders where o_id ={}".format(int(del_order)))
db_conn.commit()

input('\n One record has been DELETED ... \n ... Press any key to Continue ...')

elif user_confirm in ['n','N']:
input("\n You select not to DELETE any thing. Press any key to Continue .. ")

elif user_confirm in ['e','E']:
input("\n You select stop the process and EXIT. ... Press any key to Continue .. ")
return

else:
input('\n Wrong input ... Press any key to continue ..')

except:
pass
The user select #3 from the menu to Delete an Order

The screen display the list of orders we have in the system, and the user select Order ID Number 3 to delete it.
The screen display the details of the order ID 3 and ask the user to confirm the deleting by entering ‘Y’

In Next Post: In the coming post P4 , we will write the codes to Edit an order information.

Library System with Excel -P1

November 11, 2020 3 comments


Learning :Excel formulas and VBA Cods
Subject: To Develop a Library System with Excel

Someone asked if we can do the Library Management system using Excel, so in the coming several posts we will try to develop an Excel File to store our Books. So I will stop the CRM Project and will work on Library System, we will use MS-EXCEL and VBA code to create a simple spreadsheet looking after our Books.

To start, do the following:
1. We will create an empty Excel file and call it “my Library System” and save it as “Excel Macro-Enabled Workbook.xlsm”
2. Create 7 Tabs(Sheets), name them as:
Menu, Books, Authors, Classifications, Data, Setting, Summary

In this post (Part-1), we will work on the Menu sheet, I will not concern about the themes and colors or fonts all this is back to each user to do formating as needed. So let’s begin with creating four buttons using the insert – shapes Rectangle: Rounded Corners.

We need to create four Rectangle: Rounded Corners, align them as you want and use any theme color, then give each a Captions as in the coming image..

Now, select the Books Button and with Right-Mouse-button select “Assign Macro” and from the new Assign Macro pop-up screen click on New.

This will launch the VBA Application with an open window to write our code, here is the code that if the user clicks on ‘SAY’: Books-Button the Books Sheet will be selected. In coming image, you will find the codes for all buttons we have in the Menu.

Also, we create a code to take us back to the Menu sheets and we call the button MENU, we will add this Button to all sheets we have.


    Recap this part:

  • 1. We Create an Excel file.
  • 2. We Create 7 Sheets and named them.
  • 3. We Create Buttons for the Menu Sheet.
  • 4. We Create the Home Button.
  • 5. We wrote the VBA code so we /the user can navigate thrugh the system.
