name ‘date_login’ not defined....

sendog3c

Hello there:

Having problems defining names when:

c.execute('''CREATE TABLE IF NOT EXISTS logindata (date_login, user_name, pwd_user)''')

Thank you.

import ui
import sqlite3
import console

equis = 0
yee = 0
ancho = 800
alto = 800
bgcolor = 'white'
bordercolor = '#7c1a80'
borderwide = 5
nameapp = 'WELCOME TO HABITFUN'

class mainscreen(ui.View):
    def __init__(self, *args, **kwargs):
        self.frame = (equis,yee,ancho,alto)
        self.background_color = bgcolor
        self.border_color = bordercolor
        self.border_width = borderwide
        self.name = nameapp
        
        
conn = sqlite3.connect("logindata.db", check_same_thread=False)
c = conn.cursor()
c.execute('''CREATE TABLE IF NOT EXISTS logindata (date_login, user_name, pwd_user)''')

vanimation = mainscreen()
vanimation.present('sheet')

def chge_name():
    vanimation.name = 'HABITFUN'

def button1_tapped(sender):
		sender.superview.close()
		vanimation.close()
	
def button2_tapped(sender):
		c.execute("INSERT INTO logindata VALUES(?,?,?)", (date_login, user_name, pwd_user))
		conn.commit()
		conn.close
		
button1 = ui.Button(title = 'SALIR', alignment=ui.ALIGN_CENTER, bg_color = '#fff2f2', font_color = 'black')
button1.frame = (50,250,100,50)
button1.tint_color = 'black'
button1.border_width = 1
button1.action = button1_tapped

t1=ui.TextField(frame=(50,100,300,40))
t2=ui.TextField(frame=(50,200,300,40))

v.add_subview(label1)
v.add_subview(label2)
v.add_subview(button1)
v.add_subview(button2)
v.add_subview(t1)
v.add_subview(t2)

t1.begin_editing()

vanimation.add_subview(v1)

vanimation.add_subview(v)

Doesn't look like you defined those names... Do a search through your code, and see if you can find where those are defined!

Perhaps you meant to define those names from the text field values, but the code you posted doesn't.

Also, note in one case you are trying to execute with variable names, but in the other case you use literals.

JonB:
Thanks for your prompt answer. I am a very very beginner coding in any language (Python inclusive). So, my problem is in the following lines:

> def button2_tapped(sender):
>         c.execute("INSERT INTO logindata VALUES(?,?,?)", (date_login, user_name, pwd_user))
>         conn.commit()
>         conn.close``````

There is where the code crash.

Thanks again.

@sendog3c The code crashs for "name date_login is not defined".
And obviously, you have not defined the variables to be written in your db.
Then do this to get data you entered

        date_login = '20190101' # or what you want
        user_name = sender.superview['t1'].text
        pwd_user  = sender.superview['t2'].text

and this to give a name to the TextFields where you enter data

t1=ui.TextField(frame=(50,100,300,40),name='t1')
t2=ui.TextField(frame=(50,200,300,40),name='t2')

That is normal:
In the create statement, the variables names are littéral
In the insert statement, the variables names are variables

sendog3c

Thank you both.

Where can I manipulate sqlite3. I mean, Browse data, delete columns, etc.

Regards;

Do you want to say "where can I find how to..."?
If this is the question, there are a lot of docs, like this one

Example (be careful, your conn.close needs parentheses)

def button2_tapped(sender):
        date_login = '20190101' # or what you want
        user_name = sender.superview['t1'].text
        pwd_user  = sender.superview['t2'].text
        c.execute("INSERT INTO logindata VALUES(?,?,?)", (date_login, user_name, pwd_user))
        conn.commit()
        c.execute("SELECT * FROM logindata")
        rows = c.fetchall()
        print(rows)
        conn.close()

sendog3c

Yes I know there a lot docs here, but I mean if there is by example: a console to work with my DB alone or if there is way to use command line with specific sqilte3's instructions. supposing "sqlte3 /?".

Thanks.

cvp

@sendog3c you could write a little script like

import console
import sqlite3

conn = sqlite3.connect("logindata.db", check_same_thread=False)
c = conn.cursor()
#c.execute("CREATE TABLE IF NOT EXISTS logindata (date_login, user_name, pwd_user)")

while True:
	r = input()
	if r == 'close':
		break
	#PRAGMA table_info(logindata)
	#SELECT * FROM logindata
	c.execute(r)
	rows = c.fetchall()
	print(rows)
	
c.close()

It will ask you a sql command, execute it, fetch the results and print them
Try with
PRAGMA table_info(logindata)
Or
SELECT * FROM logindata

Of course, this is only valid for commands which can be followed by a fetch.
Up to you to modify the code to make it more generalized

sendog3c

Thanks again

I bought the SQLed app for quick checking things. The downside is you have to "share..." the sqlite db between the apps.

Btw. in the PythonCheatSheet is a sqlite section.

sendog3c

Thank you Brumm. I a going to check it.

I haven't tried it, but there is https://forum.omz-software.com/topic/2326/sqlite3-browser
