Using Postgres Database With Kivy - Python Kivy GUI Tutorial #57

In this video I'll show you how to use the PostGres database with your Kivy apps with Python.

Postgresql is a very popular database for production level apps, and using it with Kivy is a breeze. In this video we'll host our Postgres database on Heroku using their free tier and connect it to our local Kivy app.

Hi John,
I was having issues trying to get the 'heroku addons' to work. I don't know if this has changed since you recorded this video, but I had to add onto the line you suggested:

heroku addons:create heroku-postgresql:hobby-dev -app (my app name).

The key was to add the --app with the app name
* change (my app name) to whatever your app name is, then it worked.
Keep up the great work!

Thank you very much Mr. Elder. While I was wandering around the "kitchensink" I encountered an error which said this: no such file found etc. So I clicked on them and I noticed there are brackets. {} I clicked the problematic lines and searched for this: "{name_kv_file}.kv" and I noticed that there is no "f" in front of the code. f"{name_kv_file}".kv So I solved something by myself without checking google. I do not have prior education in a university. Thank you very much.

Hello. Just found your youtube channel and so far you have been quite helpful. One thing I want to do is with TextInput. I want to use canvas.before to modify the actual canvas the text is drawn on so that I can make it rounded (specifically to 14 pixels), but it doesn't work properly. That is, the background is above the text, making the text invisible. How would I fix this issue?
Excerpt from my .kv file (this is in a floatlayout by the way):
TextInput:
border_width: 2
id: search
multiline: False
hint_text: "Search Contacts"
font_name: "Segoeuib"
font_size: 27
hint_text_color: (112/255, 112/255, 112/255, 0.49)
pos: 10, 353
size: 594, 36
text_size: self.size
halign: "left"
valign: "center"
padding: [51, 0]
background_color: 0, 0, 0, 0
canvas.before:
Color:
rgb: (112/255, 112/255, 112/255)
RoundedRectangle:
size: [self.width+self.border_width*2, self.height+self.border_width*2]
pos: [self.x-self.border_width, self.y-self.border_width]
radius: [14]
Color:
rgb: (242/255, 242/255, 242/255)
RoundedRectangle:
size: self.size
pos: self.pos
radius: [14]
