SQLite connecting to tableview

Rufat

Hi, I’m new to Pythonista, and I’m struggling with binding SQLite data to custom Tableview and then in UI form. Here is my code. What I’m doing wrong?

          import ui
          import sqlite3 as dB
       #tv = ui.TableView()
       conn = db.connect('pythonsqlite.db')
       conn.row_factory = lambda cursor, row: row[0]
       c = conn.cursor()
       ids = c.execute('SELECT name FROM projects').fetchall()
       print(len(ids))

       #tv.data_source = ui.ListDataSource(ids)
       #tv.present('fullscreen')


        class MyTableViewDataSource (object):
    def tableview_number_of_sections(self, tableview):
         # Return the number of sections (defaults to 1)
         return 1

     def tableview_number_of_rows(self, tableview, section):
	# Return the number of rows in the section
	return (len(ids))

    def tableview_cell_for_row(self, tableview, section, row):
	# Create and return a cell for the given section/row
	cell = ui.TableViewCell()
	data_source = ui.ListDataSource(ids)
	cell.data_source = cell.delegate = data_source
	print(ids)
	return cell

def tableview_title_for_header(self, tableview, section):
	# Return a title for the given section.
	# If this is not implemented, no section headers will be shown.
	return 'Names'

def tableview_can_delete(self, tableview, section, row):
	# Return True if the user should be able to delete the given row.
	return True

def tableview_can_move(self, tableview, section, row):
	# Return True if a reordering control should be shown for the given row (in editing mode).
	return True

def tableview_delete(self, tableview, section, row):
	# Called when the user confirms deletion of the given row.
	pass

def tableview_move_row(self, tableview, from_section, from_row, to_section, to_row):

	# Called when the user moves a row with the reordering control (in editing mode).
	pass
             t=ui.TableView()
             t.frame=(0,0,200,480)
             t.data_source=MyTableViewDataSource()
             t.present('sheet')

             #ui.load_view('MyForm').present('sheet')

I did it with custom tableview, but how can I did the same with existing one in ui form?

@Rufat, if I understand you correctly, give the tableview a name in the UI designer, then get a reference to it by using the loaded_view['my_tableview_name'] syntax, then set the data source you have above.

Rufat

Thank you so much, I got it. But how it works if I have multiple columns?

mikael

@Rufat, it is a bit more complicated, but certainly possible. See @cvp’s example here.

Thank you @mikael, this example a little bit different. Is it possible to put some labels in the row of tableview and then get reference that label1 is the name from database, label 2 surname as example.

import ui,sqlite3

database = "database.db"

con = sqlite3.connect(database)
cursor = con.cursor()

users_query = "select * from users"
user_sections ="SELECT * FROM users INNER JOIN post on post.user_id = user.id"

user_names = [x[1] for x in cursor.execute(users_query)]

v = ui.load_view()
table = v['table']
table.data_source.items = user_names
v.present()

To add accessories:

user_names = [{"title":x[1],"accessory_type":"disclosure_indicator"} for x in cursor.execute(users_query)]
