When i click on menu then show sub menu user.when click on user then show list of user when i click on any row of user then show error IndexError: list index out of range.
update_states() function does not update in database
1.When i click on menu then show sub menu user.when click on user then show list of user when i click on any row of user then show error like attached image.
You are iterating over rows, you have only two rows but 3 columns
update_states() function does not update in database
I don't think that the compilator terminates that function because there are few errors in it
To get your code works I had to make many changes
First prepare the data of the rvs in the python file
...
class RV(BoxLayout):
data_items = ListProperty([])
col1 = ListProperty()
col2 = ListProperty()
col3 = ListProperty()
def __init__(self, **kwargs):
super(RV, self).__init__(**kwargs)
self.get_states()
def update(self):
self.col1 = [{'Id': str(x[0]), 'Name': x[1], 'Code': x[2], 'key': 'Id'} for x in self.data_items]
self.col2 = [{'Id': str(x[0]), 'Name': x[1], 'Code': x[2], 'key': 'Name'} for x in self.data_items]
self.col3 = [{'Id': str(x[0]), 'Name': x[1], 'Code': x[2], 'key': 'Code'} for x in self.data_items]
def get_states(self):
#cur.execute("SELECT * FROM `m_state` order by state_id asc")
#rows = cur.fetchall()
rows = [(1, 'Yash', 'Chopra'), (2, 'amit', 'Kumar')]
# create data_items
'''for row in rows:
for col in row:
self.data_items.append(col)'''
i = 0
for row in rows:
self.data_items.append([row[0], row[1], row[2], i])
i += 1
self.update()
...
then in the kv replace the data of the rvs by col1, col2, col3 respectively
...

To change automatically the text of the buttons of the rvs when you edit them I had to schedule a function

Finally edit the updtate_states of the MainMenu class:

# update data_items
# obj.start_point + 1 --- skip State_ID
self.rv.data_items[obj.index] = [ obj.col_data[0], obj.col_data[1], obj.col_data[2], obj.index]
self.rv.update()
# update Database Table
cur.execute("UPDATE m_state SET state_name=?, state_code=? WHERE state_id=?",
(obj.col_data[1], obj.col_data[2], obj.col_data[0]))
con.commit()
Please be careful when making those changes. I hope this helps

1. In above image state code shows 111,112,113,114 which are static.How to show dynamic these state code.I am retrieve data from database which looks
rows = [(1, 'test1', 111), (2, 'test2', 112), (3, 'test3', 113), (4, 'test4', 114)]
In third index value are coming 111,112,113,114.How to put these value in spinner.
you can set a listproperty attribute in your group class then in the kv set the values of the spinner with this list:
in the .py:
...
class Group(App):
#cur.execute("SELECT * FROM `m_state` order by state_id asc")
#rows = cur.fetchall()
#print(rows)
rows = [(1, 'test1', 111), (2, 'test2', 112), (3, 'test3', 113), (4, 'test4', 114)]
r = ListProperty()
r = [str(t[2]) for t in rows]
...
then in the .kv:
...
Spinner:
text: "State Code"
values: app.r
...
I have used Lisproperty in case the values change in the future

Can anyone help me?
When i click on test then sub menu will be open.When i click on state then it look like good.But i click on city then distance increase between 'Test' and Row.
when i click on 'city' then show rows of city.when i click on any row then it looks Select state(treeview) show behind of 'update state'
I want it up on update state when anyone type anything in 'state Id'
i am using treeview in select state.how to add scrollbar in select state.when state increase then scroll will be good option
After update code I have a more error.
1. When i select state from select state then it's not put that string in state Name.Its showing error
File "/usr/share/kivy-examples/gst_fact/test.kv", line 50, in
app.root.stateName.text = self.text
AttributeError: 'MainMenu' object has no attribute 'stateName'
I want to when i click on anyone(state,city,area) then row show top position like Image_1.
It's because you have set the rules of your main menu in your kv to reserve the space for each box city, state and area. You can remove these rules and add only one box which I called states_cities_or_areas:
...
<MainMenu>:
states_cities_or_areas: states_cities_or_areas
dropdown: dropdown
BoxLayout:
orientation: 'vertical'
#spacing : 10
BoxLayout:
canvas.before:
Rectangle:
pos: self.pos
size: self.size
size_hint_y: 5
MenuButton:
id: btn
text: 'Test'
size : (60,30)
on_release: dropdown.open(self)
CustDrop:
id: dropdown
auto_width: False
width: 150
DropdownButton:
text: 'State'
size_hint_y: None
height: '32dp'
on_release: root.display_states()
DropdownButton:
text: 'City'
size_hint_y: None
height: '32dp'
on_release: root.display_cities()
DropdownButton:
text: 'Area'
size_hint_y: None
height: '32dp'
on_release: root.display_areas()
BoxLayout:
size_hint_y: 2.5
canvas.before:
Rectangle:
pos: self.pos
size: self.size
Color:
rgb: (1,1,1)
Label:
size_hint_x: 45
BoxLayout:
id: states_cities_or_areas
size_hint_y: 89
Label:
size_hint_y: 1
...
then change some methods and attributes of the mainmenu in the .py:
...
class MainMenu(BoxLayout):
states_cities_or_areas = ObjectProperty()
rv = ObjectProperty(None)
dropdown = ObjectProperty(None)
#Define City Variable
rvcity = ObjectProperty(None)
#Area City Variable
rvarea = ObjectProperty(None)
def display_states(self):
self.dropdown.dismiss()
self.remove_widgets()
self.rv = RV()
self.states_cities_or_areas.add_widget(self.rv)
def display_cities(self):
self.dropdown.dismiss()
self.remove_widgets()
self.rvcity = RVCITY()
self.states_cities_or_areas.add_widget(self.rvcity)
def display_areas(self):
self.dropdown.dismiss()
self.remove_widgets()
self.rvarea = RVAREA()
self.states_cities_or_areas.add_widget(self.rvarea)
def remove_widgets(self):
self.states_cities_or_areas.clear_widgets()
...
I have noticed that the tiles of colums of city was not displayed, you can display it with this in the kv:
...
<RVCITY>:
BoxLayout:
orientation: "vertical"
GridLayout:
size_hint: 1, None
size_hint_y: None
height: 25
cols: 5
...
when i click on 'city' then show rows of city.when i click on any row then it looks Select state(treeview) show behind of 'update state' like image_4 I want it up on update state when anyone type anything in 'state Id' like image_5
It's because the StateId text input is already on_text before the the popup opens. I suggest you to replace on_text with on_focus:
...
<EditCityPopup>:
title: "Update State"
size_hint: None, None
size: 500, 400
auto_dismiss: False
BoxLayout:
orientation: "vertical"
GridLayout:
cols: 2
backgroun_color: 0, 0.517, 0.705, 1
spacing: 10, 10
Label:
text: "City Id"
Label:
id: cityId
text: root.col_data[0]
Label:
text: "State Id"
TextInput:
id: stateId
text: root.col_data[1]
on_focus: root.display_states_treeview(self)
...
i am using treeview in select state.how to add scrollbar in select state.when state increase then scroll will be good option
You just have to put the treeview in a scrollview:
...
<TreeViewLabel>:
size_hint_y: None
height: 24
on_touch_down:
app.root.stateName.text = self.text
app.root.select_node(self)
app.root.popup.dismiss()
<TreeviewGroup>:
treeview: treeview
title: "Select State"
size_hint: .3,.3
auto_dismiss: False
BoxLayout
orientation: "vertical"
ScrollView:
size_hint: 1, .9
BoxLayout:
size_hint_y: None
id: treeview
height: root.h
Button:
size_hint: 1, 0.1
text: "Close"
on_release: root.dismiss()
and in the .py:
...
class TreeviewGroup(Popup):
treeview = ObjectProperty(None)
tv = ObjectProperty(None)
h = NumericProperty(0)
#ti = ObjectProperty()
def __init__(self, **kwargs):
super(TreeviewGroup, self).__init__(**kwargs)
self.tv = TreeView(root_options=dict(text=""),
hide_root=True,
indent_level=4)
for branch in tree:
populate_tree_view(self.tv, None, branch)
#self.remove_widgets()
self.treeview.add_widget(self.tv)
Clock.schedule_once(self.update, 1)
def remove_widgets(self):
for child in [child for child in self.treeview.children]:
self.treeview.remove_widget(child)
def update(self, *args):
self.h = len([child for child in self.tv.children]) * 24
Update
FOR THE 4TH POINT;
to pass the stateName to the other popup,keep the instance of the first popup when you create the 2nd:
...
class TreeviewGroup(Popup):
treeview = ObjectProperty(None)
tv = ObjectProperty(None)
h = NumericProperty(0)
#ti = ObjectProperty()
popup = ObjectProperty()
...
class EditCityPopup(Popup):
...
def display_states_treeview(self, instance):
if len(instance.text) > 0:
if self.popup is None:
self.popup = TreeviewGroup()
self.popup.popup = self
self.popup.open()
To reach the first popup in the kv make those changes:
in the .py:
...
class MyBoxLayout(BoxLayout):
rooot = ObjectProperty()
...
In the kv:
...
<TreeViewLabel>:
size_hint_y: None
height: 24
on_touch_down:
root.parent.parent.rooot.popup.col_data[1] = self.text
#app.root.select_node(self)
root.parent.parent.rooot.popup.popup.dismiss()
<TreeviewGroup>:
id: treeview
treeview: treeview
title: "Select State"
size_hint: .3,.3
size: 800, 800
auto_dismiss: False
BoxLayout
orientation: "vertical"
ScrollView:
size_hint: 1, .9
MyBoxLayout:
size_hint_y: None
id: treeview
height: root.h
rooot: root

Can anyone help for resolve some issue??
1. when i click on state (submenu of view) again and again then data repeats.How to avoid it.When i click on state then state list should be show and when i click on city then city list should be show.display_city() i have not written yet this for only example.
2. When i click on cancel two times then it shows error IndexError: list index out of range.
3.When i update state then it updated in database but does not change real time on screen.If i again run then shows updated data.
Please refer to the problems, solutions and example to solve your problems.
Columns Repeated
Problem
Each time you clicked View, widgets are dynamically added. If you clicked View twice, the columns are repeated twice.
Solution
You have to remove the widgets each time before adding them dynamically.
def display_states(self):
self.dropdown.dismiss()
self.remove_widgets()
self.rv = RV()
self.states.add_widget(self.rv)
def remove_widgets(self):
for child in [child for child in self.states.children]:
self.states.remove_widget(child)
IndexError
Problem
Whenever you clicked on each row of data, it invokes the on_press method. The self.start_point is initialized at the beginning when the class SelectableButton is instantiated.
Solution
Initialize self.start_point in the on_press method.
def on_press(self):
self.start_point = 0
end_point = MAX_TABLE_COLS
rows = len(self.rv_data) // MAX_TABLE_COLS
for row in range(rows):
if self.index in list(range(end_point)):
break
self.start_point += MAX_TABLE_COLS
end_point += MAX_TABLE_COLS
popup = EditStatePopup(self)
popup.open()
RecycleView Not Updated
Problem
In the method update_states, RecycleView's data update is missing.
Solution
Add the following to update RecycleView's data.
def update_states(self, obj):
# update data_items
# obj.start_point + 1 --- skip State_ID
for index in range(obj.start_point + 1, obj.start_point + MAX_TABLE_COLS):
self.rv.data_items[index] = obj.col_data[index - obj.start_point]
# update Database Table
cur.execute("UPDATE m_state SET State_Name=?, State_Code=? WHERE State_ID=?",
(obj.col_data[1], obj.col_data[2], obj.col_data[0]))
con.commit()
