Corona SQL pass row ID in tableView to new Scene - sql

Question

I've found a similair question to my problem and so far its working for me, Im getting the row ID printed with a print statement.
I am displaying data from my Database in a tableView. With the onTouch function I want the data showed in a new Scene in a scrollView that gets that data specifically to that clicked row. So for example I am clikcing on the tableView on Capital_NL, it has to show Amsterdam in the scrollView (Scene 2).
This is my code so far:
Scene 1:
local count = 0
local baslikRow = {}
for row in db:nrows("SELECT dua_id, baslik FROM dua") do
count = count + 1
baslikRow[count] = {}
baslikRow[count].baslik = row.baslik
baslikRow[count].dua_id = row.dua_id
end
local function tableViewListener( event )
print(event.phase)
end
local function onRowRender( event )
local row = event.row
local rowHeight = row.contentHeight
local rowWidth = row.contentWidth
local options =
{
parent = row,
text = baslikRow[row.index].baslik,
x = 20,
y = 0,
font = native.systemFont,
fontSize = 16
}
local rowTitle = display.newText(options)
rowTitle:setFillColor( 0, 0, 0 )
rowTitle.anchorX = 0
rowTitle.x = 15
rowTitle.y = rowHeight * 0.5
end
local function onRowTouch( event )
local row = event.row
if event.phase == 'tap' then
print("Pressed rowNR: " .. row.index )
print("Pressed rowID: " .. event.target.params.paramID)
composer.gotoScene("scene2")
end
end
local tableView = widget.newTableView{
left = 0,
top = 0,
height = display.contentHeight,
width = display.contentWidth,
onRowRender = onRowRender,
onRowTouch = onRowTouch,
}
for i = 1, count do
tableView:insertRow
{
rowHeight = 50,
rowid = baslikRow[count].dua_id,
params = { paramID = baslikRow[i].dua_id }
}
end
sceneGroup:insert(tableView)
Scene 2:
---------------------
-- CREATE SCROLLVIEW
---------------------
local scrollView = widget.newScrollView
{
left = 0,
top = 0,
width = display.contentWidth,
height = display.contentHeight,
topPadding = 0,
bottomPadding = 0,
horiontalScrollDisabled = true,
verticalScrollDisable = false,
listener = scrollListener,
}
sceneGroup:insert(scrollView)
---------------------
-- GET DATA FROM DB
---------------------
for row in db:nrows("SELECT metni FROM dua") do
local rowParams =
{
duaID = row.dua_id,
Metni = row.metni,
}
local options =
{
text = row.metni,
x = display.contentCenterX + 20,
y = display.contentHeight / 2,
width = 300,
width = display.contentWidth,
font = native.systemFontBold,
fontSize = 18,
}
local t = display.newText(options)
t:setTextColor(0)
scrollView:insert(t)
end
What I have right now is, whenever I click on, for example Capital_NL or Capital_USA or Capital_Germany, I always get the result Amsterdam back.
How do I pass the data thats in the same Row in the database from Scene 1 to Scene 2

Answer 1

I think you want to display the (metni) data based on the row number tapped on the previuos scene ..
Try this inside scene1 ..
for row in db:nrows("SELECT dua_id, baslik, metni FROM dua") do
count = count + 1
baslikRow[count] = {}
baslikRow[count].baslik = row.baslik
baslikRow[count].dua_id = row.dua_id
baslikRow[count].metni = row.metni
inside the onRowTouch event handler:
composer.gotoScene("scene2",{params = baslikRow[row.index].metni})
This way you can pass the data you want to use .. I guess you don't need to use the database code inside scene2 ..
to access the data passed from scene1 to scene2
local selectedRow = event.params
Then ..
local options =
{
text = selectedRow,
x = display.contentCenterX + 20,
y = display.contentHeight / 2,
width = 300,
width = display.contentWidth,
font = native.systemFontBold,
fontSize = 50,
}
local t = display.newText(options)
t:setTextColor(0)
scrollView:insert(t)
I think thats what you asked for .. If NOT, please explain more and give us a screenshot of your "dua" table ..
