Join Gavin Green in our latest installment from the "In-depth... so if I come back into this
um I logged on with the user that
doesn't have access but that's perfectly
fine if you look at the agent over here
you can see that we have the URL the key
but down here where we start seeing
identifier typically the identifier
would be you know a unique identifier
and asset key Etc so I'm assuming stop
ID is the identifier yeah
and then down the bottom if you're
looking for multiple from the cache size
so you want 20 records from the cash
site typically you would include the
identifier in that option as well as you
know a timestamp or I'm assuming if the
uh the longitude is going to change
that will allow you to get the 20
records
so the the only thing here would be to
make sure that you just select the the
stop ID there and then just apply it
now when you come to cash per entity and
replace cache how the cache works is
this is storing data
that will be rendered and and visible on
the actual app side of things
so the the data coming in here because
you've specified a cache of 20.
and you haven't said cash per entity
you're only ever going to get 20 records
which might be what you're looking for
however if you want 20 records per stop
then what you do is by ticking this here
here and you select that option there
you're essentially going to create 20
per entity for stops that's how you
let's say you read the agent piece
coming down here so you got everything
else spot on
this is just an extra item here if that
is what you're looking for there are
times when you don't need it you just
want 20 records irrespective of you know
the the unique identifier or the stop ID
or the asset ID
however there are times when you
probably do want to have 20 per you know
stop ID
so just switch that option on there and
that'll help you with the caching pieces
um so now yeah let's not save the
changes
the data coming now when we come in here
um
this was some of the access rights that
I had to just make sure what accent
yes I do
um to just reallocate to to your user so
how you configure it is correct so here
what you want to do is
um let's set it
live data is coming in
for for that connector and then here you
just want to scroll down and actually
look for
your data stream now you may have
noticed you have access to a lot of
other data streams yeah I'm going to
explain I'll explain where those came
from and why we gave you access to them
once you've clicked that it'll bring in
the primary key for you
this bottom option here you need to
select it and then you can click save
now once you've selected that option now
you can actually pass some data to the
screen the reason you select this option
here
is
you want to be able to show this data
constantly changing on the app
without having to refresh the page
so what that means is if I
um if I don't tick the live option I
have to press F5 on the page every
single time to actually load it
okay
what the the live update so you'll see
it keeps changing for the 20 the 20
records I don't have to let's just leave
the master I don't I don't have to
refresh the page or change the page
Etc it's the one item a few people tend
to miss the first time is they don't
check that box or know what that box
means and then when they get to this
page it'll load the first time
but to see the changes you have to press
F5 to to do that if you don't want that
you can just go back into the edit on
the page data and you just untick that
however whenever you're connecting to a
data stream like you're doing here it's
generally a good it's generally a good
thing to to take it because you don't
want to have to press F5 on the page
every single time the the point is to
get the live data coming through
okay
now there are some data sources where
you can't do this
SQL is one of them
so if you create a new connection so if
we go into the app data here and you say
you know what I actually want to connect
to to SQL and you configure all of this
you'll find that when you get to the
other side to actually use it SQL will
not have that option for you so it's not
something that every single one of these
connection has it's specific to the
connection that we're talking to make
sense
