You can get algo a row by ID by:
row = db.model_name(ID)
Where ID stand for the actual record id.

I have the following code for my DB:
dbmyhealth.define_table("health",
Field('name', 'string'),
Field('definition', 'text', length=
1000000,),
Field('abnval', 'text', length=
1000000,),
Field('normval', 'text', length=
1000000,),
Field('administration', 'text',
length= 1000000,),
Field('screening', 'text', length=
1000000,),
Field('causes', 'text', length=
1000000,),
migrate = False)
rows = dbmyhealth().select(dbmyhealth.health.ALL)
for row in rows:
location0 = row.name
location1 = row.definition
location2 = row.abnvalinterpret
location3 = row.normvalinterpret
location4 = row.administration
location5 = row.screening
location6 = row.causes
corpus = [location1 , location2, location3, location4,
location5, location6]
I want to select an item, including all the fields from the abnval
to the causes,not randomly but based on the ID or the name. If I
use the limitby constraint,I can get either the first, second, or
last item based on the selection used. If I use the below code, I
get only the first item, which is everything based on obesity. I
want to select any item with every query using either an ID or the
names below e.g.
A code like:
for row in rows:
if id == 2
code..
corpus = [location1 , location2, location3, location4,
location5, location6]....in this case my corpus will have
everything on cardiomyopathy using the table details below.
id name
0. diabetes
1. hypertension
2. cardiomyopathy
3. copd
4. obesity
So how do I code it to obtain my answer
Kind regards
Wouldn't that be either of
rows = dbmyhealth(dbmyhealth.health.id == 2).select()
or (if you were doing more with the query)
query = dbmyhealth.health.id == 2
rows = dbmyhealth(query).select()
?
(I didn't put in a first() because there's only 1 row with id == 2.)
