Hi,
I'm still not sure as to how to go about using this.
Say, I have a controller with the function list: and a function called
write:
if the function is list then read from slaves, if the function is
write, write to master.
So the correct code should be:
if request.function in
You could define 'read_only_actions' anywhere it makes sense, for example:
read_only_actions = ['list','another_read_action','yet_another_read_action']
if request.function in read_only_actions:
db =... ...
else
db =
Of course, if that one 'if' statement is the only place you
Hi, I did something similar,
if add in request.function:
db = DAL(['mysql://Database connection string'])
else:
print Using Slave Database
db = DAL(shuffle(['database connection string'])
That would and uses the slave database (readonly) but, I get this
error message.
Have all the tables already been created in the slave databases (web2py may
be trying to create tables or run migrations)? What happens if you do:
db = DAL(shuffle(['connection string']), migrate_enabled=False)

Hi Anthony,
That worked, maybe the docs should be updated.
I did try migrate=False, thought they were both the same thing.

Indeed.

migrate=False (as an argument to DAL) doesn't turn off migrations -- it
merely determines the
Hi Anthony,
yes, migrate is set for fields in the aut table.
Also another note, shuffle did not work for me I have to, from random
import sample.
then change
DAL(sample(['mysql connection string','mysql connection
string'],1),migrate_enabled=False)

Just changed the book example to use random.sample.

You would only use this if you have a replicated database. I.e. you
are running many database servers synced with each other. For example:

It would go in your model file -- the same place where you would normally

That's just some (incomplete) example code. You have to define
'read_only_actions' yourself. In that example, it would be a list functions
that only need to read (but not write) the database and can therefore be
given access to one of the slave databases.
Actually, it looks like the code has
