[web2py] When i JOIN something it goes ok, but if there is no join i got an error..
Hi all,
Just starting with Web2py and i feel like a kid in a play garden. ;)
Ok my problem, i am trying to make a simple JOIN but when i do that i
have a problem with my views.
My controlle looks like this:
def read():
thispage = db.topics[request.args(0)]
if not thispage:
redirect(URL(r=request, f='read'))
if auth.user_id:
form = form = SQLFORM(db.replys)
form.vars.topic_id = request.args(0)
form.vars.user_id = auth.user_id
if form.accepts(request.vars, session):
response.flash = 'Topic created!'
else:
form = 'need to login to reply'
db(db.topics.id==request.args(0)).select()[0]
#topics = db(db.topics.id==request.args(0)).select(db.topics.id==
db.replys.topic_id)
#replys =
db(db.replys.topic_id==request.args(0)).select(db.replys.ALL,
orderby=~db.replys.posted)
#query = (db.topics.id==db.replys.topic_id)&(db.topics.id ==
request.args(0))
rows= db(db.topics.id== request.args(0)).select(db.topics.title,
db.topics.content,
db.replys.content,
left=db.topics.on(db.topics.id==db.replys.topic_id))
return dict(rows=rows,form=form)
My view looks like this:
{{extend 'layout.html'}}
{{for row in rows:}}
{{=row.topics.title}}
{{=row.topics.content}}
{{pass}}
{{for row in rows:}}
{{=row.replys.content}}
{{pass}}
{{=form}}
When i have a few reply's then i have row.topics.titles and
row.topics.content as the same amount as the row.replys.content.
When i don't have a reply, then i don get the record back from topics.
Now my question: How do i get one time the topics record back, and
when there is none replys just the the record of the topic?
What am i missing at this point?
Thanks for the help.
regards, Bart
[web2py] Re: Upload file using the LOAD (....., ajax = True)
Hi Anthony,
This solution you mention is, with some minor changes, still working in the
current version. I've managed to get the change working in the 2.12.3
version of web2py.js:
Change function trap_form to:
trap_form: function(action, target) {
/* traps any LOADed form */
$('#' + target + ' form').each(function(i) {
var form = $(this);
if(form.hasClass('no_trap')) {
return;
}
form.attr('data-w2p_target', target);
var url = form.attr('action');
if((url === "") || (url === "#") || (typeof url === 'undefined'))
{
/* form has no action. Use component url. */
url = action;
}
/* begin change */
if(form.find('.upload').length>0) {
form.ajaxForm({
url: url,
success: function(data, statusText, xhr) {
jQuery('#'+target).html(xhr.responseText);
web2py.trap_form(action, target);
web2py.ajax_init();
}
});
} else { /* end change */
form.submit(function(e) {
web2py.disableElement(form.find(web2py.formInputClickSelector));
web2py.hide_flash();
web2py.ajax_page('post', url, form.serialize(), target, form);
e.preventDefault();
});
};
form.on('click', web2py.formInputClickSelector, function(e) {
e.preventDefault();
var input_name = $(this).attr('name');
if(input_name != undefined) {
$('').attr('name', input_name)
.attr('value', $(this).val()).appendTo(form)
}
form.trigger('submit');
});
});
},

Bart

[web2py] Re: error starting scheduler: error retreiving status
Hi Niphlod,
Normally i just put a record in the scheduler_task table with appadmin.
That works fine (no errors), but nothing happens because the scheduler
worker is not running.
In db.py the database schema is set via db.executesql("set search_path to
auth,scheduler, ... ;")
In case migrate is True, the search_path is set to scheduler, auth, ...
just before the scheduler = Scheduler(db) statement.

[web2py] Re: error starting scheduler: error retreiving status
Thanks Niphlod, It works!
I added
self.db_thread.executesql("set search_path to scheduler, auth, ... ;")
in gluon/scheduler.py
after the self.db_thread = DAL( line and before the
self.define_tables( ... line
I am aware of the fact that it is not supported, but the database uses a
strict schema policy so i don't have a choice really.
I am wondering how worker startup works when the python web2py.py -K myapp
statement is executed.
How does the scheduler get the database uri, if the models aren't executed
at scheduler worker startup?
Does scheduler only search for de db - DAL(... statement, omitting the
other code?

[web2py] Scheduler error using python3.6 and psycopg2
For a new application, i have installed web2py 2.16.1 under python 3.6 and using psycopg2 2.7.4 for postgresql access. Everything is working okay, except the web2py scheduler. After successfull execution of the first task, the scheduler gives an error in the send_heartbeat function. The task output is correctly stored in the database, with status COMPLETED. The transaction is committed. But then in the first heartbeat after completion, the error below is thrown: Looks like the database connection is lost unexpected. The strange thing is that this is only happening with psycopg2. When the PG8000 connector is used, everything is working fine. I have tested this on my development system (MacBook) On my production system under Ubuntu 16.04, the same thing is happening. Does anyone have a clue? The error: ERROR:web2py.scheduler.MyMac.local#21060:Error retrieving status Exception in thread Thread-30: Traceback (most recent call last): File "/Users/me/PycharmProjects/myapp/web2py/gluon/scheduler.py", line 1168, in send_heartbeat mybackedstatus = db(sw.worker_name == self.worker_name).select().first() File "/Users/me/PycharmProjects/myapp/venv/lib/python3.6/site-packages/pydal/objects.py", line 2250, in select return adapter.select(self.query, fields, attributes) File "/Users/me/PycharmProjects/myapp/venv/lib/python3.6/site-packages/pydal/adapters/base.py", line 762, in select return self._select_aux(sql, fields, attributes, colnames) File "/Users/me/PycharmProjects/myapp/venv/lib/python3.6/site-packages/pydal/adapters/base.py", line 718, in _select_aux rows = self._select_aux_execute(sql) File "/Users/me/PycharmProjects/myapp/venv/lib/python3.6/site-packages/pydal/adapters/base.py", line 712, in _select_aux_execute self.execute(sql) File "/Users/me/PycharmProjects/myapp/venv/lib/python3.6/site-packages/pydal/adapters/__init__.py", line 67, in wrap return f(*args, **kwargs) File "/Users/me/PycharmProjects/myapp/venv/lib/python3.6/site-packages/pydal/adapters/base.py", line 412, in execute rv = self.cursor.execute(command, *args[1:], **kwargs) psycopg2.OperationalError: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

[web2py] Re: Scheduler error using python3.6 and psycopg2
I have found a workaround for this issue. The root cause is probably something in the pyDal connector or psycopg2 or threading. I leave the finding of that to the experts. The workaround is to add code to gluon/scheduler.py to test the connection before the rest of the Scheduler.send_heartbeat() function is executed. If the connection-test fails, a new one is set up: Insert this code at the top of the Scheduler.send_heartbeat() function if self.db_thread: # BKR 20180612 check if connection still works, if not -> throw away self.db_thread and force reconnect try: x = self.db_thread(self.db_thread.scheduler_worker.worker_name == self.worker_name).select() except self.db_thread._adapter.connection.OperationalError: self.db_thread = None With this addition, the scheduler works okay.

[web2py] Re: web2py RESTful timeout
My python script is getting a stock price from google finance and then
posting (using RESTful api) to my web2py application every 15 minutes.
When I look at the log files everything works for awhile, but after a
couple hours every POST will timeout. If I load the application's
default/index page from a web browser then the RESTful POST works for
another hour or two and then it times out again. I've run the web2py
server on pythonanywhere and on a local computer with the same results.
r = requests.post(url, headers=headers, data=json.dumps(payload),
timeout=360)
def POST(table_name,**vars):
if table_name == 'VEXMX':
row = db(db.VEXMX.date==vars['date']).select().first()
if row:
result = {'exists':1, 'id':row.id, 'errors': {}}
result = dict(result=result)
else:
result = dict(db.VEXMX.validate_and_insert(**vars))
result['exists'] = 0
result = dict(result=result)
return result

I'm using MySQL, but I've also used SQLite. Yes I've verified that the POST is timing out. I ran another test and the script ran for 2 days until the error showed up again. I reloaded the default/index webpage in my browser and now its working again. I'll try disabling sessions as Derek suggests. Thanks.

[web2py] Re: web2py RESTful timeout
This didn't fix my problem. It worked for several days, but now I cant communicate to my server using RESTful services. I'm sure if I load the website from a browser it will start working again. This is very frustrating! It sure seems like the RESTful service goes into some type of sleep mode. On Wednesday, November 26, 2014 9:55:47 PM UTC-7, Bart wrote: > > Thanks I'm testing this now.

[web2py] Re: web2py RESTful timeout
Adding exception handling inside my RESTful api fixed my problem. Sometimes my RESTful posts contained corrupted data and this would cause an exception and hang future posts. Adding try/except solved my issue.

[web2py] Re: Web2py sessions table does not exist?
Migrations should be on. I have it enabled through my DAL:
db = DAL(settings.database_uri, migrate_enabled=True)
And through each individual table:
db.define_table('courses', ... migrate='runestone_courses.table')
I've emptied the entire databases/ folder of all the .table files.
This seems to have made the situation worst, since now I can't read error
tickets - clicking the link opens a new ticket. I've tried getting into my
application's errors/ files, and I see that this line is still in there:
Table \'runestone_dev.web2py_session_runestone\' doesn\'t exist
The latest error in the admin application's errors/ folder has this line:
can't pickle function objects

[web2py] Re: Web2py sessions table does not exist?
Ah, apologies. I was a little over-enthusiastic with my deletions.
So I did fake_migrate_all=True, let web2py create the tables, and then
turned off fake_migrations. However, web2py did not create a
web2py_session_runestone table file. All the other tables are there, just
no web2py_session_runestone.table. The sql.log file doesn't refer to it at
all.

[web2py] Re: When i JOIN something it goes ok, but if there is no join i got an error..
Hi villas,
Thnx for your reply.
I am only playing for a couple of day's with web2py and python.
I have more experience in php. ;)
As what i see now is that the JOIN is not correct i think..
going to give it another try.
speak to you later.

[web2py] Re: Field set the default value +1 on insert
Hello my friends, Thanks for the inspiration. The answer from Craig, looks to me a good idea how i can do it. many thanks, Bart -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Field set the default value +1 on insert
Hello web2py freaks,
In my first try to make an application with web2py i have a little struggle
how to accomplish as what is would like to see.
In db1.py i created a field like this:
db.define_table('jobticket',
Field('ticket', 'integer', default = +1) # ticket needs to
be ticket +1 when inserted
)
I need to have something called "ticket" what represent a number where my
other tables are linked to.
I know that the default id is auto increment, and i can reference it, so
that's not the point.
The ticket is a number what i needs to be set like : 15001. And that
needs to be inserted +1 if there is a new job.
15 is a year, the rest is just a number.
So, i have 2 problems:
- if there is a new year like 1 january 2016, the first two numbers
needs to be changed from 15 to 16?
- And how can i get the max number out of the database and insert that
with a new value( +1)
Does anybody have a good insperation or an good idea to get me on the right
track?
Many thanks.
Bart
