[web2py] Re: Need opinions/reviews about embedded jquery/javascript XHTML editor
I am using CKeditor as well, mainly because its basic version suits my needs, and in case I need other features its easily extendible. Furthermore it really is WYSIWYG. In case of TinyMCE I had to write my own style sheet to make the editor match my application's styling. In the past I also tried NicEdit, at the time it inserted div/div elements instead of p/p elements.

[web2py] Re: Bug in DAL with SQLFORM, upload field and required field ???
The value for dentista is correct, is equal to Nominativi.id selected in
drop-down list.
When I insert or update the record with 'logo' empty the query is generated
with '' instead of NULL and sqlite cannot parse the full query.
if I update with db.Consulenze.insert(dentista=1240) it woks.

[web2py] Re: upload e CASCADE delete
Thanks Anthony, I think you're right,
solution should be that after check
ondelete='CASCADE' and
check autodelete=True,
default _before_delete erase the associated files in uploads folder.
I posted an issue on Google Gode (n.1854).

Il giorno mercoledì 15 gennaio 2014 15:39:07 UTC+1, Anthony ha scritto:
The cascading delete is handled by the database, so the web2py DAL is not
executing the delete from the db.allegato table and therefore doesn't have
the opportunity to run the _before_delete and _after_delete callbacks (the
former is used to autodelete uploaded files).
I suppose you could create a _before_delete callback on the db.prodotto
table that does the file deleting. Maybe we could build this in to the
default _before_delete callbacks for tables -- it would check the
_referenced_by fields for ondelete='CASCADE', then check the referring
table for upload fields with autodelete=True, and then delete the
associated files (or maybe just run the _before_delete callback of the
referring table). You can post an issue on Google Code and reference this
thread.
In the documentation, we should probably note that the _before_delete and
_after_delete callbacks of a table will not be run when the delete happens
in the database as the result of a cascade.

[web2py] DAL usage
Our schema is quite large (200+ Tables) and changes very seldom. I was thinking, is there a way to not have to rebuild it in it's entierty on every request? I mean, is there a way to seperate-out the schema definition from the connection object? Ideally, I would put the schema definition code in a separate module in the modulesz folder, and import it into the model file that creates the connecfion, and somehow pass the ready-made schema-object(s) into the newly-created connection object on each request. Can this be done? What are the gotchas for this (if any)? Are there restrictions for somed schema-definitions tbat can not be used like this? -- 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] Redis caching
I noticed that the current implementation for web2py uses pickles. That is a design choice. There are pros and cons. Right off of my head, the biggest cons may be retricting cache-use to python, and performance penalties. When I think of all that redis can do, I can not help imagining a better solution - especially for caching query results. All result-sets are flat and simple in nature - before the dal steps in and converts them to row objects. This makes it an ideal candidate for redis. Has anyone thought of this already? A simplistic (naive) solution aould be to store every result in a hash, and stlre all the ids in a sorted set. This way, the result-sef in the cache may be queried by redis, and not necessarily be pulled in an all-or-nothing fasion, improving read-performance and resources dramatically, while opening the possibilities for external non-python processes to access the cache talking to redis directly. It may not be desierable for all use-cases, as there are obviouse security concearns, but for ipc stuff and/or intranet applications (which are a common use-case in the web2py world), this can be most beneficial.

How can I implement this in a view. I am not sure how to call that markmin
action to be used instead of MARKMIN helper.

There is an official syntax for this.
@{component:controller/function/args}
To enable this and enable OEMBED I do:
def markmin(body):
from gluon.contrib.autolinks import expand_one
def component(text):
items = text.split('/')
controller, function, args = items[0], items[1], items[2:]
return LOAD(controller, function, args=args, ajax=True).xml()
return MARKMIN(body, url=True, environment={'component':component},
autolinks=lambda link: expand_one(link, {})).xml()
db.table.field.represent = lambda v,r: markmin(v or '')
This is done automatically by auth.wiki()

Function to my previous ideas, a function as follows could handle both

I also included a simple check for allowed domains:
def __component(text):
if text and text.lower().strip().startswith('http'):
from urlparse import urlparse
allowed_domains = [
'www.domain1.com',
'www.domain2.com',
]
if allowed_domains and not any(i in urlparse(text)[1] for i
inallowed_domains
):
return H1('domain not allowed').xml()
else:
return LOAD(url=text, ajax=True).xml()
else:
items = text.split('/')
controller, function, args = items[0], items[1], items[2:]
return LOAD(controller, function, args=args, ajax=True).xml()
MARKMIN(mytext,url=True,extra=dict(component = lambda value: __component(
value)))
In our Markmin we can then include...
``http://www.domain1.com/app/mycont/myfunc/arg1``:componenthttp://www.domain1.com/app/mycont/myfunc/arg1:component
and/or
``mycont/myfunc/arg1``:component
.
Maybe someone has other better, or more flexibile, ideas?

This uses LOAD. What is recommended for loading components from other

are other ways, I am not sure that I am using the currently recommended
methods for Markmin.
Thanks!

from the form2 in the upload method above is how the link is made and the

But its like its not even using the custom retrieve cause why is looking

When that URL is requested, the grid itself handles the download by calling response.download(). response.download() will call field.retrieve(), which will call your custom_retrieve method, but the problem is that response.download() expects the filename to start with tablename.fieldname, and your custom_store method does not do that, so the file is not found. As an alternative, you can specify your own URL to handle the downloading via the upload argument to SQLFORM.grid. However, you're probably better off just using the built-in mechanism for uploads/downloads. The custom methods are for when you need to do something differently, but you largely appear to be replicating the built-in methods (though in a less secure way -- no file renaming or checks to prevent directory traversal attacks). Is there and example of using the built in way? Just define a field as an upload field, and uploads are handled automatically and downloads are easily handled with response.download(). If using the grid, everything will just work.

Re: [web2py] Re: Bootstrap3 package - help to test
Seems pretty clean... I would need to use it to find issue though and I am still with w2p 2.4.7 for now waiting for the new rname feature to be available (and stable)...

[web2py] Caching of Modules
I'm trying to import a local module into my application. I've got the following at the bottom of one of my model files: from gluon.custom_import import track_changes track_changes(True) It still appears to be caching the class definition. Has any of this code changed recently? Initially I was passing the class a dict of config variables like so: class ExampleClass: def __init__(self,config): self.config = config When I called it from the controller, it returned the dict. Then, when I changed the class file to self.config = 1, it was still returning the dict. Deleted the .pyc file and restarted the webserver and it gave me the new value.

[web2py] Re: DAL usage
If you set DAL(..., lazy_tables=True), most of the table definition code is deferred until the first time you call db.tablename, so tables that are not accessed on a given request are not fully defined. Of course, you can put the schema definition code into a function or class in a module and import and execute that function/class at request time, but the actual definition code would still have to run at each request (albeit, only for the tables you actually need for that request). It sounds like instead, you would prefer for the module to create a table object so the table object can be imported directly (and then added to the DAL connection object of the current request) -- that way, the table object would be created only once, the first time it is imported. This isn't possible with the current API, though I suppose you could create instances of the dal.Table class in the module and then write your own version of DAL.define_table to attach the imported Table objects to a DAL instance. Perhaps this could be made an option of the current .define_table() method (as it is, if you pass a Table object to .define_table(), it just makes copies of all the Field objects, but perhaps there could be an option to pass in a Table object that gets used as is). Not sure how much benefit there would be to this approach, assuming any given request doesn't involve too many table definitions -- lazy_tables, conditional models, and importing functions/classes from modules may be sufficiently speedy for most use cases.

[web2py] using CAS
Hi, I'm trying to use our university CAS server as the authentication for my web2py app. I am able to direct logins to CAS fine, by using this code in my model file: auth=Auth(db, cas_provider='https://securedev.its.yale.edu/cas') After completing the cas login, when I look at db.auth_user table, or session.auth.user, only auth_user.registration_id has a value, which is https://securedev.its.yale.edu/cas/rdb9. If I do subsequent logins using the same login name, web2py finds the existing user entry and gives me that id. So far so good.

Re: [web2py] Re: ultramemcache
I was going to, but couldn't find it... In fact, I even ran a full text-search on the entire web2py stack, and found no import memcache anywhere (nor from memcache for that matter...)

[web2py] Re: Redis caching
Derek: Are you being sarcastic and mean? cache doesn't cache only resultsets, hence pickle is the only possible choice. Well, not if you only need flat and basic objects - there the benefit of pickle is mute and it's overhead is obvious - take a look at this project: https://redis-collections.readthedocs.org/en/latest/ It's cool. Actually, I started developing something like that using DAL callbacks, but as soon as multiple tables are involved with FK and such, it starts to loose speed. Also, your whole app needs to be coded a-la ActiveRecord, i.e. fetch only by PK. Hmmm... Haven't thought of that... Well, you can't search/query for specific records by their hashed-values, but that's not the use-case I was thinking about - I am not suggesting replacing the dal... Plus, that restriction would also exist when using pickles for such a use-case... What I had in mind is simpler than that - just have a bunch of simple queries that you would do in your cache.ram anyways, and instead have their raw result-set (before being parsed into rows objects) and cached as-is (almost...) - that would be faster to load-in the cache than into cache.ram, and also faster for retrieval. BTW, I'm not properly sure that fetching 100 records with 100 calls to redis vs pulling a single time a pickle of 1000 records and discarding what you don't need is faster. Hmmm... I don't know, redis is famous for crunching somewhere in the order of 500K requests per-second - have you tested it? BTW2: ORM are already there: redisco and redis-lympid 10x, I'll take a look - though I think an ORM would defeat the purpose (in terms of of speed) and would be overkill... -- 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.

Have you checked app/databases/sql.log?
Maybe you can post the last commands stored for debugging.

[web2py] Re: using CAS
Hi Massimo, Thanks for the reply. I'm still not certain the best place to do this. Is there a callback within the login processing where I can stick this code, or should I use _next in the CAS redirect to go to a controller that will do this?

[web2py] Re: DAL usage
It sounds like instead, you would prefer for the module to create a table object so the table object can be imported directly (and then added to the DAL connection object of the current request) -- that way, the table object would be created only once, the first time it is imported. That's exactly what I meant. It would then refresh itself only when you make a change to the schema, as the module would have to be re-compiled on import-time on the next request. In most ORMs/DALs there is a clear separation between the connection-object and the schema-object(s), and for good reason : schema-changes are few and far between - requests/connections are numerous and rapid - it makes no sense tying them together like that... It's a poor design-choice, IMHO. Of course, the problem with this approach is that you couldn't dynamically change any attributes of the table or its fields (e.g., .readable and .writable) at request time, because that would effect other requests as well. I don't know that needing to define a per-request readable/writable is such a common use-case - or else I don't fully understand what you are alluding to... Are these definitions for security that are modified based on auth-definitions, after being cross-referenced with the request/session-user? If so, I guess they would have to be re-set automatically by the DAL object on each request, but that doesn't mean the entire-schema needs to be re-generated - the auth-definitions are already in the database anyways, and this means it's not a schema-related issue - it's just data that got bolted-onto the schema-objects for convenience... If it is taken from the database anyways (or even if it's caches), the bolted-on variables can be reset on each request in a thread-safe kind of way - though that may require further thinking... -- 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] Re: DAL usage
I don't know that needing to define a per-request readable/writable is such a common use-case - or else I don't fully understand what you are alluding to... Sometimes you want to show/hide particular fields in a form, grid, etc. depending on some condition, so you set the readable and writable attributes dynamically in the controller. Also, default, represent, and compute attributes as well as validators sometimes use request specific data. If so, I guess they would have to be re-set automatically by the DAL object on each request, It's not just a matter of resetting. If there is only a single fixed instance of an object that gets imported from a module, any change to an attribute during a request will persist (and affect other simultaneous requests).
