[web2py] GAE: insert using key_name
Hi,
In GAE it's possibe to supply a key_name when you insert an entity. This
is a string that you can then use as an id to efficiently fetch an entity
from db.
(
https://developers.google.com/appengine/docs/python/datastore/entities#Python_Kinds_and_identifiers
)
I would like to be able to do this using web2py. I could also choose to use
the GAE API directly to do this but then a could not make use thing like
calculated Fields etc in my web2py tables.
I made the following modification to the GoogleDatastoreAdapter insert()
function:
def insert(self,table,fields):
dfields=dict((f.name,self.represent(v,f.type)) for f,v in fields)
# table._db['_lastsql'] = self._insert(table,fields)
# Field name 'gae_key_name' can be used insert using key_name for
both DB and NDB.
keyname = None
*if 'gae_key_name' in dfields:keyname =
dfields['gae_key_name']if self.use_ndb:
dfields['id'] = dfields.pop('gae_key_name')else:
dfields['key_name'] = dfields.pop('gae_key_name')*
tmp = table._tableobj(**dfields)
tmp.put()
key = tmp.key if self.use_ndb else tmp.key()
rid = Reference(key.id())
(rid._table, rid._record, rid._gaekey) = (table, None, key)
return rid
Now one can insert using a field name 'gae_key_name'.
DB and NDB expect different parameter names for the model constructors to
supply a key_name. 'key_name vs 'id''.
Now the only problem is that _listify() in Table required that all fields
are defined in the Table.
We can now choose to define a Field gae_key_name in every Table that we
want to use this feature for.
Another option is to modify the _listify function a bit to accomodate this:
def _listify(self,fields,update=False):
new_fields = {} # format: new_fields[name] = (field,value)
# store all fields passed as input in new_fields
# 'gae_key_name' is GAE specific and should not be defined in the
table.
for name in fields:
if not name in self.fields:
*if name not in ['id', 'gae_key_name']:raise
SyntaxError('Field %s does not belong to the table'
% name)if name == 'gae_key_name':#
Create stub Field for 'gae_key_name' so it can be included
# without being defined in the model.field =
Field('gae_key_name', 'string')
new_fields['gae_key_name'] = field, fields['gae_key_name']*
else:
field = self[name]
value = fields[name]
if field.filter_in:
value = field.filter_in(value)
new_fields[name] = (field,value)
The last option feels a bit hacky but removes the requirement to define a
Field 'gae_key_name' in every Table.
What to you think?
I attached a patch that includes both changes.
Regards,
Quint

I have a question that hopefully can be answered easily and maybe I am
overlooking something.
I have the smart grid working well however i want to display a reference of
a reference eg
Vehicle Model Make
Please bare in mind i am using a legacy db
Model

Field('ModelID','id'),
Field('MakeID','reference tblmake'),
format=%(Model)s,
migrate=False)
#
db.define_table('tblvehicles',
Field('VehicleID','id'),
Field('Registration','string'),
Field('Driver','string'),
Field('Model','reference tblmodels'),
migrate=False)
Controller
vehiclefields = [db.tblvehicles.Registration, db.tblvehicles.Driver,
db.tblvehicles.Model]
vehiclelinks = [lambda row: A('View
Post',_href=URL(search,test,args=[row.VehicleID]))]
vehicles = SQLFORM.smartgrid(db.tblvehicles, orderby=VehicleID Desc,
fields=vehiclefields, formname=vehiclegrid,
details=False, editable=False,
deletable=False,links=vehiclelinks, linked_tables=False)
I would like to display the db.tblmake.Make field
How can I do this?
Can I do this?
I have tried adding various combinations but with no luck
Any help would be greatly appreciated

[web2py] Re: Microsoft SQL Server Migrate Trying to Create New Table instead of Editing Old One
For future reference, verifying that this can be fixed using the
fake_migrate feature (
http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Fixing-broken-migrations
)
Summary of steps:
1. Set your model in define_table to the old model that matches existing
database
2. Set fake_migrate to True in define_table(..., migrate=True,
fake_migrate=True)
3. Run your app - this will create the migrate files
4. Remove the fake_migrate argument from define_table
5. Run your app again, this will do a migrate with an ALTER instead of a
CREATE

So, in theory, will the following process fix the issue?
1. Start web2py with old DAL definitions and migrate = True. This should
create the .table files as the old structure
2. Then change the DAL to reflect the new database structure, migrate
still = True
3. Restart web2py and my tables should get migrated?

[web2py] Re: GAE: insert using key_name
Yes,
Your post reminds me, I forgot something. I thought that when a key_name is
used, it could simply return that as an id.
But if you say that DAL requires that it returns an integer id, than yes,
that would break it.
When you use a key_name, the records do not have an numeric id.
But does that mean you should not allow it to be inserted that way?
Nothing restricts users from operating (using web2py api) on rows inserted
with GAE api
dfields=dict((f.name,self.represent(v,f.type)) for f,v in fields)
# table._db['_lastsql'] = self._insert(table,fields)
#quint
keyname = None
if 'gae_key_name' in dfields:
keyname = dfields['gae_key_name']
if self.use_ndb:
dfields['id'] = dfields.pop('gae_key_name')

Maybe the best answer is to change Row so that it always holds the full

which implements this strategy of testing keys for dicts within dicts. Our
case is a little simpler since we never recurse more than one level deep.
def _finditem(obj, key):
if key in obj: return obj[key]
for k, v in obj.items():

item = _finditem(v, key)
if item is not None:

This has the advantage of working with existing code and preserving as
much information as possible in the Row object. I have a feeling this
could make the internals of web2py a good deal more consistent. Less
testing for special cases is always good!

The Rows.find() method does the following:
for row in self:

In a Rows object, there is self.records, which is a list of Row objects.
Each Row object has at least one top-level key with the table name, and the
record is stored in the value associated with that key:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
When .find() is called on a Rows object with compact=True, the __iter__
method (called by the for row in self loop) returns a transformed version
of each Row object, removing the top-level table key:
Row {'first_name': 'Bob', 'last_name': 'Smith'}
I believe this is an unnecessary transformation, and it is what is
subsequently causing the .render() method to fail (the .render() method
expects the top-level table key to be there, whether or not compact=True).
I propose the following change to .find():
for i, row in enumerate(self):
if f(row):
if a=k: records.append(self.records[i])
k += 1
if k==b: break
The above code appends self.records[i] instead of row, which preserves
the original Row objects instead of including transformed objects. Anyone
see any problems with that change?
Also, is there any reason all of the Rows methods (i.e., find, exclude,
__and__, __or__) should not be preserving the compact attribute of the
original Rows object? Perhaps we should change them all to do so. (Note,
this is a separate issue unrelated to the above problem with .find() and
.render().)

Aside from this issue, perhaps the various Rows methods should preserve

For example. if you sort the Rows, it leaves compact=True. Ditto,
if you use extract or find on the Rows object. The and |

you
can't use any of these operators on the Rows object and then use render

It is a simple change to add the preservation of the compact flag

Other than coming up with a completely parallel set of methods, which
leave compact set the way it came in, I can't think of another approach

Nothing restricts users from operating (using web2py api) on rows inserted with GAE api There's no restriction on the use of the datastore, since it is not a service reserved for web2py apps, although I belive storing records without id assignment would be restrictive for apps (and I doubt it will be actually compatible at all, with the exception of the keyed tables mentioned before, in case it is supported). -- 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.

I tried 'python scheduler.py -h' to get more information. it blew up with an error no module named simplejson.

[web2py] Re: Rows.compact and other Rows methods
This is an interesting idea. Instead of bothering with the compact
attribute, we could make it so any Row object automatically works like a
compact Row whenever it includes only one top-level key. So, if you have:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
you could do either row.person.first_name or row.first_name, regardless of
the value of the compact attribute. The problem, though, is what happens
if there is a field name that is the same as the table name. In that case,
we would have to make the default to return either the full sub-record
associated with the table, or just the field within the table, but neither
approach would be fully backward compatible.
I suppose we could keep using the compact attribute, and simply pass it
to the Row object, so the Row object itself knows whether it is compact or
not. This would also be necessary for the Row.as_dict and related methods
to remain backward compatible. But then the Row object needs to be able to
hold a private attribute (e.g., __compact).
Thoughts on this?

Maybe the best answer is to change Row so that it always holds the full
set of keys (table:field) and change the __getitem__ method to look up the
key recursively if only one part is provided. Here is a sample method
which implements this strategy of testing keys for dicts within dicts. Our
case is a little simpler since we never recurse more than one level deep.
def _finditem(obj, key):
if key in obj: return obj[key]
for k, v in obj.items():
if isinstance(v,dict):
item = _finditem(v, key)
if item is not None:
return item
This has the advantage of working with existing code and preserving as
much information as possible in the Row object. I have a feeling this
could make the internals of web2py a good deal more consistent. Less
testing for special cases is always good!

The Rows.find() method does the following:
for row in self:
if f(row):
if a=k: records.append(row)
k += 1
if k==b: break
In a Rows object, there is self.records, which is a list of Row
objects. Each Row object has at least one top-level key with the table
name, and the record is stored in the value associated with that key:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
When .find() is called on a Rows object with compact=True, the __iter__
method (called by the for row in self loop) returns a transformed
version
of each Row object, removing the top-level table key:
Row {'first_name': 'Bob', 'last_name': 'Smith'}
I believe this is an unnecessary transformation, and it is what is
subsequently causing the .render() method to fail (the .render() method
expects the top-level table key to be there, whether or not compact=True).
I propose the following change to .find():
for i, row in enumerate(self):
if f(row):
if a=k: records.append(self.records[i])
k += 1
if k==b: break
The above code appends self.records[i] instead of row, which preserves
the original Row objects instead of including transformed objects. Anyone
see any problems with that change?
Also, is there any reason all of the Rows methods (i.e., find, exclude,
__and__, __or__) should not be preserving the compact attribute of the
original Rows object? Perhaps we should change them all to do so. (Note,
this is a separate issue unrelated to the above problem with .find() and
.render().)

.render() works fine on Rows objects with compact=True, and it also

The
only problem is with the results of .find() operations when the original
Rows object has compact=True. The problem is that the .find() method
modifies the Row objects in self.records when compact=True, which it
probably should not due.
Aside from this issue, perhaps the various Rows methods should
preserve the compact attribute -- not sure why they don't.
Forwarding to the developers list for discussion.

work and well, none of it f***ing would. Yesterday I brewed an extra strong
pot of coffee and cranked this out.
Some of the code i would like review on, I am not sure how to properly
check for if there was an uploaded file or not, i have that weird is in
then len() 0 but i don't think it's the best.

[web2py] Scheduler repeat time drift
Is there any way to keep the time at which recurring tasks run from drifting? I've got several daily tasks that over time go from running at say 10am to 10:30am - it seems like each consecutive run is 20 seconds or so behind the previous day's. Is this simply a matter of the next execution time being set based on the ending time of the current run rather than the starting time? If I want to better enforce running at a certain time daily do I need to resort to having a maintenance task run say once a week and reset the next run time of the daily tasks so they don't drift too far? I suppose that this isn't too much of an issue for tasks that run on a more regular basis like once a minute to process constantly updated queues, but for things that you want to run at a certain set time it's a bit annoying.

[web2py] Re: [web2py-dev] Rows.compact and other Rows methods

not every time a row column is accessed.

Row object has at least one top-level key with the table name, and the record
is stored in the value associated with that key:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
When .find() is called on a Rows object with compact=True, the __iter__
method (called by the for row in self loop) returns a transformed version
of each Row object, removing the top-level table key:
Row {'first_name': 'Bob', 'last_name': 'Smith'}
I believe this is an unnecessary transformation, and it is what is
subsequently causing the .render() method to fail (the .render() method
expects the top-level table key to be there, whether or not compact=True). I
propose the following change to .find():
for i, row in enumerate(self):
if f(row):
if a=k: records.append(self.records[i])
k += 1
if k==b: break
The above code appends self.records[i] instead of row, which preserves the
original Row objects instead of including transformed objects. Anyone see any
problems with that change?
Also, is there any reason all of the Rows methods (i.e., find, exclude,
__and__, __or__) should not be preserving the compact attribute of the
original Rows object? Perhaps we should change them all to do so. (Note, this
is a separate issue unrelated to the above problem with .find() and

I've been experimenting with the render method of the Rows class, and I am

its value set to compact=False to work properly with render(). It isn't a
problem if the Rows object is used directly without any operators, but I
discovered that many, if not most, Rows methods do not preserve the compact
setting.
For example. if you sort the Rows, it leaves compact=True. Ditto, if you
use extract or find on the Rows object. The and | operators also
set the compact variable to True. The upshot is that you can't use any of
these operators on the Rows object and then use render on the resulting
object.
It is a simple change to add the preservation of the compact flag during
any of these steps, but I'm unsure if this will break existing code. Other
than coming up with a completely parallel set of methods, which leave compact
set the way it came in, I can't think of another approach will be provably
backwards-compatible.
Here is an example:
[web2py] Re: [web2py-dev] Rows.compact and other Rows methods
This would be slow and confusing. What if there is a table in the join called
first_name? What if both tables in a join have a column first_name?

This is an interesting idea. Instead of bothering with the compact
attribute, we could make it so any Row object automatically works like a
compact Row whenever it includes only one top-level key. So, if you have:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
you could do either row.person.first_name or row.first_name, regardless of
the value of the compact attribute. The problem, though, is what happens if
there is a field name that is the same as the table name. In that case, we
would have to make the default to return either the full sub-record
associated with the table, or just the field within the table, but neither
approach would be fully backward compatible.
I suppose we could keep using the compact attribute, and simply pass it to
the Row object, so the Row object itself knows whether it is compact or not.
This would also be necessary for the Row.as_dict and related methods to
remain backward compatible. But then the Row object needs to be able to hold
a private attribute (e.g., __compact).
Thoughts on this?

[web2py] Validating list:string fields
Hello,
I'm trying to validate a list:string field with is_alphanumeric and
is_length - trying to ensure that names are no longer than 6 alphanumeric
characters in length. (I'm running web2py 2.8.1 in ubuntu 12.04)
view:
liSample name *: {{=form.custom.widget.sample_name}}/li
controller:
form = SQLFORM(db.register,fields=[..,'sample_name',...])
if form.validate(onvalidation=validate_sample_name):
form.vars.id = db.register.insert(**dict(form.vars))
response.flash = 'Reg saved.'
redirect(URL('samples', 'default', 'index'))
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
model:
db.define_table(
register,
.
Field('sample_name','list:string'),
)
def validate_sample_name(form):
for sample in form.vars.sample_name:
out,ers = IS_ALPHANUMERIC()(sample) and
IS_LENGTH(maxsize=6)('sample')
if ers:
form.errors.sample_name = ers
The above does check for alphanumeric characters but doesn't seem to check
for the length of each sample name.
Am I doing something wrong?
Many thanks.

[web2py] Re: pyfilesystem support (store uploads in S3)
Hey guys! I know this topic is old, but here it's *working great* with
mysql or sqlite on web2py 2.7.4.
Just install:
pip install fs
Then on model:
import fs.s3fs
myfs = fs.s3fs.S3FS(bucket, prefix, aws_access_key, aws_secret_key)
db.define_table('image',Field('image','upload',uploadfs = myfs))
I'm using ubuntu 12.04 amd64 with python 2.7.3 virtualenv.
Thx for your help!

Now all your uploaded files will go on S3.
Here is a list of supported filesystems:

- needs testing. I have tested with OSFS and I am confident it works
- I do not think with will work on GAE, should be tested
- uploadfolder and uploadseparate are ignored when uploadfs is specified
(this should be changed, any takers?)
Should be possible to wrap myfs into an encryption layer but I have not
done it yet.
We may want a more comprehensive strategy and allow every web2py file
(including apps, sessions, tickets, etc) to go into a pyfilesystem. Is this
necessary? On linux one can mount filesystems in a folder anyway. Is this
more trouble than it is worth?

Maybe the best answer is to change Row so that it always holds the full

which implements this strategy of testing keys for dicts within dicts. Our
case is a little simpler since we never recurse more than one level deep.
def _finditem(obj, key):
if key in obj: return obj[key]
for k, v in obj.items():
if isinstance(v,dict):
item = _finditem(v, key)
if item is not None:

This has the advantage of working with existing code and preserving as
much information as possible in the Row object. I have a feeling this
could make the internals of web2py a good deal more consistent. Less
testing for special cases is always good!

The Rows.find() method does the following:
for row in self:
if f(row):
if a=k: records.append(row)
k += 1
if k==b: break
In a Rows object, there is self.records, which is a list of Row
objects. Each Row object has at least one top-level key with the table
name, and the record is stored in the value associated with that key:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
When .find() is called on a Rows object with compact=True, the __iter__
method (called by the for row in self loop) returns a transformed
version
of each Row object, removing the top-level table key:
Row {'first_name': 'Bob', 'last_name': 'Smith'}
I believe this is an unnecessary transformation, and it is what is
subsequently causing the .render() method to fail (the .render() method
expects the top-level table key to be there, whether or not compact=True).
I propose the following change to .find():
for i, row in enumerate(self):
if f(row):
if a=k: records.append(self.records[i])
k += 1
if k==b: break
The above code appends self.records[i] instead of row, which preserves
the original Row objects instead of including transformed objects. Anyone
see any problems with that change?
Also, is there any reason all of the Rows methods (i.e., find, exclude,
__and__, __or__) should not be preserving the compact attribute of the
original Rows object? Perhaps we should change them all to do so. (Note,
this is a separate issue unrelated to the above problem with .find() and
.render().)

.render() works fine on Rows objects with compact=True, and it also

The
only problem is with the results of .find() operations when the original
Rows object has compact=True. The problem is that the .find() method
modifies the Row objects in self.records when compact=True, which it
probably should not due.
Aside from this issue, perhaps the various Rows methods should
preserve the compact attribute -- not sure why they don't.
Forwarding to the developers list for discussion.

For example. if you sort the Rows, it leaves compact=True. Ditto,

[web2py] Re: Validating list:string fields
For a list:-type field, I think you can only use IS_IN_SET(...,
multiple=True), IS_IN_DB(..., multiple=True), IS_NOT_EMPTY(), and
IS_LIST_OF(), no?
IS_LIST_OF() takes only a single additional validator, so to apply multiple
validators using it, you would probably have to create a custom validator
that applies multiple validators.

Maybe the best answer is to change Row so that it always holds the full

which implements this strategy of testing keys for dicts within dicts. Our
case is a little simpler since we never recurse more than one level deep.
def _finditem(obj, key):
if key in obj: return obj[key]
for k, v in obj.items():
if isinstance(v,dict):
item = _finditem(v, key)
if item is not None:

This has the advantage of working with existing code and preserving as
much information as possible in the Row object. I have a feeling this
could make the internals of web2py a good deal more consistent. Less
testing for special cases is always good!

The Rows.find() method does the following:
for row in self:
if f(row):
if a=k: records.append(row)
k += 1
if k==b: break
In a Rows object, there is self.records, which is a list of Row
objects. Each Row object has at least one top-level key with the table
name, and the record is stored in the value associated with that key:
Row {'person': {'first_name': 'Bob', 'last_name': 'Smith'}}
When .find() is called on a Rows object with compact=True, the
__iter__ method (called by the for row in self loop) returns a
transformed version of each Row object, removing the top-level table key:
Row {'first_name': 'Bob', 'last_name': 'Smith'}
I believe this is an unnecessary transformation, and it is what is
subsequently causing the .render() method to fail (the .render() method
expects the top-level table key to be there, whether or not
compact=True).
I propose the following change to .find():
for i, row in enumerate(self):
if f(row):
if a=k: records.append(self.records[i])
k += 1
if k==b: break
The above code appends self.records[i] instead of row, which preserves
the original Row objects instead of including transformed objects. Anyone
see any problems with that change?
Also, is there any reason all of the Rows methods (i.e., find,
exclude, __and__, __or__) should not be preserving the compact
attribute
of the original Rows object? Perhaps we should change them all to do so.
(Note, this is a separate issue unrelated to the above problem with
.find()
and .render().)

The
only problem is with the results of .find() operations when the original
Rows object has compact=True. The problem is that the .find() method
modifies the Row objects in self.records when compact=True, which it
probably should not due.
Aside from this issue, perhaps the various Rows methods should
preserve the compact attribute -- not sure why they don't.
Forwarding to the developers list for discussion.

It isn't a problem if the Rows object is used directly without any

preserve the compact setting.
For example. if you sort the Rows, it leaves compact=True. Ditto,
if you use extract or find on the Rows object. The and |

[web2py] Re: Scheduler repeat time drift
I don't exactly get how you scheduled the tasks and how are you expecting them to run. If you schedule a task to start at 10am and set a period of 24*60*60, the task will be requeued to be executed at 10am. As the book says, *The time period is not calculated between the END of the first round and the START of the next, but from the START time of the first round to the START time of the next cycle)* On Wednesday, January 8, 2014 5:10:38 PM UTC+1, Brian M wrote: Is there any way to keep the time at which recurring tasks run from drifting? I've got several daily tasks that over time go from running at say 10am to 10:30am - it seems like each consecutive run is 20 seconds or so behind the previous day's. Is this simply a matter of the next execution time being set based on the ending time of the current run rather than the starting time? If I want to better enforce running at a certain time daily do I need to resort to having a maintenance task run say once a week and reset the next run time of the daily tasks so they don't drift too far? I suppose that this isn't too much of an issue for tasks that run on a more regular basis like once a minute to process constantly updated queues, but for things that you want to run at a certain set time it's a bit annoying.

I've got it scheduled to repeat every 86400 seconds (24*60*60) so once a day. I thought that it was supposed to keep the same start time like the book says but it has definitely been drifting - part of the task that's queued logs to a DB and I can see the timestamps there consistently drifting ~20 seconds later each day. I had another task originally setup to send out a daily email at 9AM and it's drifted to going out around 9:32AM over the last several months.

I've got several daily tasks that over time go from running at say 10am to 10:30am - it seems like each consecutive run is 20 seconds or so behind the previous day's. Is this simply a matter of the next execution time being set based on the ending time of the current run rather than the starting time? If I want to better enforce running at a certain time daily do I need to resort to having a maintenance task run say once a week and reset the next run time of the daily tasks so they don't drift too far? I suppose that this isn't too much of an issue for tasks that run on a more regular basis like once a minute to process constantly updated queues, but for things that you want to run at a certain set time it's a bit annoying.

[web2py] Re: GAE: insert using key_name
How about adding support in dal.py for the following:
# processes the field input and add defaults, computes, etc. (does not make
actual insertion).
values = db._insert(spam=alot, ...)
{spam: alot, ...}
So one can use the output for storing named keys (with app specific logic
or maybe plugin for extended datastore functions).
AFAIK, the patch is trivial (it would need adding a _insert adapter method
like the case of mongodb or imap)

[web2py] Best practices with sessions
Hello everyone, I'm trying to implement the web2py recipes to improve the efficiency and security of my backend. I'm beggining with sessions and I have a couple of doubts: - My site is over SSL and has user authentication, so I guess I should secure my sessions. The recipe sais In your applications, if they require authentication, you should make the session cookies secure with:session.secure(), but, where should I put that code? - The number of session files of my server is growing quickly so I should use the sessions2trash.py script, but, how should I use that script? Should I create a cron task in my server that execute each day something like this python web2py.py -S app -M -R scripts/sessions2trash.py -A -o -x 3600 -f?

[web2py] Sharing fields across different tables in models?
If we have a table full of products, but some products use slightly
different fields, how should this be represented?
For example, if I sell clothing and furniture:
clothing and furniture share these fields:
- price
- description
- stock
- name
clothing have these special fields:
- material/fabric
- size
furniture have these special fields:
- weight
Then, would this be a good way to handle it:
db.define_tables('product_fields',
Field('price', 'double'),
Field('description', 'string'),
Field('stock', 'integer),
Field('name', 'string'))
db.define_tables('clothing_product',
Field('material_fabric', 'string'),
Field('size', 'string'),
Field('product_field', 'reference product_fields'))
db.define_tables('furniture_product',
Field('weight', 'double'),
Field('product_field', 'reference product_fields'))
The other way I can think of would be to have only two tables;
'clothing_product' and 'furniture_product' but have the shared fields be
replicated in both tables.
If I use the first approach, how would I resolve these problems:
1) How do I query all products at once, both clothing and furniture(and
more if I add different products in the future)?
2) Because the tables are split for the products (ie, a clothing product
stores its data in 'clothing_product' and 'product_fields' tables), how do
I build forms for both tables and save them in one html page? I looked
here: http://www.web2py.com/book/default/chapter/07#Multiple-forms-per-page but
that has two submit buttons that submit two independent forms. The only
solution I can think of is to build my forms manually and then grab the
values to insert into the db.
3) if I want to associate a product with a category, how should this be
linked? For example:
db.define_tables('categories',
Field('category_name', 'string'))
db.define_tables('categories_and_products',# Many to many relationship
Field('category_id', 'reference categories'),
Field('product_id', 'reference ???')) # what table should I
reference here ???

[web2py] Re: Set Field Type Dynamically
There's no need to change the field type. If you don't want to display the reference fields in the grid at all, just set the readable attribute to False. You can also pass a list of fields to the grid to display -- other fields will be excluded. If you do want to include the reference fields but want them to simply show the stored id values rather than doing recursive selects to retrieve values from the referenced table, just set db.tablename.field.represent = None.

[web2py] Re: Sharing fields across different tables in models?
just a suggestion, why not create the table for category.
e.g.
db.define_tables('category',
Field('name', 'string') )
db.define_tables('product',
Field('price', 'double'),
Field('description', 'string'),
Field('stock', 'integer),
Field('name', 'string')
Field('material_fabric', 'string'),
Field('size', 'string'),
Field('weight', 'double'),
Field('category', 'reference category') )
then just use conditional method in view using jquery to show the field
that match with category.
best regards,
stifan
