[web2py] Re: How to add more buttons to form that submits form to different actions ...
I'm trying to find out nice solution for situation where the user makes some basic selection on form and then I have to load some aditional data from server. For example when user makes selection of manager name using combo box on form then I need to send data to server to load some aditional information based on his selection . So its just simple roundtrip to server but to specific action based on what user just did.(and I can have a few such selection-post/refresh actions on the form) Is there a way you use for such scenarios?
[web2py] Database constraints or Web2py validators
I have several tables where there should only be one possible combination of two uuid-fields per table (mostly many to many links). I have created 'unique' constraints for those fields in Postgresql so the database would not accept any inserts or edits which violates that constraint. I use that in combination with 'try:.. except:' to insert data. Can DAL be used in a way for this? As far as I understand the IS_NOT_IN_DB validators that it is working on form-level and not on database level and I am not sure whether it can be used for a combination of fields (unless I do it with a computed field - which will use up a lot of extra resources).

Re: [web2py] Re: Tag handling suggestions
In my opinion I'll discard option number 1 if you are not running on GAE. Because is not a true SQL, is quite awfull indeed, bring it by nosql gae. But it's all depends on the amount of records. 2011/10/10 Bruno Rocha rochacbr...@gmail.com I like this, and it is really smarter than list:string option, but, imagine a blog where users include tags in an INPUT text field, this will be more difficult to store tags in other table (you can do using ajax or building a checkbox list of tags) but it is easy just to let the user put tags in a text field comma separated or space sepated, then split and store in list:string field. -- http://martin.tecnodoc.com.ar

[web2py] Static forms

[web2py] Re: Tag handling suggestions
How does choosing option 1 -- option 3 affect building a UI ? It seems to me that option 1 can be used as-is in an SQLFORM.grid containing other fields, whereas option 3 might require a separate SQLFORM.grid to manage the correspondence tags-items? If this is just me not understanding all possibilities of SQLFORM.grid, then please elaborate.
[web2py] Re: Static forms
Same as usual -- you have to create a FORM (or SQLFORM) object in the controller and use form.accepts (or the newer form.process). You can create the form manually in HTML and just make sure you include the _formname hidden field (see http://web2py.com/book/default/chapter/07#SQLFORM-in-HTML), though that won't involve a _formkey and therefore won't provide CSRF protection. A better way is probably to use SQLFORM.factory and use the method described here (http://web2py.com/book/default/chapter/07#Custom-forms) to customize the HTML.

That will make sure field2 is unique among the set of records where field1

[web2py] Re: two SQLFORM.grid in one view?
Maybe useful for readers in the future: Using multiple grids in one view is not supported, and the problems won't be fixed. (workaround: e.g. use iframes, or design a better UI that doesn't need two grids in one view ;) )
[web2py] Re: two SQLFORM.grid in one view?
Let me explain and clarify.
A grid can display multiple actions (select/edit/view/update etc...)
it discriminates this from the URL. Different grid actions have
different URLs. This is a feature. This allows you to reference a
particular page in a grid using the URL and send for example a link to
a friend.
Fixing would mean removing the ability to link a grid action (for
example results of a search).
If you have two grids in one page you can no longer use the URL to
determine what each of the two views should be displaying unless you
*hide* the URL.
This can be done by putting the grid into an iframe or loading the
grid via ajax with{{=LOAD('')}}

also slightly frustrating is that the add/view/edit pass the table name so you can generate output based on that. However the paginate buttons do not pass the table name. So if you have a controller that dynamically creates grid parameters depending on the table then this does not work with paginate.

Problem with Datatables, is that it not supports the export button to work on more then once instance of datatables init per page if you choose to put your tables into tabs with jQuery UI tabs... So you have to choose between export feature or put your differents tables in differents tabs... I was really happy to see that Web2py was implementing nice grid and thought that it will support any number of instance per page. I have to display on the same page more then one table for related data that not share the same amount of columns... I would prefer to not have more pages because data are directly related and adding entry in the menu will bring rapidly the app to be difficult to navigate (there is already a lot of entry in the menu). Hope the problems describes here could find a solution soon...

[web2py] Re: table without id
Hi,
I have been able to access legacy databases that don't have an id
field. In the following example 'pointnumber' is the primary key, and
is unique. I was able to read values from this table with DAL. I used
the following model:
db2.define_table('statuspoint',
Field('pointnumber','integer'),
Field('pointname','string'),
Field('pointaccessarea','integer'),
Field('station','integer'),
Field('statefeatures','integer'),
Field('indication','integer'),
primarykey=['pointnumber'],
)
Some parts of web2py(such as SQLFORM.grid) appear to require the 'id'.
To allow this, I created a view in my database(mysql) to rename the
pointnumber field to id.
CREATE VIEW view_statuspoint AS
SELECT pointnumber id,pointname,pointaccessarea,
station,statefeatures,indication
from statuspoint;
The following model uses the view:
db2.define_table('view_statuspoint',
Field('id','integer'),
Field('pointname','string'),
Field('pointaccessarea','integer'),
Field('station','integer'),
Field('statefeatures','integer'),
Field('indication','integer'),
Field('dog_assignment_fko','integer'),
migrate=False
)
This allowed me to create a form with SQLFORM.grid and to update
records. That's all I've tested.

How should I handle this?
Re: [web2py] Re: db events trigger
I suggested it 2 years ago. I'll be happy if it come true someday, in web2py.
I see it as database triggers: before_event after_event. I.e:
before_insert, after_insert. Event can be: insert, update, delete,
query.
before_insert receives values that will be inserted on database. It
is the last chance to modify, check some value or make run some
routine before register is inserted.
after_insert receives values just stored there.
before_update receives data stored on the database, before the
record is updated. As before_insert, this is a last chance event.
after_update receives data contents after the update took place.
before_delete receives data stored on the database. As
before_update does. Also, it's a last chance event.
after_delete receives same data, but after register was deleted.
before and after query I don't see as important. Web2py already
has virtual and computed fields. But would be nice to log accesses to
some table.
I worked with these triggers on Sybase, many years ago. But I remember
how it was nice to make stored procedures and triggers counting on
these events (except query events. I just saw it on Oracle),
guaranteeing db integrity.

As I said, the problem is not the names or when they should be called.
The problem is. What should be input and the output of each of these
functions?

I suggested it 2 years ago. I'll be happy if it come true someday, in web2py.
I see it as database triggers: before_event after_event. I.e:
before_insert, after_insert. Event can be: insert, update, delete,
query.
before_insert receives values that will be inserted on database. It
is the last chance to modify, check some value or make run some
routine before register is inserted.
after_insert receives values just stored there.
before_update receives data stored on the database, before the
record is updated. As before_insert, this is a last chance event.
after_update receives data contents after the update took place.
before_delete receives data stored on the database. As
before_update does. Also, it's a last chance event.
after_delete receives same data, but after register was deleted.
before and after query I don't see as important. Web2py already
has virtual and computed fields. But would be nice to log accesses to
some table.
I worked with these triggers on Sybase, many years ago. But I remember
how it was nice to make stored procedures and triggers counting on
these events (except query events. I just saw it on Oracle),
guaranteeing db integrity.

Consider the case of preupdate and onupdate.
db(db.person.age18).update(can_drink=True)
What information should be passed to preupdate and update? tablename?
query? {'can_drink':True}? Number of affected records? Should there be
one onselect per table? We do not want to call onupdate for every
table, do we (performance issues)?
What about?
db(db.person.id=2).update(can_drink=True)
What about
db(db.person).select(left=db.dog.on(db.dog.owner==db.person.id),limitby=(0,
1))
What should we pass to onselect? query? left? limitby? all arguments?
number of returned records? returned records? In this case we cannot
pass one table because because more than one table may be involved.
Every one of those callbacks would need a different signature. It
would not be obvious and I am not sure people would agree.
I do not oppose to this. I just want to hear more from you.

Would be nice to have some global events in web2py workflow. I can imagine
some useful hooks:
workflow global events:
onrequest # before the execution of action/model
prerender # after the execution of action/model but before the view
rendering
onrender # after the view render but before the output
onresponse # after all the request process finished.
DAL global events:
preselect - onselect
preinsert - oninsert
preupdate - onupdate
predelete - ondelete
ASPnet has some usefull event system (oninit, onload, pageload etc..)
I dont even know if it is possible to trigger all of them in web2py and how
can it cost. but would be nice to have it.

Hi,
is there a way to trigger some functions on database eventes, for

[web2py] Re: DAL level access to GAE entities by named key
I'm getting nothing (None). If the intention was to having it work this way (by passing key as id) I'll have a look at the DAL code more closely. Maybe something affects the key outside of the select_raw function. Have this ever worked for you?

What should be input and the output of each of these functions? Whenever I'm in a problem with a full stack web framework, I think to myself what would cakePHP do? OK, that's really NOT the way you should think, but they did some job on the input and output of some of these functions (they don't have migrates, so the migration events I'd like to see, are not there), and we should learn from it: afterDelete( ) - cake API allows you delete only one row at the time, and it's data is part of the object delete is ran upon (like our delete_record() method). Retuens a void, but the object stil contain the deleted record. afterFind( $results, $primary = false ) - I'm not sure what primary means, but the results, contain a list of all results. Returns a list of modified results. afterSave( $created ) - The created row. This method runs on create and on update. When I worked with it, I really wanted 2 seperate functions. returns void. beforeDelete( $cascade = true ) - Again, has the data of the deleted record. The cascade is like to web2py recursive deletes. Returns a boolean that suggests wether delete should continue. beforeFind( $queryData ) = That's a bit more problematic for us. cakePHP has an array of all the joins and conditions, that can be used in $queryData. I'm not sure web2py has one we can create. But... what do I know? returns either boolean or modified query. beforeSave( $options ) - I have no idea what the options are, and I'm not sure I'm keen on exploring it. Returns true if save should continue, false if not. beforeValidate( $options ) - same as beforeSave beforeFilter and afterFilter - Well... I'm not sure how relevant it is for our case. This is where you find user auth logic. beforeRender() - This function is called, so you can change some vars before a view is presented. This one applies on a paticular controller (can be applied to all controllers using inharitance, but that's the way cake works, not really relevat to web2py). The cake API is not 100% relevant to web2py, but we can use it to get some idea how others solved it.
