Can you add a custom field/column to a SQLFORM.grid?
You can use the "links" argument: grid = SQLFORM.grid(query, fields=[db.table1.total, db.table2.count], links=[dict(header='Total - Count', body=lambda r: r.table1.total - r.table2.count)]) By default, all "links" columns appear on the right. You can change that by setting the "links_placement" argument to either "left" or "both"....

Web2py - Insert Record in Second Tabel on Registration
If you started with the scaffolding app, in the default.py controller, you probably have a function like: def user(): return dict(form=auth()) Calling the auth object handles processing for all Auth actions (the particular action is determined based on the first URL arg after /default/user -- so, /default/user/register triggers the registration...
Problems with ajax and session variable in Web2Py
javascript,python,ajax,session,web2py

web2py: module function that behaves normally in shell fails browser mode
It looks like you're just trying to remove None values from a dictionary, so instead, why not just create a function to do that: def remove_none(d): [d.pop(key) for key in d.keys() if d[key] is None] Then you can do: col = remove_none(dict(field=attr.columns.tolist(), title=None, width=None, attributes=None)) Or if you want to...

Web2py Views & URL Patterns
The best approach depends on exactly what needs to differ in the view based on the different categories. Let's say you have a URL like /myapp/default/index/Small/Happy. In the index function, you could do something like: def index(): size = request.args(0) emotion = request.args(1) data = [code based on size and...
How do i print out a single row record

web2py: how to customize add.edit forms in SQLFORM.smartgrid?
python,model-view-controller,web,web2py
If you just want to change the form widgets used for particular fields, you do not have to customize the create/update forms directly. Instead, you can just specify the appropriate validators and custom widgets: db.define_table('mytable', Field('field1', requires=IS_IN_SET(['a', 'b', 'c'])), Field('field2', requires=IS_IN_SET(['x', 'y', 'z'], multiple=True), widget=SQLFORM.widgets.checkboxes.widget)) The IS_IN_SET validator will automatically...

How to self-submit a web2py-component at change-event

Web2py: Limiting a dropdown value only to Logged in user
python,forms,validation,web2py
If the only email address allowed in this field is that of the currently logged in user, then maybe just set that as the default value and don't make the field writable: Field('coordinator', writable=False, default=auth.user.email if auth.user else None, update=auth.user.email if auth.user else None) However, a better approach might be...
Web2py - Custom Registration & Login Form in One

Multiple Validators for a single field
If you put the IS_IN_DB validator in a list, it will no longer generate the select widget. Instead of putting the validators in a list, you can use the _and argument: db.nsksystem.nskreleaseid.requires = IS_IN_DB(db, 'nskrelease.releaseid', _and=IS_NOT_IN_DB(db(db.nsksystem.nskmachinename == request.vars.nskmachinename), 'nsksystem.releaseid', error_message='Machine is already registered to the specified release.')) ...

Web2py with Multiple Controllers
When a function is needed from a controller, the whole controller must be read in; this will be faster the smaller the controller is. Whether it is enough of a difference to warrant the effort, that's what profiling is for. As for when to think about organizing controllers, the best...
web2py SQLFORM.grid () get field values on process
You can simply define the validator for one of the fields so it doesn't allow duplicates when the other field is also a duplicate, and then let the standard form validation process handle everything: db.define_table('mytable', Field('userid', 'reference auth_user'), Field('otherfield', requires=IS_NOT_IN_DB(db(db.mytable.userid == request.vars.userid), 'mytable.otherfield'))) Whenever a form is submitted, the IS_NOT_IN_DB...

DataTables Server-side Processing with web2py: how to access the parameters sent to the server
In web2py, variables from a POST request are in request.post_vars, variables from the query string are in request.get_vars, and both sets of variables are in request.vars. So, in your controller, you can access those variables via request.vars.iDisplayStart, request.vars.iDisplayLength, etc.
Conditional fields for a SQLFORM.factory in web2py
OK I figured it out. If you examine the page source on the SQLFORM.factory form, you notice that the ids given are "no_table_field1" and "no_table_field2". So, stealing borrowing the code from the JQuery & Ajax chapter of the web2py book, I add this to the end of the relevant view:...

web2py error: You might need to add explicit type casts

What is the use of Web2py's Field.Method?
It's basically a calculated db field. From the book: It is also possible to define method fields which are calculated on-demand, when called. For example: db.item.discounted_total = Field.Method(lambda row, discount=0.0: row.item.unit_pricerow.item.quantity(1.0-discount/100)) In this case row.discounted_total is not a value but a function. The function takes the same arguments as the...
Weird behavior with web2py DAL on table definition
Since db.customer is a keyed table (i.e., you have defined a primarykey attribute rather than relying on the default autoincrement integer ID field as the primary key), it can only be referenced by other keyed tables. Also, when creating reference fields for keyed tables, use the following syntax: Field('nric', 'reference...
