wrapping long text lengths in grid/smartgrid

[stefaan]

I was wondering about grid/smartgrid: currently we can use
maxtextlength=XXX to indicate the max length of a column. If the real
length is longer than XXX, the text is chopped at a suitable length
and "..." is added to it.
If you configure a long maxtextlength, at least with the default
template the column as displayed becomes very wide
Is it somehow possible instead to configure long maxtextlengths and
then have the text wrap at some column?

And related to this: Instead of having long maxtextlength and
wrapping, I could also enable the "View" button, but then I get to see
too many details (certain table columns I don't think are worth
displaying.) Can I customize the fields that are shown by clicking the
"View" button?

I still have no idea here.

Yes! By defining the database table Fields as writable=False and
readable=False.

grid should have a truncate parameter.

It seems that there is none at the moment.  I got

TypeError: grid() got an unexpected keyword argument 'truncate'

when trying

form = SQLFORM.grid(query, columns = columns,deletable = False,
                             orderby = db.akb_articles.title,  maxtextlength = 40,
                             truncate = 150
                            )

Here is the complete signature of grid method from source.... there is really no truncate param.

  def grid(query,

             fields=None,

             field_id=None,

             left=None,

             headers={},

             columns=None,

             orderby=None,

             searchable=True,

             sortable=True,

             paginate=20,

             deletable=True,

             editable=True,

             details=True,

             selectable=None,

             create=True,

             csv=True,

             links=None,

             upload = '<default>',

             args=[],

             user_signature = True,

             maxtextlengths={},

             maxtextlength=20,

             onvalidation=None,

             oncreate=None,

             onupdate=None, 

             ondelete=None,

             sorter_icons=('[^]','[v]'),

             ui = 'web2py',

             showbuttontext=True,

             _class="web2py_grid",             

             formname='web2py_grid',

            ):

maxtextlengths={'tablename.fieldname':20}, # per field
maxtextlength=20, # default

It would be nice to have a possibility to wrap text in a column.

I think if you specify a much longer maxtextlength, the text will ultimately wrap, but it may cause the column to be much wider than you want. Maybe all the th's and td's should include column-specific classes so we can use CSS to control the width and other attributes of each column.

Still no solution?

The grid now includes a <colgroup> element with <col> elements like the following:

<col id="tablename-fieldname" data-column="1">

So, you can use CSS rules to control the width of columns based on field names or column numbers.
