Continued with Calendar Panel¶
I managed to have the Calendar panel filled with Lino’s Events. (I added a new report PanelEvents, virtual fields Event.dt_start and Event.dt_end)
But another problem appeared: I want (or rather need) to use the FormPanel defined by Lino when editing the details of an event. That seems not so easy because Lino.FormPanel constructor takes a special parameter ww. All Lino panels have this pointer to their containing window wrapper.
But Ext.ensible.cal.CalendarPanel has no API to specify a custom function that creates the editor form, I must replace the ‘extensible.eventeditform’ with my own class (whose constructor must work with the standard ExtJS signature).
extensible-all.js does:
Ext.reg('extensible.eventeditform', Ext.ensible.cal.EventEditForm);
And I plan to do:
Ext.reg('extensible.eventeditform', Lino.EventEditForm);
But first I want to make Lino.FormPanel usable without a containing_window in the constructor.
This causes an avalanche of changes:
Moved the save() functions from DetailWrapper and InsertWrapper to a single function in FormPanel. It tests rec.phantom to decide whether it’s a POST or a PUT.
Seems to work. Checkin.
Changed the generated javascript code.
Changed analyze_models() in kernel.py, preparing to the new concept for defining Details.
The mechanism for rendering the picture of a person was very sophisticated
and required even an additional AJAX call to get the URL of the picture.
And the result was suboptimal since the picture were stretched to
fill the rectangle.
Replaced by a simple lino.fields.HtmlBox field:
def image(self,request):
url = self.get_image_url()
s = '<img src="%s" width="100%%"/>' % url
s = '<a href="%s" target="_blank">%s</a>' % (url,s)
return s
image2.return_type = fields.HtmlBox()
Layouts are now still Report-based, but everything is ready to make them model-based.
Checkin 20111126 07:03 because it seems to work so far (except that before_row_edit isn’t called on a GridPanel and probably some more bugs).
DetailLayouts are now stored in the model, no longer in the Report.
New classes lino.reports.Detail and lino.reports.DetailHandle.
There is one Detail instance per model, stored in model._lino_detail
which is None for models that have no .dtl files.
There is still no possibility to define different Detail Windows
per Model and there’s no need for it yet, but that’s now possible.
lino.ui.extjs3.ext_ui.ExtUI.build_lino_js() now generates the
definition of a FormPanel subclass for each Detail.
Checkin 20111127 01:27 because it seems to work so far.
Next step was to generate also a class definition of a GridPanel subclass for each Report. Something like…
Ext.namespace('Lino.thirds.ThirdsByOwner')
Lino.thirds.ThirdsByOwner.GridPanel = Ext.Extend(Lino.GridPanel,{

ww.main_item = this.main_grid8980;
ww.show();
}
And then I noticed that we must subclass the Model’s FormPanel, once for detail and once for insert.
First success: the Calendar Panel now shows Lino.cal.Events.detailPanel when we click on “Details…” of an Event.
TODO:
The Lino.cal.Events.detailPanel is not yet filled with data. Must subclass Lino.cal.Events.detailPanel so that it behaves like the Ext.ensible detail form.
bug with master params
Checkin
Some internals documentation:
A slave panel needs to know the master parameters to get its data:
mk (“master key”) is the primary key of the current record, required by all slave report requests,
mt (“master type”, the ContentType of the master) is needed only for Reports on a generic master (XxxByOwner).
Grids and Forms on a slave report need a caller (either a FormPanel or a GridPanel) which will act as their master (providing a method get_master_params() which they call (1) upon render and (2) when on_master_changed)
Another thing are base parameters. The concept is taken over from the ExtJS Store baseParams config parameter.
query (
lino.ui.requests.URL_PARAM_FILTER) : the current value of the search_field in the top toolbar of a grid.mk and mt are stored in the base_params of a slave panel.
A FormPanel takes the base
