Re: [Zope3-Users] Database conflicts errors ?
Le vendredi 08 décembre 2006 à 15:08 +0100, Thierry Florac a écrit : Hi, I'm currently writing an image management adapter for Zope3. It's goal is just to create and store thumbnails on the fly when an image is requested with an additional specific traversal name (for example, myimage/thumbnail will create a thumbnail of a given predefined size, while myimage/200x200 will create a copy of the original image reduced to 200 pixels). These thumbnails are stored in the original image annotations. Everything seems to work fine, except for a little thing : I've created a specific widget so that, when an image is uploaded, a thumbnail of the new uploaded image is immediately displayed next to the data field upload button. But when the form is displayed, a DatabaseConflictError is visible into Zope's log, even if everything seems to work correctly from a browser's point of view. I'm not completely sure to understand what DatabaseConflictErrors are, so any explanation about this kind of problem would be greet. I'll just add for your information that I'm using ZEO... Oops !! Sorry, I found the source of my problem : it was a misconfiguration of the adapter, who was writing data in it's context each time it was called, even if the context was already adapted. A small missing tab and conflicts are gone...

[Zope3-Users] Clipboard
I created a custom content container. However, when I copy(or cut) something to the clipboard, the Paste button does not show up. What am I missing? The content objects seem to be functional in all regards and are stored in a MySQL database, and are inherited from only the Contained class (so they can be contained of course).

[Zope3-Users] which widget to subclass for custom widget?
Sorry I have to bother you once more regarding formlib co :-) (really sorry) In my application I need something very user defined In the Edit Form Edit Purchase Requisition I would like to have a section Supplier Selection, that should operate as a widget. Basically I will use a schema Choice Field as a base, I will just create another view for the choice than the default select field. The whole thing should be seen as generic that returns a value at the end that should be validated and saved: the supplier id (which is the idea of widgets in general what I understood until now) Here the details, should include the following: - question new supplier? radiobuttons yes / no (onchange event to disable / enable textfields that are part of the same widget) - 2 textfields name+address that allow to enter the new supplier info (disabled when above selection no) - link to an independent supplier selection page (with search and list view) - the selection made in the supplier selection page should be updated in the widget as well (overwrite setupWidgets method I think) when applying the form, check in the custom _validate method of my widget, if radiobutton yes / no. when yes then add new supplier else just check if value is already in table. So far the theory, now the first question is, which widget to subclass? SelectWidget, ItemWidgetBase contain vocabulary and probably too high level. SimpleInputWidget seems the better choice?
