定制Dexterity的添加和编辑表单

admin

Dexterity relies on ++add++yourcontent.type.name traverser hook defined in Products/CMFCore/namespace.py.
It will look up a multi-adapter with this expression:
if ti is not None:
    add_view = queryMultiAdapter((self.context, self.request, ti),
                                 name=ti.factory)
    if add_view is None:
        add_view = queryMultiAdapter((self.context, self.request, ti))


name parameter is portal_types id of your content type.
You can register such an adapter in configure.zcml
<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:browser="http://namespaces.zope.org/browser"
    >

    <adapter
        for="Products.CMFCore.interfaces.IFolderish
             Products.CMFDefault.interfaces.ICMFDefaultSkin
            plone.dexterity.interfaces.IDexterityFTI"
        provides="zope.publisher.interfaces.browser.IBrowserPage"
        factory=".flexicontent.AddView"
        name="your.app.flexiblecontent"
        />

</configure>

Warning

Overriding add_view_expr or add_view_expr_object in Dexterity factory type information to directly link to a view providedto be not possible. You can manually type Add view link in portal_types, but setting it through GenericSetup installercode is not possible.

Then you can inherit from proper plone.dexterity base classes:
from plone.dexterity.browser.add import DefaultAddForm, DefaultAddView

class AddForm(DefaultAddForm):


    def update(self):
        DefaultAddForm.update(self)

    def updateWidgets(self):
        """ """
        # Some custom code here

    def getBlockPlanJSON():
        return getBlockPlanJSON()

class AddView(DefaultAddView):
    form = AddForm
