    <p>I am trying to dynamically update a form field based on a variable that is included in a HTTP get variable. Specifically www.site.com/form?id=name. I want to pull the 'id' field from the url and automatically populate the memberID field of the form.</p> <p>I have access to the get variable using self.request.get('id'). However I haven't been able to figure out how to update the form field. I examined the widget documentation <a href="http://packages.python.org/z3c.form/widget.html" rel="nofollow">http://packages.python.org/z3c.form/widget.html</a> but none of the suggestions have worked.</p> <pre><code>class IUpdateEmailFormSchema(interface.Interface): # -*- extra stuff goes here -*- """ """ memberID = schema.TextLine(title=(u'Member id')) email = schema.TextLine(title=(u'Email'), description=(u'The email')) class updateEmailForm(form.Form): fields = field.Fields(IUpdateEmailFormSchema) label = _(u'Change Email') ignoreContext = True @button.buttonAndHandler(u'Update') def handleUpdate(self,action): data, errors = self.extractData() if data.has_key('email'): portal_membership = getToolByName(self.context, 'portal_membership') member = portal_membership.getMemberById(data['memberID']) def updateWidgets(self): print "This is update widget \n\n" import pdb; pdb.set_trace() print self.request.form['id'] #Does not work as specified in http://packages.python.org/z3c.form/widget.html #self.widgets["memberID"].value = self.request.get('id').encode('utf-8') form.Form.updateWidgets(self) updateEmailFormView = wrap_form(updateEmailForm) </code></pre> <p>*Update: updateWidget wasn't correctly indented.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
