SQL export in zope

MatthewWilkes (Matthew Wilkes) — Wed, 08 Mar 2006 08:24:28 GMT

Takes the result of a Zope SQL query, and an ordered list of field names, and outputs a CSV file as the resultant web page. Should be called like this:

return context.sql.ordered-sql2csv(context.sql.exportOrders().dictionaries(), ["fullname","email","phone","address","town","postcode","children","adults","comments"])



## Script (Python) "ordered-sql2csv"

##bind container=container

##bind context=context

##bind namespace=

##bind script=script

##bind subpath=traverse_subpath

##parameters=sql, fo

##title=

##

container.REQUEST.RESPONSE.setHeader("Content-Type", "text/csv", 0)

sep = ""

for dk in fo:

  container.REQUEST.RESPONSE.write(sep + dk)

  sep = ","

sep = "\n"



for rec in sql:

  for i in range(0,len(fo)):

    data=rec[fo[i]]

    dl = str(data).split(',')

    data1 = " ".join(dl)

    container.REQUEST.RESPONSE.write(sep + str(data1))

    sep = ","

  sep="\n"

Check that a user has permission on all parents in Zope

georgehotelling (George Hotelling) — Tue, 19 Jul 2005 22:41:19 GMT

If you need to be sure that a user can view an object, you need to check the View permission not only on the object but also all of its parents. To do this, I slightly modified the script at http://zopelabs.com/cookbook/1018022911 so that it uses the context object and specified the View permission.

Create a Python script in your acquisition path (I used portal_skins/custom) named can_view and paste in this code:

permission = "View"

try:

  object=context

  if not object.acquiredRolesAreUsedBy( permission ):

    for p in object.rolesOfPermission( permission ):

      if p['selected']:

        if p['name'] in user.getRoles():

          return 1

  else:

   return 1

except:

    pass

return 0

Then you can check the permission in TAL like this:
