Re: [Zope-dev] Memory problems with ParsedXML ?
Godefroid Chapelle [EMAIL PROTECTED] writes: Karl Anderson a crit : Another thing to keep in mind is that the ParsedXML *product* is a DOM tree and a management interface around it. The management interface only gives you a convenient UI and a place to store a few bits that the DOM doesn't know about (content type, namespace usage, etc.). It's always more efficient to just use the DOM tree and related utilities (parsing, printing), although it is less convenient - you have to know a little bit more about what you're doing. Do you need each of those 2500 product instances? See the createDOMDocument method to create a DOM document without the management interface. I am trying to use createDOMDocument, calling it from an external method: from Products.ParsedXML import ParsedXML def accessXml(document): return ParsedXML.createDOMDocument(document) When using the document returned in a python script, it seems that Zope security prevents me from accessing any DOM attributes. Am I doing something wrong or am I forced to do everything through external methods ? The DOM objects without the ParsedXML management proxies don't have any Zope security information associated with them, so you have to provide it yourself. This is one of the things that the management proxies provide. I didn't mean to sell the proxies short; I should have mentioned that you have to know about providing the features youself that they provide, including security, so this is an area for Zope experts. I've added this to the README. Furthermore, if you're just calling methods on the Document node, without traversing to its subnodes, you're really not paying much of a price; you're basically just putting more function calls between you and the DOM object until you access a DOM subobject. I don't use the python scripts much, but they have very restricted security, being web-edited and all. So yes, one way to give access is to use external methods. Another way is to use a python product and the security machinery available to you there. The unproxied DOM objects are similar to any non-Zope aware python class instances with regards to security; if you're unfamiliar with it, I'd play around with some non-Zope aware dummy class instances, with nested subinstances and attributes, until you know how to make those objects and attributes publishable. -- Karl Anderson [EMAIL PROTECTED] ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] ZPatterns, DataSkins, forms and error checking/handling
On Tuesday 27 March 2001 17:40, Itai Tavor wrote: Hi, I'm trying to work out the best way to check for and report errors when DataSkin objects are created/edited, but I'm having a lot of problems. For form validation, Zope's build-in constraints are pretty useless... things like ValueHandler are a little better, but IMO not good enough. When a user types incorrect data in a form, I don't want to display a page with a list of errors and say "click Back to fix your errors". I want to return the form, with a list of errors and the bad fields highlighted. So I need to perform field checks in the form action method and in case of errors call the original form, giving it an error list. I know that to ensure that object data is always valid I should validate the object in a SkinScript, using WHEN OBJECT ADDED,CHANGED call self.validate(), and raise an exception in validate in case of a problem. But this can't deal with returning the original form. It can only display error pages, and to display nicely formatted error pages it has to return a DTML Method so I can use dtml-raise, rather than directly do raise in validate. So I'm looking at a validate method for use at commit time, a show_errors DTML Method, and a validate_form to call from the form action method... The validate_form method is defined in the DataSkin class. But it is also used when a new object is created from a form, so it needs to be called from a Specialist before the object is created, so I need to import it in the Specialist. But this method might use other methods of the DataSkin class, so I need to import those too... So, to sum up, I need a method used in commit time, that renders a DTML method to raise an error message, another method to verify form submissions and return the form with error messages, and I need to import that method and all other methods it uses into the Specialist. This seems too much work... Can anyone suggest a simpler approach (one that still retains the ability to return the original form in case of errors)? check out dtml-contract. sample form processor with dtml contract dtml-contract this page retrieves records from the db based on user input dtml-params foo:int,optional bar:date foobar:range(int, 0,10) dtml-exceptions bad_user_input /dtml-contract user gets redirected if bar is not a valid date string, and foobar is not a integer compatible string between 0 and 10. if foo is present it must be a integer compatible string (compatible means coercible via int(foo)). if any of these things does not happen than all the collected errors for the page are sent to the error handler bad_user_input. this is not a redirect, the error handler is evaluated in the context of the page with an additonal value added to the namespace to denote the list of errors. page processing stops after evaluation of the tag if an error occurs. this may be clear as mud, i don't know, i tried to make the included documentation pretty inclusive and readable, its not completely insync with the code but it does elaborate on the feature set pretty well. if you have specific questions feel free to ask. so in your case you can just use the original form as the error handler and add logic to it to insert the values if they already exist in the request, and display error messages to the user on the particular vars that have problems based on the existence of the special error variable. hth kapil TIA, Itai ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
