problems with calling python scripts

ruby042 — 2008-12-01T10:25:26

Hi, I hope you can help me! I have some problems with the combination of Archetype forms and python scripts. I've copied the base_edit files to my new Archetypes-based product and modified base_edit.cpy.metadata: [actions] action.success=traverse_to:string:myScript Now it calls the script when the user clicks on the save button. But it doesn't redirect the user to the "view" tab as it used to do without the script. I also tried it with the portal_form_controller tool: a) Template/Script: base_edit, Status: success, Context type: newCT, Action type: traverse_to, Action argument: string:myScript b) Template/Script: myScript, Status: success, Context type: newCT, Action type: traverse_to_action, Action argument: string:view. I've tried this in various combinations - Either it redirects to the view tab and doesn't call the script, or it calls the script but doesn't redirect to the view tab. So where exactly am I wrong? A second thing which doesn't work is calling a python script when the user initializes the new document. You know what I mean? The user adds a new document. At this moment the url of this object is http://localhost:8080/FooFolder/portal_factory/Foo/foo.2008-11-29.7479322372/edit. The user saves it. Now the url is http://localhost:8080/Foo/name_of_foo. I just can't find out which template I have to modify in order to add a script while the object is still temporary. Thanks!

Allowing only certain fields to be edited

Neil Stokes — 2008-12-01T00:21:36

I am having a problem trying to selectively enable certain fields for edit. I have a certain class of users who are permitted to edit a single caption field in my object type. I have defined a permission named 'Edit Captions' and assigned it to that class of users in the rolemap.xml file within my product. I have specified the write_permission property in the field to be edited (it is a TextField) and set it to the 'Edit Captions' permission. When the user displays the default view of the object, he/she can double-click on the field and the TextAreaWidget renders correctly in write mode. Other classes of user cannot do this, so the write_permission property is apparently being set correctly. The user can enter text in the widget but when he/she clicks the Save button, nothing happens. The Cancel button works correctly but the user can click the Save button forever with no results. I suspect that I need to set some other permissions for this class of user in order for the Save button to work, but I cannot figure out what permissions. I have tried setting the Add permission for the content type, which I do not really want to do since I want the user to be able to edit the caption field for existing content but not create new content. The Add permission made no difference however. I also tried setting the Modify portal content permission, again with no luck. Any suggestions would be greatly appreciated. Thanks in advance, Neil Stokes

LinguaPlone Translation during content creation with FTP/WEBDAV Upload

Sascha Gottfried — 2008-11-24T11:24:17

Hi everybody, the code I am working on is subclassing ATImage to enable parsing of embedded XMP metadata during the content creation TTW or with FTP/WEBDAV. XMP metadata contains image description in a couple of languages. I extended the schema with some fields to make the metadata editable and searchable in Plone. Images are shown in a javascript gallerie where the description and copyright information are shwon below the images in a javascript "lightbox" modal_window (using jQuery/Thickbox). I use "at_post_create_script()" and "manage_afterPUT()" to parse the metadata after Plone stored the image in the ImageField. For internationalization I enabled LinguaPlone in my content type, but now there is the question "When and in which function I should add the translatations of the canonical version of the image object itself. While uploading a bulk of images, I get some "ConflictErrors" and some images get skipped. I do not know a lot about zope transactions that may be important in this case (I read about this for renaming file during creation). But my question aims more to architectural help for my solution. Is it common to translate while content creation??? Is LinguaPlone the right choice for my purposes? My intention: I want to make multi-language metadata in images editable and searchable in Plone. I had a look at ATPhoto, but there is only a view template showing all metadata but not editable. Any advice for making this possible is appreciated. Thanks excerpt of manage_afterPUT() #code other_caption = xmp_data.get('CaptionNL','') other_language = xmp_data.get('OtherCaptionLang','') if other_caption and other_language: self.addTranslation(other_language) # translate translation = self.getTranslation(other_language) # get object translation.setDescription(other_caption) # call method of translated object #code

Re: Archetypes don't have editable DC metadata

Derek Broughton — 2008-11-20T15:18:25

Thanks. That's not quite what I really wanted, but it put me on the right track. Description is in the BaseContent schema. If I subclass ATFolder or ATDocument, I get the Description where I want it - and ATContentTypes just uses: ATContentTypeSchema['description'].schemata = 'default'

Re: Archetypes don't have editable DC metadata

Khairil Yusof — 2008-11-20T01:43:42

Did you add the tagged value schemata = default in your model? It's documented here: "field recycling - copy from parents schema or another source schema and modify" http://plone.org/documentation/manual/archgenxml2/basics/attributes-fields For view, I just add this in my custom template.

Archetypes don't have editable DC metadata

Derek Broughton — 2008-11-19T15:08:24

I have a really straightforward content type that I created for a training session. I created it with ArchGenXML, but that hardly seems important. It inherits from BaseContent, and afaict it should have the Dublin Core metadata - but I don't see a "Description" on the view or edit pages (though the Description() accessor appears to be present when I use Clouseau). Am I doing something wrong? Am I expecting something wrong? from AccessControl import ClassSecurityInfo from Products.Archetypes.atapi import * from zope.interface import implements import interfaces from Products.CMFDynamicViewFTI.browserdefault import BrowserDefaultMixin from Products.myProduct.config import * ##code-section module-header #fill in your manual code here ##/code-section module-header schema = Schema(( StringField( name='stringField', widget=StringField._properties['widget']( label='Stringfield', label_msgid='myProduct_label_stringField', i18n_domain='myProduct', ), ), ), ) ##code-section after-local-schema #fill in your manual code here ##/code-section after-local-schema MyContent_schema = BaseSchema.copy() + \ schema.copy() ##code-section after-schema #fill in your manual code here ##/code-section after-schema class MyContent(BaseContent, BrowserDefaultMixin): """ """ security = ClassSecurityInfo() implements(interfaces.IMyContent) meta_type = 'MyContent' _at_rename_after_creation = True schema = MyContent_schema ##code-section class-header #fill in your manual code here ##/code-section class-header # Methods registerType(MyContent, PROJECTNAME) # end of class MyContent

Thanks for the pointer, I also got how AT gets values from it's default views from looking at code examples. Thinking about it more, it looks like creating custom list views based on the existing code would probably be best. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Re: Collections and Vocabulary Values

Tessa Alexander — 2008-11-16T16:46:50

Dear Khairil Yusof, I've not implemented this myself but I did look briefly at what would be required, to be able to show more user friendly values in the Collection criteria screen, for a previous project. Implementing and using a custom criteria type based on ATSelectionCriterion. Potentially just overriding the getCurrentValues and getCriteriaItems methods. See source code for more info: For the definition of ATSelectionCriterion: ATContentTypes/criteria/selection.py For example of overriding ATSelectionCriterion: ATContentTypes/criteria/portal_type.py Good luck with this, Tessa Khairil Yusof wrote:

Collections and Vocabulary Values

Khairil Yusof — 2008-11-12T05:44:17

Using ATVocabularyManager for my vocabulary fields. By indexing fields in catalog and adding metadata to portal_atct the fields are showing correctly as options in Collection types. The problem is that they're displaying the Keys and not Values of my vocabularies. What's the best way to make Collections automatically return a more friendly and useful value, instead of keys? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Re: UML modeling: extending many classes obscures model

Thomas N. — 2008-11-07T10:31:21

Hi Kees, don't remove it from the model, just from the diagram (both options are offered when you right-click the arrow). You can do the same by selecting the arrow and hitting the DEL key. The underlying model element stays in the model, only it's representation on the diagram is deleted. Thomas kc600 wrote:

Re: SelectionWidget

Neil Stokes — 2008-10-25T11:47:00

The SelectionWidget automatically chooses either a dropdown or radio buttons, depending on how many items you have in the vocabulary. To force it to use a dropdown, specify format='select' for the widget. Cheers, Neil monks wrote:

hello all im using 'SelectionWidget' Archetype to populate field with Drop-down list Following is code: StringField( name='organisation', #accessor='fetchmethod', widget=SelectionWidget( description="Select organisation", label="Select Organisation", label_msgid='masterentryform_activity_label_organisation', description_msgid='masterentryform_activity_help_Program', i18n_domain='masterentryform_activity', ), vocabulary=["aa","bb"] ), But instead of showing drop-down, its showing options in radio-button format. I think im using right widget, 'SelectionWidget', for displaying drop down !! I know when there r few options, it gets displayed in radio button format, but there should be some way or other to display drop-down thanks

Subclassing ImageWidget

Neil Stokes — 2008-10-13T23:17:26

Hi folks, First of all, I'm new to Plone so please forgive me if I don't express this too well. I need to do the following: Display an image on a page along with the supporting information (I have subclassed ATImage to add additional fields/widgets and this works fine). When the user clicks on the 'Current Image - ...' link below the image, I want to display the image at a different size, depending upon the user's defined role. Privileged users will see a full size image while others will see a scaled down image. I have the sizes defined in the ImageField. One way to do this would be to create a method in my subclassed ATImage class that returns a different-sized image using a test based on user.hasRole() - image_large, image_mini etc. However, I notice that the image.pt file (in Archetypes/skins/archetypes/widgets) includes a link to the image file's absolute URL so I need to modify this. A brute force approach would be simply to modify image.pt to call my method but that's a bad idea since it will affect all images. I can subclass ImageWidget, which is a more elegant approach, and simply specify the new widget for my existing ImageField. However, I can't see where to define the link between the widget and the page template. Any pointers would be greatly appreciated. On the other hand, I may be approaching this from completely the wrong direction, so suggestions on alternative approaches would also be welcome. Many thanks in advance, Neil Stokes

Copy - Paste with PostgreSQLStorage doesn't work

Hello, I've defined a new object class with storage into a relational database of some fields. All works fine, except if I try to copy and paste an instance of this class. I get the following error message: Paste could not find clipboard content. In addition: Cut and Paste works fine.
