Interesting namespace observation
by Roché Compaan 27 May '02

27 May '02

I have a method in the root of my application called "getProxies" that queries a catalog for a given metatype. I have a folder in the root called "Platforms" with a method called "selectInstance" that renders a series of checkbox tags. I call "selectInstance" method from an adjacent folder with <dtml-with Platforms> <dtml-var selectInstance> </dtml-with> This is how this method look at first: <dtml-let control_set="setControl(_, 'PlatformID')" control_name="control_set[0]" control_value="control_set[1]" control_type="'checkbox'" num_columns="3"> <dtml-in getProxies('Platform') sort="Name" prefix="platform"> <dtml-let item="platform_item.id" display_item="platform_item.Name"> <dtml-var inputTag> </dtml-let> </dtml-in> </dtml-let> Doing the above gives a key error for "getProxies", however if I move "getProxies" into the let tag it does _not_: <dtml-let control_set="setControl(_, 'PlatformID')" control_name="control_set[0]" control_value="control_set[1]" control_type="'checkbox'" num_columns="3" proxies="getProxies('Platform')"> <dtml-in proxies sort="Name"> <dtml-let item="id" display_item="Name"> <dtml-var inputTag> </dtml-let> </dtml-in> </dtml-let> It seems like <dtml-let> is doing something with the namespace that makes it impossible for the subsequent <dtml-in> tag to find the "getProxies" method in the root. Any ideas why? -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za

ZCatalog of Folder vs dtml method or ZPT
by hpinson＠indepthl.com 27 May '02

27 May '02

I am experiencing this problem with my ZCatalog... The website is made up of folders, dtml methods, and page templates, using a standard_html_header and standard_html_footer and index_html document. In a ZSearch Interfaced report: Link to a ZCatalogged folder-- the page and inhereted content is returned (like the standard_html_header and standard_html_footer). This is desirable behaviour. Link to a ZCatalogged dtml method or page template-- the page only is returned with no inherited content (i.e. no standard_html_header and standard_html_footer). This is not desirable behaviour. How can I have both-- the page, and the inherited header and footer content appear when the link is clicked in the ZSearch Interface report?

ZSQLMethods inside products
by Thierry Florac 27 May '02

27 May '02

Hi... I'm looking for documentations, samples or tutorials about using temporary SQL objects into Python based products, because I'm new to Zope and can't get it to work. I've tried the following code : from Products.ZSQLMethods.SQL import SQL _v_sql = SQL (id='temp_sql', title='SQL Query', connection_id=self.connection, arguments='', template='select count(*) from MYTABLE') return str(_v_sql()) but I can't get it to work because of an error message : "The database connection <connection> cannot be found.", with <connection> being replaced by the name of an existing database connection present into the acquisition path of the new instance of my product... Any help would be really appreciated... Thierry P.S. : please be kind to answer to this mail directly, because I had to unsubscribe from this mailing list... :-((

using form for add and edit help please.
by Mark Lilly 27 May '02

27 May '02

Hi, I am trying to use the same for for adding and editing. If we are editing a record, i want to insert its value. If we are adding, i want to have a blank input text element. Instead of having two input elements for each form element, i have come up with this: <td class="add" valign="top"> <input type="hidden" name="prev_input_name" value="" /> <input type="text" name="input_name" id="input_name" tal:condition="exists:task/task_name | nothing" tal:attributes="value python:test(task, 'insert here', '')" /> </td> Here is the code that fills the task variable: <div tal:define="theTaskId request/task_id | string:0; task python:root.CT.Scripts.P_Scripts.getTask(theTaskId)"> If task_id = 0, the python script will return an empty list. Otherwise, it will return the 0th instance in the Catalog's collection. I can't figure out what to put in place of 'insert here' in the above Input element. I tried to use task/task_item but i get a NameError on global name 'task_item' is not defined. I tried getattr(task, 'task_name') but got an AttributeError on task_name. I can't define a variable using task/task_name, because if it's empty, it returns an error. Any thoughts on how i can pull this off? Thanks, mark
