If so, you use its push method. If the thing, you would like to "with" is an object (rather than a mapping), you would wrap it into a "DocumentTemplate.DT_Util.InstanceDict" before it is being pushed. Dieter

python methods

Oh, another thingy: An object called Python method is supposed to appear on the Add list? or am I supposed to emulate it with some kind of external method and files? If that's the case, well, sad kludge. Please let me know. ---------------------------------------------------------- Universidad Federico Santa Maria - Campus Guayaquil

where is the ID?
by michael angelo ruberto 28 Sep '00

28 Sep '00

hello, i have another problem. the ZClass i have created, which is based upon the DTMLDocument base class, is having a strange problem and i'm clueless about where to look to fix it. when i try to reference the ID through DTML i get this: <a href="http://komputer:8080/Efolder/<string>"> here's the DTML that generated this: <a href="<dtml-var URL1>/<dtml-var id>"> was there something i overlooked while creating the ZClass? i appreciate any responses. -<mike>-

This behavior is targeted directly at DTML's original purpose, which was to generate HTML reports against the objects published by Bobo/Zope; the interoduction of more powerful programming constructs (the let tag, expression syntax) have not always jived well with the more ancient core of DTML.

Brad, I think I can provide some information. I have added a jpg to an interbase table and have successfuly displayed it in ZOPE. First off you may know that Interbase does not store BLOB data directly in a table's blob column. It stores the data elsewhere and then stores a "pointer" to it in the table column. This means that BLOB data MUST be inserted via program code and thus you cannot do the following in a Zope SQL Method: insert into the_table (blob_column) values (blob_data) If you are using the gvibDA you can code an external method to do this: import gvib cn = gvib.connect(...) cr = cn.cursor() cr.execute('insert into the_table (blob_column values (?)', (blob_data,)) cn.commit() cr.close() cn.close() What I did to display the JPG may or may not be legal but here is what I did. Code an external method (saveimage) to save the jpg to a temporary file. My codewas: def saveimage(ifile, idata): fout = open(ifile, 'wb') fout.write(idata) fout.close() Then I coded an SQL Method to select the blob column. My example table has one row in it. select picture from sela Then I coded a DTML Method to do the rest: <dtml-in selasql> <dtml-call "saveimage('/tmp/sela.jpg', picture)"> <img src="file:/tmp/sela.jpg" alt='sela'> </dtml/in When 'viewed' the reulst is a nice picture of the lovely Sela Ward. :-) Good Luck and Regards, Bob Tierney _________________________________________________________________ Robert E.

SQL errors

28 Sep '00

Using ZODBC Database Adapter to connect to an MSSQL and I can call the sql method in dtml eg: <dtml-try> <dtml-call "SQL_add_user(REQUEST)"> <dtml-except sql.error> Error! </dtml-try> But does anyone know a way of trapping the specific error eg: database down, key violation etc...? Or do I have to hack ZODBC to return different errors? -- Andy McKay, Developer. ActiveState.

IEMethod and Owner permissions
by Peter Bengtsson 28 Sep '00

28 Sep '00

Hello I'm using the IEMethod product installed on Zope 2.1.6 In a folder object's security tab, I have set Owner to be allowed to change IEMethod, but an ACL User in that folder (being Owner) can't. When logged in as this Owner user, I can't change (File) my changes in the IEMethod. Any similar security setting for DTML Documents or DTML Methods works with this logic. Ideas? Solutions?

Getting properties of objects
by Daniel Rusch 28 Sep '00

28 Sep '00

I am trying to build a property seach engine that will search an entire Zope site for a names property (i.e. color) and it would return a list of all objects with that property and it's corresponding value. Addtionally, as an option, I would like to display all properties of all objects (i.e. pass in a wild card instead of a name and you get all properties in the site). I started on the wild card requirement first: I have been able to get all the properties of the root level folders, but not the the DTML Documents in the root level. Additionally, I haven't been able to recurse into the sub folders. Any thoughts???? Dan <dtml-if "property=='*'"> <dtml-call "REQUEST.set('num','1')"> <table> <th colspan=1 align=left><b><u>Object</u></b></th><th colspan=1><b><u>Property</u></b></th><th colspan=1><b><u>Value</u></b></th> <dtml-in "objectValues('Folder')"> <tr align=left><td valign=top><b><dtml-var num>: <dtml-var id> </b></td> <dtml-in "_[id].propertyItems()"> <td valign=top> <dtml-var sequence-key></td><td><dtml-var sequence-item></td></tr> <tr><td colspan=1> </td> </dtml-in></tr> <dtml-call "REQUEST.set('num',_.int(num)+1)"> </dtml-in> </table> </dtml-if "property=='*'">
