Convert from HTML to DOC or from PDF to DOC.

Hi, We are trying to generate a document from Zope with a format no HTML. We have used the library "reportlab" (http://www.reportlab.com) to generate it in PDF format (with python). It is very useful, however we want now to generate it in DOC format (for Microsoft Word). I know that Microsoft Word opens a HTML document directly, but when I open a HTML document with Microsoft Word (v. 97), the document aspect is erased. Anybody to know any Zope product what allows to convert from HTML to Microsoft Word, or from PDF to Microsoft Word, or well, any similar way ? Thanks.

Parse.
by Juan Javier Carrera Obrero 13 Sep '00

13 Sep '00

Hi ! We are using Zope 2.1.6 for Windows NT Server, and Oracle 8i as RDBMS. When the ZSQL methods are runned, the values of the parameters of the SQL query are remplaced by Zope before sending the query to the Oracle database jet (it does not the "parse"). Thus, if two users runs the same query but with different parameters, it is considered as two different queries because the values of the parameters of the ZSQL method are remplaced firstly. When it is realized by more users with diferent parameters, the Oracle's cache is fulling quickly and it is overing. Do exists any way for sending the query of the ZSQL method and theirs parameters, trying that the values of the parameters was remplaced in the database jet, and no previously. Perhaps, it was a ODBC problem, or the Zope code does not allow it. I do not know it. Any body can help me ? Thanks. JUAN JAVIER CARRERA OBRERO e-mail: jcarrera(a)uco.es

Re: [Zope-dev] Custom dtml tag
by Brett Carter 13 Sep '00

Andy: here's what I've gleaned - in a dtml tag's render() method, you get passed in self and a template dict, in my example let's call it 'md'. md is essentially a stack/dictionaryish object of the *current* namespace - and one of the handy things that's always around in the namespace is the 'this' function, which returns the object on the top of the stack. Just lookup 'this', run it, and there you have a reference to the calling object! Ex: def render(self, md) this = md.getitem('this') callingObj = this() return "Calling object was %s" % (callingObj.id()) Note I haven't tested this code.

Custom dtml tag
by Andy McKay 12 Sep '00

12 Sep '00

Im playing with a custom dtml-tag along the lines of <dtm-query foo> constructs a url to a catalog query. It works fine, I would just like to extend it a bit and for this I would need to get to the calling object. For example, there will be a different query depending upon the object the dtml-query tag is contained in. Does this make sense, does anyone know the answer? Thanks in advance. -- Andy McKay, Developer. ActiveState.

Ok, so render gets passed 'md', which is a TemplateDict, which contains a MultiMapping, which looks like a stack of dictionaries, which I am guessing is some sort of namespace stack. So looking at the DT_with.py, it looks like, to create an object in the current namespace, I have to wrap it in an InstanceDict, and push it onto the 'md' using 'md._push'. Does this also cause the new object to be saved in the ZODB? Or do I have to manually add it there too? Also, what does render_blocks do? Why does DT_with.py's render() return it? Do I have to run render_blocks() to insert my new object into the namespace? TIA -Brett

Bug in OFS/Traversable.py
by David Alexander Ranvig 12 Sep '00

12 Sep '00

The unrestrictedTraverse method creates a fake REQUEST "object" (really a dictionary) and sends this to a __bobo_traverse__. If this __bobo_traverse__ uses the object properties of the REQUEST object, or needs the real REQUEST object it will fail. If __bobo_traverse__ raises an exception while being called from the unrestrictedTraverse method, which may easily happen if the author of the __bobo_traverse__ method expected a real REQUEST object, unrestrictedTraverse just raises the Unauthorized exception. This is extremely confusing. I would much appreciate that the _real_ REQUEST object was sent to my __bobo_traverse__, and that the exception propagated is a little more informative. I have worked around this problem like this, def __bobo_traverse__(self, REQUEST, name): if type(REQUEST) == type({}): # do something else: # do what I really wanted to do but would appreciate if the problem did not exist :-) -- Regards David.

I expect, it is the folder containing the external method, too. Therefore, you get this folder as "self". You can provide the "self" explicitly in your call: <dtml-call "breadcumbs(this(),<further parameters>)"> Dieter
