RE: [Zope] How to get the DTML code from a document/method?
Hi Gilles:
I want to make prints of my document/method DTML code(the edit textarea is to small), how can I get it from inside DTML?
Strange I _just_ answered this for a customer! Here you go: This is implemented as a Python External Method. I've pasted the source code below: Python source --> import string Python source --> Python source --> def view_source(self,path): Python source --> "view the source of a Document" Python source --> id=string.split(path,"/")[-1] Python source --> if not id: id="index_html" Python source --> if not id in self.documentIds(): Python source --> id="index_html" Python source --> doc=getattr(self,id) Python source --> return doc.read_raw() Python source --> return id This gets called from a dtml_source document whose contents (strangely enough!) can be seen at: http://www.zope.org/dtml_source?path=/dtml_source [Man, I think that's cool!!!] Then, on any document you can use something like: http://www.zope.org/dtml_source?path=/ --Rob Page

This gets called from a dtml_source document whose contents (strangely enough!) can be seen at:
I'm doing something daft here - I keep getting <!-- Error type: Error value: read-only buffer, class --> ..... .... <!-- Traceback (innermost last): File lib/python/ZPublisher/Publish.py, line 877, in publish_module File lib/python/ZPublisher/Publish.py, line 590, in publish (Info: /dtml_source) File lib/python/OFS/DTMLDocument.py, line 212, in __call__ (Object: dtml_source) File lib/python/OFS/DTMLDocument.py, line 208, in __call__ (Object: dtml_source) File lib/python/DocumentTemplate/DT_String.py, line 513, in __call__ (Object: dtml_source) File lib/python/DocumentTemplate/DT_Var.py, line 239, in render (Object: view_source(path)) File lib/python/DocumentTemplate/DT_Util.py, line 266, in eval (Object: view_source(path)) File <string>, line 0, in ?

Is there a reason why there are two return statements in the external method, when it seems that only the return doc.read_raw() is going to be called? tone ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2
