Email files via a form thru Zope
by Michelle 28 Aug '00

28 Aug '00

Hi, I was wondering if anyone can help me. I would like to have people send files through a form so I have created a form: <form name="form1" action="senddocument" enctype="multipart/form- data" method="post"> <font size="2" face="Tahoma"><b>Name:</b></font> <p><input type="text" name="textfield" size="30"></p> <p><font size="2" face="Tahoma"><b>Email Address:</b></font> </p> <p><input type="text" name="textfield2" size="30"></p> <p> <font size="2" face="Tahoma"><b>Please attach your file:</b></font></p> <p><input type="file" name="attached_file" size="30"></p> <input type="submit" name="Submit" value="Submit"></form> with the "senddocument" method doing:  To: Feedback Recipient <michelle(a)non.com> From: Zope Feedback Form Subject: New Document Feedback from :  Name of Sender:  Attached File:   Now (theoretically) you are supposed to be able to attach a file (either a .doc or a .xls file and it magically gets emailed to me. I get an email but the file does not attach. Unfortunatley I am not the most techo-minded person around and I have probably missed the most simplest bit but I just cant make it work!!! This whole Python and external methods and all that sort of stuff has been confusing me like you wouldnt believe! Soooooo I was hoping that there would be some wonderful person out there to show me the light! :) Look forward to hearing from you!

Re: [Zope] How to get PARENTS[-1] from within a Python Product
by Dieter Maurer 27 Aug '00

27 Aug '00

Ira Hochman writes: > How does one retrieve the equivalent of PARENTS[-1] from within a Python > Product in Zope? ZPublisher places "REQUEST" at the top of the acquisition chain. "PARENTS" is an attribute of "REQUEST". Therefore, you should be able to simple use "self.PARENTS[-1]". If it does not, try "self.REQUEST.PARENTS[-1]". Dieter

Re: [Zope] keeping state of tree over different documents
by Dieter Maurer 27 Aug '00

27 Aug '00

Marcus Schopen writes: > The problem that occurs is, that the tree`s open/close state is not correctly maintained over the different documents. A solution to that might be to append the state of the tree after selection of a link to the it's URL as ?tree-s=.... ; that means pass the future state of the tree to the selected page by using URL-Parameters. > > Any ideas how to do that or any other ideas? I think, this is a great idea! It would avoid the cookie to save the state and would therefore be much more robust. I have extended the TreeTag to allow explicite control of the hotspot (i.e. the icon to control opening/closing a branch). The extension is not yet general enough to support passing the future state (after the operation) but still uses the incremental state change. The extension is not easy to understand and packaged with our changes to the TreeTag. There may be another way to influence the hotspot as Zope magically adds a "target" in the left frame of its management screen. I did not yet look at how it works. You find the function to compute the new state in "TreeDisplay.TreeTag.apply_diff". Dieter

ZServer stepping on Content-Type and Content-Length?
by Jeff Hoffman 27 Aug '00

27 Aug '00

Hello, I am playing around with the new ExtFile product released a few days ago, in addition to a similar product I wrote myself. Both are exhibiting an unusual behavior. In the index_html method, I have: RESPONSE.setHeader('Content-Type', 'video/foo') RESPONSE.setHeader('Content-Length', 1212) Then, I return the file data. If I launch python and do: import Zope, ZPublisher ZPublisher.Zope('/path/to/myfile.mpg', d=1) I can trace the execution of these lines. The headers are set correctly in the response and, as far as I can tell, are returned correctly in the last statement my trace executed ("return response"). However, when I telnet to my web port and do: HEAD /path/to/myfile.mpg HTTP/1.0 I get: Content-Type: video/mpeg Content-Length: 0 Remember, I set content-type to video/foo, and length to 1212. These have been stepped on, I believe, by ZServer. I found this section in ZServer/medusa/default_handler.py: request['Last-Modified'] = http_date.build_http_date (mtime) request['Content-Length'] = file_length self.set_content_type (path, request) While I don't know, for sure, that this is what's causing my problem, it looks suspect to me. The curious thing is, using Zope's File object (defined in lib/python/OFS/Image.py), I get the correct Content-Length coming back. I did not check to see if Content-Type was overwritten or not. As far as I can tell, there is no difference in the way my code returns the file data versus the way Zope's File object does. Anyone know what's going on? --Jeff --- Jeff K.

How to get URL of folder (name unknown) with a certain property?
by Tim Hicks 27 Aug '00

27 Aug '00

I am trying to figure out how to get hold of the URL (using absolute_url I presume) of a folder with a property called "sehs_root_folder" set to "yes". I do not know what the name of this folder is, so I am finding it difficult to use the hasattr function, and I don't have any way of knowing where abouts in the document tree the folder is (except that it must be a 'parent' folder of the one that contains the dtml-method that I am running the code from). Does that make any sense? I'm finding it difficult to even express my question, so searching the mailing list archives is proving fruitless. I'd appreciate any pointers tim ps. The reason I'm trying to do this is to make my site more portable. I would like to be able to change servers and/or folder names on my server without damaging all the links and addresses to images/files on the site. As such, everywhere that I have any sort of link/address on the site, I currently use the following: <dtml-var path>/address/to/whatever/ <dtml-var path> is a method that resides in the 'root' folder of the site, and in it, I put the current appropriate path for the site. However, I would like to make this method automatically figure out the appropriate path. Therefore, I gave the 'root folder' a property called "sehs_root_folder" that I hope to search for. If you have a more efficient way of solving my problem, please let me know. Tim: tim.hicks(a)iname.com

Re: [Zope] is <dtml-unless someIndirectVariable> possible ?
by Rik Hoekstra 27 Aug '00

I have a lot of REQUEST like this one to check, depending on what documents are in the folder. <dtml-unless SOMEREQ> <dtml-call "REQUEST.set('SOMEREQ','defaultvalue')"> </dtml-unless> RH: this should work. It works with me so i gave all documents concerned 2 properties myPropName,myPropValue (in our example myPropName : SOMEREQ myPropValue : defaultvalue) So i'm able to iterate the documents and check the properties and set the REQUEST. <dtml-in "objectValues(['DTML Document'])"> <dtml-if "_.hasattr(this(), 'myPropName') == 1"> <dtml-call "REQUEST.set(myPropName,myPropValue)"> </dtml-if> </dtml-in> this works OK. But, I can't find a way to generate the <dtml-unless SOMEREQ> tag. Passing the value of myPropName seems to fail (erreur while parsing the syntax, or check the 'myPropName' instead of his value). I tried a lot of things and syntax around <dtml-unless myPropName>, but it failed. RH: Um, as you describe it, you mix up the name of the property and its value (but that might be a matter of desciption). Try something like the following <dtml-unless "myPropName==SOMEREQ"> <dtml-call "REQUEST.set('myPropName', defaultvalue)"> </dtml-unless> note that 1) this will only work if there is a myPropName and a defaultvalue variable in the namespace and 2) this won't change the value of the property hth Rik
