Re: [Zope] Python script URL

Do you mean (in other words) that you want to call the python script directly via the URL? I've wanted to do that myself and tried a few times. All attempts failed. First, just calling the URL would lend Zope to think that you wanted to call the script's index_html method. You really need to have something like a DTML Method call the script using the standard DTML call statement. Alternatively, you can use appropriate form tags (e.g., <FORM ACTION="my_cool_script" METHOD="post> <INPUT TYPE="submit" VALUE="Do it!"> </FORM>) I think the problem is that the request that you make via Zope simply to call an object via the URL doesn't provide the necessariy functionality to invoke a script. In short, the URL request is a "GET" rather than a "POST" operation. Zope experts may have a better explanation. Hope that helps.

Evan Simpson pointed in an answer for Keith Alperin to a Wiki "ZopeForDevelopers". I looked it up and I have a question. Is there something special if the class is a subclass of exception? Regards, Egon

Re: [Zope] Help on mass import of images

Hello Seb, > yes, the data has to be in a string format, but you are passing in the > string "TheImage", AFAICT. No, no. I used the string "TheImage" only as a placeholder for the posting, because a base64 encoded image is _very_ long. Of course I used the correct string representation of the image in my method. You can see it in the file "import_pictures_base64_asstring.py" I sent you to your private mail adress. The code looks like this: >>>>>>>>>>>>> from OFS.Image import Image def import_pictures(self): id='testbild' handle=Image(id,'','',content_type='image/gif') self._setObject(id,handle) self._getOb(id).update_data('R0lGODlhDwK6...<verylongbase64stringofmyimage>...VdzuWAAAA7',content_type='image/gif') <<<<<<<<<<< But this didn't work. The image object was created, but the image data was broken. When I tried to send the binary data of the image as string I got something like this: self._getOb(id).update_data('GIF89a^0^0.....<verylongbinarystringofmyimage>....^Ä^@^@',content_type='image/gif') This resulted in a "syntax error" from the interpreter... :-( I thought about using FTP too. But actually I want to use my own image class. And I don't know how to tell Zope to use my image class rather than the built in image class when accepting images through FTP. > hookable put: (I searched for 'hookable put' on the zope.org search - > follow the resources link at the top of the page for more ideas about > where to search the mailing lists from) > http://www.zope.org//Members/michel/Projects/Interfaces/NewObjectPutHandler I will look at this page...

Re: [Zope] Accessing properties of the folder of a document
by complaw＠hal-pc.org 06 Dec '01

Hi Andreas: Assuming that the DTML Method (for example) is called from within the folder in question, here is some code... The following code reviews each of the Folder and DTML Document objects within the 'context' folder (i.e., the one where the particular method is called). for obj in context.objectValues(['Folder', 'DTML Document']): obj.title # this is the object's title property... # ... Add some code here to do something with the property... How to take properties from a folder and get at its contents? Do this... Put the Python script in the folder that contains the folders you want to review. Then put a DTML Method that calls the python script. Here is the code to put in the python script... for fold in context.objectValues('Folder'): the_folder_title = fold.title for docs in fold.objectValues('DTML Document'): the_document_title = docs.title Chapters 4 and 5 of the Zope Book can help you. You can read the Zope Book online at http://zdp.zope.org/projects/zbook There is also ZopeLabs (http://www.zopelabs.com) that has some very handy recipies for doing common tasks in Zope. Hope that helps.

delete multiple records sql python etc
by Todd Graham 06 Dec '01

06 Dec '01

I've looked through the archives and seen similar posts but none of the replies seem to solve my problem. Here goes... I've got a table called user_accounts that has user_id, application, username that make up the primary key, this is a child table to the user_info table which has user_id as the primary key. As part of the application I want my users to be able to delete multiple rows from the user_accounts table that are displayed in a form via a zsql method that looks like : select * from user_accounts where user_id = <dtml-sqlvar user_id> Based on the result sets of the sql method I build a form that lists the username, user_id, application etc, with one checkbox for each record. My question is how do I pass the all the values from one or more rows to a python script based on whether or not the box is checked. I've tried several combinations of using record(s) converters and list converters but at this point I'm stumped. Thanks in advance, Todd

May be you can add extra hidden <inputs>, which can be also part of a list near the checkbox input. Something like: <form action=throw_away_script method=post> <dtml-in expr="SQL_from_useraccount(user_id=REQUEST['user_id'])"> <input type=hidden name=extra_info1:list value="<dtml-var whateveritmaybe>" <input type=hidden name=extra_info2:list value="<dtml-var whateveritmaybe2>" <input type="checkbox" name="throw_away_list:list" value="<dtml-var user_id>"> </dtml-in> </form> In the python script you can handle the lists (but the lists are not parameters of the pythonscript).

Help on mass import of images
by Sven Rudolph 06 Dec '01

06 Dec '01

Hello, I have a problem to import images automatically. All in all I have 2000 images to import into zope, and I tried the following method: I created an external method "import_images.py": >>>>>>>>>>>> from OFS.Image import Image def import_pictures(self): id='picture1' handle=Image(id,'','',content_type='image/gif') self._setObject(id,handle) self._getOb(id).updata_data('''TheImage''',content_type='image/gif') id='picture2' handle=Image(id,'','',content_type='image/gif') self._setObject(id,handle) self._getOb(id).updata_data('''TheImage''',content_type='image/gif') .....and so on <<<<<<<<<<<<<<<<<< I copied it to <zope-path>/Extensions, created an "External Method"-object in my image folder and then clicked on the "Test"-tab of my external method. I got two different types of errors, depending on the encoding of my image-data. If the string "TheImage", which contains the image data, was base64 encoded, an image object was created, but the image data was broken (view tab of the image object). If the string "TheImage" contained the pure binary data of the image (starting with GIF89a...), I got a syntax error from the parser when I tried to create the external method, as I expected. I also tried to upload the image data with self._getOb(id).manage_upload('''TheImage''') but with the same results. Can anybody help me? P.S. By the way: the script "import_images.py" is automatically created by a perl script.
