textarea/newline-mess
by Page Page 27 Jun '02

Gang, I have a textarea-form here that looks like this: <form action="manage_addTEXT" blabla... <textarea blabla> </textarea blabla> </form> The function manage_addTEXT(self, TEXT="") gets the text from textarea as string in TEXT. It splits the text by using string.split(TEXT, '\n') into lines and stores each line in a database. For editing the TEXT I use a .dtml-script that re-assembles the text line by line: <textarea><dtml-in sqlFetchTEXT><dtml-var LINE></textarea> Please note, that I write it all without any spacing between the tags. One could think that this results in having the lines being displayed in the textarea like this: Line00Line01Line02Line03 but thats not the case. For some reason we see Line00 Line01 Line02 Line03 How's that possible? string.split() removed all the newlines. If I check the database via select LINES from TEXTBASE I see that each line is, in fact, stored separately. If I call manage_addTEXT() directly, however, i.e. not from a form, and pass a bunch of lines to it: manage_addTEXT(TEXT="ichi\nni\san\nshi\n") I end up with all lines concatenated into a single line in my edit-form that so nicely displays the put in via a form. Why is this so? There must be something about how \ns are conveyed via HTTP and how Zope handles it what I don't know. Theories, anyone?

RE: [Zope] Global Variable Definition

Thank you Casey, this information has eluded me through my readings. Thanks again, this is a big help in understanding how Zope works. -----Original Message----- From: Casey Duncan [mailto:casey@zope.com] Sent: Thursday, June 27, 2002 2:59 PM To: McDonnell, Larry Cc: 'Zope@Zope. Org' (E-mail) Subject: Re: [Zope] Global Variable Definition There are three main types of "Global" variables in Zope: - REQUEST variables - Session Variables - Persistent Variables (aka Properties) Request variables are globals that live only for the life of the request. You set them using REQUEST.set('foo', value) and get them using REQUEST['foo']. Session variables live for the life of a user's web session. They are accessible only by that user. To set these you use REQUEST.SESSION.set('foo', value) and to get them use REQUEST.SESSION['foo']. Properties live indefinitely and are saved in the ZODB as metadata of specific objects (such as folders or documents). To make it "Global" to all of Zope, you would set them on the Root Folder. Properties are accessible to all users of Zope. To set/get these you use: object.setProperty('foo', value, type) and object.getProperty('foo'). Note that setting properties is more expensive then session variables, and session variables are more expensive to set then request variables. hth, -Casey On Thu, 2002-06-27 at 14:28, McDonnell, Larry wrote: > > Hi, > > What are the Zope rules in which a variables are classifed as a global > variables?

Global Variable Definition
by McDonnell, Larry 27 Jun '02

27 Jun '02

Hi, What are the Zope rules in which a variables are classifed as a global variables? Can I define a varaible to be placed in the global stack? If so how? Or is there a better way track variables through the site. Also is there a command that will list the namespace? Thanks. Larry McDonnell Proton Energy Systems 50 Inwood Rd.
