The reason I was using the external method was to avoid the user from witnessing any use of the management interface.

Reimporting products without restarting server
by Chui Tey 13 Mar '00

13 Mar '00

Having a slow machine, not having to restart the server when testing is important for me (it is a 20 second start up for me). Is there a script around to let me do this... ? Here is what I have done so far (using bits of snippet from the source): log into the monitor, and do this: import Zope app = Zope.app c=app() OFS.Application.initialize(c) c._p_jar.close() del c The net result is all items in the the "Add New Item" combobox double up, and I am not even sure if this does the trick...

mange_changeProperities external method
by M.J. Stahl 13 Mar '00

13 Mar '00

I have an a form in which the user can edit an instance of a ZClass and resubmit the data. This data is to be used instead of the data that is currently listed within the properties of said object. After submitting the change I get this error: Error Type: AttributeError Error Value: 'string' object has no attribute '_properties' The code that it is referring to is: def editTaskProperty(self,REQUEST,RESPONSE): taskobject = self.taskstorage.REQUEST['task_id'] for p in taskobject._properties: taskobject._setPropValue(p['task_title'], REQUEST['title']) Can anyone give me any insight as to how the proper method of changing the properties listed on an instance without the user catching any wind of the management interface? Best regards, Mark

Setting title in an external method
by Greg Ward 13 Mar '00

13 Mar '00

Hi all -- A common idiom around here is to use an external method to process a form and, if an error that the user can't fix occurs -- eg. you can't view such-and-such an object because it doesn't exist, or you don't have privileges -- use "return" to show them the contents of a DTML method that explains the problem. Here's a simple example: def my_xm (self, REQUEST=None, RESPONSE=None): # ... churn away, processing the form ... return self.my_dtml (self, REQUEST, RESPONSE) Here's the source for the "my_dtml" DTML method: <dtml-var standard_html_header> title: <dtml-var title> document_title: <dtml-var document_title> This is the <dtml-var document_id> Document in the <dtml-var title_and_id> Folder. <dtml-var standard_html_footer> Both "my_xm" and "my_dtml" are in the root directory of an almost-fresh Zope 2.1.4 installation. The problem is that the "title" when I call "my_xm" (ie. the "Title:" HTTP header and "<TITLE>" HTML tag) is just "Zope", which I presume is the title *of the folder* containing the external method. Yuck. I want the form result to have a title of its own, eg. "Error Viewing Blah-blah". What's the best way to do this? Possibilities that occur to me: * redirect to the error-reporting DTML Method instead (but I like to keep the number of redirects to a minimum) * use a DTML Document instead of a Method (not sure if this will work, and sometimes I really do want it to be a method -- eg. it might be called from within a larger Document in some context) * set some magical attribute of 'self' or 'RESPONSE' in the external method; I tried "RESPONSE.setHeader ('Title', 'My Title')", but that didn't work Any other ideas?

manage_delObjects problem
by M.J. Stahl 13 Mar '00

13 Mar '00

Can anyone give me any insight as to why the below URL doesn't work. http://diis/inventory/outofstock/OOSStorage/manage_delObjects?id=8185 After the URL is visited the manage screen comes up and tells me "No Items were specified!" So I am a little confused as to why there is no item specified, when I am sending the 'id' number with the URL, and will the activation of this hyperlink take me to the manage screen or just delete the object and leave the user at the page where the hyperlink was requested from. Best regards, -M.

recommended db?
by Sam Gendler 13 Mar '00

13 Mar '00

I need record level locking in a database, and I need it quickly, without having a huge learning curve or added cost of administration. What do folks out there recommend. Does Postgres allow record level locking? I am on a linux platform, and refuse to use any MS products, so don't go there. Additionally, I need to be able to easily export database content as both SQL statements and in some sort of delimited text file format. I can do the latter with Zope, of course, but it is fairly slow and expensive. MySQL does all of that nicely, but doesn't have record level locking. Please respond to me as well as the list. --sam -- Sam Gendler Chief Technology Officer - Impossible, Inc. 1222 State St. Suite 250 Santa Barbara CA. 93101 w: 805-560-0508 f: 805-560-0608 c: 805-689-1191 e: sgendler(a)impossible.com

getting port number into URL - was where port num gone
by Andy Heath 13 Mar '00

13 Mar '00

I'm sorry to ask this again but there must be a way of getting a port number into a url without being explicit about the address. There has to be because absolute_url() does it inside a tree. I just don't know what I can use and the expression syntax to do so. I have this root ltscimages someimage somefolder somedtlmdoc and I'm running both apache and zope. Some pages get served zope-->apache and some direct from zope. ZServer is running on 8080. Within somedtmldoc I want an image from ltscimages. This code <dtml-var "ltscimages.someimage"> produces a reference to the image but without the port number. In the ouput html I want http://host:8080/ltscimages/someimage but I get http://host/ltscimages/someimage I can work around this by serving the image via the zope-->apache method but that's crummy - I want only to use apache when I have to because of the efficiency effect. Putting the port in explicity is also crummy because its less transportable. How can I either 1. always get the port num in or 2. get the port in if its not the default 80. Elswhere in the same code absolute_url() does this correctly for code inside a tree. Would there be a way to use this here? Sorry for so many newbie q's. I promise I'll give back when I can.
