Re: [Zope] Why can't I subclass a ZSQLMethod?
What do you mean, you cannot get a view to it? I can change in the management area. I believe ZSQL methods are not supposed to provide the user interface; you use them the way you would use an external method. That means you have to create the form that sends the query parameters to the SQL method, and you have to write the DTML code that obtains the result set, and displays it accordingly. At least that's way I do it; there might be a better way, I don't know. Best, Ivan "Cary O'Brien" <[EMAIL PROTECTED]> writes: > I tried that.

Re: [Zope] Why can't I subclass a ZSQLMethod?
I tried that. You can't add a ZSQLMethod unless there is a connection for it to connect to. There isn't a connection in the products area. Actually If I put a dummy gadfly connection in the Product folder, I can indeed add a zsql method to my ZClass. However I can't get a view to it. I can configure it as a view, but it doesn't show up in the management tabs. I guess it may be possible to leave it invisible and use other methods to set the query, arguments, and database connection.

Re: [Zope] Why can't I subclass a ZSQLMethod?
Why don't you create a ZClass and make the ZSQLMethod to be one of its methods? Then the ZClass can provide the user interface to the SQL query and the result set.

Re: [Zope] Why can't I subclass a ZSQLMethod?
ZSQLMethod is not registered as a base class. I dont know why, but you could try changing it in the init.py... But Im sure there is a good reason why it isnt. - Original Message - From: "Cary O'Brien" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, June 30, 2000 12:59 PM Subject: [Zope] Why can't I subclass a ZSQLMethod? > > I want to wrap a presentation layer around ZSQLQueries, so that > they will have methods to generate an input form [1] for the query, > and generate tabular results if so desired. > > I tried to create a ZClass to do this, but I can't subclass from a > ZSQLMethod. > > Any other ideas on how to do this (besides a class where you have > to tell it the ZSQLMethod to use)? > > -- cary > > [1] Using sql.arguments_str to find out the arguments.
