Hi, i need to ask for extra info to the user when a button is pressed to fill a confirmation file.

What i have now, is a button which when is pressed creates a xml file, with the data of the current record, and i need to ask the user to fill 2 text fields to add to that file.

What should i use? a wizard? i didn't use them yet and i don't really know how it works.

Yes you need a wizard.

Specifically a wizard defines an interaction between between a client and the server.
Specifically your requirement requires an interaction between the client and the server.

They aren't too hard.

Basically your button will now call the wizard.

Your wizard will contain 2 fields of type char.

Your wizard will have an OK button, and the return of the function on the OK button will generate your xml file. Obviously I don't know the specifics but look at wizards that define reports on records (i.e wizards in the right pane of an object), step through them, you will see model and id's of calling object passed in context.

I see, i created the wizard, and it shows the form, but, can i call a function/method from the parent object when i press Ok on the wizard or should i implement the function in the wizard?

I mean i want to call the method i called in my button at first time, because that method check some values in the object and call another method with a parameter. I use that method in various buttons and the parameter defines which type of structure it should be used to create the xml file.

yes you can call whatever function you like. From memory their is a good example in stock module, wizard folder. It is called stock_onshipping_invoice or something like that. That gets a couple of inputs like date, and journal then calls the invoice create function of stock.picking before returning True.

It is the wizard called when you create invoice from picking.

I have searched, looked at sotck module and tryied to call the main function when i press ok on the wizard, but i don't really know how to, it always launch some exception, maybe i'm calling the function in the wrong part of the code, where should i call the function or how? I tried with something like my_module.my_object.my_function on the wizard action, but it doesn't work

Any hint?

Is basically it. No different to any other module except accessing ids from context. I assumed a standard signature but you get the idea.

Many thanks, now the function launches well when i press Ok button in the wizard, but now, how i can read the fields i entered in the wizard?
Is there an example in any module?

By the way i am getting this error TypeError: read() got an unexpected keyword argument 'load' when i try to read values, i overloaded the read method which is causing that exception, but it works well by itself.

This is the standard way

data = self.read(cr, uid, ids, context=context)[0]

then you just refer to fields like

field_x = data['field_x']

Ok, i tried that but still getting exceptions, to prevent the (TypeError: read() got an unexpected keyword argument 'load') i comented my overloaded read method, then with field_x = data['field_x'] i got ,KeyError: 'field_x'

I don't know what i am doing wrong here is my code:



send_usu function, part of club.activees object which calls the wizard :

So ther i got -> KeyError: reasons

And this is my read overloaded method which causes the first exception TypeError: read() got an unexpected keyword argument 'load'

You need to read your wizard values in the wizard, and then pass to your function so more like



or else pass in context and access there

Ok, i got it, it works well now, btw i solved the problem caused by overloading read method changing all the uses of .read and .browse methods in my code with direct Select's to data base.

Glad you got there in the end.

Personally I hate direct selects, and I can honestly say I have never found a reason to use them over the ORM, excepting some sql views and reports, and I've written a decent amount of code. Additionally I have never found any reason to change the function signature of any ORM method. If you are in a situation where you really need to extend it, then adding to context and testing in your overload is usually the most you need to do and often not even that. Haven't done for read or browse, but certainly for write, unlink, copy, name_get, name_search so I imagine the principal is the same.

I preffer also use ORM methods of course, but i really needed to overload read, create, write and unlink methods and when i overloaded the read method all reads i did in other parts of my code causes the exception, so i decided to use selects.
