[Zope3-Users] z3c.form - how to set single default values from another object?
Hi, Hi, I have here an add form which is based on an interface like this: class IMyObj(Interface): value1 = TextLine() value2 = TextLine() In my add form, I need to display a default value for value2. This default value is stored in another object, however, no default value should be given for value1. I'm desperatingly trying to implement this via z3c.form through various ways, but none seems to work. I had a look at widget.py, line 73 (the update method where the value is retrieved) and found the following: 1.1) From Request: I could solve my problem like the following in my update() method: self.request.form['form.widgets.value2'] = 'mydefault' However, I don't think it's a nice solution to modify the request for a default value. 1.2.1) Via a datamanger: Seems to be not possible as I can't explicitly set ignoreContext = False for a single widget. Therefore this fails as I don't have a datamanager for value1. Moreover it seems the datamanger is not a named adapter: value = zope.component.getMultiAdapter( (self.context, self.field), interfaces.IDataManager).get() Therefore in my case, where value1/value2 are both TextLines and have the same widget, it's not possible to register the datamanager for value2 only. 1.2.2) Via the field default value: Maybe possible by cloning the field in the update() method of my form and setting a default value there, however, this looks lie a _very_ bad style to me. 1.3) From an object attribute (don't really understand what this Step is for): Seems also not possible as there's once again no way to register a named adapter here and therefore the absence of value1 as object attribute will lead to an error: adapter = zope.component.queryMultiAdapter( (self.context, self.request, self.form, self.field, self), interfaces.IValue, name='default') So, either I missed somehow a good solution, or my pattern is not addressed in z3c.form. In this case, I'd suggest to handle this case in two ways: 1) Add e.g. Step 1.2.3, which queries after a named adapter where the name is the field name. This way, I'd be able to register an adapter that retrieves the default value from somewhere else. 2) Provide a way to tell single widgets (and not only the widget manager) to ignore/not ignore the context. This way, I could simply use the getContent() method in my view, although there's once again the same problem if the default values don't come from a single object (as my getContent routine cannot decide which object to return). I don't know if these two solutions would conflict with other parts of the framework, maybe there's an even better solution?

Thanks to Philipp von Weitershausen's book, my previous problems were solved. So I downloaded the zope 3 tar.gz and started to practice... only to discover eggs, buildouts, paster and friends (yes, pretty much I've been living under a programmer's rock). Well, no problem. After reading http://pypi.python.org/pypi/zopeproject/ and http://pypi.python.org/pypi/zc.buildout I was on track again. So basically, what I do is: # Create a virtual environment $ python2.4 bin/virtual-python.py --prefix=~/zope3/ # install easy_setup $ ~/zope3/bin/python bin/ez_setup.py # Install zopeproject (of course, all these steps are made just once) $ ~/zope/bin/easy_install zopeproject # make the projects $ ~/zope/bin/zopeproject webdev and then edit setup.py, buildout.cfg. and work in src/webdev. So long, so fine. But here come my doubts: *) Is it the way the experienced zope developers work? How do you set the environment for a site or a package development? Except for the zopeproject thing it is the way we work, edit the buildout.cfg and setup.py for the project needs. We also have a versions.cfg and nail all versions to the known working versions. Only update versions if really needed. *) I'm working in more than a package. I'm developing a blog, a user manager, etc. Should I create a new project for each package? How do I include in my site (under development) my packages (under development)? First of all each package should have it's full test environment to be able to developt the package independent of an application. If you want to use the current develop version in you application just set the develop path to your local working copy of the package. *) What recipe do you use to fetch a package via svn? We have no need to fetch packages using svn, we only use eggs. As stated above if you need to use a local develop version of a package we temporarily add a develop path for that package.

I am not familiar with z3c.form (being stuck with maintaining a project based on Zope 3.2 means you don't get to play with new toys). With zope.formlib you could solve this by passing an initial data dict to the setUpWidgets call. Doesn't z3c.form have something like that? You mentioned that you looked at the source where the widgets were updated. I suggest you look at the place where the widgets are created initialized.

This is the approach that I envisioned. You basically have to provide this adapter to provide a default value. From z3c.formdemo.message.browser, line 27: DefaultDate = widget.ComputedWidgetAttribute( lambda adapter: datetime.date.today(), field=interfaces.IHelloWorld['when'], view=IAddForm) Then register the adapter as follows: adapter factory=.browser.DefaultDate name=default / You can create any function you like to compute the dynamic default value. The `adapter` argument has access to the context, request, form, etc. Regards, Stephan -- Stephan Richter Web Software Design, Development and Training Google me.

These are good questions. We started already collecting the schema fields in z3c.schema. So I think z3c.formwidget should only contain the widgets and converters. Ah, ok, I was not aware of the z3c.schema package. Anyway, Roger suggested to solve this in another style by creating an egg for each schema and widget, e.g. z3c.schema.email, z3c.formwidget.email, z3c.schema.telephone, z3c.formwidget.telephone etc. He made some good points there, so I'm unsure which way to go? I think this leads to an eggsplosion, but Roger stated that this is exactly what the concept of eggs is all about. However, I'm still unsure that handling hundreds of eggs is really a viable way. For instance, I use z3c.form from the SVN repository, this way I always have the newest release via a simple checkout. However, it was quite some work to checkout/configure all other packages z3c.form needs, such as z3c.pagelet, z3c.formui etc. etc. So, in case of an eggsplosion, where a package has e.g. 50 dependencies, using an SVN version is a mess, especially when a SVN version depends on code available only in the SVN and not as Egg. Are such cases all really thought out?
