amf ReferenceError: Error #1056

[Larry Erickson]

Trying to upgrade rails/flex applicaton from fxml to amf using
1.3.1. My models currently have many attributes that rails knows
about, and flex does not. When rendering fxml that does not seem to
be a problem, but now that I have switched to amf I get an error for
every attribute I do not have defined in a flex model. Such as

ReferenceError: Error #1056: Cannot create property photoFileName on
railpro.models.User.

Does this matter? Should I fix it? If so how?

I am guessing I could just filter out what is needed on the rails end,
or add all attributes on flex end. Perhaps there is a better solution,

Thanks,

Larry

Hi Larry:

I think you could check your model.yml and then re-run script/generate rx_yaml_scaffold again.

 When running this generator, read the questions it asks and say n for every rails/flex file-group except for the class you need to update, and say y. Of course, if this is the first time you do it, create a backup of your whole project.

A beautiful feature restfulx generators have is this, it asks which you want to skip/overwrite, so you could update your model.yml  every time you want(eg.: to update a model by adding/changing/removing a field).

A last thing, although this is or not your first time re-running this generator, always create a backup at least of the flex/rails files from the model which you want to update if you want to keep any change in the files you've done before; so backup the files, run the generator and then write back by hand the changes you want to keep from the old file to the one you want setup.

Hope this helps.

Thanks for the response. I have been upgrading the same application
since the Ruboss days, and I haven't ran a generator or updated my
model.yml file in a while. I could, but I guess I am more wondering
if it makes sense for rendering fxml, the server can send fields that
are not model properties in flex, but for amf every field sent needs
to have a corresponding model property. If that is true, is it
recommending to filter on the server end, or add the properties to
flex. Also Am I doing something wrong here?

Thanks.

Hi Larry,

AMF is a much stricter format than JSON or XML, it's essentially byte code that you just plug into Flash VM. If you have some attributes that are there in Rails but not there in Flex model you should filter them out on rails-end before serializing.

Thanks Dima, that makes sense.
