[Rails] question about post changes for a list of objects once

[ChongQing Xiao]

I see. So in the controller, I just manually get the ID and update each
ID with the data in the fields.

Thanks

It's not necessarily a _Rails_ standard way to handle this, but it's a
simple enough solution---for each field, set up the inputs as
array-style inputs and include the record's id:

<input type="text" name="myobjects[<%=obj.id%>][some_field]" />

Then, in the receiving controller, @params['myobjects'] should be a
collection of the input values keyed on each id, i.e.:

@params['myobjects'][1]['some_field']
@params['myobjects'][24]['some_other_field']
etc.

At least, this is the way, I'd expect @params to behave---anybody know
differently?
