Here's my simplified take on L's problem. Maybe someone can offer some
advice.
Suppose one would like users to edit multiple records on one screen;
set a BooleanField for multiple records, say. What would be the best
way to go about passing the form fields to the template?
One could create a custom manipulator containing a load of check boxes
tied to the different items or one could create an ChangeManipulator
for each record and pass a list of FormWrappers to the template.
For the simple tick box example custom manipulators would be the way to
go but adding in a couple more layers of complexity means that a load
of manipulators could be best.
The idea would be so that one could do something like this (error
fields needed IRL, obviously):
{% for form in list_of_forms_generated_from_list_of_manipulators %}
<label for="id_myFirstFormField">My First Form Field:</label> {{
form.myFirstFormField }}
...
<label for="id_myLastFormField">My Last Form Field:</label> {{
form.myLastFormField }}
{% endfor %}
request.POST['myFirstFormField'] et cetera would then contain a list of
the different values as entered by the user (a list of Trues and Falses
in the case of the checkboxes).
Can anyone offer any tips on what would be the best way to go about
things? A list of ChangeManipulators seems the neatest solution but
I'm a little worried about the overhead of creating them and getting
form fields for each one.
Thoughts?
