So, this is my problem..
I need to generate forms dynamically with input names that may change
in some circumstances. This means that i can't use pre-determined
method arguments to retrieve the input from these forms.
Even if i did these forms are often too big (with many input fields)
and i can't keep mapping all of them with method arguments.
So i (probably) need widgets... TableForm widgets (?)... I've tried
some things (from the book)...
I did something like:
class TableFormDesc(widgets.WidgetsList):
fields = []
options = {"option1":"value1","option2":"value2"} #just for test
for option in options.keys():
fields +=
[widgets.TextField(option,default=options[option])]
print fields
name = "Table Form"
full_class_name = "turbogears.widgets.TableForm"
for_widget = widgets.TableForm("TableForm",
fields,
action="%s/save" % full_class_name,
submit_text="Submit")
template = """
<div>
${for_widget.display(disabled_fields=["reserved"])}
</div>
"""
@expose()
@validate(form=name) #this is probably wrong...
def save(self, **kw):
return """Received data from TableForm:<br />%r""" % kw
save = expose()(save)
On the template i have:
...
<form xmlns:py="http://purl.org/kid/ns#";
name="${name}"
action="${action}"
method="${method}"
class="tableform"
py:attrs="form_attrs"
>
<div py:for="field in hidden_fields"
py:replace="field.display(value_for(field),
**params_for(field))"
/>
<table border="0" cellspacing="0" cellpadding="2"
py:attrs="table_attrs">
<tr py:for="i, field in enumerate(fields)"
class="${i%2 and 'odd' or 'even'}"
>
<th>
<label class="fieldlabel" for="${field.field_id}"
py:content="field.label" />
</th>
<td>
<span py:replace="field.display(value_for(field),
**params_for(field))" />
<span py:if="error_for(field)" class="fielderror"
py:content="error_for(field)" />
<span py:if="field.help_text" class="fieldhelp"
py:content="field.help_text" />
</td>
</tr>
<tr>
<td> </td>
<td py:content="submit.display(submit_text)" />
</tr>
</table>
</form>
...
I confess that i still don't understand all code presented above, so
examples would be very welcome.
The output error is:
