Hi,
This is my first attempt at a pyramid app, and I could sure use some help.
I am trying to add records to a database table. I can enter values into
the fields specified in the views schema, but when I enter the last field I
get an error:
AttributeError: 'unicode' object has no attribute 'get'
- Expression: "
${form.csrf_token()}
${form.errorlist('seq')}
${form.label('seq', 'Seq:')}
${form.text('seq')}
"
Oddly, the error message shows the first field. And no data is committed
to the database table. Here is the source for my views.py:
import formencode
from operator import itemgetter
from pyramid.response import Response
from pyramid.view import view_config
from pyramid_simpleform import Form
from pyramid_simpleform.renderers import FormRenderer
from pyramid.renderers import render
from sqlalchemy.exc import DBAPIError
from .models import (
DBSession,
MyModel,
)
class AddTreeSchema(formencode.Schema):
allow_extra_fields = False
seq = formencode.validators.Int(not_empty=True)
dbh = formencode.validators.Int(not_empty=False)
merch = formencode.validators.Int(not_empty=False)
species = formencode.validators.String(not_empty=True)
@view_config(permission='post',route_name='tree_add',
renderer='templates/tree_add.pt')
def tree_add(request):
target = request.params.get('target')
session = DBSession()
if target:
target = Trees.get_by_id(target, with_joinedload=False)
if not target:
return {}
form = Form(request, schema=AddTreeSchema)
if 'form.submitted' in request.POST and form.validate():
session = DBSession()
tree = Tree(
seq =form.data['seq'],
dbh =form.data['dbh'],
merch=form.data['merch'],
species=form.data['species']
)
session.add(tree)
headers = remember(request, seq)
return {
'form': FormRenderer(form),
}
Here is the template "tree_add.pt":
<html metal:use-macro="load:global_template.pt">
<div metal:fill-slot="content">
<h1>tree_add</h1>
<tal:block metal:fill-slot="content">
<div class="instructions">
<p>You are adding a tree</p>
</div>
<p>Please submit your tree.</p>
${form.begin(request.route_url('tree_add'), id='tree_add_form')}
<fieldset>
${form.csrf_token()}
${form.errorlist('seq')}
${form.label('seq', 'Seq:')}
${form.text('seq')}
<br />
${form.errorlist('dbh')}
${form.label('dbh', 'DBH:')}
${form.text('dbh')}
<br />
${form.errorlist('merch')}
${form.label('merch', 'Merch:')}
${form.text('merch')}
<br />
${form.errorlist('species')}
${form.label('species', 'Species:')}
${form.text('species')}
<br />
${form.submit('form.submitted','tree_add',class_='submit')}
</fieldset>
${form.end()}
</tal:block>
</html>
I am surely missing something. Thanks much for any help!
Tom
