referencing the object id from clean validation methods

[simon101]

Hi

I am using ModelForms to create forms from the models, and using the
clean_field and clean methods to validate the fields and form data as
a  whole.  I get the self.cleaned_data[] dictionary which contains all
the cleaned up data from the html form, but  it doesn't contain the id
for the object id for the object which the ModelForm pulled it off.

Anyone got any ideas how to fix this?  My code looks like this.

class Contract(db.Model):
storage_required = db.BooleanProperty
(verbose_name="storage_required")

class ContractForm(ModelForm):
storage_required = fields.BooleanField()

class Meta:
model = Contract

def clean_storage_required(self):
stor_req = self.cleaned_data['storage_required']
obj_id = ?

btw I am using gae but this shouldn't affect this I think.

Thanks guys

Simon

looping through form.errors in templates

[simon101]

Hi

I've noticed that there have been changes in form error processing for
templates when I've been updating some old code to work with django
1.0.2 from 0.96. My code for displaying errors at the top of the pages
looked like this in 0.96:

{% if form.has_errors  %}
Please correct the following error{{ form.error_dict|
pluralize }}:

{% for elem in form.error_dict.items %}
{{ elem.0 }}: {{ elem.1.0 }}
{% endfor %}

{% endif %}

I've had to replace form.has_errors with form.errors, as shown below:

{% if form.errors %}
Please correct the following error{{ form.errors|pluralize }}:

{% for elem in form.errors %}
{{ elem }}: 
{% endfor %}

{% endif %}

However the new code shown above only displays the field name and not
the actual error text.  What's the syntax for showing the actual error
message on form.errors.

Thanks for any help

problem with custom validator and booleanfields

[simon101]

Hi

I have a model with a boolean field which has a custom validator
defined in the validator_list parameter.  The validator has to run
whenever the form is submitted, whether the checkbox is ticked or not.
I have set the 'always_test' parameter to true for the validator, but
the validator still only gets called when the box is ticked.  I have
found that the 'always_test' parameter works fine for other types of
field, it just appears to be a problem with booleanfields.   Relevant
sections of the model are pasted below:

class Order(models.Model):

def stor_all(field_data, new_data):
   ..validator code goes here
stor_all.always_test = True

   storage_all = models.BooleanField('All to be delivered to
storage?', null='true', validator_list = [stor_all])

Has anyone else encountered this problem and is there a fix for it?

Thx in advance for any help.

Simon

validator_list with checkboxes

[simon101]

My first post, so hi everybody.

I have a model that has a checkbox field called storage_Required.  The
field has a custom generator defined  in the validator_list parameter.
The validator needs to be  run whenever the form is submitted, whether
the checkbox is ticked or not.   Unfortunately the validator is  only
run when the checkbox is ticked.   I have tried defining the
always_test parameter to true, but this doesn't seem to work for
checkboxes, although it works fine for other types of field.  Relevant
code is posted below:


class Order(models.Model):

def stor_valid(field_data, new_data):
..  code here
stor_valid.always_test = True

storage_Required = models.BooleanField(null='true', validator_list
= [stor_valid])

Has anyone else encountered this problem?  If so is there a ticket
outstanding with a patch available, or am I just missing something
really stupid here?

Thx in advance for any help.

Simon
